Your digital life.Under your control.
STER builds privacy-first mobile devices and secure communications. We work with the leading open-source encryption projects so your data stays yours.
Secure devices, ready to use.
Every phone is configured by STER with privacy as the starting point. Choose your model and order online.
Prices in euros. Shipping and availability depend on your country.
Privacy is not a feature. It is the foundation.
Data is exposed in three places: on the device, on the network and in storage. We design for all three.
End-to-End Encryption
Messages and calls are readable only by the people in the conversation, not by the network that carries them.
Encryption at Rest
Data stored on the device is encrypted, so a lost or seized phone does not mean exposed information.
Encryption in Transit
Traffic is protected while it moves between your device and the services you choose to use.
Control over who sees what.
Data protection, private communications and access control, built into the device from the first boot.
Data protection
Fewer permissions, fewer trackers and local-first storage keep your information on your device.
Private communications
Secure messaging and email tools set up and ready to use, from open-source projects you can inspect.
Access control
You decide which apps, accounts and people get access, and you can revoke it at any time.
Security architecture
How an encrypted message travels: it is encrypted on your device, crosses the network as ciphertext and is decrypted only on the recipient's device.
Principles we build on
Three rules that guide every product decision.
Privacy by Design
Privacy is the default setting, not an option you have to find and turn on.
Security by Design
Protection is part of the architecture from the first decision, not added at the end.
Data Minimization
We collect only what is needed. Data we never hold cannot be lost, leaked or requested.
Technology we work with
Product names belong to their respective owners. Working with a project does not imply endorsement.
Available worldwide
Availability and shipping depend on local regulations.
Transparency
Trust is earned by showing how things work.
