Terms and conditions

Purpose

These terms govern the use of the Geode application and the sale of the subscription offered within it. Using the app, with or without a subscription, means accepting them.

A Geode subscription gives you unlimited identifications. Without one the app still works: your free identifications, your collection and the sheets you have already obtained all remain available.

Prices are shown in euros including tax for France. The price that counts is the one displayed in the app at the moment you subscribe: Apple and Google adjust their price tiers by country and over time, and this page may lag behind them.

Nature of the service

Geode provides an automated identification for educational purposes, produced by an artificial intelligence model. The result is a probabilistic hypothesis: it is not a gemmological appraisal, a valuation, or a certificate of authenticity. Several decisive mineralogical tests — hardness, density, reaction to acid, magnetism — cannot be observed in a photograph, which is what the confidence rating shown in the app reflects.

The crystal-lore properties mentioned in the sheets are cultural and traditional in nature. They are in no way medical advice, a diagnosis or a treatment, and are no substitute for seeing a doctor.

Account and backup

A Geode account is free and optional. It is not part of the subscription and not a condition of it: the free identifications and the subscription both work without one. It exists to back up your collection so that it follows you from one device to the next.

Backing up photographs is a separate option, off by default, which you can switch on and off at any time in the settings.

Deleting your account does not cancel your subscription, and cancelling does not delete your account: the subscription is attached to your Apple or Google account, the Geode account to your collection. The two are managed separately, and the app points to where each is done.

No free trial

Geode does not offer a free trial that turns into a paid subscription. You get a number of complete identifications free of charge, renewed periodically, and then you decide. How many are left is shown in the app itself. Nothing is charged until you have explicitly subscribed.

Subscribing and payment

The subscription is bought and billed through the App Store (Apple) or Google Play, depending on your device; they are the sellers of the subscription. Payment is taken from the payment method attached to that account when you confirm the purchase. We never have access to your card details.

Automatic renewal

The subscription renews automatically at the end of each period, for the same duration, unless cancelled at least 24 hours before the current period ends. Renewal is charged within the 24 hours before the new period begins.

Cancelling

You can cancel at any time from the subscription settings of your Apple or Google account — the app's "Manage subscription" screen takes you straight there. Cancellation takes effect at the end of the period you have already paid for: access stays open until then, and nothing further is charged.

Deleting the app does not cancel the subscription, which is attached to your store account rather than to the device.

Deleting your Geode account does not cancel the subscription either: only the App Store and Google Play can do that. The account deletion screen says so and takes you to the management screen.

Right of withdrawal

The subscription is digital content supplied immediately. Under article L. 221-28 of the French consumer code, you waive your 14-day right of withdrawal as soon as you first use the subscribed service, which you expressly accept when subscribing.

Refund requests fall under App Store or Google Play terms, as they are the only sellers of the subscription. Write to us if you run into trouble: we will back your request with them.

Restoring purchases

A subscription you have already paid for can be restored free of charge on a new device, from the app's settings, provided you use the same Apple or Google account as when you bought it.

If you have a Geode account, signing in on the new device also attaches the subscription to that account. If a subscription bought before signing in does not follow, the app immediately offers to restore your purchases.

Changes to the service and to prices

Any price change is notified to you by the store at least 30 days in advance and applies only to subsequent periods; you can cancel free of charge before then. We may change features, without substantially reducing the essential benefits of a running subscription.

What the subscription does not guarantee

Identification relies on an artificial intelligence model and remains a probabilistic hypothesis. The subscription gives you access to the service, not to a correct answer: no warranty of identification accuracy is given, and a wrong identification does not entitle you to a refund. See "Nature of the service" above.

Intellectual property

The content of the Geode application, including its source code, user interface, text, illustrations, icons, and logo, is protected by intellectual property laws. Any reproduction, distribution, display, or reuse, in whole or in part, without prior written authorization is prohibited.

The photographs and other content that you create or import into the application remain your property. Geode does not claim any ownership rights over such content, except for the limited rights strictly necessary to process it and provide the service.

Liability

We do our best to keep the information accurate and current, without warranting that it is exhaustive. It is your responsibility not to handle, cut, heat, ingest or otherwise use a stone on the strength of an app identification alone: some minerals are toxic, friable, or hazardous to work.

Nor does the application permit or legitimise any collecting: gathering minerals is regulated, and in many protected areas and on private land prohibited.

Governing law and disputes

These terms are governed by French law. If something goes wrong, write to us first at identify-suite@revely.tech — most situations are settled in a couple of messages.

Because the subscription is sold by Apple and Google, refund requests fall under their respective terms.

Customer support

A question about your subscription: identify-suite@revely.tech. Geode is published by one person; we reply as soon as we can, usually within a few working days. See also the legal notice for publisher details.
