Settings, data and privacy

Everything here is stored in this browser only. Export makes a file you control; import restores it on any device.

Export

Downloads a JSON file with all plans, seed inventory, logs and preferences.

Import

Choose a file exported from Garden Planner. The file is validated before anything is written.

Import mode

Clear local data

Removes plans, seeds, logs, task completion and your saved location from this browser. Export first if you want to keep them. This cannot be undone.

What is stored where

  • IndexedDB (garden-planner): plans, seeds, logs.
  • localStorage: region preference and frost dates, task completion, last-export time.
  • Service worker cache: pages and data for offline use.

No accounts, no analytics, no server. Privacy
