About Us

Master Key Genie is software for locksmiths who want master key systems that are accurate without being exhausting—built and supported by Appfinity LLC.

Our mission

Master keying should feel like a craft you control—not a tangle of spreadsheets and second guesses. We built Master Key Genie so you can design systems with confidence at the bench, take them into the field on your phone, and keep every device aligned when you are back online.

What we believe

Friendly beats clever. Clear layouts, plain language, and visuals that show the cylinder—not just numbers in a grid.
Accuracy is non‑negotiable. Bittings, pinning, and access relationships have to be right. The product is built around that discipline.
Your data stays yours. Offline-first storage, encrypted sync, and row-level security are part of the product—not an afterthought.
