AdGuard vs Malwarebytes

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.

Malwarebytes has noticeably better specific privacy practices than comparable US security companies — IP addresses are explicitly not stored, the VPN has a detailed and specific no-logs commitment, text messages are scanned without being retained, cloud storage scan files are deleted immediately after scanning, and usage/threat statistics collection can be opted out of in product settings — but it is a US company (Santa Clara, CA) with no named security certifications in its policy, vague retention periods, and a website advertising tracking stack.
