Privacy Policy

1. Introduction

DevUtilKit (devutilkit.com) is a free developer tools platform that provides utility tools, documentation, and educational content for engineers, analysts, and technical teams. This Privacy Policy explains what information may be collected when you use the site, how that information is used, how long it is retained, and what rights you have in relation to your personal data. This policy applies to all users who access or use any part of DevUtilKit, including tool pages, blog pages, documentation pages, legal pages, and related support routes. By using the site, you acknowledge this policy and the data handling practices described below.

2. What Data We Collect

- Browser-side tools: DevUtilKit tools such as JSON Formatter, JWT Decoder, Base64 Converter, URL Encoder/Decoder, UUID Generator, Timestamp Converter, Cron Interpreter, Regex Tester, and CSV to JSON run entirely inside your browser using JavaScript. Input data entered into these tools is processed locally on your device and is not transmitted to DevUtilKit application servers as part of normal tool execution. You can verify this behavior yourself by opening browser developer tools and checking the Network tab while using these tools; you should not see outbound requests to devutilkit.com that include your tool input payload, transformed output, or intermediate content generated by these browser-side tools.

- SQL Runner: SQL Runner is a server-backed feature. When you execute a query in SQL Runner, the query text is sent to the DevUtilKit backend for execution against a sandboxed database environment, and the response is returned to your browser for display. DevUtilKit does not store query text or query results after the response has been sent to the client. For abuse prevention, operational stability, and security monitoring, server access logs may include metadata such as IP address, timestamp, and requested route. These access logs are retained for 30 days and are used only for reliability and abuse-prevention purposes; they do not include persisted query content from SQL Runner requests.

- Analytics: DevUtilKit uses Google Analytics to understand aggregate usage patterns and improve site reliability, navigation clarity, and content quality. Google Analytics may collect information such as page views, session duration, browser type, operating system, and anonymized IP address. This analytics data is processed by Google LLC under Google's privacy policy and data processing terms. DevUtilKit uses analytics for product and content improvement, not for storing private tool input content. Where required by applicable law, analytics behavior is subject to user consent choices provided through the site.

- Advertising: DevUtilKit uses Google AdSense to display advertisements on eligible pages. Google AdSense may set cookies and collect behavioral or contextual data in order to serve, measure, and personalize advertising content depending on user settings and legal region requirements. This advertising data is collected and processed by Google LLC. Ad personalization controls are available through Google Ad Settings at adssettings.google.com. DevUtilKit does not create user advertising profiles itself and relies on Google systems for ad delivery and related controls.

3. Cookies

Cookies are small text files stored by your browser that help websites remember session state, understand aggregate traffic, and support key functionality such as measurement and advertising. DevUtilKit uses cookies directly and through Google services. Cookies that may be present include: _ga (Google Analytics, distinguishes users, 2 years), _gid (Google Analytics, distinguishes users, 24 hours), _gat (Google Analytics, throttles request rate, 1 minute), IDE (Google DoubleClick, used by AdSense for ad targeting, 1 year), and test_cookie (Google DoubleClick, checks cookie support, session). You can control or delete cookies from your browser settings and can also use Google opt-out and ad preference tools for additional control over measurement and ad personalization behavior.

4. Third-party Services

DevUtilKit currently relies on third-party services for analytics and advertising, specifically Google Analytics and Google AdSense. Information related to these services is processed according to Google's privacy policy, available at https://policies.google.com/privacy. DevUtilKit does not sell personal data and does not share user data with additional third parties beyond the services listed in this policy for the stated operational purposes. If third-party processors are added or materially changed in the future, this policy will be updated to clearly describe those changes.

5. User Rights (GDPR)

Users located in the European Economic Area have rights under the General Data Protection Regulation, including the right to access personal data, request correction of inaccurate data, request deletion where legally applicable, restrict certain processing activities, receive data portability where relevant, and object to specific processing operations. If you want to exercise any of these rights, email support@devutilkit.com with the subject line "Privacy Request" and include enough context for us to identify the request scope and respond accurately under applicable legal timelines.

6. Data Retention

DevUtilKit does not provide user account registration and does not store browser-side tool inputs or SQL Runner query results as persistent user records. Operational server access logs, which may contain metadata such as IP address, route, and timestamp, are retained for 30 days for abuse prevention and reliability analysis. After that period, logs are removed according to routine retention practices. Analytics retention periods are governed by Google Analytics configuration and Google's own retention policies, which may vary by product settings and applicable legal requirements.

Retention boundaries are designed to support service reliability without creating unnecessary long-lived user data. Because DevUtilKit is a utility-first platform and not an account-driven application, most tool interactions do not require persistent identity records. This architecture reduces privacy risk by minimizing what can be stored in the first place. Where operational logs are necessary for security and abuse controls, they are retained for a bounded period and used for operational diagnostics rather than behavioral profiling.

7. Children's Privacy

DevUtilKit is intended for developers, technical professionals, and adult users and is not directed to children under the age of 13. We do not knowingly collect personal data from children. If you believe that a child has submitted personal data through DevUtilKit, please contact support@devutilkit.com so that we can review the situation promptly and take appropriate action, including removal of data where applicable and legally required.

8. Changes to This Policy

We may update this Privacy Policy from time to time to reflect legal requirements, product changes, infrastructure changes, or improved transparency commitments. The "Last updated" date shown at the top of this page indicates the most recent revision date. Continued use of DevUtilKit after policy updates constitutes acceptance of the revised terms to the extent permitted by law. If a change materially affects data handling expectations, we will reflect that change clearly in the policy text so users can review what has changed before continuing site usage.

Our change-management principle is technical clarity: when a policy update is tied to a product behavior change, the relevant documentation and legal pages are updated together so users can validate both behavior and disclosure in the same release cycle. This is especially important for consent behavior, ad loading controls, and backend-assisted routes where users need clear expectations before sharing sensitive snippets during debugging or analysis workflows.
