Contact
A question, a price that looks wrong or a card that is missing: here is how to reach us.
By email
Always available, no account needed.
If it is about a card or a price, include the card number, in the form 168/191. Then we do not have to guess which of the dozens of versions you mean.
From the app
If you have an account this is the easiest route: your question stays attached to your account, and we can see what is in your collection. Go to Account and then Help.
What to expect from us
Cardtracker is made by one person, so there is no support team behind it. A reply usually takes a few working days. If a price is really off, I would rather hear it today than next month: reports like that are how the catalogue gets better.
Security
If you think you found a security issue, report it at the address in security.txt, so it lands in the right place straight away.
