Privacy Policy

Last updated: February 16, 2026

Kitae ("we", "our", or "the app") is a fitness tracking application for iOS. This Privacy Policy explains what data we collect, how we use it, and your rights regarding your information.

1. Data We Collect

Account Information

  • Email address and password — when you create an account with email and password
  • Apple Sign In data — when you sign in with Apple, we receive your identity token and optionally your name
  • First name and username — optionally provided during profile setup

Workout & Fitness Data

  • Gym workouts — exercises, sets, reps, weights, duration, and notes
  • Cardio sessions — activity type, distance, duration, pace, elevation, and splits
  • Templates — custom workout templates you create
  • Custom exercises — exercises you define
  • Personal records — tracked automatically from your workout history

Location Data

  • GPS coordinates — collected during outdoor cardio activities (running, walking, cycling) to track your route, including latitude, longitude, altitude, speed, and heading
  • Location is collected in the background while a cardio session is active so your route is tracked even when the app is not in the foreground
  • Location is only collected during active cardio sessions

Health & Motion Data

With your explicit permission, we access:

  • Apple HealthKit — heart rate, step count, active energy burned, distance, and workout data. Workouts are also written back to Apple Health for your records.
  • Motion & pedometer data — step count and cadence during cardio activities

HealthKit data is synced directly with Apple Health on your device. We store a HealthKit identifier to prevent duplicate entries but do not send your HealthKit data to our servers.

Preferences & Settings

  • Weight and distance unit preferences, rest timer settings, theme preference, and other app settings

2. How We Use Your Data

  • Provide the service — store and sync your workouts, templates, and progress across devices
  • Track your fitness progress — calculate analytics, personal records, and trends
  • Display route maps — show GPS routes for your cardio sessions
  • Sync with Apple Health — write completed workouts to HealthKit with your permission
  • Offline functionality — cache data locally so you can use the app without an internet connection

We do not use your data for advertising, profiling, or any purpose unrelated to providing the fitness tracking service.

3. Third-Party Services

Clerk (Authentication)

We use Clerk to handle account authentication. Clerk receives your email address (for email/password sign-in) or Apple identity token (for Apple Sign In) and manages session tokens. Clerk does not receive your fitness data.

Convex (Backend Database)

We use Convex to store and sync your data. Your workouts, templates, profile, and preferences are stored on Convex servers. All data is transmitted over encrypted HTTPS connections and authenticated with secure tokens.

No Analytics or Tracking

We do not use any third-party analytics, crash reporting, or advertising services. There are no trackers in the app.

4. Data Storage & Security

  • In transit — all data is transmitted over HTTPS/TLS encrypted connections
  • At rest (server) — stored securely on Convex infrastructure
  • At rest (device) — cached locally in your app sandbox, protected by iOS device encryption
  • Passwords — handled entirely by Clerk and never stored by us

5. Data Sharing

We do not sell, rent, or share your personal data with third parties for marketing or advertising purposes. Your data is only shared with the service providers listed above (Clerk and Convex) as necessary to operate the app.

6. Your Rights & Data Control

  • Delete your account — you can permanently delete your account and all associated data from Settings → Account → Delete Account. This removes all your workouts, templates, exercises, profile data, and preferences from our servers.
  • Delete individual data — you can delete individual workouts, templates, and custom exercises at any time
  • Edit your profile — you can update your name and username at any time
  • Revoke permissions — you can revoke HealthKit, Location, and Notification permissions at any time through iOS Settings

7. Data Retention

We retain your data for as long as your account is active. When you delete your account, all data is permanently removed from our servers. Local cached data is removed when you uninstall the app.

8. Children's Privacy

Kitae is not directed at children under 13. We do not knowingly collect data from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes through the app or by updating the date at the top of this page.
