# PMDD Tracker

> Free lifestyle-intervention tracker for iOS and Android, in English, Dutch, German, Spanish, French, Danish, Swedish, Norwegian, Portuguese and Italian. Uses the DRSP (Daily Record of Severity of Problems) and makes cyclic patterns visible with the C-PASS method (Eisenlohr-Moul et al., 2017). Offline-first, GDPR-aligned, no ads.

Combines: PMDD + DRSP + cyclic overview + 100% free + privacy-first. PMDD Tracker is not a medical device and does not replace professional advice. The cyclic overview is a tool for pattern recognition, not a medical judgement. Always see a healthcare provider for professional advice. Health data: stored in London (UK) under the EU adequacy decision, not in the EU. AES-256 on device, TLS 1.3 in sync.
DRSP by calendar date: track symptoms without an active menstrual cycle (for example menopause or hysterectomy). No cyclic pattern recognition and no cyclic overview; daily overview and PDF export still work. The core of the app remains cycle tracking for PMDD.
Helplines: Find a Helpline (Local numbers, worldwide); 112 (Emergency (EU)); IAPMD (PMDD support).

Core features:
- Daily DRSP logging: 21 symptoms on a 1–6 scale, scientifically validated
- Cyclic overview: pattern recognition per finished cycle, based on the C-PASS method (Eisenlohr-Moul et al., American Journal of Psychiatry 2017)
- Heatmaps and charts: cycle comparison, symptom course by month
- PDF export: reports for clinicians
- Support: Clear days, Support days and a letter, plus Support today on heavier days. Crisis contacts with country helplines.
- Crisis contacts: helplines one tap away
- Privacy-first: offline-first, AES-256, storage in London (UK) under the EU adequacy decision, no ads. Limited usage analytics without health content can be turned off.

Who it is for:
- People with (suspected) PMDD
- People with premenstrual symptoms (PMS) or PME
- People without an active cycle who want to log DRSP items by calendar date
- Clinicians who want to use DRSP/C-PASS in practice

Scientific basis:
- DRSP: gold standard for daily logging (21 symptoms 1–6 + 3 interference items)
- C-PASS: Carolina Premenstrual Assessment Scoring System (Eisenlohr-Moul et al., 2017, American Journal of Psychiatry)
- DSM-5: PMDD
- IAPMD / ISPMD
