Data you enter into the tools

The tools on DevKit process your input in your browser. Text, files and other data you enter are not uploaded to or stored on our servers. The What Is My IP tool sends a request to ipify.org, and the DNS Lookup tool and the optional MX check in the Email Validator send the domain name you enter to Cloudflare's public DNS-over-HTTPS service (or Google Public DNS if you select it). Those services receive your IP address as part of the request and handle it under their own privacy policies.

Local storage

We store your theme choice (light or dark) and similar interface preferences in your browser's local storage. This data never leaves your device.

Advertising and cookies

We use Google AdSense to show advertisements. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info. For more on how Google uses data, see How Google uses information from sites or apps that use its services.

Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent through a consent message before personalized ads or cookies are used, and can change their choice at any time.

Analytics

We use Google Analytics to understand how the site is used (pages visited, approximate location, device type). Google Analytics uses cookies; you can opt out with the Google Analytics opt-out browser add-on.

Server logs

Our hosting provider may record standard request logs (IP address, browser, requested page, time) for security and operations. We do not combine these logs with other data.

Children

This site is intended for a general and professional audience and is not directed at children under 13.
