We accept questions about K-line training content, chart or indicator calculations, interface problems, purchased entitlements, intellectual-property notices, security and privacy rights.

1. Information that helps us assist you

Please provide only information necessary for the issue:

1. Device model, iOS version and App version;
2. Current App language and the page, level or feature involved;
3. Reproduction steps, expected result and actual result;
4. A screenshot or screen recording with unrelated personal information removed;
5. For a purchase question, only the necessary App Store order or transaction information.

Do not send an Apple Account password, email password, verification code, payment password, full bank-card number, complete payment credentials, identity document or another person's information.

2. Training and feature reports

For a chart, candlestick, MA, VOL, MACD, score, settlement or level issue, include the level or training stage, relevant chart position, actions taken, displayed result and any reproducible steps. The App uses built-in simulated content; it is not live market data or investment advice.

For a crash, freeze, layout or display issue, include the time, repeatability, device and system details and a safe screenshot or recording where possible.

3. Purchases, billing, restore and refunds

1. The App uses a one-time, non-renewable purchase model. There is no auto-renewing subscription; a single payment unlocks the entitlement forever.
2. Restore a previously purchased entitlement with "Restore Purchases" on the App's purchase screen.
3. Request a refund or report an unrecognized charge through Apple's "Report a Problem" process or Apple Support.
4. Deleting the App, clearing local data or changing devices does not forfeit a previously purchased entitlement. Reinstall and use "Restore Purchases" to restore it.
5. Payment, refunds and transaction records are handled by Apple. We can help locate an App-side problem, but Apple decides whether a refund is approved.

4. Privacy requests

To ask about personal-information handling or request access, correction, deletion, withdrawal of consent or action concerning a child’s information, email sunny8060@foxmail.com with the subject “Privacy Rights Request — chompleek”. Describe the information involved and a reachable contact method. We may verify information reasonably necessary to prevent impersonation, but will not ask for unrelated sensitive data.

Training progress and settings stored only on your device can normally be removed by deleting the App or clearing its data. Information held by Apple or your email provider must be handled through that provider’s account, support or privacy tools.

5. Intellectual-property and security notices

For a rights notice, include your contact details, proof of the right, the specific content or location, the reason for the notice and the action requested. For a security issue, include a description, impact and reproducible steps where possible. Report these matters privately and do not access, modify, delete or disclose another person’s information.
