App: Mellow - Sleep Better (Google Play package com.mellowsleep.mellow)

Developer: Mellowsleep

Last updated: 6 August 2026

This page explains how to delete your Mellow account, exactly what gets deleted, what is kept and for how long, and how long each route takes. It is publicly accessible - you do not need to sign in or have the app installed to read it or to make a request.

Option 1 - Delete in the app (immediate)

1. Open the Mellow app.
2. Go to the Profile tab.
3. Scroll to the bottom.
4. Tap Delete account.
5. In the confirmation dialog, tap Delete.

Deletion runs on our servers straight away, while you wait, and you are signed out as soon as it finishes. It is permanent and cannot be undone - your sleep plan, check-in history and progress cannot be restored, even if you sign up again later with the same email.

No confirmation email is sent for in-app deletions, because the deletion has already completed by the time the app signs you out.

Option 2 - Delete by email (no app needed)

If you have uninstalled the app or cannot sign in, email support@mellowsleep.com from the email address you used to sign in (your Google or Apple account), with the subject line "Delete my account".

• We verify that the request comes from the registered address before acting on it.
• Requests are completed within 30 days of verification.
• We confirm by reply once the deletion is complete.

Guest accounts

You can use Mellow without signing in. Guest accounts have no email or name attached, so we have no way to identify your data from an email request. Delete a guest account from inside the app (Option 1) before uninstalling. If you have already uninstalled, the leftover data cannot be linked to you or read by anyone, including us; write to support@mellowsleep.com if you have questions.

What is deleted

Deleting your account permanently removes all data linked to it from Mellow's systems:

1. Account profile - your email address, display name, account identifier (user ID), sign-in identity, sleep goals and challenges, push notification token (device identifier), and the link to any store customer record.
2. Sleep profile - your onboarding quiz answers: primary sleep complaint, how long you have had it, any doctor-diagnosed sleep disorder, and stress level.
3. Daily sleep check-ins - every check-in entry you have recorded.
4. Curriculum progress - which sessions and days you have completed.
5. Sleep story progress - where you were in each story.
6. Streaks - your streak counts and history.
7. Reminder settings - your bedtime and check-in reminder configuration.
8. App activity events - the first-party usage analytics tied to your account (sessions completed, audio played, check-ins responded to, notifications opened, and similar in-app events).

Your Firebase authentication record - the Google or Apple sign-in link itself - is deleted too, so nothing can be re-linked to the deleted data afterwards.

Anything stored only on your phone (downloaded audio, locally scheduled reminder notifications, app settings cache) is removed when you uninstall the app.

Mellow does not offer partial data deletion. There is no option to delete some of your data while keeping your account - deleting your account deletes all of the data above.

What is retained, and for how long

Some limited data is kept after account deletion, only where necessary:

Notes on the retained email hash: it cannot be reversed into your email address, and the record contains nothing else - no name, no sleep or health data, no activity history, no user ID (your user ID and the credit amount are erased at deletion). If you never claimed the reward, nothing at all is retained.

Your store customer record is not part of app-account deletion. To have it removed as well, say so in your email to support@mellowsleep.com and we will delete it, apart from records we are legally required to keep for completed orders.

Retained data is stored securely, is not used for marketing after account deletion, and is never sold.
