DayGlint privacy policy
In short
DayGlint reads your Apple Health data and works everything out on your iPhone and Apple Watch. We collect nothing, sell nothing and share nothing. There is no account, no analytics and no advertising.
What DayGlint reads
With your permission, DayGlint reads data from Apple Health: heart rate and heart rate variability, sleep, workouts, activity, body measurements and the other types listed in the Health permission sheet. You choose which types it may read, and you can change that at any time in the Health app or in Settings. Types you do not allow look like missing data to DayGlint.
Sleep from your iPhone’s motion
This is an option you turn on. With your permission, DayGlint reads your iPhone’s motion data (the motion activity history and the accelerometer recorder of Core Motion) on the device, to estimate when you slept on nights without your Watch. Raw motion readings are never stored. DayGlint keeps short summaries of when the phone lay still or was in use (in detail for the last 40 hours, a summary of each night for 30 nights), the times you opened DayGlint (8 days), the bedtime and wake signals your Shortcuts automations record (45 days), and each night’s estimate and your answers to the morning question, with your daily summaries. None of this is uploaded, included in iCloud Backup or exported, and estimates are never written to Apple Health. Turn the option off, or remove Motion & Fitness access in Settings, and DayGlint stops reading it; Delete all data removes what it kept.
What DayGlint writes to Health
Only what you ask it to save: activities you log in DayGlint, and the effort ratings you give your workouts.
What DayGlint keeps, and where
- On your iPhone: daily summaries for up to 400 days, your usual ranges, the tile layout, your profile and your settings, in DayGlint’s own storage on the device.
- Not in iCloud Backup: the summaries worked out from your health data are left out of iCloud Backup. After you restore a backup or move to a new iPhone, DayGlint builds them again from Apple Health. Your profile, settings and tile layout are part of the backup, so they come back with it.
- On your Apple Watch: the last 14 days of summaries, sent straight from your iPhone to your Watch (device to device), and what the Watch works out for today.
- In iCloud: besides your device backup, only the tile layout (which tiles, in what order and size), so a new iPhone starts with your board. It holds no health data.
Siri and Shortcuts
The Siri and Shortcuts actions run on your devices. They read the same summaries the app shows; "Record a sleep signal" saves only the event and its time, on your iPhone. DayGlint sends nothing anywhere for them.
The network
DayGlint has no servers. It uses the network for two things only: iCloud key-value storage for the tile layout, and opening this policy’s web page when you tap its link. It contains no analytics, no advertising, no tracking and no third-party code that collects data.
Health data
Data from Apple Health is never used for advertising or marketing, never sold, never shared with anyone, and never stored in iCloud by DayGlint. It is used only to show you your own numbers.
Notifications
Notifications are made on your iPhone from your own summaries. Some show numbers, such as your recovery. You can turn each one off in You › Notifications, or hide previews on the Lock Screen in Settings.
Export and delete
You › Data and privacy › Export data makes a file of your summaries, usual ranges, layout, profile and settings and hands it to the share sheet; you decide where it goes. The phone’s sleep summaries stay on the iPhone. Delete all data removes everything DayGlint keeps on your iPhone and on your Apple Watch. Your data in Health stays as it is. Deleting the app also removes what it keeps on the device.
Children
DayGlint is not directed at children, and it collects no personal information from anyone, of any age.
Changes
If this policy changes, the new text appears in the app and on the web page with a new effective date.
