Auto-lock and privacy screen: nothing left open behind you

Updated 22 October 2026 · By Hidy

Hidy locks the vault the moment the app goes to the background. While it's inactive, a privacy screen covers its content, including the app switcher preview and any photo or document viewer that was open.

Quick answer
  • Leave the app and the vault locks. Reopening needs the pattern again.
  • The app switcher shows a cover, not your photos.
  • A separate privacy window also covers open viewers while Hidy is inactive.

Why this matters

Most privacy slips happen in seconds: you switch to Messages, hand the phone over, and the last app you used is one swipe away. A vault that stays open after you leave is only as private as the next person to pick up the phone.

What Hidy does

Want photos your iPhone passcode can't open?

Where it stops

Habits that help

  1. Lock Hidy before you hand someone the phone.
  2. To show one photo, open it in a vault that holds nothing else sensitive. See show one photo without letting someone swipe.
  3. Keep the most private files behind a pattern you never draw in front of anyone.

Frequently asked questions

Can I set a delay before Hidy locks?

Hidy locks as soon as it goes to the background, so a vault is never left open when you switch apps or lock the phone.

Does Hidy block screenshots?

No app can stop every way of capturing a screen. Hidy covers its content when inactive and in the app switcher. While a vault is open, what's on screen is readable.

What happens to files I was viewing?

Temporary decrypted copies used for viewing are cleared when the vault locks.
