Sendlock turns any password or secret into a link that expires after a single view or a time you set — so sensitive info never sits around in chat or email. Try the live demo on the right.
No accounts for recipients, no secrets left behind in chat logs.
Drop in a password, API key, note, or file. Sendlock encrypts it before it ever leaves your browser.
Choose one view or a time limit, and add a passphrase if you want a second layer of protection.
Share the one-time link anywhere. Once it's opened or expires, the secret is destroyed for good.
Stop pasting passwords into chat — share them the right way.
Links expire after one view or a time you choose, so nothing lingers where it shouldn't.
Secrets are encrypted in your browser, so only the recipient can ever read them.
Share passwords, notes, API keys, or files up to your plan's limit — all the same way.
Add a passphrase so even someone with the link needs an extra key to open it.
Get notified the moment your secret is opened, so you know it reached the right person.
Once viewed or expired, the secret is permanently deleted from our servers.
Simple plans with no hidden fees. Cancel anytime.
You create a link to your secret and set it to expire after one view or a set time. Once it's opened or the time runs out, the secret is deleted and the link stops working.
No. Anyone with the link can open the secret in their browser — no account, app, or signup required.
Yes. Share files as well as text secrets, with size limits depending on your plan — all sent through the same expiring links.
The demo is for illustration only — it stores your secret locally in your browser and isn't encrypted. The real product encrypts secrets and deletes them after viewing.
Yes. The Free plan includes unlimited text secrets and files up to 5 MB. Upgrade to Pro for larger files, passphrase protection, and view notifications.
