LevConfide™
Encrypted, one-time secret links for confidential text that should not remain in ordinary messages.
Private information exchange
Focused software with a clear job.
LevConfide™ encrypts confidential text with AES-256-GCM directly in the sender's browser, before anything reaches a server, then hands back a one-time link. The decryption key lives only in that link - it is never transmitted to or stored on LevConfide's servers. Opening the link permanently deletes the secret, and any link left unopened expires automatically after 5 hours. No account is required for either side of the exchange.

Capabilities
What we deliver
- AES-256-GCM encryption performed entirely in the browser before anything is sent
- Decryption key lives only in the share link - never transmitted to or stored on the server
- One-time view: the secret is permanently deleted the moment it is opened
- Automatic 5-hour expiry for links that are never opened
- No account or sign-up required for sender or recipient
- Minimal server-side footprint - only encrypted ciphertext is held, and only until it is read or expires
Outcomes
Why it matters
- Keep temporary secrets out of durable chat history, inboxes, and Slack channels
- Reduce standing exposure from copied credentials, tokens, and private notes
- Give recipients a simple, single-use handoff with a built-in expiry
- Avoid retaining sensitive text longer than the moment it needs to exist
Approach
How it works
- 01Type the confidential text - it is encrypted locally, in the browser
- 02LevConfide generates a one-time link; the decryption key never leaves that link
- 03Share the link through any channel you already use
- 04The link self-destructs the instant it is opened, or after 5 hours if it never is
Frequently asked
Common questions
How long does a LevConfide secret last?
A secret is permanently deleted 5 hours after creation, or immediately after it is opened once - whichever happens first.
Can a secret be viewed more than once?
No. Once a secret link is opened, it is destroyed and cannot be viewed again by anyone, including the original sender.
Is the message encrypted?
Yes. Messages are encrypted with AES-256-GCM in the sender's browser before they are sent anywhere. The decryption key lives only in the link itself and is never transmitted to or stored on the server.
Does LevConfide keep a copy of what is shared?
No. The server only ever holds encrypted ciphertext until it is viewed or expires, and it is permanently removed at that point. There is no account, backup, or message log.
