Questions

If yours is not here, send me an email and I will add it.

Windows says the file is unsafe. Is it?: Windows shows that for any app without a paid code-signing certificate, which this one does not have. It is not a judgement about the file itself - we just don't have $500 to pay for the certificate.
Does it need my Discord password or token?: No. It never asks you to log in and never sends anything anywhere.
Can I undo it?: Yes. Reinstalling Discord puts everything back the way it was.
Nothing happened when I ran it.: Discord was probably still running in the background. Right-click its icon in the system tray, choose Quit, then run the app again.
Is there a Mac or Linux version?: Not right now. Windows only.
Does it cost anything?: No. It is free, and there is nothing to buy inside it.
