Has Astrogoy been useful?
Astrogoy is an independent project, no ads, no external investment. If the tool has helped you, you can buy us a coffee. Each contribution funds servers, ephemeris files, and new features.
Buy a coffee on Ko-fiOne-time payment via Ko-fi. No obligation, no conditional reward — just voluntary support.
When will the PDF be available?
No concrete date. Development depends on closing the price, integrating LemonSqueezy, and defining the final 45-page structure. When ready, it will be announced on the home page and newsletter.
Will the web natal chart stop being free?
No. The web tool — calculation, wheel, basic interpretation, PNG export — is and will remain free. The PDF is an additional product for those who want a downloadable document with extended interpretation.
Why is the PDF not free?
Because the extended 45-page interpretation consumes paid AI per generation. The price covers per-generation cost and product development. The web tool, which has no marginal AI cost, remains free.
Can I use the web natal chart without an account?
Yes. No mandatory registration to calculate and view your chart. The account is only for saving charts between sessions, encrypted in Supabase.
Is Ko-fi the same as subscription?
No. Ko-fi is a one-time voluntary payment. No subscription, no recurring, no membership. If you want to support the project again in six months, you can; if not, no problem.
