Lockt

Lockt保护您和您的数据之前，你解锁设备后

Lockt looks and acts like a standard lock screen. Enter the correct pattern and your phone unlocks, enter the wrong pattern and it stays locked.

But... Lockt also lets you quickly and quietly select some actions while entering the unlock pattern. You decide which actions run. They run before your device unlocks. Most run silently, only you know they ran.

Lockt has 18 actions, including ones to wipe external storage, send SMS and email messages, reset the device, take photos and record audio. More actions are on the way.

We all keep private information on our phones and tablets. Contacts, banking details, family photos, videos, appointments, meeting notes, call logs...

Good passwords and encryption help keep this safe, but sometimes you have to hand your unlocked device over to someone else.

Lockt Lock Screen can help protect you, your data, and your devices

If you just want to unlock and use your device, enter the unlock pattern and you're in

If you want to run some of Lockt's actions, tap the icons matching the action sets, then enter the unlock pattern. The action sets run and your device unlocks.

Lockt's actions include:

- Wipe External Storage

- Delete Named Directories

- Overwrite Free External Storage (to prevent recovery)

- Wipe and Overwrite External Storage, Then Perform a Factory Reset

- Delete Call Logs

- Delete Calendar Entries

- Backup and Delete Contacts

- Take Photos

- Record Audio

- Send An SMS Message With Your Location

- Send An Email With Your Location

- Perform a Factory Reset

- Uninstall Lockt

- Make Lockt look like a standard lock screen app

And more, with more to come

You combine Lockt's actions into action sets, then select and run action sets as you unlock your device. Creating action sets is quick and easy

An example of where Lockt may be useful is going through passport control. You hand over your passport. The officer tells you to unlock your mobile phone so they can search it. Maybe they'll copy your data as well (1). If you refuse you'll be delayed and given a hard time. Your device may be seized, you may be refused entry, detained and deported. Couldn't happen? In 2016 over 19,000 mobile devices were searched by the US Customs and Border Protection Agency (2). That's up from about 8,500 in 2015 (2).

To protect yourself and your privacy set up Lockt action sets. Then select and run action sets as needed.

For example, you could create action sets that

delete some directories and then overwrite free external storage to prevent recovery

send an SMS message with your location to multiple recipients

start recording audio and taking photos

run a full factory reset after a configurable delay, you can cancel during the delay

... or any other combination of Lockt's actions

To run an action set simply tap its icon before entering the unlock pattern.
