Radius
Parental consent
Print this page, sign it by hand, and photograph it in the Radius app — there is a button for it on the screen that sent you here. No envelope, no email to compose. Once somebody here has read it, you can add your child to your family.
This is one way to prove you are the parent. The second is a one-minute identity check in the app — a photo of your ID and a live selfie, handled by a specialist company that deletes the images within 30 days and never sends them to Radius. Either one is enough on its own, and both are free. There is a third, which applies only to people who are already paying: federal law counts a real charge to your own card as proof, because the statement reaches the cardholder. So if you have paid for a family plan on our website, that payment already stands as your verification and we do not ask you to do this as well. You never have to pay in order to verify.
A federal law — the Children's Online Privacy Protection Act, COPPA — says that before an app collects personal information from a child under 13, it must get consent from that child's parent, and must actually check that the person consenting is the parent. A child's location is named in the rule as exactly the kind of information it covers.
Radius could ask a child to tick a box. It would be quicker and it would be worthless: a child cannot give this consent, and a form that pretends otherwise is a form designed to be waved at a regulator rather than to protect anybody. So the parent signs, and this is the signature.
That Radius may collect and show your child's location to the people you — and only you — connect them with inside your family. Positions are kept 10 days and messages 14 days, then deleted automatically. Nothing about your child is sold, and there is no advertising in Radius at all. The full detail is in the acknowledgment and the privacy policy.
You can take it back at any time. Withdrawing consent stops the collecting immediately, and removing your child from your plan or deleting their account removes what is held.
Fill in every line. Print and sign by hand — a typed name here is not what makes this work.
Parent or guardian's full name: ______________________________________
Email address on the Radius account: __________________________________
Child's full name: ____________________________________________________
Child's date of birth: ________________________________________________
My relationship to the child: _________________________________________
I confirm that I am the parent or legal guardian of the child named above. I have read the acknowledgment and the privacy policy, and I consent to Radius collecting and sharing my child's location with the family members I choose. I understand I may withdraw this consent at any time.
Signature: ____________________________________________________________
Date: _________________________________________________________________
Easiest: in the Radius app, tap “Photograph the signed form”. It goes straight to us — nothing to attach, nothing to post.
If you would rather: email a photograph or scan to accounts@radiusfamily.com, or post it to Radius Family LLC, 3563 Hillside Road, Slinger, WI 53086.
We keep the form itself as the record of your consent, and nothing else from it. It is not published anywhere and cannot be fetched by a link.
How long we keep it. While your consent stands, the form is the reason your child's location may be collected, so it is kept. Once that consent ends — you withdraw it, they leave your family, or the account is deleted — it is kept for one more year and then deleted automatically, so that the period it covered can still be accounted for. A form sent by somebody who then never adds a child is deleted after 90 days: an unused signature is evidence of nothing.
The obvious design is a web form where you type your name and press Send. Radius already has that — it is the line you sign in the app when you set somebody up — and it is not what the law counts as verification.
When the FTC wrote the rule it deliberately left electronic and digital signatures out of the list of accepted methods, on the grounds that a typed or drawn signature on its own does not reliably show who agreed. Anyone can type a name. What it does accept is a form signed by hand and returned — and it explicitly allows that return to be an electronic scan, which is why the photograph works and the envelope is optional.
So the pen is the only part that has to happen off the screen. Everything else is three taps.
