Security
Radius runs behind Cloudflare, the network that protects a huge share of the web. Major banks, governments and tech companies rely on the same protection. Every connection is encrypted and filtered at Cloudflare's edge, and our server's real address is never exposed, so nobody can attack it directly.
This website counts visits with Cloudflare's analytics. It's cookieless, it doesn't fingerprint your browser, and it doesn't follow you to any other site. That's all! No advertising, no ad networks, no data brokers, and no tracking inside the app. The one thing the app does send is a report when it crashes or a request fails. It includes the device model, the OS version and which account it was, so we can fix the problem. Never your location or your messages.
Your messages and locations are stored on Radius's servers. That's how a message reaches someone whose phone is off, and how the map has something to show you. Everything is deleted on a schedule: locations after 10 days, messages after 14. You can also delete all of it whenever you like. Want to keep a conversation longer? That's up to you, and it's saved on your own device or in your own Google Drive.
Calls are never recorded. They go directly between phones when the network allows. When it doesn't, they pass through Radius's own relay servers on the way, and nothing is kept there either.
A few things come from outside Radius, and we want you to know exactly what they are. To show you a map, the Android app draws Google Maps, the iPhone app draws Apple Maps, and the web app draws Radius's own copy of OpenStreetMap. Those are just the map tiles. Finding where a phone is at all uses location services built into the phone. To find severe weather alerts, our server asks weather.gov about a person's location. Photos and videos sent in chat, and profile pictures, are stored with Cloudflare R2. A parent's ID check goes through Didit.
Your family's positions stay on Radius's servers. We never sell them, never give them to a data broker, and never use them to target ads. There are no ads here at all!
Share where I am links can't be guessed, and search engines don't index them. Whoever opens one sees your name and one point: where you are right now, and when. They never see where you've been or anyone else in your family. Every link ends on its own, after 8 hours at most.
What we store
Every location app stores your location. It has to, or there'd be nothing to show your family. What matters is what's kept, for how long, and who else gets it. Here's our complete list.
| What | Kept for | Then |
|---|---|---|
| Where you are and where you've been, including SOS events, flights and “watch me” records | 10 days | Deleted automatically |
| Drive summaries: miles, top speed, speeding and braking events | 14 days | Deleted automatically |
| Messages | 14 days | Deleted automatically |
| Photos and videos sent in chat, stored with Cloudflare R2 | 14 days by default | Deleted automatically |
| Who looked at your card or your history | 90 days | Deleted automatically |
| Crash and problem reports (device model, OS version, account; never location or messages) | 90 days | Deleted automatically |
| An ID check that was started and not finished | 30 days | Deleted automatically |
| A “Share where I am” link | 8 hours at most | Stops working when it ends |
| Your account: name, sign-in address, photo | Until you delete it | Gone the moment you do |
| Record of any admin access to your data | 90 days | Not offered |
| A signed parental consent form, where one was sent | While the consent stands, then 1 year | Deleted automatically; 90 days if never used |
| Your calls | Never recorded | Directly between phones when the network allows; otherwise through Radius's own relay servers, which pass them on and keep nothing |
| What the map shows you | Never recorded | Positions and routing stay on Radius's servers in the United States; map tiles are Google Maps on Android, Apple Maps on iPhone, and Radius's own OpenStreetMap in the web app |
Open a conversation and tap Keep. Every message is saved on your own device as it arrives, so you'll still have the whole thread after our server deletes it. Nobody but you can read that copy. Want it to survive losing your phone? Move it to your own Google Drive instead, and your phone gets the space back. Pick whichever you like. It's your choice, on your device.
One button in Settings removes your messages and photos, your location history, your places and every connection. The files come right off the server's disk, so nothing is left hidden in a database. It asks you twice, because there's no undo.
Private from day one
Every feature, no ads, and your family's data never sold. Your first 30 days are free, so there's nothing to lose.
