PracticeEco method library
Free Purple Star chart vs paid report
What remains free, what the one-time report adds, and what payment never proves.
What the implementation can support
The free PracticeEco experience is intended to stand on its own: it draws the complete twelve-palace chart when time information supports one, names the deterministic public type, shows the self-report scores, compares the two structures, and creates a shareable public type link. A visitor does not need to pay to learn the result name or inspect the chart that produced it.
The paid report sells depth and packaging, not a hidden identity. It adds the fixed chapter structure, more cross-references, deterministic charts, reviewed explanatory blocks, bounded personalised reflection text, and downloadable HTML/PDF delivery. The launch product is one one-time purchase rather than a subscription, and private report access uses an opaque, expiring token.
Payment does not make the traditional chart scientifically valid, the self-report clinical, or agreement between them proof. Before buying, a visitor should be able to see the exact contents, a real sample, current price, delivery format, refund terms, privacy/erasure path, and known limits. If those facts are absent, wait rather than paying for a promise.
Use and limits
This page explains a rule, label, or product boundary. It is not a clinical instrument, a forecast, or a substitute for direct evidence about a person. Different Purple Star astrology schools can use different calendar and transformation choices.
