This English page is a simplified summary for reading convenience only. It is not the complete legal document. For the full and legally controlling Privacy Policy, refer to the Chinese version of this document. If this summary differs from the Chinese version, the Chinese version prevails.

This Privacy Policy is provided by Qingchuang Juejin (Qingdao) Information Technology Co., Ltd. It explains how Zinuto processes information across the website, desktop application, account service, membership service, payment/subscription/invoice/refund support, downloads, updates, and customer support. The Chinese version is the controlling legal version. Translations are provided only for reading convenience; if there is any inconsistency, the Chinese version prevails.

1. Scope

This Policy applies to the Zinuto website, desktop application, local runtime, account and membership features, Google / Apple sign-in, Apple App Store subscriptions, Paddle / Alipay website payments, downloads and updates, device-transfer assistance, feedback, and customer support.

3. Local Data Boundary

Zinuto is desktop-first, local-first training software. Training records, notes, imported market data, custom indicators, training statistics, and most workspace settings stay on your device by default and are not treated as general cloud-sync content. The cloud mainly handles account, session, membership entitlement, security audit, lightweight honor-wall sync, necessary preference or device state, minimal anonymous desktop usage statistics, and information you actively submit for support or transfer assistance.

Minimal anonymous desktop usage statistics are enabled by default. The desktop app sends a heartbeat at startup and about every 5 minutes after that. The server counts online usage, signed-in/signed-out splits, retention, and product health by hashed device installation ID, not by a real-world person. Daily per-install facts are retained for 45 days; long-term operations and trend analysis keep aggregate statistics only. The heartbeat does not collect training content, notes, imported file contents, file names, local paths, private indicators, or plaintext email.

4. How We Use Information

We use information to provide account and membership services, complete sign-in and verification-code flows, verify and sync entitlements, support payments and refunds, maintain downloads and updates, respond to support requests, prevent fraud and abuse, improve stability, and satisfy legal, compliance, audit, or dispute needs.

5. Sharing and Third-Party Services

We share information only when reasonably necessary, such as with infrastructure, storage, email, support, security, sign-in, payment, app-store, data-processing, or legal-compliance providers. Google / Apple sign-in, Apple App Store subscriptions, Paddle checkout, Alipay payments, and related billing or refund flows process necessary information under the relevant third party's rules. Zinuto does not provide your personal information to third parties for the purpose of selling it.

6. Retention and Protection

We retain cloud-side information for a reasonable necessary period based on information type, processing purpose, product function, billing audit, dispute handling, and legal requirements. We use access control, permission separation, transport protection, audit logs, and minimum necessary processing. You are also responsible for protecting your account, device, local files, backups, and network environment.

7. Your Choices and Rights

Subject to applicable law, you may start account deletion inside the app account center and contact us by email for access, correction, exceptions, privacy explanations, or other personal-information requests. Some requests may not be performed immediately or completely because of account security, order audit, dispute handling, legal obligations, or necessary service records.

8. Minors

Zinuto is intended for users who can make independent judgments about trading training and review. Minors should use the service only with guardian consent and guidance and should not submit personal information unrelated to the service.

9. Updates

We may update this Policy when product features, account/payment flows, technical implementation, service providers, or legal requirements change. The updated version will be posted on the website or related pages and takes effect from the stated date.
