Privacy

On your device

Dayline stores your class names, room locations, timetable and selected time zone locally. The native iOS app does not transmit this information to the developer and works without an account or internet connection. The web app stores your changes in this browser’s local storage.

No tracking

Dayline includes no advertising, analytics SDKs or tracking. Room locations are text that you enter. Dayline does not request or access your GPS location.

Your choices

You can edit your schedule, restore the starter schedule, or delete the app’s local data. On iOS, deleting the app removes its local data; device backups may retain data according to your Apple backup settings. For the web app, clear this site’s data in your browser. Exporting creates a file containing your timetable, class names and locations. You choose where to save or share it.

Support

If you email support, your email address and the information you send are used to respond to your request. Do not send sensitive information that is unnecessary for support.

Website hosting

The public website is hosted on Cloudflare Pages. When you visit it, Cloudflare may process connection information such as your IP address and request details to deliver and protect the site. This is separate from the offline native app. Dayline does not enable Cloudflare Web Analytics.

Changes
