“Privacy by Design” means that we view data protection not just as a legal requirement, but as a guiding principle for our products and services. From the outset, we integrate privacy measures into development – so you don’t have to compromise on privacy.
To use Threema, no phone number or email address is required. Your unique Threema ID ensures that you remain anonymous to both your communication partners and us. This way, you can communicate without leaving digital traces or revealing your personal network.
While other messengers collect your data for advertising purposes, Threema consistently refrains from advertising and tracking individual users. Our business model is based on direct payments instead of data trading – ensuring your communication remains 100% ad-free and private.
You decide whether and which contact data you want to share. Threema can be fully used without access to your address book. The optional synchronization is carried out exclusively with cryptographic hashes – keeping your contact list confidential yet usable.
Metadata often reveals more than the actual message content. That’s why Threema stores only the absolute minimum: messages are deleted from our servers immediately after delivery, connection information is not logged, and group memberships remain solely on your devices. This way, you leave virtually no digital footprints.
