Privacy Policy

1. Summary

• No account registration or login is required.
• No personally identifiable information (PII) is collected by DerryTech.
• No access to location, contacts, camera, or microphone.
• No advertising or sale of personal data.
• Anonymous usage analytics via TelemetryDeck help improve the app.
• Your collection data is stored locally and optionally synced to your personal iCloud account.

2. Data Collection

Kyber Tracker does not require an account and does not collect names, email addresses, or other personally identifiable information. Crystal entries you create (notes, locations, quantities, and related metadata) remain on your device unless you enable iCloud sync.

3. Analytics (TelemetryDeck)

Kyber Tracker uses TelemetryDeck to understand how features are used so we can improve the app. Analytics signals may include:

• Screen or feature names (for example, which tab was opened)
• Anonymous action events (for example, crystal added, edited, or moved)
• Non-identifying crystal attributes such as color, order, series, or rarity
• Stable error codes for diagnostics (no free-form error messages or file paths)

Analytics data does not include your notes, locations, purchase dates, or other free-text content. TelemetryDeck is designed for privacy-friendly analytics without invasive tracking or cross-app profiling.

4. iCloud Sync (Premium)

If you enable iCloud sync, your app data is stored in your personal Apple iCloud account. DerryTech does not access, transmit, or control this data. iCloud usage is governed by Apple’s terms and privacy policies. You can disable iCloud sync in the app settings or in your device’s iCloud settings at any time.

5. Local Storage

All data is stored locally on your device using Apple’s SwiftData framework unless iCloud sync is enabled. Deleting the app removes local data unless it has been synced to iCloud or exported by you.

6. Export & Import

You can export your collection and wishlist as JSON at any time from Settings. Importing data is performed entirely on your device. Exported files are under your control — we do not receive them.

7. In-App Purchases

Premium purchases are processed by Apple through the App Store. DerryTech does not receive your payment card details. Apple may provide us with purchase status information necessary to unlock Premium features.

8. Children’s Privacy

Kyber Tracker does not knowingly collect personal information from children under 13. The app is suitable for general audiences but is not specifically directed at children.

9. Your Control

Because we do not collect personal information, there is no account profile to delete on our servers. You control your data on your device and in your iCloud account. You can export, delete, or disable sync at any time from within the app.

10. Changes to This Policy

We may update this policy if our data handling practices change. Updates will be posted on this page with a revised “Last updated” date and made available within the app where applicable.
