Privacy Policy
Effective September 7, 2026
Gravelo is designed to be played without an account and without sending your activity to a Gravelo-operated server.
Data stored on your device
Gravelo stores your level progress, completion times, settings (sound, haptics, timer display, tilt calibration), and locally tracked achievement progress on your device using Apple platform storage. There is no backend server and no analytics or advertising SDK involved — this is the entire persistence layer. Removing the app also removes its local data, subject to the behavior of device backups managed by Apple.
Motion data
Gravelo uses your device's motion sensors (Core Motion) to read tilt and control the ball on screen. Motion readings are processed on device in real time to drive gameplay and are never recorded, stored, or transmitted anywhere.
Game Center
Gravelo can report achievements and a levels-completed leaderboard to Game Center. This is optional and best-effort: if you are signed out of Game Center or decline to authenticate, Gravelo simply keeps tracking your progress locally and nothing is sent. When you are signed in, Apple's Game Center handles that data under its own privacy policy — Gravelo does not receive your Game Center account details beyond what GameKit exposes for reporting scores and achievements.
Analytics, advertising, and tracking
The Gravelo app does not include advertising SDKs, third-party analytics SDKs, or cross-app tracking. Gravelo does not sell personal data.
When you install a beta through TestFlight, Apple may provide crash, session, installation, and tester-feedback information through App Store Connect. Apple controls that processing under its own terms and privacy policy.
Children
Gravelo does not collect personal information from any user, including children. There is no account creation, no chat, and no user-generated content shared with anyone.
Changes
This policy may be updated when Gravelo's data practices change. The effective date above identifies the current version.
