Privacy Policy

Transparency regarding data collection, cookie usage, advertising standards, and client-side processing on chunkbase.dev.

1. Overview

chunkbase.dev provides web-based seed exploration utilities, biome finders, and structure mapping tools for Minecraft players across Java Edition and Bedrock Edition. We are dedicated to maintaining user privacy and minimizing data collection. This privacy document details how our tools handle your data, our cookie consent framework, and our advertising practices.

2. Local Save Game Processing (level.dat)

When you use the "Load from save" feature on any of our seed tools, you are prompted to select a level.dat file from your local computer.

Zero Server Transmission: All level.dat and world save files are read, unpacked, and parsed entirely inside your web browser sandbox using local client-side scripts. Your world files, seed parameters, and player inventories are never transmitted across the network, never uploaded to our servers, and never stored externally.

3. Cookies, Consent Mode & The cc_v1 Storage Key

We employ a privacy-first consent implementation designed in compliance with regional regulations, including the European Union General Data Protection Regulation (GDPR) and UK data privacy standards.

When a visitor arrives from the European Economic Area (EEA), United Kingdom (UK), or Switzerland (CH)—identified via a local browser timezone check without geo-location tracking—the site activates Google Consent Mode v2:

  • Default Undecided State: Prior to any user decision, advertising storage and analytics storage signals are set to denied.
  • Acceptance (granted): If you choose "Accept" on our consent bar, the preference is recorded in your browser's localStorage under the key cc_v1 with value granted, and consent signals are updated accordingly.
  • Rejection (denied): If you choose "Reject" on our consent bar, your choice is saved in localStorage under cc_v1 with value denied, ensuring tracking and personalization cookies remain disabled.
  • Non-EU Visitors: Visitors connecting from outside the specified European regions run with default granted signals without encountering the consent prompt.

You can inspect or adjust your cookie preferences at any time by opening the consent dialogue through our Cookie settings dialogue or by using the Cookie settings link located in our footer.

4. Advertising

chunkbase.dev displays third-party web banner advertisements to subsidize server infrastructure, domain maintenance, and ongoing software updates.

Third-party advertising vendors and ad networks may serve advertisements on our web pages. In doing so, these third parties may deploy or recognize cookies, web beacons, and similar tracking technologies within their advertising iframes to measure campaign effectiveness, prevent fraudulent impressions, and deliver advertisements relevant to your browsing context.

All ad units adhere to the consent choices set via our consent bar and local storage signals. If you have denied cookie storage, ad networks operate under restricted, non-personalized configurations. We do not sell personally identifiable information to advertising vendors.

5. Anonymous Analytics

We may gather aggregated, anonymized metrics to evaluate technical performance, track server load, and identify which seed finders are most frequently accessed. These measurements do not contain personally identifiable information and are strictly suppressed when cookie consent is denied.

6. Local Browser Settings

In addition to the cc_v1 consent key, our interactive mapping tools save convenient interface preferences in your browser's localStorage. These include your recently entered seeds, active map layer visibility toggles, custom coordinate pins, and map zoom resolutions. These entries are stored exclusively on your device and are never transferred to third parties.
