smart.router watches a router so a household or a business does not have to. This page says exactly what that means, in the order that matters: what leaves your premises, who can see it, and what we will not do.

Last updated 10 October 2026.

What the router sends us

Which internet connections exist, whether each one is working, and which one is currently carrying traffic.
The public address each connection presents to the internet, so the app can show you the address your provider actually gave you.
How much traffic each connection has carried, as running counters. Volume only.
The router's own health: model, software version, processor load, memory, uptime, temperature, and its clock.
With the LAN package switched on, an inventory of the devices on your network: name, hardware address, address on your network, and whether each is online.

What it never sends

Not the contents of your traffic. We do not inspect, capture, proxy, store or read what you send or receive. There is no packet capture and no traffic mirroring.
Not the sites you visit. No browsing history, no DNS query log, no per-site record.
Not your credentials. The service holds no password for your router. It cannot log in to it. The router asks us what to do; we never reach in.

The network test in the app

Anybody can run "Test my network" in the app, with no account and no smart.router. It says whether a slow connection is your WiFi or your internet line. Here is everything it does.

What your phone does by itself. It finds the router your phone is connected to, asks that router for its name, and times small test messages to the router and to a few public servers on the internet. To reach your router, the iPhone asks you for the "Local Network" permission. The app talks to the router your phone is already using and to no other device on your network.
Who your provider is. Our service sees the public address your request arrives from, as every website does. It asks a public internet registry which provider that network belongs to (it asks about the network, not your own address) and sends the name back to your phone. We do not store the address or the answer.
The speed sample. Your phone downloads a few megabytes of meaningless data from us and sends about one megabyte of the same back, to time how fast data moves. Nothing of yours is in it, and we keep none of it.
Without an account, nothing is kept by us. Your last ten results stay on your phone.
With an account, your results are saved to it, so you can see them on any of your phones and so support can help you: the time, the verdict, your router's name, your provider's name and the measurements. Your public address is not saved. A test run behind your own smart.router is marked with that router, and the people who look after that router can see it.
Sharing. "Share" puts a result, with its numbers and addresses, into a message that goes only where you send it.

Your account

An account is an email address. If you sign in with Google or with Apple we also receive the name on that account. With Apple you can hide your email address; Apple then gives us an address that forwards to you. We keep your notification settings and, if you allow notifications, a token that lets us send alerts to that phone. That is all an account holds. You do not need an account to use the network test.

Deleting your account

You can delete your account in the app: open the menu, tap your email address, then Delete my account. That removes your sign-in, the phones registered for alerts, your notification settings and your saved network tests, at once. If you are the last owner of a router, the app tells you before you confirm what that means: your internet stays on, smart.router stops working on that router, and you would switch between your internet lines on your own.

Where your traffic goes

Nowhere near us. When a connection fails, the router itself moves traffic to another one, using a plan it already holds. Our servers are not in the path, and if they were unreachable for a week your failover would carry on working. The one exception is a speed test, which you start yourself, and which runs to a measurement server for a few seconds and then stops.

Who can see it

You, and anyone you have explicitly invited to see that router. You can withdraw an invitation at any time.
Your internet provider's staff, who operate the service and support you.
Nobody else. We do not sell it, rent it, share it with advertisers, or use it to build a profile of you. There is no advertising in this product and no data brokerage behind it.

The assistant

The app includes an assistant that answers questions about your own network. When you ask it something, the question and a summary of that one router's current state are sent to Anthropic's API to produce an answer. It is scoped to the router you are looking at, it can only read, and it is specifically barred from running anything that would load your router or capture traffic. Anything you tell it to remember about your network is kept in a database file belonging to that router alone.

How long we keep it

Second-by-second traffic samples are kept for about a day and then deleted. Speed test results, device inventory and the record of connection failures are kept while the router is enrolled, so you can look back at what happened. Delete a router from the service and its data goes with it. Network test results saved to an account are kept while the account exists, at most the latest two hundred. Like every web service, our servers keep a routine log of requests, including the address each came from; it is used for security and troubleshooting only, and is overwritten within weeks.

Email

We send transactional email only, and only about your own routers. See Notifications for exactly which messages exist and how to turn them off.

Security

Everything between a router and our service runs inside an encrypted tunnel that the router opens outward; nothing needs to be opened to the internet at your end. Each router has its own key material. Console access uses your organisation's single sign-on. We do not hold administrative credentials for customer routers, by design, so there is no store of them to lose.
