Terms of use

Last updated: 11 November 2026

These terms apply to the use of the SafeXS and BellXS apps and the website safexs.eu, offered by Studio WebApp B.V., Amsterdam, the Netherlands (Chamber of Commerce 59040335).

1. The service

SafeXS lets authorised users open locks with their phone; BellXS lets visitors ring residents through a panel at the entrance. A lock system is set up for its owner, who decides who gets access. The agreement about the delivery, hosting and support of a lock system is made between the owner and Studio WebApp B.V. and takes precedence over these terms.

2. Your account

You get an account from the administrator of a lock system. Keep your password and phone secure and do not let others use your account. Tell your administrator straight away if your phone is lost or stolen, so your access can be blocked.

3. Use

Only open doors you are authorised to open and only share access within the limits your administrator set. Do not try to circumvent the security of the apps, the servers or the locks.

4. Availability

We work hard to keep SafeXS available and secure, and offline keys keep doors opening without the Internet. Still, we cannot guarantee that the service will always be uninterrupted, for example during maintenance or when a phone’s battery is empty. Make sure there is always an alternative way to open critical doors, such as an emergency key or an emergency exit.

5. Liability

As far as the law allows, our liability is limited to what is agreed in the agreement with the owner of the lock system. We are not liable for damage caused by misuse of an account, by sharing access with others, or by hardware that was installed or maintained by third parties.

6. Privacy

How we handle personal data is described in our privacy policy.

7. Applicable law

Dutch law applies. Disputes are submitted to the competent court in Amsterdam, unless mandatory law says otherwise.
