Privacy and notices

How this site handles your visit, and where the information we publish about other providers comes from.

Your visit to this site

This site uses cookies to store analytics data and user preferences. What we keep, and why:

Analytics. We use Google Analytics to count visits and understand which pages are most useful. It sets cookies in your browser (_ga and _ga_*) with a random identifier and information such as the pages visited, where the visit came from and the type of device. If you prefer not to have these cookies, block or delete them in your browser settings.
Preferences. We store the language you choose in the menu (English or Português) or in the address (?lang=pt or ?lang=en) in the lua_lang cookie, for 1 year; this cookie stores only the language and applies to the subdomains of lua.email (such as the checkout and the panel). Without that choice, the home page uses your browser language or the country you are visiting from, and stores nothing.
Where your contact came from. We keep the page or campaign you came from in your browser session (cleared when you close the tab), so we know what led to your message when you fill in the form.
Security. Cloudflare, which delivers the site and protects the form against bots, may set its own technical cookies.

You can delete or block cookies in your browser settings. The site keeps working, and the language goes back to being chosen automatically. Questions about privacy: get in touch.

Contact form

When you fill in the contact form, your name, email, phone, company, city, and message go to Lua's sales system, along with the page you sent it from, the calculator result if you choose to send it, and, if any, the campaign that brought you to the site. We use this data only to reply and talk with you about subscribing. To view, correct, or delete your data, contact us on WhatsApp or through the contact form.
