Information We Collect

Website

Our marketing website uses cookies for analytics and functionality. When you visit our site, you'll see a cookie consent banner that gives you control over which cookies are used:

Essential Cookies: Required for basic website functionality and remembering your cookie preferences
Analytics Cookies: Used by Google Analytics to understand how visitors use our site (only with your consent)

Google Analytics data is anonymised and aggregated, and includes information about your browser type, device, pages visited, and time spent on our site. We do not collect personal information through website analytics.

You can accept or reject analytics cookies at any time through the cookie consent banner. If you reject analytics cookies, no tracking scripts will be loaded, and any existing analytics cookies will be immediately removed. Your consent preferences are stored for 1 year (accept) or 7 days (reject).

Mobile App

User Profile Information: When you set up your profile, we store information such as your name, company details, contact information, and professional registration locally on your device. This information is used to optionally pre-populate certificates and is not shared with third parties.
Certificate Data: All certificate data you create is stored locally on your device and is not transmitted to our servers. This includes client information, installation details, test results, and professional information. You have complete control over this data and delete it at any time (or export it if you have unlocked the paid features).
Anonymous Crash Reports: We also use Sentry to collect anonymous crash reports and performance data to help us improve the app's stability. This data is automatically anonymised and does not contain any personal information or certificate data. It includes technical information about device type, operating system version, and error details only.
