AdGuard vs 1Password

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.

1Password can never read your saved passwords — they're end-to-end encrypted and even 1Password holds no keys — but outside the vault, the company collects substantial usage and diagnostic data, shares information with advertising partners in ways that may legally count as a data sale, and applies vague retention language to everything that isn't your vault content.
