Privacy Policy

1. Introduction & Overview

Welcome to LocalDevTools ("we," "our," "us," or the "Service"), accessible at https://localdevtools.dev. We are committed to transparency, security, and protecting the privacy of our visitors and users.

This Privacy Policy describes how LocalDevTools handles data, our strict client-side operational architecture, the usage of browser storage and third-party advertising cookies, and your legal rights under regional data protection frameworks including the European Union General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA / CPRA).

2. Core Architecture: 100% Client-Side In-Browser Execution

Unlike conventional web applications that transmit user data to cloud servers for remote computation, LocalDevTools is engineered under a strict Zero Data Ingestion Architecture:

• Zero Payload Ingestion: Your source code, JSON payloads, SQL scripts, Base64 strings, regex patterns, text drafts, photos, audio files, and numeric calculation parameters are processed entirely inside your local browser memory (RAM) via HTML5 Canvas, Web Cryptography API, Web Workers, and JavaScript engines.
• No Cloud Storage: We do not operate remote databases or storage buckets that record, intercept, or inspect the data you paste, upload, format, or convert.
• Offline Operability: Once a tool page is loaded in your browser, the computational logic executes independently of network connectivity. You can disconnect your device from the internet, and the tools will continue to calculate, format, and generate results seamlessly.

3. Information We Collect (And What We Never Collect)

Because we do not require account registration or collect subscription payments, our data collection is strictly minimal:

4. Google AdSense & Third-Party Advertising Cookies

To maintain all utilities on LocalDevTools completely free for developers and visitors worldwide, we partner with third-party advertising networks, primarily Google AdSense, to serve advertisements across our website.

5. Local Storage & Client Cookies

LocalDevTools uses your web browser's native `localStorage` mechanism solely to preserve your visual and workflow preferences:

• Theme Mode (`theme`): Remembers whether you prefer Dark Mode or Light Mode across visits.
• Calibration Settings (`localdevtools_ruler_card_px`): Remembers your display calibration if you use the Screen Ruler tool.
• Zero Remote Tracking: None of this local storage information is synchronized to an external server or shared with any third party. You can clear this data at any time by clearing your browser cache.

6. Your Privacy Rights: GDPR (European Economic Area & UK)

If you reside in the European Economic Area (EEA) or the United Kingdom, you possess specific statutory rights under the General Data Protection Regulation (GDPR):

• Right of Access: You have the right to request copies of any personal communications we hold.
• Right to Rectification: You may request that we correct any inaccurate contact details.
• Right to Erasure ("Right to be Forgotten"): You may request the deletion of any email correspondence we maintain.
• Right to Restrict or Object to Processing: You have the right to object to how your personal communication is processed.

Because LocalDevTools does not store user accounts or tool calculation payloads, we hold no user data profiles. To exercise rights regarding email inquiries, contact us at [email protected].

7. California Privacy Rights (CCPA / CPRA)

Under the California Consumer Privacy Act, as amended by the California Privacy Rights Act (CPRA), California residents are entitled to specific disclosures:

• We Do Not Sell Personal Information: LocalDevTools does not sell, rent, monetize, or trade your personal information to data brokers or third parties for monetary or valuable consideration.
• Right to Know & Delete: You have the right to request disclosure of personal data collected and request its deletion.
• Non-Discrimination: We will never discriminate against you for exercising any of your CCPA/CPRA rights. All utilities remain 100% free and accessible to all users equally.

8. Children's Privacy (COPPA Compliance)

LocalDevTools is a general-audience technical and educational utility platform. We do not knowingly collect, request, or solicit personal information from children under the age of 13 in accordance with the Children's Online Privacy Protection Act (COPPA). If you believe a child under 13 has provided us with personal contact information, please notify us immediately, and we will promptly delete it.

9. Third-Party Links & Integrations

LocalDevTools may contain hyperlinks to external developer documentation, open-source specifications, RFC standards, or third-party web services. We have no control over and assume no responsibility for the privacy practices, cookie policies, or content of external websites. We encourage you to review the privacy policies of any third-party websites you visit.

10. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect technological improvements, regulatory updates, or changes in legal requirements. Any modifications will be posted directly on this page with an updated "Effective Date." Continued use of LocalDevTools following the posting of changes constitutes your acknowledgment and acceptance of the revised policy.
