Lynfas Cookie Policy

Last updated: 23/07/2026

This Cookie Policy explains how Lynfas uses cookies and similar technologies when you access our website, application or platform.

It explains which technologies may be used, for what purposes, for how long, with whom data may be shared and how you can manage your preferences.

This Policy supplements the [Lynfas Privacy Policy]([insert link]).

1. Who we are

Lynfas is operated by [full legal name], registered with the CNPJ under no. [CNPJ], with its address at [full address].

For questions about cookies and privacy, please contact us:

2. What are cookies?

Cookies are small files or identifiers stored in a user's browser or device when they visit a website.

We also use similar technologies, such as:

  • pixels;
  • tags;
  • SDKs;
  • local storage;
  • session identifiers;
  • measurement and advertising technologies.

These technologies may enable the website to function, keep a user signed in, save preferences, measure performance or display advertising.

Depending on their configuration and purpose, cookies may involve the processing of personal data.

3. Types of cookies used

3.1 Strictly necessary cookies

These cookies are required for the basic operation of Lynfas.

They may be used to:

  • keep the user signed in;
  • protect sessions and forms;
  • prevent fraud;
  • maintain account security;
  • allow access to restricted areas;
  • process payments;
  • record consent preferences;
  • balance server load;
  • comply with legal and security obligations.

These cookies cannot be disabled through the consent system when they are genuinely essential to the operation of the service.

3.2 Preference cookies

These cookies remember choices made by the user, such as:

  • language;
  • light or dark mode;
  • region;
  • display preferences;
  • platform settings.

When they are not essential, they will be enabled only after consent is provided.

3.3 Analytics or performance cookies

These cookies help us understand how users use Lynfas.

They may be used to:

  • measure pages visited;
  • identify errors;
  • analyze browsing time;
  • evaluate performance;
  • improve features and usability;
  • produce aggregated statistics.

These cookies will not be enabled before consent is provided, unless there is a valid legal basis and a configuration that complies with the principles of the LGPD.

3.4 Marketing and advertising cookies

They may be used to:

  • measure campaigns;
  • limit repeated advertisements;
  • identify interactions with advertising;
  • create remarketing audiences;
  • display advertisements related to the user's interests.

Marketing and advertising cookies will only be enabled with specific consent.

Lynfas must not use browsing data for personalized advertising when the user has declined that purpose.

3.5 Payment and fraud-prevention cookies

During a purchase or subscription, payment institutions and fraud-prevention partners may use cookies or similar technologies to:

  • process payments;
  • authenticate transactions;
  • detect suspicious activities;
  • prevent fraudulent chargebacks;
  • protect the user and Lynfas.

These cookies must be listed in the cookie inventory when they are installed on the user's device.

4. Legal basis

The legal basis depends on the purpose of the cookie:

  • strictly necessary cookies: performance of a contract, compliance with a legal obligation, security or legitimate interest, as applicable;
  • non-essential preference cookies: consent, where applicable;
  • analytics cookies: consent, except where another legal basis is properly documented;
  • marketing and advertising cookies: consent;
  • payment and fraud-prevention cookies: performance of a contract, security, fraud prevention or another applicable legal basis.

The use of one category does not automatically authorize the others.

5. Consent

When accessing Lynfas, a cookie banner will be displayed with clear options to:

  • accept all cookies;
  • reject non-essential cookies;
  • configure preferences by category.

Non-essential cookies will remain disabled by default until the user provides a positive, freely given, informed and specific indication of consent.

Simply continuing to browse will not be considered consent.

Rejecting non-essential cookies will not prevent access to Lynfas' basic features. However, some optional features may not function properly.

The user may change or withdraw their consent free of charge at any time through the “Cookie Preferences” button available in the website footer or another easily accessible location.

Lynfas may record information about consent, such as the date, time, policy version and authorized categories, to demonstrate legal compliance.

6. Third-party cookies

Lynfas may use third-party services, provided that they are actually installed and necessary for a purpose disclosed to the user.

Examples:

  • Google Analytics: traffic and performance analysis;
  • Meta Pixel: campaign measurement and remarketing;
  • Stripe, PayPal or other gateways: payments and fraud prevention;
  • security and authentication services: protection of accounts and transactions.

These third parties may process information directly from the user's browser or device in accordance with their own privacy policies.

Third parties used by Lynfas must be identified in the cookie inventory, including:

  • provider name;
  • purpose;
  • category;
  • duration;
  • country or region of processing;
  • corresponding privacy policy.

If a tool is not installed on Lynfas, it must not be mentioned as though it were in use.

7. International transfers

Some technology, analytics, advertising, hosting or payment providers may process data outside Brazil.

When an international transfer occurs, Lynfas will adopt the measures required by the LGPD and provide additional details in the Privacy Policy.

The user should also review the privacy policies of the respective providers.

8. Storage period

Session cookies are normally deleted when the browser is closed or when the session ends.

Persistent cookies remain on the device until:

  • they reach their expiration date;
  • they are deleted by the user;
  • they are replaced;
  • consent is withdrawn;
  • they are no longer necessary.

The exact periods must be stated in the cookie inventory.

Consent records may be retained for the period necessary to demonstrate the validity of the authorization, comply with legal obligations and exercise rights.

9. How to control cookies

The user can control cookies in different ways:

  1. through the Lynfas preference banner;
  2. through the “Cookie Preferences” button;
  3. through browser settings;
  4. by blocking or deleting stored cookies;
  5. by using tools made available by third parties.

Deleting necessary cookies may end sessions, remove preferences or prevent certain areas from functioning.

Changing browser settings does not necessarily replace the withdrawal of consent recorded by Lynfas. We therefore also recommend using the platform's preference panel.

10. Data subject rights

Under the LGPD, the user may request, where applicable:

  • confirmation that processing exists;
  • access to data;
  • correction of incomplete or inaccurate data;
  • information about data sharing;
  • deletion of data processed with consent;
  • withdrawal of consent;
  • anonymization or blocking of unnecessary data;
  • portability, when regulated and technically applicable;
  • review of automated decisions, where applicable.

Requests must be sent to [email protected].

Some data may be retained when required by law, necessary for security, fraud prevention or the regular exercise of rights.

11. Security

Lynfas will adopt reasonable technical and administrative measures to protect data processed through cookies and similar technologies.

These measures may include:

  • use of a secure connection;
  • access controls;
  • encryption where applicable;
  • security monitoring;
  • restrictions on third parties;
  • fraud prevention;
  • periodic review of providers.

No system is completely secure. If a relevant incident occurs, Lynfas will take the measures required by applicable law.

12. Children and adolescents

Lynfas is intended exclusively for persons aged 18 or older.

We do not use cookies for the purpose of creating profiles of children or adolescents.

Lynfas may adopt age-verification mechanisms and technical measures to prevent minors from accessing restricted areas or content, in accordance with applicable law.

Additional information about age verification and data processing is available in the Privacy Policy.

13. Changes to this Policy

This Policy may be updated to reflect:

  • legal changes;
  • new technologies;
  • changes in providers;
  • changes in purposes;
  • operational changes;
  • recommendations from the ANPD.

The new version will be published on this page with its corresponding update date.

When a change significantly modifies the purpose or method of processing, Lynfas may request renewed consent.
