Core Features

Managing File Self-Destruct Timers (TTL)

Every file in UltraLocked has a self-destruct timer, also known as Time-To-Live (TTL). When this timer expires, the file is permanently and securely deleted. You can change this timer for any file at any time.

What is a Self-Destruct Timer?

The self-destruct timer is a core security feature of UltraLocked. It ensures that sensitive data does not persist on your device forever, protecting you from future compromise or accidental discovery.

  • The timer starts from the moment the file is created or imported.
  • When the timer reaches zero, the file's encryption key is destroyed and the file's data is overwritten, making recovery impossible.

How to Change a File's Timer

You can adjust the timer for any individual file.

In List View:

  1. Find the file in your vault.
  2. Tap the Ellipsis (...) icon on the right side of the row.
  3. Select "Change Expiration".
  4. Choose a new duration from the list (e.g., 5 Minutes, 24 Hours, 1 Year).

In Grid View:

  1. Long-press on the file's thumbnail to bring up the context menu.
  2. Select "Change Expiration".
  3. Choose a new duration.

While Viewing a File:

  1. When viewing an image, video, or document, tap the screen to show the controls.
  2. Tap the Ellipsis (...) menu icon.
  3. Select "Change Expiration" and choose a new duration.

Setting the Default Timer

You can change the default self-destruct timer for all new files you add to the vault.

  1. Navigate to Settings.
  2. Under the "Preferences" section, tap on "Default Self-Destruct Timer".
  3. Select a new default duration.

This setting will apply to all files added via the Secure Camera, Secure Notes, or the Share Extension from that point forward.
