JESS is privacy-first by default. Beyond the name and email used to set up your account, no data is collected — no one, including the JESS team, can view your conversations, and nothing you share is used for model training. Conversations are processed on data servers operated by ACOS Alliance. By default, your chat history is not saved: conversations are stored only in your browser and are automatically cleared within 24 hours. If you'd like to save your chats and view your history for reference later, you can opt in — that's the only way conversations are stored on our servers. You can delete a saved chat at any time, and it will be removed from our servers.
