FieldHash uses your information to provide the product, operate governed memory where enabled, and improve reliability. We do not sell your personal data. When you use AI-assisted features, the information needed to answer your request may be processed by third-party AI model providers, cloud infrastructure processors, authentication providers, storage/database services, and support tools. Enterprise deployments may also be configured to use customer-approved private or local models where appropriate. You can contact us to access, export, or delete eligible account data.
This policy applies to the FieldHash website, web app, and mobile companion app (collectively, "FieldHash"). It explains what data we collect, why we collect it, and how you can request access, export, or deletion.

FieldHash uses third-party AI model providers to power companion, research, and related AI-assisted features. When you choose to use those features, we may send the information needed to fulfill your request, including prompts, messages, relevant conversation context, and any files, documents, images, URLs, or other research inputs you explicitly submit.
This processing is used to provide the AI feature you requested, such as generating a response, analyzing submitted content, or synthesizing research outputs. The mobile app asks for your permission before sending data for AI processing.
For enterprise or qualified private deployments, FieldHash can be configured to route AI processing through customer-approved private, dedicated, or local models instead of the default hosted model providers. The exact processing path depends on the deployment agreement and technical configuration.
