Decoy is a privacy-first password and identity manager. Instead of handing every website your real email, Decoy creates a decoy email alias, a saved login, and 2FA codes — filled for you anywhere you sign up. • Decoy email aliases — give each site its own address; mail still reaches you. • AutoFill everywhere — logins, passwords, and 2FA codes, right in Safari and your apps. • A private inbox — read and reply to every alias's mail without exposing your real address. • End-to-end encrypted — everything is encrypted on your device. Decoy's servers store only ciphertext and can never read your data. • Works with the Decoy Chrome and Firefox extensions — pair once, sync everywhere.

Verdict
The clearest difference is update cadence: Decoy at every 3 days against Quackify's every 2 months. Quackify's advantage is iOS requirement (16.0 vs 26.2). On price, ads, in-app purchases and device support there is nothing between them.
