Privacy Policy
Last updated: May 19, 2026
1. Who we are
WebDevTools (webdevtools.tech) is operated by Matheus Gouveia. This policy explains how we handle personal data in line with Brazil's LGPD (Law No. 13.709/2018) and applicable privacy laws. Most tools process data only in your browser; we do not send the content you paste into tools to our servers, except when you use our test APIs or third-party services indicated in each tool.
2. Cookies and similar technologies
We use the following cookies and local storage:
Essential (no consent required)
- theme — light/dark preference
- NEXT_LOCALE — interface language
- wdt_cookie_consent — your analytics cookie choice
Optional (only with your consent)
- Google Analytics — audience and page view measurement
- Vercel Analytics — aggregated site usage statistics
- Google AdSense — ad display and personalization, when active
3. Third-party services and international transfers
If you accept optional cookies, browsing data may be processed by:
- Google LLC (Analytics and AdSense) — United States
- Vercel Inc. (hosting analytics) — United States
Legal basis: consent (LGPD Art. 7(I)). You may refuse without losing access to free site tools.
4. Google AdSense
When we show ads via Google AdSense, Google may use cookies to personalize ads, measure performance, and prevent fraud. This only happens after you consent in our cookie banner.
You can also manage personalized ads at Google Ads Settings
5. Sharing and retention
We do not sell your personal data. We share information only with the providers above when you authorize it, or when required by law. Aggregated analytics data is retained per Google and Vercel policies. Your cookie preference is stored in your browser until you change it or clear local storage.
6. Security
We apply reasonable technical and organizational measures against unauthorized access. Because tools run in the browser, avoid entering sensitive data on shared or public devices.
7. Your rights
You may at any time:
- Confirm whether we process personal data and access it
- Correct incomplete or outdated data
- Request anonymization, blocking, or deletion of unnecessary data
- Withdraw consent — use "Cookie preferences" in the footer or clear this site's storage in your browser
8. Managing consent
On your first visit we show a banner to accept or reject analytics and advertising cookies. Your choice is saved in the browser (localStorage) and the banner will not appear again until we update this policy. To change your mind, click "Cookie preferences" in the site footer.
