Privacy Policy — Smart Claude Importer

Smart Claude Importer is a browser extension published by Antigravity Studio.
Last updated: October 9, 2026

Short version: your content stays yours. Web articles, text selections, and YouTube transcripts are processed locally on your device and uploaded directly into your own Anthropic Claude Projects when you explicitly ask for it. We collect no analytics, run no trackers, and never sell your data.

1. What data the extension handles

1.1 Content you choose to import

When you import an article, a highlight selection, or a YouTube video transcript, the content is extracted and converted into clean, structured Markdown locally inside your browser. When you confirm the import, that content is transmitted directly from your browser to Anthropic's Claude APIs (/api/organizations/{org_id}/projects/{project_id}/docs) using your active authenticated Claude session. Your content is stored solely within your chosen Claude Project Knowledge and is never routed through or stored on servers operated by us.

1.2 Pro license information (optional)

If you purchase and activate a Pro license, the extension sends your license key together with a randomly generated device ID (a pseudorandom identifier generated locally on your machine) over HTTPS to our license proxy — a Cloudflare Worker — which communicates with Creem.io, our payment provider and Merchant of Record, to activate and periodically re-validate (approximately once a week) your purchase. This request occurs only during initial key entry or automated periodic license status refreshes. License validation information is used solely to verify feature entitlements. Payments are completed entirely on Creem.io's secure checkout pages; the extension never sees or stores payment card numbers or billing details.

1.3 Settings and counters

Your configuration preferences (such as default Ingestion Format: Fast Link vs. Smart Reader, destination project preference, and batch selection states) and your daily import quota counter are stored locally in your browser's extension storage. The daily counter and cached license status are also mirrored into local origin storage to prevent accidental data loss. The extension collects no analytics, no telemetry, no browsing history, and no advertising identifiers.

2. How data is used

All data handling is strictly limited to providing the extension's single core purpose: converting and saving the web content you choose into your Claude Project Knowledge, and verifying optional Pro license purchases.

3. What is shared

We never sell user data and never transfer or share it for advertising, marketing, tracking, profiling, or any purpose outside the extension's stated features.

4. Security

All external communication occurs over encrypted HTTPS (TLS). Your Anthropic Claude authentication cookies and tokens are handled natively by your browser's cookie jar via standard credentialed requests and are never exported, logged, or exposed outside your local browser environment.

5. Retention and deletion

Local preferences, counters, and cached license information are deleted whenever you uninstall the extension or clear browser extension data. License records on Creem.io can be managed or deleted upon request via support. Documents imported into Claude reside in your Anthropic account and can be viewed, downloaded, or deleted inside Claude's Project Knowledge interface at any time.

6. Limited Use disclosure

The extension's use and transfer to any other app of information received from Google APIs / Chrome Web Store adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements:
