AutoErase is a simple, yet autonomous and reliable anti-data-thief application. It helps you to mitigate risks that the sensitive data will be unfavorably disclosed from a missing or stolen Android device.

You can’t disable test mode.

Upgrading:
When upgrading from the trial to the full version, you need to retain the trial version.

Function:
- When the number of failed unlock attempts reaches the limit that you specified, AutoErase will reset the device to factory default and erase all user data.
- When the unlock attempts fail, messages warning that the device will be erased after certain number of unsuccessful attempts, will be displayed on the lock screen at the timing of your choice.

User friendly features:
- Simple main screen allows you to access all necessary settings, and to confirm the current settings at a glance.

Question and answer (detail):

Q1. What does AutoErase exactly do when the erase condition meets?
A1. AutoErase will ask Android to start the factory reset operation, with option to erase user data set. In standard Android implementation, this will cause the exactly same thing as you reset your device manually from the settings menu with option to erase user data set.

Q2. Dose AutoErase really erase all user data?
A2. No, AutoErase does not erase some user data in many cases. What data are not erased depends on the way how OEM implemented Android. For example, AutoErase may not erase micro SD card on recent Android devices with large built-in flash memory, on which a part of the flash memory is treated as internal SD card.

Q3. Dose AutoErase perform secure-erase?
A3. It depends on implementation of Android by the OEM, and the answer is no in most cases. If you seriously want to have your device securely erased, please consider use of encryption of storage together with AutoErase. The cipher key of the properly implemented cryptographic file system should be securely erased by resetting the device to factory default. This practically takes the same effect as erasing the whole storage securely.

Q4. Do I still need AutoErase even if I have my storage encrypted?
A4. Many of you will want to use AutoErase even in such condition. Please remember the fact that you can use data stored in your device once you successfully unlock the device, regardless of whether the storage is encrypted or not. The problem here is that it is difficult to make the unlock password very strong, because you need to enter it so many times a day. Your unlock password may not be strong enough to ignore the risk that some bad guy might successfully crack the password by making guesses or a brute-force attack. AutoErase will effectively mitigate such risks.

Q5. I forgot my password while in test mode. What should I do?
A5. Keep trying the passwords you can remember. When the number of the failed attempts exceeds the setting for erasing by 5 or more, the test mode allows you to choose the erase option. AutoErase will reset your password to factory default (usually none) together with all other settings when you choose this option. User data and downloaded applications will be erased as well.
