Method, privacy, and limits
The pinned mapping is International Morse for A–Z and 0–9. Audio is synthesized locally with the Web Audio API. Timing uses the standard PARIS relationship of dot length = 1,200 ÷ WPM milliseconds; a dash is three units, with one-unit inter-element gaps.
V1 bounds speed to 5–40 WPM and tone to 400, 600, or 800 Hz. This is general practice, not certified radio-exam equipment. Typed answers, scores, streaks, and audio state stay in memory only; there is no storage, analytics payload, account, or microphone access.
