Privacy policy

Short version: we do not ask for your details, analytics only runs if you accept it, and the growth calculator never sends what you type anywhere.

Who we are

Baby Growth Club is operated by PG App Studios, Algarve, Portugal. Contact: pgmetastudios@gmail.com.

The growth calculator

All calculations run in your browser. Nothing you enter is stored or transmitted.

Cookies and analytics

We use Google Analytics 4 to understand which pages are useful, only if you tap Accept on the cookie banner. Until then no analytics code or cookie is loaded. If you accept, Google Analytics sets cookies named _ga and _ga_* (kept up to 2 years) and processes pseudonymous usage data such as pages viewed, device type and approximate country, with IP addresses anonymised. Google may process this data outside the EU under the EU-US Data Privacy Framework and standard contractual clauses.

Your choice is saved in your browser (localStorage key bgc:consent). You can change it at any time with Cookie settings in the footer. Declining removes the analytics cookies.

Legal basis: your consent (GDPR art. 6(1)(a)). We do not use advertising cookies.

Hosting logs

Our hosting provider may keep standard server logs (IP address, browser, time of request) for security, for a limited time.

Amazon links

When you click a link to Amazon, Amazon may set cookies under its own privacy policy to attribute the purchase.

Your rights

Under the GDPR you can ask us about any personal data we hold, and complain to the Portuguese data protection authority (CNPD).
