The volume came from ads from Meta that ran almost nonstop starting in December 2025. When big advertisers pulled back in November 1, daily installs halved. [Mobile App](https://stringers.io/en/apps/index.md) · Android · written 11-6 ZumDaten: Flirten & Chatten · M.M SPACECORE Ltd. # 15k installs push into Germany's Dating Top Grossing chart at #33: ZumDaten doesn't sell dating, it sells 'someone will always reply' **What it is** A German dating chat app. It looks like swipe-to-match with singles nearby, but some profiles are played by writers the company hires, and replies cost coins per message. **Why it's taking off** 'Host chat plus coins' makes every paying user spend tens to hundreds of euros, so a small number of installs is enough to chart in grossing. The volume comes from nearly constant Meta ads since December 2025, and daily installs halved after they stopped spending in November 1. **D** **How you could follow it** Don't copy it as is. What you can take is the chart-reading method (grossing far above free means high per-user spend), single-country Meta buying with frequent creative rotation, and per-use hooks like the spin wheel, profile viewers, and gifts. If you want a compliant version, make an AI-labeled, pay-per-message companion product, but that's a different competition. Grade D: the core relies on undisclosed hired writers posing as real people, which carries consumer protection and delisting risk in the EU. It has already been named by an Austrian consumer protection site. The same terms template is used by a dozen or more German-speaking apps, so the product has no differentiation to copy, only an old business in a new shell. Data (updated daily) · first launch 2026-01-21 · 11-07 installs 15,054 Android · Total installs worldwide Data 2026-10-29 → 2026-11-07 (10 days, 10 observations). Google's detail page only refreshes install counts every other day, so a flat day doesn't mean nobody installed. A dating app that charts only in Germany, with 15k cumulative installs, ranks among grossing charts alongside older products with millions of installs. Its user terms answer the question in clause 7: the chat partner is a 'Animateur' hired by the company, you can't meet them, and every message you send costs 10 coins. Below: how this business works, where the volume comes from, why you shouldn't copy it, and what's worth taking. ### A 20-person-upvoted one-star review In Mar 2026 6, a user named Raphael Cisternino left a review on ZumDaten's Google Play page: 'The T&Cs say: fictional fake profiles for entertainment, with hidden so-called "unlabeled paid Animateure"! Rich folks can buy expensive coins to chat with hosts, and of course you can't meet them. Another fake entertainment app, uninstalled.' 20 people marked it helpful, the most-liked review on its German store page (Google Play DE, 11-06). The same day, someone on Trustpilot wrote a longer account: they replied to a private personal ad, and the other person emailed them a zumdaten link to continue chatting on the site. Their conclusion is that the personal ad itself was a lead-generation hook planted by the operator. This is one person's account and can't be verified. The sentence they quoted is indeed in ZumDaten's own terms. The original reads: 'Zumdaten setzt zur Unterhaltung der Nutzer professionelle Animateure und Operatoren ein, die im System nicht gesondert gekennzeichnet werden … Es sind mit diesen Operatoren keine realen Treffen möglich.' (ZumDaten uses professional animateurs and operators to entertain users, who are not separately labeled in the system … Real meetings with these operators are not possible.) The website footer also says some profiles have 'no real person behind them.' Meanwhile its store page says 'ZumDaten bringt Menschen zusammen – ehrlich, nah und unkompliziert' (brings people together: honest, close, and simple), with a section titled 'Verifizierte Profile – real profiles build trust' and the tagline 'echte Singles in deiner Nähe' (real singles near you). ### What it is On the surface it's a standard dating app: swipe-based MatchGame, see who viewed your profile, people nearby, small gifts in chat, and a daily 'lucky wheel' to earn coins. Signup is free to view profiles and read messages; replying requires buying coins. Section 3 of the terms sets the prices: a message costs 10 coins, a wink 6 coins, checking out a visitor 5 coins, a gift 30 to 500 coins, and unlocking a photo 1 to 1,000 coins. The site doesn't say how much a coin costs. A similar platform, michverlieben.com, charges 155 coins for under €20, enough for about 30 messages (Watchlist Internet, 2026-07). At that rate, a single evening of back-and-forth chatting runs to tens of euros. The listed developer is M.M SPACECORE Ltd., Paphos, Cyprus, registered Oct 27, 2025, and its site calls it an agency for social media marketing, SEO and app development. But the zumdaten brand is older than the company: the earliest Trustpilot review is from June 2022. Old brand, new company. It appeared on Google Play in Jan 2026 21, and the store release date was later reset to Aug 3, reason unclear. ### 15k installs, why #33? The numbers are small: by Nov 6 it had 15,054 cumulative installs and gained 8 over 1,062 days (Google Play installs). It charts in only one country, Germany: its Dating Top Free rank fell from 38 to 48, while its Top Grossing rank rose from 37 to 33 (10-29 → 11-06). Next to it on the same Top Grossing chart: Justlo (1.83M installs), Linduu (2.85M), Herzlich (610k), Lovely (32.4M). Install counts differ by two or three orders of magnitude, yet revenue ranks sit in the same band. That can only mean each paying user spends a lot. This is the hallmark of the host-chat business: you don't need many people, just a few willing to keep chatting. Falling on Top Free and rising on Top Grossing means fewer new users, but the people paying haven't gone anywhere. The store page now shows a 4.1-star rating with over three hundred reviews, but the few readable text reviews are almost all in the vein of "all fake profiles" and "keeps crashing" (Google Play, German store, 11-06). The high rating and the negative reviews don't match, and the reason isn't visible from outside. ### Where the traffic comes from: Meta ads, and it drops when they stop. Searching "zumdaten" in the Meta Ad Library (Germany, including paused ads) turns up 26 ad sets, with two Pages running ads in turn (11-06 read): - "ZumDaten - Flirte in deiner Nähe": started running in Dec 2025 5, pushed a wave of new creatives through Feb 1, most of it running until 2026 July 20 24 when it was paused; - "ZumDaten - Flirten & Chatten": a new wave of creatives each in Aug 16, Sep 2 and Oct 3; most of the October batch was paused in Nov 1, and by Nov 6 only 2 ad sets were still running. The copy is essentially one line: "Lust auf neue Begegnungen? Entdecke Singles in deiner Nähe und starte ein Gespräch. 🥰" (Want new encounters? Discover singles near you and start a conversation.) Many creatives have two to six variants, suggesting A/B testing. The timing lines up: when the large batch was paused in Nov 1, its daily installs fell from about 200 to just over 100 (11-05 +125, 11-06 +102). The Instagram account @zumdaten has over 7,400 followers and not a single post; it exists only to run ads. No trace of it on TikTok Europe or Google ads, nor on X, Reddit, or creator content. One more timeline worth noting: in early July, the Austrian consumer site Watchlist Internet published an article titled something like "Fake bills and fake chat partners from ZumDaten, MichVerlieben and other platforms"; at the end of July the ads were paused, in Aug 3 the store release date was reset, and in Aug 16 it restarted ads under a new Page name. Whether the rebrand was prompted by the naming can't be confirmed; the timing just fits (inference). The article also describes zumdaten.com sending hundreds-of-euros "membership fee" bills to people who never registered; whether that is the same operator as this app has not been verified. ### How the money comes back The mechanics are simple. Buy male users in Germany through Meta with targeting like "singles near you"; after sign-up, someone quickly "likes" you or messages you; each reply costs 10 coins; on the other end is a writer hired by the company, usually a remote, low-paid freelancer whose job is to stretch the conversation, keep you from moving to WhatsApp, and push gifts and photo unlocks at the right moments. One paying user spending tens to hundreds of euros covers the ad cost of dozens of installs. The most efficient part of this business is that it **doesn't need real users** . The hardest part of a legitimate dating app is the cold start: no women, no men; no men, no women. Here the other side is always "someone", so a new shell can start earning on day one, and shells can be launched one after another. ### Who else does the same thing "Host chats plus coins" has run in the German-speaking market for over a decade, exposed by NDR, Stern and state consumer centers. The clause "professionelle Animateure … nicht gesondert gekennzeichnet" is almost a shared template, and it can be found word for word in the terms of iFlirts, MyDates, yoomee, Flirtduo and DateYou. | Product | Scale (Google Play, 11-06) | Compared with ZumDaten | |---|---|---| | Snoggle(Joy Media AG) | 1.23M installs, 7 days +13k, #1 Dating Top Free and #4 Top Grossing in Germany | Same model, terms describe profiles as possibly entirely fictional, with much heavier ad spend | | yoomee(mobile Trend GmbH) | 6.27M installs, 22 countries | Since 2019, an established multi-country player using the same template terms | | Justlo / Linduu / Gnoxx(Justlin Limited) | 1.84M / 2.85M | One company, multiple brands and countries; Gnoxx was on Watchlist's "coin trap" list | | Flirtduo(CYBERDREAM PTE LTD) | 26k installs, #45 Dating Top Grossing in Germany | Launched Oct 2025, the closest contemporary rival | | HERZY(Solvico Ltd) | 16k installs, 7 days +1,985,18 countries | Registered at the same Paphos address (Mosfilovounou 6) as ZumDaten's company; likely sister shells (or just shared registration-agent address) | | Tinder / Bumble / Badoo / Hinge | 100M-scale | Real-person matching plus subscriptions; a different business | On this chart, ZumDaten has nothing product-wise that sets it apart: swiping, visitors, gifts, the wheel, the terms are all the same as everyone else's. It ranks only because this model has high revenue per user and someone keeps spending on ads. ### If it were you **D: understand it, don't copy it.** This is a decade-old business in a new shell, and its core is using unlabeled hired writers posing as real people to collect payments. Copying it in the EU means running into consumer protection and unfair commercial practice law; Watchlist has already said such contracts may be unenforceable, and Google Play could pull the app at any time. Without that, what's left is an ordinary dating app shell with nothing worth copying. **Who it suits** : teams already buying ads for dating, companion or social apps who want to dissect it as a sample of "low installs, high grossing." **Who it doesn't suit** : indie devs who want a long-term product, have just one developer account, or aren't willing to stand on the edge of the law. **What's worth learning** : first, the chart-reading method. A Top Grossing rank far above the Top Free rank with tiny installs means very high per-user spend, so it's worth reading the terms to see what's actually being sold. Second, the ad rhythm: concentrated Meta spend in one country, new creatives every month or two, and traffic falls off the moment spend stops. Third, pay-per-action hooks: a daily wheel that gives coins, paid visitor views, gifts, paid photo unlocks. These work in any chat product that charges per message. **How to acquire users** : if you want a compliant version, meaning a per-message paid companion chat that **clearly tells users the other side is an AI character** , the acquisition path is the same as theirs: Meta ads in one country, with creatives saying "someone is waiting to reply" rather than "real singles near you." But be clear that this is a different product facing different competition: a crowd of AI companion apps, not the names on this chart. **When to go before the window closes** : no real deadline is recommended. ZumDaten's own run is already winding down as of the Nov 1 pause. **Where this could be wrong** : (1) through spring 2027 there has been no enforcement action against platforms like this in Germany or the EU, and ZumDaten and HERZY are still on Play and still advertising, so regulatory risk looks smaller than it seems; (2) someone has launched a clearly labeled AI pay-per-message chat that cracked the top 50 German dating Top Grossing with only tens of thousands of installs, showing that "someone always replies" demand can be sold legally, so it's worth recalculating.

What it's "running on" is a monetization model, not a product. ### 1. What the data card says, and how it holds up | items | Numbers | Source | |---|---|---| | Cumulative global installs | 13,992(10-29) → 15,054(11-06), +8 in 1,062 days, about 130/day | googleplay library app_day | | Daily install pace | 11-01 +422, 11-03 +413 (two-day combined), 11-05 +125, 11-06 +102, **clearly slowing in early November** | googleplay library | | Charts | Charts only in Germany: Dating Top Grossing 37→33 (10-29→11-06), Dating Top Free 38→48 | googleplay library chart_rank | | Top Grossing vs. Top Free | Top Grossing holding steady or rising while Top Free falls = fewer new users, but paying users haven't dropped off | Same as above | | Launched | Kuri verdict **2026-01-21** (earliest review); the 2026-08-03 on the data card is the date after the store listing was reset | googleplay library app.released | | Rating / reviews | The store doesn't show a rating, and Kuri has no review sample | Data card | | iOS | The official site says "iOS coming soon", and the App Store DE store can't find it | itunes search API(2026-11-06) | In the same German Dating Top Grossing chart at #26–36: Justlo (1.83M installs), Linduu (2.85M), Lovely (32.4M), Herzlich (610k). ZumDaten got into this tier with only 15k installs, which suggests **very high spend per paying user** . That fits the pattern below. ### 2. What it actually is: the AGB says "hosts" - Footer of zumdaten.de: "ZumDaten betreibt einen teilweise moderierten Chat-Dienst für Erwachsene … moderierte Profile, hinter denen keine realen Personen stehen und mit denen persönliche Treffen nicht möglich sind" (runs a partly moderated adult chat service; the profiles are moderated, no real people stand behind them, and in-person meetings are not possible). Source: [zumdaten.de/impressum](https://zumdaten.de/impressum) - AGB clause 7: "Zumdaten uses professional animators and operators to entertain users, who are not marked separately in the system … No real meetings are possible with these operators." Source: [zumdaten.de/agb](https://zumdaten.de/agb) - Pricing: free sign-up only lets you view profiles and read messages. **Sending a message costs 10 coins** , a wink 6 coins, seeing visitors 5 coins, gifts 30–500 coins, unlocking photos 1–1000 coins. Source: same AGB, clause 3. The coin price isn't public; a comparable platform, michverlieben.com, sells 155 coins for about €20, roughly enough for 30 messages (Watchlist Internet, 2026-07). - Store copy hooks like "Wheel of Fortune daily spin gives coins", "send small gifts" and "see who viewed you" are standard for this kind of platform. - Operator: **M.M SPACECORE Ltd.** , Paphos, Cyprus, registration no. HE482679,2025-10-27 incorporated; its site mm-spacecore.com calls itself a social media marketing / SEO / email marketing / app development agency.

It moved to the new Cypriot company at the end of 2025 and was then made into an Android app. Source: [www.trustpilot.com/review/zumdaten.de](https://www.trustpilot.com/review/zumdaten.de) ### 3. Competitors: many players in the same business, mostly veterans of this model "Host chat + coins" has a history of at least a dozen years in German-speaking markets (covered by NDR/funk undercover reports, Verbraucherzentrale, Watchlist Internet, e-commerce-kanzlei). The AGB line "professionelle Animateure und Operatoren … nicht gesondert gekennzeichnet" is almost **the same template** , appearing word for word on iFlirts (Appspartner B.V.), MyDates (Boranu), yoomee, iCatched, Flirtduo and DateYou. | Competitors | Platform | Launched | Scale (googleplay library, 11-06) | How it differs from ZumDaten | |---|---|---|---|---| | Snoggle(Joy Media AG) | Android/iOS | Not verified | 1.23M installs, 7 days +13k, #1 Dating Top Free and #4 Top Grossing in Germany | Same model (AGB says "moderated profiles … may be entirely fictional"), but two orders of magnitude larger, Germany-only, and far heavier advertising | | yoomee(mobile Trend GmbH) | Android/iOS | 2019 | 6.27M installs, 22 countries | Same template AGB (quoted by zu-zweit.de), an older brand spread across many countries | | Justlo / Linduu / Gnoxx(Justlin Limited) | Android | From ¥2020 | Justlo 1.84M, Linduu 2.85M | Same category; gnoxx.de is on Watchlist's "Coin trap" list; one company runs many brands in many countries (Gnoxx also has a French version) | | Flirtduo(CYBERDREAM PTE LTD) | Android | 2025-10 | 26k installs, #45 Dating Top Grossing in Germany | **The closest contemporary rival** : the same AGB sentence, with similarly small install counts charting in Top Grossing | | HERZY(Solvico Ltd) | Android | 2026-08/09 | 16k installs, 7 days +1,985,18 countries | **Likely the same group** : Solvico Ltd is registered at the same Paphos address (Mosfilovounou 6, Peristerona 8810) and likewise calls itself a "marketing agency". One is a multi-country version | | Viluu, Herzlich, Bettdeckengeflüster, POPCORN, iSingles and others | Android | 2019–2025 | 60k–1.27M | Whether the operators are behind each of these similar "small installs, high grossing" products in the top 50 German Dating Top Grossing has not been verified one by one | | Tinder / Bumble / Hinge / Badoo | All platforms | 2010–2017 | 100M-scale | Real two-sided marketplaces on subscription; ZumDaten doesn't compete with them on real matches. It sells "someone will definitely reply to you" | Conclusion: **no product differentiation** . Competitors exist in batches, and the same address already hosts sister shells (HERZY). ### 4. Growth: mainly Meta paid acquisition - **Meta ads (confirmed)** : searching "zumdaten" in the Meta Ad Library (Germany, including stopped ads) shows 26 ad groups on the first screen, run under two page names in succession: - "ZumDaten - Flirte in deiner Nähe": from 2025-12-05, a new creative wave 1–February; most ran until 2026-07-20~24; - "ZumDaten - Flirten & Chatten": new creative waves in 2026-08-16, 09-02 and 10-03; most of the 10-03 batch stopped by 11-01, and as of 11-06 only 2 ad groups were still running. - Uniform copy: "Lust auf neue Begegnungen? Entdecke Singles in deiner Nähe und starte ein Gespräch. 🥰"; many creatives have 2–6 versions (A/B testing). - Source: [www.facebook.com/ads/library/?active_status=all&ad_type=all&…](https://www.facebook.com/ads/library/?active_status=all&ad_type=all&country=DE&q=zumdaten&search_type=keyword_unordered) (read 2026-11-06) - Timing lines up: Meta ads 11-01 mass-paused, and in our library, the daily new count for 11-05/11-06 fell from about 200 to about 100–125. - Ads stopped at the end of July → 8-03 the store listing date was reset → 8-16 new page name, ads resumed. This is right after Watchlist Internet named zumdaten (early July). Whether the rebrand was because of that article is **unverified** ; only the timeline matches. - **Instagram @zumdaten** : 7,400+ followers, 0 posts, a typical account used only to host ads; the followers likely come from ad engagement. Source: Jina search result summary. - **TikTok (Europe) and Google Ads** : checked in our tiktokads / googleads libraries, 2026-11-02 both returned no_ads (no advertiser under the company name, product name or domain). - **Fake private dating ads to drive traffic (user report, unverified)** : A one-star Trustpilot review from 2026-03-06 says that after leaving a message on a private dating ad, they got an email reply with a zumdaten link asking them to chat on the site. The reviewer believes the operator is generating leads this way. - **Payment demand emails (media reports)** : Watchlist Internet (2026-07) and netzwelt.de (2026-07-03) report that many non-registrants received "membership fee" bills and collection emails from zumdaten.com / michverlieben.com, amounts in the hundreds of euros. A Trustpilot review 2026-04-24 also says "never registered, dozens of emails and payment demands a day." Whether zumdaten.com is the same operator as zumdaten.de / this app is **unverified** . - No creator, Reddit, X or SEO content placements found; x-radar shows 90 posts in the last 0 days. ### 5. Where the money comes from Acquisition cost comes from Meta ads (Germany, men, "singles nearby"). New users, right after signing up, get "someone likes you / sent you a message" alerts, and replying costs coins, 10 coins per message. The other side is company-paid writers (mostly remote, low-paid "chat writers") whose job is to drag out conversations, stop users moving to WhatsApp, and push gifts and photo unlocks. A paying user may spend tens to hundreds of euros, so 15k installs is enough to reach around #30 in German Dating Top Grossing. Costs are ads + writer wages + payment fees, and there is no real network effect needed. **Cold start doesn't need a two-sided market** , which is why one shell after another can be copied. ### 6. Why it ran (summary) 1. **A monetization model, not a product** : the AGB states hosts + pay-per-message, so chart rank far exceeds install scale (Top Grossing 33 vs 4.82M installs on Top Free). 2. **Continuous Meta acquisition** : from 2025-12 on, new creative batches almost nonstop every 1–2 months; stop the ads and installs drop. 3. **Low barrier in Germany + an old brand** : the bar to reach around #30 in German Play Dating Top Grossing is not high. The zumdaten brand has existed for 2022 years and was made into an app after moving to the new Cypriot company. 4. **The shell can be copied** : Solvico Ltd at the same address shipped HERZY in 2026-08/09 and 18, same playbook. ### 7. How many people have seen it - Revenue isn't public; no X or TrustMRR discussion; - But it has been named in **consumer protection circles** : Watchlist Internet (Austria, 2026-07) and netzwelt.de (2026-07-03) used zumdaten as a fraud warning example; Trustpilot 4 reviews average 2.6 stars. - The business itself has been repeatedly exposed in German media (NDR, Stern, Verbraucherzentrale), so it is **far from a blue ocean** . ### 8. What to borrow - The only things worth copying are the distribution and pricing engineering: concentrated single-country Meta spend, frequent creative rotation with A/B tests, pay-per-use hooks like the "daily wheel", "see who viewed you" and gifts, and measuring unit economics by chart rank rather than install count. - The core relies on unlabeled, employed writers posing as real people, which carries legal risk under EU consumer protection and unfair commercial practice rules (Watchlist argues the contract terms may not be valid), and Google Play may delist it. **Copying the business itself is not recommended** . The compliant near-equivalent is **clearly labeled AI / virtual companion chat** (pay-per-message AI chat), which is long-standing paid demand on German Dating Top Grossing. ### 9. Uncertain - Coin pricing and actual revenue are unknown; no revenue estimate from chart rank was made. - Whether the zumdaten.com collection emails and this app share an operator is unverified; the fake dating ad lead-gen rests on a single user report. - It's unclear whether the ads from 2025-12 to 2026-01 pointed to the web version or the old app; the reason for the 8-03 store listing reset (changed info or re-listing) is unverified. - The link between M.M Spacecore and Solvico rests only on the same registered address and the same "marketing agency" pitch; it may just be a shared registered-agent address. - Who operated it before 2025-12 (the old company period) was not checked. ### Sources - Google Play page: [play.google.com/store/apps/details?id=com.zumdaten.app](https://play.google.com/store/apps/details?id=com.zumdaten.app) - Our data: googleplay (app_day, chart_rank, app_profile, 2026-10-29~11-06); tiktokads / googleads adv_map (2026-11-02 no_ads) - AGB / footer: [zumdaten.de/agb](https://zumdaten.de/agb), [zumdaten.de/impressum](https://zumdaten.de/impressum) - Meta Ad Library: [www.facebook.com/ads/library/?active_status=all&ad_type=all&…](https://www.facebook.com/ads/library/?active_status=all&ad_type=all&country=DE&q=zumdaten&search_type=keyword_unordered) - Company: [companieshousecyprus.com/company/m-m-spacecore-ltd-he482679](https://companieshousecyprus.com/company/m-m-spacecore-ltd-he482679), [companiesregistry.cy/company-details/m-m-spacecore-ltd-48267…](https://companiesregistry.cy/company-details/m-m-spacecore-ltd-482679/), [mm-spacecore.com/?page_id=446](https://mm-spacecore.com/?page_id=446) - Sister shells: [cyprusregistry.com/companies/HE/474954](https://cyprusregistry.com/companies/HE/474954) (Solvico Ltd, same address), [play.google.com/store/apps/details?id=com.nyu.herzy](https://play.google.com/store/apps/details?id=com.nyu.herzy) - Trustpilot:[www.trustpilot.com/review/zumdaten.de](https://www.trustpilot.com/review/zumdaten.de) - Watchlist Internet: [www.watchlist-internet.at/news/falsche-zahlungsaufforderunge…](https://www.watchlist-internet.at/news/falsche-zahlungsaufforderungen-von-datingplattformen/), [www.watchlist-internet.at/news/vorsicht-vor-coin-fallen-auf-…](https://www.watchlist-internet.at/news/vorsicht-vor-coin-fallen-auf-dating-portalen/) - netzwelt:[www.netzwelt.de/news/255861-spiel-liebe-diesen-dating-seiten…](https://www.netzwelt.de/news/255861-spiel-liebe-diesen-dating-seiten-chattet-erlebt-teures-erwachen.html) - Same template AGB: [flirtduo.de/agb](https://flirtduo.de/agb), [www.snoggle.app/agb](https://www.snoggle.app/agb), [e-commerce-kanzlei.de/appspartner-iflirts-app](https://e-commerce-kanzlei.de/appspartner-iflirts-app) This article was written by AI from public data and the data we collect daily.
