Hosted in Switzerland

Swiss hosting. Honest about security.

Your data stays in Switzerland and is subject to Swiss law. During the beta it lives in our own homelab. We tell you exactly what we protect – and where the limits are.

Stored in Switzerland

Servers and encrypted backups in Switzerland: during the beta in our own homelab, later on bigger infrastructure. Your data does not leave the country.

Encrypted per customer

Each customer gets their own encrypted storage volume. The keys are kept separately in a key service – never on the storage server.

No routine admin access

Our team has no everyday access to your data. Emergency access requires two people, is logged permanently and you are informed.

Open source

Every building block is open source and publicly auditable. No lock-in: you can export everything at any time.

Frequently asked questions

Can you read my data?

Your data is encrypted on disk and in backups, and our team has no routine access. To offer search, face recognition and text recognition, our servers must process your data while it is running – that is why we don't claim to be “zero knowledge”. Any emergency access is logged and you are informed.

Where exactly is my data stored?

In Switzerland, including the encrypted backups. During the beta it runs on our own servers in a homelab; as we grow, we move to bigger infrastructure in Switzerland. Payments are processed by Stripe; logging in with Google or GitHub is optional.

Can I take my data with me?

Yes. Everything is based on open formats, and you can export photos, documents and history at any time.
