Ember — Privacy Policy

Last updated: 5 June 2026

Ember does not collect, store, transmit, or sell any personal information. There are no accounts, no analytics, no advertising, and no third-party SDKs. Everything Ember does happens on your Mac.

Location

If you turn on Auto mode, Ember asks for your location. It is used only on your device, and only to calculate your local sunrise and sunset so the tint can follow the time of day. Your location is never stored, logged, or sent anywhere — not to us, not to any server. If you decline, Ember falls back to approximate civil times and still works.

What Ember stores

Ember saves your preferences (selected mode, strength, which displays and apps are excluded) in your Mac's standard app preferences, on your device only. This data never leaves your Mac.

No tracking

Ember contains no analytics, telemetry, crash reporting, or tracking of any kind. The only network activity is when you tap a research source link in the in-app "Science" window, which opens that page in your default browser.

Children

Ember does not collect data from anyone, including children.

Changes

If this policy changes, the updated version will be posted on this page with a new date.
