1. Scope
- This policy applies to www.c2345.com and SellerOS pages that reference it.
- Cookies are small browser-stored values. Local and session storage are similar browser technologies used for limited site state.
- Third-party sites reached through external links apply their own cookie policies.
2. Strictly necessary technologies
- Session and authentication cookies keep users signed in, enforce permissions, protect forms, and prevent unauthorized requests.
- Language cookies remember the user's selected public-site language.
- Disabling necessary technologies may prevent sign-in, authorization, forms, and other core functions from working.
3. Preferences and functionality
- Preference storage may remember display theme, table settings, and other choices requested by the user.
- Functionality storage is not used to sell user data or create unrelated cross-site advertising profiles.
- Users can reset these choices by clearing site data in the browser.
4. Security and server logs
- Security controls may associate a session or request with IP address, browser type, timestamps, errors, and anti-abuse signals.
- Server logs are not browser cookies but are described here for transparency because they support the same session-security boundary.
- Security records are access controlled and retained according to risk, audit, and legal needs.
5. Optional analytics and marketing
- If optional analytics is introduced, SellerOS will describe the provider, purpose, and available choices and will prefer aggregated measurement.
- If advertising or marketing cookies are introduced, users in jurisdictions requiring consent will be offered a choice before those technologies are set.
- Rejecting optional technologies will not disable strictly necessary security and service functions.
6. Third-party technologies
- User-requested sign-in, video, payment, content delivery, or platform authorization may involve a third party that sets technologies under its own policy.
- SellerOS does not claim a third-party technology is active merely because a service is supported; actual page behavior and enabled integrations control.
- External Amazon, Google, Meta, Instagram, TikTok, or other sites are governed by their own policies.
7. Retention
- Session cookies ordinarily expire on sign-out, browser close, or session timeout, depending on their function.
- Security, language, and preference values are retained only for a reasonable period needed to provide the function and are periodically reviewed.
- Related server-side logs follow the Privacy Policy and security-retention requirements.
8. Managing cookies and choices
- Browser privacy or site-data settings can view, block, or delete cookies and local storage.
- Clearing necessary cookies signs the user out and may invalidate pending forms or authorizations.
- Where SellerOS provides an optional cookie preference control, withdrawing consent applies prospectively and does not affect prior lawful processing.
9. Updates and contact
- This policy may be updated when site functions, providers, or legal requirements change.
- Material changes to optional tracking or user choices will be communicated as required.
- Questions may be sent to support@c2345.com. China contact: (+86) 0576 8403-1331. U.S. contact: +1 (909) 222-9219.
