Privacy Policy
Last Updated: March 2026
The short version: Green Luzern does not collect, store, or sell your personal data. Your location is only ever used locally on your device to calculate directions. We use no advertising trackers or cookies.

1. Introduction

Welcome to Green Luzern. This Privacy Policy explains how we handle your information when you use our interactive sustainability map. We are committed to protecting your personal information and your right to privacy.

2. Information We Collect

Location Data: If you grant permission, Green Luzern briefly accesses your device's geolocation (GPS) when you click "Directions" or "Locate Me". This data is processed locally within your browser and sent directly to our open-source routing provider (OSRM) solely to calculate your route. We do not store, log, harvest, or track your physical location on any servers we own or operate.

Local Storage: We use your browser's localStorage to save your preferences (such as your preferred map layer style). This data never leaves your device and is not used for tracking or profiling.

No Account Required: Green Luzern does not require you to register, log in, or provide any personal information such as your name or email address.

3. Third-Party Services

To provide high-quality map rendering and routing, Green Luzern relies on the following third-party open-source services. These services operate under their own independent privacy policies and may log anonymous web traffic data (such as IP addresses) when serving content to your browser:

4. Cookies & Analytics

Green Luzern does not use advertising cookies, cross-site tracking pixels, or third-party analytics platforms (such as Google Analytics). We do not sell or share any data with advertisers or data brokers.

5. Data Sharing

We do not sell, rent, or share your personal data with any third parties for commercial purposes. The only data transmission that occurs is between your browser and the open-source map tile and routing servers listed above, which is necessary to display the map and calculate directions.

6. Your Rights

Since we do not store personal data, there is nothing for us to delete or correct on our end. If you wish to clear any locally stored preferences, you may clear your browser's local storage at any time through your browser's developer tools or settings.

7. Your Consent

By using Green Luzern, you consent to this Privacy Policy. Refusing location permissions will disable the routing functionality, but all other map features remain fully accessible without sharing any location data.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected on this page with an updated "Last Updated" date. We encourage you to review this page periodically.
