Privacy Policy
Sand Art · Effective 3 November 2026
This policy explains what information the Sand Art app (“the app”), made by ann520 (“we”), collects and how it is used.
No account, no personal information
The app does not ask you to sign in and does not ask for your name, email address, phone number, contacts, photos or location.
Game progress stays on your device
Your stars, best scores and settings are stored locally on your device. They are not sent to us. Deleting the app deletes this data.
Technical data collected by the game engine
The app is built with the Unity engine. Unity may collect limited, non-personal technical information — such as device model, operating system version and basic hardware statistics — to improve its engine. This is handled by Unity Technologies under its own privacy policy: unity.com/legal/game-player-and-app-user-privacy-policy.
Advertising (Google AdMob)
The app is free and shows ads through Google AdMob: an optional video you can watch to unlock a hint, and an occasional full-screen ad between levels. To serve and measure these ads, Google may collect and process information such as your device’s advertising identifier (only if you allow tracking), IP address, approximate location derived from it, device and app information, and how you interact with ads.
- Tracking permission (iOS): the app asks once whether it may track you. If you decline, ads are still shown but are not personalised using your advertising identifier. You can change this any time in iOS Settings › Privacy & Security › Tracking.
- Consent in the EEA, UK and Switzerland: the app shows Google’s consent form before any ads are requested, and a “Privacy” button on the main screen lets you change your choices later.
- How Google uses this information: policies.google.com/technologies/partner-sites, and Google’s privacy policy: policies.google.com/privacy.
We do not receive your advertising identifier or any personal information from these ads; we only see aggregated reports (for example, how many ads were shown).
Analytics
The app does not include any separate analytics service.
Children
The app is suitable for all ages. We do not knowingly collect personal information from anyone, including children under 13.
Changes
We may update this policy. The effective date above shows when it was last changed.
