Delete your account or cloud content

An account is optional. In the app, open Account & cloud sync to delete only your active cloud content, or to delete the account and its cloud content. Account deletion also revokes sign-in sessions; if a provider or cloud deletion step is temporarily unavailable, the disabled account remains queued for retry. Local notes on your device are separate and remain available.

Deleting the Nostella account does not cancel an App Store subscription. Use Apple subscription settings to stop auto-renewal. Removing a waitlist entry or support email is also a separate request.

Delete or restore an item

  1. Use the item’s Delete action in Nostella. Supported notes, folders, reminders and voice memos move to Recently Deleted.
  2. Open Settings and find Recently Deleted. Authenticate if you have enabled its protection.
  3. Choose Restore to bring an item back, or use its permanent Delete action to remove it from recovery.

The recovery window is 30 days unless you permanently delete the item sooner. Expired entries are removed when the app performs its cleanup; an app that is not running cannot guarantee cleanup at an exact moment.

What permanent deletion means

Permanent local deletion removes an item from recoverable records and removes associated files that Nostella can prove are unused. A shared or legacy file may remain to protect other content. This is not secure physical erasure.

For cloud sync, uploads stop after trial or subscription expiry. Deliberate recovery download remains available through a 30-day grace period and seven-day final warning. The hourly server job removes active cloud content at or after day 37; paying again before deletion cancels that purge. You can delete active cloud content sooner. Encrypted infrastructure backup copies can remain up to 30 days after active deletion under the configured backup retention policy. Operating-system backups, exports, Photos and recipients’ copies are separate.

Removing the app from a device

Before removing Nostella, keep any content you still need. On iPhone or iPad, use Delete App to remove the app and its ordinary local app data. Offload App keeps documents and data, and removing an icon from the Home Screen does not delete the app.

On Android, the operating system’s app storage controls can clear app data, and uninstalling removes the installed app. Labels vary by manufacturer. Check the confirmation carefully: clearing app data is destructive.

These actions do not promise deletion of separate backups, files saved outside the app, recipients’ copies or every system-managed security record. Review your platform’s backup and storage controls separately.

Waitlist and support information

Email support@nostella.app to ask thunderflow x to remove your waitlist email, or to access, correct or delete personal information you sent in support correspondence. Please identify the address you used. We may verify the request and retain information where applicable law requires it.

Do not attach a notebook or disclose a vault password. We cannot remotely delete local app content or erase a copy held by a recipient you chose.
