Privacy policy

Last updated: 14 September 2026

RotaBall is published by STNC. This policy describes how we handle information for the RotaBall mobile apps, the browser demo on rotaball.stnc.com, and this website.

Summary

  • The puzzle itself has no accounts, no ads, and no third-party tracking.
  • Progress and settings are stored on your device (or in your browser’s local storage for the demo). We do not receive them.
  • The only data the apps send us is a Hall of Fame entry, and only when you choose to submit one: three initials, your score and time, and a proof that the score came from a genuine copy of the game.
  • On this site, the only personal data we collect is what you send through the contact form.

Game and demo data

When you play RotaBall on iOS, Android, or the web demo, the app or browser stores preferences (music, sound, colour marks), level progress, passwords, and your best times locally. That data stays on the device unless you clear the app data or browser storage. We do not receive it, and the web demo sends nothing to us at all.

Hall of Fame

The iOS and Android apps have an optional worldwide Hall of Fame. Nothing is sent unless you finish a run, choose to submit, and enter three initials. When you do, the app sends to our server at rotaball.stnc.com:

  • The initials you typed, your score, your total time, the number of levels cleared, the date, the platform (iOS or Android), and the app version.
  • A proof that the entry came from an unmodified copy of RotaBall: on iOS an Apple App Attest key and assertion, on Android a Google Play Integrity token. Apple or Google generate these on the device; they identify your installation of the game, not you, and contain no name, email, or Apple/Google account details.
  • A random key created for your installation of the game, stored in hashed form. It lets the app highlight your own rows when you view the table and lets us remove all of an installation’s entries on request. If attestation is unavailable on a device, the app falls back to the platform’s vendor or Android identifier, which on Android is hashed before it leaves the device.

We use this information only to display the Hall of Fame, to reject forged scores, and to limit abuse. Initials, score, time, levels, date, and platform are shown publicly in the table inside the app. When you open the Hall of Fame, the app also sends the hashed installation key so your own entries can be marked; it does not send your progress or settings.

Entries are kept for as long as the Hall of Fame runs. Our server records the requesting IP address for a short time to rate-limit submissions, and keeps a log of whether each proof was accepted, with the installation key and app version, so we can investigate cheating. Neither is shown publicly, and neither is sold, shared with third parties, or used for advertising. The proof itself is verified with Apple’s or Google’s services as part of how App Attest and Play Integrity work; their own policies apply to that step.

To remove your entries, email support@stnc.com with the initials, approximate date, and platform. If you delete the app, the installation key is deleted with it and any later install is treated as new.

Contact form

If you use the support form, we receive your name, email address, message, and the approximate technical details our host records with the request (such as IP address and time). We use this only to reply and to operate support. We do not sell it or use it for advertising.

Messages are delivered by email to STNC. Retention follows ordinary email practice; you may ask us to delete a conversation by writing to the same address.

Store links and hosting

This site is hosted for STNC. Standard web-server logs may record IP addresses and requested URLs for security and reliability. App Store and Google Play are separate services with their own policies when you download the apps.

Children

RotaBall is a puzzle suitable for ages 4+. The Hall of Fame asks for nothing beyond three initials, and we do not knowingly collect personal information from children except when a parent or guardian contacts us through the support form.

Your choices

To ask a question, have Hall of Fame entries removed, request deletion of a support email thread, or raise a privacy concern, use the support page or email support@stnc.com.

Changes

We may update this policy when the product or hosting changes. The date above will be revised.
