Cookies

We use cookies to collect information about ChainSec's users and website visitors. Cookies help us understand your preferences and gather data on user interactions to improve future experiences and tools. Read more about our Cookie Policy here.

Analytics — PostHog

If you accept analytics cookies, we use PostHog (PostHog Inc., 965 Mission Street, Suite 550, San Francisco, CA 94103, USA) to analyze how visitors use our website. PostHog processes data on our behalf as a data processor under a Data Processing Agreement. Data is stored on PostHog's EU servers (eu.posthog.com) and is not transferred outside the EEA.

To reduce the risk of requests being blocked by browser extensions, we route PostHog traffic through a reverse proxy on our own domain (chainsec.se/ingest). No data is stored on our servers — the proxy only forwards requests to PostHog EU.

PostHog does not collect IP addresses (IP recording is disabled). Session recordings, if activated, mask all input fields. Analytics data is only collected after you have given explicit consent via our cookie banner. You can withdraw consent at any time by clicking "Cookie settings" in the footer.

For more information about PostHog's data handling, see posthog.com/privacy.

Review of the Privacy Policy

ChainSec may update these terms periodically. Customers will be notified of significant changes and may terminate the agreement if they do not accept them. Continued use of the Website or services after updates constitutes acceptance of the new terms.
