Privacy PolicyWhat is this? — picture-naming game for 2–4 year olds

Effective date: 22 September 2026

"What is this?" (the "app") is a picture-naming game for young children, published on Google Play by Valerian Pereira. This page explains what the app does with information, in plain language.

The short version: the app collects no personal information, has no accounts, no ads, no analytics, no in-app purchases, and never sends anything you or your child do to us or to anyone else.

Information we collect

None. The app does not ask for, collect, store or transmit any personal information about you or your child — no names, email addresses, contacts, location, photos, recordings, device identifiers or advertising IDs.

What stays on your device

Game progress and settings. Which words have been seen, how many rounds were played, and the settings you choose (voice on/off, thinking time, auto-advance) are saved only in the app's own storage on your device. They are never uploaded. Uninstalling the app deletes them.
Card pictures. Photos are downloaded the first time each card is shown and then kept in the app's cache so the game works without a connection. They are ordinary picture files, not information about you.

Network use

The app uses the internet for one thing: fetching the card photographs. They are served from a public content delivery network (jsDelivr, at cdn.jsdelivr.net), which delivers files from the app's open-source GitHub repository. Like any web server, the CDN receives your device's IP address and the file requested in order to send the file back; the app adds no identifiers to these requests. jsDelivr's own privacy policy is at jsdelivr.com. Once pictures are cached, the app makes no further network requests. No other servers are contacted.

Speech

The app reads each word aloud using the text-to-speech engine built into your device. It does not use the microphone and does not record or listen to your child. The RECORD_AUDIO permission is not requested.

Permissions

The only permission the app declares is Internet, used to download the card photographs as described above.

Children's privacy

The app is made for children aged 2–4 and is designed to be used together with a grown-up. Because it collects no personal information from anyone, it does not collect personal information from children, and there is nothing to review, delete or opt out of. Settings and the "Parent zone" are behind a two-second press-and-hold so they are hard for small children to open by accident.

Third-party content

The photographs come from Wikimedia Commons and Wikipedia under their own open licences; the author and licence of each one is listed inside the app under Parent zone → Photo credits. Displaying them involves no tracking.

Changes to this policy

If the app ever changes in a way that affects privacy — for example if it starts collecting anything — this page will be updated first and the effective date above will change. The app itself will always describe its behaviour honestly in its Play Store listing.
