How we handle your data

The short version

No analytics. No tracking cookies. No advertising. We do not sell, share, or profile your data. The only information that leaves your device is the text you submit for analysis, and that is sent straight to an AI provider under a zero-data-retention agreement - it is not stored or used to train models.

What we store

We store almost nothing. The only server-side state is an IP-keyed daily quota counter held in Cloudflare KV. It records how many API requests a given IP address has made in the current 24-hour window so we can enforce the free-tier rate limit. The counter expires automatically at midnight UTC and is never linked to any personal identifier beyond the IP address itself.

Published briefings (the question, the mapped positions, and the structural analysis) are editorial content authored for the site. They contain no personal data.

AI providers

When you submit text for analysis, it is forwarded to Google Gemini under Google's Zero Data Retention policy for the Gemini API. This means Google does not store your input or output, and the content is not used to improve Google's models. You can read Google's terms at cloud.google.com/terms/data-processing-terms.

We do not use the Anthropic API for public requests at this time. If that changes, this page will be updated.

Cookies

We set no tracking or analytics cookies. The site does not use any third-party scripts (no Google Analytics, no Meta Pixel, no ad networks). Your browser may cache static assets as normal HTTP caching - that is not a cookie.

The Chrome extension

The Whetstone extension audits the argument on a page you choose. When you run an audit, the selected passage or article text is sent to the same AI provider (Google Gemini, under the zero-retention policy above) and the result is shown in the side panel. The page content is not stored on our servers.

The extension reads a single cookie - your whetstone_session sign-in cookie - only to recognise whether you have an account, so it can show the right features. It does not read other cookies or track your browsing.

Optional usage analytics are off by default and can be enabled in the extension's settings; no page content is ever included. If you paste your own Gemini API key for deeper analysis, it is stored locally in your browser and never sent to us.

Your rights

Because we collect no personal data beyond ephemeral IP-based counters, there is nothing to request, correct, or delete. If you have a question or concern, email daniel.livingstone44@gmail.com.
