“Data Not Collected”

That's DecoEcho's App Store privacy label — a rarity in the education category. No servers, no accounts, no analytics, no ads. Your cards and study progress live on your device and in your own private iCloud. We never see them.

The story

Built the hard way

DecoEcho started as a personal frustration: flashcard apps that either looked like spreadsheets, buried features behind subscriptions, or quietly harvested user data. We built the study app we actually wanted — a smart spaced-repetition engine wrapped in a classic Miami Art Deco design, with a simple promise: your study data is yours alone.

There are no servers and no accounts, which means there is nothing to breach and nothing to sell. The free tier is a complete study tool, and one small one-time purchase unlocks everything else. No subscription, ever.
