Privacy Policy

1Operator Identity and Contact Information

This website, widantoo (widantoo.com, hereinafter "this site"), is operated by the widantoo team. ICP Filing No.: 粤ICP备2024247130号-1.

If you have any questions, concerns, or complaints regarding this Policy or the processing of your personal information, please contact us at: support@widantoo.com.

2What Personal Information We Collect

All image processing on this site is performed entirely in your browser locally. Your images are not collected, not uploaded, not stored, and not transmitted to our servers. We only handle the following limited information:

• Server access logs: IP address, User-Agent, access time, request URL, and referring page;
• Functional cookies / local storage: language preference, light/dark theme, conversion parameter preferences, and consent records;
• File access permission: temporarily granted by the browser when you actively select a file, used solely for that local processing session.

3Methods of Collection

Server access logs are recorded automatically by the server when you visit the site. Functional cookies / local storage are written to your device when you use the corresponding features. File access permission is requested by the browser runtime when you select a file. Images are not collected.

4Purposes of Processing

• Server access logs: used for security protection, troubleshooting, abuse prevention, and fulfillment of statutory retention obligations;
• Functional cookies / local storage: to remember your preferences and improve your experience;
• File access permission: used solely to complete the current image processing session locally on your device.

We do not use any of the above information for user profiling, personalized advertising, or sale to third parties.

5Legal Basis for Processing

Under the Personal Information Protection Law (PIPL) of mainland China, we process personal information on the bases of "necessity for the conclusion or performance of a contract to which you are a party" and "fulfillment of a statutory obligation," and do not rely on "legitimate interest." For visitors from the European Union, the corresponding bases under the GDPR are contractual necessity and legal obligation; cookies and similar technologies are processed on the basis of your consent.

6Third-Party Sharing and Commissioned Processing

We do not share your personal information. We currently have no third-party analytics, advertising, third-party login, external CDN, or external font services integrated. If any such integration becomes necessary in the future, we will update this Policy and obtain your renewed consent as required by applicable law.

7Cookies and Similar Technologies

This site uses only functional cookies and browser local storage (e.g., language, theme, and consent records). No tracking, analytics, or advertising cookies are used. You may clear them in your browser at any time without affecting core features such as image processing.

8Storage Location and Retention Period

Servers are located within mainland China. Server access logs are retained for 180 days and are deleted or anonymized upon expiry. Functional cookies / local storage are saved locally on your device until you actively clear them.

9Cross-Border Transfers

Because images are processed locally, servers are located within mainland China, and no third-party services outside China are integrated, this site does not engage in cross-border transfers of personal information.

10Data Security Measures

We implement security measures commensurate with the risks involved, including transport-layer encryption, access controls, and the principle of data minimization, to protect the limited access log information we hold.

11Your Rights and How to Exercise Them

You have the right to be informed and to make decisions, to access and copy, to correct and supplement, to delete, to data portability, to restrict or object to processing, to withdraw consent, and to lodge complaints. Because this site has no account system, "deregistration" means stopping use and clearing your local data. EU visitors additionally enjoy the corresponding rights under the GDPR. Rights may be exercised by contacting support@widantoo.com.

13Protection of Minors

This site does not actively collect personal information of minors. Personal information of individuals under 14 years of age is treated as sensitive personal information and requires guardian consent. We recommend that individuals under 18 years of age use this site with guardian supervision (consistent with the age threshold in the Terms of Service).

14Policy Update Mechanism and Effective Date

This Policy may be updated to reflect changes in features or applicable law. Updates will be published on this page with the effective date indicated (current effective date: 2026-06-04). Material changes will be communicated prominently, and we will obtain your renewed consent as required by applicable law.

15Complaints and Regulatory Complaint Channels

You may contact us first at support@widantoo.com. You also have the right to lodge a complaint with the relevant supervisory authority: in mainland China, the Cyberspace Administration; in the EU, the data protection authority (DPA) in your country of residence; in California, USA, the Office of the California Attorney General.

16Data Breach Notification and Accessibility Statement

In the event of a data security incident that may harm your rights and interests, we will take remedial action as required by law and notify you and the relevant regulatory authority in accordance with applicable regulations. This site complies with the WCAG 2.1 accessibility guidelines. If you require an alternative format or assistance, please contact us at the email address above.
