Privacy Policy
Last updated: August 27, 2026
This policy covers this website, upside.com.pl. Each application published by UPSIDE Dariusz Majewski has its own privacy policy, because what each one handles differs:
- Undercell — the pentomino logic puzzle for Android and web browsers.
- AI Santa — the personalized Santa video generator.
Data we collect
None. This website collects no personal data. There is nothing to sign in to, no forms, no analytics, and no tracking or advertising cookies. We keep no logs that identify you.
Third-party content
None. Every asset this site uses — styles, icons and typefaces — is served from upside.com.pl itself. Your browser contacts no other party while you read these pages, so no one else sees your IP address through us.
Changes to this policy
Any change is published on this page with a new date above.
