For staff
Creating a secret needs a work account. Open the sender app — you will be asked to sign in.
You were sent a link
Open it directly. A secret link looks like
/s/A7K2QM#… and the part after the # is the key itself.
It never reaches this server, so the link must be used exactly as you received it —
copy the whole thing, including everything after the #.
If your link stops at the #, ask the sender for a new one. There is no
way to recover the missing part: this service never had it.
How it works
The secret is encrypted in the sender's browser and decrypted in the recipient's. The key is split: half travels in the link, half is held here and released only once every condition the sender set has been met. Deleting our half makes the stored ciphertext permanently unreadable — which is what happens when a secret expires, runs out of views, or is deleted.
What this does not protect against: anyone who obtains the complete link before the secret is opened. Treat the link as the secret, and if it matters, ask the sender to add a password and send it through a different channel.
