Privacy Policy／隱私權政策

Effective date: September 6, 2026

串門運動 ("the app") is developed and published by the developer listed on our App Store page. This policy explains what information the app handles and how.

No account, no server, local only

The app requires no account and no sign-in, and it has no server. Everything you enter — nicknames, birth years, measurement results, exercise history, settings — is stored only on your device, protected by iOS data protection. Nothing is uploaded. Deleting a person card, or "Delete all data" in Settings, removes it permanently. Standard iOS device backups may include the app's data; that backup is controlled by you and Apple.

Sharing between phones

When you send a person card to a friend, the data travels directly from your phone to theirs as a QR code, or as a link whose content sits in the URL fragment. The fragment is never sent to this website's server, and this website does not log or store card contents.

Camera

The camera is used only to scan a friend's QR code and, optionally, to measure a 3-metre distance on the floor. No photos or video are stored or transmitted.

Notifications

If you allow notifications, the app schedules a daily reminder and a 12-week re-measurement reminder locally on your device. No push server is involved.

Advertising and analytics

The app contains no advertising, no in-app purchases, and no analytics or tracking SDKs of any kind.

Health-related information

The app records physical-performance test results and an exercise level. This information is not a medical diagnosis, is not shared with anyone, and is used only to choose which exercises the app shows. Please consult a doctor for any health concern.

Children

The app is intended for older adults and their friends and family, is rated 4+, and does not knowingly collect personal information from children.

Changes & contact

If this policy changes, the updated version will be posted on this page with a new effective date. Questions? Email wuyuping38@gmail.com.
