Privacy Policy for Quick Catch
Last updated: 20 May 2026
Quick Catch is developed and maintained by Harry Hasson Lynch as an independent developer. This policy explains what data Quick Catch collects, how it is used, and your rights as a user.
What data we collect
Training data
Session logs, splits, training zones, and plans are stored locally on your device using Apple's secure on-device storage. This data does not leave your device unless you choose to export it.
Account information
If you sign in with Apple or Google, Quick Catch stores your user ID, display name, and email address locally on your device to identify your account. This information is not transmitted to Quick Catch's servers.
Apple HealthKit
With your permission, Quick Catch reads and writes workout data to Apple Health. This data never leaves Apple's ecosystem and is governed by Apple's own privacy policy.
Analytics and usage data
Quick Catch collects anonymised usage analytics to understand how the app is used and to improve the training experience. This includes:
- Events such as screens viewed, features used, and subscription interactions
- A pseudonymous identifier linked to your account (if signed in) or a randomly generated device ID (if using as a guest)
- Basic device information (platform, app version)
Analytics data is collected via PostHog and is transmitted securely over HTTPS. No personally identifiable information (such as your name, email, or training content) is included in analytics events.
You can limit ad tracking in your device settings, which will also limit analytics identification.
AI plan generation
When you use the "Generate with AI" feature, your training preferences (training days, weekly volume, athlete type, heart rate range, and any optional notes) are sent to a secure processing endpoint to generate your plan. This data is processed in real time and is not stored, logged, or retained after your plan is returned.
What we do not collect
- Precise location data
- Advertising identifiers (IDFA)
- Contacts, photos, or media (except PM5 screen capture for workout import, processed on-device)
- Any data beyond what is described above

Children's privacy

Your rights
You may request deletion of your analytics data by contacting us at the address below. Training data stored on your device can be deleted at any time from Account → Profile → Delete Account, or by uninstalling the app. HealthKit data can be managed directly in the Apple Health app.
