Frequently asked questions
Can you read my secrets?
No. The secret is encrypted in your browser before it is sent, with a key that stays in the link, after the # sign. Browsers never send that part of the address to servers. We only receive an unreadable encrypted block.
Is it really free?
Yes, with no account, no ads and no time limit. A paid enterprise plan (white label, teams, SSO) will come later, without removing any free feature.
What happens after it is read?
The secret is deleted from our database in the same operation as the read. If someone opens the link again, they see the same message as for an unknown link.
What if Slack or Outlook opens the link before my recipient?
No risk. The link page does not contain the secret. It is only sent after a click on “Reveal”, which link previewers do not do.
Can the recipient keep a copy of the secret?
Yes, and no service can prevent it: once displayed, a secret can be copied, written down or photographed. Sésame Éclair guarantees that the link opens only once and that nothing remains on our side; it does not control what the recipient does afterwards. Only send secrets to people you trust.
