Chat keeps what you paste

If the chat is logged, the secret in the chat is logged. Use a burn link when the secret should not remain.

A chat transcript is a copy. The other person’s app, the provider, and sometimes a backup all can keep the text. Deleting your side does not delete theirs.

A one-time secret stores the text encrypted, shows it for a limited number of views, and then deletes it. The link is the capability. Anyone with the link can spend a view. Send the link on one channel. If the secret is a password for an account you also named in that message, you have described the target next to the key. Send the link alone, and name the account somewhere else, or not at all.

Check the view count you set. A link created for one view is spent by a link-preview bot if the chat client fetches URLs. When that happens, the recipient opens a link that is already gone. Turn off previews for that send, or set the view count with the preview in mind.

The tool does not expire a secret that you also pasted in the chat. The chat copy remains. The guide is one-time secrets. The tool is RookSecret.
