FAQ

Is it really free?
Yes. Up to 7 plants on Free, with every feature unlocked. The only ad is a single slot at the bottom of the plant list — never inside emails or between cards.
How is my data protected?
Supabase Row Level Security ensures only you and your invited family can read your data. Photo EXIF location is stripped at upload. Full details in the Privacy Policy.
Is canceling easy?
Yes. One tap from Settings. You keep access through the end of the billing period.
Does it work on iPhone and Android?
Yes. Open in Safari (iPhone) or Chrome (Android), then "Add to Home Screen" — it behaves like a native app. Push notifications work on iOS 16.4+ and on Android Chrome.
How does family sharing work?
Send an invite link. Once joined, every watering is tagged with who did it, so the "did you already?" texts can stop. Up to 5 members free per household.
