Privacy Policy

Last updated: July 2025

CalculaMargem (calculamargem.com.br) is a free portal of tools for calculating profit margin, markup and pricing. This Privacy Policy describes what information we collect, how we use it, and what your rights are as a user.

By accessing and using this site, you agree to the terms described in this policy.

1. Data We Collect

CalculaMargem does not require registration and does not directly collect identifiable personal data, such as name, email address, or national ID.

However, like any website, we automatically collect some browsing data through third-party tools:

• IP address (anonymized by Google Analytics)
• Device and browser type
• Pages visited and time spent on the site
• Traffic source (organic search, social media, direct access)
• Approximate geographic region (not your exact address)

All calculators on the site run entirely in your browser: the values you enter (prices, costs, margins) are never sent to any server.

2. Use of Cookies

Cookies are small text files stored in your browser. We use cookies for the following purposes:

2.1 Analytics cookies (Google Analytics)

We use Google Analytics to understand how visitors interact with the site — which pages are visited most, for how long, and where traffic comes from. This data is aggregated and anonymous, used solely to improve the site's content and tools.

Google Analytics uses cookies such as _ga, _gid and _gat. To learn more about how Google processes this data, see Google's Privacy Policy.

2.2 Advertising cookies (Google AdSense)

This site displays ads managed by Google AdSense. Google and its partners may use cookies to serve ads based on your prior visits to this site and other sites on the internet (personalized advertising).

Advertising cookies allow Google to:

• Personalize the ads shown based on your interests
• Limit how often you see the same ad
• Measure the effectiveness of ad campaigns

You can opt out of personalized advertising through Google's Ads Settings or by visiting aboutads.info.

3. How We Use the Data

The browsing data we collect is used exclusively to:

• Analyze site performance and identify opportunities for improvement
• Understand which tools and content are most useful to visitors
• Display relevant advertising through Google AdSense
• Ensure the site's technical operation

We do not sell, rent, or share your personal data with third parties, except with the service providers mentioned in this policy (Google Analytics and Google AdSense), which have their own privacy policies.

4. Third-Party Services

CalculaMargem uses the following third-party services, each with its own privacy policy:

5. Your Rights and Data Protection

We aim to follow data protection best practices in line with the principles behind regulations such as the GDPR (European Union), the CCPA (California), and Brazil's LGPD (General Data Protection Law) — even where a specific regulation may not directly apply to your location. In general terms, this means you can expect the following in relation to any data associated with you:

• Access: knowing what data about you is being processed
• Correction: having incomplete, inaccurate, or outdated data corrected
• Deletion: requesting the removal of unnecessary or excessive data
• Objection: objecting to certain data processing activities
• Portability: receiving your data in a structured format

Since we do not directly collect identifiable personal data, most such requests should be directed to Google, which processes analytics and advertising data on our behalf. For data processed by Google, visit the Google Account dashboard.

If you have any questions about this policy, please get in touch using the email address available on our About page.

6. Links to External Sites

CalculaMargem may contain links to external sites (such as marketplaces, retailers, or regulatory bodies). We are not responsible for the privacy practices of those sites and recommend that you review the privacy policy of any site you visit.

7. Changes to This Policy

This Privacy Policy may be updated periodically to reflect changes in our practices or in applicable regulations. When we make significant changes, we will update the "last updated" date at the top of this page.

We recommend reviewing this page periodically to stay informed about how we protect your information.
