Privacy Policy
Last updated: March 2026
Short version: All tools on Thezer0 Tools run entirely in your browser. We do not collect, store, or transmit any files, text, or personal data you process with our tools.
1. Information we collect
Thezer0 Tools is designed to be a privacy-first platform. We collect minimal information to keep the site running:
- Usage data: We may collect anonymised, aggregated analytics such as page views and country of origin via privacy-respecting analytics (no personally identifiable information).
- Contact form submissions: If you contact us via the contact form, we receive your name, email address, and message. This data is used solely to respond to your inquiry.
We do not collect, store, or have access to any files, images, text, or data you process using our tools.
2. How we use information
Any information we do collect is used only to:
- Respond to contact form inquiries
- Understand general traffic patterns to improve the site
- Diagnose technical issues
We do not sell, rent, or share your data with third parties for marketing purposes.
3. Client-side processing
Every tool on Thezer0 Tools — including image converters, PDF tools, text utilities, and code formatters — processes your data entirely within your web browser using JavaScript.
When you upload a file or paste text into any of our tools, that data stays on your device. It is never uploaded to our servers or any third-party server. Once you close or refresh the page, the data is gone.
4. Cookies and tracking
We use no advertising cookies or cross-site tracking. We may use a single, privacy-focused analytics cookie to count page visits in aggregate. This cookie does not identify you personally.
You can disable cookies in your browser settings at any time without affecting the functionality of any tool on this site.
5. Third-party services
Thezer0 Tools loads fonts from Google Fonts. Google may collect limited data as part of this request (such as your IP address). You can review Google's privacy policy at policies.google.com/privacy.
Some tools load open-source JavaScript libraries from trusted CDNs (such as cdnjs.cloudflare.com). These are loaded for functionality only and do not track you.
6. Children's privacy
Thezer0 Tools is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has submitted personal information to us, please contact us and we will delete it promptly.
7. Changes to this policy
We may update this Privacy Policy from time to time. We will indicate the date of the most recent update at the top of this page. Continued use of Thezer0 Tools after any changes constitutes acceptance of the updated policy.
