Email keys@cardful.xyz and a person will read it. Most things are answered the same day.
Licence keys
It hasn't arrived. Check spam first — it comes from keys@cardful.xyz with
the subject "Your Cardful Pro licence key". If it is not there ten minutes
after paying, email us with the address you paid with and we will reissue it.
Nothing is lost; a key can be minted again at any time.
It won't paste. Open the popup, go to Plan, choose I have a licence
key and paste the whole string including the CARDFUL- at the front. Extra
spaces are fine. If it is refused, forward us the email and we will look.
New computer. Paste the same key again, from the same email. There is no device limit and no account to sign in to.
Renewal. Stripe charges the card once a year and a fresh key is emailed the same day. The new key is valid before the old one lapses, so there is no gap — paste it when it arrives.
Billing
Cancel: email us and we will stop the renewal. The year you have paid for runs to its end.
Refund: ask within 30 days of a charge and we will refund it. No reason needed.
Wrong email on the order. Tell us both addresses and we will resend.
The extension
A rate looks wrong. Tell us the card and the category. Rates are traced to a published issuer benefit rather than guessed, so a wrong one is a bug we want to fix — and every card shows when it was last confirmed.
A store is categorised wrong. You can fix it yourself: change the category in the popup or the overlay and it is remembered for that site. Tell us too and we will fix it for everybody.
A scan of my bank's offers page found nothing. Banks redesign their pages and the scanner has to be updated when they do. A scan that cannot read the page says so and changes nothing in your vault, rather than quietly emptying it. Let us know which bank.
Sync. If you have lost every device and did not save your pairing code, we cannot recover your vault — the key was only ever on your machines. Sorry. Your cards can be re-entered; the extension will not have lost your offers on any device that is still signed in.
Privacy and security
Read the privacy policy for what is stored and what is sent. If you believe you have found a security problem, email us with the details and we will respond quickly. Please do not post it publicly before we have had a chance to fix it.
