Privacy Policy

Last updated: January 2025

1. What data we collect

Skintrics is designed to keep your health data private. Here is exactly what we collect and don't collect:

• We do not collect your skin logs, severity ratings, exposure entries, notes or any health data you enter into the app. This data is stored locally on your device only.
• We do not collect your name, email address or any personally identifiable information.
• Sign in with Apple provides us with a unique anonymous identifier only. We do not receive your Apple ID email address unless you explicitly choose to share it.
• Weather data — if you grant location permission, we request current weather data from OpenWeatherMap using your approximate location. We do not store or log your location.
• We do not use analytics, advertising SDKs or any third-party tracking tools.

2. Where your data is stored

All data you enter into Skintrics — your skin logs, exposures, notes, severity ratings and GP export data — is stored exclusively on your iPhone using Apple's SwiftData framework.

This data does not leave your device. It is not backed up to our servers, transmitted to third parties or accessible to us in any way.

If you enable iCloud backup on your device, Apple may back up this data as part of your standard iCloud app backup. This is governed by Apple's privacy policy, not ours.

3. Data deletion

If you delete your Skintrics account from within the app, all locally stored data is permanently deleted from your device. This action cannot be undone and your data cannot be recovered.

If you delete the app from your iPhone, all associated data is also deleted.

4. Third-party services

Skintrics uses the following third-party services:

• Sign in with Apple (Apple Inc.) — for authentication. Apple's privacy policy applies to this service.
• OpenWeatherMap — for current weather data in the log screen. Only your approximate location is sent to retrieve weather. No personal data is transmitted.
• Apple StoreKit — for managing Premium subscriptions. Payment processing is handled entirely by Apple.

5. Children's privacy

Skintrics is not directed at children under the age of 13. We do not knowingly collect any information from children.

6. Changes to this policy

If we make material changes to this privacy policy, we will update the date at the top of this page. Continued use of the app after any changes constitutes acceptance of the updated policy.
