AdGuard vs Bitdefender

AdGuard filters ads and trackers locally on your device so it never sees your browsing history, stores only an email address and password hash for account creation, keeps all personal data in its own data center in Frankfurt, names only payment processors as third-party recipients, and commits to emailing users before material policy changes — the main caveats are Cyprus jurisdiction, vague data retention periods, and a main policy that defers heavily to separate per-product privacy notices for the specifics of each platform.

Bitdefender is a Romanian cybersecurity company — EU member state jurisdiction, GDPR enforced by the Romanian DPA — with ISO 27001 and SOC2 Type 2 certifications, an explicit no-data-selling commitment, an anonymisation-first principle for technical data, and no advertising partner data sharing; the main caveats are that individual data processors are not named in the policy, technical security data can be retained for up to ten years, the website privacy policy explicitly provides no advance notice before changes, and marketing emails run on a legitimate interest basis for five years post-cancellation.
