Skylight is a private app one family uses on their own wall tablet. This page says what it does with the data their Google account lets it reach.

What Skylight asks Google for

• Read-only access to Gmail (gmail.readonly). Google's permission covers the whole mailbox, but Skylight only reads emails with the label the family chose (“Skylight” unless they change it), from the last month. It never sends, changes or deletes email.
• Access to Google Tasks (tasks). Skylight shows the family's lists, and adds, ticks off, renames and deletes items and lists when someone does that on the tablet or asks its voice assistant to.

Google Play services on the tablet gives Skylight short-lived access tokens. Skylight never sees or keeps the family's Google password, and keeps no refresh token.

What is sent to Anthropic

Skylight uses Anthropic's Claude, through Anthropic's API, to read the labelled emails. For each one it sends the email's text, up to three of its PDF or photo attachments, the family members' names as set up in Skylight and today's date, and gets back the events it finds.

When someone asks Skylight's voice assistant about a list (“what's on the shopping list?”), the items on that list go to Claude too, so it can answer.

Under Anthropic's commercial terms, data sent through its API isn't used to train Anthropic's models.

What is kept, and where

The events found in emails, a note of which emails were already read, and a copy of the family's lists are kept only on the tablet, in storage that is left out of Android's backups. When someone taps Add, the event goes onto the family's own Google Calendar, with a note of which email it came from. Disconnecting Gmail or Google Tasks in Skylight's settings deletes what was kept for it.

What Skylight doesn't do

• It doesn't sell, rent or share Google user data with anyone, apart from sending it to Anthropic as described above.
• It doesn't use Google user data for advertising, and it has no ads, analytics or tracking.
• No person reads the emails or lists except the family themselves.

Google API Services User Data Policy

Skylight's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Taking access away

Tap Disconnect in Skylight's Settings → Email or Settings → Lists, or remove Skylight under Third-party apps & services at myaccount.google.com/connections.

Changes

If Skylight starts using data differently, this page will change first, with a new date at the top.
