Privacy Policy

Shadouyou (“we”, “us”, or “our”) respects your privacy. This Privacy Policy describes how we handle information in connection with your access to and use of our website and tools, and the rights you may have.

Please read this Policy carefully before using the services. By using Shadouyou, you acknowledge that you understand and agree to this Policy. If you do not agree, please discontinue use immediately.

Shadouyou is designed with a local-first approach. For tools that run entirely in your browser (such as image compression, format conversion, and many PDF utilities), files you select are typically processed on your device and are not uploaded to our servers by default. In those cases, we cannot access the contents of your files.

If a feature requires a network request or server-side processing (for example third-party capabilities, or Share & Earn tools that create share links and store content on our servers), we will disclose that clearly on the relevant tool page. Files or data will not be sent until you choose to proceed.

After processing, download and retention of local output files are your responsibility. For purely local tools, we do not keep copies of your uploaded or processed files on our servers by default. For server-backed features such as Share & Earn: after you confirm publishing, links, images, documents, and similar content are stored until the link expires, you delete them, an administrator removes them, or we delete or restrict access for legal, safety, or compliance reasons. After deletion or expiry, the short link stops working and we make reasonable efforts to remove related uploaded files.

To operate, secure, and improve the services, and to comply with applicable law, we may collect limited information such as:

(1) Logs and device information: access time, page path, browser type/version, operating system, and rough network status, for troubleshooting, traffic statistics, and security;

(2) Information you submit voluntarily: for example feedback text and contact details, used only to handle your request;

(3) Cookies or similar technologies: to remember essential preferences, maintain sessions, or run aggregated analytics. You can manage cookies in your browser, but some features may be affected if disabled;

(4) Email sign-in: we store your email address and send a one-time verification code to confirm it is you. The code is used only for that sign-in and then expires; we do not keep the code itself;

(5) Share publishing data: when you use Share & Earn, we store titles, keywords, unlock mode, price, validity, shared content, and review-related information needed to create and manage share links;

(6) Share visit and unlock records: when someone opens or unlocks a share you published, we record the time, a local visitor identifier, and whether paid unlock was completed, so you can review activity in your account. We may also record the visitor’s network address for security and abuse prevention; that address is not shown to the publisher;

(7) Payment-related information: when a visitor pays to unlock content, payment is processed by Alipay or other payment providers. We store merchant order numbers, amounts, payment status, provider transaction IDs (if any), and visitor identifiers to confirm payment, credit earnings, and reconcile records. We do not collect bank card numbers or payment passwords;

(8) Withdrawal information: when you request a withdrawal, we collect the amount, your Alipay account (phone or email), and legal name for manual review and payout. Please ensure the information is accurate and matches your Alipay real-name profile.

We do not intentionally collect sensitive personal information unrelated to the services. If we expand collection in the future, we will provide notice and obtain consent where required by law.

We use information only as needed to provide and maintain the services; complete sign-in, share publishing, review, paid unlock, earnings settlement, and withdrawals; respond to feedback; perform security monitoring and abuse prevention; reconcile transactions with payment providers; meet legal obligations; and conduct aggregated or de-identified analytics.

We do not sell your personal information. We may share information only:

(1) with your consent;

(2) with service providers bound by confidentiality and data-processing obligations (such as object storage, email delivery, or payment providers);

(3) with Alipay or other payment providers as needed to complete paid unlock and payment notifications, subject to their own policies;

(4) when required by law or legal process;

(5) in connection with a corporate transaction where the successor is bound by this Policy or fresh consent is obtained.

Our site may contain links to third-party websites or services. Their privacy practices are governed by their own policies.

We implement reasonable technical and organizational measures to protect information. No method of transmission or storage is completely secure.

We retain sign-in sessions, shared content, payment orders, earnings, and withdrawal records only as long as necessary for the purposes described in this Policy, unless a longer period is required by law. Withdrawal and payout records may be kept longer for reconciliation, dispute handling, or compliance.

Subject to applicable law, you may request access, correction, deletion, or restriction of personal information we hold about you, and you may withdraw consent where processing is based on consent. Contact us via the in-site feedback channel. We may need to verify your identity before fulfilling a request. You may also manage your shares and request withdrawals in your account.

The services are intended primarily for adults. If you are a minor, use the services only with a parent or guardian’s guidance and consent. Do not publish unlawful or inappropriate content involving minors. If we learn that we collected a minor’s personal information without proper consent, we will delete it promptly.

We may update this Privacy Policy from time to time. The updated version will be posted on this page with a revised “Last updated” date. Material changes will be highlighted in a reasonable manner. Continued use after an update constitutes acceptance of the revised Policy.

If you have questions about this Privacy Policy or our data practices, please contact us through the “Feedback & Suggestions” feature on the site.
