Answers to common questions below. Can't find what you need? Email us directly, or use Settings → Contact support in the app, which includes your app version and platform so we can help faster.
Email [email protected]Do I need an account to use Cambium?
No. Cambium has no sign-in or account system. Your Garden, photos, notes, and recovery history stay on your iPhone unless you explicitly export them.
What's included in the free plan?
3 identifications, 2 full diagnoses, and 3 recovery re-checks per month; 1 active recovery plan; up to 3 saved plants; toxicity warnings; and watering reminders. Enough to follow one plant through a full recovery before deciding whether to upgrade.
What does Cambium Plus unlock?
Unlimited identification, diagnoses, saved plants, history, recovery plans, and guided re-checks. Annual is $24.99/year with a 7-day trial for eligible new subscribers. Founder's Lifetime is $99 once and is available through December 31, 2026. Your App Store shows the local price and eligibility before purchase.
How does plant identification actually work?
Every photo you scan is sent from the app to CambiumRelay, our server, which uses OpenAI's image analysis to identify the plant and assess its visible health. This happens for every scan — Cambium does not identify plants locally on your device.
Is my data used to train AI models?
No. Cambium does not use your photos to train any model, and we don't sell your personal information.
Does Cambium use ads or trackers?
No. Cambium has no advertising SDKs and no third-party analytics or crash-reporting SDKs.
How do I cancel my subscription?
Open Cambium → Settings → Manage subscription, which opens your Apple subscription settings directly. You can also cancel anytime from the App Store app itself.
How do I restore a purchase on a new device?
Open Cambium → Settings → Restore purchases.
How do I export my data?
Open Cambium → Settings → Export my data to share a JSON file containing your plants, photos, care profiles, scans, diagnoses, treatment steps, and recovery history.
How do I delete my data?
Cambium has no account or cloud Garden. Open Cambium → Settings → Delete all local data. You can choose whether to reset the anonymous monthly-usage identity too.
The camera won't open, or the photo picker isn't working.
Make sure Cambium has Camera and Photo Library permission in your device Settings → Cambium. If you denied permission at first launch, you need to enable it manually there.
Watering reminders aren't showing up.
Reminders are scheduled locally on your device and depend on your device's notification permission. Check Settings → Notifications → Cambium is allowed, and that Do Not Disturb or a Focus mode isn't silencing them.
A scan or diagnosis failed, or took too long.
This is usually a network hiccup or a temporary issue reaching our analysis service. Check your connection and try again. If it keeps happening, contact support with your app version so we can look into it.
I hit a monthly limit but I'm subscribed to Cambium Plus.
Force-quit and reopen Cambium so it can re-check your subscription status, then try Settings → Restore purchases. If the limit still shows, contact support.
