This Privacy Policy explains how Decimal to Fraction ("we," "us," or "our"), operated from Singapore by Jie Yin, handles information when you use https://www.decimal-to-fraction.org and its decimal-to-fraction calculator, conversion guide, chart, and related features. The website is intended for users in the United States.
1. Information You Enter
The calculator is designed to process decimal values in your browser. We do not require an account, name, email address, or payment information to use the calculator. Decimal values entered into the calculator are not transmitted to or stored on our application servers.
The conversion chart is generated from fixed mathematical data. When you download the Excel chart, the file is generated in your browser and does not include personal information or your calculator input.
2. Information Collected Automatically
Our hosting and security providers may automatically process limited technical information, such as your Internet Protocol address, browser and device type, referring page, requested URL, date and time, and diagnostic or security logs. This information is used to deliver the website, maintain security, prevent abuse, and investigate technical problems.
Calculator input values and calculated fraction results are not intentionally included in analytics events or application error logs.
3. How We Use Technical Information
We process limited technical information to deliver the website, maintain security, prevent abuse, diagnose errors, and comply with applicable legal obligations. We limit this processing to information reasonably needed for those purposes. If a future feature requires consent, we will request it before activating that processing where required.
4. Analytics, Cookies, and Similar Technologies
We do not load Google Analytics, Microsoft Clarity, session replay, marketing analytics, or advertising cookies. Our hosting and security provider may use strictly necessary technologies to deliver and secure the website. We do not currently present optional consent choices because optional analytics and marketing technologies are not enabled.
5. Clipboard and Downloads
Copy features use your browser's clipboard interface only after you choose a copy control. We do not read unrelated clipboard content. Excel downloads contain the public decimal, fraction, and percentage chart and do not contain account data or calculator history.
6. Advertising
No advertising is displayed, and no advertising or targeted-marketing script is loaded. The site's code or layout may reserve locations for possible future advertising. Before activating advertising, we will update this Privacy Policy, identify the relevant providers, and add any consent or privacy controls required for the affected regions.
7. How We Share Information
We do not sell personal information, calculator inputs, or fraction results, and we do not share personal information for cross-context behavioral advertising. Limited technical information may be processed by Vercel, our current hosting, content-delivery, and security provider. We may also disclose information when reasonably necessary to comply with law, respond to valid legal requests, protect rights and safety, investigate abuse, or support a business transfer.
8. Data Retention
Because calculator inputs are processed locally and are not stored by us, we do not maintain calculator history. We do not create a separate visitor analytics database. On our current Vercel Hobby plan, runtime logs are available to us for up to one hour. Vercel and its infrastructure providers may retain separate service-generated, diagnostic, or security records for periods determined by their policies or legal obligations.
9. Your Privacy Choices and Rights
Depending on the applicable United States jurisdiction, you may have rights to request access, correction, or deletion of personal information, and to opt out of certain sales, sharing, profiling, or targeted advertising. We do not currently sell personal information, share it for cross-context behavioral advertising, or use it for targeted advertising.
We do not use personal information for solely automated decisions that produce legal or similarly significant effects. Contact us to exercise an applicable right. Because the service has no accounts and holds limited technical data, we may need enough information to verify and locate a request.
For privacy questions, applicable rights requests, or complaints, contact the Data Protection Officer listed in Section 16. We use that business contact to receive and respond to privacy inquiries and complaints.
10. Do Not Track and Global Privacy Control
The website does not currently track visitors across third-party sites or use personal information for targeted advertising. As a result, Do Not Track or Global Privacy Control signals do not change the website's behavior at this time. We will review this disclosure before enabling any technology that would make such a signal relevant.
11. International Processing
The service is operated from Singapore for users in the United States. Limited technical information may be processed in the United States, Singapore, and other countries where our infrastructure providers operate. Privacy protections and legal rights may differ between those locations.
12. Children's Privacy
The website is a general-purpose educational and utility service. It is not directed to children under 13, does not require accounts, and is not designed to knowingly collect personal information from children. If you believe a child has provided personal information, contact us so we can review and delete it where appropriate.
13. Data Security
We use reasonable technical and organizational measures intended to protect the website and the limited information processed through it. No method of transmission or storage is completely secure, so absolute security cannot be guaranteed.
14. Third-Party Links
The website may link to services or resources operated by others. Their privacy practices are governed by their own policies, and we are not responsible for their content or privacy practices.
15. Changes to This Policy
We may update this Privacy Policy when services, providers, advertising practices, or legal obligations change. The updated policy will be posted on this page with a revised effective date and will apply prospectively from that date. We will provide additional notice where required for a material change.
