Weathervane is a free, unofficial fan tool, not affiliated with or endorsed by ConcernedApe. Stardew Valley and its game art are © ConcernedApe LLC. Stardew Valley is a registered trademark of ConcernedApe LLC.
Game facts come from the game's own data files (Stardew Valley 1.6), with locations and descriptions from the community-maintained stardew-valley-data set.
Your data
Your save file is read in this browser and never uploaded. What Weathervane takes from it (your farm's name, your and your co-op partners' names, gold, items and progress) and anything you type is kept in this browser only: there are no accounts. To take your farms to another browser or device, use Back up & move on the Load a save page. To remove everything, delete your farms there, or clear this site's data in your browser's settings.
Feedback you send goes to the people who make Weathervane and is kept with Cloudflare, the site's host: what you wrote, its kind, the page, the game day when a farm is loaded, the version, your screen (phone or computer, its width, light or dark), the page's language and when it arrived. No name, no email address and no IP address is stored. When the form opens, Cloudflare Turnstile checks that the browser isn't a spam robot.
Plan and layout links carry only the plan, never names. Picture cards show your farm's name and gold, and only leave the page if you save or share them. The page's fonts and pictures come from this site. Only three things reach beyond it, each only when needed: a small tool that opens .zip saves (from cdnjs.cloudflare.com, only if you open a .zip), Cloudflare's spam check when you open the feedback form, and Cloudflare Web Analytics, which counts visits without cookies and without telling us who you are. If the page breaks, a short error report (the message, the page, the version and the browser's name) comes back to this site, with nothing about you or your farm.
Progress links and their picture carry only what you tick, with no names unless you switch them on, and nothing in them can be taken back once sent. The progress sits after the # in the link, so it never reaches this site's server.
