Overview
UHP.x is developed by Dr. Mohammed Fasil. This Privacy Policy explains what data the app collects, how it is used, and your rights regarding that data. We take your privacy seriously and have built UHP.x with a minimal-data approach.
Data We Collect
UHP.x collects only the information you explicitly provide within the app:
- Profile information — your name, salutation, and institution, entered during onboarding or in Settings. Stored locally on your device only.
- Mix design data — inputs, results, material libraries, casting dates, and test results you create. All stored locally on your device.
- App preferences — settings and display preferences, stored locally via iOS UserDefaults.
UHP.x does not transmit any personal data to external servers. All data remains on your device at all times.
Data We Do Not Collect
- No analytics or usage tracking
- No crash reporting sent to third parties
- No advertising identifiers
- No location data
- No contacts or camera access
- No account registration required
Data Storage
All data created in UHP.x is stored locally on your iPhone or iPad using standard iOS storage (UserDefaults and app sandbox). Data is included in your device's iCloud backup if you have iCloud Backup enabled — this is controlled entirely by your iOS settings, not by UHP.x.
PDF Export
When you export a mix design as a PDF, the file is generated entirely on your device. You choose where to send or save it. UHP.x does not have access to any exported files after they leave the app.
Reminders
If you add curing reminders, UHP.x requests access to your Apple Reminders app. This access is used solely to create reminder entries on your device. No reminder data is transmitted anywhere.
Data Deletion
You can delete all app data at any time from Settings → Data → Clear All within the app. Deleting the app from your device removes all locally stored data permanently.
Children's Privacy
UHP.x is intended for professional and research use by adults. The app does not knowingly collect data from children under 13.
Changes to This Policy
If this policy changes materially, we will update the date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
