HazeLog (the "app") is designed with privacy first. The app collects no personal information and no usage data whatsoever.
None. The app does not collect or transmit any personal information, including your name, email address, contacts, location or device identifiers. No account is required.
Everything you enter — green beans, roast batches, temperatures, events and tasting notes — is stored only on your device. Neither the developer nor any third party can access it. The app makes no network requests and works fully in airplane mode.
No analytics SDK, no advertising SDK and no crash-reporting SDK are used. There is no tracking.
Since no data is collected, nothing is shared or sold.
You can export your records as CSV or PDF yourself; the destination is chosen by you in the system share sheet, and the app never uploads anything. Deleting the app deletes the records stored on your device.
The HazeLog Pro purchase is handled entirely by Apple's App Store. The app never receives your payment details. See Apple's privacy policy for how purchases are handled.
The app is suitable for all ages and collects no personal information from anyone.
