SmartCat Privacy Policy – Catfish Chess

Last updated: 20 September 2026

In short

Catfish Chess is made for families. The game contains no advertisements and no in-app purchases. Signing in to Google Play Games is optional – the whole game can be played without signing in, and without any data being sent to Google Play Games.

We do not sell your data, and we do not share it with anyone for advertising.

What the game stores on your device

• Your chess rating for each game style, the number of games played, and which levels you have unlocked.
• The nickname you choose.
• An identifier and a password that the game generates at random. These are not connected to your name, your email address or your Google account. They only allow our server to recognise the same installation again.

What is sent to SmartCat's server

When your device is online, the game sends your rating, the number of games played and your chosen nickname to our server at smartcat.fi. This is used to show the game's own high score list and to keep the chess engine's ratings up to date.

Your nickname and rating are visible to other players on that list. Please do not use your real name, and do not enter any personal information as a nickname.

What is sent to Google Play Games

This happens only if you choose to sign in to Google Play Games. If you do:

• Leaderboards. Your score and your Play Games display name become visible to other players on the public leaderboard for that game style.
• Achievements. Achievements you unlock are stored in your Play Games profile.
• Cloud save. Your game progress – the same information listed above, including the identifier and password that the game generated – is stored in your own Google Drive, in a private folder reserved for this game. This is what allows your progress to move to a new device.

Google processes this data under its own privacy policy: https://policies.google.com/privacy

If you never sign in, none of the above is sent to Google Play Games.

Children

Catfish Chess takes part in Google Play's Designed for Families programme, and we are committed to complying with the Google Play Families Policies.

We do not knowingly collect any personal information about children beyond what is described on this page. There are no advertisements in the game, and no data is shared for advertising.

Signing in to Google Play Games requires a Google account. Parents can decide whether a child signs in – the game is fully playable without it, and nothing is sent to Google Play Games unless the player signs in.

How to remove your data

• Play Games data (leaderboard entries, achievements and the cloud save) can be deleted through the Google Play Games app or through your Google account settings.
• Data on our server can be removed by emailing pete@smartcat.fi. Please mention the nickname you used so we can find the right entry.
• Data on your device is removed when you uninstall the game or clear its data in your device settings.

Changes to this policy

If this policy changes, the date at the top of this page will be updated.
