Questions
Will error pages ever go behind a paywall?
No. Every error page, fix, comparison and guide stays free and indexable. Pro only pays for the costly extras.
What counts as an AI diagnosis?
Only a decoder run on a trace that matches no known error and hasn’t been diagnosed before. Known errors and cached diagnoses are free.
Can I cancel anytime?
Yes, from the billing portal. You keep Pro until the end of the period you paid for, then move to Free. Saved errors stay.
What happens to my traces?
Secrets, emails and IPs are scrubbed in your browser before upload and again on the server. Pro keeps your decode history for 30 days.
Do you offer team plans?
Not yet. Pro is per person.
