What Silphe records
When you play, Silphe records the path of your pointer — positions and timestamps — and a few per-task numbers (reaction time, accuracy, tremor, tracking). That's all.
Where it goes
Nowhere. It is written to a recordings folder on your own machine and stays there. There is:
- No cloud upload.
- No telemetry, no analytics, no "anonymized" exhaust.
- No account, no login, no network calls at all for the core capture, analysis, and arc view.
Why this matters
The exact wobble of your hand is about as personal as data gets — it can reveal fatigue, intoxication, and motor or cognitive change. That is precisely why Silphe is built local-first. Your signature is yours.
Your data, your control
The recordings are plain text (JSONL) on your disk. Read them, move them, or delete them whenever you like — they're just files.
