Cookie Policy
Last updated May 6, 2026
SDR to HDR uses a minimal set of cookies and similar technologies. We do not run advertising trackers, retargeting, or third-party social cookies.
1. Strictly necessary
These keep you signed in and remember your language: Supabase auth cookies (sb-access-token, sb-refresh-token), the NEXT_LOCALE locale cookie, and a small number of Next.js routing cookies. Without these the service does not work; they cannot be disabled while you are using SDR to HDR.
2. Analytics
We use Google Analytics 4 with IP anonymization to count visits and conversions in aggregate. You can disable this by using your browser's "Do Not Track" or by blocking GA in your privacy settings.
3. No advertising
We do not place advertising cookies, do not sell data to ad networks, and do not run cross-site retargeting.
4. How to disable cookies
Every modern browser lets you block or delete cookies. Note that blocking strictly-necessary cookies will sign you out and may break the app.
5. Retention
Session cookies expire when you close the browser. Persistent cookies (sign-in refresh, locale) live for at most 12 months.
