Privacy Policy
Sletter.io is a free browser-based word-snake game. We try to collect as little information as possible. This page describes what we do collect, why, and how long it sticks around.
What we store on your device
The game uses your browser's localStorage to remember:
- Your in-game display name
- Music and sound-effect preferences (mute / volume)
- Field colour and (on Android) vibration settings
These values stay on your device. They are not sent to our servers and are not shared with anyone. Clearing your browser's site data removes them.
What we send to the game server during a match
- The display name you chose
- Your in-game movements, picked-up letters, dropped letters, and locked words
- The room you're playing in (party invite ID, if applicable)
This data is held only in memory on the server for the duration of the match and is discarded when the match ends. We do not write it to long-term storage.
Network metadata
Like any internet service, the connection between your browser and our game server exposes your IP address to the server for routing. The server logs basic diagnostic information (timestamps, error codes) but does not associate IPs with player identities.
Third parties
On sletter.io we use Plausible (cookie-less, privacy-respecting page-view analytics) and Google Analytics for aggregate traffic statistics. Neither service receives personal information from the game itself.
When you play Sletter.io on a third-party portal — for example CrazyGames, itch.io, or any other host — that portal may load its own scripts in the page (advertising, analytics, account features). Those scripts are governed by the portal's own privacy policy, not ours. Specifically, the CrazyGames SDK may show ads and collect telemetry per CrazyGames' privacy policy.
What we do not collect
- Email addresses, real names, or postal addresses
- Precise location data
- Device fingerprints
- Identifying cookies (we use localStorage only)
- Payment information (the game is free)
Children
Sletter.io is rated PEGI 12. It is not directed at children under 13. We do not knowingly collect personal information from children under 13.
Your rights
Because we don't store identifiable personal data on our servers, there's very little for us to access, correct, or delete on your behalf. You can reset everything we store on your device by clearing site data in your browser. If you have a specific concern, you can reach us at the address below.
Changes
If we change how the game collects or uses data, we will update this page and bump the date at the top.
