Mancini Tech Solutions
Privacy-first apps for people who value their data
Your information stays on your device, not our servers. We build tools for communities that care about ownership.
Local-First
Your data lives on your device. No accounts, no cloud sync, no tracking.
Built to Last
Simple, focused tools that do one thing well. No bloat, no feature creep.
Community-Driven
We build for specific communities, not mass markets. Quality over quantity.

Stack Tracker Gold
For precious metals collectors

About
Jon is an indie developer based in Connecticut. After years of working in technology for companies like Apple, Netflix, Disney, and Yale, he started Mancini Tech Solutions to build the tools he wanted to exist.
He believes the best software respects its users. That means your data belongs to you, not to advertisers or data brokers. Every app he builds follows this principle.
