Surf Online uses cookies and similar technologies on Meridian (meridian.surf) to operate the Service, keep you signed in, remember preferences, and — only with your consent — measure product usage and attribute referrals.
Cookies are small text files stored on your device. We also use local storage and session storage for similar purposes.
Strictly necessary cookies. These are required for Meridian to work and do not require consent:
__session: short-lived access token (httpOnly) for authenticated requests.__refresh: refresh token (httpOnly, limited path) to renew your session.__session_handle: identifies your Convex session for real-time dashboard features.
Blocking these cookies may prevent you from signing in or using the dashboard.
Functional preferences (non-tracking). We may store preferences such as theme, builder settings, and UI state locally to improve your experience. These preference stores are not used for advertising.
Marketing / attribution — consent required. Affiliate referrals use a signed __affiliate_ref cookie (30-day attribution window) when you arrive through a referral link. This cookie is not strictly necessary. We set or read it for attribution only after you consent via our cookie banner (or equivalent preference center). You can withdraw consent at any time under Account → Privacy & security or the banner preferences.
Analytics — consent required. Meridian uses first-party product analytics (PostHog, proxied at /ingest) to measure performance and improve the UI. Analytics scripts and non-essential analytics cookies/events load only after you consent.
- We do not run product analytics by default.
- Rejecting analytics is as easy as accepting; choices are not pre-ticked.
- You can change your mind anytime from the site notice or Account → Privacy & security.
- We do not use third-party advertising cookies on the dashboard, and we do not sell cookie data.
Global Privacy Control and Do Not Track. If your browser sends a Global Privacy Control (GPC) signal, we treat it as an opt-out of product analytics (and we will not set analytics until you later give affirmative consent through our banner, if we offer that override). We also respect an explicit analytics opt-out stored in your Meridian account preferences. We may still use strictly necessary cookies to operate the Service.
Your choices. Most browsers let you block or delete cookies. Essential cookies are required for core features. For analytics and affiliate attribution, use our cookie banner or Account → Privacy & security. Withdrawing consent does not affect the lawfulness of processing before withdrawal.
