Momentum privacy policy

Information we collect

Account. Your name, email address, handle, and password (stored as a cryptographic hash), plus an optional profile photo and status message.

Activity. The training sessions you log (activity, duration, training partners), and things derived from them: streaks, check-ins, personal-record entries, self-commitments (including the friend you optionally pick as a witness), and challenge scores and results.

Media. Photos and videos you choose to attach: profile photos, feed posts, and PR or challenge proof clips. Proof clips are reviewed to verify the result.

Your crew. Friend requests, accepted friends, blocks, and the nudges and cheers you send.

Health data. Only if you connect Apple Health or Health Connect; covered in its own section below.

Waitlist and support. If you join the waitlist or contact support, we keep what you submit so we can respond.

We do not collect your location, contacts, or browsing history, and the app contains no advertising or third-party analytics SDKs.

Health data (Apple Health and Health Connect)

Connecting a health hub is optional: nothing is read until you connect it in the app and grant permission in iOS or Android.

Read-only. Momentum reads two things: your daily step count and recent workouts. It never writes anything to Apple Health or Health Connect, and it only reads while the app is open — never in the background.

Processed on your phone by default. Steps and detected workouts are used on your device to show your daily movement and to suggest logging a workout. By default, this raw health data is not uploaded to or stored on our servers. If you tap "Log it" on a suggestion, a normal activity log (the activity and its duration) is saved to your account, exactly as if you had logged it by hand.

Steps leaderboard (optional, opt-in). If you turn on "Share my steps with my crew," your daily step totals are uploaded to our servers so they can appear on a steps leaderboard visible only to your accepted friends. This is off by default, nothing else from Apple Health or Health Connect is uploaded, and turning it off removes your stored step history from our servers.

Never for advertising. Health data is never used for advertising or marketing, never sold, and never shared with third parties. Step totals shared to the leaderboard are visible only to your crew.

Disconnect anytime. In the app under Settings, or in iOS Settings → Privacy & Security → Health → Momentum, or in the Health Connect app on Android.

How we use information

To run Momentum: showing your training to your crew, computing streaks and leaderboards, running challenges and commitments, sending the notifications you've enabled (nudges, witness alerts, reminders), verifying PR proofs, responding to support, protecting the service from abuse, and understanding what to build next. Nothing else.

What others can see

Your activity, streaks, PRs, and commitments are visible only to friends you've accepted. Leaderboards are private to your crew. Nothing about you is public. Share cards (for example, a completed commitment) leave the app only when you export one yourself.

Service providers

We use a small set of providers to run Momentum: application hosting (Railway), media storage (Supabase), and push-notification delivery (Expo, Apple, Google). They process data only to provide the service.

Retention and deletion

We keep your data while your account is active. To delete your account and everything in it (logs, media, commitments, and challenge history), email hello@liftwithmomentum.com from your account email and we'll remove it from our production systems within 30 days.

Changes

If this policy changes, we'll update this page and the date at the top.
