CIRQL is the living address book where you own your entry. Update your contact info once — everyone you trust gets the update instantly.
No spam. Unsubscribe anytime. We take privacy seriously — it's kind of our whole thing.
Why CIRQL
Change your number, address, or email once. Everyone who has permission gets the update instantly. No broadcasting. No chasing.
Grant access to specific contacts, set what they can see, and revoke it anytime. Your identity, your rules.
CIRQL is federated — no single company owns your identity. Your information lives with you, not in a corporate database.
Think of it as your contact card, permanently live. Share your CIRQL link and your contacts stay current — forever.
How it works
Add your phone, email, and address to your CIRQL profile. This is your one source of truth.
Invite trusted contacts to follow your identity. You control exactly what each person can see.
When your details change, everyone you've given permission receives the update automatically.
About CIRQL
CIRQL is a federated identity network built on a simple idea: your contact information should travel with you. When you change your phone number, move to a new address, or get a new email, the people you trust should know — automatically.
No announcements, no emails to send, no spreadsheets to update. Built for people who are tired of being out of date.
We're building in the open. Drop your email and we'll send you a launch invite — no spam, no noise, just the thing you actually asked for.
No spam. Unsubscribe anytime. We take privacy seriously — it's kind of our whole thing.
For developers
CARDO is the enterprise API for the CIRQL identity network. If your product needs accurate, consent-driven contact data at scale — addresses, phone numbers, emails, in real time — CARDO gives you a single programmable connection to the network.
One API. Always current. Always permissioned.
