AppLock by DoMobile

AppLock is a widely used mobile security application designed to protect user privacy by locking specific apps, photos, and videos with passwords, patterns, or fingerprint authentication. It was originally launched in 2012 by DoMobile Lab, a mobile internet company known for developing utility and productivity tools for the Android ecosystem.

Historically, the app gained massive popularity, reaching over 500 million downloads worldwide. However, it has been the subject of regulatory scrutiny in several regions. In 2020, AppLock was notably included in a list of applications banned by the Indian government due to concerns regarding data security, privacy, and sovereignty. The developer, DoMobile, is headquartered in Hong Kong, which is a Special Administrative Region of China, and the app's development and data management are rooted in that region.

While multiple apps with the name 'AppLock' exist on various app stores (including versions by App Lock LLC in the US), the original and most prominent version remains the one developed by DoMobile. Users should be aware of the brand's region-specific availability and the privacy policies associated with its Chinese parent company.
