4DevTool provides browser-based developer tools and synthetic test data for QA, demos, development and automation. This policy explains what information may be processed when you use the website, API, analytics, advertising and contact channels.
Most tools are designed to run directly in your browser whenever possible. Values typed into client-side tools, generated synthetic values and copied outputs are not intentionally collected or stored by 4DevTool as user records.
Do not enter confidential production secrets, real personal data, private credentials or sensitive business information into online tools unless you have verified that the specific workflow is appropriate for your use case.
Like most websites, hosting and security infrastructure may process technical request data such as IP address, user-agent, requested URL, timestamps and error logs. This data is used for availability, abuse prevention, debugging and security.
If you contact us by email, we may receive your email address, name, message content and any information you choose to include. We use this information to respond to your request, investigate bugs, review abuse reports or handle privacy questions.
4DevTool may use local storage or cookies to remember preferences such as selected country or interface settings. Google services may also use cookies or similar technologies for analytics, consent and advertising.
We use Google Analytics to understand aggregated site usage, such as page views, device type and navigation patterns. Analytics helps prioritize improvements and identify broken experiences. Tool input content is not intentionally sent to analytics events.
4DevTool may use Google AdSense or related Google advertising services. Third-party vendors, including Google, may use cookies to serve ads based on previous visits to this site or other sites. Users can manage personalized ads in Google Ads Settings.
You can clear cookies and local storage in your browser, use browser privacy controls, opt out of personalized advertising through Google settings, or contact us about data you voluntarily sent by email.
We may update this policy as the product, advertising setup, analytics configuration or legal requirements change. The date above reflects the latest revision.
