This policy explains what information Equacross (“Equacross,” “we,” “us”) collects when you use the Equacross website at equacross.com and the Equacross apps, and how it’s used.
Summary
- There are no accounts, no ads and no analytics or tracking.
- Games against the computer, pass and play, and puzzles stay on your device.
- Online games store the name you enter and the game itself on our server so both players can play.
- We don’t sell your information or share it for advertising.
Information stored on your device
Equacross saves your current game, your daily puzzle results and your settings in your browser’s or device’s local storage, so you can pick up where you left off. This information stays on your device and isn’t sent to us, except for online games as described below.
Online games
When you start or join an online game, we store on our server:
- The name you enter, up to 24 characters. You don’t have to use your real name.
- The game: the board, each player’s tiles, scores, the list of moves, and the 6-character game code.
- A scrambled (hashed) version of a random player key. The key itself is created on our server and saved on your device so you can rejoin your game. We keep only the scrambled version, which can’t be turned back into the key.
The other player in your game can see the name you entered, the board, the scores and the moves. They can’t see your tiles.
Service providers
Like any website, the services that deliver Equacross receive standard technical information, such as your IP address, browser type and the time of each request, and may keep it in their logs. We use:
- Supabase, which hosts our server and database for online games.
- GitHub Pages, which hosts this website.
- jsDelivr, which delivers a code library used for live online game updates.
These providers process information under their own privacy policies. We don’t use them to track you.
How we use information
- To run online games: dealing tiles, checking moves, keeping scores, and telling each player when it’s their turn.
- To keep games fair, for example by rejecting moves from someone who isn’t in the game.
- To fix problems and keep the service working.
- To answer you when you contact us.
We may also disclose information if the law requires it.
How long we keep it
We keep online game records so players can return to their games. We may delete old or inactive games at any time. If you email us, we keep your message and our reply for as long as we need them to help you.
Children
Equacross is a general audience game. We don’t ask for anyone’s age, and the only personal information online play asks for is a name, which can be a nickname. We don’t knowingly collect personal information from children under 13. If you’re a parent or guardian and think your child has given us personal information, email us and we’ll delete it.
Your choices
- You can play every mode except online without sending us any information.
- You can remove everything stored on your device by clearing your browser’s or device’s data for Equacross.
- You can ask us to delete an online game by emailing us with its game code.
Changes to this policy
If we change how Equacross handles information, we’ll update this page and the date at the top.
