Your sleep stays yours.

Last updated 21 August 2026

Bedhead is built around a simple idea: the app should show you your sleep without ever taking it from you. There is no Bedhead account and no Bedhead server. We can't see your data, because it never reaches us.

What Bedhead reads

With your permission, Bedhead reads the following from Apple Health — all of it already recorded by your Apple Watch or a compatible tracker:

• Sleep analysis — the nights themselves: when you slept, and your stages.
• Overnight vitals — heart rate, resting heart rate, heart rate variability, respiratory rate, wrist temperature, and blood oxygen.
• Workouts — how long you moved on a given day, to show what your days do to your sleep.

Each of these is aggregated on your device into one set of numbers per night, and used only to show you last night, your averages, your stages, and your trends inside the app. Overnight vitals and workouts are optional — you can turn either off in Settings → Health data, and Bedhead will stop reading it. Bedhead never writes to Apple Health, and reads nothing from it beyond what's listed above.

Where your data lives

Your sleep history is stored on your device and in your own private iCloud (Apple's CloudKit private database), held under your Apple ID — so it's backed up and comes back if you reinstall or set up a new iPhone. It is held under your account, not ours. We have no access to it, and it is never sent to a Bedhead server — there isn't one.

Your settings — wake time, sleep target, and preferences — sync through Apple's iCloud key-value store, again under your Apple ID.

Your weekly summary

Bedhead's Trends tab shows a short written summary of your week, and the month-by-month view shows one for your year. These are written by Apple's own language models, and the numbers in them are worked out by the app first — the model is only asked to put them into sentences.

Depending on your device and how busy it is, that runs either entirely on your iPhone or through Apple's Private Cloud Compute — Apple's own servers, which Apple states cannot retain your data and which are open to independent inspection. Either way it is Apple's infrastructure under Apple's privacy terms, and either way nothing reaches a Bedhead server — there isn't one. Only the handful of numbers being described is sent, never your sleep history. If your device can't run these models, the summary simply doesn't appear.

Siri and Spotlight search

Bedhead makes two things available to your iPhone's own search and voice features, both on your device:

• Tonight's bed-by time — so you can ask Siri when to go to bed. Siri works this out from your wake time and sleep target, the same as the app does.
• Your recent nights — so a night can be found through Spotlight search, showing how long you slept and when you went to bed and got up.

This is handled by Apple's on-device index. Nothing is uploaded, and Bedhead can't read it back out. Deleting your sleep history, or turning Health Access off in Settings, removes your nights from search along with everything else.

What we don't do

• No analytics or tracking SDKs.
• No advertising, and no advertising identifiers.
• No selling or sharing of your data — we never receive it to begin with.
• No location, contacts, microphone, or camera access.

Subscriptions

Bedhead's premium tier (the Bedtime Plan and Trends tabs) is an auto-renewing subscription billed by Apple through the App Store. Purchases are handled entirely by the App Store using Apple's StoreKit; Bedhead never sees your payment details. Bedhead does not use any third-party subscription or analytics SDK, and does not send your purchase information to anyone other than Apple. Your subscription and purchase data are processed by Apple under Apple's privacy policy, and your subscription follows your Apple ID if you reinstall or move to a new iPhone.

Notifications

The optional wind-down reminder is scheduled locally on your device and delivered by iOS. It's off by default, and nothing about it leaves your phone.

Your controls

• Delete your history any time in Settings → Delete Sleep History. This removes Bedhead's stored history from your device and iCloud; your Apple Health data is untouched.
• Revoke Health access in the iOS Settings app under Privacy & Security → Health.
• Manage or cancel your subscription in your App Store account settings.

Children

Bedhead is not directed at children and is not intended for use by anyone under the age required to hold an Apple ID in their region.

Changes

If this policy changes, we'll post the new version here and update the date above.
