Praecheck

GETTING STARTED & LICENSING Praecheck is free to download. A Personal licence (£14.99, one-off purchase) is required to perform assessments. Licences are available separately from the Praescius website, listed under Developer contact on this Google Play page. This version does not offer in-app purchases. Each Personal licence supports two Android devices. Activate through your browser and import the signed, device-specific licence file (.pcl). Each device requires its own activation file. SEE BEYOND PERMISSIONS Android permissions tell you what an app may access, but they do not reveal the full picture. Praecheck is an independent, entirely offline Android data-exposure assessment tool. It examines the technical characteristics of installed apps and your device to help you understand potential privacy and security exposure. Rather than combining unrelated risks into one score, Praecheck separates its findings into three assessment areas. THREE AREAS OF ASSESSMENT 1. CORE EXPOSURE Reviews observable Android settings and granted access, including permissions, special access, connectivity and device configuration. 2. DATA CORRELATION EXPOSURE Examines installed-app and embedded SDK capabilities that could support profiling, identity linkage, attribution or data enrichment. These findings describe technical capability, not proof that an app has collected or shared your information. 3. KNOWN SOFTWARE RISKS Matches identifiable embedded component versions against Praecheck's bundled offline advisory catalogue, providing supporting evidence and confidence information. WHAT DOES PRAECHECK EXAMINE? • Sensitive permissions and special access • Installed-app characteristics and declarations • Embedded components and SDK capabilities • Wi-Fi, VPN, DNS, Bluetooth and nearby-device conditions • Changes between compatible assessments • New, returned and resolved findings • Known software-version vulnerabilities • Advisory dataset freshness • Detailed evidence exportable to CSV Findings include clear explanations and practical actions you can consider. PRIVACY BY DESIGN Praecheck examines apps at a technical level, not their private contents. It does not read your messages, photographs, passwords, banking information or private app data. The production application does not request Android's INTERNET permission. Assessment processing happens locally, and your results and comparison history are not uploaded to a remote scanning service. Purchasing and licence activation take place separately through your browser. UNDERSTANDING YOUR RESULTS Praecheck distinguishes between observable device conditions, potential data-correlation capabilities and known software risks. A correlation finding does not prove that an app or SDK collected, transmitted, sold or shared data. Likewise, matching a component version to a software advisory does not establish exploitation or device compromise. Praecheck is a data-exposure assessment tool, not antivirus, malware or spyware detection software, a forensic examination service, or a guarantee that your device is secure.
