Chat: in the app, open the account menu (bottom of the sidebar, or More on a phone) and choose Help & support. On the sign-in page, use Chat with us. Leave your email and we'll reply there if you've moved on.
Email: [email protected].
Help centre: help.justonce.ai — you're here.
We're a small team in Australia. Chat is answered during business hours (Mon–Fri, Sydney time) and email within one business day.
What to include
the AI tool you use (Claude, ChatGPT, Cursor…) and the account email;
roughly when it happened, with your timezone;
what you asked or clicked, and what you saw — a screenshot helps.
Please don't paste memory content or documents into chat unless we ask; we can look things up with your account email and a timestamp. Security reports: [email protected] with "Security" in the subject.
