Cardkeep

Every gift card you own, with the balance that's actually left on it

Add your gift cards and store credit, log what you spend, and Cardkeep counts the balance down for you — plus a running total of the free money you're sitting on and a warning before a card lapses. Free, no install, nothing leaves your browser.

Stored in your browser only. Nothing you do in the web version is sent to our servers. Clear your browser data and it's gone — so export a backup from the in-app menu if you want to keep it.

What you can do in Cardkeep on the web

1

A real card face per store

Each card gets its own gradient card face with the store, the number (masked until you reveal it) and the balance in big figures — readable at the register.

2

Log a spend, balance updates

Enter what you used with a live 'balance after' preview that refuses to go past what's on the card; the spend lands in a dated history you can undo.

3

Expiry warnings before money lapses

Set an expiry per card and choose your warning window (7–120 days). Cards inside it move to Needs attention, and expired balances drop out of your total.

4

Total value across the whole wallet

One hero number for the usable balance, plus what's expiring soon, what you've spent, and what has already lapsed.

5

Balance by store and spending trend

A donut of where your remaining balance sits, six months of spending bars, and a 'never touched' list led by your biggest unused card.

6

Yours only, exportable

Card numbers and PINs stay in this browser. Export a JSON backup or a CSV of every balance whenever you like.

Do I need an account?+

No. Open Cardkeep and start using it right away. Sign in with Google only if you want to upvote an app, save it to your list, or leave a comment.

Where is my data stored?+

Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.

Is there a Cardkeep app for iPhone or Android?+

Not yet. Cardkeep is a community proposal: the browser version is complete, and we build the iPhone and Android app once 100 people upvote it. Upvoters get one email when it ships.
