Data Collection & Analytics
Stored on your device
Your progress, unlocks, best runs and settings are stored only on your device (in the browser version, in your browser's local storage). They are never sent to us. Deleting the game, or clearing site data in your browser, deletes them.
Analytics
The game does not use Google Analytics, Firebase Analytics or any other analytics SDK.
Browser version
The browser version is served from tetherrunner.buidan.com. It shows no ads and loads no analytics or advertising scripts. Our web host may keep standard access logs (IP address, browser type, pages requested) for security and to keep the site running.
Third-Party SDK Disclosures
The game includes no third-party analytics, advertising or tracking SDKs.
Children's Privacy (COPPA)
The game is not directed at children under 13, and we do not knowingly collect personal information from children under 13, in line with the U.S. Children's Online Privacy Protection Act (COPPA) and similar laws. If you are a parent or guardian and believe your child has provided personal information through the game, email [email protected] and we will delete it.
Account & Data Deletion
The game has no accounts, so there is no account to delete. To delete your data:
- On your device: uninstall the app (or, in the browser, clear site data for tetherrunner.buidan.com). This removes everything the game stored.
Security
Information sent by the game travels over encrypted connections (HTTPS/TLS).
Changes
If this policy changes, we will update this page and the date at the top.
