Sudoku Four privacy
What this app saves on your device and what it sends to AhmedSoftware.
Last updated: November 7, 2026
On your device
Sudoku Four saves your games, settings and history on your device. Removing the app removes this local data.
Usage data
Usage data is optional. It stays off until you choose Allow in the app, and you can turn it off at any time in Settings.
If you allow it, Sudoku Four sends a random installation ID, the app version, platform version, locale, device class and gameplay events. The events describe a puzzle or deal being opened, completed or shared.
It does not send your name, email address, contacts, location, advertising ID, hardware identifiers, board contents or per-move timing.
Raw events are kept for up to 90 days and then deleted. Installation records keep the app version, platform, locale, device class and last-seen time for aggregate counts. Turning the setting off stops future events; it does not remove events already received.
Requests from the app reach this website, so the standard hosting logs described on the site privacy page also apply.
Update checks
The app checks for updates at most once a day. The request includes the app name, version and platform, but no installation ID.
Ads
This app contains no ads.
Downloads and the website
APK downloads and the public website are covered by the site privacy page.
Data deletion
You can ask for the data AhmedSoftware holds about your use of Sudoku Four to be deleted. Send the request through the contact form, mention data deletion and include the app name.
If you allowed usage data, include the installation ID shown in the app's settings. It is the only way to match the stored events and installation record to you, so the record cannot be found without it.
If the app keeps an account or cloud saves, include the email address you use to sign in. Requests are answered at the email address you enter in the form.
Raw usage events are deleted automatically after 90 days. A deletion request removes the installation record and any remaining events sooner.
