Terms of Use

Plain-language rules for using Lock My Devices and this website.

Last updated: October 3, 2026

Acceptance

By installing Lock My Devices or using this website you agree to these terms. If you do not agree, please do not use the service.

Use only on your own devices

Install the app only on devices you own or are authorised to manage, such as your children’s devices. Using it to lock someone else’s device without permission is not allowed.

Your user code

Your user code is the only key to your device group. You are responsible for choosing a strong code and keeping it secret. We cannot recover or reset a code for you.

Service availability

Lock commands depend on the internet, Google Firebase and Android. We work to keep the service reliable but cannot guarantee that every command is delivered instantly. Lock My Devices is not a replacement for a screen lock, backups or Google Find My Device.

Fair use of the website

Automated or repeated attempts to guess codes are prohibited and are blocked by rate limits.

Liability

The app is provided “as is”. To the extent permitted by law, QuanSystem is not liable for indirect damages arising from the use or unavailability of the service.
