All purchases are processed through the official website (HTTPS, PCI‑DSS compliant). Third‑party marketplaces occasionally list discounted keys, but they carry higher risk of fraud or invalidation. | Topic | Assessment | |-------|------------| | Key storage | Keys are never stored in plaintext on the user’s machine; only an encrypted activation file is written. | | Communication | Activation uses TLS 1.2+; no clear‑text credentials. | | Vulnerability history | No major CVEs reported for Abviewer 15 as of April 2026. Minor bugs (e.g., memory leak when opening large PDFs) have been patched in v15.3. | | Privacy | The activation request sends only a hardware hash and the key; no personal data is logged beyond the purchase email. | | Compliance | The software does not claim GDPR‑specific data‑processing capabilities, but the minimal data collection (hardware fingerprint) is within acceptable limits for a desktop utility. | Abviewer 15 Key
