Archi-Civil is free to use, has no ads, and runs entirely in your browser — no account, no paywall, no tracking of your calculations. It is built and maintained independently, on personal time.
If a calculator saved you time, or you just want to help keep this project free and ad-free, a small contribution is genuinely appreciated — and directly funds the time spent verifying formulas, cross-checking against official standards, and adding new country code packs and languages.
Domain and hosting costs, and time spent on verification work — the part of this project that takes the longest and matters the most.
