Privacy Policy

Layrest · Last updated October 27, 2026

Layrest plays sounds for sleep, rest and focus on iPhone and Android, and on iPhone it has an Apple Watch remote. It works without an account. This page describes, plainly, what the app does and doesn't do with your information on each of them. Where something differs between iPhone and Android, the section says so.

There's no account, and no server of ours

Layrest doesn't ask you to sign up, sign in, or create a profile. There's no backend of ours that your data is sent to. Everything the app remembers (your current mix and volumes, saved mixes, pulse and sleep-timer choices, a log of when sounds played, and settings) is stored locally on your device only. We never see it. Deleting the app deletes what it stored on your phone. If your phone backs up its apps (iCloud Backup on iPhone, or Google's backup on Android, if you've turned it on), that backup can include some of Layrest's data, and your phone can put it back if you reinstall Layrest. The backup is kept in your Apple or Google account, and we can't see it. Two things can leave your device, both described below: a feedback message, only if you choose to send one, and the purchase check that keeps Layrest Pro working.

Audio

Layrest only plays audio. It never uses your microphone and never records anything. The lock-screen controls and "Now Playing" information are handled by your device's operating system.

Apple Watch

Layrest on Apple Watch is a remote for Layrest on your paired iPhone, and the sound plays from the iPhone. What you choose on the watch, such as play or pause, a saved mix or the sleep timer, goes to your iPhone through Apple's Watch Connectivity, and your iPhone sends back what's playing, the timer, the names of your saved mixes and sounds, and whether you have Layrest Pro, so the watch can show them. Nothing is sent to a server of ours. There's no watch app for Android.

Notifications

Notifications from Layrest, such as the playback controls on your lock screen, are created on your device by the operating system, on iPhone and on Android. Nothing about them is sent anywhere.

Apple Health

Apple Health is on iPhone only. The Android app has no Health integration and doesn't connect to any health service. On iPhone, the Sleep screen can show how you slept on the nights each mix played. If you tap Connect Apple Health and allow it, Layrest reads the Sleep Analysis data your Apple Watch or iPhone records. It reads nothing else from Health and never writes to Health.

Layrest matches that sleep data against its own on-device log of when sounds played, and shows the result on your phone. Health data is never sent off your device, never shared with RevenueCat or anyone else, and never used for advertising or marketing. You can turn access off at any time in the Health app: tap your profile, then Apps, then Layrest.

Feedback

If you send feedback from Settings, the message you type is submitted to Formspree, a form-delivery service we use to receive it. Formspree forwards it to us, and we use it only to read and respond to your feedback. See Formspree's own privacy policy for how they handle it. You aren't asked for your name or email to send feedback.

Subscriptions

Layrest Pro is optional. Purchases are handled entirely by the store you got Layrest from (Apple's App Store on iPhone, Google Play on Android) and processed by RevenueCat, the subscription infrastructure provider we use to validate purchases and keep your Pro status in sync if you reinstall or switch devices. RevenueCat receives only what's necessary to do that (a purchase receipt and an anonymous identifier for your install), never your name, contacts, or anything else the app stores locally. See RevenueCat's own privacy policy, Apple's, and Google's for how each of them handles that.

What Layrest doesn't do

• No advertising, and no ad networks.
• No analytics or usage tracking of any kind.
• No selling or renting of your data, and no sharing beyond the two services named above (Formspree for feedback, RevenueCat for purchases), each only for the purpose described.
• No use of Apple Health data for anything except showing you your own sleep in the app.
• No tracking across other apps or websites.

Keeping and deleting your data

On your device: kept until you remove it. Deleting the app removes everything Layrest stored on your phone, on iPhone and on Android.

Phone backups: iCloud Backup and Google's backup follow your Apple or Google account's settings. You can delete a backup there.

Feedback messages: kept in our inbox only as long as needed to read and respond to them. Email us to have a message deleted.

Purchase records: RevenueCat keeps your purchase receipt and the anonymous ID so it can restore your access; its privacy policy says how long. Email us to have that record deleted. Apple or Google keeps its own purchase history under its policy.

Children

Layrest isn't directed at children under 13 and doesn't knowingly collect information from anyone in that age group. Apart from a feedback message someone chooses to send and the anonymous purchase ID, nothing leaves the device.

Changes to this policy

If this policy ever changes (for example, if a future feature needed to send data somewhere it doesn't today) this page will be updated and the "last updated" date above will change accordingly.
