Privacy Policy

Last updated: April 22, 2026

This Privacy Policy explains how ZeroUtil ("we", "us", "our") handles information when you use zeroutil.com and its tools (the "Site"). Our goal is to keep the Site useful while collecting as little personal data as possible.

1. Who we are

ZeroUtil operates the Site. For any privacy-related request, contact us at [email protected]. This address is the single point of contact for access, deletion, correction, portability, and opt-out requests described below.

2. What we process locally (in your browser)

Every tool on the Site runs entirely in your web browser. Files you select, text you paste, images you upload, and any other content you feed into a tool are processed on your device. We do not upload, store, log, or transmit the content you process. This applies to every tool listed under /categories, including PDF utilities, image converters, text processors, QR code generators, and developer tools.

3. Information we do collect

Even though your tool content stays in your browser, visiting the Site involves some data collection that is standard for a modern website:

Log and device data. Your IP address, browser user agent, operating system, referring URL, and request timestamps, as automatically sent by your browser to our infrastructure provider Cloudflare.
Usage events. Aggregated pageviews, tool-used events, copy / download clicks, and search queries captured by Google Analytics and PostHog (described below). We do not attach your name, email, or account information to these events.
Error events. Uncaught JavaScript errors and unhandled promise rejections that occur on the Site, to help us fix bugs.

4. Cookies and tracking technologies

The Site uses cookies and similar technologies (localStorage, pixels) for analytics, advertising, and security. The table below names every third-party service that may set a cookie through the Site and why.

Google Analytics / Google Ads (gtag.js). Audience measurement and advertising conversion tracking. Sets cookies such as _ga and _gid. See Google's Privacy Policy.
Google AdSense. Serves the ads that support the Site. AdSense and its partners may set cookies (for example, IDE, __gads, __gpi) to measure ad impressions, prevent fraud, and select ads. See the third-party vendor disclosure in the next section.
PostHog. Product analytics for understanding which tools are used and where errors happen. PostHog is configured in memory-only persistence with Do Not Track respected, so no long-lived identifier is written to your device by PostHog itself.
Cloudflare. Our infrastructure provider sets strictly necessary cookies such as __cf_bm (bot management) and, for some visitors, cf_clearance. These are used for security and availability and are not used for advertising or tracking across sites.

5. Third-party advertising (Google AdSense disclosure)

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables Google and its partners to serve ads to you based on your visit to our Site and/or other sites on the Internet.

You may opt out of personalised advertising by visiting Google Ads Settings. You may also opt out of a third-party vendor's use of cookies for personalised advertising by visiting www.aboutads.info/choices (US / Digital Advertising Alliance) or www.youronlinechoices.eu (EU).

Google and its partners use cookies to serve ads; some of the partners used on this Site are listed in Google's ad technology providers documentation.

6. Your rights under the GDPR (EU / UK)

If you are located in the European Economic Area, the United Kingdom, or Switzerland, you have the following rights regarding personal data we process about you:

Access - ask what we hold about you.
Rectification - correct inaccurate data.
Erasure - ask us to delete your data (the "right to be forgotten").
Restriction - ask us to limit how we use your data.
Portability - receive your data in a machine-readable format.
Objection - object to processing based on legitimate interests.
Withdraw consent - where processing is based on consent, withdraw it at any time.

To exercise any of these rights, email [email protected]. You also have the right to complain to your local supervisory authority if you believe we have not handled your data properly.

7. Your rights under the CCPA / CPRA (California)

If you are a California resident, you have the right to know what personal information we collect, the right to request deletion, and the right to opt out of the "sale" or "sharing" of personal information as those terms are defined by the California Consumer Privacy Act.

We do not sell your personal information. We do allow third-party advertising partners (such as Google) to use cookies on this Site for advertising purposes, which may qualify as "sharing" under the CPRA. You can opt out at any time via the Google Ads Settings or aboutads.info/choices links above, or by emailing [email protected].

8. Children's privacy (COPPA)

The Site is not directed to children under the age of 13, and we do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact [email protected] and we will delete that information.

9. Data retention

Because tool content is processed in your browser and never reaches our servers, there is nothing for us to retain from your tool usage. Aggregated analytics data may be retained by Google and PostHog for up to 26 months per their own retention policies.

10. International transfers

The Site is delivered via Cloudflare's global network, which means the infrastructure serving your request may be located outside your country. Our advertising and analytics partners (Google, PostHog) transfer data internationally under the safeguards described in their own privacy policies and, where applicable, Standard Contractual Clauses.

11. Changes to this Privacy Policy

We may update this Privacy Policy from time to time. When we do, we will change the "Last updated" date at the top of this page. Material changes will be highlighted on the homepage or via a banner. Continued use of the Site after an update constitutes acceptance of the revised Policy.

12. Contact

For privacy questions, data requests, or complaints, email [email protected]. We aim to respond within 30 days.
