Secure and Ephemeral Secret Sharing

Share your passwords, API keys, private tokens, and confidential documents with complete peace of mind. Parchemin provides client-side encryption with self-destructing links.

Sending sensitive information by email, Slack, Teams, or support ticket leaves a permanent plaintext record on servers, logs, and backups. Parchemin eliminates that risk: your secrets exist only for as long as needed and can only be read by their intended recipient.

TLDR; => Try it

Zero-knowledge end-to-end encryption*

🔒 Your note is encrypted directly in your browser using the proven OpenPGP standard before it is ever sent to our servers. The decryption key exists exclusively in the URL fragment (`#`) and is **never sent to or stored on our servers**. We cannot read your notes, even if we wanted to.

Self-destruction and ephemeral data

💣 Configure your notes to self-destruct after their first reading ("burn after reading") or set an automatic expiration time (from 1 hour to 30 days). Once viewed or expired, the encrypted payload is permanently and irrevocably deleted from our systems.

100% ad-free and tracker-free

🚫 Unlike legacy tools such as Privnote, Parchemin contains no advertising, tracking pixels, or third-party analytics scripts. Your security should never be compromised by ad networks or tracking.

Built for teams and businesses

🏢 Manage confidential sharing across your organization. Parchemin allows administrators to enforce compliance rules and security guardrails:

Mandatory expiration cap: Prevent secrets from persisting beyond internal policy.
Required secondary password: Require an additional passphrase for certain domains or workspaces.
Strict single-read rule: Force self-destruction on first opening.

No recipient account required

⚡ Easily share with external providers, customers, or colleagues. Recipients can open and decrypt the note instantly in any modern browser, without creating an account or installing an application.

How does it work?

Create your note: Write your message, upload a file, or record an audio note.
Set your security options: Choose an expiration period, enable burn-after-reading, or add a password. (For team members, company policies apply automatically.)
Share the encrypted link: Parchemin generates a unique, single-use link containing the client-side decryption key. Send this link to your recipient through your usual channel.
Permanent destruction: As soon as it is read or expires, the encrypted content is irreversibly deleted from our database.
