What it does

Built for mobile teams

01

Deep Linking

Universal links and app links that work across every platform and edge case. Deferred, contextual, and fallback routing included. Users land exactly where they should, whether the app is installed or not.

02

Deterministic Attribution

First-party, cookie-free attribution that tracks the full journey from ad click to in-app event. No fingerprinting, no probabilistic modeling. You see exactly which campaigns drive installs and revenue.

03

Revenue Analytics

Track in-app purchases, subscriptions, and custom revenue events. Match revenue back to specific campaigns and calculate true ROAS from real transactions, not modeled estimates.

04

EU-hosted Infrastructure

All data stays in the EU. GDPR-compliant by architecture, not by policy. No data leaves your control, no third-party processors in the chain. Schrems II compliant out of the box.

Takeaways

What we learned

01

Own your data

Building an attribution platform taught us that the biggest value is not the tracking itself — it is giving teams full ownership of their data without vendor lock-in or black-box algorithms.

02

Privacy by architecture

GDPR compliance is not a checkbox. We designed the entire system so personal data never leaves the customer's control. No workarounds, no exceptions.

03

Scale from day one

Processing millions of events daily forced us to make every architectural decision with throughput in mind. The result is a system that handles spikes without breaking a sweat.
