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. |

The application contacts the vendor’s activation server (HTTPS) and validates the key against the server‑side database. 4.

Volume or site licenses are not officially offered, though resellers sometimes bundle multiple keys. | | Renewal/Support | The key does not expire; support is provided for the lifespan of the major version (e.g., 15.x). Minor updates are free; major upgrades (e.g., to version 16) require a new key/purchase. | 5.

1. User clicks “Activate” → UI prompts for 25‑char key. 2. App builds JSON payload: "product":"Abviewer15", "key":"ABV15‑X3J9K‑L8M2P‑Q4R6S‑T7U8V", "hw_fingerprint":"9F2C5E7A..." 3.
