These smart anti-theft tools help make lost phones a thing of the past:

Lock your phone, preventing unauthorized access.

Locate it by pinpointing its coordinates on a map.

Prompt the person who finds your phone to contact you with one tap.

Trigger a loud yell

You know your phone is close, but can’t find it? Trigger a loud yell to find your phone under the couch… or in someone else’s pocket.

Wipe your phone’s contents

Lost your phone? Thieves may have your phone — but not your data; remotely wipe all sensitive content from your phone, including emails, credit card details, and text messages.

Remote or in-app — we’ve got
your back

Remotely trigger your anti-theft tools from the online dashboard or in-app from any of your registered Android devices (no limits!).
