Our code does not log your IP, and Google Cloud logging exclusions are configured so the platform's default access logs are not retained.pollen-proxy) for the same reason, with the same no-IP-logging configuration.Location button: if you tap the location pin next to the search box, your browser asks for your permission first — the site never requests your location on its own. Your coordinates are rounded to roughly 1 km inside your browser before use, are sent only to the same weather services listed above (exactly as if you had typed a city name), and never touch a server of ours. Note that your browser itself may use its vendor's location service (for example, Google's in Chrome) to work out your position. The "use my location automatically" setting only takes effect on visits where you have already granted permission.
Your preferences (dark mode, temperature units, time format, language, visual style, and section layout) are saved in your browser's local storage (not a cookie) so they persist between visits. Pollen data is also cached locally to reduce unnecessary API calls. You can clear all of this anytime by clearing your browser data.
