Cookie Policy

Last updated: August 2026 · Version 1.1

This policy explains what cookies are, which ones we use on the Aranis website, and how you can control your preferences at any time.

1. What are cookies

Cookies are small text files stored in your browser when you visit a website. We also use equivalent technologies such as local storage (localStorage) and session storage (sessionStorage). They allow the site to function, remember your preferences and, when you allow it, help us understand how the site is used.

2. Cookie categories we use

Necessary (always on)

Essential for the site to function. They cannot be disabled.

  • NEXT_LOCALE — stores your chosen language (cookie, ~1 year)
  • aranis_cookie_consent — stores your cookie choice (localStorage)
  • ara-session — keeps your conversation with Ara continuous (sessionStorage, cleared when the tab closes)

Analytics (optional)

Help us understand site usage so we can improve it. Enabled only with your consent.

  • Google Analytics via Google Tag Manager — cookies _ga, _gid, _ga_* (Google LLC)

Marketing (optional)

Used to measure campaigns and personalize communications. Enabled only with your consent. There are currently no active marketing cookies; the category is available for future use.

3. Legal basis and consent

Necessary cookies are used on the basis of legitimate interest and service performance. Analytics and marketing cookies depend on your free, informed, and unambiguous consent, in accordance with the LGPD (Law No. 13.709/2018) and the GDPR (EU 2016/679). We record your choice, the date and time, IP address, approximate location, and browser to evidence consent.

4. How to manage your preferences

You can change or withdraw your consent at any time using the button below. You can also block or delete cookies in your browser settings — but this may affect how the site works.

5. Third-party cookies

When you allow analytics, Google Tag Manager and Google Analytics (Google LLC) may set cookies. Processing by these providers is governed by their own privacy policies.

6. Retention

Necessary cookies expire as indicated above. Consent records are kept for as long as needed to evidence legal compliance.

7. Changes to this policy

We may update this Cookie Policy. Material changes will be communicated and, where required, we will request renewed consent.
