Welcome to Certify Journey Hub (formerly CertFlow).
Your privacy is important to us. This Privacy Policy explains how Certify Journey Hub handles user information.
Certify Journey Hub does not itself collect, store, or share any personal information from users on our own servers.
We do not collect:
Payment information is handled entirely by Google Play (see "Purchases" below) — we never receive or store any payment details.
Study progress, certification tracking, user preferences, and app settings are stored locally on your device.
This information remains on your device and is not transmitted to our servers (we don't operate any).
Certify Journey Hub does not sell, rent, or trade user data. Data is only shared with the third-party services described below, as part of their normal operation.
The free version of the app shows ads served by Google AdMob. To show and measure ads, AdMob may collect device identifiers (such as the Android Advertising ID), approximate location, and app interaction data. This data is handled under Google's own privacy policy: https://policies.google.com/privacy.
You can review or reset your ad personalization settings in your device's Google settings at any time.
The optional Premium upgrade is a one-time in-app purchase processed entirely by Google Play Billing. We never see or store your payment card details. Your Premium entitlement is verified directly with Google Play each time the app checks it — we do not keep a copy of your purchase on any server of ours.
Beyond AdMob and Google Play Billing described above, Certify Journey Hub does not use third-party analytics or tracking services.
If additional third-party services are added in future versions of the app, this Privacy Policy will be updated accordingly.
While Certify Journey Hub does not transmit your study data to external servers, we follow industry-standard development practices to help protect information stored on your device.
Certify Journey Hub is not specifically directed toward children under the age of 13 and does not knowingly collect personal information from children.
We may update this Privacy Policy from time to time. Any changes will be posted on this page, along with an updated revision date.
