Last updated 11 August 2026

365 Sleep is an audio app. It plays sound, and it remembers what you listened to so it can show you your own history. That is close to the whole story. We do not sell your data, we do not run ads, and there is no analytics or tracking SDK in the app.

Who we are

365 Sleep is published by UofHappy, LLC. If you have a question about anything here, write to support@365sleep.app.

What we collect

What Why
Your name and email address To create your account and sign you in.
Your password Stored only as a one-way hash. Nobody, including us, can read it back.
Time zone So a night's listening is counted against the right day.
Subscription status To unlock the full library. Apple and Google tell us whether a subscription is active.
App settings Timer length, fade-out, frequency intensity and theme, so the app opens the way you left it.
Listening sessions Which soundscape or mix played, when it started and ended, and how long it ran — this is what your streak and minutes are calculated from.
Favourites and your own mixes So they are still there on your next device.
Support messages If you write to us from inside the app, we receive your message, your email address, and the platform and app version, so we can answer.

What we do not collect

The audio never leaves your device

Tones are generated by the app itself while it plays. Nothing is streamed and nothing is uploaded, so listening works with no connection at all. What syncs is the record that a session happened — not any audio.

Who else touches it

We use a small number of service providers, and only to run the app:

Our hosting provider
Runs the server and database that hold your account and listening history.
Postmark
Delivers transactional email, such as support replies and password resets.
Apple and Google
Process subscription payments and tell us whether your subscription is active.

We do not share your data with anyone else, and we never sell it.

How long we keep it

Your account and its data stay until you delete the account. Listening sessions are kept for as long as the account exists, because they are what your history is made of. Support email is kept for up to two years so we can follow up on a conversation.

Deleting your account

Email support@365sleep.app from the address on the account and ask us to delete it. We remove the account and everything attached to it — profile, settings, favourites, your mixes and your full listening history — within 30 days, and confirm when it is done. Deletion is permanent; there is no undo and no archived copy.

A cancelled subscription is separate: cancel it in the App Store or Google Play, since only they can end billing. See Support for the steps.

Children

365 Sleep is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has created an account, write to us and we will delete it.

Your rights

Depending on where you live, you may have the right to ask for a copy of your data, to correct it, or to have it deleted. Email support@365sleep.app and we will handle it within 30 days.

Changes

If this policy changes in a way that affects what we collect or who processes it, we will update the date at the top of this page and, where the change is significant, tell you in the app.
