App Analytics with TelemetryDeck: Privacy-Focused Tracking for Developers
Over 3,300 developers worldwide rely on TelemetryDeck to process millions of user events each month. This German platform stands out for its emphasis on privacy, using techniques like on-device data anonymization to avoid collecting personal information. Developers integrate it into mobile apps and websites without needing cookie banners or wrestling with complex compliance requirements.
Launched from Augsburg, TelemetryDeck addresses a common pain point: gaining actionable insights into user behavior while respecting regulations such as GDPR. Its cookieless approach means no tracking of individuals, just aggregated signals about app usage. Setup takes under four minutes, and SDKs cover major platforms. The service has grown steadily since its inception, attracting indie developers and larger firms alike. With data hosted in Europe, it aligns with data sovereignty preferences. This setup lets teams focus on product improvements rather than legal hurdles.
What is TelemetryDeck?
TelemetryDeck is a SaaS analytics platform designed for mobile apps, web apps, and websites. It tracks events, funnels, retention rates, and other metrics through lightweight SDK integrations. Data gets anonymized on the user's device using double-hashing before any transmission, ensuring no personal details reach the servers.
Daniel Jilg began developing the software in summer 2020 from his home in Augsburg, Germany. His planned world trip fell through due to COVID-19 lockdowns, so he built the analytics tool he felt was missing for app developers—simple, private, and effective. In spring 2021, he co-founded TelemetryDeck GmbH with Lisa Figas, who brought expertise in cybersecurity and privacy. The company is headquartered at Von-der-Tann-Str. 54, 86159 Augsburg, with a presence in Hamburg.
TelemetryDeck prioritizes ethical operations, diversity, and openness. It offers SDKs for iOS/macOS/visionOS (Swift), Android/Kotlin, React Native, Flutter, and web/JavaScript/Vue. Users access a visual query editor and the TelemetryDeck Query Language (TQL) for custom analysis. Pre-built dashboards cover daily active users (DAU), monthly active users (MAU), crashes, and purchases. Additional tools handle funnels, A/B testing, retention, custom events, and activation tracking. Automatic metadata includes OS versions, device models, and anonymized IDs. A free tier supports up to 100,000 signals per month, with paid options scaling higher. Data centers in Germany use AWS, Hetzner, and Microsoft infrastructure for EU-compliant storage.
Who Uses TelemetryDeck?
TelemetryDeck serves indie developers, startups, enterprises, agencies, and sectors like fintech, healthcare, and e-commerce. Solo creators appreciate the free tier for early validation, while teams at scale use it for production insights.
Notable users include Panic Inc., known for Transmit and other Mac apps; Jamf, a leader in Apple device management; AltStore, the sideloading app store; and Stadtwerke Augsburg, a local utilities provider. These span software tools, enterprise IT, and public services. Developers choose it to monitor crashes, user retention, and feature adoption without privacy trade-offs. For e-commerce, it tracks carts and purchases; in healthcare, activation rates; in fintech, secure event logging.
European Advantage
Based in Augsburg, Germany, TelemetryDeck GmbH keeps data within the EU on providers like Hetzner and AWS Frankfurt. This ensures data sovereignty and full GDPR alignment, plus compatibility with DPA, TADPF, DPF, CCPA, and PECR. No cross-border transfers mean fewer compliance risks.
The German team understands EU privacy nuances firsthand. Awards like the Augusta Wirtschaftspreis für Frauen, CDR Corporate Digital Responsibility Award 2024, and MyData Award 2025 recognize this focus. Developers avoid U.S.-based tools' pitfalls, such as Schrems II challenges, gaining trust from European users.
How TelemetryDeck Compares
TelemetryDeck positions between simple web analytics like Plausible and feature-heavy options like Mixpanel. Unlike Plausible's lightweight web focus, it handles mobile SDKs and app-specific metrics like crashes. Matomo offers self-hosting for control, but requires infrastructure management—TelemetryDeck is fully managed SaaS.
Against Mixpanel, TelemetryDeck skips cookies and user profiles, using hashed signals instead. Its on-device privacy exceeds typical enterprise tools, with quicker setup and lower costs for indies. Free tier to 100K signals beats Plausible's limits, while TQL rivals Mixpanel's querying without the bloat.
