Privacy policy
Effective November 6, 2026
Mines Rival is a minesweeper game run by Sheffer Global LLC ("we"). This policy explains what we keep about you when you play in the app or at minesrival.com, why, and how to delete it. Questions: hello@minesrival.com.
What we collect
| What | When | Why |
|---|---|---|
| A random player ID | Automatically, the first time you play (a guest account) | To keep your rating, games and progress |
| Email address and password | Only if you sign up | To let you log in and keep your progress on every device. Passwords are stored encrypted by our sign-in provider; we never see them. |
| Player name and country you choose | When you set them | Shown to other players |
| Profile photo (optional, registered players only) | If you add one | Shown to other players with your name. We keep only a small square copy. Remove it any time from your profile; photos reported by other players are hidden and reviewed. |
| Games and progress: match results, scores, ratings, league trophies, puzzle and lesson progress | As you play | Ratings, matchmaking, leaderboards, leagues, game history and reviews |
| Friends, clubs, challenges, blocks and reports | When you use them | To run those features and keep the game safe |
| Device type: phone, tablet or computer | When you play online | Each has its own rating and players are matched on the same type |
| Puzzle statistics (which puzzles are solved or missed) | As you play | To tune puzzle difficulty |
In matches, players can only send preset reactions (phrases like "Good luck" and emojis); nothing can be typed. Reactions are sent live to your opponent and not stored.
We do not collect your contacts or photos, and we do not sell your data. Ads for free players are covered below.
What other players see
Your player name, country, photo (if you added one), rating, game results, league standing and club membership. Your email address is never shown.
Who processes the data for us
- Supabase: database, sign-in and live matches (servers in the United States)
- Netlify: hosts the minesrival.com website
- Apple App Store and Google Play: app downloads and payments, under their own privacy policies
- Google AdMob and AdSense: ads for free players
- RevenueCat: confirms Premium purchases
- AppsFlyer: measures which of our ad campaigns led to an app install (apps only)
- Paddle: sells Premium on minesrival.com as our reseller (Merchant of Record) and handles payment, tax and receipts, under its own privacy policy
Like any online service, these providers process your IP address to deliver the game and protect it from abuse.
Advertising
The free version shows ads. In the app they come from Google AdMob, and on the website from Google AdSense. To show and measure ads, Google may use your device's advertising identifier, IP address and general location, and information about how ads are seen and tapped, under Google's own policies.
- On iPhone and iPad, ads are only tailored to your interests if you allow it when Apple asks ("Allow tracking"). If you say no, you still see ads, but they aren't personalized.
- In the European Economic Area, the UK and Switzerland, we ask for your consent first; you can change your choice at any time.
- Premium members see no ads.
Website analytics and cookies
On minesrival.com we use Google Analytics to understand how visitors find and use the site (pages viewed, where visitors came from, device type, approximate location, and website purchases). In the EU, UK and Switzerland these cookies are off unless you accept them, and you can change your choice any time with Cookie settings. The apps don't use Google Analytics.
Measuring our ad campaigns (apps only)
We advertise Mines Rival on Facebook, Instagram, TikTok, Apple and Google. To learn which campaign brought a player, the apps use AppsFlyer. It receives install and app-open events, your player ID, your device's advertising identifier (on iPhone and iPad only if you allow tracking), device type, and IP-based country, and shares campaign results with those ad networks. We use it only to measure our campaigns, not to show you ads. Your choices under Advertising above apply here too.
Weekly Insights
To give Premium members a weekly Insight, we keep a small summary of your play on your account: minutes played per day and how many times a few minesweeper techniques were missed. It contains no game boards and is deleted with your account.
Purchases
Premium is bought through the App Store, Google Play, or on minesrival.com through Paddle. We never see your card details. We use RevenueCat to confirm purchases and keep your Premium linked to your Mines Rival account; it receives your player ID and your purchase history (product, dates, country).
How long we keep it, and how to delete it
We keep your data while your account exists. You can delete your account at any time in the app: More → Settings → Delete account (or without the app: minesrival.com/delete-account). This immediately erases your account, sign-in, rating, friends, clubs, league entries and progress from our servers, and clears the game's data on that device. Games you played against others may stay in their history without your name. Server backups are overwritten within a short period.
You can also ask us by email to see, correct or delete your data: hello@minesrival.com. We answer within 30 days.
Children
Mines Rival is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child under 13 has an account, email us and we will delete it.
Your rights
Depending on where you live (for example under the GDPR in Europe or the CCPA in California), you may have the right to access, correct, delete or export your data, and to object to how it is used. Email us to use any of these rights.
Security
Data travels encrypted (HTTPS), and each player can only read and change their own private data.
Changes
If we change this policy, we will update the date at the top and, for important changes, tell you in the game.
