Flashcards is a lightweight study app that lives entirely in your browser. Create as many decks as you like, add front-and-back cards, then study by flipping each card to reveal the answer. Shuffle the order for real recall practice, and mark each card as known or still learning to watch your progress. Every deck is saved to this device's local storage, so your work is still there when you come back, and you can export a deck as JSON to back it up or share it, or import one to pick up where you left off. Nothing is ever uploaded to a server.
Short answers for the questions people usually have before trying a utility like this.
Decks are saved in your browser's local storage on this device. They persist across reloads and are never uploaded anywhere, so they stay private to you.
