What we store, and what we don’t.

What we actually keep

• A random identifier. On your first visit we set an HTTP-only cookie called wp_uid containing a random string. It identifies your saved work and nothing else. It is not linked to your name, your device or any advertising profile.
• The figures you type in. Which cards you selected, the rough monthly spending you entered, which credits you ticked off, and your reset-date settings. This is stored against the random identifier so it survives closing the tab.
• Your email address, only if you ask for reminders. It is used to send the credit reminders you requested and nothing else. Every message carries a one-click unsubscribe, and unsubscribing deletes the address.

What we never collect

No bank or card credentials. No account numbers. No transaction history. No advertising or cross-site tracking pixels. No fingerprinting. We have no affiliate relationships, so there is no commercial reason for us to track where you go next — and we don’t.

Where it lives

Your saved work is held in Cloudflare Workers KV and expires automatically after a year of inactivity. A copy is also kept in your own browser’s local storage so the tools work instantly and keep working if the network drops.

Deleting it

Open the analyzer and use Reset everything and start over. That erases the server copy and the browser copy immediately. Clearing your cookies also orphans the server record, which then expires on its own. There is no recovery process, because there is no account to recover.

One honest caveat

Because identity is just a cookie, anyone using the same browser profile sees the same saved wallet. Treat it as a convenience, not a private vault. Nothing stored here is sensitive on its own — it is a list of card names and some round numbers — but it is worth knowing.
