Email [email protected] and say which phone and Android version you use. Never send your PIN.

Common fixes

• The lock screen doesn't appear: open Private Lock → Protection health. The accessibility service may be off, or a battery saver may have stopped it.
• Can't turn on the accessibility service (Android 13+): if you installed from outside Google Play, open Settings → Apps → Private Lock → ⋮ → Allow restricted settings, then try again.
• Disguised as a calculator and can't get in: press and hold the "isn't responding" message title until the phone vibrates, then enter your PIN.
• Forgot the PIN: we can't reset it (no account). Uninstalling clears the app's data, including the vault.
