Common questions
Do I need an account?
No. Tap Explore as a guest on the first screen to browse the catalog, identify plants and use the map. Signing in — with Apple or Google on iPhone, with Google on Android — keeps My Herbs, your scan history and saved recipes in your account, so they come back on any phone you sign in on. On iPhone, adding herbs to My Herbs and saving recipes need an account; on Android they are kept on the phone until you sign in.
What is free, and what does Premium add?
The catalog, the map, My Herbs and sync are free. The free version also includes a few plant identifications and AI recipes — a set number in total, not a daily allowance. Premium is a monthly or yearly subscription that removes those limits and the ads, and unlocks nutritional data, side-by-side herb comparison and the full results of finding herbs by their components.
I bought Premium and it is not unlocked.
Open Profile → Settings → Subscription and tap Restore Purchases, signed in to the same Apple ID or Google account you bought Terra Premium with. Premium belongs to that store account, so it does not move between iPhone and Android. If it still does not appear, email us with the date of purchase.
Can I move my herbs to a new phone?
Yes, if you are signed in. Sign in on the new phone with the same account, and My Herbs, your scan history and saved recipes come back. The AI chat and the app settings stay on the old phone. To move between iPhone and Android, use a Google account: Android has no Sign in with Apple.
Terra named the wrong plant, or says it is not a herb.
Try again with a clearer photo: good light, one plant in view, its leaves or flowers filling the frame. AI identification can be wrong, so compare the result with the photos and description in the catalog before you trust it. A plant that is not in the Terra catalog has no page to open.
Can I identify a photo I already took?
Yes. On the identification screen, choose a picture from your gallery instead of taking a new one. Terra does not need access to your photo library for this: only the picture you choose is shared with the app.
Does Terra work offline?
Partly. The herb catalog downloads on first launch, and after that you can browse it without a connection. Identification and AI recipes need the internet, because the photo or request is processed by Google Gemini. If the catalog did not load, connect and tap Refresh Herb Catalog in Profile → Settings.
The map cannot find me.
Terra uses your location only on the map: to centre it on you and to suggest herbs for your climate zone. Allow location access for Terra in your phone's settings, or simply move the map to your area — Discover herbs then uses the centre of the map instead.
Does Terra tell me if a plant is poisonous?
No. Terra has no toxicity rating, and identification can be wrong. Many plants have toxic look-alikes: never eat, drink or apply a plant identified only by the app — always confirm it with a qualified expert.
Why are my scan photos in my gallery?
On Android 10 and later, Terra saves the photo of each scan to Pictures/Terra on your phone. They are ordinary photos, and you can delete them like any other. Terra on iPhone does not save scan photos.
How do I delete my Terra account?
Sign in, then open Profile → Settings: on iPhone the button is under Account, on Android under Manage Account. Tap Delete Account and confirm; the app may ask you to sign in once more first. Your account and everything synced to it are erased. If you cannot use the app, email us from your account's email address and we will delete it within 7 business days.
Does Terra collect any data?
When you sign in, your account, My Herbs, scan history and saved recipes are stored with Google Firebase. The photos and requests you submit are sent to Google Gemini to produce the result. Terra also collects usage analytics and crash reports so faults can be found and fixed, and shows ads to users without Premium. The privacy policy says exactly what is collected and who processes it.
Safety
Terra provides general educational information about plants and their traditional and researched uses. It is not medical advice, diagnosis or treatment, and it is not a substitute for care from a qualified healthcare professional. Do not use herbal preparations while pregnant or breastfeeding, when giving them to children, or alongside prescription medication, without first consulting a doctor or pharmacist. Herbs can interact with medicines and can cause allergic reactions. If you think you may have a medical emergency, contact your local emergency services immediately.
