Email [email protected]Do I need an account to use Cambium?
Free use needs no account on either platform. New purchases require sign-in; existing App Store purchases can still be restored without an account. Signing in syncs your account Garden across supported devices. Guest plants stay separate until you add them.
What's included in the free plan?
On iOS and Android: 3 identifications, 2 diagnoses and 3 recovery re-checks per UTC month; 1 active Recovery Loop; up to 3 saved plants; toxicity warnings; and watering reminders.
What does Cambium Plus unlock?
Plus includes unlimited saved plants, history and Recovery Loops. Allowance plans include 30 identifications and 8 shared health analyses per UTC month; diagnoses and recovery re-checks share the health allowance. Earlier unlimited plans retain unlimited AI access. Annual is $24.99/year in the U.S. with a seven-day trial for eligible new subscribers. Founder’s Lifetime is $49.99 once in the U.S., available through December 31, 2026. Your app and store checkout show the product benefits, local price and trial eligibility before purchase.
How does plant identification actually work?
Each photo is sent to CambiumRelay, our server, which uses OpenAI’s image analysis to suggest an identification or assess visible health. Cambium does not identify plants locally on your device.
Is my data used to train AI models?
Cambium does not use your photos to train a model or sell your personal information. Submitted photos are processed by OpenAI under its API data policies, as explained in our Privacy Policy.
Does Cambium use ads or trackers?
Cambium has no advertising SDKs, third-party analytics SDKs or crash-reporting SDKs. Optional first-party aggregate product events can be disabled in Settings. Website analytics are described separately in our Privacy Policy.
How do I cancel my subscription?
On iPhone, use Settings → Manage subscription or your App Store account. On Android, use Settings → Manage purchase or Google Play → Payments & subscriptions → Subscriptions. Cancel through the store account used to buy it. Deleting a Cambium account does not cancel billing.
How do I restore a purchase on a new device?
Use Settings → Restore purchases with the store account used to buy it. For access on another platform, sign in with the same Cambium account associated with the purchase. If access is missing, contact support before buying again.
How do I export my data?
Use Settings → Export my data on iPhone or Settings → Export Garden on Android. Review the generated file before sharing it.
How does Garden sync work?
Sign in to the same Cambium account on each device. Account Garden sync starts automatically. Guest plants stay separate until you choose Add guest Garden to account. You can turn sync off in Settings; removing a Garden from one device keeps its cloud copy, while Delete Garden everywhere removes the synchronized Garden.
How do I delete my data?
Use Settings → Account → Delete Cambium account and confirm your identity. Garden controls let you remove an account Garden from one device or delete its synchronized copy. Guest Garden data can be deleted locally. Deletion does not cancel App Store or Google Play billing.
The camera won't open, or the photo picker isn't working.
For camera trouble, check Camera permission for Cambium in your device settings. The system photo picker does not require full Photo Library permission. If picking a photo still fails, restart the app and try another image.
Watering reminders aren't showing up.
Reminders are scheduled locally on both platforms and require notification permission. Check Cambium’s notification permissions and your device’s Focus, Do Not Disturb and battery settings.
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.
Allowance plans include 30 identifications and 8 shared health analyses each UTC month. Diagnoses and recovery re-checks share the health allowance. Earlier unlimited purchases remain unlimited. Check your plan in Settings and try Restore purchases if it is not recognized. Contact support if the allowance does not match the product you bought.
