1. Overview
3-Tools.com ("we", "us", "our") provides free online tools including calculators, converters, and developer utilities. This policy explains how we collect, use, and protect information when you visit our website.
2. Information We Collect
Data you enter into tools: All tool inputs are processed entirely in your browser using JavaScript. We do not send, store, or log any data you type into our tools on any server.
Automatically collected data: Like most websites, our hosting provider (Cloudflare) may collect standard web server logs including:
- IP address (anonymized)
- Browser type and operating system
- Pages visited and timestamps
- Referring website URL
This data is used solely for analytics, security, and improving our services.
3. Cookies & Advertising
We use Google AdSense to display advertisements. Google and its partners may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising at Google Ads Settings or aboutads.info.
We do not set any first-party tracking cookies ourselves.
4. Third-Party Services
We use the following third-party services:
- Cloudflare Pages — hosting and CDN
- Google AdSense — advertising
- Stripe — payment processing for optional premium features. Stripe's privacy policy is at stripe.com/privacy
Each service has its own privacy policy governing data it collects.
5. Email
If you voluntarily subscribe to our email list, we collect your email address to send you tool updates and tips. You can unsubscribe at any time via the link in every email. We use Resend for email delivery.
6. Data Retention
We do not store personal data from tool usage. Server logs are retained by Cloudflare per their standard retention policy. Email addresses are retained until you unsubscribe.
7. Children's Privacy
Our services are not directed at children under 13. We do not knowingly collect personal information from children.
8. Your Rights
Depending on your jurisdiction (e.g., GDPR, CCPA), you may have the right to access, correct, or delete personal data we hold. Since we store minimal data, contact us if you have questions.
