Never lose track of where your cards are stored and charged.
Find forgotten subscriptions, know which sites have your card saved, and get a heads-up before a card expires — all captured automatically as you check out.
- Automatically catches subscriptions and one-off buys
- See every site your card is saved on
- Free for your first card — no credit card needed
No full card numbers, ever — only label, brand & last 4.
Spreadsheets and email searches can't keep up
Most people track cards by hand — a spreadsheet they forget to update, or digging through receipts in their inbox. CardIndexer does it for you, automatically, and keeps it organised.
Spreadsheets & inbox
- Only as current as the last time you remembered to update it
- No idea which charges are recurring until the money's gone
- Reissuing a card means guessing every place it's saved
- Sensitive numbers end up pasted into a sheet
CardIndexer
- Updates itself every time you check out — nothing to maintain
- Flags subscriptions vs one-off buys as they happen
- One reissue checklist shows every site to update
- Stores only label, brand, last 4 & expiry — never full numbers

Card tracking that runs itself
From the moment you check out to the day you reissue a card, CardIndexer keeps the whole picture up to date.
Automatic detection
A lightweight extension recognises checkout and receipt pages and captures the payment — no manual entry, with an undo window so you stay in control.
Subscription vs one-off
Knows the difference between a recurring charge and a single purchase, and records the billing interval so renewals never surprise you.
Expiry & renewal alerts
Get a heads-up before a card expires or a subscription renews, so you can update or cancel in time.
Which sites have my card
Logs every payment page you reach so you can see exactly where a card may be saved — even when no charge went through.
Reissue & offboarding checklist
When a card is lost, reissued, or an employee leaves, get a ready-made list of every place to update.
Export & audit
Export everything to CSV or JSON, and (on team plans) see a full audit log of who changed what.
Take back control of your subscriptions
Rediscover forgotten trials, see every site holding your card, and never get blindsided by a renewal. Start free with one card.
One source of truth for company cards
Shared cards, roles and permissions, an audit log, and a reissue checklist for offboarding — so a lost or reissued card is a checklist, not a scramble.
We track your cards without ever storing the numbers
CardIndexer only keeps what's needed to recognise a card: a label you choose, the brand, the last 4 digits, and the expiry. No full numbers, no CVV, no PIN — so there's nothing sensitive to leak.
Set up once, then forget about it

CardIndexer spots the payment, asks which card (or auto-saves), and tags it as recurring or one-off.

Questions, answered
No. CardIndexer never stores a full card number, CVV, or PIN. We only keep what you need to recognise a card — a label you choose, the brand, the last 4 digits, and the expiry. That's it.
