Privacy Policy

This Privacy Policy applies to the Qudo website and its online tools, tutorials, documentation, and other related pages. This policy does not apply to third-party websites, applications, or services accessed through links on this Website. Third-party services have their own privacy policies, please review them before use.

Qudo provides online tools for text processing, format conversion, calculation, image detection, and developer assistance. Unless otherwise specified on specific tool pages, most tools process input content locally on your device using browser-side JavaScript. This means: the text you input is usually not submitted to this Website's servers; images or files you select are usually processed only in your current browser; this Website does not actively save tool input content and processing results; content not saved by you may be cleared after refreshing or closing the page. However, your browser, internet service provider, hosting provider, or third-party services used by the Website may still process regular network connection information. Please do not input or upload to tools: passwords and verification codes; bank card and payment information; ID cards, passports and other document numbers; API keys, private keys or access tokens; trade secrets; medical, financial or other highly sensitive information. If a tool needs to upload content to a server for processing in the future, we will clearly explain the processing method, purpose and retention period before submitting data on that tool page.

Cookies are small data files stored on user devices by websites. This Website may use cookies, LocalStorage or similar technologies. The technologies we use may include: 1. Necessary Cookies: used to ensure basic website functionality, security, language selection and normal page operation. These cookies usually cannot be completely disabled. 2. Functional Storage: used to remember your preferences, such as: website language; display mode; tool settings; recently used non-sensitive options. 3.

Advertising Cookies: this Website may use Google AdSense to display ads. Google and its partners may use cookies to show ads based on users' previous visits to this Website or other websites. Google uses advertising cookies to enable it and its partners to show personalized or non-personalized ads based on users' visits to this Website and other websites on the internet. You can manage Google ad personalization settings at: Google Ads Settings (https://adssettings.google.com/).

This Website may participate in the Google AdSense program to display ads through Google's advertising services. Google and its advertising partners may: use cookies or similar technologies to provide ads; show personalized ads based on users' browsing activity; show non-personalized ads based on current page content; measure ad displays and interactions; prevent invalid traffic, fraud and abuse; generate aggregate statistics and ad performance reports.

This Website may use analytics services such as Google Analytics to understand website traffic, page usage and website performance. Google Analytics may collect device, browser, pages visited, approximate location, source channel and interaction information. We use this aggregate information to improve tools and page experience, rather than actively identifying your real identity. For information on how Google Analytics processes data, please view: How Google uses data from partner sites (https://policies.google.com/technologies/partner-sites). You can also use Google's browser opt-out tool: Google Analytics Opt-out Browser Add-on (https://tools.google.com/dlpage/gaoptout).

For users from the European Economic Area, UK and Switzerland, this Website will ask whether you consent to the use of non-essential cookies, personalized advertising and related data processing through a consent management platform when required by law. You can: accept all options; reject non-essential cookies; choose personalized or non-personalized ads; manage third-party vendors; reselect at any time through "Privacy Settings" at the bottom of the page. Withdrawing consent will not affect data processing that occurred before withdrawal. If AdSense ads are shown in these regions, the Website should be configured with Google certification and support IAB TCF CMP.

We may use the collected information for: providing and maintaining website functionality; saving language and interface preferences; responding to user inquiries and feedback; diagnosing technical issues; improving website performance and user experience; statistics on website and tool usage; preventing attacks, fraud, spam and abuse; displaying and measuring ads; complying with applicable legal obligations; protecting the legitimate interests of this Website, users and third parties. We will not use content entered by users in local tool input boxes to train artificial intelligence models.

We will not disclose personal information voluntarily provided by users without reason. Information may be shared or processed in the following circumstances: providing information necessary for operation to website hosting, CDN, security protection, website analytics and advertising service providers; to prevent fraud, security incidents or technical abuse; disclosure in accordance with applicable laws, court orders or lawful requests from government authorities; to protect the rights, property and safety of this Website, users or the public; as part of relevant business assets in the event of a merger, acquisition or asset transfer of the Website. Third-party services can only process information according to their service purposes and respective privacy policies.

Tool input content usually only exists in your browser, and this Website does not actively save it. Server logs and security records may be retained for a limited period according to security, troubleshooting and legal needs. Information sent via email or contact forms will be retained for the period necessary to process inquiries; when no longer needed, we will reasonably delete or anonymize relevant information, except where legal requirements require continued retention.

We take reasonable technical and management measures to protect the website and related information, such as: using HTTPS encrypted connections; limiting information access permissions; keeping software and dependencies updated; monitoring abnormal requests and security events; minimizing collected and saved information. However, no internet transmission or electronic storage method can guarantee absolute security. Users should avoid processing highly sensitive data that cannot bear the risk of leakage through online tools.

Depending on the applicable laws of your country or region, you may have the following rights: inquire whether we process your personal information; request access to personal information we hold; request correction of inaccurate information; request deletion of relevant information; restrict or object to certain data processing; withdraw previously given consent; obtain a portable copy of data; complain to local data protection authorities. You can also through browser settings: delete or block cookies; clear LocalStorage; block third-party cookies; manage website permissions; use private browsing mode. If you wish to exercise applicable privacy rights, please contact us through the contact information at the end of this policy. We may need to take reasonable measures to verify the requester's identity.

We will not intentionally require children to provide names, contact information or other personal information. If you believe that a child has provided us with personal information without parental consent, please contact us and we will take deletion measures after reasonable verification.

This Website may contain links to third-party websites or services. We do not control the content, cookies and data processing behavior of third-party websites, nor are we responsible for third-party privacy measures. Please read their privacy policies before visiting third-party websites.

The hosting, analytics or advertising service providers used by this Website may be located in different countries or regions, so regular technical information may be processed outside your region.

We may update this Privacy Policy according to changes in website functionality, third-party services or legal requirements. The modified policy will be published on this page and the "Last Updated" date will be updated.
