Privacy Policy

Last updated: 2025-02-5

Introduction

Welcome to Zen! Your privacy is our priority. This Privacy Policy outlines the types of personal information we collect, how we use it, and the steps we take to protect your data when you use Zen.

We don't sell data - We don't collect data - We don't track you

1. Information We Do Not Collect

Zen is designed with privacy in mind. We do not collect, store, or share any of your personal data. Here's what that means:

1.1. No Telemetry

We do not collect any telemetry data or crash reports.

Zen has stripped out telemetry built into Mozilla Firefox. We have removed all telemetry data collection and crash reports.

1.2. No Personal Data Collection

Zen does not collect any personal information such as your IP address, browsing history, search queries, or form data.

1.3. No Third-Party Tracking

We do not allow third-party trackers or analytics tools to operate within Zen. Your browsing activity remains entirely private and is not shared with any third party. Mozilla is not considered a third party as it is the base of Zen.

1.4. External connections made at startup

Zen may make external connections at startup to check for updates and ensure the browser is up to date on plugins, addons, check for connectivity and Geolocation/push notifications services in order to comply with web standards. We, at Zen, do not collect any data from these connections, but they may be logged by third-party services or websites you visit. These connections are necessary for the proper functioning of the browser and are not used for tracking or profiling purposes. They can be disabled through the browser flags (about:config).

2. Information Stored Locally on Your Device

2.1. Browsing Data

Zen stores certain data locally on your device to enhance your browsing experience. This includes:

2.2. Settings and Preferences

Any customizations, settings, and preferences you make within Zen are stored locally on your device. We do not have access to or control over this data.

3. Sync Feature

Zen offers a "Sync" feature, which is implemented using Mozilla Firefox's Sync feature. This feature allows you to synchronize your bookmarks, history, passwords, and other data across multiple devices. For this feature to work, your data is encrypted and stored on Mozilla's servers and is treated in accordance with their Privacy Policy. We, at Zen, cannot view any of this data.

4. Add-ons and "Mods"

You can install Add-ons from addons.mozilla.org. Zen periodically checks for updates to these Add-ons. You can also install "Mods" from zen-browser.app/mods. These Mods are hosted by our services and follow the same privacy policy our website. We do not collect any data from these Mods, they are purely static content that is downloaded to your device.

5. Data Security

Although Zen does not collect your data, we are committed to protecting the information that is stored locally on your device and, if you use the Sync feature, the encrypted data stored on Mozilla's servers. We recommend that you use secure passwords, enable device encryption, and regularly update your software to ensure your data remains safe.

6. Your Control

6.1. Data Deletion

You have full control over all data stored locally on your device by Zen. You can clear your browsing data, cookies, and cache at any time using the browser's settings.

7. Our Website and Services

Zen's website and services do not use any third-party analytics, tracking, or CDN services. We do not collect any personal information from users visiting our website. The website is hosted on Cloudflare but with analytics and tracking disabled, Cloudflare may collect some analytics data from HTTP requests in order to provide security and performance improvements. However, this data is not linked to any personal information and is not used for tracking purposes.

Zen may contain links to external websites or services that are not owned or operated by us. We are not responsible for the content or privacy practices of these sites. We recommend that you review the privacy policies of these sites before providing them with any personal information.

8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or legal requirements. We will notify you of any significant changes by updating the effective date at the top of this policy. Continued use of Zen after such changes constitutes your acceptance of the new terms.

9. Other telemetry done by Mozilla Firefox

We try to disable all telemetry data collection in Zen. But, we may have missed some. Check the below links for more information.
