Children's privacy
This is the notice federal law (COPPA) requires us to show you, the parent or guardian, before a child under 13 uses Radius. It's short because what Radius collects is short. The app will point you back here before you're asked to consent.
This summary is here to help. It isn't part of the children's privacy notice. The full text below is what counts.
The same things as any member, and nothing extra: their position (with speed and battery) while sharing is on; the name and photo you set on their profile; the messages they send to people on the family plan; which named family places they are at, so "arrived at Home" can be noticed; which device is theirs; the phone's step counter, used only to tell walking from driving and to measure a walk, never to work out anything about their health; and, if the app crashes or a request fails, a diagnostic report naming the fault, the app version, the phone model and the account, kept 90 days. No advertising identifiers, no third-party analytics, no tracking libraries — the app contains none, for anybody.
Showing their location to the family you connected them with, delivering their messages, and the safety alerts you turn on. Nothing else. A child's information is never sold, never shared for any commercial purpose in any form, and never used for advertising — the same promise the privacy policy makes for every member, kept by the same code.
The people on your family plan whom you, the manager, have connected with the child — that is the product. The only outside services in the path are the ones that carry it (named, with exactly what each sees, in the privacy policy): none of them is told who is a child, and none receives a child's position tied to a name.
Positions 10 days, messages 14 days, the account until you delete it — children's data is kept no longer than anybody else's, and there is no longer tier. Your consent record itself is kept, because the law that requires the consent requires the record.
A child may install Radius and accept a family invitation, but nothing is collected from them until a verified parent consents — and only the family's managing parent can give that consent — consent is given from that parent's own signed-in account, for a named child who reaches the plan by a code only the parent holds.
Nothing is collected until that parent has been checked — consent alone is not enough, and the signature is not even offered until the check is done. It is an identity check in the app, which takes about a minute: you photograph your government ID, then look into the camera while a short video is recorded. A specialist company checks that the document is genuine and that the face is yours — the video is how a living person is told apart from somebody holding up a photograph. This is the FTC's face-match-to-photo-ID method. Radius never receives or stores those images. They go to the company doing the checking, which deletes them within 30 days; what comes back to us is that it passed, when, and a reference — never your ID, never your photograph. That company is named, with exactly what it sees, in the privacy policy.
It costs you nothing. If you would rather not photograph an ID at all, there is a second way: the printed consent form, signed by hand and sent back to us. Write to us and we will set it up. Both are free, and you never have to pay in order to verify.
There is a third method, and it is worth stating plainly rather than leaving as a surprise in a record. The FTC's rules count a real charge to your own card as proof of parenthood, because the statement reaches the cardholder — somebody who is not you cannot quietly use your card without you seeing the line. So if you have already paid for a family plan on our website, that payment stands as your verification and we do not ask you to do an ID check as well. It has to be a payment that actually took money: a free trial, a failed charge and a fully discounted plan all verify nothing. Every consent record states plainly which of the three backs it, and when.
At any time you can see what is held about your child (open the app — the product is the disclosure: their map, their places, their history are all visible to you), delete it (delete their account from Settings, which removes their messages, photos, history and places from the server's disk), or withdraw consent — from the child's page in the app, or by writing to us — which stops collection immediately while keeping the record that consent existed and was withdrawn. Withdrawing does not need a reason and does not affect the rest of the family.
One thing keeps working after you withdraw, deliberately: the SOS button. If your child presses it, their family is still alarmed and the emergency contacts you listed are still texted — and that message still names them and the last place we knew them to be near, even though nothing new is being recorded about them. We think a withdrawn consent should stop us collecting, not stop a child being able to call for help, and we would rather write that exception down than have you find it out. If you want that to stop too, delete the account: that removes the history such an alert would draw on.
Sharing is never silent: a permanent notification sits on the child's phone the whole time their location is shared, and the app has no way to switch it off, in words a child can read. Radius does not do covert monitoring of children, because a child who knows is the design.
