About Zumitomi Oy
Zumitomi Oy was established in 1997. Originally focused on importing automotive technology and providing management and marketing services. In the late 1990s, when good website builders were hard to find, we started building websites ourselves — beginning in 1999.
Over the years we have built and sold several web services. Today our main product is privis.app — a private messaging service built on the principle that personal communication should stay personal.
privis.app — Private messaging, on your terms
Most messaging apps demand your phone number and email. They build detailed profiles of who you talk to and when.
privis.app asks for none of that.
- Only a username and password
- No phone number • No email • No real name
- Works directly in your browser — no app install
- Multiple encryption levels, including true end-to-end
Privacy: only username and password - no data collection…
Why Privacy Matters
Your conversations are not inventory
They shouldn’t be scanned, profiled, or sold. True privacy means you stay in control.
Works for real life
Business discussions, personal matters, journalism, dating, or just everyday chats — without leaving a permanent data trail.
Built in Finland
EU jurisdiction, strong privacy culture, and transparent operation.
