FAQ

Is flash card data uploaded?

No. All content is generated and rendered locally in your browser. Nothing is sent to any server.

What display modes are available?

Four modes: numbers only (0–9), uppercase letters (A–Z), lowercase letters (a–z), and mixed numbers + letters.

Can I adjust the switch interval?

Yes, drag the slider to set any interval from 1 to 30 seconds to suit different age groups.

Can animal or plant cards be added later?

Yes. The shared data-source API can register animal, plant, text, emoji, or image cards without rewriting playback and fullscreen behavior.
