How it works
Everything you enter is stored in your browser’s localStorage — a small private storage area on this device. Pot and Plot never sees it, and the tool works offline. Your tests stay saved until you clear them (or clear your browser data). Private or incognito windows may discard them when closed. Export downloads a backup file you can keep or move to another device; Import restores one.
Typical seed longevity figures come from published Extension guidance and describe fresh, well-stored seed under typical conditions — your actual results depend on storage, so trust your own test numbers first.
