_Effective: 24 October 2026_
Sandmere does not ask for, collect or upload your name, email address, phone number, contacts, photos or any other personal information. There is no account and no login. The only data that leaves your device is what our advertising partners collect automatically to show and measure ads, and what our purchase provider RevenueCat needs to show store prices and verify purchases (an anonymous app user ID, this app's purchase history, and technical data such as device model, operating system version, language, store country and IP address). Both are described below.
On the App Store, the "App Privacy" section of our listing summarizes these practices; on Google Play, the "Data safety" section does. This policy is the full version, and all three say the same thing.
Your best score, level, grains, upgrades, daily streak, goals, Sand Wheel spins and settings are stored on your device only, using the operating system's own app storage. This data is never sent to us. If your device backup (Android Backup or iCloud) is turned on, the operating system may include it in that backup, which Google or Apple runs, not us. Uninstalling the app deletes the copy on the device.
Sandmere contains the following third-party software. Each one is described here, with a link to its own policy.
Sandmere shows ads through Yodo1 MAS, a mediation platform that selects among a group of third-party advertising networks, including Google AdMob and other mediation partners; the exact set can vary by region and over time. To select, serve, measure and prevent fraud on ads, these partners may automatically process:
We do not control which specific partner serves a given ad, and the set of partners can change over time. Yodo1's privacy policy: https://policy.yodo1.com/corporate/en/privacy.html
Google AdMob is one of the networks Yodo1 MAS can call. It receives the same ad data listed above. Google's policy: https://policies.google.com/privacy
Yodo1 MAS also runs its own analytics, provided by ThinkingData, to measure how ads and the app perform. It may process device identifiers and usage events on Yodo1's behalf. ThinkingData's policy: https://www.thinkingai.io/en/privacy-policy
If you are in the EEA, the UK or Switzerland, Google's consent form (User Messaging Platform, run inside our ad provider's software) may be shown when you first open the game so you can choose about personalized ads. On iOS it is skipped if you ask the app not to track you.
Purchases are handled through RevenueCat. To show store prices and to verify and restore purchases, RevenueCat receives:
We never receive or store your payment card details. RevenueCat's privacy policy: https://www.revenuecat.com/privacy
Sandmere is free to play and shows ads: interstitial ads between runs (never before the third run), app-open ads, and optional rewarded videos. A one-time Remove Ads purchase turns off interstitial and app-open ads; optional reward videos stay available.
iOS. Sandmere asks for your permission through Apple's App Tracking Transparency prompt the first time you open the app, before any ad is requested. If you tap "Allow", our advertising partners may use the IDFA to show more relevant ads and to measure them. If you tap "Ask App Not to Track", the IDFA is not shared, ads are less personalized, and the game plays exactly the same. You can change your choice at any time in iOS Settings > Privacy & Security > Tracking.
Android. The app declares the advertising ID permission (com.google.android.gms.permission.AD_ID) for the ad partners. You can reset or delete your advertising ID under Settings > Privacy > Ads.
All platforms. The PERSONALIZED ADS switch on the home screen is on by default. Turning it off asks our ad partners that support it not to sell your data for advertising. It is the opt-out California law asks for, and you can change it at any time.
Reporting an ad. If you see an ad that is inappropriate, tap REPORT AN AD on the home screen. It opens an email to us where you can describe the ad (what it was for, what was wrong with it, and roughly when it appeared). We review these reports.
Sandmere offers optional in-app purchases: grain packs, a one-time starter pack, and Remove Ads. They are processed by Google Play or the Apple App Store, through RevenueCat (section 3.5); on iOS the charge is made to your Apple ID by Apple. Remove Ads can be restored at any time with Restore Purchases (on Home and in the Shop), using your Apple ID or Google account. Grain packs and the starter pack are delivered once, when bought; a restore does not deliver them again. Grains have no value outside the game.
Sandmere is not directed at children under 13 and we do not knowingly collect personal data from them. The app does not require age input, an account, or any personal information to play. If you believe a child has provided data to us or our partners, contact us and we will take steps to delete it.
We do not retain any personal data, because we do not collect any. Data processed by advertising partners and RevenueCat is retained according to their own policies.
Because the app holds no account, we hold no personal data of yours to export, correct or delete. Uninstalling the app deletes the local copy, subject to operating-system backups. Settings > DELETE MY DATA clears game progress, grains, upgrades, daily streaks and goals. Settings, privacy choices and purchase/review bookkeeping are retained; purchase delivery receipts prevent the same store transaction being credited twice. Device backups are managed by Google or Apple, not by us.
To ask for deletion of data held by our partners, email us at indeagamesstudio@gmail.com and we will pass the request on and assist where we can. You can also contact the partner directly:
The third parties we share data with (our advertising partners, Yodo1's analytics provider ThinkingData, and RevenueCat) protect it at the same or an equivalent level as this policy. They may process data in countries other than your own, including the United States, under their own compliance frameworks. We do not ourselves transfer any data internationally, because we hold none.
If you allow notifications, Sandmere schedules a few reminders on your device (after 1, 5, 7, 14 and 30 days without playing, and never at night). On iOS the permission prompt appears once, after your first finished game. The reminders are created on the device itself, contain no personal data, are never sent to us, and can be turned off at any time in your device's notification settings.
After a good game, Sandmere may show the App Store's or Google Play's own rating dialog, and the home screen has a Rate Us link that opens the store page. Any rating or review you leave goes directly to that store; we do not receive it through the app.
If this policy changes in a material way, we will update this page and the "Effective" date above. Continued use of the app after a change means you accept the updated policy.
