Know where your money goes — automatically
Forgotten free trials, that gym app you never use, the card you saved on a dozen sites — CardIndexer keeps a live map of it all, without you lifting a finger.

Stop the subscription creep
Catch every subscription
Every recurring charge is flagged the moment it happens, so you can spot the ones you forgot you were paying for.
See where your card lives
A running list of every site your card is saved on — handy when you lose a card or just want to clean house.
Never miss a renewal
Get a nudge before a subscription renews or a card expires, so you can cancel or update in time.
Private by design
We only keep the last 4 and expiry — never the full number. Nothing sensitive to lose.
Zero busywork
No spreadsheet to maintain. It updates itself as you shop.
Free to start
Track your first card free, forever. Go unlimited with Pro when you're ready.
Find your forgotten subscriptions
Add the extension and CardIndexer starts mapping your cards from your very next purchase.
