Dirac — Privacy Policy

Who Operates It

Dirac is operated by David Monaghan on hardware he owns. It is a personal assistant in a small number of private servers, not a hosted service. There is no company behind it and no staff with access to it.

Information We Collect

Dirac reads the following, and nothing else:

• Messages in channels that were opted in. A channel is added to an allow list by the operator, from his own terminal. Dirac cannot read a channel that is not on that list.
• Direct messages from allowed accounts. A direct message from any other account is dropped rather than answered. The account name, the account ID, and the text are written to a local log so that the operator can see who tried, and the sender is told nothing.
• Speech in voice channels that Dirac has joined. Audio is converted to text so that the application can answer. Only accounts with a role are transcribed; others are noted as present and not transcribed.
• Attachment names, types, and sizes. The file itself is downloaded only when the operator asks for it.

Each of these carries the Discord account ID, the display name, the channel, and a timestamp, because that is what identifies who said what and where.

Dirac does not read message history it was not sent, does not collect your email address or payment details, and has no advertising or analytics of any kind.

How Information Is Used

Your message is used to produce an answer, and for no other purpose. To do that it is sent to a large language model. That model is operated by Anthropic and runs on Anthropic's systems, under their terms. Speech to text and some short replies run locally on the operator's machine and go nowhere.

Content is also written to local logs so that the operator can see what his own machine did. That includes security events, such as a message that was dropped, or an action that was refused.

Information Sharing

Nothing is sold, rented, or given to advertisers. The only third party that receives message content is the model provider named above, and only to produce the answer you asked for.

Discord itself holds your messages under Discord's privacy policy, whether Dirac is present or not.

Data Retention

Logs and transcripts are kept on the operator's own machine. They are kept for as long as they are useful and are not published. They are backed up with the rest of that machine, to storage the operator controls.

Data Security

The machine is encrypted at rest and the logs are readable only by the operator's account. No claim is made that this is more than one careful person's setup, because it is not.

Your Rights

You can ask what has been recorded about you, and you can ask for it to be erased. Use the contact form and say which Discord account you are. Erasure is done on request and is not conditional.

You can also stop the collection yourself: leave the channel, or ask the server owner to remove the application.

Children

Discord requires its users to be 13 or older, and Dirac is only in adult private servers. It is not directed at children and does not knowingly record information from them.

Changes to This Policy

This policy can change. The date at the top says when it last did.

Contact

Questions, and requests to see or erase what was recorded, go through the contact form. The rules for using the application are in the terms of service.
