Strain Passport is a free, privacy-first cannabis journal that lives on your phone. Log every strain you try, rate your experience, and build a personal record of your cannabis journey — no account, no cloud, no tracking. Your data stays on your device. Free forever, works on any phone, no download required. I initially built this tool for myself, but I quickly realized others may find it useful, too. I'm happy and eager to share it with my peers in the cannabis / tech communities (and beyond).
