A one-off payment is linked to your account. After activation, add your own API key in Settings.
Provider charges are separate
The unlock does not include prepaid model usage. Generation and requested translations use your configured provider and its quota.
Desktop option
The desktop app is also available from the project's GitHub releases. Web account storage and local desktop storage are distinct.
Activate the account you use for research
Sign in with Google, open Settings and purchase the optional AI unlock on that account. After payment, return to Settings to connect your provider key. Quantitative reports, the screener, watchlist and simulated portfolio are available without activating AI. Older desktop licences use a separate recovery portal; a local desktop licence and web account storage are distinct flows.

Methodology, sources and authorship
Astro Trader is developed by Víctor Balcells. The stock model weights valuation (40%), quality and trend (30%), and timing (30%). Risk filters and data coverage accompany the result. Crypto and ETFs have their own models; exploratory cycles do not enter the fundamental stock score.
Market data comes from external providers, including Yahoo Finance; insider evidence links to SEC filings. Consult each report's dates, original sources and coverage: a missing observation is not a confirmed zero. AI text is generated commentary, not a statement written or verified by the author.
