One system for the shop — inbox, catalog, orders and payments. Kayan is its assistant, and a product you can use on its own.

Secure software engineering. Egypt since 2016. Encryption, access control, audit and isolation — from the first module.

Security

Not bolted on after launch. Designed in from the first module.

01
Encryption
Messages, memory and files are encrypted with a key unique to your account.
02
Isolation
Every user table is locked to your account. The app role cannot skip that lock.
03
No conversation logs
Conversation text is never written to logs, traces or analytics.
04
Access control
Personal and Work stay apart. Sastemny tools only ever appear in Work.

Personas are fictional characters. Kayan isn't a therapist and doesn't replace a teacher, doctor or lawyer.
