Decussis
Privacy policy
Last updated: September 5, 2026
The short version
Decussis works offline and needs no account of its own. Your progress is stored on your device. Data leaves your device only when advertising is displayed, when you choose to sign in to Google Play Games, and when you make a purchase.
Data stored on your device
Your progress (levels, statistics, and settings) is saved locally on your device. It is not transmitted anywhere unless you sign in to Google Play Games. Uninstalling Decussis deletes it.
Advertising
Decussis displays advertising through Google AdMob. To do so, AdMob may process:
- your device's advertising identifier (Advertising ID)
- device information such as model, operating system version and language
- approximate location derived from your IP address
- your interactions with the ads shown in the app
If you are in the European Economic Area, the United Kingdom or Switzerland, you are asked for consent before personalised advertising is used. You can change that choice at any time under Settings → Ad privacy settings in the app.
Google's handling of this data is described at https://policies.google.com/technologies/partner-sites.
Removing ads through a purchase stops advertising and the associated data processing entirely.
Google Play Games Services
Signing in to Google Play Games is optional and off by default. If you sign in:
- your Play Games player ID and public profile name are used to show leaderboards and achievements
- your progress is stored in Google's Saved Games service so it can move between your devices
You can sign out at any time in the app's settings. Google's handling of this data is covered by the Google Privacy Policy at https://policies.google.com/privacy.
Purchases
Purchases are processed by Google Play Billing. Decussis never sees or stores your payment details; it only records whether a purchase is active.
Children
Decussis is suitable for all ages and does not knowingly collect personal data from children. It has no chat, no user-generated content and no social features beyond Google's own leaderboards.
Your rights
Under the GDPR you may request access to, correction of, or deletion of personal data relating to you, and you may object to its processing. Because the app itself stores everything locally, most such requests concern Google as the provider of the services named above.
To delete all local data, uninstall the app. To delete cloud-saved progress, remove the game from your Google Play Games profile. For anything else, contact yannick@sequencode.dev.
Changes
If this policy changes, the updated version will be published at this address with a new date at the top.
