Is NullPaste really anonymous?

Yes. There are no accounts and no sign-up. We don't run analytics or third-party trackers, and raw IP addresses are never stored — rate limiting uses a hashed (HMAC-SHA256) identifier instead.

How long does a paste last?

You choose: 10 minutes, 1 hour, 1 day, 1 week, or never. Timed pastes are deleted automatically once they expire. You can also enable burn-after-read so the paste is destroyed after a single view.

What is burn-after-read?

A burn-after-read paste is deleted permanently the first time it is opened. It's useful for one-time secrets or links you only want a single person to see.

Can I password-protect a paste?

Yes. Add an optional password and only people who know it can open the paste. Passwords are hashed with Argon2 on the server. For stronger privacy, enable end-to-end encryption, which encrypts the content in your browser and keeps the key only in the share link.

How do I delete a paste?

Timed and burn-after-read pastes disappear on their own. Pastes set to never expire come with a one-time delete code shown right after creation — save it, then use it to remove the paste whenever you like.

What can I paste, and how large can it be?

Any plain text or source code, up to 1 MB per paste. Code is shown with Shiki syntax highlighting and the language is auto-detected, or you can set it yourself.

How do I create a temporary paste that auto-deletes?
