Your data, briefly.
Cardr is built so you can be remembered without giving up your privacy. This page tells you exactly what we collect and why.
What we store about you
When you create a card, we save:
- Your card content — name, title, company, contact links, optional profile photo, chosen card style.
- Your private email — used only to send the magic edit link. Never published.
- Your URL slug — the public address of your card.
What we log when your card is viewed
For each scan of your public profile we record the timestamp, the visitor's User-Agent string, and the referrer URL. We do not log IP addresses, do not set tracking cookies, and do not share scan data with any third party.
What we collect when you exchange details
If a visitor sends you their details from your profile page, we relay their name, email, phone, and note to your private email. We do not retain that submission on our servers after the email is sent.
Third parties we use
- Resend — sends the magic edit-link email and exchange notifications.
- Stripe — processes subscription payments. We never see or store your card number.
- Apple Wallet — your
.pkpassfile is downloaded directly from us; Apple does not share telemetry back.
Cookies
We use one cookie: cardr_edit, a signed session token that proves you are the owner of your card while you edit it. There is no analytics cookie, no advertising cookie, and no third-party cookie.
Deleting your card
Email us and we will delete every record tied to your card — card content, photo, scan logs, edit tokens, and (if applicable) cancel any active subscription. Deletion is permanent.
Data location
Card data is stored in a single SQLite database on the server that runs Cardr. Photos are stored on the same machine.
