Privacy Policy

Last updated: June 2026

This Privacy Policy explains what information Dev Tools Online collects, how it is used, and your rights regarding that information.

The Short Version

Every input you enter into our developer tools — hashes, encoded strings, regex patterns, JSON data, API keys, tokens, code snippets — is processed entirely in your browser and never transmitted to our servers. We have no server infrastructure that receives your input data. When you close or reload the tab, the data is cleared from memory.

What We Do Not Collect

  • Any data you enter into our tools, including API keys, tokens, internal JSON, or proprietary code
  • Hash inputs or outputs
  • Encoded or decoded strings
  • Your name, email address, or any personally identifiable information (unless you voluntarily contact us)

What We Do Collect

We collect standard, anonymized web analytics data to understand how our site is used and to improve our tools. This includes:

  • Pages visited and approximate time spent on each page
  • Browser type and version
  • Operating system
  • Country-level geographic region (not city or street level)
  • Referral source — how you arrived at our site

This data is aggregated and cannot be used to identify you as an individual. We do not sell this data to any third party.

Cookies

We use only the cookies strictly necessary for the site to function correctly. We do not use tracking cookies, behavioral advertising cookies, or third-party cookies that profile your activity across other websites.

Google AdSense and Advertising

This site displays advertisements served by Google AdSense. As part of this service, Google and its partners may use cookies and similar technologies to serve advertisements based on your prior visits to this site and to other websites across the internet.

You can opt out of personalized advertising at any time by visiting Google's Ad Settings or by visiting aboutads.info.

Google's use of advertising cookies is governed by Google's own Privacy Policy, available at policies.google.com/privacy.

Your Rights (GDPR and CCPA)

If you are located in the European Economic Area (EEA) or the United Kingdom, you have rights under the General Data Protection Regulation (GDPR), including the right to access, correct, or delete any personal data we hold about you.

If you are a California resident, you have rights under the California Consumer Privacy Act (CCPA), including the right to know what personal information we collect and the right to request deletion.

Because we collect only anonymized, aggregated analytics data, we are generally unable to identify or retrieve individual records. For specific privacy requests, contact us at [email protected] and we will respond within 30 days.

Security Note

Because we do not store your input data server-side, there is no server-side data to breach. Your sensitive technical inputs exist only in your browser's memory and are cleared when you navigate away from the page.

Data Retention

We do not retain any data you process with our tools. Anonymized analytics data is retained for up to 26 months in aggregated form, after which it is deleted.

Third-Party Links

Our site may contain links to external websites. We are not responsible for the privacy practices of those sites and encourage you to review their privacy policies independently.

Children's Privacy

Our service is not directed to children under the age of 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this privacy policy from time to time. The date at the top of this page reflects the most recent revision. Continued use of the site after any changes constitutes your acceptance of the updated policy.
