Privacy
Last updated August 19, 2026
The short version. Brightened collects nothing, transmits nothing, and has no servers. It reads one measurement from Apple Health on your device and shows it to you. That is the whole story.
What Brightened reads
Brightened requests read-only access to a single HealthKit data type: Time in Daylight. That measurement is recorded by Apple Watch using its ambient light sensor.
Brightened does not request write access to Apple Health, and it never will. It does not read any other health or fitness data of any kind.
Where your data goes
Nowhere. Your daylight data is read from Apple Health on your device, displayed in the app, and stored only in the app's own container and shared app group so the home screen widget can display it. It is never uploaded, synced, backed up to our systems, or transmitted off your device in any form.
There are no KSQ Studios servers involved in Brightened. There is nothing for us to see, because nothing is ever sent to us.
What we collect
Nothing at all. Specifically:
- No accounts, sign-ins, or user identifiers
- No analytics or usage tracking of any kind
- No advertising identifiers, and no advertising
- No crash reporting services
- No third party SDKs
- No cookies, because there is no web component
Your daily goal
The daily goal you set is stored on your device alongside the app. It is a preference, not a health record, and it is never transmitted anywhere.
Revoking access
You can withdraw Brightened's access to your daylight data at any time in the Health app, under Sharing, then Apps. Deleting Brightened removes everything the app stored on your device.
Children
Brightened is not directed at children and collects no information from anyone, including children.
Changes to this policy
If this policy ever changes, the updated version will be posted here with a new date. Given that the app collects nothing, substantive change is unlikely.
