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 | Where | Purpose | Retention |
|---|---|---|---|
| Linear OAuth tokens (access + refresh) | Google Apps Script UserProperties (per-user, encrypted by Google) | Authenticate with Linear API | Until you disconnect or tokens expire |
| Linear OAuth tokens (cache) | Google Apps Script UserCache (per-user, encrypted by Google) | Reduce token refresh calls | Up to 6 hours (Google-managed TTL) |
| Linear Client ID / Secret | Google Apps Script ScriptProperties (app-wide, encrypted by Google) | Configure Linear OAuth | Indefinite (set by admin) |
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.
Third-Party Services
| Service | Purpose | Data Sent |
|---|---|---|
Linear API (api.linear.app) | Fetch entity metadata for preview cards | Linear OAuth access token + entity identifier |
| Google Apps Script | Runtime environment | All processing happens within Google's 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.
