Privacy Policy

We built DenaliKit with privacy at its core. Here's exactly what we collect, what we don't, and why.

📅 Effective date: March 1, 2026
🔒
The short version: DenaliKit processes all files locally in your browser. Your PDFs and images are never uploaded to our servers — we literally cannot see them. We collect only what's necessary to run your account and process payments. We don't sell your data. Ever.

1 Who We Are

DenaliKit ("DenaliKit", "we", "us", or "our") operates the website at denalikit.com and provides browser-based PDF and image tools. This Privacy Policy explains how we collect, use, disclose, and protect your personal information when you use our Service.

For questions about this policy, please contact us at hello@denalikit.com.

2 Your Files — What We Don't Collect

We never see your files. All PDF and image processing in the DenaliKit toolkit runs entirely in your browser using client-side JavaScript libraries (pdf-lib, PDF.js, and the HTML Canvas API). When you drop a file into the tool, it is read into your browser's memory and processed locally. No file data is transmitted to our servers at any point.

This means:
