No Chat Privacy Policy

1. Scope and relationship to the Terms

This policy applies to the No Chat website, web app, Android/iOS apps, Windows/macOS apps, and account, messaging, contacts, groups, attachments, Vida AI, downloads, and feedback services. Feature-specific notices or consent dialogs also apply.

The Terms of Service govern use of No Chat; this policy governs personal-information processing. They cross-reference only where necessary instead of duplicating the same rules.

2. Information we process

• Account and profile: email, verification-code records, password hash, nickname, avatar, bio, presence, birthday, time zone, interests, and profile visibility.
• Communications and social graph: contacts, blocks, group membership and roles, conversations, messages, quotes, read state, emoji, images, voice, video, files, and timestamps.
• Uploads and feedback: uploaded files and their name, size, type, thumbnail, storage path, transfer records, plus the name, email, platform, category, and content submitted through feedback.
• To protect account and service security, identify unusual logins, and troubleshoot problems, we process necessary device, network, and log information, such as system and app versions, IP addresses, and login and exception records.
• Notifications: JPush registrationId, vendor push token, aliases, and delivery, receipt, and click records.
• AI: prompts, images, files, extracted content, current documents, VidaAI context, task settings, and outputs you submit or generate. If conversation analysis is enabled, recent messages from a conversation you select are processed only after separate authorization (currently up to 100 messages).

3. Why we process information

• Provide registration, login, profiles, contacts, direct and group chat, sync, attachments, notifications, client distribution, and feedback handling.
• Record agreement versions and acceptance time, secure accounts, detect unusual logins, handle reports, and prevent fraud, spam, and abuse.
• Provide AI chat, image understanding, document processing, conversation analysis.
• Troubleshoot, maintain compatibility and reliability, and improve the product using de-identified or aggregated information where appropriate.

4. Permissions and on-device processing

• Notifications support messages and system alerts; camera supports avatars, chat capture; microphone supports voice messages.
• Photo, video, and file permissions support content you choose to send, preview, or download.
• Chat, VidaAI, and office surfaces may check locally for a clipboard image when focused. The image is uploaded or sent only after you confirm the prompt.
• You can revoke permissions in system settings. Related features may stop working, and revocation does not automatically erase previously uploaded information.

5. Sharing, processors, and disclosure

• We do not sell personal information or share chat content for advertising targeting.
• AI: after separate express consent, the server sends necessary request content to the currently configured provider, Moonshot AI (Kimi) or Volcano Engine Ark (Doubao). Declining or withdrawing does not affect non-AI features.
• Push and storage: JPush and device-vendor channels process push identifiers and notification records; cloud storage holds avatars, attachments, release packages, and feedback files.
• We may disclose or transfer information when required by law, to protect users or the public, to resolve rights claims, or as part of a corporate reorganization, subject to required notices or renewed consent.

6. Retention and security

• We retain information for the shortest period needed for the stated purpose. Accounts, messages, attachments, AI logs, and security records may have different periods based on service, audit, disputes, and legal duties.
• When the purpose ends, account deletion takes effect, or a verified deletion request is completed, we delete or anonymize unless law requires retention. Third-party retention follows the applicable provider terms and privacy policy.
• We use access controls, transport protections, permission isolation, and audit logging. No internet service is absolutely secure; we take remedial and notification steps required by law after a security incident.

7. Your choices and rights

• You can view or correct certain profile details and use available delete, recall, block, and permission controls.
• You can withdraw third-party AI data sharing under Profile > Settings. This stops new AI requests but does not undo processing already lawfully completed.
• Through website feedback, you may request access, correction, deletion, account cancellation, consent withdrawal, or an explanation. We verify identity and respond as required by law.

8. Minors

Minors should use No Chat with guardian consent and guidance. Guardians may contact us if they believe a minor's information has been handled improperly.

9. Updates and contact

We update this policy when features, providers, or processing rules change. Material changes will be announced through the website, client dialogs, in-app notices, or another reasonable channel; we will seek renewed consent where required.

Submit privacy requests, complaints, or security concerns through the website feedback entry.
