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.
We do not require sign-in. We do not run analytics or advertising scripts in the application code. We are not affiliated with Fisch, Roblox, or fischipedia.
What we collect
We do not operate accounts or intentionally collect personal information (name, email, Roblox username, etc.) through this calculator.
- 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. The app does not use cookies or localStorage for this.
- Hosting logs — if this site is deployed (e.g. Vercel), the host may log IP address, user agent, and requested paths per their own policy. That is outside the calculator code.
Third-party services
Your browser may contact:
- This site — HTML, JavaScript, and
/data/*.json files from the same origin. - static.wikitide.net — thumbnail 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.
- ko-fi.com — optional support button in the footer; loads a small image from Ko-fi's CDN. Payment pages open only if you click the button.
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.
- Clear browser history or cache if you want to remove stored data.
- Block third-party domains with privacy tools; icons may not load but chances can still calculate from local JSON.
