Local core play
The Android game is designed so core play and local progression do not depend on a mandatory user account.
Privacy boundary
No account does not mean
No account does not mean
no disclosure.
Sudoku Cosmos is designed around local core play, but accurate privacy communication must distinguish the Android product, optional rewarded advertising, the website, and any future store or measurement systems.
LOCAL×TRANSPARENT
Clear optional systems
Optional rewarded advertising, store delivery, support, and any later measurement must be disclosed according to the services actually present.
One truthful record
Website privacy information, app privacy policy, Play Data safety disclosures, SDK behaviour, and in-product settings must match.
Current website scope
This static website does not create user accounts, sell passes, or collect a game profile.
The site is a public brand, learning, and browser-sample surface. Before production analytics, newsletter capture, a public Play link, or an annual pass checkout are added, the privacy policy and consent experience must be updated to reflect the actual behaviour.
For the Android product, third-party SDKs such as advertising or crash reporting—if enabled in a given build—must be declared accurately in the Play console and the app privacy policy. This page is a product-design statement, not a substitute for final legal text.
Pre-launch wishlist
Launch updates are optional.
The wishlist stores an email address, consent time, and the page where the form was submitted inside this WordPress site. It does not create a game account, and it does not collect player-board data, browser fingerprints, or IP addresses for this form. The site owner can export those consented registrations only to prepare a launch update.
