ChatOS ("ChatOS," "we," "us," or "our") is an AI-driven conversation-practice platform. It is operated by [Legal entity name not yet specified], with a registered address at [Business address not yet specified]. If you have questions about these Terms, see Contact information below.

You must be able to form a binding contract to use ChatOS. [Minimum age requirement not yet specified].

ChatOS does not have its own password-based account system. You sign in exclusively through Google, via Firebase Authentication. When you sign in, we receive your Google account's unique identifier and email address from Google and use them to create and identify your ChatOS account. You are responsible for maintaining the security of the Google account you use to sign in, and for all activity that occurs under your ChatOS account.

You may optionally set a display name on your account. It is not pulled from your Google profile automatically — you choose it yourself.

Signing in with Google is subject to Google's own terms of service and privacy policy, in addition to these Terms. We do not control, and are not responsible for, Google's authentication service. If Google's service is unavailable, you may be unable to sign in to ChatOS.

ChatOS lets you rehearse conversations — such as interviews, negotiations, service interactions, or other scenarios you select — with an AI counterpart that responds to what you say. You may interact by typing or by speaking (using either your browser's built-in speech recognition or a server-side transcription feature, depending on your settings). During a practice session, ChatOS may track things like elapsed time, a live "relationship" or cooperation gauge, and, after the session ends, generate a written performance report, score, and Conversation Points ("CP") that contribute to a rank and practice streak shown on your dashboard.

ChatOS is a rehearsal and practice tool. It is not a real conversation with the person, organization, or professional you may ultimately be preparing to speak with, and nothing that happens in a ChatOS session is reported to, or visible by, any third party you may be practicing for.

The character responses, transcriptions, spoken audio, scores, feedback, and reports you see in ChatOS are generated by third-party artificial intelligence models (see our Privacy Policy for which providers process this data). AI-generated content can be inaccurate, incomplete, biased, or simply wrong. Scores, feedback, and reports reflect an automated, approximate judgment of a single practice conversation — they are not a professional evaluation and do not predict how any real conversation will actually go.

ChatOS does not provide professional medical, legal, immigration, educational, employment, or financial advice, and nothing in ChatOS — including AI responses, scores, or reports — guarantees any real-world outcome (such as passing an interview, an immigration interview, an exam, or a negotiation). If you are facing a real medical, legal, immigration, educational, employment, or financial situation, consult a qualified professional. Do not rely on ChatOS as a substitute for professional advice.

When you use ChatOS, you may provide: typed messages; spoken audio (processed for transcription and then discarded — see our Privacy Policy); and free-text context about your specific situation when starting a session ("scenario context"). Together with the AI's responses, this becomes part of your conversation session record, which is stored on your account and used to generate live feedback and end-of-session reports.

You are responsible for what you submit. Do not submit information you are not comfortable having processed by our AI provider and stored as part of your account's conversation history (see our Privacy Policy for details).

You agree to use ChatOS only for its intended purpose: practicing conversations. You agree not to:

• Use ChatOS to generate, request, or attempt to extract illegal, abusive, harassing, hateful, or sexually explicit content;
• Attempt to bypass, disable, or interfere with content moderation, off-topic detection, or other safety features built into the service;
• Use ChatOS to impersonate a real, identifiable individual without their consent, or to misrepresent AI-generated output as a real conversation with a real person or organization;
• Attempt to reverse-engineer, scrape, or extract the underlying AI models, prompts, or system instructions used by ChatOS;
• Interfere with or disrupt the service, including by attempting to overload it or bypass rate/usage limits; or
• Use ChatOS in any way that violates applicable law.

Messages you submit are automatically screened by an AI moderation system. Content flagged as violating usage policies may be rejected, and repeated violations within a session may end that session automatically.

ChatOS, including its scenarios, character personas, software, and design, is owned by us or our licensors and is protected by intellectual property law. These Terms do not grant you any right to use our branding, scenario library, or character content outside of your normal use of the service.

You retain ownership of the text and context you submit to ChatOS. By submitting it, you grant us a license to store, process, and use it (including sending it to our AI provider) solely to operate and provide the service to you, as described in our Privacy Policy.

ChatOS is provided on an evolving basis. We may add, change, or remove scenarios, characters, features (including which speech-to-text or AI features are available), or limits (such as message length or recording duration) at any time, and we do not guarantee that the service will be available at all times or free of interruptions, errors, or downtime.

We may suspend or terminate your access to ChatOS if you violate these Terms, including repeated content-moderation violations or attempts to misuse the service.

You may stop using ChatOS at any time. As described in our Privacy Policy, you can currently delete individual practice sessions from your history. A self-service option to delete your entire account does not currently exist; see our Privacy Policy for how to request full account deletion.

ChatOS is provided "as is" and "as available," without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that AI-generated responses, scores, or reports will be accurate, reliable, or suitable for any particular purpose, or that the service will be uninterrupted or error-free.

[Full limitation-of-liability clause (liability caps, exclusions, and disclaimers) pending legal review — not yet finalized].

[Governing law and jurisdiction not yet specified].

We may update these Terms from time to time. If we make material changes, we will update the "Last updated" date at the top of this page. Your continued use of ChatOS after changes take effect constitutes acceptance of the updated Terms.
