Privacy Policy

The Short Version

Inputs and outputs from the free browser tools stay on your device and are not uploaded to us. The website does process limited information needed for contact messages, hosting, security, and privacy-conscious traffic and usability analytics, as explained below.

1. Browser-Tool Data We Do Not Collect

The free tools do not send us:

• Text, images, or files you process using our tools
• Passwords or keys you generate
• Converted, formatted, calculated, or generated tool output

Every tool on 3STF Tools processes data entirely within your web browser using client-side JavaScript. Avoid entering information you do not have permission to process, and review generated output before relying on it.

2. Information You Choose to Send

If you use the contact form, we process the email address, category, and message you submit so we can receive and answer it. Contact submissions are delivered to the site operator through the Telegram Bot API. Do not include passwords, payment information, private keys, or other sensitive content in a support message.

3. Analytics, Cookies, and Local Storage

We use Microsoft Clarity to understand page usage and improve usability. Clarity may process page views, clicks, scrolling, pointer movement, browser and device details, performance diagnostics, and masked page content for heatmaps and session playback. Depending on your location and consent state, Clarity may use cookies or similar identifiers. Vercel may also provide aggregated, cookie-free web analytics. Theme preference is stored locally in your browser. We do not sell this information or use it for ad targeting.

4. Service Providers

Vercel hosts the Service and may process standard request and security logs, including IP address, browser details, requested URL, and request time. Microsoft provides Clarity, and Telegram carries messages submitted through the contact form. Review the providers' policies for more information: Vercel Privacy Notice, Microsoft Privacy Statement, and Telegram Privacy Policy.

5. Children's Privacy

The Service is not directed at children under the age of 13. We do not knowingly request personal information from children. A parent or guardian should contact us if they believe a child submitted personal information.

6. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected on this page with an updated date.
