This Startup is Optimizing User Engagement for a Global Audience
Onur Guven, CPO & Co-Founder Carbon Centrum shares his experience with TelemetryDeck.

Carbon Centrum is on a mission to reduce carbon emissions
CarbonID, developed by Carbon Centrum, is a unique mobile platform that empowers companies to incentivize their employees and customers to make more sustainable decisions by autonomously tracking CO2 footprints.

CarbonID
Track your CO2 footprint
By analyzing real-time user data, CarbonID creates certified CarbonIDs that help users reduce their carbon emissions and make eco-friendly choices.
Fully GDPR-compliant, CarbonID’s calculation methodology is designed for global applicability, ensuring accurate carbon footprint tracking across all operational locations.
Our app primarily targets environmentally conscious individuals, sustainability enthusiasts, and anyone interested in making eco-friendly lifestyle changes. We also appeal to a broader audience who are becoming more aware of their environmental impact and seeking practical tools to help them live more sustainably.
We launched CarbonID initially in the Nordic region (Norway, Sweden, Finland) and have just expanded our rollout to all countries in August 2024. While it’s too early to provide specific user numbers, we’ve already gained momentum, and the initial response has been very promising. We anticipate continued strong growth as we expand globally.
How to decide on an app analytics solution while deeply caring for privacy
We were looking for an analytics solution that would allow us to gather detailed insights into how people interact with our app. Specifically, we needed a tool that could provide metrics on individual screen usage, help us build funnels to identify where users might be dropping off, and ultimately guide our efforts to improve user engagement.
Privacy was also a critical factor for us, as we wanted to ensure that any data we collected was fully compliant with GDPR and respected our users’ privacy. Our users trust us with their data, and we are committed to ensuring that this trust is never compromised.
TelemetryDeck, with its strong focus on GDPR compliance and its roots in Europe, was the perfect fit for our needs.
While tools like Mixpanel, Amplitude, or Firebase Analytics offer robust analytics capabilities, they are not based in Europe, and we had concerns about their ability to fully align with GDPR requirements. We wanted an analytics solution from a company within the EU, one that truly understands and lives by the stringent data protection regulations.
TelemetryDeck's Support to the Rescue: Separating Test Data
Our mobile dev team hadn’t used TelemetryDeck before, but they found the documentation clear and easy to understand, which encouraged us to start the onboarding process.
Despite being new to the tool, the setup turned out to be pretty easy, and we were able to integrate TelemetryDeck smoothly without any issues.
We had a funny challenge early on—we forgot to turn on the Test mode before releasing the app to the App Store, which was fine at first. However, when we prepared the next version and started running automated tests for UI improvements, we suddenly saw 20-30 new “users” pop up out of nowhere! It was quite surprising, but then we realized it was because the Test mode wasn’t activated. Thanks to the TelemetryDeck team, we were able to separate these test data points from the actual user data.
Turning Data into Engagement with Funnel Tracking
We use TelemetryDeck daily to monitor how users interact with our app, track key performance metrics, and identify areas where we can improve the user experience. The insights we gain from TelemetryDeck help us make data-driven decisions, whether it’s optimizing specific screens, refining user flows, or understanding where users might be dropping off. It’s an integral part of our workflow, enabling us to continuously improve CarbonID and deliver a better experience for our users.
A key metric we’ve significantly improved with TelemetryDeck is user engagement. We created funnels to track where users were dropping off, which allowed us to pinpoint specific friction points in the user journey. By bringing together our product design and development teams, we were able to brainstorm and implement solutions that addressed these issues.
