Our current technologies
Supabase Authentication
Supabase SSR authentication cookies keep signed-in sessions available and allow the server to validate the authenticated user. They are necessary for account access and are not used for advertising. See Supabase's privacy policy.
Mercidia workspace selector
The minsight_workspace_id cookie remembers the workspace the signed-in user selected. It is only a selector; workspace membership and role authorization are checked server-side for every request.
Vercel Speed Insights
When you allow performance measurement, Vercel Speed Insights receives limited technical performance information about page delivery. Mercidia does not load this component before your choice, and it is disabled when you reject optional technologies. See Vercel's privacy policy for its processing terms.
Change your preferences
You can reopen the privacy controls at any time. Your choice is stored in the necessarymercidia_privacy_consent cookie for up to 180 days, or until this policy version changes. You can also clear cookies in your browser settings.
California and other opt-out rights
Mercidia does not currently sell personal information or use advertising cookies. The opt-out control above rejects optional performance measurement and provides a direct way to exercise a no-sale or no-share choice if applicable law treats optional measurement as a regulated disclosure. We will update this policy before introducing advertising, retargeting, or other cross-site technologies.
