Built on clear principles
Useful before impressive.
Nulleuri is an independent software studio. We prefer one well-defined problem, honest product boundaries and privacy people can understand.
One problem
A product earns its place by solving a recognisable job.
Clear status
Available, in review, release candidate and development are never presented as the same thing.
Plain privacy
Every app explains local data, permissions, third parties and deletion.
No invented proof
No fake reviews, download counts, awards or customer logos.
Independent by design
A small studio with a long view.
Nulleuri is the public software identity of an independent Estonian studio. Products are published by Blacksunset OÜ. The catalogue grows one useful application at a time.
