About the startup
CalcLeaf is a free collection of 170+ browser-based tools — calculators (finance, health, math), text tools, PDF tools, and developer tools (JSON/JWT converters, formatters, generators, and more). Everything runs entirely client-side — nothing you enter or upload is ever sent to a server. No ads, no tracking, no sign-up required. Built and maintained solo, with a focus on speed and privacy over ad-heavy clutter. Would love feedback on what's missing!
