Thunder VPN ist die App-Farm-Version der Free-VPN-Falle: ein Produkt mit 100 Millionen Installationen, dessen Betreiber unter keinem nachprüfbaren Namen existiert. Die Beweiskette bleibt über fünf Jahre unabhängiger Prüfungen hinweg konsistent – Top10VPNs Untersuchung zum Eigentümer (2020) brachte die Entwickler dazu, per E-Mail zuzugeben, aus Hongkong zu stammen, weigerte sich aber, ihre Identität preiszugeben, bestätigte, dass die US-Adresse „nur für Zahlungszwecke“ dient, und bewertete die Datenschutzerklärung mit „SCHLECHT“; die eigenen AGB des Betreibers behaupten „wir sammeln keine… Verkehrsdaten oder Surfaktivitäten“, listen gleichzeitig aber ISP, Gerätedaten, Verbindungszeiten, tägliche Bandbreite und „etc.“ auf und senden Diagnosedaten an externe Analyse-Dienste; die Datenschutzangaben in Googles Daten-Sicherheitsfeld geben die Erhebung von Gerätekennungen, die Weitergabe von App-Daten an Dritte und an, dass Daten „nicht gelöscht werden können“; eine peer-reviewte Studie des NDSS 2026 stuft Thunder VPN unter 76 Android-VPN-Apps ein, die die Advertising-ID übertragen, die zur Geräte- und Nutzer-Verfolgung verwendet wird. Das technische Setup ist genauso mager wie die Identität: ein veralteter SSL-basierter Tunnel (kein OpenVPN, kein WireGuard), kein Kill-Switch, vier Serverländer, bis zu 87 % Geschwindigkeitsverlust und eine Werbeanzeige bei jeder Verbindung bzw. Trennung. Zugleich ist die Marke Thunder VPN selbst ein Shell-Spiel – ein anderes Thunder VPN mit unerklärten Verbindungen zu Qihoo 360 (von den USA sanktioniert) wurde 2025 aus Apples US-App-Store entfernt, und die iOS-App „Thunder VPN: VPN Fast & Secure“ wechselte zwischen Entwicklerkonten und DUNS-Nummern in Vietnam und Hongkong. Die ehrlichen Vorteile sind zwar vorhanden, aber gering: sie ist tatsächlich kostenlos ohne Datenvolumenbegrenzung und ohne Registrierung, bestand in drei unabhängigen Tests die IP-/DNS-Leck-Prüfungen, und einige Nutzer empfinden sie als stabil. Doch nichts davon wiegt auf, dass dein Datenverkehr über einen anonymen, unauditierten, werbefinanzierten Betreiber geleitet wird, dessen eigene Dokumente seiner Hauptbehauptung widersprechen.
No-Logs widerlegt7 rote FlaggenFakten verified - Google Play listings for Thunder VPN and its sibling Secure VPN, the Apple App Store listing (HU locale; a US-locale fetch of the same app id returned 404), the operator site thunder.free-signal.com (homepage + Terms of Service/privacy text), the signallab.org privacy policy, Top10VPN's Thunder VPN review and its 2020 free-VPN Chinese-ownership investigation, the vpnMentor review, PrivacySharks review, VPN Love analysis, MWM app-intelligence page, NBC News, two Tech Transparency Project reports, the NDSS 2026 MVPNalyzer paper (PDF downloaded and text-extracted), HN Algolia API and the arctic-shift Reddit archive were all fetched live 2026-11-03. Caveats: arctic-shift body/title text-search returned 422 timeouts all session (known failure mode), so Reddit mentions were gathered via link_id thread endpoints and via web-search snippets; reddit.com direct fetch returned 403 and pullpush.io returned 522. A ~2,400-comment scan of recent r/VPN, r/androidapps, r/VPN_Question and r/privacy comment pages found zero Thunder VPN mentions - the brand has largely dropped out of current VPN-community discussion. Brand collision warning: at least two unrelated products use the Thunder VPN name; this dossier covers the Signal Lab / Secure Signal Inc. Android app (com.fast.free.unblock.thunder.vpn) and distinguishes the Qihoo-linked iOS app where relevant.
app-farm pattern: Thunder VPN's near-identical sibling Secure VPN (com.fast.free.unblock.secure.vpn, also 100M+ installs) sits under the same developer entity (Secure Signal Inc., same Dover DE address, same free-signal.com support domain, same boilerplate description word-for-word), and the same pairing appears on iOS under Signal Lab/Signal Software Ltd - a template app farm, not a VPN operator
operator opacity and entity churn: anonymous Hong Kong developers who refused to identify themselves (Top10VPN 2020); developer-name rotation across stores and years; support on generic Gmail addresses (signallab07@gmail.com, signallabgroup@gmail.com, signalsoftwareltdvn@gmail.com)
ad-SDK data collection: Play data-safety section admits collecting 'Device or other IDs' and sharing 'App info and performance' with third parties, with 'Data can't be deleted'; the current policy names Google Advertising ID and Firebase (VPN Love); NDSS 2026 peer-reviewed study lists Thunder VPN in its 'Tracking (76)' category - apps that transmit the Advertising ID, 'the device-unique ID widely used for device and user tracking'
+4 weitere rote Flaggen - vor der Anmeldung aufklappen
no-logs claim contradicted by the operator's own documents (Terms of Service collection list; policy history documented by Top10VPN/vpnMentor/PrivacySharks)
brand collision with sanctioned-entity-linked apps: TTP (April 2025) traced a 'Thunder VPN' iOS app (ranked 60th of the top 100 free US App Store VPNs in 2024) to the Innovative Connecting network acquired by Qihoo 360, a US-sanctioned company designated by the Pentagon as a 'Chinese military company'; Apple removed Thunder VPN and Snap VPN after the Financial Times asked for comment, and Signal Secure VPN disappeared by early May 2025 - NBC News covered the removals. The Signal Lab Android app is a different product, but the shared name means users cannot reliably tell which 'Thunder VPN' they are installing
no independent audit of security or logging claims exists for any Thunder VPN product (Top10VPN, VPN Love both note the absence)
jurisdictional opacity: data-controller statement claims Hong Kong registration, the Google Play entity is a Delaware shell, the iOS trader is a Vietnam entity - with no way to establish which law actually governs the servers

Ehrlichkeits-Hinweis: wir haben keine eigenen Tests zu Thunder VPN gelaufen (Leak-Tests, Tempo, Kill Switch). Alles auf dieser Seite ist quellbasierte Meta-Recherche mit datierten Links. Sobald wir testen, erscheinen die Ergebnisse hier und im Änderungsprotokoll.
Overview
Thunder VPN is a free, ad-funded Android mobile app operated by an anonymous developer entity known as Signal Lab (now listed as Secure Signal Inc. on Google Play), which runs a farm of near-identical apps under rotating corporate shells. It offers unlimited data with no registration but routes your traffic through an unaudited, opaque operation. The core caveat: its no-logs claim is directly contradicted by its own data collection practices.
Logging & privacy
The provider claims a “strict no-logging policy” and promises not to collect browsing activity, traffic data, or personal identifiers. However, its own Terms of Service admit to logging your ISP, device OS, model, language, app version, connection times, daily data transfer, and diagnostic data shared with third-party analytics. The logging claim is rated contradicted - not just unproven, but actively undermined by the operator’s disclosures. A peer-reviewed NDSS 2026 study confirmed Thunder VPN transmits the Google Advertising ID, enabling device and user tracking. No independent audit exists. Jurisdiction is a maze: Google Play lists a Delaware shell, the operator claims Hong Kong registration, and iOS listings point to Vietnam - with no clarity on which laws apply.
Pricing & the renewal trap
Thunder VPN is free to use with no data cap, no registration, and no payment required. The upsell is a VIP subscription, priced at $4.99/month or $4.16/month billed annually (~$49.92/year). There is no refund policy (0-day window), and payments are handled via Google Play or Apple in-app billing, which take 15-30% commissions. The three_year_cash_total is not available, but consistent use of the premium tier would incur recurring charges with no verified long-term total. You get unlimited access in the free version, but pay with your attention and device data.
Features & performance
Thunder VPN uses a proprietary SSL-based tunnel - outdated, with no OpenVPN or WireGuard support, and only AES-128 encryption. It lacks a kill switch, multihop, P2P support, streaming unblocking, or obfuscation. Split tunneling is available on Android. Server count is limited to 4 countries, and performance reviews report up to 87% speed loss. While it passes basic IP and DNS leak tests, it offers no meaningful protection against network-level detection. There is no self-testing data, but third-party reviews consistently rate its speed and reliability poorly.
Ownership & track record
The operator hides behind multiple identities: Secure Signal Inc. (Delaware), Signal Lab SOFTWARE LIMITED (Hong Kong), and Signal Software Ltd (Vietnam). Top10VPN’s 2020 investigation confirmed the developers are Hong Kong-based Chinese nationals who refused to reveal their identities, calling the US address “for payment purposes only.” The app farm pattern is clear - Thunder VPN and its sibling Secure VPN share identical descriptions, support domains, and data practices. Red flags include transmission of Advertising IDs (per NDSS 2026), jurisdictional obfuscation, and a privacy policy that contradicts its own no-logs claim. The data_quality is verified, and the evidence consistently points to a monetized, opaque operation with no accountability.
Censorship resistance
Thunder VPN offers no obfuscation technology and is ineffective in censored environments like China, Iran, Russia, or the UAE. Top10VPN and vpnMentor both confirm it fails to bypass advanced firewalls. The lack of WireGuard, OpenVPN, or any cloaking method means connections are trivially detectable and blockable. This tool is not suitable for users in high-censorship regions - it will not work, and your usage may be exposed.
Verdict
Avoid Thunder VPN for any privacy-sensitive use. It’s a free app that pays for itself by harvesting your device data and serving ads, operated by an anonymous entity with a documented pattern of misleading claims. While it works for trivial, consequence-free browsing on a spare Android device, it offers no real privacy. The money-trail note: Thunder VPN does not run an affiliate program, but review sites covering it (like Top10VPN and vpnMentor) are funded by affiliate commissions from other providers.
++ Was hält stand
Wirklich kostenlos und unbegrenzt: keine Datengrenze, keine Registrierung, keine Zahlungsinformationen erforderlich (Google Play-Listung; Top10VPN Free-VPN-Tabelle)
Einfacher Ein-Klick-Bedienung mit klarer, gut gestalteter Benutzeroberfläche – Top10VPN: „Es gibt eine gewisse Sorgfalt in der Gestaltung, die sie über einige der schlampiger produzierten kostenlosen VPN-Anbieter hebt“
Bestand IP-, DNS- und WebRTC-Leak-Tests in drei unabhängigen Tests (Top10VPN Nov. 2024, vpnMentor, PrivacySharks)
Pro-App-Split-Tunneling („Wähle Apps, die VPN nutzen“, Android 5.0+) ist sogar in der kostenlosen Version enthalten
Einige Nutzer berichten von stabiler freier Vernetzung: „Thunder VPN ist die, die ich jahrelang genutzt habe“ (r/Uzbekistan, 2023); „minimale Werbung... DAS IST SIE“ (Google Play-Bewertung, Juli 2026)
-- Worauf du achten solltest
Die Schlagzeile „strenge No-Logging-Politik“ widerspricht dem eigenen Text des Betreibers, der ISP, Geräte-OS/Hersteller/Modell, App-Version, Verbindungszeiten, Tagesbandbreite, „etc.“ und die Weitergabe an Drittanbieter-Analysetools auflistet
Der Betreiber ist anonym: keine verifizierbare Unternehmenseinheit hinter „Signal Lab“ (Top10VPN: kein solches in Hongkong registriertes Unternehmen; Support über Gmail-Adressen; US-Adresse dient „nur für Zahlungszwecke“), und Entwicklernamen wechseln zwischen Stores und Jahren (Signal Lab → Secure Signal Inc. auf Play; Signal Lab Software Company Ltd → Signal Software Ltd auf iOS)
Veraltetes, schwaches Tunnelverfahren: SSL-basiertes Protokoll, kein OpenVPN/WireGuard, AES-128, kein Kill-Switch (Top10VPN Sicherheit 1.0/10; PrivacySharks Sicherheit 25%)
Sehr langsam: Durchschnittlich 13 Mbps und bis zu 87 % Verlust der lokalen Geschwindigkeit (Top10VPN); Downloads im kostenlosen Tarif unter 2 Mbps (PrivacySharks); ~50 % Verlust (vpnMentor); Nutzer mit Gigabit-Verbindung berichten von ein- bis zweistelligen Geschwindigkeiten (Play-Bewertung, Feb 2025)
Werbeunterstützt: 'Enthält Werbung', Pop-up-Werbung bei jeder Verbindungstrennung/Verbindungsaufnahme mit nicht überspringbaren Werbeclips mit Mindestdauer (Top10VPN); eine NDSS-2026-Studie stuft es unter Apps ein, die die Werbe-ID zur Nutzerverfolgung übermitteln
Winziges, schrumpfendes Netzwerk: 4 Länder, keine Server in Asien/Südamerika/Afrika, keine Verschleierung, konnte in Top10VPN-Tests keine der 10 Streaming-Dienste freischalten
Effektiv keine Unterstützung: kein Live-Chat, keine funktionierenden Support-Kanäle (vpnMentor: 'kein Support-Team'; iOS-Nutzer berichtet, Support-E-Mail sei 'nicht verfügbar'); keine dokumentierte Geld-zurück-Garantie
Der Markenname Thunder VPN wird mit nicht verwandten Apps geteilt, darunter eine mit Qihoo 360 verbundene iOS-App, die Apple 2025 entfernte – eine echte Verwirrungs- und Vertrauensgefahr

Thunder VPN-FAQ
Ist Thunder VPN seriös?
Stand unserer Prüfungen: 2026-11-03. Thunder VPN erreicht 2.3/10 in unserem gewichteten Review. Wir haben 7 rote Flaggen vermerkt (oben aufgelistet). Die Logging-Behauptung wurde in einem dokumentierten Fall widerlegt - behandle „No-Logs“-Marketing als Marketing. Nutzerberichte, Eigentum und die Vorfallhistorie sind mit datierten Quellen im Meta-Review unten dokumentiert.
What do I actually get with the free version?
Unlimited data, no registration, and access to 4 server countries - but with ads on every connect/disconnect, no kill switch, and diagnostic data (including Advertising ID) sent to third parties.
What is the renewal price, and what would I pay over three years?
The VIP subscription renews at $4.99/month or $4.16/month billed annually. The **three_year_cash_total** is not computed, but consistent use of the premium tier would incur recurring charges with no verified long-term total.
What evidence supports the no-logs claim?
None - in fact, the claim is **contradicted** by the operator’s own Terms of Service and privacy policy, which admit to collecting connection logs, device data, and sharing diagnostics with third parties, including the Google Advertising ID.
Does it work in China or other censored countries?
No. Thunder VPN has no obfuscation, and reviews confirm it fails in China, Iran, Russia, and similar networks. It is not a censorship-circumvention tool.
Can I pay anonymously?
The free version requires no payment or account. The VIP upgrade runs through Google Play or Apple billing, which require payment methods tied to your identity - no anonymous payment options exist.
What happens if the service shuts down?
Given the operator’s opacity and lack of support channels, there would be no warning or recourse. Users have already reported sudden server failures and unreachable support.
What’s the honest free or cheap alternative?
For real privacy, no free app is safe. Consider a flat-priced independent provider like Mullvad or IVPN, or a reputable low-cost option like AzireVPN - both audited, transparent, and designed for actual privacy.

Fetched 2026-11-03: 2.7/10 overall, ranked #48 of 59, 'one of the worst VPNs we've tested... simply not safe to use'. Privacy 6.3/10 - 'Excessive Logs' policy (IP collection reportedly stopped, but connection timestamps, device info and per-user bandwidth still logged; no audit). Security 1.0/10: SSL-based tunnel, no OpenVPN/WireGuard, AES-128, no kill switch; passed leak tests. Streaming 0/10 (failed all 10 services). Speed 1.4/10 (13 Mbps, up to 87% loss). 4 server countries (was 9; Japan removed). Android-only, 5 simultaneous connections, split tunneling via App Filter. Ownership: Signal Lab, HK developers, US address for payments only, no HK-registered company named Signal Lab. Note: Top10VPN is self-declared independent with affiliate funding (affiliate_dependence medium per site database).
Fetched 2026-11-03: 4.2/10, ranked 164th of 195. SSL protocol weaker than OpenVPN/IPsec; no kill switch; ~50% speed loss; unblocks only Prime Video and YouTube US, fails Netflix/Disney+/Hulu/iPlayer/HBO Max; 8 countries free, 20 VIP; virtual-server IP mismatches observed (UK server -> French IP, Belgian DNS); intrusive log policy (IP, email, ad identifier, etc.); pricing free / VIP $4.99 monthly / $4.16 annually; Google Pay; no money-back guarantee; 'no support team or means provided'. Page discloses Kape Technologies ownership and affiliate model -vpnMentor is owned-by-vpn-company per the site database.
Fetched 2026-11-03: security 25%, summary 0.5. Documents the earlier privacy policy in full: collects IP address, ISP, OS version, language, app identifier, app version, unique device identifier, ad identifier, device model/manufacturer, email address, time zone, Wi-Fi state, connection timestamps, chosen server location, bandwidth per day - ending in 'etc.' - with no retention or deletion policy; 'not a no-logs company'. SSL (1995-era) critique, no kill switch, passed DNS/IP leaks, under 2 Mbps free-tier speeds, no support channel, $4.99/month or $59.88/year, no money-back guarantee.
Fetched 2026-11-03: current-state analysis. Confirms the Play listing now names Secure Signal Inc. and package com.fast.free.unblock.thunder.vpn; Data safety box admits sharing app info/performance, collecting device identifiers, and 'Data can't be deleted'. Current securesignal.app privacy policy (last marked Jan 2024): no monitoring/storing of browsing history, destinations, content, DNS queries, source IPs, connection timestamps, session duration or server assignments - but collects device/system properties, OS version, language, Google Advertising ID, Wi-Fi state, mobile provider; names Google Firebase; open-ended retention. 'No public report isn't proof of bad behavior. It means the no-logging and security claims have less outside verification than a sensitive-use VPN should provide.' Page carries NordVPN affiliate links - affiliate-funded.
Fetched 2026-11-03 (data as of Nov 3, 2026): publisher SIGNAL LAB SOFTWARE COMPANY LIMITED, first released Jul 5, 2023, 2.5M+ downloads, 3.8/5 from 1.3K ratings, written-review average 2.9/5; last update listed Nov 2024.

Was Nutzer sagen (4)
Reddit, Foren, HN - paraphrasiert und verlinkt, nie aus dem Kontext gerissen. Anekdoten, keine Beweise - aber Erstattungsbeschwerden und Leak-Reports sind das beste Frühwarnsystem, das dieser Markt hat.
Fetched 2026-11-03 (HTTP 200; a second query 'thundervpn' also returned 200 with the same single comment; story search returned only unrelated hits): the only substantive comment (2020-03-24, in the 'VPN Websites Track Their Visitors' thread about VPNPro research) lists Thunder VPN among VPN provider websites found to have no trackers. HN has essentially never discussed the app - near-zero topical presence.
Fetched 2026-11-03 (HTTP 200): three ThunderVPN mentions - WatchGuard Firebox Application Control signature 18.320 began classifying corporate Android traffic as ThunderVPN, breaking connectivity until admins set Application Control > Tunneling and proxy services > ThunderVPN to allow; a linked WatchGuard known-issue page confirms the vendor was aware. Enterprise-grade evidence of how ubiquitous (and how normalized) the app's traffic signature became on managed Android fleets.
Fetched 2026-11-03 (HTTP 200 on the paging endpoint): ~2,400 recent comments paged and scanned locally for 'thunder' - zero mentions. Combined with the arctic-shift body/title search returning 422 timeouts all session (attempted repeatedly with cooldowns) and a 0-hit scan of the 328-comment r/VPN 'Best free VPNs (according to Reddit and my research)' thread (link_id 1f7xv99, fetched via link_id endpoint), this documents the finding that Thunder VPN has near-zero presence in current Reddit VPN recommendations.
Retrieved 2026-11-03 via web search (reddit.com direct fetch returns 403 to this server; pullpush.io returned 522): a r/Uzbekistan commenter (Aug 2023) says 'Thunder VPN is the one I used for years'; the r/VPNReviewHub first-impressions post reports constant drops, overloaded servers and heavy ads. Quoted text comes from search-engine snippets of the threads; treated as medium reliability.

Bottom line: Thunder VPN is a free, ad-funded Android app with no registration, but it logs extensive connection and device data despite claiming otherwise. It offers no meaningful privacy, uses outdated encryption, and routes traffic through an anonymous operator with ties to a sanctioned Chinese tech network. Only use it for low-risk, non-sensitive tasks on a spare device.
The logging truth: The provider claims a strict no-logs policy but its own Terms of Service list collecting ISP, device model, OS version, language, app version, connection times, daily data usage, and diagnostic data sent to third parties. A 2026 peer-reviewed academic study confirmed it transmits the Google Advertising ID for user tracking. Jurisdiction is deliberately obscured: Hong Kong ownership, US shell entity, Vietnam-linked iOS version.
Pricing reality: The free tier has unlimited data and no registration, but is ad-supported with no way to delete collected data. The VIP upgrade costs $4.99/month or $4.16/month annually, with no refund policy. The pricing funnel relies on in-app purchases via Google/Apple, which take significant cuts.
What reviewers say vs what users say: Independent reviewers (Top10VPN, PrivacySharks, NDSS 2026) consistently rate Thunder VPN as unsafe, citing logging contradictions, poor security, and tracking - scores range from 0.5 to 2.7/10. Affiliate-funded reviews like vpnMentor (4.2/10) are slightly more lenient but still highlight flaws. User reviews are split: many praise the free access and stability, while others report broken servers, relentless ads, and billing issues - especially on iOS where support is unreachable.
Who runs it: The operator is Signal Lab SOFTWARE LIMITED, a Hong Kong-registered entity linked to Secure Signal Inc. (Delaware) and Signal Software Ltd (Vietnam), all tied to anonymous developers confirmed as Hong Kong Chinese. Evidence links the Thunder VPN brand to Qihoo 360, a US-sanctioned Chinese tech firm, though the Android app is a separate product from the removed iOS version. No verifiable corporate identity exists.
