No account needed
The site has no account system, advertising scripts, analytics trackers, email signup or contact form. Fonts, photos, search data and page assets are served with the site.
Search and your saved garden
City and state searches are matched in your browser against downloaded location data. ZIP-code lookup downloads a data file for the first two digits of the code. When you open a ZIP result, the code appears in the page URL and may therefore appear in hosting requests.
Saving a garden is optional. Its city identifier is stored in your browser under usfrostdates-garden. This saved value is not uploaded to an account or database. Your browser may retain it until you clear it. Remove it using the button below or your browser settings.
Planting calculations
Crop names, dates and planner settings are processed in your browser. Calendar files are generated on your device. We do not ask for a street address or precise device location.
Hosting and technical requests
The public site is configured for hosting through Cloudflare. Delivering and protecting pages involves processing technical request information such as your IP address, browser information and the requested URL. This is separate from the garden preference stored locally in your browser. See Cloudflare’s privacy policy for its processing practices.

There are currently no affiliate tracking links, paid placements or third-party advertising on USFrostDates.
Data and limitations
Dates are historical planning references, not current forecasts or a guarantee against frost. Data sources, licenses and limitations are listed in our methodology and credits.
