Tools used
DataFast and Vercel Analytics measure home page traffic. Vercel Speed Insights measures performance. These optional tools are off by default and load only after consent for their purpose. They are not loaded on legal, email confirmation or password reset pages.
Accept, reject or change your mind
Accept or reject both purposes, or choose each separately. Cookie settings lets you change your choice. Rejecting does not prevent browsing or joining the waitlist. Withdrawal reloads the page to stop loaded scripts. Global Privacy Control disables optional tools.

The relevant recipients are DataFast and Vercel. The Privacy Policydescribes your rights and the controller’s contact details.
The cookie-based DataFast script processes visit identifiers, IP address, browser, device and page activity. Its data processing agreement describes infrastructure mainly outside the EU, including the United States, and does not specify a single numerical retention period for paid subscription analytics.
According to its documentation, Vercel Web Analytics uses a visitor hash whose session is discarded after 24 hours. This is not the retention period for statistics. Typoly restricts Vercel events to the home page and removes query parameters from their URL. Speed Insights collects performance measurements after separate consent.
The DataFast DPA describes collected categories and infrastructure including the United States. It does not specify one numerical retention period for long-term customers: cookie lifetimes above are not statistics retention periods. See also the Vercel Analytics privacy documentation.
