Cookies are small text files that a website stores on your device when you visit. They allow the site to remember information about your visit — such as whether you're logged in — so you don't have to re-enter it every time.
In addition to HTTP cookies, web browsers also provide localStorage — a way to store data on your device that persists between sessions but is never sent to the server as part of a network request. This page covers both HTTP cookies and browser localStorage items that CalendarPipe uses.
CalendarPipe uses a minimal set of cookies and browser storage — only what is necessary to keep the service working and to remember your preferences.
| Cookie / Storage | Purpose | Duration | Type |
|---|---|---|---|
sb-[ref]-auth-token | Authenticates your session with CalendarPipe. Set and managed automatically by Supabase. The exact cookie name includes your project reference ID. | Session (JWT-based) | Essential |
csrfSecret | Protects form submissions from cross-site request forgery (CSRF) attacks. | Session | Essential |
theme(localStorage) | Stored in browser localStorage, not sent as an HTTP cookie. Used only client-side to remember your light or dark mode preference. | Persistent (no expiry) | Preference |
Supabase automatically manages session cookies for authentication. The exact cookie name includes your project reference ID (e.g., sb-[ref]-auth-token).
CalendarPipe does not currently use any analytics, tracking, or advertising cookies. We do not collect behavioural data about how you use the service.
We may introduce privacy-respecting analytics in the future to understand how CalendarPipe is used and to improve the service. If we do, we will:
You can manage and delete cookies through your browser settings. Most browsers allow you to:
Essential cookies (authentication and CSRF protection) are required for CalendarPipe to function. Clearing or blocking them will sign you out and prevent you from signing back in until a new session cookie is set.
To clear your theme preference, open your browser's developer tools, navigate to Application → Local Storage, and delete the theme key. Doing so will reset your preference to your system's default light or dark mode setting.
