Privacy Policy

Last updated: 27 August 2026

This policy covers the Biofetti mobile app, published by PraoAI.

The short version

This app collects nothing. It has no accounts, no ads, no analytics, and no servers. It does not ask for your name, your email, your school, or your age. Nothing you do in the app leaves your device, because the app has no way to send anything anywhere.

What is stored, and where

Biofetti saves one entry on the device itself. It holds:

• which levels you have played and how many stars each earned
• your Daily Dose streak, your best streak, and the date you last did one
• the Ward's revision cards - which questions you got wrong, which box each is in, and the date each is next due
• which collection slides you have already been shown
• your settings: sound, haptics, reduced motion, and language
• optionally, an exam date and a word for it, if you choose to set one

That last one is the only thing you can type into this app, and it is a date and a label - never a name, an email, a phone number or a school. Like everything else here, it stays on the device and is never transmitted.

The whole entry never leaves the phone or tablet. Deleting the app deletes it. There is no way for us - or anyone else - to read it, because it is never sent anywhere.

One consequence worth knowing: because the save is local and there is no account, there is no backup and no way to move progress between devices. If you lose the phone, reinstall the app, or clear its data, the stars, the streak and the Ward start again from zero. That is the price of a game that has no server, and we would rather say it plainly than quietly add one.

Network use

The app makes no network requests at all. It has no analytics SDK, no advertising SDK, no crash-reporting SDK, no billing SDK, and no social or sharing features. There are no links out of the app.

On Android the released app does not even ask for the internet permission, so it could not reach the network if it tried.

The game is free, so there is no payment path of any kind and nothing to purchase.

Who this app is for

Biofetti is rated 12+ on the App Store and Teen on Google Play, and is aimed at students of about 13 to 19 studying school biology and preparing for entrance exams. It is deliberately not a Kids Category app.

That rating is about the audience, not about what is collected: no personal information is collected from anyone, of any age.

• There is no advertising of any kind, targeted or otherwise.
• There is no account, no sign-in and no profile.
• There is no chat, no messaging, no comments and no user-generated content. The two-player duel is two people sharing one screen; nothing is sent between devices, because nothing is sent anywhere.
• Nothing can be bought. There are no in-app purchases, no subscriptions and no billing code.

Because nothing is collected, there is no personal data to review, correct, or ask us to delete. Deleting the app is the whole of it.

Third parties

The app bundles no third-party services that receive data. Its open-source components - the Flutter framework and its audio and local-storage plugins - run entirely on the device.

We do not sell, share, or transfer data to anyone, because we do not have any.

Changes

If a future version of the app ever collects anything, this policy will be updated before that version ships, and the change will be described here with its date.
