Privacy policy

Last updated: November 1, 2026

Overview

At mcseedmap.dev, we are committed to protecting your privacy. This website is designed as a client-side web utility for Minecraft players. All world map calculations, biome estimations, structure finding, and coordinate generations are executed locally on your device via WebAssembly.

Data We Do Not Collect

We do not collect, store, or sell any personal information. Specifically:

  • No seed data logging: The seeds, coordinates, dimensions, and settings you enter are processed only within your web browser and are never transmitted to or logged by our servers.
  • No user accounts: We do not offer registration, user profiles, or account logins.
  • No sale of personal data: We do not sell your personal data or maintain personal user profiles.

Cookies and Tracking Technologies

We do not set tracking cookies ourselves. The site keeps your settings in your browser's local storage, and our advertising partner may set its own cookies (see Advertising below):

Local Storage

mcseedmap.dev uses browser local storage (localStorage) solely to remember your chosen user preferences across visits. Specifically, we store the following keys:

  • theme: Interface theme (light or dark mode)
  • edition: Selected Minecraft edition (Java or Bedrock)
  • version: Selected Minecraft version identifier
  • dim: Selected dimension (0 for Overworld, -1 for Nether, 1 for The End)
  • seed: Last entered seed text
  • mapSettings: Map display preferences (terrain estimation, contour lines, coordinate grid, active markers)

This data remains strictly on your device and can be cleared at any time through your browser settings.

Analytics & Delivery

Operational delivery and DDoS mitigation are provided via Cloudflare edge routing without personal tracking.

Advertising

A third-party advertising partner shows ads on this website to pay for hosting. Ads load for every visitor; the partner may set its own cookies or similar identifiers and read device details such as screen width to choose an ad size. The cookie banner records your choice for analytics and ad personalisation signals; it does not block the ads themselves. You can change that choice at any time with the Cookie settings link in the footer. We never send world seeds, map settings or personal profiles to advertising partners.

Hosting & Security

This website is hosted on Cloudflare's global content delivery network. Cloudflare may process transient operational logs (such as IP addresses and request headers) strictly for security purposes, bot mitigation, and DDoS prevention.
