What Are Cookies

Cookies are small text files that websites place on your device when you visit them. They allow the website to recognize your device and store certain information about your preferences or past actions. We use them for site security, performance analysis, and measuring marketing reach.

Types of Cookies We Use

The Website may use the following categories of cookies.

  • Required cookies: These are essential for the Website to function and cannot be disabled. We host the Website on Webflow, which utilizes Cloudflare to manage security, mitigate malicious traffic, and protect the Website from abuse.

  • Analytics cookies: We use Google Analytics (GA4) to track site usage, including pages visited, time on site, approximate location, device data, and referral sources. This data is used solely to analyze traffic patterns and improve site performance. These cookies run only with your explicit consent. For details on Google’s data processing, see: https://policies.google.com/privacy

  • Marketing cookies: We use the LinkedIn Insight Tag to measure the effectiveness of our marketing campaigns and determine if visitors arrived to the Website via LinkedIn advertisements. This data helps us evaluate professional outreach performance. These cookies are deployed only with your consent. For further details, see: https://www.linkedin.com/legal/privacy-policy

Third-Party Cookies & International Transfers

Some of our third-party service providers (Webflow, Cloudflare, Google, LinkedIn) are headquartered in the United States. This means that data collected via their cookies may be transferred to and stored on servers outside the European Economic Area (EEA).
‍
To ensure your data remains protected, we rely on the EU-U.S. Data Privacy Framework (adequacy decision) for transfers to certified organizations. For any providers not covered by an adequacy decision, we ensure that appropriate safeguards, such as Standard Contractual Clauses (SCCs) approved by the European Commission, are in place to maintain a level of protection equivalent to that of the GDPR.
