🧪 Gravity Lab — Privacy Policy

Effective date: June 12, 2026

The short version for parents: Gravity Lab collects nothing. No ads, no tracking, no analytics, no accounts, no internet features. Everything your child does in the app stays on the device.

What data we collect

None. Gravity Lab does not collect, store, transmit, or share any personal information or usage data. The app:

Has no advertising and no third-party SDKs of any kind.
Has no analytics or tracking.
Requires no account, login, or sign-up.
Makes no network connections — it works fully offline.
Contains no in-app purchases — coins and marble skins are earned only by playing.
Has no external links, no social features, and no free-text input.

Game progress

Stars, coins, badges and the daily streak are saved only in the app's local storage on your device. Deleting the app permanently deletes this data. It never leaves the device.

Motion sensor

Gravity Lab reads the device's tilt (accelerometer/gyroscope) in real time to steer the marble — that is the whole point of the game! Tilt readings are used instantly to move the marble and are never recorded, stored, or transmitted.

Children's privacy (COPPA)

Gravity Lab is designed for kids aged 8–12 and complies with the Children's Online Privacy Protection Act (COPPA) and the App Store Kids Category guidelines by the simplest possible means: it collects no data from anyone, of any age.

Changes to this policy

If a future version of the app ever changes this (for example, an optional parent dashboard), this policy will be updated first and the change will be clearly disclosed in the App Store notes.
