1. Purpose of this Policy

This Policy supplements the Privacy Policy of Willer · Systems and is intended to clearly explain how cookies and similar technologies may be used on the website.

The use of these technologies must comply with applicable law, especially Brazil’s General Data Protection Law (LGPD), Law No. 13,709/2018, whenever personal data is processed.

2. What Are Cookies

Cookies are small files or records stored on the device used by the visitor or associated with the browser while navigating a website.

These resources may allow certain browsing-related information to be recognized from one request to another, helping the website function properly, preserve preferences, support security, analyze performance, or serve other legitimately implemented purposes.

Cookies, by themselves, do not give the website unrestricted access to files stored on the user’s device and should not be confused with executable programs installed on the device.

3. Similar Technologies

In addition to cookies, certain features may use technically similar resources, such as browser local storage, session identifiers, pixels, server logs, or other mechanisms required for digital services to operate.

When these technologies are used for purposes equivalent to those described in this Policy, they will be handled according to the same principles of necessity, transparency, security, and data protection applicable to cookies.

4. How Cookies May Be Used

When actually implemented, cookies may be used to:

• ensure the proper operation of the website;
• maintain sessions or preferences required for browsing;
• preserve security and abuse-prevention mechanisms;
• identify technical issues and support website maintenance;
• understand, in aggregate or statistical form, how the website is used;
• measure performance and identify opportunities for improvement;
• remember choices made by the visitor, when this functionality is available;
• enable integrations or third-party services embedded in the website, when applicable.

The existence of these possibilities does not mean that all of them are currently implemented. The categories actually used depend on the features available on the website at any given time.

5. Necessary Cookies

Necessary cookies are those used to enable essential website features or preserve conditions that are indispensable to security, stability, or the proper functioning of browsing.

Depending on the website architecture, this category may include session identifiers, abuse-protection mechanisms, strictly technical preferences, or resources needed to deliver a page or feature requested by the visitor.

When a cookie is strictly necessary to provide a requested resource or ensure the essential operation of the environment, disabling it may prevent or impair the corresponding functionality.

6. Performance and Measurement Cookies

Performance or measurement cookies may be used to understand how visitors interact with the website, identify the most visited pages, detect errors, and assess overall performance.

When used, these resources must be configured in a manner consistent with their intended purpose and applicable privacy requirements.

Willer · Systems does not state, through this Policy, that any specific analytics or measurement tool is installed. The description of this category applies only to the extent that a resource of this nature is actually implemented.

7. Functional Cookies

Functional cookies may be used to remember choices made by visitors and allow certain preferences to be maintained between visits.

This may include, for example, language, the presentation of certain elements, or other experience settings if these features are made available by the website.

8. Advertising, Personalization, and Tracking

This Policy does not state that Willer · Systems uses behavioral advertising, interest profiling, remarketing, or cross-website advertising tracking.

If features of this nature are implemented in the future, this Policy must be updated to identify their purposes, cookie categories, third parties involved, and applicable choice mechanisms.

Likewise, the mere existence of external links or buttons that direct visitors to other services does not, by itself, mean that advertising cookies are installed on the Willer · Systems website.

9. Cookies and Third-Party Resources

Certain pages may embed or depend on resources provided by third parties, such as hosting services, protection services, fonts, videos, maps, forms, measurement tools, external platforms, or other components.

Depending on the form of integration, these third parties may set their own cookies or process technical information related to access.

When there is direct interaction with third-party environments, processing may also be subject to those providers’ own terms and policies.

Willer · Systems will seek consistency between the resources used and the purposes described in this Policy, without stating that a specific provider is present unless it is actually integrated into the website.

10. Cookie Duration

Cookies may have different durations depending on their purpose and configuration.

Session Cookies

They remain active during a browsing session and are normally no longer used after the browser or corresponding session is closed.

Persistent Cookies

They may remain stored for a defined period, allowing information or a preference to be recognized on subsequent visits.

The actual retention period depends on the cookie or technology implemented and must be compatible with its intended purpose.

11. First-Party and Third-Party Cookies

First-Party Cookies

They are set directly by the accessed domain or by resources controlled within the website itself.

Third-Party Cookies

They may be set by external services embedded in or used by the website when technically necessary for the corresponding functionality.

Classification as first-party or third-party does not, by itself, determine a cookie’s purpose. A third-party cookie may, for example, be strictly technical, while another may be used for measurement or personalization.

12. Cookie-Related Data

Depending on the technology used, cookies and similar resources may be associated with technical information such as identifiers, Internet Protocol addresses, browser information, general device characteristics, date and time, pages accessed, preferences, and interaction records.

When this information identifies or can make a natural person identifiable, its processing must comply with the Privacy Policy of Willer · Systems and applicable law.

13. Managing Cookies

Visitors may use the controls provided by their browser to view, block, limit, or delete cookies.

Procedures vary depending on the browser, device, and software version used. These options are typically available in areas related to privacy, security, browsing data, or site settings.

Deleting cookies that are already stored does not necessarily prevent new cookies from being set on subsequent visits if the browser continues to allow their use.

14. Consequences of Blocking Cookies

Blocking or deleting cookies may affect certain website features, especially when the technology is needed to maintain a session, security, preferences, or other resources requested by the visitor.

The impact will depend on the cookie category and the functionality associated with it.

15. Consent and Preferences

Not every cookie necessarily requires consent. The form of processing will depend on the purpose, the nature of the resource, and the applicable legal basis.

When a particular cookie or technology requires a choice from the visitor, appropriate mechanisms may be made available to allow acceptance, refusal, or configuration before activation, as applicable.

If the website begins using optional cookie categories, the corresponding controls must be consistent with the practices actually implemented.

16. Security

Willer · Systems adopts measures intended to reduce risks associated with the misuse of technologies employed on its website.

Cookie configuration must observe principles of necessity, minimization, and security, including appropriate technical attributes when available and compatible with the purpose of the resource.

17. Relationship with the Privacy Policy

This Policy specifically addresses the use of cookies and similar technologies.

Broader information about personal data processing, purposes, sharing, retention, security, and data subject rights is available in the Privacy Policy.

18. Changes to this Policy

This Cookie Policy may be updated whenever necessary due to technological developments, changes to website features, the addition or removal of services, infrastructure changes, or the need for legal or regulatory compliance.

The current version will be the one published at this address.

When changes are considered significant, a prominent notice may be provided on the website or through another appropriate means.
