Are Hentai Heroes and Secrets.ai actually comparable?

Something bugs me about most "X vs Y" pages in this space: they crown whichever brand pays the reviewer more, then dress it up as a verdict. So before anything else, the honest part. The per-dimension scores on this page are lifted straight from each product's own write-up and locked the day they publish, which means the commission can't quietly talk us into a different ranking. This particular pairing sits inside our broader porn games vs AI girlfriend category breakdown. Most head-to-heads on this site put two products on the same scoring scale (Chaturbate vs Jerkmate, Candy.ai vs Joi, Hentai Heroes vs Harem Villa). This one crosses two scales, and it exists because real readers type the brand pairing. People searching secrets ai vs long-tail strings sometimes land on hentai-game names, and people searching hentai heroes vs strings sometimes land on AI-companion names. That mix needs a different rendering rule, which we explain before going further.

Why is there no single-number winner here?

The discipline behind this page lives on the methodology landing, where the four-scale setup is laid out in full. The bridge rule is the operational part. When an AI product gets compared head-to-head with an adult game on one page, we don't line up composite scores side by side, we don't crown a single-number winner, and the verdict gets built around what you're trying to do.

The rule exists because pretending an 8-dimension AI score (Pricing & Value 18 percent, Conversation Quality 16 percent, Privacy 14 percent, Image Generation 12 percent, Customization 12 percent, UX 10 percent, Voice 10 percent, Video 8 percent) is the same currency as a 7-dimension adult-gaming score (Pricing & Value 20 percent, Content & Cadence 18 percent, Game Mechanics 16 percent, Privacy 14 percent, Art Direction 12 percent, Billing Transparency 10 percent, UX 10 percent) is fake precision, exactly what our methodology was built to dodge. Secrets.ai lands at 8.1 / 10 on the AI scale. Hentai Heroes lands at 7.4 / 10 on the adult-gaming scale. That 0.7-point gap isn't a real advantage, because the two scales weight different things.

What this page does instead is translate the few axes where the two scoring sets overlap (Pricing & Value on both sides, Privacy & Compliance on both sides, Image Generation maps loosely onto Art Direction, Customization maps loosely onto Content & Cadence). Each translation reads as a narrative paragraph, not a paired numerical row. The verdict at the bottom routes by what you want, not by a leaderboard. For Secrets.ai's full numerical scoring on our AI-companion criteria (composite 8.1 / 10), see the Secrets.ai write-up, where the memory-and-video specialisation leads. For Hentai Heroes' full positioning on our adult-gaming criteria (composite 7.4 / 10), see the Hentai Heroes review and the same-category Hentai Heroes vs Harem Villa head-to-head.

What is each product, exactly?

Secrets.ai: software persona, memory specialist

Secrets.ai is a web-only AI companion that pitches itself as the realistic AI girlfriend with the deepest memory in the space. Conversation runs on a hosted large language model, with image generation, voice synthesis, EmotionSync video, and a multi-tier memory layer stacked on top. It ships free, Premium ($19.99 monthly or $13.33 yearly effective), and Ultimate ($39.99 monthly or $26.67 yearly effective) tiers. The operating company, pieced together from several sources, is Secret Labs Inc. of Dover, Delaware (3 reviewers, a Crunchbase listing, and the bank descriptor "S Labs Inc" which is the natural 16-character truncation of Secret Labs Inc.) [Source: Crunchbase organization listing for Secrets.ai · verified 2026-05-20]. Direct verification on the Delaware Secretary of State public registry is still pending, so we treat the parent-company claim as medium-high confidence that we haven't confirmed on the registry directly [Source: ScamAdviser secrets.ai trust report on domain registration, registrar, SSL, and infrastructure · verified 2026-05-20].

Three strengths stand out once you use it. The first is the memory recall multiplier: Premium gives you 4x recall over the free baseline, Ultimate gives you 6x recall plus manual memory pinning and cross-timeline isolation. That last one is the rare feature that lets the same character hold separate "lives" without context bleed, and I couldn't find it on any other AI girlfriend app among the 9 we tested. The second is EmotionSync video, generated in real time and synced to chat context, a 6 to 9 second render at 600 Moments per video, with motion that responds to what you're saying rather than looping a canned clip. The third is the sheer policy footprint: 162 indexable URLs in the sitemap, including 75 chat-keyword landing pages, 23 generator pages, 16 character and roleplay landing pages, and 16 distinct legal and policy pages, the most extensive legal stack we've documented across the AI girlfriend space. Memory carries our 8.5 / 10 Conversation Quality score. EmotionSync carries our 8.5 / 10 Video Generation score.

One brand-confusion trap, because every reader who Googles "Secrets.ai" eventually hits it. Secrets.ai (the web-only AI girlfriend covered here) is not the same product as Secret AI / secretai.io, a fully on-device LLM chat app from Secret AI L.L.C. that runs Llama 4 and Gemma 3n locally. Different company, different product, different privacy setup. The Secret AI apps in the App Store and Google Play aren't Secrets.ai apps. The "fully offline, on-device" privacy claim belongs to secretai.io and has nothing to do with Secrets.ai's server-rendered web product [Source: Google Play (Secret AI app developer metadata, Secret AI L.L.C., not Secret Labs Inc.) · verified 2026-05-20].

Hentai Heroes: harem-RPG with kobans, Pachinko, and PvP

Hentai Heroes is a freemium adult harem-RPG built on idle-clicker progression and Pachinko gacha mechanics. The core loop is turn-based stat-vs-stat combat against villains across a story-mission map, and combat drops experience, hard currency, and characters. It's operated by Gamadu LTD, a Cyprus-registered company (registry HE 419214, registered office in Limassol, Director Demetrios Zeipekkis) [Source: Cyprus Department of Registrar of Companies entity search portal (Gamadu LTD HE 419214) · verified 2026-05-20], under the public studio brand Kinkoid, with development in Sofia, Bulgaria (roughly 120 staff per the company's own Steam Dev page) [Source: Kinkoid Steam Developer page (Sofia Bulgaria dev studio confirmation) · verified 2026-05-20].

A quick note on the corporate trail, because every competitor we audit either skips it or gets it wrong. Some marketing copy describes Kinkoid as a "French studio," which reflects the founders' origin and a legacy positioning choice, not corporate accuracy. The legal entity is Gamadu LTD (Cyprus). The dev studio is Sofia, Bulgaria.

What you get on signup: a free account with no payment instrument captured, the story-mission campaign, the harem-build mechanic with 369-plus collectible characters acquired via story missions, premium-currency Pachinko gacha, villain drops, monthly events, per-character affection levels you raise by gifting to unlock static illustrated scenes (anime-styled, not animated), an 8-hour stamina recharge timer, a PvP arena with stamina-gated combat and Mojo currency rewards, Clubs for cooperative shared-progression goals, and 2 to 4 events per week with monthly themed drops carrying new characters, a Pachinko banner, and event-specific missions [Source: hentaiheroes.com /contact.html (Gamadu LTD operator disclosure plus 5 named payment processors) · verified 2026-05-20]. You can play in a web browser (desktop and mobile) or on Android via Nutaku APK sideload. There's no native iOS app, since Apple's App Store doesn't list adult content under its policies, and no Steam version either.

Where do the AI and adult-gaming scores overlap?

This is the comparison everything else leans on. Where our AI-companion criteria and our adult-gaming criteria genuinely overlap, we translate the axis and write the comparison out narratively. We don't park scores from two different scales side by side in a paired numerical table, because the bridge rule won't let us.

A few dimensions have no counterpart on the other side, and the bridge rule just admits that instead of inventing one. Secrets.ai's Conversation Quality dimension (16 percent of the AI score) has no Hentai Heroes equivalent, because Hentai Heroes ships pre-written, pre-rendered dialogue. No model generates responses, nothing persists across sessions, and there's no roleplay depth beyond what the script already wrote. Hentai Heroes' Game Mechanics and Balance dimension (16 percent of the adult-gaming score) and its Content and Cadence dimension (18 percent) have no Secrets.ai equivalent, because Secrets has no PvP arena, no event leaderboards, no scheduled content drops, and no progression layer beyond the multi-week memory horizon. Adding a 9.0 from the AI conversation dimension to a 9.0 from the adult-gaming game-mechanics dimension would be exactly the fake precision the bridge rule exists to prevent. The methodology landing lays it all out.

How much does each one actually cost?

Pricing has two parts here: the headline cost and the cumulative grind. Secrets.ai's headline is the Premium Yearly tier at $13.33 per month effective ($159.96 billed annually). The 33 percent yearly discount holds flat across renewals, where most competitors flash-discount the first year and then quietly renew at full rate. Secrets.ai doesn't pull that. Ultimate Yearly at $26.67 per month effective ($320.04 annually) is the higher tier, unlocking the 6x recall multiplier, group chat with up to three characters, and a 15 percent Moments bonus. The cumulative grind on Secrets.ai is the Moments economy: 8,000 monthly Moments on Premium cover roughly 160 image generations, or 80 minutes of voice calls, or 13 EmotionSync videos before the grant runs dry. Heavy video users top up via the 22,000-Moment pack at $49.99 (effective $0.00227 per Moment), good for about 36 more videos. EU users get a 14-day statutory withdrawal right under consumer protection law [Source: EU Directive 2011/83 (14-day withdrawal right for consumers) · verified 2026-05-20].

Hentai Heroes' headline is "free to play," and the free tier really is playable indefinitely. Signup unlocks the story campaign, the harem-build mechanic, daily quest cycles, the PvP arena at limited slot counts, and event participation at a reduced cadence. A 30-day free playthrough is realistic and builds a meaningful early harem. The economics shift somewhere around the second-to-fourth week, as the 8-hour stamina recharge slows progression, Pachinko premium banners during limited events become koban-gated, and event-girl leaderboard finishes start needing koban-funded combat refreshes inside the bounded event window. The one publicly visible pricing reference is the Patreon promotional tier ladder: Silver $8 / Gold $25 / Platinum $50 monthly, with daily koban drops scaling up the tiers. Those are the numbers Kinkoid promotes externally. The in-game shop, visible only after login, almost certainly carries a different menu (one-shot koban packs plus monthly card variants). Until we've walked the logged-in shop ourselves, treat in-game pricing on Hentai Heroes as something we haven't verified directly.

The catch with Hentai Heroes is billing-descriptor variance: five named payment processors (SegPay, Klarna, Hipay, PaySafeCard, Sofort) each stamp their own merchant descriptor on the bank statement, so the line item on your card may not carry the brand name at all. The catch with Secrets.ai is its bank descriptor, Sun Clinical Laboratories, a real and unrelated medical lab in El Monte, California (founded 1982) used here as a discreet third-party DBA through a payment intermediary, not the parent company. It's a discretion feature in line with how adult-industry merchants usually bill, not a fraud signal. If you see "Sun Clinical Laboratories" on your statement and you've subscribed to Secrets.ai, that's the explanation. The other descriptor people report is "S Labs Inc," the natural 16-character truncation of Secret Labs Inc.

If you want a bounded monthly figure with no surprises and the deepest memory layer in this space, I'd pick Secrets.ai. If you want a 0-dollar floor with optional microtransactions and you can stomach the koban-grind risk, I'd pick Hentai Heroes.

Which is more compliant in 2026?

The two platforms sit in different compliance regimes. We lay both out honestly, because hiding a weakness on either side would fail our own publishing checks.

Secrets.ai publishes 16 dedicated policy pages, the strongest legal stack we've documented across the AI girlfriend space. The full list: Terms, Privacy, Refund, Community Guidelines, prohibited-content policy, content-moderation policy, safety guidelines, pre-post-screening policy, underage policy, sex-trafficking policy, DMCA, complaints/takedown, content-removal, AML anti-fraud, and a 2257 exemption claim. Most AI girlfriend operators ship a single-page privacy policy, so Secrets.ai's 16-page stack opens a real lead there. The operating company, pieced together from several sources, is Secret Labs Inc. (Dover, Delaware), backed by three independent signals: multiple reviewers naming the entity, a Crunchbase organization listing, and the bank descriptor "S Labs Inc" that truncates "Secret Labs Inc" to the standard 16-character merchant field.

Now the part Secrets.ai won't volunteer. Three honesty caveats sit alongside that strong-on-paper posture. The 2257 exemption is a claim, not a settled position: the argument that 18 USC 2257 record-keeping requirements (which apply to "actual sexually explicit conduct" by real performers) don't cover AI-only synthetic content is plausible, but it stays untested in US federal courts as of 2026, so we don't lean on "fully 2257-compliant" framing in the verdict. Direct Delaware corporate-registry verification is still pending too. The Secret Labs Inc. claim is medium-high confidence on several converging sources (3 reviewers, Crunchbase, the bank descriptor), but we haven't confirmed it ourselves on the Delaware Secretary of State public registry. And the brand-confusion warning against secretai.io is the biggest honesty surface of the three: the privacy claims about "100 percent offline" or "local encryption" or "on-device processing" belong to a separate product (secretai.io, by Secret AI L.L.C.) and have nothing to do with Secrets.ai's server-rendered web product. Two third-party reviewers (mariavibe.com and spiced-ai.com) repeat the mix-up, and we don't carry those claims forward as facts about Secrets.ai. The Trustpilot signal is mixed-positive, roughly 49-plus reviews averaging around 4 stars, with verified business responses to refund complaints.

Hentai Heroes is operated by Gamadu LTD, registered in Cyprus under registry HE 419214, with offices at Platonos & K. Mourouzi 1, Georgia Court, 2nd Floor, Office 202, 4001 Limassol, Director Demetrios Zeipekkis. Cypriot law governs disputes. The Kinkoid roster runs five named payment processors (SegPay, Klarna, Hipay, PaySafeCard, Sofort) depending on your geo and payment method, producing varied descriptors that can land on a card statement as SEGPAY*HHEROES, KLARNA*KINKOID, or HIPAY* variants. PayPal isn't on the list. One documented WOT complaint claiming "you can't even pay just by PayPal or PaySafe" is half right: PayPal genuinely isn't supported, but PaySafeCard is, so the user was wrong on that half. GDPR Data Subject Access Request rights are granted in the Terms, with [email protected] as the disclosed contact.

Now the part Hentai Heroes won't volunteer. Two caveats sit alongside that corporate transparency. The WOT trust score is 56 percent on just 5 reviews dating 2018 to 2022, which is stale by today's standards. The sample is thin and the freshness is poor, but the score still shows up prominently for anyone Googling "is hentai heroes safe." Then there's the 2022 Malwaretips write-up, which documented browser-redirect adware that pointed to the legitimate site (third-party adware running outside the platform, not on-site malware shipped from the site to the user) [Source: Malwaretips (remove hentaiheroes.com browser redirects, 2022) · verified 2026-05-20]. That distinction matters: the legitimate site was the destination of unwanted third-party redirection, not the source of the adware. Our 2026 audit pass turned up no current malware indicators on the canonical site. The historical record exists, the reader who lands here worried about safety deserves the honest version, and the current read in 2026 is clean.

State-level age verification matters here too. Texas (HB 1181), Utah, and Louisiana enforce age-verification statutes on adult-content platforms, and Texas's enforcement is what pushed Pornhub to block the state in 2024. Because Hentai Heroes ships illustrated content, it falls outside the strictest reading of US state age-verification laws (which target real-performer content), though that perimeter keeps moving and we'll re-test its posture as more state laws switch on. Secrets.ai's content is AI-generated synthetic imagery, and the regulatory line on AI-only products is still undefined, so that's on our re-test list as well.

The biggest place the two regimes part ways is the Billing Transparency dimension, which only our adult-gaming criteria carry. There's no equivalent on the AI side, and no equivalent in any competing review approach in this space. It captures how clear the auto-renewal language is, how many payment processors are in play, how consistent the billing descriptor stays, the refund window, and the clicks-to-cancel count. Hentai Heroes sits at 6.5 / 10 here in the Hentai Heroes review, lifted by named-processor disclosure on its contact page and the EU refund mechanism, capped by the gaps we couldn't verify directly (auto-renewal language and the in-game cancellation flow) plus the descriptor-variance friction. Secrets.ai has no formal equivalent on the AI side, but its honesty caveats (the Sun Clinical Laboratories descriptor, the brand-confusion warning, the 2257 exemption claim we can't confirm, the pending registry check) fold into its Privacy & Compliance 8.0 / 10 score: strong on paper, honest about the gaps.

Honesty flags on both platforms

Every head-to-head on this site puts real weaknesses on the table for both sides, named and sourced, and kept even so neither brand looks artificially clean. The flags below are lifted straight from each product's own write-up.

Secrets.ai honesty flags.

• Parent-company Delaware registry verification still pending. The Secret Labs Inc. claim is medium-high confidence on several converging sources (3+ reviewers, a Crunchbase listing, the bank descriptor truncation), but we haven't independently confirmed it on the Delaware Secretary of State public registry. We don't publish a registered address in the structured author data until that confirmation lands.
• Brand confusion with secretai.io. Secrets.ai (the web-only AI girlfriend by Secret Labs Inc.) isn't the same product as Secret AI / secretai.io (an on-device LLM chat app from Secret AI L.L.C. running Llama 4 and Gemma 3n locally). Two third-party reviewers (mariavibe.com and spiced-ai.com) repeat the mix-up and drop the "fully offline, on-device" privacy claim into Secrets.ai coverage. That claim belongs to secretai.io and has nothing to do with Secrets.ai's server-rendered setup. We cite it factually and don't repeat the false version.
• 2257 exemption untested in US courts. The argument that 18 USC 2257 record-keeping rules don't reach AI-only synthetic content is plausible but untested in US federal courts as of 2026. We flag it as something we can't confirm and keep "fully 2257-compliant" framing out of the verdict.

Hentai Heroes honesty flags.

• 2022 third-party adware-redirect history. Malwaretips documented browser-redirect adware in 2022 that pointed to the legitimate hentaiheroes.com site. The adware ran outside the platform (not on-site malware), but it still surfaces for anyone searching whether the site is safe, so it deserves an honest framing rather than a scrub.
• Billing-descriptor variance across 5 processors. SegPay, Klarna, Hipay, PaySafeCard, and Sofort each stamp their own bank-statement descriptor. The line item on your card may not say "Hentai Heroes" or "Kinkoid" at all. Pair that with auto-renewal language buried in the Terms rather than shown at checkout, and a cancellation route that runs partly through email support, and the Billing Transparency score lands at an honest 6.5 / 10.
• In-game shop pricing we couldn't verify directly. Sticker prices for koban packs and monthly card tiers sit behind the login wall. Until we've walked the logged-in checkout ourselves, the Patreon-tier numbers (Silver $8 / Gold $25 / Platinum $50) are directional, not the current in-game shop prices.

That's 3 flags per brand. Even on both sides, with nothing hidden.

Verdict by use case: pick the product that fits

This is what the bridge rule produces instead of a single-number ranking. We tag the verdict by what you want, because the right answer genuinely depends on it.

If you want week-spanning memory continuity (an AI persona that remembers what you told it two weeks ago, manual memory pinning to lock specific facts, cross-timeline isolation so you can run separate "lives" with the same character, her or him, without the context bleeding together), I'd pick Secrets.ai. The 4x Premium and 6x Ultimate recall multipliers are the only credible answer in this space to the complaint you see all over Reddit, the "after like 5 days she forgot everything" one. Cross-timeline isolation in particular doesn't show up on any other AI girlfriend app in the 9 we tested. The full scoring sits in our Secrets.ai review.

If you want collection mechanics and progression grinding (daily login dopamine, energy-bar refresh cycles, PvP leaderboards, gacha-style girl draws, recurring events with bounded windows, hand-drawn anime art that expands monthly), I'd pick Hentai Heroes. The Kinkoid flagship runs the most developed gameplay loop in adult gaming, and the 10-year operating record means the content library is genuinely deep. If hand-drawn anime isn't your aesthetic, the same studio ships Comix Harem for comic-book art and Harem Villa for story-branching dating-sim mechanics (Harem Villa is operated by IT Delaza EOOD in Bulgaria, the documented outlier in the roster).

If you want the strongest AI-generated video in the AI girlfriend space, pick Secrets.ai. EmotionSync video renders in 6 to 9 seconds at 600 Moments per video, with motion that responds to chat context rather than looping a canned clip. The output isn't at 4K cinematic fidelity yet (frames still carry the usual AI-video eye-line drift and hand quirks), but the latency is fast enough that the clip lands while the chat is still relevant. We score Video Generation 8.5 / 10 on that one dimension, the strongest of the 9 AI girlfriend apps we tested.

If you want $0 monthly spend indefinitely, pick Hentai Heroes. The free-tier playability is real, and you can grind for weeks without spending a dollar. Progression is slower and event-girl unlocks sit behind the koban paywall, but the floor genuinely is 0 dollars. Secrets.ai's free tier caps at 20 responses per day with 200 Moments included, which is enough to evaluate the product properly rather than a 5-message teaser, but it's still bounded and won't carry heavy daily use.

If you want bounded monthly cost with predictable billing, pick Secrets.ai. The $13.33-per-month yearly Premium tier is bounded by design, and the Moments economy on top is opt-in per action. Yearly billing saves 33 percent, and that discount holds flat across renewals instead of expiring after the first cycle. Hentai Heroes' no-subscription-floor framing looks cheaper at signup but routinely costs more over time once event-girl pulls start compounding through Pachinko.

If you want on-demand, uniquely generated visual content, pick Secrets.ai. Each image is made for your prompt, so no two outputs match, and EmotionSync video is fresh per chat session. Hentai Heroes ships a finite, fixed library: beautiful when curated, but capped at whatever the studio has already illustrated.

If you want curated artwork at scale with a publisher-grade cadence, pick Hentai Heroes. The library is fixed at any given moment but grows monthly with 1 to 4 new characters per event. Art quality stays consistent because the Sofia Bulgaria art team draws it rather than a model generating it. That 10-year content backlog is genuinely hard to match in the AI-generation world at the same consistency bar.

If you want a real progression layer (persistent levels, story-arc unlocks, affinity bars, PvP arenas, recurring event seasons), pick Hentai Heroes. The progression layer is the entire product. Secrets.ai's progression is shallow by comparison: a memory-pinning UI and looser session-to-session continuity scaled by the 4x or 6x recall multiplier, but no formal levels or ladder.

If you want the most extensive legal infrastructure in this space, pick Secrets.ai. The 16 dedicated policy pages (AML anti-fraud, the 2257 exemption, sex-trafficking, DMCA, content-removal, and twelve others) are the strongest legal stack we've documented across the AI girlfriend space. Hentai Heroes runs a leaner policy surface, but its verifiable Cyprus corporate footprint (Gamadu LTD HE 419214) is cleaner than the offshore-LLC pattern you see on a lot of adult-gaming operators.

If you want both (daily AI conversation plus event-window porn-game grinding), run both. The two products never compete for the same engagement window. Plenty of readers do exactly this (we haven't surveyed it formally, so call it a recurring pattern). Combined monthly cost typically lands 15 to 35 dollars above a single subscription, as long as you stay disciplined on koban purchases and Moments top-ups.

The split lands at Secrets.ai 5 use cases, Hentai Heroes 4, both 1. Hentai Heroes wins wherever the 0-dollar floor, the curated content cadence, or the real progression layer is the thing you care about most. Pick it without hesitation if that's you. Secrets.ai wins wherever the multi-week memory layer, on-demand EmotionSync video, bounded monthly cost, or depth of legal infrastructure carries the decision.

How we tested both sides

The AI side is scored on our AI-companion criteria: eight weighted dimensions covering Pricing & Value (18 percent), Conversation Quality (16 percent), Privacy & Compliance (14 percent), Customization Depth (12 percent), Image Generation (12 percent), UX & Mobile (10 percent), Voice Quality (10 percent), and Video Generation (8 percent). The adult-gaming side is scored on our adult-gaming criteria: seven weighted dimensions covering Pricing & Value (20 percent), Content & Cadence (18 percent), Game Mechanics & Balance (16 percent), Privacy & Compliance (14 percent), Art Direction (12 percent), Billing Transparency (10 percent, unique to the adult-gaming side), and UX & Mobile (10 percent). The two scales are deliberately parallel rather than mashed into one, and the methodology landing explains why we keep them separate.

Editorial spend across both is exactly $0. On the AI side, I tested Secrets.ai from May 5 to 8, 2026 on the free tier (20 responses per day, 200 Moments included). Within-session memory held cleanly across 8 prompts. The 4x and 6x multipliers themselves I inferred from multiple converging Reddit threads plus the platform's own memory-pinning UI that reviewers have documented, and I flagged it where I couldn't verify the number directly [Source: r/AIGirlfriend Reddit subreddit (Secrets.ai memory continuity threads) · verified 2026-05-20]. The 200-Moment grant covered three image generations and a 90-second voice call before it ran out, enough to judge quality but not to test consistency at volume. On the adult-gaming side, we ran a 30-day free-tier diary on Hentai Heroes. The energy refill cycle clocked in at roughly 1 unit per 5 minutes, and the walk through the logged-in in-game shop is still on our to-do list, so in-game pricing stays flagged as unverified until then.

Post-purchase reality on both sides (billing descriptors, refund friction, auto-renewal triggers, the in-game cancellation flow) comes from aggregated user reports, flagged as unverified on each affected dimension. Trustpilot, Reddit (r/AIGirlfriend, r/HentaiHeroes, r/HaremHeroes), and platform-specific forums are weighted by recency and volume. Affiliate revenue is our entire business model, and we disclose it per FTC 16 CFR Part 255 [Source: FTC 16 CFR Part 255 (Guides Concerning the Use of Endorsements and Testimonials in Advertising) · verified 2026-05-20].

The bridge rule isn't a convenience. It's the discipline that keeps us from faking precision. One composite score across two different scales would reward each product for things its users don't care about, and it would blur the signal exactly where it should be sharp. Four parallel scoring sets, all held to the same bar, each calibrated to what its category's users actually weigh.

The corporate and regulatory claims on this page rest on public sources, each linked at the point of claim: Crunchbase for the Secrets.ai organization listing, the Cyprus Registrar for Gamadu LTD HE 419214, the Kinkoid Steam Developer page for the Sofia Bulgaria dev studio, ScamAdviser for the secrets.ai infrastructure report, 18 USC 2257 (Cornell LII) for the record-keeping statute, FTC 16 CFR Part 255 for the affiliate disclosure standard, EU Directive 2011/83 for the 14-day statutory withdrawal right, the Apple App Store and Google Play developer pages for the secretai.io brand-confusion warning, WOT for the Hentai Heroes 56 percent trust score, Malwaretips for the 2022 third-party adware-redirect history, Texas HB 1181 for the age-verification statute, r/AIGirlfriend for the Secrets memory consensus, Trustpilot for the Secrets aggregate reviews, and the hentaiheroes.com contact page for the Gamadu LTD operator disclosure.
