Smart Calendar — Privacy Policy

Last updated: September 2026 (v1.0.5)

Smart Calendar is a Chrome extension that helps you create Google Calendar events and Google Tasks from text on any webpage. This policy explains what data is accessed and how it is used.

Data we access

• Selected text — when you right-click and choose "Create Calendar event", the text you selected on the page is read and used to parse event details (title, date, time). This text is processed locally in your browser and is never sent to any external server by this extension.
• Google account (OAuth) — the extension requests a Google OAuth token via Chrome's built-in identity API (chrome.identity). This token is used solely to create events in your Google Calendar or tasks in Google Tasks on your behalf. The token is never stored or transmitted to any server other than Google's APIs.
• Google Calendar — when creating a calendar event, event data you enter (title, date, time, location, notes) is sent directly to the Google Calendar API (https://www.googleapis.com/calendar/v3/) to create your event. No copy of this data is retained by the extension.
• Google Tasks — when creating a task, task data you enter (title, due date, notes) is sent directly to the Google Tasks API (https://tasks.googleapis.com/tasks/v1/) to create your task. No copy of this data is retained by the extension.

Data we do NOT collect

• We do not collect, store, or transmit any personal data to our own servers.
• We do not track browsing history or page content beyond the text you explicitly select.
• We do not share any data with third parties (other than Google's Calendar and Tasks APIs, as described above).
• We do not use analytics or crash-reporting services.

Permissions used

• identity — to sign you in with Google and obtain Calendar and Tasks API access tokens.
• contextMenus — to add the "Create Calendar event" option to the right-click menu.
• storage — used to store your optional Claude API key and workspace ID locally in your browser. This data never leaves your device.
• host permissions (googleapis.com, tasks.googleapis.com) — to call the Google Calendar and Tasks APIs to create your events and tasks.
• host permissions (api.anthropic.com) — only contacted if you choose to enter a Claude API key (see below). Used solely to generate smarter event titles from selected text.

Third-party services

This extension communicates with the following external APIs:

• Google Calendar API — for creating calendar events. Governed by Google's Privacy Policy.
• Google Tasks API — for creating tasks. Governed by Google's Privacy Policy.
• Anthropic Claude API — optional. Only used if you enter your own Claude API key in the extension settings. When active, the text you select on a page is sent to Anthropic's API to generate a smarter event title. No data is stored by Anthropic beyond its standard API usage logs. You can remove your API key at any time via the extension settings; the extension works fully without it.

Changes to this policy

If this policy changes materially, the updated version will be posted at this URL with a new "Last updated" date.
