<Key Takeaways/>

  • Resolved sync failures caused by inconsistent email protocol handling across mobile and desktop

  • Validated encryption workflows to ensure sensitive user data was protected end-to-end

  • Automated privacy-critical test cases across platforms to catch issues before release

  • Improved QA-dev collaboration via daily bug reports and real-time tracking in Google Sheets

  • Uncovered edge-case failures through rigorous cross-browser and input validation testing

Complex protocols, highs security, and zero margin for error

Privacy Everywhere is a Denmark-based company behind Arca, a secure email app for mobile and desktop. Before launch, they needed to solve cross-platform sync, encryption, and privacy compliance without slowing release speed

Challenge

From day one, our team recognized the unique pressures Arca faced:

  • Ensuring cross-platform performance without data leakage

  • Handling email protocol complexities that can easily break sync logic

  • Delivering fast, accurate regression testing ahead of tight release windows

What made this even more critical? Arca users trust the platform to handle their most sensitive communications. Any glitch no matter how small could erode that trust

Privacy-centric testing with speed and precision

We kicked off the engagement with a deep dive into Arca’s architecture, studying its security layers and identifying integration points that needed special attention. Drawing on our ready-to-deploy frameworks in Selenium and Appium, we designed a multi-tiered testing strategy

Solution

  • Security-first test planning to validate encryption, authentication, and user control mechanisms

  • Automated regression cycles across mobile and desktop, customized for each platform

  • Real-time bug reporting via Google Sheets and collaborative tracking tools

  • Seamless CI/CD pipeline integration, ensuring automated testing post every build

By leveraging our flexible automation tools and real-time communication model, we helped the Arca team move faster without cutting corners

PerfectQA's automation testing solutions have brought a new level of efficiency to our QA processes. Their team is professional, detailed, and a pleasure to collaborate with. Highly recommend!

Secured performance and trust across every platform

In just six weeks, PerfectQA’s testing efforts helped Arca transform their QA process and launched with strong platform stability, secure data flows, and high user trust. The QA effort reduced regression cycles, uncovered critical sync bugs early, and enabled smoother release management with clear, real-time feedback for developers

Results

  • Achieved 90% functional test coverage, ensuring all critical and edge-case scenarios were validated before release

  • Delivered 30% faster bug resolution through real-time alerts and proactive debugging workflows

  • Ensured zero sync failures post-release across iOS, Android, and desktop environments

  • Reduced the regression cycle by 50%, allowing the development team to focus on building new features instead of rework


Every product operates with different constraints, timelines, and risks. While the outcome here was achieved in a specific context, the approach is designed to adapt to varying architectures, team structures, and release cycles
