# Rain Viewer

> Real-time weather radar service. Tile pyramids regenerated every 5 minutes from NOAA, EUMETNET, and 1000+ regional radar feeds. Operating since 2018 with apps for iOS, Android, the web, and a public Weather Maps API.

Coverage spans 150+ countries through our own processing of public and partner radar networks. The product targets users who need precise local rain timing - storm chasers, severe-weather news desks, drone operators, agriculture, logistics - rather than 7-day forecasts. Updates land on the map roughly 2-5 minutes faster than competitors that re-host third-party tiles.

#### Frequently Asked Questions

- Which features are included in Rain Viewer Premium and not in the free version?
  Premium adds storm direction arrows, advanced 2-hour rain radar forecast, real-time 5-minute radar updates, 48-hour weather archive, 14-day forecast, support for 20 saved locations, ad-free experience, and tropical storm tracking. The free version covers basic radar viewing and limited forecast horizon.
- Can my Rain Viewer Premium subscription be shared with my family across multiple devices?
  Yes — a Premium subscription supports family sharing via Apple's Family Sharing on iOS and Google Play family library on Android. Up to five family members can use the same subscription on their own devices without paying separately.
- Does Rain Viewer Premium work on both iOS and Android with one purchase?
  No, subscriptions are tied to the app store where you bought them. An iOS subscription only works on Apple devices logged into that Apple ID, and an Android subscription only works on devices using that Google account. Cross-platform sharing isn't supported.
- Is there a free trial available before paying for Rain Viewer Premium?
  Free trials are offered periodically and vary by region and app store policies. Open the app on iOS or Android and tap any premium feature — if a free trial is currently available in your country, the subscription dialog will show the trial duration.
- How accurate is the 2-hour rain radar forecast included in Premium?
  The 2-hour nowcast extrapolates from real radar data using motion vectors, so accuracy is highest in the first 30 minutes and gradually decreases over the full 2 hours. It performs best for steady rain and weakens for fast-developing convective storms.
- Can I cancel my Rain Viewer Premium subscription anytime, and what happens after cancellation?
  Yes — cancel anytime through your Apple ID or Google Play subscriptions menu. You keep Premium features until the end of the current billing period, then revert to the free tier. No partial refunds for unused time, but you can renew anytime.

#### Frequently Asked Questions

- Why does my country show a low radar count, or no coverage at all?
  Radar count reflects publicly accessible Doppler weather radars from official meteorological agencies in each country. Some regions have few radars due to geography, budget, or limited public data publication. Coverage continues to improve as more agencies open their data feeds.
- How is the number of radars in each country calculated for this coverage page?
  We count every active Doppler radar station whose data Rain Viewer currently displays on the map for that country. Stations that exist but don't publish public real-time data aren't included. The number updates automatically whenever a station is added or retired.
- Is Rain Viewer's coverage equally accurate in rural areas and remote regions?
  Coverage quality drops as you move away from radar stations because Doppler radar beams curve and lose resolution at distance. Densely radar-equipped regions like the U.S. and Western Europe have near-uniform coverage; remote mountainous or oceanic areas may show gaps even when the country is listed.
- Will Rain Viewer add new countries or radars to this coverage list over time?
  Yes — we continuously integrate new radar networks as official agencies open their data or as we negotiate access. If your region isn't covered today, follow our blog or check back periodically. Suggesting underserved regions to our team also helps prioritize the roadmap.
- Why does my Rain Viewer map show radar data for a country marked as uncovered?
  Border areas often receive radar coverage from neighboring countries even when their own national network isn't yet integrated. The coverage list reflects countries with their own dedicated radar feed, not areas reachable by overlapping signals from beyond their borders.
- Does Rain Viewer cover everything visible on the radar map, including ocean and Arctic regions?
  Rain Viewer shows everything its source radars can detect, including precipitation over coastal oceans and lakes where ground-based stations have line of sight. Open ocean and high-latitude polar regions usually lack ground radar entirely and are not covered.

#### Frequently Asked Questions

- Where does Rain Viewer's radar data come from for each country listed here?
  Every radar image you see comes directly from the meteorological agency or institute named on this page for that country — for example, the National Weather Service in the United States or Environment Canada. We do not generate radar data ourselves.
- Why doesn't my country appear on the list of Rain Viewer data sources?
  If your country isn't listed, the local meteorological agency either doesn't publish public radar data, publishes in a format we can't currently integrate, or hasn't been added yet. We're always evaluating new sources — reach out if you know of a public feed in your region.
- How often does Rain Viewer update the list of data sources on this page?
  We update this page whenever a new radar network is added or an existing source changes ownership or attribution requirements. Major updates happen a few times per year; small changes happen continuously as we expand coverage in underserved regions.
- Can data providers request changes to how their attribution appears on this page?
  Absolutely — if you operate a radar source listed here and want to update your name, link, or licensing terms, contact us with the change request. We aim to keep attributions current and respect each agency's preferred wording and link target.
- Are all radar data sources on this list freely accessible, or licensed individually?
  Most listed agencies publish radar data under open or public-domain terms, but a few require attribution or have specific licensing. Rain Viewer respects every source's terms; this page exists precisely so providers receive proper credit for the data we use.
- Can I use radar data shown in Rain Viewer for my own project or publication?
  Radar data shown in Rain Viewer comes from third-party agencies, not from us — usage rights depend on each source's licensing. For most public data you can use it with proper attribution to the originating agency. Check the source's own terms before publishing.

## API

### API Documentation
URL: https://www.rainviewer.com/api.html

This API is available for personal and educational use only.

#### Terms of Use

- The API is free for personal or educational use.
- We do not guarantee the availability of radar data. We do not conclude contracts with owners of this data. The reason is that the owners can ask us to remove their data from Rain Viewer, change the format, or stop sharing the data. We are trying to keep radar data for as long as possible, but sometimes the owners just stop providing the images.
- You can change any image received by this API without any restrictions (for example, apply a custom color scheme to the images).
- We kindly ask you to mention the Rain Viewer API as a source of the data on your website with a link: https://www.rainviewer.com/

#### Available APIs

- Weather Maps API - Tiled past radar data maps

#### Additional Information

- Single Radar Data : Source radar images
- Color Schemes : Color scheme and color table
- Rain Viewer API Status Page : API status, performance and uptime information
- Data Sources : Links to original radar data providers

#### Frequently Asked Questions

- Is the Rain Viewer API completely free to use, even for production projects?
  Yes — the public Weather Maps API is free for personal, educational, and small-scale community use. There's no fee or paid tier currently, but the free service comes without SLA guarantees and is not intended for high-volume commercial applications.
- Do I need to register or obtain an API key to access Rain Viewer endpoints?
  No registration or API key is required for the free tier. You can fetch the JSON endpoints and tile URLs directly from your application. We recommend caching responses on your side to reduce load and improve your app's reliability.
- What attribution does Rain Viewer require when I use the API in my application?
  You must display credit such as "Weather data by Rain Viewer" with a link back to rainviewer.com somewhere visible in your app or website. Attribution is mandatory under the free terms of use and helps us continue offering the API at no cost.
- Can I use the Rain Viewer API commercially, or only for non-commercial projects?
  The free tier targets personal, educational, and small community projects. For high-volume traffic, commercial integration, or any use case where you depend on guaranteed availability, get in touch — bespoke commercial terms are arranged case-by-case.
- Are there rate limits or guaranteed uptime for the free Rain Viewer API?
  There are no hard rate limits posted, but please cache aggressively and avoid hammering endpoints — abuse may result in your IP being blocked. We don't publish an SLA; the API is provided best-effort. Always include retry logic and graceful degradation in your client.
- What kind of data can I retrieve through the Rain Viewer API right now?
  The Weather Maps API exposes radar tile URLs, timeline metadata for the past 2 hours plus nowcast frames, and color scheme variants. You can build map overlays, automated weather notifications, embedded radar widgets, and similar applications using only this endpoint.

path | Base path for the images of that frame. For information on its usage, refer to the next How to use host and path information section of this page Values: String(255) | /v2/radar/1609401600

##### How to use host and path information

You should use the host and path data from the API as a part of the URL. All available URLs and their parameters are described below.
Each url starts with {host}, where:
- {host} is a host from the Root Object of this API.
URL | Description
{path}/{size}/{z}/{x}/{y}/{color}/{options}.png | Radar data: displays one tile with the composite radar reflectivity data, with specified size, color scheme, and additional options.
{path}/{size}/{z}/{lat}/{lon}/{color}/{options}.png | Radar data: same as the link above, but with the center at specified coordinates (EPSG:4326) with desired zoom size. Great for widgets.
Parameters:
- {x}, {y}, {z} - x, y, and zoom level of the tile that you want to download. Maximum zoom level is 7. Read more about tiles
- {lat}, {lon} - latitude and longitude of specific coordinates accordingly. Decimal format. Must contain a dot in the number. Example: -32.7892, 108.67821.
- {size} - image size, can be 256 or 512.
- {color} - the color scheme ID. See Color Schemes .
- {options} - list of options separated by the _ symbol. For example: ‘1_0’ means smoothed (1) image without snow color scheme (0). Two options are available: {smooth}_{snow}
- {smooth} - blur (1) or not (0) radar data.
- {snow} - display (1) or not (0) snow in separate colors on the tiles.

##### Weather Radar Coverage

Additionally, one more product is available: the weather radar coverage mask. This mask shows where weather radar coverage is available (transparent areas) and where it is not (black areas). We don’t update this mask often. The links are the same as for radar products, but without options and color scheme.
URL | Description
/v2/coverage/0/{size}/{z}/{x}/{y}/0/0_0.png | Coverage tile: where radar data is available (transparent areas) and where it is not (black areas).
/v2/coverage/0/{size}/{z}/{lat}/{lon}/0/0_0.png | Coverage data as above but for specified center coordinates (latitude, longitude).

#### Examples

Basic HTML + JS (Leaflet) example: github.com/rainviewer/rainviewer-api-example

### Hurricane Radars - world live tracking map of hurricane
URL: https://www.rainviewer.com/hurricane-tracker.html
Thanks to Rain Viewer, you can find out where are there hurricanes 🌪 Select your city or region now & view the latest radar with hurricanes ✓ Updated every hour!

#### Hurricane Tracking Map

Tropical storms are areas of extremely low pressure on the earth’s surface. A tropical storm with a wind speed greater than 73 mph belongs to the category of hurricanes. Strong hurricanes of category 2 and higher can cause natural disasters and damage. Therefore, it is crucial to recognize them beforehand and keep the situation under control. A live map of these natural phenomena would help to detect hurricane evacuation zones, warn about a disaster such as flooding, and contribute to public safety.

##### Active Hurricanes

Our hurricane radar page allows you to track the movement of hurricanes and tropical storms on the map. To find out where the actual storm is currently moving, click the icon in the upper-right corner of the map. You will see chains of colorful dots forming the past, current, and predicted path of a hurricane, cyclone, or tropical storm. The movement area forecast predicts a zone where a cyclone can go with the most probable path in the center of the zone.
Different types of tropical storms are marked with different colors on the map:
- Tropical Depression (<38 mph)
- Tropical Storm (39-73 mph)
- Category 1 Hurricane (74-95 mph)
- Category 2 Hurricane (96-110 mph)
- Category 3 Hurricane (111-129 mph)
- Category 4 Hurricane (130-156 mph)
- Category 5 Hurricane (157 mph or higher)

#### More in app

In the Rain Viewer app, you can dive deeper into upcoming tropical storms, from early formation to landfall and beyond.

##### Storm Timeline

Track the storm’s full journey. Tap any point on the path to see real-time wind speed, category, and direction. See where it started, how fast it's moving, and where it’s likely to hit next.

##### Storm Details

Category 1 or Category 5, you’ll know exactly what you’re dealing with. Decode intensity with one glance and decide if it’s time to head to the cellar or just secure the patio furniture.

##### Push Notifications

Get notified the moment a storm approaches your area. Our alerts are timely, hyper-local, and designed to give you enough time to act - whether that means gearing up or getting out.

##### Can a weather radar detect hurricanes?

When a hurricane is within approximately 325 km or 200 miles off the coast, a land-based weather radar can detect it. Such radars deliver up-to-date data about rain intensity, tropical storm movement, and speed. As a result, the National Weather Service can issue short-term warnings for intense winds, tornadoes, and flooding in certain areas. Rain Viewer has access to data from over 1000 radars around the world. Thus, we can provide the most actual information about the current cyclones and hurricanes, updated in real time.

##### How to track a hurricane on a map?

To track a hurricane on our map, you should turn on the tropical storm tracks. To do it, click the icon in the top-right corner. This will display the chains of dots marked with different colors that represent the scale of the tropical storm.

## About

### About Rain Viewer
URL: https://www.rainviewer.com/about.html
The Rain Viewer website and apps for iOS and Android provide weather forecasts and warnings for precipitation, storms and various other disasters.

#### About Rain Viewer

We believe everyone deserves accurate rain prediction.
At MeteoLab Inc., we’re on a mission to deliver the most precise precipitation forecasting technology directly to your fingertips. What started as a simple idea in 2015 has grown into the world’s most comprehensive weather radar platform, trusted by millions of users across many countries.

#### Our Mission

Every day, people make decisions based on weather forecasts. Will it rain during the school pickup? Should I plan that outdoor event? Can I safely drive through this storm? These aren’t just questions-they’re moments where accurate weather data can make the difference between safety and danger, success and disappointment.
We’re passionate about solving this challenge through technology that processes over 1,000 weather radars globally, delivering sub-kilometer precision with updates every 5 minutes. Our goal is simple: provide the most accurate rain prediction available anywhere, accessible to everyone.

#### The Team Behind the Technology

We’re a focused team of 11 engineers, designers, and weather enthusiasts who believe that exceptional forecasting comes from combining cutting-edge technology with deep meteorological expertise. Based across multiple time zones but united by our obsession with weather accuracy, we work together to push the boundaries of what’s possible in precipitation prediction.
Every member of our team contributes to our core mission. From our iOS and Android developers who optimize radar rendering to achieve 60fps performance, to our backend specialists who process terabytes of radar data in real-time, to our designers who make complex meteorological information beautifully simple-we’re all driven by the same goal.

#### Our Founder’s Story

Oleksii Schastlyvyi, our CEO and founder, has been obsessed with rain since 2006. As a software engineer with a background from Ukraine’s National Technical University, Oleksii combined his technical skills with his passion for meteorology to create something that didn’t exist: a weather app that provides meteorologist-grade radar data to everyday users.
Starting as a backend engineer in 2015, Oleksii built the first Rain Viewer prototype, then developed the iOS app, followed by Android, all while continuously upgrading our web platform. His vision was simple but ambitious-make professional-quality weather radar data accessible to everyone, not just meteorologists.
Today, Oleksii leads our team with the same hands-on approach and technical passion that started Rain Viewer. His commitment to accuracy and innovation drives every decision we make, from choosing which radar technologies to implement to designing user experiences that make complex weather data immediately understandable.

#### What Makes Us Different

We process our own data. Unlike most weather apps that rely on third-party providers, we collect, process, and analyze radar data directly from over 1,000 radar stations worldwide. This means faster updates, higher accuracy, and complete control over data quality.
Privacy is fundamental. We don’t collect your personal data, don’t sell your information, and don’t track your location unless you explicitly allow it for weather alerts. Your privacy isn’t a feature-it’s our foundation.
Professional tools for everyone. Our PRO Radar technology provides the same raw, high-resolution data that meteorologists use, but through an interface that anyone can understand. Multiple radar products, multiple tilt angles, and sub-3-minute updates give you unprecedented insight into approaching weather.
Global coverage, local precision. From the smallest rural town to the largest metropolitan area, our network of 1,000+ radars provides coverage across 75 countries with sub-kilometer accuracy. Whether you’re in rural Montana or downtown Tokyo, Rain Viewer delivers precise local forecasting.

#### The Technology We’re Building

Rain Viewer isn’t just an app-it’s a platform built on cutting-edge meteorological technology:
- Real-time radar processing from 1,000+ global sources with 5-minute updates
- PySTEPS nowcasting technology providing 2-hour precipitation forecasts updated every 5-10 minutes
- 60fps OpenGL/Metal native rendering for smooth, responsive radar animations
- Professional radar products including reflectivity, velocity, and dual-polarization data
- Global satellite coverage for precipitation detection in areas without radar infrastructure

#### Our Impact

Since 2015, Rain Viewer has helped users avoid rain over 4.7 million times, provided critical warnings for 86 tropical cyclones, and delivered reliable precipitation data during countless storms, outdoor events, and daily decisions.
But the numbers only tell part of the story. Every day, we receive messages from users who avoided dangerous driving conditions, successfully planned outdoor weddings, or simply stayed dry on their way to work because Rain Viewer gave them accurate, timely information that other apps couldn’t match.

#### Looking Forward

Weather prediction is evolving rapidly, and we’re committed to staying at the forefront. We’re continuously expanding our radar network, improving our forecasting algorithms, and developing new ways to make weather data more accessible and actionable.
Our upcoming innovations include expanded global coverage and even more precise short-term forecasting. But our core mission remains unchanged: deliver the most accurate rain prediction possible, accessible to everyone who needs it.

#### Why We Do This

Weather affects every aspect of our lives, yet most people have access only to generic forecasts that treat entire regions the same way. We believe you deserve better. You deserve to know exactly when rain will start at your specific location, how heavy it will be, and how long it will last.
We’re building Rain Viewer because we believe that better weather information leads to better decisions, safer communities, and more successful lives. When you can trust your weather forecast down to the minute, you can plan with confidence and stay prepared for whatever nature brings.
Rain Viewer is developed by MeteoLab Inc., a weather technology company founded in 2015 in Naples, Florida. Our team operates remotely across multiple countries, united by our commitment to advancing precipitation forecasting technology.

### Frequently Asked Questions (FAQ) - Support of Rain Viewer

A section with users' most frequently asked questions regarding using the Rain Viewer application. If you did not find the answer to your question, please contact us at support@rainviewer.com.

#### FAQ

- I see the "Last location update" notification from the app. What does it mean?
  Our app has always needed some background activity to properly update the weather information and current location. The "Last location update" notification is a visible identifier of our background activity. It appears after you grant our app long-time access to your location and then turn on the Location Update Notification option in settings. You can disable this option at any time in the app settings. However, please keep in mind that the app won't be able to update the location in the background when the option is turned off. It is acceptable to turn it off for the days you spend in the same location. But this option helps us get more accurate data about your location (and therefore the weather in your area as thus) when you change your location throughout the day.
- How do I save/delete a favorite location?
  Saving a favorite location
  To save a favorite location, please go to the weather info page (a star icon at the bottom menu)
  -> tap the Search & Add button (the "plus" button top right corner)
  -> find the location via the search field
  -> tap the location name. A page with the weather info for this location should appear. In the top-right corner of this page, tap Add to save the selected location.
  
  Deleting a saved favorite location
  To delete the saved location, please go to the location weather info page (a star icon at the bottom menu)
  -> tap the list of your locations at the top-left corner
  -> horizontally swipe the location you want to delete until the red "delete" button appears.
- I cannot find my city name on the map or the name of my town is misspelled on your map. Why?
  Rain Viewer is created to process weather data. Unfortunately, we cannot influence cartographic data because we use default maps set by the device's OS. Meanwhile, if you cannot find the location by its name, you can save it by long-tapping the map in the required area.
- I want to use my subscription on devices with different OS (Android, iOS) and different store accounts (Google Play, AppStore, Huawei AppGallery). Can I?
  Unfortunately no, sorry. Please kindly note that it is not possible to transfer purchases and subscriptions between different stores (e.g., AppStore and Google Play).
- I'm a Premium user but after the reinstall, I no longer find any of my premium features and/or start seeing third-party ads. How do I return my subscription privileges?
  If your subscription hasn't been reactivated automatically after some manipulations, then please try to restore it manually. Follow these steps: Settings - Rain Viewer Premium - Show all Premium Features, and then tap Restore Purchase at the bottom of the screen. If you have an Android device, just wait a little: Rain Viewer checks your purchases automatically when you visit this screen. If nothing happens, check whether your device's main account matches the one you previously made a purchase on. Please note that you cannot transfer purchases and subscriptions between the AppStore and Google Play.
- Rain Viewer typically shows the accurate weather data for my location. But today the radar in my region is operating poorly or is offline. Is this Rain Viewer's fault?
  Despite the use of weather radar data, we don't own these radars, so unfortunately we cannot influence their operation. Considering this, we can only collect the data from the mentioned radars, not generate it. You can check whether a radar in your area is working fine today via Menu - Single Radar mode (tap the radar to get more info). If you believe that our app shows the wrong information about the radar's current state, please write us an email providing the trusted source of information for analysis. Thank you.
- I look at the weather radar animation layer and see strange circles/figures instead of precipitation for my area. Is there something wrong with my app?
  The app is probably fine. It looks like the weather radar in your area delivers broken data. In most cases, this situation is temporary. The main goal of Rain Viewer is to collect and process weather radar data in 80+ countries. But unfortunately, we do not own these radars and have no influence on their operation. Considering this, we can only collect the data from the mentioned radars, not generate it. If you believe that our app shows the wrong information about the radar's current state, please write us an email providing the trusted source of information for analysis.
- The app either crashes or freezes. Is there anything I can try before contacting support?
  For Android:
  Please try the Clear Data option (Device settings - Apps - Rain Viewer - Storage - Clear data), then delete the app and install the latest version from the store.
  For iOS:
  Please try to delete the app and install the latest app version from the store.
- I'm not getting any notifications from the app. Is there anything I can try before contacting support?
  Please make sure that you have granted our app access to send notifications to your device and that the app is allowed to update the device's location info. Please also make sure that the notifications are turned on for the wanted location (app settings) and that the weather radar in your area is online these days (app settings, Single radar mode, tap the radar for more info).
- I seem to only get information about heavy rain, but no information about the drizzles, etc. Any suggestions?
  Please try to manage the intensity of precipitation to be displayed (app settings - Radar Overlay - Minimal Precipitation Intensity - the Full Range option).
- Does Rain Viewer work well in any region? If no, then how can I check whether it works in my region?
  Rain Viewer collects and processes data from weather radars in 80+ countries. These radars are not our property, and hence we cannot influence their quantity and quality of work. Not all areas are covered by weather radars. To start working with Rain Viewer, please verify whether the radar covers your region by going to Settings - Radar Overlay - Coverage. The gray spaces on the map layer show areas that are not covered by weather radars. Therefore, Rain Viewer cannot provide accurate radar precipitation information here. We can only provide the long-term forecast (24 hrs/7 days) for such areas. If the radar map covers your current location, then please verify that the radar in your area is operating normally today (Menu - Single Radar mode - tap the radar to get more info).
- Can I use Rain Viewer with Internet and/or GPS off?
  To work properly, Rain Viewer should have at least the Internet access. Rain Viewer's work is based on collecting and processing data from weather radars in your area. The app should periodically check your location and request radar data for that specific location. Rain Viewer can work without GPS, but it won't display your location.
- What is the difference between weather radar data and weather forecast?
  Weather radars provide past and current info about the movement of precipitation. This is the actual info based on the sky screening as is. Radars typically detect moderate to heavy precipitation with extreme accuracy, though they may sometimes have nuances with the detection of light rain or drizzle. Radar data also allows you to build a short-term (up to 90 mins) accurate precipitation trajectory. A weather forecast is an algorithm that makes predictions for further long-term precipitation movement. Forecasts are based on mathematical formulas and may not always be accurate for the next hour.
- What's the difference between the radar and satellite map layers?
  The radar layer can show more details than the satellite layer. Radars can even detect small storm cells, while satellites see precipitation globally all over the Earth. Additionally, radar animation is of higher quality than satellite animation.
- I see the snow for my location on the main map animation. But there is no snow in the animation when I turn on the Single Radar mode. Why?
  The data for the snow layer comes from the source other than weather radars. Specifically, it comes from the temperature map with its own database and algorithms. That's why the snow layer is not visible in the Single radar mode. However, it is available in the general animation for the selected location.
- Which maps does Rain Viewer use? May I use my own maps in Rain Viewer?
  Rain Viewer uses the default system maps (e.g., Google Maps for Android system, Huawei Maps for AppGallery version, and Apple Maps for iOS AppStore version). Unfortunately, you cannot maps other than the default ones for our app.
- I want to add a location to favorites but I cannot find it via the Locations Search field. What should I do?
  The search engine may not detect some locations. If so, then please add the location manually. To do it, long tap the required place on the map. This action will redirect you to the option of saving your favorite location.
- The data in radar animation is late for 10-15 mins. How can I fix this?
  The delay may be caused by the long processing period and/or delivery of data from some radars to our server. Weather radars are not our property, so we cannot influence the quality of their work. You can find the exact time of recent radar images in the Single Radar mode.
- I get precipitation notifications in my area, but nothing happens. Why?
  The radar in your region may be extremely sensitive. Please try to choose the different precipitation intensity to be notified about in app settings.
- How do I return my money?
  To request a refund for the purchase made less than 30 days ago:
  - for the Google Play app version, please contact our team with your billing details (purchase date, your name, and billing email connected to your Play Store account);
  - for the AppStore and AppGallery app versions, please contact the App Store/AppGallery support directly because do not have refund privileges on those stores according to their policies.
- I have decided not to pay for the monthly subscription anymore. How do I cancel my monthly subscription?
  You can manage your subscription in your store account. Please note that if you cancel the subscription, you won't be charged for subsequent months. However, there's no refund for the months before the cancellation.
- I purchased Rain Viewer before the summer of 2020, but now the app wants me to buy it again. Why?
  No worries, your purchase is still active, with the premium features of Rain Viewer 1. In the summer of 2020, we released a brand new version of the app, Rain Viewer 2. It contains both the changed subscription plan and new features. The purchase banners relate only to the acquisition of new options. If you aren't interested in the upgrade, then either skip the banner or tap Skip. For more information, [visit our website](/blog/rainviewer-pricing.html){:target="_blank"}
