Our Mission
We built AppLock Pro because your phone holds more of your private life than ever before — and that privacy shouldn't depend on trusting a company with your data in the cloud.
Our mission is simple: give you complete, real control over who can access your apps and files — with security that lives entirely on your device, and a business model that doesn't rely on ads or tracking to survive.
Privacy & Legal
Your privacy is the entire reason AppLock Pro exists. Every credential, photo, and vault file stays on your device, under your full control, at all times — we do not operate any server that stores your personal data.
