TelemetryDeck is a revolutionary privacy-first analytics platform specifically designed for app developers who want to understand user behavior without compromising user privacy. Founded during the COVID-19 lockdown by Daniel and Lisa, two privacy advocates with extensive backgrounds in app development and cybersecurity, TelemetryDeck addresses the growing need for GDPR-compliant analytics solutions. The platform offers cookieless tracking, meaning no personal data is stored in cookies, eliminating the need for annoying consent banners and complex compliance procedures. With support for iOS, macOS, visionOS, Android, React Native, Flutter, and web platforms, TelemetryDeck provides comprehensive SDKs that can be integrated in under 4 minutes. The platform automatically anonymizes all user data while still providing meaningful insights through pre-made dashboards, retention analysis, event tracking, and custom insights creation. TelemetryDeck serves thousands of organizations worldwide, from indie developers to enterprise clients, offering a lean alternative to complex analytics solutions like Firebase Analytics and Mixpanel. The platform's commitment to privacy-by-design makes it particularly valuable for companies operating in regulated industries or those targeting privacy-conscious users in Europe and beyond.
