Privacy Policy

Last updated: January 1, 2026

Plain-English Summary

Rack is privacy-first. Your workout data syncs between your Garmin and your iPhone — it never leaves your device without your permission. We don't build ad profiles. We don't sell your data. We don't share it with third parties. If you delete your account, everything goes with it.

What Rack never collects

  • Your real name (optional, never required)
  • Your precise GPS location
  • Your phone contacts
  • Advertising identifiers (IDFA)
  • Any third-party analytics or ad SDKs
  • Your data for sale to any third party
  • Biometric data for any purpose other than your own PRs

1. Information We Collect

We collect only the minimum information necessary to provide the Rack service. This includes: - Account information: email address (for account creation and login only) - Workout data: exercise name, sets, reps, weight, and timestamps — stored locally on your device and optionally synced to our servers for backup - Garmin data: heart rate, HRV, and activity data from your connected Garmin watch — processed locally and never transmitted to third parties - Device information: iOS version, app version, and crash logs for debugging purposes

2. How We Use Your Information

We use your information solely to: - Provide and improve the Rack app and services - Authenticate you and maintain your account - Generate Verified PR certificates - Send you transactional emails (receipt, account notifications) We do not use your information for advertising or sell it to any third party.

3. Data Storage and Security

Your workout data is stored primarily on your device. Optional cloud backup uses end-to-end encryption in transit (TLS 1.3) and at rest (AES-256). We store data on servers in the United States operated by Fly.io.

4. Data Retention and Deletion

You can delete your account at any time from the app settings. Upon deletion, all your data — workout history, PR records, and profile information — is permanently removed from our servers within 30 days.

5. Third-Party Services

Rack integrates with: - Garmin Connect IQ (on-device only, no data shared with Garmin beyond what their SDK requires) - Apple App Store (for purchase verification) - Fly.io (server infrastructure) We do not use Google Analytics, Facebook Pixel, or any advertising networks.
