Privacy Policy
Week Number is designed to work without an account or a remote service. We do not collect, sell, rent, or use personal data for advertising or tracking.
Information we collect
We do not collect personal information, usage analytics, diagnostics, advertising identifiers, location, contacts, photos, or browsing activity.
Information stored on your devices
Your selected week-numbering rule is saved locally using Apple system storage. The app and its widgets share that setting on the same device. A paired Apple Watch may receive the same setting directly through Apple’s Watch connectivity system. Wenlin Fan does not receive this information.
Sharing a week
If you choose Share Week, Apple’s system share sheet sends the text only to the service or person you select. Any third-party service you choose is governed by its own privacy policy. Week Number does not receive a copy.
Third-party services
Week Number includes no advertising, analytics, tracking SDKs, or developer-operated backend service.
Children’s privacy
Because no personal data is collected, the app does not knowingly collect personal information from children.
Changes to this policy
If the app’s data practices change, this page and the App Store privacy disclosure will be updated before the change takes effect.
