Licensing & Terms

Clear, simple, and fair.

OneArch is currently completely free during early access, with all features available to everyone.

The product helps architects save time, make better decisions, and document architecture efficiently — and it's fair that, over time, it may become a paid product.

That said, we make a clear commitment:

  • If OneArch introduces paid plans in the future, you will always be able to access and export all your data (projects, ADRs, diagrams, requirements) — without paying.
  • No lock-in — you’ll never be blocked from retrieving your work or migrating elsewhere, even if you decide not to continue with a paid version.
  • You’ll have a clear option to leave with all your data fully intact, no tricks or restrictions.

Intellectual Property

OneArch is the sole intellectual property of its creator (Nick/Nikolai Laptev).

Using the product during early access does not grant rights to reuse, reproduce, or redistribute any part of its interface, logic, or design.

You are welcome to explore and benefit from it — but the product itself remains protected.
