Retessera is a free art puzzle, on the web at retessera.art and as an Android app. It is made by Peter Szaraz. It is built to collect as little as possible: there are no ads, no analytics, no tracking cookies, and you never need to give your name, email address or phone number to play.
What stays on your device
The game remembers a few things in your browser's storage, or in the app's storage on Android, so you can carry on where you left off:
- your settings (level, music on or off, Daily or Free practice);
- today's puzzle in progress and your result;
- your nickname and recovery code, if you chose one;
- photos you pick for Free practice. These are only used on your device and are never uploaded.
Clearing the site's data or uninstalling the app removes all of this.
What is sent to Retessera
Only if you choose a nickname for the daily leaderboard:
| Data | Why | Who can see it |
|---|---|---|
| Nickname | To show your score on the leaderboard | Everyone who views the leaderboard |
| Recovery code (stored only in scrambled form) | So only you can post scores under your nickname | No one. It can't be read back, even by us. |
| Daily results: date, level, moves, time, hints used and score | To rank today's leaderboard | Level and score appear on the leaderboard |
Please don't use your real full name, or other personal details, as a nickname. Nicknames aren't linked to an email address, phone number, or device ID.
Messages you send us
The Contact form sends your message, and the name you type, to the developer by email. It goes through Web3Forms, a form delivery service. Messages are used only to reply to you and to improve the game.
Services the game relies on
- Cloudflare hosts the website and the leaderboard. Like any web host, it handles your IP address to deliver the pages and protect against abuse. See Cloudflare's privacy policy.
- Google Fonts supplies the lettering, so your device downloads font files from Google. See Google's privacy policy.
- Web3Forms delivers Contact messages, as described above.
- The Android app opens the game using Chrome, or another browser on your phone. That browser's own privacy settings apply.
We don't sell or share your data for advertising, and nobody else gets it.
Deleting your nickname and scores
You can delete your nickname and every score posted under it, at any time, from inside the game:
- Open the menu and make sure Daily game is selected.
- Under "Playing as …", open Recovery code.
- Tap Delete my nickname and scores, then tap it again to confirm.
The deletion is immediate and permanent. If your nickname is no longer on your device, first enter it with its recovery code ("I already have a nickname") on any phone or computer, then delete it as above. If you've lost the recovery code, write to us with your nickname and roughly when you last played, and we'll remove it within 30 days.
How long data is kept
Nicknames and scores are kept until you delete them, so past leaderboards remain accurate. Contact messages are kept in the developer's email for as long as needed to reply.
Children
Retessera is a general audience game and doesn't ask for anyone's age. Choosing a nickname is optional. Children can play without one, and we ask parents to help younger players pick a nickname that doesn't reveal who they are.
