Maths Defence Privacy Policy
Maths Defence collects no data about you. None at all.
Google Play requires every app to publish a privacy policy, even one that collects nothing. This is that policy, and it is short because there is very little to say.
Last updated: 20 September 2026
What is collected
Nothing. There is no analytics, no crash reporting, and no tracking.
The game makes no network requests. It contacts no server, ours or anyone else’s, so there is nothing to send and nowhere to send it. No internet connection is needed to play, ever.
What is stored on your device
So that the game works and remembers where you were, the following is saved in the app’s own storage on your device:
- each player profile on the device: a generated handle, a chosen avatar, the age that was entered, the difficulty tier that age selects, and whether the introduction has been seen;
- progress: research points, which number and operator tiles have been unlocked, and how many runs have been started;
- the run you are part-way through, so closing the game does not lose it;
- which daily challenges have been played, and how they went;
- settings, such as whether the sound is off.
The age is a number used to pick a starting difficulty. Player handles are generated by the game — there is nowhere to type a real name, and nothing you type is stored.
All of it stays on your device. None of it is sent to us or to anyone else, because there is nowhere for it to be sent. Deleting a profile removes that profile’s saved game with it, and clearing the app’s data, or uninstalling it, removes all of it permanently.
Accounts, adverts and payments
There are none. No sign-in, no adverts, no in-app purchases, and no third-party analytics, advertising or tracking services of any kind are embedded in the game.
Children
Maths Defence is built for children and is suitable for all ages. Since it collects no data whatsoever, it collects no data from children either. There are no social features, no chat, no user-generated content, and no way for a child to communicate with anyone through it.
Note that Google Play, as the distributor of the game, may collect information when you download or install an application. That collection is governed by Google’s privacy policy and is outside our control.
Changes
If a future version ever collects anything, this policy will be updated before that version is released, and the change will be described here rather than quietly substituted.
