What this site is for
This site gives educational information about savings and their taxes in Portugal. It isn't investment advice or a personal recommendation, and it doesn't offer, sell or distribute any financial product.
The site receives no payment from the institutions or products mentioned. Results are estimates based on the assumptions explained in the Methodology; they don't guarantee any future return.
Your data and cookies
The site collects no personal data and asks for no sign-up. Your answers, your budget and chosen scenario stay only in your browser, for as long as the tab is open. They're never sent to a server.
Two exceptions: if you hide the explanations (the small round buttons next to headings), or pick light or dark mode with the switch at the top of the page, your browser remembers it for your next visit. If you don't choose, the site simply follows your phone's setting. These choices are kept in your browser's local storage ("localStorage"), not in a cookie, and they're never sent anywhere. To erase them, clear this site's data in your browser.
The site uses no cookies and no audience measurement tools.
Like any host, Vercel keeps technical logs (for example the IP address and the page requested) to run and secure the site, under its own privacy policy.
Sources and accuracy
Tax rules and example returns come from official or recognised sources, listed in the Methodology, in force or published in 2026. These rules can change. To report an error, write to the contact address above.
Intellectual property
The site's texts, calculations and graphics are protected. Product and index names mentioned (for example MSCI World, iShares) belong to their owners and are only mentioned as sources.
