Privacy
Here's how CardBird manages your private data. Updated 17 October 2026.
What we store
- Your account: your name and email, and your password in a scrambled form we cannot read back. If you sign in with Google or Apple, we keep the account they tell us about.
- Your cards: the people you add or import, every fact on them, and their photos.
- A history of what changed on your cards.
- A cookie that keeps you signed in.
- If you joined the waitlist: your email address.
We do not sell your data. Apart from what this page describes, your cards stay private to you.
Looking up public profiles
CardBird can fill in your contacts from what they have published about themselves. This is on until you turn off Look up public profiles for my contacts on your account page. Nothing it finds is added until you choose Add.
Perspex
Perspex lets people share their own contact details and keep them up to date.
- Your account. When you sign up, we create your Perspex account with your email address. The facts on your own card are kept in step with your Perspex profile.
- Offers. When a contact card has an email address, we offer the card through Perspex to whoever owns that address. The offer carries your name and account email, so they know who it is from, and the card's contact facts. Your notes, tags, related people or identification numbers are never shared.
- Links. If they accept, they choose what to share with you, and their card stays up to date. If they stop sharing, what they shared is removed from your card.
- If the card's email changes, the old offer is withdrawn. Deleting the card or closing your account withdraws it too.
Agents
If you connect an agent such as Claude on your account page, it can read your cards. If you allow it, it can also add and change facts and make new cards. It can never delete or merge a card, and never sees identification numbers. What it reads goes to that agent's provider. You can remove its access at any time.
Exporting or deleting your data
- Export some or all of your cards at any time, as a vCard (.vcf) file that other address books can open.
- Delete a card, and it is gone with its facts and photos.
- Close account on your account page deletes your account, every card and fact, and every photo. It also unlinks your Perspex account and withdraws any open offers.
