Frequently asked questions

Last updated: 22 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?

You can always add the other parent's phone number as a contact on the tap page, and two contacts are included free. A separate login for a second guardian, so you can both manage the profile independently, is part of CallKin Pluss. Each guardian chooses whether their own contact details show on the public tap page.

What happens if I delete my account?

Your guardian profile and any children 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 child 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?

CallKin ships to Norwegian addresses only for now. Ordering isn't open yet. Join the waitlist and we'll email you the moment bands are available.

Will the band fit my child's wrist?

The band comes in two adjustable sizes. The small one closes at roughly 125 to 175 mm around the wrist, and the large one at 160 to 230 mm. The ranges overlap, so choose by measurement rather than by age. Measure the wrist with a tape measure or a strip of paper before you order.

How much will it cost?

A CallKin band is 249 NOK, plus 49 NOK shipping anywhere in Norway. You buy the band once, and the contact page is provided for at least two years from the day you received the band. Everything the band needs to work is included, with no subscription. CallKin Pluss is an optional extra, described below. Join the waitlist and we'll email you the moment bands are available to order.

What is CallKin Pluss?

An optional subscription that adds extra features to a child's profile: more contacts on the tap page, a login for a second guardian, a text message alert when a band in lost mode is scanned, scan history, and a contact that expires by itself, for travelling. One subscription covers every child on your account. The band works fully without it, and you never need it for someone to reach you when they scan a band.

Is this GDPR compliant?

Yes, and here is what that means concretely. We collect only what the product needs to function, and you can access, export, or delete your information at any time. We never sell your data, and never share it with advertisers. To run the service we use a small number of processors, including our database and email providers. All of them are named in our privacy policy, along with the legal bases, retention periods, and transfers outside the EEA.

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.

Someone added my number to a CallKin band. What does that mean?

It means a parent or guardian listed you as an emergency contact for their child, and we got your name and number from them rather than from you. Your name and number are shown to anyone who scans that child's band, without logging in, so that a stranger who finds the child can reach an adult quickly. They are not used for anything else: no marketing, no profiling, no selling or sharing. The quickest way to be removed is to ask the parent, who can delete you at any time and it takes effect immediately. You can also contact us at support@callkin.co to see what we hold, correct it, have it deleted, or object to it. The full explanation is in the “If your number is on a CallKin band” section of our privacy policy.
