Privacy policy

Last updated November 8, 2026

Moonlight ("we", "us") is a family calendar that shows a household's Google Calendar and the weather on a display at home, such as a tablet in the kitchen, and lets the household add and change events from their phones. This policy explains what information Moonlight collects, how we use it, and the choices you have. It covers the Moonlight website and app at moonlight.itsandrew.com.

What we collect

• Your account. Your email address, and your name if you sign in with Google. If you sign in with an emailed link, we send that link to your email address.
• Your household. Its name, time zone, date format and units, and who belongs to it and in what role.
• Google Calendar, if you connect it. With your permission, we receive your Google account's email address and ID, the list of your calendars (names, colors and whether you can edit them), and the events on the calendars you choose to show: their titles, times, locations, descriptions, whether they repeat, and whether you declined them. We also keep a token from Google that lets Moonlight keep your calendar up to date without you signing in again.
• Events you add from your phone. Moonlight writes the event to your Google Calendar. Events created through Moonlight carry a private note, visible only to apps you've authorized, recording which household and person created them.
• Displays. Each display's name and settings, when it was last online, the IP address it paired from, and a regular health report: the app version, how long it has been running, its last error, its battery level, screen size and browser, and how far its clock is off. We use this only to keep displays running and to fix problems.
• Weather location. The place you choose for your household's weather. If you use your phone's location for this, it's rounded to about a kilometre before it's saved.
• Messages, if you install the app. The notes and announcements your household posts, who posted them and which displays dismissed them. Notes are deleted once they expire or you remove them, and announcements after a day.
• A record of changes. Important actions, like connecting a calendar or removing a display, are logged with who did them and when.

How we use it

Only to provide Moonlight to you and your household: to show your calendar and weather on your displays, to let you add and change events from your phone, to sign you in, to keep your displays working, and to keep the service secure. We don't sell your information, we don't show ads, and we don't use your information to build profiles about you.

Google user data

Moonlight asks Google for two calendar permissions:

• See, edit, create and delete events on your calendars (calendar.events), to show events on your displays and to let you add, change and delete events from your phone. Moonlight only changes an event when someone in your household does so in Moonlight.
• See the list of your calendars (calendar.calendarlist.readonly), so you can choose which ones show at home.

Specifically:

• We use Google Calendar data only to show it to the members and displays of the household you connected it to, and to make the changes you ask for.
• We don't transfer it to anyone else, except as needed to run the service (see "Who we share it with"), for security, or to comply with the law.
• We don't use it for advertising, and we don't sell it.
• We don't use it to develop, improve or train artificial intelligence or machine learning models.
• No person at Moonlight reads it unless you ask us to for support, it's needed for security or to investigate abuse, or the law requires it.

You can disconnect a Google account at any time on your phone in Moonlight (Calendars → Disconnect). We then delete its token and the events we stored from it, and ask Google to revoke Moonlight's access. You can also remove Moonlight's access from your Google account settings.

Who we share it with

We share information only with companies that help us run Moonlight, and only what they need to do that:

• Our hosting, database and network providers, which store and carry the data on our behalf.
• Our email provider, which sends sign-in links and account emails.
• Open-Meteo, which receives your weather location, and the text of any place search, but not who you are, to return the forecast and search results.
• The OpenSky Network, if you install Planes Overhead, which receives an area around your weather location, rounded to about 10 km, but not who you are, to return the planes in it.
• Google, when you connect your calendar or sign in with Google.

The website loads its fonts from Google Fonts, which receives your device's IP address when a page loads. We may also disclose information if the law requires it, or to protect the safety of our users or the service.

Cookies

Moonlight uses only the cookies it needs to work: one that keeps you signed in, one that identifies a paired display, and short-lived ones during sign-in and when you connect a calendar. We don't use advertising or analytics cookies.

How long we keep it

• Calendar events are kept only for the calendars you've chosen to show. Unchoosing a calendar or disconnecting an account deletes its events from Moonlight.
• Your account and household data are kept until you ask us to delete them. Removed displays stop working straight away.
• When we delete data, copies in our backups are gone within 30 days.

Security

All traffic to Moonlight is encrypted. Google tokens are encrypted before they're stored. Each household's data is kept separate from every other household's, both in the app and in the database. Access to our systems is limited to the people who run Moonlight.

Children

Moonlight accounts are for adults. Households often put their children's activities on their calendars, and those show on the household's displays and phones, but we don't knowingly collect personal information directly from children under 13. If you believe a child has given us personal information, contact us and we'll delete it.

Your choices

You can see and change your household's calendars, displays and settings in Moonlight on your phone. To get a copy of your data, correct it, or delete your account or household, email us at [set CONTACT_EMAIL] and we'll do it within 30 days. Depending on where you live, you may have other rights over your information; contact us to use them.

Changes to this policy

If we change this policy, we'll update the date at the top. If a change affects how we use your information in a significant way, we'll tell you by email or in the app first.
