Privacy
Your process is yours. ChemClock does not collect personal data.
On-Device Processing
All calculations, timer logic, and data storage are performed locally on your device using SwiftData. We have no servers, no backend, and no way to access your records. The app is designed to function completely offline.
No Third-Party Services
ChemClock does not integrate any third-party analytics, advertising, or tracking frameworks. The app makes no network requests. There is no authentication, no cloud sync, and no remote logging.
No Account Required
You don't need an account to use ChemClock. There's no email collection, no profile, and no sign-up. The concept of a user doesn't exist on our side because we have no side to store it.
Data Inventory
The following table lists every type of data the app touches:
| Data Type | Stored On Device | Sent to Server |
|---|---|---|
| Film/developer presets | Yes (SwiftData) | No |
| User-created sequences | Yes (SwiftData) | No |
| Timer history | Yes (SwiftData) | No |
| Crash reports | No | No |
| Usage statistics | No | No |
Data Deletion
Uninstalling the app removes all your data. Since nothing ever leaves the device, there is no server-side copy to delete.
