While playing Solve the Wall, no data is retrieved, stored, or retained other than what Meta automatically collects. All app data (such as settings, progress, and preferences) is stored locally on the device and is never seen by the Solve the Wall team or developers. Contact john@solvethewall.com for any questions or requests regarding data removal**.
**App Lab submissions require we provide a contact for data removal requests. However, in this case there would be no data to remove since nothing is collected outside the device.
