Privacy Policy

1. Introduction

At AI Unit Converters (accessible at aiunitconverters.com), safeguarding the privacy of our visitors is one of our utmost priorities. This Privacy Policy document delineates the types of information collected, recorded, and utilized when you browse our website and use our measurement calculation tools.

If you have questions or require additional details regarding our privacy practices, please contact us at privacy@aiunitconverters.com.

2. Client-Side Math & Calculation Privacy

AI Unit Converters is engineered with a privacy-by-architecture philosophy. All unit conversion calculations, formulas, multi-scale matrices, and interactive tools run entirely client-side in your web browser via local JavaScript and WebAssembly.

• We do not transmit, record, or store the numerical values, units, or proprietary measurements you type into our conversion tools.
• No user registration, passwords, or personal accounts are required to access any of our tools or reference tables.

3. Cookies & Browser Local Storage

Like many web applications, we utilize standard browser storage mechanisms to enhance user experience:

• Local Storage (localStorage): Used exclusively to retain your personal interface preferences—specifically, color theme (light or dark mode), preferred language, recent unit history, and haptic feedback toggles. This data resides solely on your physical device.
• Session & Necessary Cookies: Strictly necessary cookies may be set to maintain security, prevent cross-site request forgery, and retain basic consent status.

5. Analytics & CDN Telemetry

We utilize privacy-respecting aggregate analytics (such as Google Analytics 4 configured with IP anonymization and Cloudflare Web Analytics) to observe high-level operational metrics: page views, geographic distribution, device screen sizes, and browser compatibility. These diagnostics help us optimize performance and do not build invasive behavioral dossiers.

6. General Data Protection Regulation (GDPR) Notice

For users residing within the European Economic Area (EEA) and the United Kingdom, we process data in compliance with the General Data Protection Regulation (GDPR). Our legal bases for processing include legitimate interest in operating a performant web service and user consent where explicitly requested for non-essential cookies and advertising.

You hold the following statutory rights under GDPR:

• Right to Access: The right to request copies of any personal data held concerning you.
• Right to Rectification: The right to request correction of inaccurate or incomplete data.
• Right to Erasure (Right to be Forgotten): The right to request erasure of your data under certain conditions.
• Right to Restrict Processing & Object: The right to object to or restrict processing of your personal information.
• Right to Withdraw Consent: Where processing is predicated on consent, you may withdraw it at any moment.

7. California Privacy Rights (CCPA / CPRA)

Under the California Consumer Privacy Act (CCPA) as amended by the California Privacy Rights Act (CPRA), California residents are afforded specific rights concerning their personal information:

• Right to Know: Request disclosure of the categories and specific pieces of personal information collected.
• Right to Delete: Request deletion of personal data collected, subject to legal exceptions.
• Do Not Sell or Share My Personal Information: We do not sell personal data for monetary compensation. Where ad personalization is treated as "sharing" under CCPA, California residents can opt out via our Cookie Consent settings or by broadcasting the Global Privacy Control (GPC) signal.

8. Children's Privacy (COPPA)

Protecting children online is paramount. AI Unit Converters does not knowingly collect personally identifiable information from children under the age of 13. If you believe your child has submitted personal details on our site, please contact us immediately, and we will promptly purge such records.
