YOSUGA

Privacy Policy

Yosuga (the “App”) respects user privacy and handles information carefully. This Policy explains how information is handled in the App.


Basic Policy

The App values keeping users’ information in their own hands. It does not require account registration, does not operate an independent backend server, and does not use analytics tools or advertising networks to track user behavior.

Information Handled

The App stores information entered or saved by users primarily on the user’s device, including saved URLs, automatically retrieved titles and thumbnails, optional notes, promise-related management data, and paid-feature purchase status.

iCloud (CloudKit) Sync

If users enable iCloud, this information may sync between the user’s own devices through Apple iCloud (CloudKit private database). The operator cannot access the synced data.

Network Communication

Network communication is limited to retrieving public metadata, such as titles and thumbnails, from URLs saved by users. The App itself does not send those contents to an operator-run server.

Notifications

Notifications are generated locally on the device. No information is sent to a server for notifications, and notifications can be turned off in iOS settings.

Payment Information

Paid features are processed through Apple in-app purchase (StoreKit). The App only keeps purchase status on the device. Credit card numbers and other payment details are handled by Apple.

Third-Party Disclosure

The operator does not sell, lend, or provide user information to third parties, except where disclosure is required by law.

Data Deletion

Deleting the App from the device deletes App data stored on that device. Information synced to iCloud can be deleted through iOS or iCloud settings.

Children’s Privacy

The App does not intentionally collect personal information from any specific age group and, as described above, does not collect information that directly identifies individuals.

Changes to This Policy

The operator may update this Policy as needed. Updated content becomes effective when posted on this page.
