Plant identification model - licence terms

Last updated: 2026-05-23

The neural-network model that powers plant identification inside the Raychis app is the proprietary work of TerraRoxoAI. This page sets out what you may and may not do with it. Every shipped copy of the model carries embedded provenance metadata that lets us identify it if found in the wild.

1. Ownership

The plant identification model bundled with the Raychis app - an EfficientNet-B2-based multi-task neural network with a 256-dimensional embedding head for species lookup - is the proprietary work of TerraRoxoAI. The model, its weights, its training data, and the surrounding inference contract are protected by copyright and database-right law as applicable. Nothing on this page transfers any of those rights to you.

2. Permitted use

You may install and use the model as a built-in component of the official Raychis app distributed through the Apple App Store or Google Play. The model is shipped to your device for the sole purpose of running on-device plant identification within Raychis. No other use is permitted by default.

3. Prohibited use

Without prior written permission from TerraRoxoAI, you may not:

• extract the model files from the Raychis app bundle, by any means;
• redistribute the model, in whole or in part, with or without modification;
• embed the model in any other application, service, or product;
• expose the model through an API, web service, or any other public or private endpoint;
• reverse-engineer, decompile, or disassemble the model for the purpose of producing a competing product;
• use the model, or its outputs, as training data, fine-tuning data, or distillation supervision for another model intended to compete with Raychis.

4. Provenance and identification

Every copy of the model that ships with Raychis carries provenance metadata embedded directly into the model file: the company (TerraRoxoAI), the product (Raychis), the model identifier, the release version, the git commit identifying the exact source code that produced it, the build timestamp, and the SHA-256 of the source training checkpoint. In addition, TerraRoxoAI records a per-release cryptographic fingerprint of the model's behaviour on a private set of synthetic inputs.

We reserve the right to verify that any third-party machine-learning model alleged to identify plants - whether obtained from a competitor app, a web service, or a research dataset - is or is not a copy of ours, including by running paired-cosine comparisons against our archived fingerprints. The presence of our provenance metadata, or a fingerprint match against one of our archived releases, is taken as prima facie evidence that a model originated from us.

5. Trademark

"Raychis" and "TerraRoxoAI" are trademarks of TerraRoxoAI. Use of these names other than in plainly accurate factual reference (for example, "compatible with the Raychis app") is not permitted.

6. No warranty

The model is provided as an integral part of the Raychis app. As set out in our terms of service, the app and its model are provided "as is" with no warranties. The licence terms on this page do not create any warranty.

7. Termination

Any use of the model outside the permitted-use section above terminates this licence automatically, without notice. On termination, you must cease all use of the model and destroy any copies you hold.

8. Governing law

These licence terms are governed by the laws of England and Wales. Disputes go to the courts of England and Wales.

9. Contact

Licensing enquiries, including requests for permission to use the model in research or for collaborative work, can be directed to TerraRoxoAI via the contact options on the contact page.
