            Photos and text save automatically — changes are yours to tweak, the chip confirms each one.

            Your photo is only shown to users you have added and who have added you back — unfriending hides it both ways immediately.

            Badges

            No badges earned yet — badges come from being early, being first, and supporting the platform.

            Tap a badge to wear it next to your name.

            Identity verification

            Not Verified

            A photo of your ID is shown only to the service admin, so a human can confirm the account belongs to a real person. Once reviewed it is deleted. While unverified, your name carries a red notice to your contacts — verifying a contact's safety number is separate and remains your own check.

            Verifying and trusting is capped per day and per week to keep vouching real — the caps count attempts, undoing does not refund.

            Everyone you added or blocked. Blocking severs the relation both ways and stops their messages cold — nothing is restored by unblocking.

            No matches — or nothing to show for the current filters.

            Only approve YOUR OWN device. Nobody else ever needs to add a device to your account — whoever approves this code can read your messages and sign in as you. If you did not start pairing a device just now, cancel.

            Message

              You and your contact must see the SAME number — it is derived from both accounts' identity keys. Compare it over any other channel; a match proves no one is intercepting this conversation.
