FAQ

Questions about device health & system trust.

Ask us directly
What does system tamper detection look for?

It checks whether your phone's operating system has been altered, rooted, or jailbroken, which could allow rogue apps to bypass normal phone security protections.

How does pairing a new family device work?

Open Zdefence on your new phone and scan the secure QR code displayed on your primary phone. The device is verified and enrolled in seconds.

What happens if a family phone is lost?

From any other authorized device in your family plan, you can tap 'Revoke Access'. The lost phone is immediately disconnected from your shared account and vault.

Does this slow down my phone?

No. Checks are lightweight, native, and run in milliseconds without consuming noticeable battery or processor power.
