Your data is safe
Security is built into every layer of the application — from file storage to access control.
Encrypted connections
All communication happens over HTTPS/TLS. Files are stored in encrypted cloud storage.
Hashed passwords
User and share link passwords are hashed with bcrypt — never stored in plain text.
Expiring links
Set an expiration date for share links — access is automatically blocked after it passes.
Data isolation
Each organization's data is completely isolated. No access to other organizations' reviews.
Access control
Precise access levels — Viewer (view only) or Commenter (view + comments).
Authorization at every step
Every API request verifies session, organization membership, and permissions for the specific review.
