Last updated: June 2026
Short version: CertLab does not collect, transmit, or store any of your data on external servers. Everything stays on your device.
CertLab does not collect any personal information. We do not have servers, databases, or any backend infrastructure for this app.
Your quiz history, settings, and saved progress are stored entirely on your device using local storage.
CertLab does not include any analytics SDKs, crash reporters, or advertising frameworks. We do not track your usage, behavior, or any other activity within the app.
Because we collect no data, there is nothing to share with third parties.
If anything changes, we will update this page. The date at the top reflects when it was last revised.
