This policy explains what information Xu Hướng Số stores when you read the website, create an account, pay and use the XHS desktop app, what it is used for, how long it is kept and how to delete it.
You do not need an account to read the blog or use the free tools. We only keep standard web server logs (such as IP address, browser and requested page) for security, abuse prevention and diagnosing issues.
We store your email, the name you enter, your password in hashed form (never the password itself) and your sign-in sessions (device, IP address, browser) to keep you signed in and protect the account. Your email is used to verify the account, to send mail about your orders (approved, needs more information, not approved) and to reset your password. If you use tools such as short links, rate alerts or bio pages, your own settings are stored with the account.
Payment is currently by bank transfer. We store the order code, amount, status, the bill image you attach to an order, your credit balance, the plans you rent and your transaction history for reconciliation. We do not collect or store bank card numbers.
The data you work with in XHS (results, your account lists, proxies and API keys) stays on your computer and is not uploaded to our servers. XHS only calls our servers to sign in, check what you may use and how many runs are left, and to submit payment orders.
We do not use advertising or cross-site tracking cookies. When you sign in, your browser keeps a session cookie that is needed to stay signed in. Your light/dark theme preference is stored locally in your browser and not sent to our servers. If we add analytics or advertising, we will update this policy before doing so.
Information is used only to run the service, keep it secure and support you. We do not sell, rent or trade your information. We use infrastructure providers (servers, email delivery, file storage) only to operate the service.
Server logs are kept only as long as needed for security and diagnostics. Account information is kept while the account exists. After you delete your account, payment history is kept under an anonymised account id, together with the bill image you sent for each order (it can show the sender's name and account number), for reconciliation and bookkeeping; uploaded images not attached to any order may remain in storage. Security and audit logs are append-only records that cannot be edited, so older sign-up and sign-in events may still contain an email, IP address, browser type and account id; they serve security and reconciliation only. Mail waiting to be sent sits in a queue for up to 24 hours, and technical error reports may leave a short-lived trace with the provider for as long as it keeps them.
You delete your account yourself in Settings, Security, on the web (or from the account menu in XHS, which opens that page). You retype your email and enter your password to confirm. When you delete, your email, name, sessions, sign-in links and personal settings (short links, bio pages, alerts, watch lists) are removed, and the file names of images you uploaded are replaced with "deleted"; remaining credit and plans are lost and not refunded. Orders, the wallet and the credit ledger are kept, together with the bill images attached to orders. You cannot delete while an order is waiting for review or on hold. Data inside the XHS app lives on your computer and is not deleted with the account.
If you have questions about this policy or want to see, correct or delete your information, contact us at [email protected]. You can also delete your account yourself as described above.
We may update this policy as the service changes. Material changes will be reflected by the date at the top of this page.
This policy is provided for transparency and is not a substitute for legal advice. If any part of it conflicts with applicable law in your jurisdiction, the applicable law governs.
