Privacy Policy

Last updated: 10 November 2026

Who we are

Sleep Tiles ("the App", "we", "our") is a sleep habit tracker for iPhone made by an independent developer. This policy explains what information the App uses and where it goes.

Apple Health data

With your permission, the App reads these from Apple Health:

• Sleep: when you were in bed, asleep and awake, sleep stages where available, and which device or app recorded it.
• Overnight vitals: heart rate, resting heart rate, heart rate variability (HRV), breathing rate and wrist temperature. The App uses them for your morning readiness and to explain your nights.

The App never writes to Apple Health.

• Health data is processed and stored only on your device, to score each night and draw your grid, streaks and widgets.
• Health data is never sent to us, to Superwall or to any other third party.
• Health data is never used for advertising, marketing or data mining, and is never sold.

You can change or remove the App's access at any time in Settings → Privacy & Security → Health → Sleep Tiles.

Information you enter

Behaviour tags, notes, manually entered nights, the times you tap Going to bed and I'm up, and your settings (sleep goal, bedtime window, definition of a good night, colour palette) are stored on your device. If iCloud backup is on, they are also kept in your own iCloud (see below). Your iPhone may include them in your own iCloud or computer backup, as it does for any app.

If you use Export CSV, the App creates a file on your device and you choose where to share it. Nothing is sent anywhere unless you send it.

iCloud backup

So that a new iPhone or a reinstall gets them back, the App backs up your behaviour tags, notes, manually entered nights, bedtime and wake taps and settings to your own iCloud account, using Apple's CloudKit private database and iCloud key-value storage. This is on by default and can be turned off in Settings → iCloud backup.

• The backup is stored in your iCloud account, not on our servers. We cannot see, read or download it.
• Tags, notes and manually entered sleep times are end-to-end encrypted, so only devices signed in to your Apple Account can read them.
• Data from Apple Health and your scores are never stored in iCloud. On a new iPhone they come back from Apple Health.
• When you turn iCloud backup off, you can choose to delete the backup from iCloud.

Widgets

To show your grid and streak in widgets, the App saves a summary of your nightly scores in a storage area on your device that only Sleep Tiles and its widgets can read.

Notifications

If you turn them on, the App schedules reminders and summaries (such as a bedtime reminder, a morning summary, a weekly recap and a last-coffee reminder) on your device. They are created on your iPhone, and nothing is sent to us to make them. You can turn each one off in the App's settings or in iPhone Settings.

Subscriptions and Superwall

The App uses Superwall to show the subscription screen and to measure how it performs. Superwall receives:

• an anonymous, randomly generated app user ID;
• device and app details such as device model, iOS version, language, region, time zone and app version;
• subscription screen events, such as when it is shown, which plan is selected and whether a purchase or restore happens;
• your subscription status and purchase details from the App Store.

Superwall does not receive your sleep data, scores, tags, notes, name or email address. Superwall's own privacy policy is at superwall.com/legal/privacy-policy.

Payments

Purchases are handled by Apple through the App Store. We never see or store your payment details. See Apple's Privacy Policy.

What we don't do

• No accounts and no sign-in.
• No advertising and no ad tracking.
• No selling or sharing of your information.
• No servers of our own that store your data.

Not medical advice

Sleep Tiles is a wellness tool for building sleep habits. It is not a medical device and does not diagnose, treat or prevent any condition. Talk to a doctor about any sleep concerns.

Children

The App is not directed at children under 13, and we do not knowingly collect information from them.

Deleting your data

The App's data lives on your device and, if iCloud backup is on, in your own iCloud. Deleting the App removes it from your device. To remove the iCloud backup, turn off Settings → iCloud backup in the App and choose to delete it, or delete the App's data in your iPhone's iCloud settings. Deleting the App does not remove anything from Apple Health, which the App never changes. To ask about data Superwall holds for your anonymous ID, email us.

Changes to this policy

If this policy changes, we will update the date at the top of this page.
