TelemetryDeck

Product overview

TelemetryDeck is a privacy-first product analytics tool for app and web developers, based in Augsburg, Germany. It collects usage data (called signals) from apps and websites, then anonymizes everything through double-hashing so that individual users cannot be identified, even by TelemetryDeck itself. Because no personal data is processed, no cookie consent banner is required under GDPR. The platform covers core product analytics functions: event tracking, conversion funnels with statistical scoring, retention analysis, and experiment queries for comparing feature variants. It includes a visual query editor for building custom dashboards and pre-made templates for common metrics like monthly active users, error rates, and in-app purchases. A query language called TQL is available for advanced custom analyses. TelemetryDeck provides SDKs for Swift (iOS, macOS, visionOS), Kotlin (Android), React Native, Flutter, and JavaScript (web), with community SDKs for Unity and Rust. This makes it suited to indie developers and small-to-mid-size product teams building cross-platform apps. Notable users include Stadtwerke Augsburg (public transit) and Panic (Mac developer tools). The company was founded in 2020 by Daniel Jilg and Lisa Figas, and registered as a GmbH in Germany. The team has about six to eight people and is angel-funded. Revenue reached nearly 100,000 euros in 2024. A free plan includes 100,000 signals per month, with paid plans from approximately 9 euros per month.
