Privacy Policy

Overview

Dazr is a privacy-focused browser built in Europe. This policy explains how we handle data across the Dazr browser application and the dazr.eu website. The short version: we collect as little as technically possible, and nothing leaves your device unless you explicitly trigger it.

The Dazr Browser

The Dazr browser does not collect, transmit, or store any user data on our servers. Specifically:

• No telemetry. The browser sends no analytics, usage statistics, crash reports, or diagnostic data to us or any third party.
• No accounts. There is no sign-in, no sync service, and no user accounts. Your browsing data stays on your device.
• No unsolicited network requests. The browser does not phone home. It does not ping our servers on startup, during use, or on shutdown.
• Browsing history, bookmarks, cookies, and settings are stored locally on your device and are never transmitted.
• Search queries entered in the address bar are sent to our search proxy hosted on European servers. These queries are not logged, stored, or associated with any identifier. The proxy forwards the query to upstream search providers and returns results without recording anything.
• Update checks contact our European servers to check for new versions. These requests contain only the current version number and operating system. No identifying information is sent.
• DNS queries are sent over DNS-over-HTTPS to dns0.eu (primary) and Quad9 (fallback), both European non-profit providers. We do not operate these services and have no access to query logs.
• Phishing protection uses locally cached blocklists from OpenPhish, PhishTank, and URLhaus. URLs you visit are checked against local data only and are never sent to a remote API.
• Ad and tracker blocking uses locally cached filter lists (EasyList, EasyPrivacy, uBlock). All blocking decisions are made on your device.
• Geolocation requests are routed through Beacondb, a European open-source location service. We do not process or store location data.

The dazr.eu Website

The dazr.eu website is a static site. We do not use cookies for analytics or tracking. We use a privacy-friendly analytics service to measure aggregate page views and visitor counts. This service does not use cookies, does not collect personal data, does not track individual users across pages or sessions, and does not store IP addresses. It provides only aggregate statistics (e.g., total page views per page) with no way to identify individual visitors.

All fonts use the system font stack built into your operating system. No external advertising or tracking resources are loaded.

Data We Process

When you use the search functionality on dazr.eu or through the browser's address bar, your search query is processed in memory to fetch results from upstream providers. Queries are not logged or stored. Server access logs may temporarily contain IP addresses for operational purposes (e.g., abuse prevention) but are automatically deleted within 24 hours.

Third-Party Services

The following third-party services may receive data as part of normal browser or website operation:

• dns0.eu / Quad9 - DNS resolution. Receives domain names you visit. Operated by European non-profits with their own privacy policies.
• Beacondb - Geolocation. Receives WiFi access point data when a site requests your location. European, open-source.
• Ghostery (Whotracks.me) - Filter list provider for ad/tracker blocking. Lists are downloaded and applied locally. No browsing data is sent to Ghostery.

Browser Privacy Check (dazr.eu/check)

The Browser Privacy Check page allows you to test how well your browser resists fingerprinting. This tool runs entirely in your browser using client-side JavaScript. Specifically:

• No data is transmitted. All tests execute locally in your browser. No fingerprint data, test results, or browser information is sent to our servers or any third party.
• No data is stored. Results exist only in memory while the page is open. Nothing is written to cookies, localStorage, or any persistent storage. When you close the page, everything is gone.
• Explicit consent required. Tests only run after you click the "Run Privacy Check" button. No browser APIs are probed without your action.
• APIs accessed. The check probes browser APIs commonly targeted by fingerprinting scripts, including Canvas, WebGL, AudioContext, navigator properties (hardwareConcurrency, deviceMemory, plugins, etc.), screen dimensions, performance timers, font detection, Battery API, Network Information API, storage quota, keyboard layout, media devices, permissions, Client Hints, speech synthesis, and WebGPU. These APIs are accessed read-only to check whether your browser protects them.

Data Storage

All browser data (history, bookmarks, cookies, settings, cached data) is stored locally on your device. We have no access to it. If you uninstall the browser, this data is removed with it.

Children's Privacy

We do not knowingly collect any data from anyone, including children. Since the browser collects no data, there is no age-specific concern.

Your Rights Under GDPR

Since we do not collect or store personal data, there is generally nothing to access, correct, or delete. However, if you believe we hold any data related to you (for example, from a support email), you have the right to:

• Request access to any personal data we hold
• Request correction or deletion of that data
• Object to processing
• Lodge a complaint with a supervisory authority

Contact us at hello@dazr.eu for any data-related requests.

Changes to This Policy

If we make changes to this policy, we will update the "Last updated" date at the top. For significant changes, we will note them in the browser's release notes.
