Private by default
Files live in private storage and are only served after server-side authorization.
Security at Ottowrite
A secure path to the right reader.
Manuscripts are valuable intellectual property. Ottowrite is designed so they are private by default, delivered deliberately, and never exposed as public files.
Verified readers
Invite links are single-purpose and require recipient email verification.
Author-controlled access
Choose view-only or downloadable access, then expire or revoke it later.
Personalized watermarks
Optional preview watermarks identify the verified reader and access session.
Immutable audit trail
Opens, previews, downloads, responses, and revocations are recorded.
Layered safeguards
Malware quarantine, rate limits, signed webhooks, RLS, and least-privilege services.
