Eidolon is designed from the ground up to protect your privacy. The software runs entirely on your machine. We never see, access, store, or transmit your personal data. Full stop.
Nothing. The Eidolon application does not collect any data. There are no analytics, no telemetry, no crash reports, no usage tracking, and no phone-home mechanisms of any kind. Your conversations, observations, personal model, email credentials, and all other data remain exclusively on your local machine.
This website (eidolonai.com) may collect:
We do not use cookies for tracking. We do not use third-party analytics.
Eidolon supports optional cloud-routed LLM models (identified by a ":cloud" suffix in the model name). When you choose to use these models, your messages and context data are transmitted to the model provider's servers. This is your choice — Eidolon warns you explicitly before using a cloud model. We have no control over the model provider's data handling. For fully private operation, use local models only.
All data generated by Eidolon can be exported at any time in open formats (JSON and Apache Parquet). You own your data completely and can take it with you.
Eidolon is not directed at children under 16. We do not knowingly collect data from children.
We may update this policy to reflect changes in our practices. Significant changes will be noted on this page with an updated date.
