Account and data deletion
Delete your Calmivelle data
Your journal stays on your phone. This page shows how to remove it, and how to ask us to delete what our server holds, even when the app is no longer installed.
Which app this is about
Calmivelle - CBT & Sleep, the self-help app for iPhone, iPad and Android. It is a wellbeing tool for adults. It is not a medical device and does not diagnose, treat, cure or prevent any condition.
Deleting your data needs no login and no subscription.
The quickest way: in the app
- Open Calmivelle and go to Settings.
- Choose Your data.
- Choose Delete all my data and confirm.
This removes your journal, check-ins, sleep diary, safety plan, reminders and choices from the phone. If you had turned on AI features, it also asks our server to delete its records for your installation.
No app, or a lost phone? Ask us here
Enter your data reference. The app shows it under Settings, Your data. It looks like this: 3f2b6c1e-8a4d-4e0b-9c57-1d2e3f4a5b6c
Request received
If that reference matches a record, its server data will be deleted within 24 hours. This page shows the same message whether or not the reference matched, so it cannot be used to check whether a reference exists.
Your receipt is random and is not linked to any stored data. Keep it only if you want to refer to this request.
This does not touch data on your phone. The app's Delete all my data, or removing the app, does that.
Our server holds no name or e-mail address, so the reference is the only way we can tell which record is yours. If you turned on AI features and no longer have the reference, we cannot find the record. It holds no journal text.
What is deleted
- the installation record: its ID, public key, platform and app version
- your AI consent record
- the link to your purchase, and the store's purchase proof
- usage records for this installation
- reports you chose to send about an AI reply
- the anonymous sign-in account the app created for you
Your journal, check-ins, sleep diary and safety plan were never on our server. If you never turned on AI features, the server holds nothing about you.
What is kept, and for how long
- A deletion marker, 90 days. A one-way hash of the installation ID, the deleted public key, a hash of the anonymous account ID and the time of deletion. It lets a repeated request work and stops the same ID being registered again.
- Daily AI usage counts, until the end of the day or month. They are tied to a one-way hash of your purchase, not to you, so that deleting and starting again cannot reset the daily allowance.
- Server logs, until they rotate. They hold a request ID, the feature, status, timing and sizes, never content.
- Usage statistics and crash reports already sent to Google Firebase stay under Firebase's own retention settings. They hold no journal text and no name.
The privacy policy explains each of these in full.
Deleting data does not cancel your subscription
Billing runs through Apple or Google until you cancel there.
- iPhone or iPad: Apple's guide to cancel a subscription.
- Android: Google's guide to cancel, pause or change a subscription.
If you come back later, use Restore purchases in the app to get your membership back.
