Show HN: Free privacy-focused PDF tracking with analytics

Hi HN! I built PDFTrackr because document tracking shouldn't cost $45/month.

Currently 100% FREE while I gather feedback:

- Track who views your PDFs (page-by-page analytics)

- See time spent on each page

- Password protection & link expiration

- 500MB uploads (vs 100MB on most competitors)

- GDPR compliant with proper privacy controls

- Virus scanning on every upload

Tech stack: Next.js, PostgreSQL, Docker, PM2 clustering, Cloudflare

I'm planning paid tiers ($4-$19/month) for more storage and features. You can join the waitlist if interested.

Try it: https://pdftrackr.com

Looking for feedback on:

1. What features are must-haves that I'm missing?

2. Is the analytics data useful enough?

3. Would you pay $4/month for this?

Thanks for checking it out!
