A covered pick. Anyone can use it as a private drop-in, with no setup or know-how. Enough for most people. Threat levels
Our take
Tiny as open-source projects go, but that undersells it, because Euki is less a hobby project than a purpose-built tool for sexual and reproductive health where on-device storage genuinely protects users. Nothing you enter goes to the cloud, and it even has a decoy PIN for situations where someone might force the app open. Choose it when the threat you care about is another person physically checking your phone, not a server breach. Just know the content library matters as much as the privacy here.
