Privacy policy

Last updated: 3 November 2026.

This English version is a translation provided for convenience. In case of doubt, the Portuguese version prevails: Política de privacidade.

1. Data controller

Francisco T. — contact for privacy matters: simplesirs.pt@gmail.com. We process data in accordance with the General Data Protection Regulation (GDPR; in Portuguese, RGPD).

2. The calculators collect no data

The figures you enter in the calculators (income, age, expenses) are calculated only on your computer or phone (in the browser) and are neither sent to us nor stored by us.

3. We do not ask for personal data

To use Simples IRS you do not need to create an account or give us your email or any other personal data. The site has no form that sends us data.

If you left us your email in the past, it remains securely stored and these rules apply:

  • What we keep: the email, the date you left it, the text of the consent you accepted at the time and the page where you did so. We did not keep IP addresses.
  • Use: we do not use it to sell anything and we never give or sell it to other companies.
  • Legal basis: the consent you gave at the time (Article 6(1)(a) GDPR). You can withdraw it at any time.
  • Deleting your email: just write to simplesirs.pt@gmail.com and ask. We delete the email and the associated data. In any case, it is deleted no later than 24 months after the date you left it.

4. Processors (companies that process data on our behalf)

The site is hosted by Cloudflare, Inc. (Cloudflare Pages). The emails left with us in the past are stored in a database, also at Cloudflare. Cloudflare acts as a processor under its data processing agreement, and there may be transfers outside the European Economic Area (EEA) based on the Standard Contractual Clauses and the EU-U.S. Data Privacy Framework. We do not sell or give emails to other companies.

5. Ads, cookies and statistics

To stay free, the site shows ads from Google AdSense, a service of Google Ireland Limited.

  • Third-party cookies: third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and to other websites.
  • Google advertising cookies: Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet. Google and its partners may also use cookies and other identifiers to measure how many people see the ads and to prevent fraud. They do so as data controllers, in accordance with Google’s privacy rules.
  • Consent, where the law requires it: visitors from the European Economic Area (EEA), the United Kingdom or Switzerland will be asked for consent through a Google-certified consent management platform before any personalised ad is shown. Without that consent, ads are not chosen based on your interests.
  • Changing your mind: press Manage cookies, at the bottom of any page. If the consent platform is available to you, the link opens it and you can change your choice; if not, it brings you to this section, where you will find the other ways to turn off personalised ads.
  • Turning off Google personalised ads: in Google Ads Settings (or at myadcenter.google.com).
  • Turning off other vendors’ cookies: at www.youronlinechoices.eu or at www.aboutads.info.
  • Learn more: How Google uses information from sites or apps that use its services and how Google uses cookies in advertising.

The figures you type into the calculators are never sent to Google or to advertisers.

To count visits, we use Cloudflare Web Analytics, which does not use cookies or build individual profiles.

6. Your rights

You can request access, rectification, erasure, restriction or portability, or object to processing, and withdraw your consent, by writing to simplesirs.pt@gmail.com. We will reply within one month. You also have the right to lodge a complaint with the Portuguese data protection authority, the Comissão Nacional de Proteção de Dados (www.cnpd.pt).

7. Security

Encrypted connections (HTTPS), database access restricted to the data controller and minimal data collection.
