Design principles & privacy
Two ideas: charting and conversations stay on your device; accurate charts matter more than fluent prose.
Local-first
| Data | Location | Sent to Mystilink servers? |
|---|---|---|
| Profiles, sessions, charts | Project .mystilink/ | No |
| LLM API keys | Local settings | No |
| Usage audit | .mystilink/usage/ | No |
| Account, billing, activation | Mystilink cloud | Yes (required) |
| Installers & update checks | Distribution & release metadata | Yes (metadata) |
LLM requests go directly from your machine to the provider. See Privacy & local data and the privacy policy.
Deterministic charting
BaZi, Ziwei, astrology, etc. use local engines—reproducible, verifiable—not model guesses.
When the chart is uncertain, the Agent should inquire before a deep reading.
Two configuration layers
- Metaphysics theory — charting workflow.
- LLM — understanding, planning, writing.
See LLM architecture.
