Legal Notice and Privacy

Calculadora Laboratorial Terms of Use, Privacy Policy and Cookie Policy.

Last updated: October 25, 2026.

In short: Calculadora Laboratorial is free. An account is optional unless the website starts requiring one. To create an account, you provide your name, email address, phone number and city, and create a password. We use this information to maintain your account, store your calculation history and favorites, and send you account notices and Calculadora Laboratorial newsletters. We do not sell your data. You can correct your information, unsubscribe from newsletters or delete your account at any time in My account. The calculators are support tools and do not replace clinical judgment.

1. Terms of Use

1.1 Who provides the service

Calculadora Laboratorial is a free laboratory and medical calculator platform (calculadoralaboratorial.com.br; contact details in Section 4), hereinafter "Calculadora Laboratorial," "we," "us" or "our."

1.2 Acceptance of these terms

Depending on the settings in force at any given time, the calculators may be used freely or may require a free account. An account also lets you save your history and favorites. Registration is completed only if you check the box accepting these Terms of Use, the Privacy Policy and the Cookie Policy, which includes agreeing to receive emails from Calculadora Laboratorial as described in Section 1.8. If you do not agree, do not complete registration. Reading the public pages of the website does not require registration.

1.3 Who Calculadora Laboratorial is for

Calculadora Laboratorial is free and may be used by healthcare and laboratory professionals, students, academics, teachers and anyone else interested, for educational or laboratory purposes, provided they are 18 or older. The calculators are for educational and informational purposes. Results do not constitute a diagnosis, prescription or laboratory report and do not replace assessment by a licensed healthcare professional. Every result must be interpreted within the patient's full clinical context and checked against the current literature and guidelines in your field.

1.4 Your account and password

You must provide accurate information and keep it up to date in My account.
Your account is personal and non-transferable. You are responsible for your password: do not share it. If you suspect unauthorized use, change your password in My account; changing it ends all other open sessions.
If you forget your password, use "Forgot your password?" on the sign-in page: we will send a code to your registered email address.

1.5 Patient data

Calculadora Laboratorial does not request or need any data that identifies patients. Do not enter names, ID numbers, medical record numbers or any other information that could identify a patient. Calculator fields should receive only numerical values and clinical options (for example, age, sex, weight and test results). The values you enter are saved in your history so that you can review them and repeat the calculation.

1.6 Permitted and prohibited use

You may use Calculadora Laboratorial for professional, academic and personal purposes. You may not:

copy, reproduce, distribute or commercialize the calculators, implemented formulas, texts, design or code of Calculadora Laboratorial without prior written authorization;
reverse engineer, extract data by automated means (unauthorized bots, scrapers or crawlers) or attempt to circumvent access or security mechanisms;
create fake accounts or accounts on behalf of third parties, share access to your account or use it to send spam;
overload, attack or interfere with the operation of the website.

1.7 Suspension and termination

We may suspend or block accounts that violate these terms, that show signs of fraud or automated use, or when required by law. A blocked account loses access immediately and cannot be recreated with the same email address. You may close your account whenever you wish in My account, using the "Delete my account and data" option.

1.8 Email communications

By creating an account, you agree to receive two types of emails from Calculadora Laboratorial:

Account and service notices: codes to create or reset your password, and notices about security and changes to these terms. These are always sent, as they are part of the service.
Newsletters and promotional content from Calculadora Laboratorial itself: news, new calculators, content and offers from Calculadora Laboratorial. Calculadora Laboratorial does not send third-party offers and does not share your email address with partners. You can stop receiving newsletters at any time in My account, under My details, or through the unsubscribe link in the emails themselves.

1.9 Accuracy of formulas and limitation of liability

The formulas are based on the scientific literature and on recommendations from health organizations, and they are reviewed periodically. Even so, science evolves and errors may exist. Calculadora Laboratorial is not liable for clinical decisions made solely on the basis of the results, for typing or unit errors in the values entered, or for misinterpretation of the results. If you find a possible error in a calculator, please let us know using the contact details in Section 4.

1.10 Intellectual property

The Calculadora Laboratorial brand, design, texts, source code and the way the calculators have been organized and implemented belong to Calculadora Laboratorial and are protected by Brazilian copyright law (Law No. 9,610/1998), software law (Law No. 9,609/1998) and industrial property law (Law No. 9,279/1996). Use of the platform does not transfer any of these rights to you.

1.11 Changes to these terms

We may update these terms. The date of the last update appears at the top of this page. Material changes will be announced by email and on the website with reasonable advance notice. If you continue to use Calculadora Laboratorial after the changes take effect, they will apply to you; if you do not agree, you may delete your account.

1.12 Governing law

These terms are governed by the laws of Brazil.
