Answers to common questions below. Can't find what you need? Email us directly, or use Profile → Contact support in the app, which automatically includes your app version and platform so we can help faster.
Email [email protected]Do I need an account to use Cambium?
No. You can scan plants and keep a local Garden without signing in. Signing in with Apple or Google is optional and enables private sync across devices.
What's included in the free plan?
3 scans and 1 full diagnosis per month, up to 3 saved plants in your Garden, toxicity warnings (always free, never paywalled), and watering reminders.
What does Cambium Plus unlock?
Unlimited scans and diagnoses, unlimited saved plants, and unlimited saved scan and diagnosis history. Available as an annual subscription ($24.99/year) or a one-time Founder's Lifetime purchase ($49.99, while available).
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 → Profile → Manage store subscription, which opens your Apple or Google subscription settings directly. You can also cancel anytime from the App Store or Google Play app itself.
How do I restore a purchase on a new device?
Open Cambium → Profile → Restore purchases.
How do I export my data?
Open Cambium → Profile → Export my data to share a JSON file containing your plants, care profiles, scans, diagnoses, treatment steps, and recovery history.
How do I delete my account and data?
Account deletion is currently handled as a request rather than an in-app button. Visit our account deletion page for how to request it and exactly what gets removed.
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 Profile → Restore purchases. If the limit still shows, contact support.
