Overview

Fisch Chances (https://fischchances.com) is a fan-made Fisch catch chance calculator. It estimates catch probabilities using data from fischipedia.org. Calculations run in your browser after static data files load.

Using the calculator does not require sign-in or an account. When deployed on Vercel, we use Vercel Analytics for anonymous page-view counts only — no advertising scripts and no personal profiles. Optional features (issue reports and a private admin panel) use Supabase and are described below. We are not affiliated with Fisch, Roblox, or fischipedia.

What we collect

Normal calculator use does not ask for your name, email, or Roblox username. The following applies when you browse and calculate chances:

  • Calculator settings — encoded in the page URL (pool, rod, bait, weather, luck, events, and similar). Anyone with the link can see those settings. Your browser may store the URL in history.
  • Cached files — JSON bundles and images may be stored in your browser cache like any static website.
  • In-memory data — loaded JSON is kept in memory during your visit to avoid repeat downloads. This cache is not written to cookies or localStorage.
  • Anonymous analytics — when deployed on Vercel, Vercel Analytics records page views (path and referrer metadata). It does not use cookies for tracking and does not tie visits to accounts or calculator settings.
  • Hosting logs — if this site is deployed (e.g. Vercel), the host may also log IP address, user agent, and requested paths per their own policy. That is outside the calculator code.

Issue reports (optional) — if you choose Submit report in the report dialog, we store what you send in our Supabase database: your description of the issue and expected behavior, optional notes, a share link that encodes your calculator setup, a snapshot of results and status at submit time, and the game/data version labels shown in the app. You do not need to provide an email or account to submit. Do not include personal information in the text fields unless you are comfortable with the site maintainer reading it for triage.

Admin sign-in (optional) — the private admin panel is for the site maintainer only. If you sign in with a magic link, Supabase processes your email address, issues a session, and stores session data in your browser (localStorage). Only email addresses on an allowlist can access admin features. The admin UI masks your email in the header (e.g. *******@gmail.com).

How we use and keep data

  • Issue reports are used to investigate calculator bugs and data mistakes. They are visible only to the allowlisted admin, not to other visitors.
  • Reports are kept until the maintainer deletes them or updates their status (open, triaged, resolved). There is no automatic expiry.
  • Admin sessions last until you sign out or the session expires per Supabase's defaults.
  • To ask about a report you submitted or to request deletion, contact us using the details in the Contact section below.

Third-party services

Your browser may contact:

  • This site — HTML, JavaScript, and /data/*.json files from the same origin.
  • static.wikitide.net — full-size icon images for fish, rods, baits, enchants, and weather (wiki CDN).
  • Fonts — Source Sans 3 is bundled with the app at build time (no runtime request to Google Fonts).
  • fischipedia.org — only when you click a fish wiki link; not used to run the math.
  • vercel.com — Vercel Analytics (when deployed) for anonymous page-view statistics. See Vercel's analytics docs.
  • supabase.com — when issue reporting and/or admin sign-in are enabled, your browser sends report submissions and authentication requests to our Supabase project (hosted by Supabase). See Supabase's privacy policy.
  • ko-fi.com — optional support link in the credits menu; loads a small image from Ko-fi's CDN. Payment pages open only if you click the link.

Those services may receive standard request metadata (IP, user agent, referrer). Their policies apply separately.

Your choices

  • Share links carefully — URLs can reveal detailed setups.
  • Issue reports are voluntary — use Discord from the report dialog if you prefer not to store data on Supabase.
  • Admins can sign out from the admin panel to end the Supabase session in that browser.
  • Clear browser history, cache, or site data if you want to remove stored URLs, cached files, or admin session tokens.
  • Block third-party domains with privacy tools; icons may not load but chances can still calculate from local JSON. Blocking Supabase will disable issue reports and admin sign-in.

Data licensing

Maintainer data refresh (scrapers, build scripts) runs at build time on developer machines, not in visitors' browsers during normal use.
