You steer the memory stack
Global memory and project memory are both opt in. You can pause updates, edit entries, or wipe a history with a single click.
Privacy is a feature, not a toggle
just4o.chat was designed for creators who need confidence as they share their ideas and routines. Memory, model control, and projects all respect consent first principles.
Transparent model choices
The chat window always runs on the exact model you select. Background memory helpers may call trusted providers like xAI, Google AI, or Anthropic, and we disclose that up front so you always know what is happening.
No surprise storage
We store only what you ask us to keep. Image generations, transcripts, and attachments follow the same rule.
Questions we hear often
We believe clarity builds trust. The answers below evolve with the product, and you can always reach out for deeper guidance.
How do memory updates work?
When a conversation yields something worth remembering, the assistant drafts a summary and shows it to you. Approve, edit, or discard it. Approved memories appear in the system prompt and can be removed later.
Where is my data processed?
Foreground replies run on the exact model you pick in the chat. Memory backends may briefly send snippets to OpenAI, xAI, Google AI, or Anthropic so we can decide whether to save something, but no human reads those snippets and everything lives in encrypted Firebase storage. We do not sell or share usage data with third parties.
Can I disable storage entirely?
Yes. Use privacy mode to run a session without writing anything to memory or project spaces. You can re enable long term memory later without losing prior data.
