Privacy
GrowGuide keeps data collection small. There are no accounts, no cookie banner, and nothing to opt out of except analytics.
Saved on your device
Your setup, garden profile, saved advice, and completed tasks stay in this browser. Clearing your browser data removes them.
What leaves your browser
Postcode validation sends the exact postcode you enter to api.postcodes.io, which returns a region and coordinates. Those coordinates are rounded to about a kilometre before the forecast request goes to the Met Office, and map tiles are fetched through this site rather than by your browser, so OpenWeatherMap never sees you directly.
Anthropic receives bounded region, garden, and derived-weather context when you ask for growing advice. It does not receive your exact postcode or coordinates.
Analytics and your choices
We use anonymous, cookieless Vercel Web Analytics to see which pages are useful. You can block it without losing any GrowGuide feature. GrowGuide creates no user accounts, sells no data, and runs no advertising trackers.
