This policy explains what Zizmix (“we”, “us”) does and does not collect when you use https://zizmix.com (the “Site”).
The QR code generator, contrast checker, size calculator and capacity checker run entirely in your browser using JavaScript. The links, text, Wi-Fi names and passwords, contact details and colours you enter are processed on your device. They are not sent to our servers, and we cannot see them. We do not store them.
When you visit, our hosting provider processes standard technical data such as your IP address, browser type, device type, the pages requested and the time, in server logs used to deliver the Site, keep it secure and prevent abuse. We use Google Analytics 4 as described below.
The contact form opens your own email app with a message addressed to zizmix@gmail.com. We receive your name, email address and message only if you send that email. We use it to reply and keep it only as long as needed to handle your request.
Zizmix has applied to Google AdSense. This version of the Site retains a publisher verification meta tag and an ads.txt file, and loads Google Analytics 4. This analytics installation does not activate Google advertising scripts. Those verification files do not themselves request advertisements or set advertising cookies. If advertising is enabled later, this policy and the relevant consent controls will be updated before ad requests begin.
The links above explain Google advertising choices for reference. They do not indicate that advertising is currently active on this Site.
The Site loads fonts from Google Fonts. Your browser requests them from Google’s servers, which can receive your IP address. The QR encoder and the independent decoder used on the verification page are hosted on this Site and do not contact third parties.
The tools do not store your entries between visits, and the Site does not use local storage for tracking.
We do not sell personal information. We share data only with service providers needed to operate the Site (such as hosting and email) and where required by law.
Depending on where you live, you may have rights to access, correct, delete or restrict the use of your personal data, to object to processing, and to withdraw consent. Because we hold very little personal data, requests are usually simple. Contact zizmix@gmail.com. Residents of the EEA, UK and California may have additional rights under the GDPR, UK GDPR and CCPA/CPRA.
The Site is not directed at children under 13 and we do not knowingly collect their personal information.
We may update this policy and will change the date above when we do. Questions: zizmix@gmail.com.
Updated October 23, 2026. This site uses Google Analytics 4, including measurement ID G-B64CLTY6QN, to understand page usage. Google may receive the page address, referrer, browser/device information and interaction events. Analytics may use cookies such as _ga to distinguish visits. This integration does not deliberately send the contents of tool inputs as custom analytics events. Avoid putting personal or confidential information into page URLs.
See how Google uses information from sites that use its services and Google's cookie information. You can control cookies in your browser or use Google's Analytics opt-out browser add-on where supported. Clearing saved tool records does not itself disable analytics.
