Cookie Notice
Last updated: 10 July 2026
OPTICGAMMA uses cookies and similar technologies (localStorage, sessionStorage). This notice explains what we use and why.
Strictly necessary (always on)
| Name | Purpose | Lifetime |

sb-access-token, sb-refresh-token | Supabase session | 7 days |
opticgamma_uid_local | Local journal anonymous id (until you sign in) | Until cleared |

Analytics (off by default; opt-in)
OPTICGAMMA does not load third-party analytics until you opt in via the cookie banner. When you opt in, we load Google Analytics 4 (Google LLC, measurement ID G-CB5VTDKGKG; cookies prefixed _ga, lifetime up to 13 months) to understand which pages and workspaces are used. We do not use it for advertising or remarketing, we do not enable cross-site tracking signals, and we do not send it your name, email, or mobile number. Decline — or simply ignore the banner — and it never loads. You can change your choice anytime in Settings → Privacy.
Separately, we use Vercel Web Analytics to count page views. It sets no cookies and stores no personal data or persistent identifiers (visitors are approximated with an anonymous hash that resets daily and cannot follow you across days or sites), which is why it does not require an opt-in. It cannot identify you and is not shared with advertisers.
Third-party services
We never embed third-party advertising trackers. Sentry's session-replay is disabled. Razorpay sets its own cookies on its checkout pages — those are governed by Razorpay's cookie policy. Google Analytics (above) loads only after you opt in.
Manage your preferences
- In-app: Settings → Privacy — cookie preferences (allow or decline analytics anytime)
