## Privacy

- All analysis runs locally
- Zero network requests
- No data leaves the machine

## Limitations

- Consumer arrays miss rare variants (~0.1% of genome)
- Results are probabilistic, not deterministic
- Not a medical diagnosis
- Most conditions 50-80% non-genetic
- Consult healthcare providers for medical decisions
- Negative hereditary cancer result does NOT rule out cancer syndrome
- Haplogroup resolution limited without WGS

## When to Recommend Genetic Counseling

- Any pathogenic hereditary cancer variant
- APOE ε4/ε4 genotype
- Multiple critical pharmacogenomic findings
- Carrier status with reproduction implications
- High-risk autoimmune HLA types with symptoms
- Results causing significant user distress
