- The Platform, its design, code, algorithms, and content are owned by Pyon Labs Ltd and protected by intellectual property laws.
- You retain ownership of your trading strategies, configurations, and research data created on the Platform.
- You grant us a limited licence to process your data solely to provide the Platform services.
- AI-generated research and analysis outputs are provided for your personal use and are not guaranteed to be unique.
8. AI Features & Interaction Records
8.1 How the AI features work
- AI chat, research generation, strategy building/editing and diagnosis are powered by large language models run through our AI infrastructure providers.
- The AI assistant may use tools on your behalf: market data lookups, web search, background build jobs, and analysis modules. Web search results may include third-party content; links and content belong to their owners.
- Certain AI-initiated actions are approval-gated: they do not execute until you explicitly confirm them in the Platform. You are responsible for reviewing anything you approve.
- AI outputs can be wrong, incomplete, or out of date. They are not financial advice (see Section 9).
8.2 Interaction records
- Your AI interactions - prompts, uploaded files and images, generated outputs, tool activity, and linked results such as backtests of AI-built strategies - are recorded and stored server-side, including chat thread transcripts.
- We use these records to operate the features (conversation memory and context), for quality, safety, abuse prevention and support, to improve the Platform, and to train and evaluate Pyon's own models.
- You may request that your interaction records be excluded from model training at any time by contacting contact@pyon.io; exclusion does not affect your use of the AI features.
- Deleting your account deletes your AI interaction records. Deleting a chat thread removes it from your workspace and from the model's context.
- Details of what is collected and your rights are in our Privacy Policy.
9. Trading & Financial Disclaimer
Important Risk Warning
- The Platform is a tool for building and testing trading strategies. It does NOT provide financial advice, investment recommendations, or portfolio management services.
