Privacy Policy

最終更新日: 2026年4月23日

Overview

Smart Chips for Linear ("the Add-on") is a Google Workspace Add-on that previews Linear URLs as Smart Chips in Google Docs, Sheets, and Slides. This privacy policy explains how we handle your data.

Data We Access

Linear Data

  • When you paste a Linear URL, the Add-on fetches metadata (title, status, assignee, description, etc.) from the Linear GraphQL API (api.linear.app) to display a preview card.
  • The Add-on only reads data. It does not create, modify, or delete any data in Linear.

Google Account Data

  • Email address: Used solely to identify your account for Linear OAuth authentication.
  • Locale: Used to format dates in your preferred timezone.

Data Storage

Data We Do NOT Collect

  • We do not collect, store, or transmit any personal data to our own servers.
  • We do not use analytics, tracking, or advertising services.
  • We do not store Linear issue content, titles, descriptions, or any fetched metadata beyond the Google Docs preview card cache (managed by Google, ~5 minutes TTL).
  • We do not have our own backend servers. The Add-on runs entirely on Google Apps Script infrastructure.

Your Rights

  • Disconnect: You can revoke the Add-on's access to your Linear account at any time via Linear Settings > Authorized Applications.
  • Uninstall: You can uninstall the Add-on from Google Workspace at any time. Uninstalling removes all stored tokens.
  • Data deletion: Since we store no data on our own servers, uninstalling the Add-on effectively deletes all data.

Security

  • All communication with Linear API uses HTTPS (TLS 1.2+).
  • OAuth tokens are stored in Google's encrypted per-user storage (UserProperties), inaccessible to other users or the Add-on developer.
