COOKIES AND STORAGE
Cookies and preferences.
Keeping it simple.
How preferences, calculators and the private support session work.
Last reviewed: 5 October 2026
Cookies in this version
This version does not use analytics, advertising or visitor-tracking cookies. The calculators and presentation preferences work in page memory.
Support has a private session, separate from the calculators, so you can resume a conversation. The client sends session credentials to the support service. This session is necessary for private access and is not used for advertising. Read the support terms to understand the duration and use of the conversation.
Preferences and calculator
Calculator figures, reduced-motion settings and presentation selectors stay in page memory. The website does not save them in cookies, localStorage or sessionStorage. The page also respects your system's reduced-motion preference. This description of calculators does not apply to information you send in the support form: that conversation is received and stored by the support service.
Your browser may cache copies of files it downloads. That cache is not a record of figures entered in the calculator.
Server requests
The website is hosted on Cloudflare Pages. Hosting receives the requests needed to deliver pages, fonts and images. Support uses api.ravnu.com separately. The responsible party must confirm the purposes, retention periods for technical logs and other applicable details in the final policy.
If this version changes
If analytics, advertising, embedded content or persistent storage services are added, this page must be updated and information and consent requirements reassessed before activation.
Read the preliminary privacy policy to understand its scope and the details still to be confirmed.
Language cookie
We save your choice of English or Portuguese in a functional cookie for 12 months. It contains no identifier and is not used in statistics.
Launch list and verification.
The launch form contacts the list service when you check availability or submit a request. Turnstile anti-abuse verification loads only on the registration page. Your name, email and platform are not saved in cookies or the website's local storage. There are no marketing pixels or analytics cookies. Daily page-opening totals are aggregated without identifying visitors; browser privacy signals are respected.
The list keeps aggregate registration and removal counts. Sharing calculators does not send your figures; copying, downloading or printing is your action and may include those figures. Read the list information for retention periods and removal.
Website statistics.
We count page openings, registrations and removals by day and identified source for 90 days. Statistics do not include names, emails, financial figures, full referring URLs or persistent identifiers. Repeated openings count again and do not represent unique people.
We do not use cookies or browser storage for these counts. We respect Do Not Track and Global Privacy Control signals; pages with private resume or removal links are not counted. A temporary network limit uses a hashed key with a server secret, which stops being used after one hour; expired records are deleted during daily cleanup. Network requests pass through Cloudflare hosting, which may process technical information as described in this policy.
