About iCloud (iCloud Sync)
If you are signed in to iCloud, this app's records and photos are synced to your own account on iCloud (CloudKit) provided by Apple, in preparation for device changes and backups. This data is tied to your Apple ID and cannot be accessed by ychof. The handling of information stored in iCloud is governed byApple's Privacy Policy. If you do not wish to sync to iCloud, you can turn it off in your device settings.
About Photos
When attaching a photo to a record, this app may request access to your photo library or camera. The photos you select or take are saved as part of the record on your device (and your iCloud), and are never transmitted externally.

The backup feature exports and imports your records and photos as a file through your own actions. The storage location and sharing of the exported file are under your own control and are never transmitted to or stored on ychof's servers.
Contact Form
Only when you use the in-app contact feature are the message you enter, the email address you optionally provide, and the technical information needed to investigate issues (OS version and app version) sent to the developer. This happens only when you perform the send action and is never collected automatically.
Usage Data and Crash Reports
To improve the app's quality, this app uses Google's Firebase Analytics and Firebase Crashlytics. These services anonymously collect how the app is used (for example, screens viewed, app launches, and session information), crash and performance diagnostics (such as stack traces, device model, OS version, and app version), and an app instance identifier. The records, photos, and notes you create are never included.
This information is not linked to your identity, is not used for advertising or tracking, and the advertising identifier (IDFA / Advertising ID) is not collected. You can turn this off at any time under Settings > Privacy > "Send usage and crash reports".
