Report a bug

Tell us what went wrong. If it could let someone read, change or block what they shouldn't, use Report a security issue instead.

We reply by direct message in OpenArcanum, so we need your contact code. An e-mail address is optional.

One line: what is wrong, and where.

Plain text only. Leave out passphrases, keys and anyone's private messages.

1, 2, 3… as exactly as you can.

For example "0.1.0, Windows 11".

How we reach you

In the OpenArcanum app (desktop or in your browser), open Direct messages → Contacts → Your contact code and copy it. It lets us message you without sharing a community, and works for about a week. A name in it is optional.

The anti-spam check needs JavaScript; it runs in your browser and sends nothing anywhere.

We keep reports encrypted on our server and use what you send only to handle your report.
