Delete your account and data

Last updated 10 November 2026

This page explains how to delete your Siyan Somnus account, and the data in it, from Siyan Clinical Corporation. There are two routes: inside the app, or by email if you no longer have the app installed. You do not need to reinstall Somnus to ask us to delete your account.

Cancel your subscription first. Deleting your Somnus account does not cancel an App Store or Google Play subscription. Those are held by Apple and Google, not by us, and they will keep charging you after your account is gone. See cancelling your subscription below.

Before you delete: take a copy

Deletion is permanent and we cannot bring anything back. If you want your nights, your notes or your conversations, export them first: Profile → Export your data in the app. Pick what to include and Somnus builds a plain JSON file you can save or send anywhere. It takes a few seconds. The Delete account screen also offers the export as a last step before you confirm.

Route 1 — in the app

  1. Cancel your subscription in the App Store or Google Play (see below).
  2. Open Somnus and go to the Profile tab.
  3. Tap Privacy and security.
  4. Under Your data, tap Delete my account.
  5. Read the list of what will be removed. There is an Export my data first button here if you want a copy.
  6. Tick I understand my data will be permanently deleted. You can also leave a note about what we could have done better — it is optional.
  7. Tap Delete my account, then confirm Delete permanently in the dialog that appears.

Your data is deleted straight away, you are signed out, and the app returns to the welcome screen. There is no waiting period and nothing to confirm by email.

Route 2 — by email, without the app

If you have deleted the app, lost the device, or cannot sign in, email us and we will do it for you.

Email support@siyanclinical.com

If we cannot match your message to an account, we will write back and ask — we will not delete an account on an unverified request. We action verified requests as soon as we can, and in any case within 30 days, and email you when it is done.

What is deleted

Everything Somnus holds about you as a member, removed from the live service immediately and permanently:

None of this is recoverable. We do not keep a copy to reactivate, and signing in again with the same email afterwards gives you an empty account, not your old one.

What is not deleted, and for how long

Being straight about the edges:

What you logged in Apple Health or Health Connect stays in Apple Health or Health Connect. Somnus only ever read from them and never wrote to them, so there is nothing of ours to remove there. Delete those records in your phone's own health app if you want them gone.

Cancelling your subscription

Separate from deletion, and it has to be done in the store that bills you. We cannot cancel it for you.

Cancel at least 24 hours before the current period ends, or the next renewal will already have been taken. If you delete your account first and forget this, the charges continue — ask Apple or Google for a refund, as only they can issue one for a store purchase.
