Share secrets that
delete themselves
Encrypted in your browser, sent as a single-use link, and destroyed the moment it is opened.
Built to carry the secrets
you shouldn’t keep
A password pasted into Slack or email never really leaves. It sits in the thread, gets forwarded, and turns up again in a search months later.
Hider gives it a lifespan instead. Send the link, and once it is opened — or the clock runs out — there is nothing left to find.
Built for the handovers
that shouldn’t linger
Passwords & logins
Hand a client or contractor their credentials without leaving a copy in chat.
Keys & recovery codes
API keys, database credentials and recovery codes, shared once and gone.
Private notes
Anything that should not outlive the moment you needed to send it.
Three steps,
no setup, no account
Paste your secret, say when it should expire, and send the link that comes back. Nothing to install, and nothing left behind.
Nothing more to do
There is no password to save and no key to send separately — closing the tab afterward is enough.
Ask your assistant
it never even sees the link
Connect ChatGPT or Claude and ask for it directly — “send Jane the staging password, one read only.” It emails Jane a one-time link straight away — the assistant only ever sees a confirmation, never the link and never the secret.
Email was never built
to forget anything
A password dropped into an email joins every backup, every forwarded copy, and every year that inbox stays open. Nothing about it expires, and nothing tells you whether it has already been read.
A link is different. Once it has been opened, or its time is up, there is no inbox left holding a copy.
- Sits in the thread indefinitely
- Forwarded and CC’d without a trace
- No way to know it was read
Hider
- Opens once, for one person
- Expires on its own if nobody does
- Gone the moment it is read
Send it once. Then let it disappear.
Free to try, no account needed. One link, one read, gone for good.
