Privacy Policy

1. What we collect

Email address (waitlist)

If you submit your email to join the waitlist, we store it to notify you when features go live. We do not share, sell, or rent your email to any third party. Ever.

Prompt classification

To decide whether a prompt you're about to send to an AI is a "thinking" task or a "lookup" task, the Try First extension sends the prompt text (up to 600 characters) to a classification service. By default this is MindFirst's own classification backend, running on Cloudflare Workers, and the request includes a randomly generated installation ID, not your name, email, or any other identifier, so we can enforce a free daily usage limit per install. The prompt text is used only to return a classification and is not stored on MindFirst's servers.

If you've reached your free daily limit and have saved your own Anthropic API key in the extension's settings, further classifications that day are sent directly from your browser to Anthropic's API instead, using your own key. In that case your prompt text goes to Anthropic, not to MindFirst, governed by Anthropic's privacy policy.

The prompt text itself is never written to your device's storage, by MindFirst or by the extension, either. It exists only in memory for the moment it takes to classify it, then is discarded.

Extension data (local only)

Everything else the extension tracks, your thinking streaks, session history, activity log, any optional reflection notes you type in the "Your thinking…" popup, and your own saved Anthropic API key (if you add one), is stored locally in your browser using chrome.storage.local. This data never leaves your device and is never transmitted to MindFirst's servers or any third party. Your saved API key is only ever sent to Anthropic directly, when you personally trigger the fallback described above, never to MindFirst.

Quiz results

The AI Literacy Score quiz runs entirely in your browser. Your answers and score are not stored on our servers. Nothing is sent anywhere when you complete the test.

Roast tool

Any conversation text you paste into the "Roast My AI Usage" tool is processed entirely in your browser using JavaScript. The text is never uploaded, logged, or stored anywhere outside your device.

Usage log (manual)

The manual usage log page stores data in your browser's localStorage. This data stays on your device and is not synced or shared.

2. What we do not collect

• No tracking cookies or advertising pixels
• No browsing history or behaviour analytics
• No device fingerprinting
• No sale of data to third parties, ever
• No AI training on your data

3. Third-party services

MindFirst is hosted on Netlify. Netlify may collect standard server logs (IP addresses, request timestamps) as part of their infrastructure. See Netlify's privacy policy for details.

The Try First extension's default classification runs on Cloudflare Workers, operated by MindFirst. Cloudflare, as our infrastructure provider, may retain standard connection-level logs (such as IP address) as part of running that service. See Cloudflare's privacy policy for details.

If you add your own Anthropic API key and exceed the free daily limit, further classification requests are sent directly to Anthropic. See Anthropic's privacy policy for details.

No advertising networks, analytics platforms (Google Analytics, Mixpanel, etc.), or data brokers are used on this site or in the extension.

4. Data retention

Waitlist email addresses are retained until you request deletion or we shut down the waitlist. Extension and log data lives in your browser until you clear it manually. The randomly generated installation ID used for free-tier classification is stored in your browser the same way, and is retained on MindFirst's classification backend only as needed to enforce the daily limit; prompt text sent for classification is not retained by MindFirst.

5. Your rights

You can request deletion of your email from our waitlist at any time by emailing us. For extension and log data, you control it directly. Clear your browser storage at any time.

6. Children

MindFirst is not directed at children under 13. We do not knowingly collect data from anyone under 13.

7. Changes to this policy

If we make material changes, we'll update the date at the top of this page. Continued use of the site after changes means you accept the updated policy.
