Passes Pixelscan and IPHey; open source and local." url: "https://donutbrowser.com/use-cases/privacy/" --- 1. [Home](https://donutbrowser.com/) 2. [Use Cases](https://donutbrowser.com/use-cases) 3. Anti-Fingerprint Browser For people who want their browsing data to stay theirs # Anti-Fingerprint Browser Your profiles are files on your device. Sync stays off until you turn it on, E2E Encrypted Sync locks the data with a password that never leaves your device, and the app is open source, so you can check every part of it. Download Donut Browser Read the source - Zero app telemetry - Sync off by default - Open source, AGPL-3.0 With sync off, the default, nothing leaves the device. With E2E Encrypted Sync on, the key is made from a password on the device, the password stays there, and only ciphertext goes out. App telemetry stays at zero requests. ## Donut Browser vs Tor, Brave & regular browsers How an anti-fingerprint browser compares to Tor, Brave, DuckDuckGo and incognito mode for stopping browser fingerprinting and tracking. ### Canvas / WebGL / AudioContext spoofing Donut Browser Realistic, consistent values per profile: passes Pixelscan, IPHey, CreepJS, BrowserLeaks Regular Browser Same Canvas/WebGL/Audio hash every session: trivial to fingerprint ### User-Agent & client hints spoofing Donut Browser UA, Sec-CH-UA brand/platform/arch, navigator.platform and language spoofed together Regular Browser Fixed UA; client hints leak the real OS and CPU even if you change the UA string ### WebRTC leak protection Donut Browser Per-profile WebRTC blocking and local IP spoofing: real IP never exposed Regular Browser WebRTC leaks the real IP even with a VPN enabled ### Multiple identities Donut Browser Unlimited profiles, each a distinct fingerprint + cookies + storage + optional proxy Regular Browser One identity per browser; incognito just resets cookies ### Cross-session tracking Donut Browser Impossible: every profile is a different device to the network Regular Browser Trivial via fingerprinting, even in private/incognito mode ### Per-profile VPN / proxy Donut Browser WireGuard, HTTP, HTTPS, SOCKS4, SOCKS5 bound per profile Regular Browser System-wide VPN only; one IP for everything ### Telemetry Donut Browser Zero telemetry, verifiable in the open source app Regular Browser Usage data, crash reports and browsing history commonly collected ### Source code transparency Donut Browser AGPL-3.0 on GitHub: profile manager, API and sync are auditable Regular Browser Closed source: you must trust the vendor ### Detected as a privacy browser? Donut Browser No: looks like a normal Chromium device, not flagged like Tor Regular Browser Tor is detectable and often blocked; Brave/DDG ship a known fingerprint ## Questions, answered. How do I prevent browser fingerprinting? Blocking fingerprinting APIs breaks sites and flags you as suspicious. The reliable way is to randomize the fingerprint: give each browsing session a different, realistic-looking device. Donut Browser does this automatically: every profile gets a unique Canvas, WebGL, AudioContext, font list, hardware profile, User-Agent and Client Hints, so sites see a different real device each time instead of a hardened privacy browser. How can I test my browser fingerprint? Use Pixelscan, IPHey, CreepJS, BrowserLeaks and fingerprint.com. Open each in a fresh Donut Browser profile and you will see different Canvas hashes, WebGL renderers, AudioContext values, fonts and User-Agents per profile, and no "automation/bot" flags. Profiles pass Pixelscan (including mobile), IPHey, CreepJS and BrowserLeaks, and fingerprint.com Pro does not detect them as bots. Does incognito mode stop fingerprinting? No. Incognito only clears cookies and history when you close the window. Your Canvas, WebGL, AudioContext, fonts, hardware and User-Agent are identical to your normal browser, so trackers still recognize you across incognito sessions. Donut Browser changes the fingerprint itself, which is what incognito does not do. What is the best way to stop tracking by canvas fingerprinting? Spoof the Canvas output per profile with a realistic, consistent hash rather than returning random noise (which sites detect). Donut Browser's Canvas fingerprint blocker pairs Canvas spoofing with matching WebGL, AudioContext and font lists so the whole fingerprint stays coherent and undetected. How is this different from Tor Browser? Tor Browser tries to make every user look identical, which makes Tor users very easy to identify as Tor users, and many sites block them outright. Donut Browser is a Tor browser alternative that goes the opposite way: each profile is a different, normal-looking device. You blend in instead of standing out, and you can still route any profile through a VPN or proxy if you want network-level anonymity. How is this different from Brave or DuckDuckGo? Brave and DuckDuckGo block trackers inside a single browser identity (useful), but you are still one fingerprint across everything you do. As a Brave alternative, Donut Browser lets you spin up unlimited identities, each with its own fingerprint, cookie jar, storage and optional proxy/VPN. It is a different model: separation of identities, not just blocking of trackers. What fingerprint parameters does Donut Browser spoof? Over 50 parameters: Canvas and WebGL rendering output, AudioContext (sample rate, latency, channel count), screen dimensions and color depth, hardware concurrency and device memory, User-Agent and Client Hints (brand, platform, architecture), installed fonts, timezone and language, WebRTC addresses, media devices (microphones, webcams, speakers), battery status, navigator properties (plugins, MIME types, platform) and accessibility preferences. Values are generated to be internally consistent so the fingerprint matches a plausible real device. Does a VPN stop browser fingerprinting? No. A VPN only changes your IP address. Sites can still identify you via Canvas, WebGL, AudioContext, fonts and User-Agent; your fingerprint is identical whether you use a VPN or not. Use Donut Browser's anti-fingerprint engine for the browser layer and add the built-in per-profile WireGuard or SOCKS5 proxy for the network layer. Does Donut Browser collect any data? No. Zero telemetry, no analytics, no crash reporters, no usage tracking. All profile data is stored locally. The Donut Browser app is open source under AGPL-3.0 on GitHub; you can verify this yourself. Can I use Donut Browser for everyday browsing? Yes. Create one profile per activity (personal, banking, shopping, social, work) and each one is an isolated identity with its own fingerprint and storage. Profiles persist across launches so you stay logged in. Can I run automation through anti-fingerprint profiles? Yes. Donut Browser exposes a local API so you can drive profiles with Puppeteer, Playwright or your own scripts while keeping the spoofed fingerprint and per-profile proxy. See the automation use case for the full setup. ## Your data stays on your device until you say otherwise. The app is free and open source under AGPL-3.0.
