Magnet Game privacy policy

For the Magnet Game Android app. Last updated 1 October 2026.

Magnet Game ("the app") is developed by Deepankar Garg ("we", "us"). This policy explains what data the app handles.

Summary

The app has no accounts, no advertising and no third-party SDKs, and the game plays fully offline. It keeps your games on your phone. About once a day it sends us usage data, including your finished games and the player names in them, so we can see how the app is used and improve it. It also sends feedback you type in Settings, when you tap Send.

Data on your phone

Your games, History, player names and settings are stored in the app's private storage on your phone. They are deleted if you uninstall the app or clear its storage in Android Settings.

Usage data

In the background, about once a day, the app sends usage data over an encrypted connection to a small service we run on Cloudflare, which stores it in a database only we can read. It contains:

• a random ID the app makes when it is first opened, so we can tell one installation's data from another's. It is not your Android ID, advertising ID or any hardware ID, and it is not linked to your email address, phone number or any account;
• the app version, the Android version, and the phone's make and model;
• for each day the app was used, how many times it was opened;
• your settings: difficulty, field size and display, warnings, lift, snap speed, Face-to-face, haptics, sound, theme, magnets each, the player names and colours on Home, and your Solo best;
• each game once it is in History: when it started, two players or Solo, the player names and colours, the game's settings, every magnet placed (where and when), the scores, and whether it was finished, quit or restarted.

The first time it sends, the app also sends the games already in your History. A game in progress is never sent. A game you delete from History after it was sent is not deleted on our side.

Player names are whatever you type on Home. Use nicknames if you'd rather we didn't see real names.

Cloudflare sees your IP address when the app connects. It is used only to stop the service being flooded, and it is not stored.

We use usage data only to understand how the app is used and to improve it. We don't sell it, share it or use it for advertising. To have it deleted, see "Deleting your data" below. Uninstalling the app stops any further sending.

Deleting your data

To have the data Magnet Game (by Deepankar Garg) has sent us deleted:

1. Email deepankar.garg@indidev.org with the subject "Delete my data".
2. Tell us roughly when you installed the app, your phone's make and model, and the player names you used. That lets us find your installation's data.
3. If you also sent feedback from the app, include a few words of it.

We delete all usage data of the matching installation (its random ID, daily counts, settings and games) and any matching feedback emails, keep nothing, and reply to confirm within 90 days.

If you keep using the app, it will go on sending new usage data; uninstall it to stop. Data on your phone is deleted when you uninstall the app or clear its storage in Android Settings.

Feedback

Settings has a box where you can type feedback. When you tap Send, the app sends what you typed, with the app version, the Android version and the phone's make and model, over an encrypted connection to a service we run on Cloudflare. That service emails it to us and keeps no copy. Nothing is sent unless you tap Send. Cloudflare also sees your IP address, which is used only to deliver the message and to stop the service being flooded.

We keep feedback emails for as long as they help us improve the app. To have yours deleted, see "Deleting your data". Please don't put personal information in feedback that you don't want us to have.

You can also email us directly at the address in Settings. That message goes through your own email account.

Permissions

The app uses two permissions, both granted at install with no prompt: vibrate, for the buzz when magnets merge, and internet, only to send usage data and feedback. It does not use location, camera, microphone, contacts, or any other sensitive permission.

Third parties

The app includes no third-party SDKs, crash reporting or advertising libraries. Usage data and feedback go through Cloudflare, which handles them on our behalf.

Children's privacy

The app is not directed at children and does not knowingly collect personal information from them. If a child's name was used as a player name and you want it removed, see "Deleting your data".

Changes to this policy

If this policy changes, the updated version will be posted at the same address, with a revised "Last updated" date.
