Static HTML first
Every tool page includes crawlable definitions, examples, frequently asked questions, canonical links, JSON-LD, and internal links before any browser-only interaction is required.
Private by design
Calculators run in the browser. Timestamp values, cron expressions, meeting times, and date inputs are not uploaded to an application server.
