Privacy

Last updated 16 August 2026

This extension has no server. There is no account, no analytics, no telemetry, and no usage tracking of any kind. Nothing is sent anywhere except the one API call described below, and that only happens when you press the button.

What leaves your browser

When you press Find events, the content you supplied — pasted text, and any PDF or image you attached — is sent directly from your browser to the Anthropic API (api.anthropic.com) so the event details can be extracted from it. The request also includes your current date and time zone, which is what lets phrases like "next Tuesday" resolve correctly.

That content is handled by Anthropic under Anthropic's privacy policy and the terms attached to your own API key. The extension's author never receives it, because there is no intermediary server to receive it.

Only submit content you're comfortable sending to a third-party API. A screenshot often contains more than the event you care about.

What stays on your device

These live in your browser profile's local extension storage. They are deliberately not put in Chrome's sync storage, which would copy them to Google's servers. They never leave the device, and uninstalling the extension deletes them.

The key is not encrypted at rest. Encrypting it locally would provide no real protection, since anything able to read the key could read the decryption key stored beside it. Treat it as readable by anyone with access to your computer, and set a spend limit on it.

Google Calendar

Events you approve are added by opening a Google Calendar page with the fields pre-filled, which you then save yourself. The extension requests no Google account access and holds no Google credentials.

The source code also supports writing events directly through the Google Calendar API, but that path requires an OAuth client the user configures themselves and is not enabled in the published extension.

Permissions

The published extension requests exactly two things: storage, to keep the settings above, and network access to api.anthropic.com. It cannot read your browsing history, your tabs, or the contents of any page. Its network access is additionally restricted by a content security policy so it cannot contact any other host.

Changes

If this notice changes in a way that affects what is sent or stored, the extension will ask you to acknowledge it again rather than changing quietly.
