Frequently asked questions

Is there a mobile app?

We recommend the OX Drive app for Android or iOS.

You also have the option of using the webmailer and the progressive web app (PWA). However, these only allow you to access your files, not manage them.

Can I encrypt my files?

Yes, your data can be encrypted with OpenPGP – both during upload and storage. Encryption takes place on the client side, so only you have access to the content. This means that your files are also protected from unauthorized access on the server.

Can I share files with others?

Yes, file sharing is possible – securely and in compliance with GDPR, e.g. via links or within shared folders.

Where are my files stored?

Your files are stored exclusively in our own data centers in Germany – distributed across two independent locations in Berlin. The infrastructure is secured with multiple redundancies and meets the highest security and data protection standards under German law.

What collaboration options are available?

You can work together on documents, use global calendars and resources, chat in real time, and collaborate securely with external parties. This makes mailbox Office ideal for teams and projects in companies or for families.
