Gmail AI Assistant adds a button inside Gmail's compose window that lets you rewrite your email draft using Claude, an AI model by Anthropic.
Your draft text is sent directly from your browser to Anthropic's API (api.anthropic.com) along with your chosen instruction (e.g. "make this more formal"), and the rewritten text is returned and placed back into your compose box.
We (the extension developer) do not operate a server, do not receive a copy of your email content, and do not log or store your drafts anywhere. The only parties who see your draft content are you and Anthropic, per Anthropic's own API data handling terms.
Your Anthropic API key is stored locally using Chrome's storage API
(synced across your own Chrome sessions if you're signed into Chrome). It is never
transmitted to us or any third party other than Anthropic.
No email content is ever stored by this extension. Each rewrite request is sent, processed, and discarded once the result is returned to your compose box.
| Data type | Collected? | Notes |
|---|---|---|
| Personally identifiable info | No | — |
| Authentication info | Yes | Your own Anthropic API key, stored locally only |
| Personal communications | Yes | Email draft text, sent to Anthropic to generate the rewrite you request — never stored by us |
| Website content | Yes | The active Gmail compose box content, only when you click the assist button |
| Location, web history, financial info | No | — |
We do not sell, share, or transmit any user data to third parties other than Anthropic, and only for the direct purpose of generating your requested rewrite.
If a future version introduces paid subscriptions, this policy will be updated before that version ships. At that point, we expect to additionally collect an email address (for account access) and subscription/billing status (processed by Stripe; we do not directly store payment card details). Draft content would, at that point, pass through our backend server to verify subscription status before each request, but would still not be stored or logged beyond the time needed to process each request.
You can remove your API key at any time from the extension popup, which stops all functionality. Uninstalling the extension deletes all locally stored data.
