Basics
Accounts and privacy
Chat as a guest with a visitor ID, and understand how your messages and memory are handled.
Chatting without an account
You can start a thread on Himitsu without creating an account. As a guest, you can send up to three messages before signing in to continue. Himitsu associates your thread with a visitor ID stored on your device rather than with a registered profile.
How your messages are handled
To generate replies, your chat messages and their context are processed by third-party AI providers. Raw chat messages and prompts are not intentionally sent to analytics. This is a summary, not the full picture — read the Privacy Policy for how information is actually handled, and treat it as the authoritative source.
Staying in control of your memory
What a character remembers is yours to manage. You can view, edit, and clear a thread's current memory at any time. As you keep chatting, later conversation may be summarized into memory again. See How your relationship continues for details.
