Cookie Policy (Fastyl.ink)

Last updated: March 9, 2026

This Cookie Policy explains how this website (“we”, “us”) uses cookies and similar technologies when you visit and use our site.

What are cookies?

Cookies are small text files stored on your device (computer, phone, tablet). They help websites function, keep you signed in, secure forms, and remember preferences.

Cookies we use (based on the current site code)

1) Strictly necessary cookies (essential)

These cookies are required for core site features and security. Disabling them may prevent the site from working.

Authentication cookies (ASP.NET Core Identity)
  • Purpose: keep you logged in; support “Remember me”; protect your account session.
  • Typical names: .AspNetCore.Identity.Application (and related Identity cookies).
  • When set: when you sign in / use account features.
Session cookie (ASP.NET Core Session)
  • Purpose: store short-lived state while you use the site (for example, workflow selections and which profile context is active).
  • Typical name: .AspNetCore.Session.
  • When set: while using features that depend on session state.
Anti-forgery / CSRF protection cookie
  • Purpose: protect forms and POST requests from cross-site request forgery (CSRF).
  • Typical names: .AspNetCore.Antiforgery.* plus a matching request token in forms.
TempData “flash message” cookie
  • Purpose: show one-time messages (for example success/error messages) after a redirect.
  • Typical name: .AspNetCore.Mvc.CookieTempDataProvider.
“Unique click” cookie for short links
  • Purpose: help count a short-link click only once per browser within a time window, to reduce repeated counting from the same device.
  • How it works: when a short link is opened, the site may set a cookie named as the link’s numeric id (example: \"123\"), with value \"1\".
  • Lifetime: expires after about 24 hours.
  • Flags (as coded): HttpOnly (not readable by JavaScript) and marked “Essential”.

2) External login / third-party authentication cookies

If you choose to sign in using a third-party provider (e.g., Google sign-in is enabled in the site configuration), login flows may involve cookies used to complete authentication. Those cookies may be set by us (to manage the external sign-in handshake) and/or by the provider under their own policies.

How to manage cookies

You can control cookies through your browser settings (block, delete, or clear cookies). If you block essential cookies, parts of the site (login, forms, and some features) may not work properly.

Changes to this policy

We may update this Cookie Policy when our features or cookie usage changes.
