This policy describes how the Darkroom Companion app handles data. The app is designed with your privacy in mind and in line with the GDPR and CCPA — it collects no personal data and works fully offline, without an account.
2. Data processing and storage
The app does not collect or transmit any personal data. The data you create — your own recipes, chemical inventory, development history, and settings — is stored solely locally on your device, and the developer has no access to it. Your data may be backed up automatically by your operating system (iCloud on Apple, Google backup on Android) if you have it enabled; such backups are managed by Apple or Google under their own terms, not by this app.
3. Permissions and no tracking
The app contains no analytics, advertising, or tracking technologies and requires no internet access to function. The backup feature (export and import) uses the system share sheet or file picker only on your explicit action; without your instruction the app does not access your files.
4. Your rights (GDPR and CCPA)
No data sale: we collect no data and sell none.
Access and control: all your data stays on your device and is accessible anytime directly in the app.
Erasure: remove your data directly in the app, or by uninstalling the app entirely.
