The problem

Scattered work creates risk.

Files sit in one place. Feedback in another. Approvals disappear into email. Next steps get lost in chat.

  • Files and feedback get separated
  • Approvals get buried in email
  • Tasks lose context and ownership
When work is spread across email, chat, drives, and task tools, it creates more copies, more access points, and less control. Files can be forwarded, downloaded, duplicated, and discussed outside the system where decisions were made.
File Comments

Math over trust

Readable only
to you.

Qaxa encrypts locally, before anything leaves your device. Our servers store ciphertext, not content. If data is breached or seized, what others get is unreadable ciphertext—not your files, messages, or notes. Don’t trust us. Trust the math.
