Gripp Privacy Policy

Last updated: March 22, 2026

Gripp is a training and community app for grip and hanging practice. This Privacy Policy explains what data the app currently uses based on the app's implemented features.

Information We Collect

We collect information you provide directly in the app, including:

- Account information such as your email address if you sign in by email.

- Authentication information from Apple if you choose Sign in with Apple. On first sign-in, Apple may also provide your name and email address.

- Profile information such as username, first name, year of birth, gender, weight, unit preferences, baseline settings, timezone, and whether your profile is private.

- Training and progress data such as workout attempts, challenge attempts, training routine sessions, personal bests, measurements, streak/progress-related records, and equipment preferences.

- Gripp Social data such as follows, likes and in-app notifications.

- Images you choose to upload for your profile.

- Push notification data if you enable notifications, including your Expo push token, device type, device name, timezone, and notification preference settings.

The app also stores some data locally on your device, including your signed-in session and certain app preferences.

How We Use Information

We use this information to:

- create and secure your account;

- run core app features;

- save your profile, workouts, progress, measurements, and community activity;

- deliver push notifications if you enable them;

- show community features such as profiles, likes, follows, and leaderboards;

- understand how the app is used and improve it.

If your profile is public, other users may be able to see information connected to your public profile and activity in the app. If your profile is private, the app is designed to restrict visibility of private-profile activity to other users.

Analytics

Gripp uses PostHog for product analytics. PostHog is used for screen views, app lifecycle events, taps/interactions, and product events such as sign-in, onboarding, training, group, challenge, and settings actions.

The app also sends a small set of profile properties to PostHog to help understand product usage, including year of birth, gender, baseline, weight unit, and weekly goal. The current code specifically avoids sending email address, first name, and username to PostHog as person properties.

Third-Party Services

Gripp currently relies on these third-party services:

- Supabase: used for authentication, database storage, file storage, and backend functions. Supabase Privacy Policy

- PostHog: used for analytics and product usage tracking. PostHog Privacy Policy

- Expo Notifications: used to obtain and deliver push notifications when you enable them. Expo Privacy Policy

- Sign in with Apple: used only if you choose Apple sign-in. Apple Privacy Policy

Photos and Permissions

The app requests access to your photo library only if you choose to upload a profile image or a group image.

The current app code does not appear to request precise location, contacts, or camera access for core app functionality.

Data Sharing

We do not sell your personal information.

We share data with service providers only as needed to run the app:

- Supabase stores account, app, and uploaded file data.

- PostHog receives analytics data.

- Expo processes push notification delivery data when notifications are enabled.

- Apple is involved only if you use Sign in with Apple.

Children's Privacy

Gripp is not directed to children under 13, and we do not knowingly collect personal information from children.

Your Choices

You can:

- keep your profile private or public;

- disable push notifications in the app or in your device settings;

- remove uploaded profile photos;

- delete your account from the app's account settings.
