Privacy Policy
This text is a reference model and does not replace review by a lawyer. It also has to be revisited once this site has its own domain, hosting and audience country, because those determine which data protection regime applies. Validate it before processing real personal data in production.
Who processes your data
This site is operated by Lucas Silva, who acts as the controller of any personal data processed here. The operator is based in Brazil, so processing is subject to the Brazilian General Data Protection Law (Lei nº 13.709/2018 — LGPD). Visitors in the European Economic Area, the United Kingdom and certain US states may hold additional rights under their local law; requests under any of those regimes go to the address on the Contact page.
What this site collects today
| Data | When | How |
|---|---|---|
| Nothing through analytics | — | This site currently loads no analytics of any kind |
| Nothing through advertising | — | This site currently loads no ad network and sets no advertising cookies |
| Name, email and message | Only if you write to the address on the Contact page | Sent directly by you |
| Values typed into calculators (weight, height, age and so on) | While you use a calculator | Processed in your browser only — never sent to us and never stored |
We do not sell, rent or share personal data with third parties for marketing.
That the table above is this short is a property of the current stage of the site, not a promise about the future. If analytics or advertising are ever added, this page is updated in the same release that adds them, and consent is requested before any non-essential cookie is written for visitors in Brazil, the EEA and the UK.
Purpose and legal basis
- Contact: to answer your question or request. Legal basis: steps taken at the request of the data subject (LGPD art. 7, V; GDPR art. 6(1)(b) where applicable).
Cookies
This site sets no cookies of its own and loads no third-party script that sets cookies.
Your browser lets you block or delete cookies for any site at any time, through its privacy settings. Because this site does not depend on cookies, blocking them changes nothing about how it works.
Calculator inputs
Every calculator on this site runs entirely in your browser. The numbers you type are used to compute the result on your screen and are discarded when you leave the page. They are never transmitted to a server, never logged, and never associated with you.
Your rights
You can request access to, correction of, portability of, or deletion of your personal data, as well as information about any sharing, and you may withdraw consent where consent is the basis. Since the only personal data this site holds is what you send by email, in practice this means the content of your own messages. Write to the address on the Contact page; we respond within 5 business days.
Retention
Email messages are kept only as long as needed to handle the request and any follow-up, and are deleted on request.
Children
This site is not directed at children and does not knowingly collect data from them.
Changes
This policy is updated whenever the site changes what it processes. The date at the foot of this page reflects the current version.
