The already-released apps below are governed by their own Privacy Policy, and are not covered here.
This Policy sets out how user information is handled in any application ("the App" / "the Apps") newly provided by Yuto Sasaki ("we" or "us") after this Policy is posted.
Data you create, such as notes and records, is stored only on your device as a rule. Where a feature such as cloud sync is offered, its storage location and handling are stated within the relevant App. Our servers do not access the contents you create.
The body text or photos of notes and records you create are never included.
Collected information is used only to provide and improve the Apps, fix issues, and perform statistical analysis.
The Apps may use external services for analytics, billing management, cloud sync, and the like. The services used differ by App, and each service's privacy policy applies. The main services used are stated within each App.
Except as required by law, we do not provide collected information to third parties.
For Apps that display ads or obtain advertising identifiers, this is stated individually within each App and on this page. Apps without such a statement do not display ads or obtain advertising identifiers.
Access to device features such as the camera and photo library occurs only when you use the relevant feature, based on your OS permission settings.
Data on your device is deleted when you uninstall the App. Where an App has a delete feature, its behavior follows that feature.
This Policy may be changed as needed. Changes take effect when posted on this page.
For questions about this Policy, please use the contact form.
