Local-first

Start now, add detail when ready

Begin or end an episode in seconds, then record intensity, locations, symptoms, observed factors, actions, and optional notes.

Facts, never medical conclusions

Review a searchable history and transparent 30- or 90-day summaries without trigger claims, predictions, diagnosis, or treatment advice.

Private, offline, and portable

Everything stays on your device; create text, CSV, or validated JSON exports and restore a backup only when you choose.
