Privacy Policy
TechPrep.fyi ("we", "us", "our") is an educational platform for software engineers and AI practitioners. This policy explains what information we collect, how we use it, and your rights regarding that information.
1. Information We Collect
We collect only the minimum data needed to operate the site.
We use Vercel Web Analytics to understand how visitors use TechPrep.fyi. This collects:
- Page views and navigation paths
- Country (derived from IP address, not stored)
- Device type, browser, and operating system
- Referrer URL (where you came from)
Vercel Analytics is privacy-friendly by design — it does not use cookies, does not fingerprint your device, and does not track you across websites. IP addresses are never stored. See Vercel's privacy documentation for full details.
Some pages include an AI Tutor powered by Anthropic Claude. When you use the chat:
- Your messages are sent to Anthropic's API to generate a response
- TechPrep.fyi does not store, log, or retain your chat messages
- Anthropic may retain messages per their own privacy policy
Do not share sensitive personal information in the AI chat.
We store your preferences in your browser's local storage (not cookies). This includes:
- Sidebar open/closed state
- Learning path topic completion progress
- Last selected navigation tab
This data never leaves your device and is not sent to our servers. You can clear it at any time by clearing your browser's site data.
2. Information We Do Not Collect
- We have no user accounts — we do not collect names, emails, or passwords
- We do not use advertising or third-party tracking pixels
- We do not sell or share any data with third parties for marketing purposes
- We do not use cookies for tracking or targeting
3. Third-Party Services
TechPrep.fyi uses the following third-party services, each with their own privacy policies:
- Vercel — hosting and analytics (vercel.com/legal/privacy-policy)
- Anthropic — AI chat responses (anthropic.com/privacy)
- Cloudflare CDN — delivery of highlight.js assets (cloudflare.com/privacypolicy)
4. Children's Privacy
TechPrep.fyi is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.
5. Data Retention & Deletion
Since we do not collect personal data, there is nothing to delete on our end. Analytics data collected by Vercel is aggregated and anonymous — it cannot be linked to an individual.
To clear your local preferences (progress, sidebar state), clear your browser's site data for techprep.fyi.
6. Your Rights
Depending on your location, you may have rights under GDPR (EU), CCPA (California), or other privacy laws. Since we collect no personally identifiable information, most of these rights are satisfied by default. If you have any questions, reach out via our support form.
7. Changes to This Policy
We may update this policy as the site evolves. The "Last updated" date at the top of this page will reflect any changes. Continued use of TechPrep.fyi after a change constitutes acceptance of the updated policy.
