Tool processing data: All data processed by our tools (passwords, encoded data, JSON, DNS queries, etc.) is handled entirely in your browser and is never transmitted to or stored on our servers.

3. Legal Basis for Processing (GDPR)

Under the GDPR, we process your data based on the following legal grounds:

  • Consent: When you submit the contact form, you consent to us processing your data to respond to your inquiry.
  • Legitimate interest: We have a legitimate interest in responding to user inquiries and improving our services.
  • Cookie consent: We store a single cookie to remember your cookie consent preference, which is based on your explicit consent.

4. How We Use Your Information

We use the information we collect for the following purposes:

  • Respond to your inquiries submitted through the contact form

We may share anonymized, aggregated data with advertising partners for the purpose of delivering relevant ads. This data cannot be used to identify you personally.

5. Cookies

We use cookies and similar technologies to enhance your experience, analyze site usage, and deliver relevant content. Cookies are small text files stored on your device when you visit our website.

Types of Cookies We Use

  • Essential Cookies: Required for the website to function properly. These include cookies that remember your cookie consent preference and session data. These cannot be disabled.

  • Performance Cookies: Collect information about how you use our tools, including which features are most popular and how users navigate between tools. This helps us optimize our services.
  • Advertising Cookies: Used to deliver relevant advertisements to you based on your interests. These cookies also help limit the number of times you see an advertisement and measure the effectiveness of advertising campaigns.

Third-Party Cookies

We may use third-party services that place cookies on your device, including:

  • Google Analytics: To analyze website traffic and user behavior
  • Google AdSense: To display relevant advertisements
  • Cloudflare: For security and performance optimization

These third-party services have their own privacy policies governing the data they collect through cookies.

You can control and manage cookies in several ways:

  • Cookie Consent Banner: When you first visit our site, you can accept or decline non-essential cookies through our cookie consent banner
  • Browser Settings: Most browsers allow you to block or delete cookies through their settings. Note that blocking essential cookies may affect website functionality
  • Opt-Out Links: You can opt out of Google Analytics by installing the Google Analytics Opt-Out Browser Add-on

Legal Basis for Cookies

Under GDPR, we process cookies based on:

  • Consent: For analytics, performance, and advertising cookies, we obtain your explicit consent before placing them on your device
  • Legitimate Interest: For essential cookies that are strictly necessary for the website to function

Under CCPA, advertising cookies may be considered a "sale" of personal information. You have the right to opt out of such cookies at any time.

6. Third-Party Services

Some of our tools query third-party APIs on your behalf to provide functionality:

  • DNS Checker: Queries DNS providers (Google, Cloudflare) to check DNS propagation
  • ASN Lookup: Queries Team Cymru DNS service to look up ASN information
  • Speed Test: Uses Cloudflare's speed test endpoints to measure connection speed

These queries are initiated from your browser directly to the third-party service. We do not act as an intermediary, and we do not have access to the data exchanged between your browser and these services. Each third-party service has its own privacy policy governing the data they collect.

7. Data Security

We implement appropriate technical and organizational measures to protect your data:

  • HTTPS encryption for all data transmitted between your browser and our server
