What we collect, and what we don't

This website

Email sign-up

If you leave your email address, we use it to send a confirmation email (plus one reminder a day later if you haven't confirmed), then one email when the first batch is ready. We don't add you to anything else.

Buttondown, an email service in Richmond, Virginia, keeps the list and sends these emails for us. Along with your address, it records when you signed up, whether you confirmed, your IP address, the website you signed up from and, if one of our ads brought you, which ad. Our emails don't track whether you open them or click their links.

Every email has an unsubscribe link, and once you unsubscribe you won't hear from us again. Ask us and we'll delete your details entirely.

Visitor count

We count visits with Cloudflare Web Analytics so we know how many visitors sign up. It uses no cookies, doesn't store anything in your browser and doesn't fingerprint you. It records which page was viewed, the site that linked you here, your browser and device type, and your country. None of that is tied to you.

Hosting and fonts

Cloudflare hosts this site. Like any web host, it handles your IP address to deliver the page and block attacks. We don't receive or keep a log of who visited.

The page's fonts load from Google Fonts, so Google sees your IP address and browser when the page loads, as with any web request.

The monitor and the apps

Readings and history

The monitor measures CO₂, temperature and humidity, and keeps a short history. Your iPhone, Mac and browser read it directly over your home Wi-Fi. There's no account, and none of it is sent to us.

Anyone on your home Wi-Fi can open the monitor's page and see its readings. Only the app you set it up with can change its settings. CO₂ levels can hint when someone is home, so keep your Wi-Fi to people you trust.

Setup

During setup, your Wi-Fi name and password go from your phone straight to the monitor and are stored only on the monitor.

Software updates

The monitor goes online to check for and download its own software updates. Like any download, our update server sees your home's IP address, plus the monitor's model and software version. We use these only to deliver the update.

iPhone alerts (optional)

iPhone alerts are off until you turn them on. When they're on, the monitor sends each alert to our relay, which hands it to Apple's push service, which delivers it to your iPhone. This is the only reliable way for a home device to alert an iPhone.

Passing through the relay: the alert itself (the room's name, the CO₂ number and about how long to air), your iPhone's push address (a code Apple issues for our app), the time and your home's IP address. The relay keeps none of it once the alert is sent. Even so, when alerts happen can hint when someone is in a room, which is why they're off by default. Apple delivers the alert under its own privacy policy.

The relay can also nudge your widgets to refresh. The widget then reads the monitor directly over your Wi-Fi, so readings don't pass through the relay. You can turn iPhone alerts off at any time in the app's Settings.

Mac alerts

Alerts on your Mac are made by the Mac app itself. Nothing leaves your Mac.

Outdoor air check (optional)

If you turn on the outdoor air check, your phone asks Open-Meteo, a public weather service, for the outdoor air quality near you. The app asks for location only while you're using it, and rounds your place to about 1 km before saving it on your phone. Your widgets use that saved place, so they never ask for your location. Open-Meteo sees the rounded place and your phone's IP address. We never see either. Turning the check off deletes the saved place.

Crash reports

If you've chosen to share analytics with app developers in your iPhone or Mac settings, Apple may send us crash reports and usage statistics. They don't identify you.

Home Assistant

Home Assistant reads the monitor directly on your home network, the same way the apps do.

What we don't do

• We don't sell or share personal information, for money or anything else.
• We don't show ads or track you across other sites and apps.
• We don't buy data about you from anyone.

We don't sell anything yet. Before we do, this page will say what the store collects to take your order.

Your choices

You can unsubscribe from any email. You can also ask us to show you, correct or delete your details, and we'll answer within 30 days. Wherever you live, you get the same answer.

If you're in the European Union or the UK, we keep your email address because you agreed to it. You can withdraw that at any time, and you can complain to your local data protection authority. If you're in California, you have the right to know, correct and delete your personal information, and we won't treat you differently for asking.

Children

The sign-up isn't meant for children under 13, and we don't knowingly collect their information. If you think a child has signed up, tell us and we'll delete it.

Changes

If we change this policy, we'll update the date at the top. If a change affects how we use your email address, we'll email you before it applies.
