Privacy

Built to not collect your data.

On-page analysis stays on-device
All page audits run inside your browser. Zero data leaves your device — no domains, no page contents, nothing.
API key stored locally
Your key lives in Chrome storage and is only sent to api.rankparse.com when you explicitly request domain data.
No browsing history collected
RankParse never logs which pages you visit. Domain lookups are opt-in, per-click.

Install free. Start seeing data in under a minute.

No account, no card, no setup. Install the extension and click the icon on any page.
