Email support@aphexcoding.tech. That is the only channel — there is no ticket portal to register for and no chatbot in front of it.
Response time: we aim to reply within one business day (Central European Time),
and always within three. Security reports are looked at the same day — put
SECURITY in the subject.
Please do not send us data you would not want to leave your instance — we do not need it. The app has no backend, so we cannot look anything up on your behalf.
The full list of known limits is in the documentation.
Billing, invoices and licence terms are handled by Atlassian — the app is sold paid via Atlassian. For anything about a subscription, start in your Atlassian administration; for anything about how the app behaves under a licence, write to us.
Without an active licence the app switches to read-only: the log and proof export keep working, so your audit data is never held hostage.
