5. Cookie Categories Used on the BNF Website

The BNF Website’s current cookie-consent interface identifies the following categories:

1. Necessary Cookies;
2. Functional Cookies;
3. Analytical Cookies;
4. Advertisement Cookies; and
5. Unclassified Cookies.

The availability and specific configuration of these categories may change as the Website, its plugins, services, or third-party integrations change.

6. Necessary Cookies

Necessary cookies are used to support essential Website functionality. These cookies may be required for:

• Website security;
• Navigation;
• Basic functionality;
• Consent-management functions;
• Remembering privacy preferences;
• Technical operation of the Website; and
• Other essential services.

The BNF Website currently identifies necessary cookies as always active because certain essential Website functions depend on them. Where a cookie is strictly necessary for a service specifically requested by a visitor or for the basic operation of the Website, it may not be possible to disable it through the Website’s cookie-preference interface.

7. Functional Cookies

Functional cookies support additional Website features and user preferences. Depending on the Website configuration, these cookies may support:

• Interactive Website features;
• Content sharing;
• Feedback functions;
• Embedded services;
• Third-party tools;
• User preferences; and
• Enhanced Website functionality.

The current BNF cookie-consent interface describes functional cookies as supporting features such as content sharing, feedback collection, and third-party tools. If functional cookies are disabled, some Website features may not operate as intended.

8. Analytical Cookies

Analytical cookies help BNF understand how visitors interact with the Website. They may provide information such as:

• Number of visitors;
• Number of page views;
• Popular pages;
• Traffic sources;
• General visitor behavior;
• Time spent on pages;
• Navigation patterns;
• Bounce or engagement information;
• Device or browser information; and
• Website performance indicators.

The current BNF cookie interface describes analytical cookies as being used to understand visitor interactions, including metrics such as visitor numbers, bounce rate, and traffic sources. Analytical information helps BNF understand which Website content is useful and identify areas for improvement.

9. Advertisement Cookies

Where advertisement or advertising-related technologies are enabled, advertisement cookies may be used to:

• Deliver relevant advertising;
• Measure advertising effectiveness;
• Understand interactions with advertisements;
• Limit repetitive advertising;
• Support advertising campaigns; or
• Analyze interactions associated with advertising.

The current BNF cookie-consent interface identifies an Advertisement Cookies category and describes it as supporting personalized advertising based on previous visits and analysis of advertising campaign effectiveness. BNF may change, disable, or remove advertising-related technologies depending on its Website strategy and third-party services. BNF does not necessarily use advertising cookies simply because the category appears in the Website’s consent-management interface.

10. Unclassified Cookies

Unclassified cookies are cookies whose purpose or provider has not yet been fully classified. The BNF Website’s current consent interface describes these as cookies that are being classified together with the providers of the individual cookies. BNF may periodically review unclassified cookies and assign them to an appropriate category where sufficient information becomes available.

11. First-Party Cookies

First-party cookies are cookies placed directly by the BNF Website or its authorized Website systems. These cookies may support functions such as:

• Website operation;
• Security;
• Consent management;
• User preferences;
• Basic functionality; and
• Website analytics where applicable.

The precise cookies used may change as the Website is updated.

 12. Third-Party Cookies

Third-party cookies may be placed by external services integrated into the Website. Depending on the Website’s configuration, these services may include providers supporting:

• Website analytics;
• Social-media sharing;
• Embedded videos;
• Maps;
• Forms;
• Security;
• Website performance;
• Communication tools;
• Donation or payment functions; or
• Other third-party functionality.

Third-party providers may process information according to their own privacy policies and terms. BNF does not control every technical process carried out by third-party providers. Users should review the privacy policies of relevant third-party services when appropriate.

13. Cookie Consent Management

The BNF Website currently provides a cookie-consent interface that allows visitors to:

• Accept All cookies;
• Reject All optional cookies;
• Customize cookie settings;
• Save My Preferences; and
• Review available cookie categories.

Necessary cookies remain active because they support essential Website functions. Where applicable, visitors may change their preferences through the Website’s cookie-management interface.

14. Your Cookie Choices

Depending on the cookies being used, visitors may have the ability to choose whether to permit:

• Functional cookies;
• Analytical cookies;
• Advertisement cookies; and
• Other non-essential cookies.

If you reject optional cookies, certain Website features may not operate as expected. Your choice to reject optional cookies does not normally prevent you from accessing basic public Website content.

15. Changing Cookie Preferences

Visitors may change their cookie preferences using the cookie-consent controls provided on the Website. The Website may provide options such as:

Accept All

Allows applicable cookie categories according to the Website’s consent configuration.

Reject All

Rejects optional cookie categories while retaining necessary cookies.

Customize
Allows visitors to select individual cookie categories.

Save My Preferences

Stores the visitor’s selected preferences. The exact interface may change as the Website’s cookie-management system is updated.

16. Browser Cookie Controls

Most modern web browsers provide controls that allow users to:

• Block cookies;
• Delete cookies;
• Allow cookies;
• Block third-party cookies;
• Receive warnings before cookies are stored; or
• Manage website-specific cookie settings.

If you disable cookies through your browser, some Website functions may not work properly.

Because browser settings differ, users should consult the help documentation provided by their browser manufacturer for instructions.

17. Cookie Duration

Cookies may be classified according to how long they remain on a device.

Session Cookies

Session cookies generally remain on a device only while a browser session is active and may be removed when the browser is closed.

Persistent Cookies

Persistent cookies may remain on a device for a defined period after a browser session ends. The retention period varies depending on the purpose and provider of the cookie. BNF may review and modify cookie retention periods when Website services change.

18. Consent Preference Cookies

The Website may use a cookie or similar technology to remember a visitor’s cookie-consent preferences. This allows the Website to avoid repeatedly asking the visitor to make the same choice during every visit. If consent information is deleted or expires, the Website may ask the visitor to select cookie preferences again.

19. Analytics and Website Improvement

Where analytical cookies are enabled, aggregated or pseudonymous information may help BNF understand:

• Which pages receive attention;
• How visitors navigate the Website;
• Whether Website content is useful;
• Where visitors encounter difficulties;
• Which content requires improvement;
• General traffic patterns; and
• Overall Website performance.

BNF may use these insights to improve:

• Website navigation;
• Content;
• Accessibility;
• Performance;
• User experience;
• Communications; and
• Public access to conservation and research information.

20. Advertising and Campaign Measurement

If advertising cookies or related technologies are enabled, information may be used to assess the effectiveness of digital campaigns. Depending on the service provider, this may involve information such as:

• Whether an advertisement was displayed;
• Whether a user interacted with an advertisement;
• General campaign performance;
• Referring sources; and
• Aggregate engagement measurements.

BNF will seek to configure such technologies consistently with its applicable privacy and consent practices.

21. Social Media and Embedded Content

The Website may contain links, sharing tools, embedded media, or other functionality provided by social-media or third-party platforms. Such services may use cookies or similar technologies when their content is loaded or interacted with. Third-party platforms may collect information according to their own policies. Examples of such functionality may include:

• Social-media sharing;
• Embedded videos;
• Social-media feeds;
• External media players;
• Maps;
• Interactive content; or
• Other embedded services.

Where practical, BNF may configure third-party services to reduce unnecessary data collection, but the behavior of third-party systems remains subject to their own technical architecture and policies.

22. Embedded Video and Media

If the Website embeds video, audio, maps, documents, or other media hosted by third-party services, those providers may use cookies or similar technologies. The third party may collect information about:

• Browser;
• Device;
• IP address;
• Interaction with embedded content;
• Playback activity; or
• Other technical information,

depending on the provider’s configuration and policies.

Users should consult the relevant provider’s privacy policy for more information.

23. Security Cookies

Certain cookies or similar technologies may support Website security. They may help with:

• Detecting unusual activity;
• Protecting forms;
• Preventing abuse;
• Maintaining sessions;
• Supporting authentication where applicable; and
• Protecting Website infrastructure.

Disabling security-related cookies may interfere with Website functionality.

24. Cookies and Personal Information

Cookies do not necessarily contain a person’s name, email address, telephone number, or other directly identifying information. However, cookie identifiers and associated technical information may sometimes be linked with other information that could identify a visitor. Where cookie-related information constitutes personal information, BNF will handle it according to its applicable privacy practices and Privacy Policy.

25. IP Addresses and Technical Information

Depending on Website configuration and third-party services, technical information associated with a visit may include:

• IP address;
• Browser type;
• Operating system;
• Device type;
• Screen characteristics;
• Referring webpage;
• Pages visited;
• Date and time of access;
• Approximate geographic information;
• Website interactions; and
• Technical diagnostic information.

Such information may be used for security, analytics, performance, troubleshooting, and other legitimate Website purposes.

26. Cookie Data Sharing

Cookie-related information may be accessible to:

• Authorized BNF personnel;
• Website administrators;
• Hosting providers;
• Analytics providers;
• Security providers;
• Website technology providers;
• Consent-management providers;
• Embedded-content providers; and
• Other authorized service providers.

BNF seeks to use appropriate service providers and to manage information responsibly. Third-party providers may process information under their own contractual terms and privacy policies.

27. International Data Transfers

Some third-party Website providers may operate infrastructure or process information outside Bangladesh. Where applicable, cookie-related information may therefore be processed in other jurisdictions. The privacy and data-protection requirements applicable to such processing may differ from those in Bangladesh. BNF seeks to take reasonable measures appropriate to its Website operations and applicable requirements when using third-party services.

28. Cookies and Children

BNF’s Website is not intended to use cookies to knowingly collect unnecessary personal information from children. Where Website content is accessible to children, BNF seeks to maintain appropriate privacy and safeguarding practices. Parents, guardians, educators, and responsible adults should encourage children to use websites responsibly and avoid submitting unnecessary personal information online.

29. Cookies and Donations

If BNF provides online donation functionality through the Website or an external payment provider, cookies or similar technologies may be used by the relevant service to:

• Maintain a secure transaction;
• Remember transaction-related settings;
• Prevent fraud;
• Support payment functionality; or
• Measure transaction-related performance.

Payment providers may operate under separate privacy policies and terms. BNF does not intend this Cookie Policy to replace the privacy policies of third-party payment providers.

30. Cookies and Contact Forms

Cookies or similar technologies may support Website forms and communications by helping with:

• Security;
• Spam prevention;
• Form functionality;
• Session management;
• User preferences; or
• Technical performance.

Information submitted through a contact form may also be subject to the BNF Privacy Policy.

31. Cookies and Website Accessibility

Some Website functions may depend on cookies or similar technologies. Disabling certain cookies may affect:

• Interactive functions;
• Preference settings;
• Embedded content;
• Forms;
• Consent controls; or
• Other Website features.

BNF seeks to maintain reasonable accessibility while recognizing that third-party technologies may affect Website behavior.

32. Cookie Inventory and Classification

BNF may periodically review cookies used by the Website. The cookie inventory may change when:

• WordPress plugins are installed or removed;
• Themes are updated;
• Website functionality changes;
• Analytics services change;
• Third-party integrations are added or removed;
• Security services change; or
• Consent-management tools are updated.

Consequently, a cookie listed today may not necessarily remain on the Website indefinitely.

Similarly, a new cookie may appear when a new Website function is introduced.

33. Unclassified Cookies Review

BNF may review unclassified cookies and seek information from relevant providers to determine:

• Cookie name;
• Provider;
• Purpose;
• Category;
• Duration;
• Data collected; and
• Whether the cookie is necessary or optional.

Once sufficient information is available, BNF may update the cookie classification.

34. Third-Party Privacy Policies

Where cookies originate from third-party services, users should consult those providers’ privacy documentation for detailed information about:

• Data collection;
• Data processing;
• Retention;
• International transfers;
• User rights;
• Advertising;
• Analytics; and
• Opt-out mechanisms.

BNF cannot independently control changes made by third-party providers to their systems or policies.

35. Do Not Track Signals

Some browsers offer “Do Not Track” or similar privacy settings. Because there is no universal technical standard governing how every third-party service must respond to such signals, the Website may not respond to every browser-level Do Not Track setting in the same manner. Where BNF provides a dedicated cookie-consent mechanism, visitors should use that mechanism to manage available Website cookie categories.

36. Cookie Policy and Privacy Policy

This Cookie Policy explains the use of cookies and similar technologies. The BNF Privacy Policy provides broader information concerning the handling of personal information, including information submitted through forms, applications, communications, donations, research activities, or other Website interactions. The two policies should therefore be read together.

37. Cookie Policy and Terms of Use

This Cookie Policy forms part of BNF’s broader Website policy framework. The BNF Terms of Use establish general rules concerning access to and use of the Website. Visitors should read both documents to understand their responsibilities and BNF’s approach to Website operation.

38. Changes to This Cookie Policy

BNF may update this Cookie Policy periodically to reflect:

• Changes to the Website;
• New technologies;
• New third-party services;
• Changes to cookies;
• Changes to consent mechanisms;
• Changes in privacy practices;
• Changes in applicable requirements; or
• Improvements in transparency.

When material changes are made, BNF may update the Last Updated date at the top of this Policy. Visitors are encouraged to review this page periodically.

39. Managing Cookies After Policy Changes

If the Website introduces new cookie categories or technologies, visitors may be asked to provide or update their cookie preferences. Where applicable, the Website’s consent-management interface will provide available choices. Previously selected preferences may not automatically apply to newly introduced technologies.
