13 hentai and manga sites scanned with Blacklight for trackers, cookies, and fingerprinting. Ranked from cleanest to worst. The gap between #1 (0 trackers) and #13 (56 trackers, 186 cookies) is the widest privacy spread of any category we've tested.
Hentai and manga sites have the widest privacy gap of any adult category. Four sites in this ranking load zero trackers — you visit, you read, nobody follows you home. At the other end, Toonily loads 56 trackers and 186 cookies on a manhwa reading site. That's more surveillance than most banking platforms deploy.
Every site below was scanned with Blacklight by The Markup — the same newsroom-grade tool used to audit tracking on mainstream websites. The ranking is ordered by safety, not by content quality. If a site scans clean but has a smaller library, it's still ranked above a larger site that loads more trackers. Privacy is the point.
Zero trackers, zero cookies — the cleanest scan in the hentai category and one of the cleanest across all 1,000+ sites in our database. Massive streaming library with HD quality, a player that actually works, and functional search. Free with ads, premium removes them. If you use one hentai site, this is the one that respects your privacy while delivering the best content.
A 46.8 million visit booru archive scanning perfectly clean — 0 trackers, 0 cookies. That's remarkable for an ad-supported image board at this scale. Our live Blacklight scan confirmed the result after initial batch data suggested otherwise. Community tagging is excellent and the library is massive.
The art-focused booru with a named founder (Albert Yi) and a perfect 0/0 scan. Ad-free by design — runs on donations and Gold subscriptions instead of ad networks. At 50.6 million monthly visits, that's a principled infrastructure decision. The curated tagging system is the gold standard for image boards.
The original Rule 34 archive — if it exists, it's here. 445 million monthly visits with a perfect 0/0 Blacklight scan. That's extraordinary for any ad-supported site at this traffic volume. The interface looks like 2008 but the content library is unmatched and your visit isn't being tracked to access it.
The longest-running hentai manga archive (since 2005) with a near-perfect scan: 1 tracker, 0 cookies. 130 million monthly visits. The community tagging and bounty system (Hath currency) are unique. Single-operator dependency (Tenboro) is the biggest risk — the near-shutdown in 2019 over Dutch law proved that.
The video counterpart to Rule34.xxx, focused on SFM and Blender animations. 1 tracker, 0 cookies — a clean scan for a video streaming site. The library skews toward 3D rendered content rather than traditional anime. Search works well, upload quality varies by creator.
The largest English-language hentai manga library. 1 tracker and 4 cookies — noticeably dirtier than the animation sites and boorus above it. The tag system is exceptionally well-organized with parody, character, and artist tags. Free and ad-supported. The 4 cookies are the tradeoff for convenient access to this catalog.
Korean manhwa and adult webtoons. 1 tracker, 2 cookies — a moderate scan for a piracy-adjacent reading platform. The content is heavily Korean-focused with color webtoon format. Scanlation quality varies. Not as clean as the boorus but far from the danger zone.
A brand that died and came back under different management. Original .org shut down 2018, Fakku acquired it briefly, then the anonymous .xxx revival. 2 trackers, 2 cookies, plus adblock detection that forces you to disable your blocker — exposing you to all of it. The branding carries weight the current site hasn't earned.
Japan's largest art platform — 540 million monthly visits, 160 million works, 119 million users. Not a hentai site per se, but the R-18 section is massive. 6 trackers and 6 cookies is the cost of Pixiv's commercial ecosystem (FANBOX, BOOTH, Requests). R-18 posting blocked in US/UK since 2024. A legitimate platform with legitimate tracking.
6 trackers on a manga archive — the highest tracker count among dedicated hentai sites before you reach the outliers. The content library is huge and well-tagged, but nhentai covers similar doujinshi with 1 tracker instead of 6. Hard to recommend Hitomi when cleaner alternatives exist for the same content.
A legitimate Japanese marketplace (EISYS Inc., Tokyo, since 1996) that scanned at 25 trackers and 50 cookies — the second-worst result in our entire project. Facebook, TikTok, X, and Google remarketing pixels all present, some bypassing cookie blockers. Visa/Mastercard suspended payments in 2024-2025. The tracking is commercial-grade on a site where you're paying real money.
The worst privacy scan in our entire database: 56 trackers, 186 cookies, canvas fingerprinting active. That's 8x more trackers than the second-worst hentai site and 10x more cookies. A manhwa reading site should not be loading more surveillance than a banking platform. Our Privacy Score: 1/10 — the only site in the project to receive that rating.

Our Privacy Score tool has Blacklight data for 60+ hentai and manga sites — including ones not reviewed here.
Open Privacy Score Tool →Hanime.tv returned 0 trackers and 0 cookies in our Blacklight scan — the cleanest result of any hentai site we tested. Gelbooru, Danbooru, and Rule34.xxx also returned perfect 0/0 scans. All four are safer than nhentai (1 tracker, 4 cookies) by a measurable margin.
We scanned 13 hentai and manga sites with Blacklight. 4 had perfect 0/0 results with no fingerprinting. None contained active malware (VirusTotal clean). The real risk is privacy — trackers range from 0 (Hanime) to 56 (Toonily). Use a VPN and adblocker regardless.
Our Blacklight scan detected 1 ad tracker and 4 third-party cookies on nhentai. No session recording, no keystroke capture, VirusTotal 0/94. It's not the cleanest scan — Hanime and the boorus are cleaner — but it's not dangerous. An adblocker strips the tracker entirely.
Toonily loaded 56 third-party trackers, 186 cookies, and canvas fingerprinting in our Blacklight scan. That's the worst result across all 1,000+ sites in our database. For context, the average adult site loads about 2 trackers. Toonily loads 28x that. The fingerprinting means your device is uniquely identified even if you clear cookies.
Boorus (Gelbooru, Danbooru) are image boards with community tagging — single images, organized by tags. Manga sites (nhentai, E-Hentai, Hitomi) host sequential comics and doujinshi in reading format. Animation sites (Hanime, Rule34Video) stream video content. In our scans, boorus tend to be the cleanest category.
Pixiv loaded 6 trackers and 6 cookies — moderate tracking for a commercial art platform. It's a legitimate Japanese company (Pixiv Inc., Shibuya) with FANBOX and BOOTH monetization, so the tracking is commercial, not malicious. R-18 content posting is blocked in the US and UK since 2024, though viewing is still accessible.
