Your data stays yours

Dayglow privacy policy

Effective date: September 2, 2026

Dayglow is designed to work without an account, cloud profile, advertising ID, or analytics service. Your daylight log stays on your device.

What Dayglow handles

Dayglow handles the information needed to provide its features:

How your information is used

Dayglow uses local app data to calculate your daily progress, streaks, goals, history, and statistics. Apple Health data is used only for the optional outdoor-time import feature.

Dayglow does not use your information for advertising, behavioral profiling, or marketing analytics.

Where your information is stored

Your Dayglow sessions, settings, and imported workout entries are stored locally on your device using the app’s on-device storage. Dayglow does not operate an account system, cloud sync, or server database for this information.

You can export a local JSON backup or import one from Settings. Exported files are controlled by you and may be stored or shared wherever you choose.

Sharing and third parties

Dayglow does not sell, rent, or share your daylight log or Apple Health data with third parties. Dayglow does not receive your payment information. Apple processes subscription purchases and manages billing through the App Store; Apple’s handling of that information is governed by Apple’s privacy policy.

Retention and deletion

Your local Dayglow data remains on your device until you remove it, delete the app, or replace it through an import. Deleting the app removes its local data according to your device’s operating-system behavior. Keep any exported backup files secure because they may contain your daylight log.

Children’s privacy

Dayglow does not knowingly collect personal information from children. Because Dayglow does not require an account and keeps app data on-device, it does not maintain a child user profile.

Changes to this policy

We may update this policy when Dayglow’s features or privacy practices change. The effective date at the top of this page shows when the policy was last updated.
