Privacy policy

Last updated: 12 November 2026

This page explains what personal data is processed when you visit this website, book a lesson or contact Olaf, and what you can do about it.

1. Who is responsible

The data controller is Marcelo & Olaf, Lda. (NIF 519710193), Rua da Pedra do Cão, 440, 2K, 4400-396 Vila Nova de Gaia, Portugal. For any question about your data: olafaulaalemao@gmail.com or +351 965 797 608.

2. What data we process

• When you book a lesson in the online booking page: name, email, phone, the lesson you chose, the date and time, and any notes you write.
• When you contact us by WhatsApp, email or phone: your contact details and what you write to us.
• When you visit the website: only technical connection data, such as your IP address, which the servers receive to show you the page.

The level test and the pronunciation examples run only in your browser: your answers are not sent or stored.

3. What we use the data for

• booking, confirming, changing or cancelling lessons, and teaching them;
• replying to your messages and requests;
• issuing invoices and meeting legal obligations;
• keeping the website and the booking page secure.

The legal basis is, depending on the case, performing the service you asked for (or the steps before it), legal obligations, and our legitimate interest in keeping the website secure. We only send news or offers if you have agreed to it, and you can withdraw that at any time.

4. Who helps us process the data

• AgendaIG, the online booking page, run by IG Solution (NIF 239513576, Matosinhos, Portugal), which processes the data on our behalf.
• GitHub Pages, which hosts the website.
• Google Fonts, which provides the website's typefaces: when the page opens, your browser connects to Google's servers.
• WhatsApp (Meta), if you choose to contact us there. WhatsApp's own privacy policy also applies.

Some of these providers may process data outside the European Economic Area, using the transfer safeguards set out in the GDPR. We do not sell or share your data with third parties for advertising.

5. How long we keep it

We keep booking data while you are a student and for as long as needed to resolve any questions. Invoices and accounting records are kept for the period required by law (10 years in Portugal). Messages that did not lead to lessons are deleted when no longer needed.

6. Cookies

This website does not use cookies, analytics or advertising tools, and does not track you on other websites. The online booking page stores in your browser only what it strictly needs to work.

7. Your rights

You can ask to access, correct or delete your data, to restrict or object to its processing, and for data portability. Just write to olafaulaalemao@gmail.com. If you believe your data has not been handled properly, you can complain to the Portuguese data protection authority (CNPD).

8. Changes

This policy may be updated if the website or the way lessons are booked changes. The date at the top shows the current version. If there is any difference between languages, the Portuguese version prevails.
