🗝️One-Time Secret
Share a password or note via a link that works exactly once.
Why ShareNimbus
Email attachments live forever and get forwarded; shared drive links linger long after they should. ShareNimbus makes sharing temporary by default: every link carries an expiry, and the file is deleted automatically when it lapses — no cleanup, no lingering exposure.
Built for the moment you need to hand someone a document, a build, or a credential and have it disappear on schedule. Files are stored on Cloudflare R2 with zero egress fees; secrets can be one-time-view so reading the link consumes it.
