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. | | | What if I lose my activation email
