No. Your memories and documents are not used to train models — not by us, and not by the AI providers we use to run JustOnce.
AI models do read your content — to classify a memory, extract the people and dates in it, and answer your assistants' recall. That processing serves your account only, under provider terms that exclude training.
Two things run under your own agreements instead of ours. Your own assistants (Claude, ChatGPT, Cursor…) are governed by your agreements with those vendors; JustOnce only hands them what they ask for on your behalf. And if you add your own AI key for email forwarding, that provider handles those emails under your account with them.
Support conversations are separate from your vault: when you chat with us, the conversation and your account identifiers are processed by our support tool, and your memory content is never sent there.
