Privacy Policy
Effective date: 2026-08-31
1. Scope
This policy applies to wound7.com and the "Wound7 Wound Tracker" mobile application (together, "the Service"), operated by an individual developer (Hao-Chih Tai, Taiwan).
2. What we do NOT collect (core app design)
- No account system: no registration; no names, emails, or identity data collected.
- No server: your cases, wound photos, symptoms and treatment records are stored only on your device (encrypted database); we cannot access them.
- Photos never uploaded: photos remain on the device; exports automatically strip EXIF/GPS/device metadata.
- No ads, no tracking SDKs.
3. Data we process
| Data | Location | Purpose |
|---|---|---|
| Cases / wounds / photos / records | Device only (SQLCipher encrypted) | Your own wound tracking |
| Language & preferences | Device only | Interface preferences |
| Purchase receipts | Apple / Google store systems | Pro entitlement (per store policies; we never handle payment data) |
| Website visits | GitHub Pages host logs | Basic traffic stats (no cookies, no analytics) |
4. Sharing & export
Data leaves your device only when you actively export it — as an encrypted package (.woundpkg, AES-256) or a plain viewing package (ZIP) — via channels you choose (AirDrop, messaging apps, etc.). Exports use anonymous codes (UUID) and contain no names or identity information.
5. Children's privacy
The Service is not directed at children under 13, and because there are no accounts we never learn any user's age or identity.
6. Data deletion
All data lives on your device: delete items in the app (cases/photos/records) or uninstall the app to remove everything. Since we hold none of your data, no deletion request to us is needed.
7. Changes & contact
Updates will be posted on this page with a new effective date. Privacy questions: contact@wound7.com
