BLOKU - Ad Blocker & Privacy

About

BLOKU — Ad Blocker & Privacy Shield

Block ads, trackers, and annoyances. BLOKU uses Chrome's built-in DeclarativeNetRequest API to filter unwanted content at the network level before it reaches your browser. Core protection runs locally on your device — your browsing stays on your machine.

Protection starts the moment you install. No account, no login, and no setup required for free ad blocking.


HOW BLOKU WORKS

BLOKU applies curated filter rules derived from widely trusted community lists (EasyList, EasyPrivacy, Fanboy Annoyances, AdGuard, and security threat feeds). Requests matching known ad servers, trackers, and malicious domains are stopped before they load, which can save bandwidth and speed up pages.

BLOKU uses Chrome's declarative filtering engine, so blocking stays efficient without running a always-on legacy background process.


WHAT BLOKU BLOCKS (FREE)

• Display ads, banner ads, and pop-ups across websites
• Third-party trackers and analytics beacons (network-level rules)
• Cookie consent banners, newsletter overlays, and similar annoyances
• Known malware, phishing, and cryptomining domains
• Cosmetic cleanup of ad containers on many sites
• Distraction presets on supported sites (hide comments, feeds, Shorts, and more)
• 28,000+ packaged network filter rules

No "acceptable ads" program. No advertiser whitelist. Ads are blocked by the same rules for everyone.


BLOKU PREMIUM (OPTIONAL UPGRADE)

• Enhanced video ad handling on YouTube and Twitch
• Privacy Shield — WebRTC leak mitigation and fingerprint hardening
• Manual distraction control — click to hide any element on any page
• Smart pattern detection for disguised promotional content
• Extended 90-day analytics and JSON export
• Unlimited per-site allowlisting (free plan: up to 5 domains)


STATISTICS & TRANSPARENCY

• Separate tracker count and estimated data saved
• 7-day blocking history (90 days with Premium)
• Filter update date and rule counts visible in Settings


CUSTOMIZATION

• Per-site allowlist — pause blocking on sites that need it (5 domains free, unlimited with Premium)
• Toggle protection layers in Settings (some advanced layers require Premium)
• Light and dark theme
• Keyboard shortcuts — open popup (Ctrl+Shift+B / Cmd+Shift+B), toggle protection (Alt+Shift+B)
• Right-click menu — whitelist site, pause/resume protection, hide distraction (Premium picker)


PRIVACY

Free features run on your device. BLOKU does not collect browsing history, page content, search queries, or activity for advertising or analytics.

Premium uses limited subscription data only — email, a device identifier, license/subscription IDs, and plan status — to activate, restore, manage, and bill your subscription through BLOKU and Polar. Payment card details are handled by Polar, not stored in the extension.
