Introduction

Welcome to the Weerstation Griftsemolen dashboard. Privacy is important to us. This statement clearly explains what data we collect and how we handle your visit to our website.

💡 Spoiler: We do not use external tracking or advertising cookies. With your consent, we anonymously measure visitor behaviour for UX improvements — fully privacy-friendly.

Data Collection

Weather Data

Our weather station collects meteorological data such as temperature, humidity, wind speed, precipitation, air pressure and air quality (AQI, PM2.5, PM10, NO2). This data is completely anonymous and does not contain any personal information.

Anonymous
Visitor Statistics & Application Logs

For privacy-friendly website improvements we collect minimal, anonymised statistics:

  • Browser type and version (for compatibility)
  • Operating system (Windows/Mac/Linux/iOS/Android)
  • Device type (Desktop/Mobile/Tablet)
  • Country and city (via geo-IP lookup)
  • Traffic source category (Direct/Search engine/Social/Link, no specific URLs)
  • Visited page (path name only, no query parameters)
  • Time of visit (for usage patterns)
This minimal data is processed locally in aggregated statistics. IP addresses are anonymised immediately upon collection. Bots are automatically filtered out (95%+ accuracy). No cross-site tracking, no external analytics services.
Application Logs
Technical logs are stored in a structured format (Monolog JSON format) at WARNING+ level to limit volume. Contains only operational events (errors, warnings, critical issues), no routine database connections. Automatic rotation after 7 days, storage on Dutch servers.
What we do NOT collect
  • Names, emails, phone numbers
  • Addresses or other personal data
  • Social media integration
  • External tracking
  • Marketing cookies
  • Third-party analytics

We may update this privacy statement to reflect new features or legal requirements. Important changes will be indicated by the "Last updated" date at the top of this page.

Summary
Privacy-first approach: This weather station dashboard collects no personal data, uses no tracking cookies, and shares no information with third parties. We focus purely on displaying local weather data with minimal data footprint.

Privacy updates: Improved data anonymisation, minimal data collection, local storage, air quality monitoring without personal data, and theme preference storage ensure an optimal privacy experience.

API Consolidation (December 2025): Complete migration to Open-Meteo as exclusive weather provider, removal of all legacy APIs (MeteoServer, OpenWeatherMap, Weerlive) for simplified and more privacy-friendly architecture without unnecessary external dependencies.

Security improvements: Extended InputValidator class for type-safe validation, stricter session security with stricter regex, coordinate validation for geographic data, secure cache key generation, rate limiting protection, updated CSP policy, and improved error logging ensure optimal security and system performance.
