This privacy notice explains how Calcular.online and SQL-Format.io handle visits, cookies, local storage, advertising, and contact submissions in plain language aligned with GDPR and LGPD principles. We minimize collection to what is needed to serve pages, measure aggregate traffic, and deliver optional ads that fund hosting costs.

When you browse, our server sees your IP address transiently to complete the HTTP request but stores only a SHA-256 hash of that address in visit logs, never the raw IP. A random session cookie, browser family, device type, page name, and timestamp are recorded to detect popular tools and abuse patterns; country hints come from Cloudflare CF-IPCountry when present.

Calculator inputs and results stay on your device via localStorage after successful runs unless you email us through the contact form, in which case we process your name and address solely to deliver that message. Third-party ad networks may set their own cookies subject to their policies—we do not share your calculation data with advertisers.
