About CalcWhale

CalcWhale is a collection of small, fast tools for everyday numbers and text: unit converters, calculators, and text utilities.

Three promises, kept on every page:

• Everything runs in your browser. Text you paste and numbers you enter are never uploaded, stored, or logged.
• Honest math. We show the formula and the working, flag estimates as estimates, and never inflate projections.
• No signups, no paywalls, no dark patterns. Every tool is free and loads in under a second.

For developers: the same team runs a small utility API — OG-image generation and PDF tools.
