Privacy policy

Summary

The Atlas of Languages is an informational site with no accounts, no forms and nothing for sale. We do not collect names, e-mails or anything you type. What exists is Google Analytics audience measurement and two preferences stored in your own browser.

1. Who is responsible

The site is maintained by Junior Ribeiro, an individual based in Brazil, and is subject to the Brazilian General Data Protection Law (LGPD, Law 13,709/2018).

2. What data is processed

• Browsing data (Google Analytics 4): pages visited, interface language, usage events (language clicked, audio played, search made, chart switched), device and browser type, approximate country/region derived from the IP address, and a random client identifier stored in a cookie. Google Analytics 4 does not store the full IP address.
• Local preferences (localStorage): the interface language and the chosen chart shape. They stay in your browser only and are never sent to the site.
• Server logs: the hosting provider (Hostinger) keeps technical access logs with IP address, date and URL for a limited period, for security and diagnostics.

No data is used for advertising, commercial profiling or sale to third parties.

3. Legal basis and purpose

Processing relies on the controller’s legitimate interest (LGPD art. 7, IX) in understanding how the site is used and improving it, and on security (art. 7, VII). You may object at any time — see section 6.

4. Cookies and third-party services

• Google Analytics 4 (Google LLC): cookies _ga and _ga_*, valid for up to 2 years. Data may be processed outside Brazil under Google’s contractual safeguards. See policies.google.com/privacy.
• cdnjs (Cloudflare): delivers the D3.js library; it receives a technical request containing your IP.
• Web Speech API: when no recorded audio exists, the site asks your browser to read the phrase. This happens locally on your device; the site receives nothing.

Audio files are served by the site itself, with no extra tracking.

5. Retention

Google Analytics data is kept for 14 months and then aggregated. Server logs follow the hosting provider’s policy. Local preferences last until you clear your browser data.

6. Your rights and how to exercise them

You may confirm that processing exists, request access, correction, anonymisation or deletion, and object to processing. To block measurement, use a blocking extension, private browsing, or the Google Analytics opt-out add-on. Requests about personal data can be sent to the controller through the channels listed on the About page.

7. Children

The content is suitable for all ages and there is no collection aimed at minors.

8. Changes

This policy may change when the site gains new features. The date at the top indicates the current version.
