Frequently asked questions

Last updated: 7 September 2026

Is my child's information safe if the wristband is lost or stolen?

Yes. The wristband itself stores nothing, only a randomly generated web address. Whoever finds it and scans it sees just the name and contact details you've chosen to share, the same page you could show a stranger yourself. There's no way to look up your child's information without that specific band.

What information does the wristband itself store?

Nothing personal. Each band stores a single unique web address (a secure, unguessable token), the same way a QR code on a poster stores a link and not the poster's actual content. Names, phone numbers, and any other information live in our database, not on the band, and are only shown to someone who scans it.

What happens if my phone breaks or I switch phones?

Nothing changes for the band. Your contact information lives in your CallKin account, not on your phone, so you can log in from any device to check or update it. The band itself doesn't need your phone at all, it's scanned by whoever finds it, using their phone.

Can I edit or remove the information later?

Yes, at any time, from your dashboard. You can update your name and phone number, change what's visible on the tap page, or unlink a band entirely.

Can a second parent or guardian access the same profile?

Yes. You can invite a second guardian to a dependent's profile by email. Both guardians can manage the profile independently, and each one can choose whether their own contact details show on the public tap page.

What happens if I delete my account?

Your guardian profile and any dependents only you guard are removed immediately from our live systems. An encrypted backup copy may persist for up to 30 days afterward as part of our routine backup rotation, then it's permanently deleted too. If a dependent has a second guardian, their profile stays with that guardian instead of being deleted. You can export a copy of everything we store about you before deleting, from your dashboard.

Is CallKin available where I live?

Not yet. Our first batch is on its way and clearing customs, and we'll open ordering as soon as it arrives. CallKin ships to Norwegian addresses only for now. Join the waitlist and we'll email you the moment bands are available.

How much will it cost?

A CallKin band is 229 NOK. You buy the band once, no subscription required. Join the waitlist and we'll email you the moment bands are available to order.

Is this GDPR compliant?

Yes. We collect only what the product needs to function, never sell or share your data, and you can access, export, or delete your information at any time. See our privacy policy for the full details.

How do I dispose of the wristband when I no longer need it?

The wristband contains a passive NFC chip and must be disposed of as electrical waste. It must not be thrown away with ordinary household waste. You can hand it in free of charge at shops that sell similar products, or at your municipal collection point for electrical waste. Use sortere.no to find the nearest one. Take-back is always free. The chip holds no personal information, only a web address, but we still recommend removing the band from your account before handing it in.
