WHO BUILDS THIS Yoi Bonsai is built and maintained by Lonnie Bowling — a working bonsai enthusiast. It is run as a service to the bonsai community, not a profit-maximizing business: the best possible platform, a reasonable subscription to develop and maintain it, and a contribution to the hobby and the art. These choices are deliberate: • Ichiba charges zero fees. Sellers keep 100% of the sale. • Subscription fee held or lowered as the goal — never raised just to chase profit. • No ads. No tracking pixels. No selling your data — ever. • One-tap export of every tree, log entry, and reminder, plus bulk photos at original quality. • Real questions reach a real person. 3–5 business days, often faster. • If the app is ever discontinued, you get 90 days notice and a final export. Cancel anytime through your Google Play subscriptions. Auto-renews unless cancelled. ——— Terms of Use (EULA): https://yoibonsai.com/terms Privacy Policy: https://yoibonsai.com/privacy
