Track your cards without storing the numbers
CardIndexer is built so there's nothing sensitive to leak. We keep just enough to recognise a card — and nothing more.
What we store
- • A label you choose (e.g. “Ops Visa”)
- • Card brand (Visa, Mastercard…)
- • Last 4 digits
- • Expiry month/year
- • Where and when a card was used
What we never store
- • Full card numbers (PAN)
- • CVV / security codes
- • PINs or passwords
- • Your card credentials on merchant sites
Security fundamentals
Encrypted in transit
All traffic between the extension, your dashboard, and our servers is protected with TLS.
Minimal data by design
We can't lose what we don't hold. No full numbers means a breach exposes nothing usable to charge your card.
Isolated per account
Your data is scoped to your account or organisation. Team members only see what their role allows.
Payments via Stripe
Billing is handled by Stripe. We never see or store your payment method for your subscription.
Your data, exportable
Export everything you've stored to CSV or JSON at any time.
Deletion on request
Close your account and your data is removed. Contact us anytime for a data request.
