Security Features
Darkelf combines non-persistent browsing, network filtering, anti-fingerprinting controls, session isolation, and targeted compatibility logic. The goal is strong privacy protection without unnecessarily breaking the modern web.
Security Highlights
Ephemeral by Design
Darkelf is built around non-persistent browsing. Session data is designed to disappear with the session rather than becoming a long-lived browser profile.
Darkelf Standard Protection
A locally compiled protection ruleset combines configured upstream filter subscriptions, removes duplicate rules, excludes unsupported directives, and is parsed as a unified runtime ruleset.
Tracker & Ad Blocking
Network filtering blocks known advertising and tracking requests while refined first-party, third-party, and resource-type handling reduces unnecessary website breakage.
Canvas Fingerprint Protection
Canvas readback is blocked by default. Protected and Trusted modes provide narrowly scoped compatibility when a website genuinely requires additional canvas functionality.
First-Party Isolation
Darkelf separates first-party browsing context from third-party network activity to reduce cross-site tracking and unwanted correlation between browsing sessions.
WebRTC Protection
Shadow's privacy defaults restrict WebRTC exposure to reduce the risk of network information leaking outside the intended browsing path.
MiniAI Sentinel
MiniAI Sentinel monitors active navigations and network calls for suspicious behavior while avoiding unnecessary processing of every static image, font, and stylesheet.
Tracking-Parameter Removal
Common tracking parameters can be stripped from top-level navigation URLs, reducing passive attribution without rewriting every subresource request.
Hyperlink Ping Protection
Hyperlink ping tracking remains disabled, preventing pages from silently sending supported click-tracking beacon requests through that mechanism.
Secure Challenge Compatibility
Human-verification flows such as reCAPTCHA, hCaptcha, Cloudflare Turnstile, and Arkose/FunCaptcha receive narrowly scoped compatibility handling instead of globally disabling privacy protections.
Session-Only Trust
When a supported verification challenge requires native canvas behavior, Darkelf can grant compatibility for the current session only. The temporary grant is cleared when Darkelf closes.
Resource-Aware Filtering
ABP-style resource types are evaluated as constraints, helping prevent a rule intended for ping, image, script, or XHR traffic from being incorrectly applied to unrelated request types.
Defense in Depth
Darkelf does not rely on a single privacy mechanism. Its security model combines several independent layers so that tracking and fingerprinting are addressed at different points in the browser.
- Network layer — compiled tracker/ad rules, request-type constraints, and first/third-party awareness.
- Fingerprint layer — default canvas readback blocking with Protected and session-only Trusted compatibility modes.
- Navigation layer — tracking-parameter removal and hyperlink ping protection.
- Session layer — ephemeral browsing and temporary compatibility grants rather than permanent trust.
- Monitoring layer — MiniAI Sentinel focuses security monitoring on active navigations and network calls.
Security Without Sacrificing Compatibility
Privacy controls are most useful when websites remain usable. Darkelf therefore favors narrowly scoped exceptions and resource-aware decisions instead of disabling protection for an entire site.
- Authentication-sensitive resources receive narrowly scoped handling rather than broad filter bypasses.
- Improved compatibility with Google and Microsoft authentication flows.
- Challenge handling supports reCAPTCHA, hCaptcha, Cloudflare Turnstile, and Arkose/FunCaptcha.
- Refined cross-origin resource handling reduces broken scripts, images, logos, XHR/fetch requests, and embedded content.
- BrowserLeaks diagnostic exceptions remain tightly scoped instead of weakening normal browsing protection.
- Network-rule evaluation stops when a definitive blocking match is reached, reducing unnecessary rule scanning.
Ephemeral Privacy Model
Cookies
Designed for ephemeral session use rather than persistent cross-session identity.
Cache & Session State
Darkelf prioritizes temporary browsing state and cleanup instead of building a long-lived browsing profile.
History
The browser is designed around non-persistent browsing rather than a permanent local activity timeline.
Fingerprint Surface
Canvas protections and controlled compatibility modes reduce unnecessary fingerprint exposure while preserving functionality where required.
Network Privacy
Tracker filtering, first/third-party awareness, tracking-parameter removal, ping protection, and WebRTC controls provide multiple independent layers.
Darkelf is designed for privacy-focused, ephemeral browsing. Some websites require authentication or anti-bot features that depend on browser capabilities normally restricted for privacy. Darkelf handles supported cases with targeted, temporary compatibility rather than globally disabling its protections.
Core Security Principles
Block by Default
Privacy-sensitive capabilities such as canvas readback remain restricted unless a defined compatibility path requires them.
Scope Exceptions Narrowly
Compatibility exceptions target the resource, path, provider, or current session instead of creating unnecessary global bypasses.
Trust Should Expire
Challenge-related trust is designed to be temporary. Session compatibility state is discarded when Darkelf closes.
