Hey Product Hunt! 👋
I'm Yuxuan, the maker of Signature Sketch.
The Problem: Last month, I needed a simple digital signature for a document. I tried 5 different websites—they all asked for my email, required a subscription, or uploaded my personal data to a server.
The Solution: I decided to build a privacy-first alternative.
Signature Sketch is simple:
🚫 No sign-up required
🔒 100% Local processing (your data never leaves your browser)
📱 Mobile-optimized (draw easily with your finger)
✨ Transparent PNG export
It's open-source and free forever. I'd love to hear your feedback!

It's great to see that there are people who solve small problems with the right approach: no data required, maximum privacy, and open source. The only downside is the advertising banners on the sides. I recommend you consider another type of revenue stream, such as paid premium services. Good luck with your project!
