Privacy

Short version

InterviewPrep does not have user accounts, does not collect personal data, and does not set tracking cookies. Your study progress is stored entirely in your own browser via localStorage. The only analytics we run is Vercel Web Analytics, which is privacy-friendly (no cookies, no cross-site tracking, IP addresses are not retained).

What we store

The following keys are written to your browser’s localStorage as you use the site:

• reviewed:<conceptId> — boolean flag per concept you mark as reviewed.
• recall:state:<cardId> — SRS scheduling state per flashcard (ease factor, interval, due date).
• recall:stats — aggregate study stats (streak, total reviews, last study date).
• prepfast:last-topic— the slug of the last topic you opened (used to render the “Continue X” card on the home page).

None of this data leaves your browser. We never see it. To wipe it, clear your browser’s site data for InterviewPrep.

Analytics

We use Vercel Web Analytics to count page views and anonymous visit metrics. Vercel does not use cookies, does not track users across sites, and does not retain raw IP addresses. The data we see is aggregated: which pages are popular, which countries visitors are in, etc. We do not connect this to any individual user.

Third-party links

Pages may link to GitHub, Anthropic docs, MCP specifications, or other external sites. We’re not responsible for their privacy practices.

Cookies

We do not set any cookies. We do not embed third-party widgets that set cookies. The site works entirely on static HTML/JS/CSS plus your local browser storage.

Changes to this page

If we add a feature that changes data handling (e.g. an opt-in account system), we’ll update this page and the “Last updated” date at the top.
