Privacy Policy
Last updated: March 13, 2026
SimpleDevTools ("we", "our", or "the site") is a free collection of browser-based developer utilities available at simpledevtools.dev. This Privacy Policy explains what information is collected when you visit the site and how it is used.
1. No Account Required
We do not require registration or login. You can use every tool on this site without providing any personal information.
2. Tool Data Stays in Your Browser
All tools on SimpleDevTools process data entirely in your browser using client-side JavaScript. Text you enter — JSON, tokens, strings, passwords — is never transmitted to our servers or any third party. We cannot see or store anything you type into a tool.
3. Cookies & Advertising
We display ads served by Google AdSense. Google may use cookies to serve ads based on your prior visits to this or other websites. These cookies are set by Google, not by SimpleDevTools.
- Google's advertising cookie allows it to serve relevant ads to you.
- You can opt out of personalised advertising by visiting google.com/settings/ads.
- You can also opt out via the Network Advertising Initiative opt-out page.
For more information on how Google uses data from sites that use its services, see How Google uses data when you use our partners' sites or apps.
4. Analytics
We use Vercel Analytics, which collects anonymised, aggregated usage data (page views, referrers, country-level geography). No personally identifiable information is collected or stored. Vercel Analytics does not use cookies.
5. Log Data
Like most web servers, Vercel's infrastructure may automatically record standard log data such as your IP address, browser type, referring URL, and pages visited. This data is used solely for operational purposes (debugging, security) and is not shared with third parties.
6. Third-Party Links
This site may contain links to external websites. We are not responsible for the privacy practices of those sites and recommend reviewing their policies before providing any personal information.
7. Children's Privacy
SimpleDevTools is not directed at children under the age of 13. We do not knowingly collect personal information from children.
8. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last updated" date above. Continued use of the site after changes constitutes acceptance of the revised policy.
