Find your situation

You do not need to know the security vocabulary. Start with the problem you are trying to solve.

Phone handoff

“I want to show one photo without exposing the rest.”

Reduce accidental swipes into nearby photos when another person is holding your unlocked phone.

See the safer handoff workflow Repair visit · Android

“Someone else needs physical access to my phone.”

Prepare a backup, reduce visible copies, use repair mode where supported, and check the device afterward.

Prepare for a repair Device change · Android

“I am getting a new phone and cannot lose my vault.”

Move a portable encrypted backup, test the restore, and only then decide what to erase on the old device.

Plan the move Recovery

“Is my recovery phrase the same thing as a backup?”

No. One can restore access; the other preserves the encrypted data. Learn why a recovery plan needs both.

The four questions behind every guide

What copy exists? The source, vault copy, thumbnail, cloud backup, export, message attachment, or recipient copy may have different protection.
Who holds the key? A device passcode, app pattern, platform key store, account credential, recovery phrase, and backup phrase are different controls.
What happens after loss? Privacy without a tested recovery plan can turn a broken phone into permanent data loss.
Where does protection stop? No vault protects content that is open onscreen, already exported, saved by a recipient, or exposed by a compromised operating system.

How examples work

Names and situations in examples are fictional. They show how a decision changes the number and location of copies; they are not promises about a particular device configuration. Exact operating-system steps can change, so platform-specific guides link to official Apple, Google, Android, or Samsung documentation.

How NullVault claims are handled

Feature descriptions explain the released iOS and Android apps separately where their behavior differs. A statement about encryption, recovery, backup, duress, or deletion is scoped to NullVault's documented design and security limitations. The guides do not claim that encrypted data is invisible, physically erased, or safe while displayed on a compromised device.
