Cosmik has no investors and no ad-tech empire — just ~$60/month of servers and data feeds. Pro subscribers keep the free version free for everyone else (and get the best of the sky in return). That's the whole business model.
Frequently asked questions
How much does Cosmik Pro cost?
Early-bird pricing is $1.99/month (50% off the regular $3.99) or $19.50/year — two months free. The early-bird rate is limited to the first 500 subscribers and stays yours for as long as you keep the subscription.
Can I cancel anytime?
Yes — one click, no questions, and you keep Pro until the end of the paid period. Payments run through Stripe; we never see your card.
Does the free version stay free?
Forever. The live 3D map, ISS passes, aurora forecasts and basic alerts are free with no login — Pro funds the servers so that stays true.
What does 'priority alerts' mean?
Pro alerts fire on the earliest data refresh — up to an hour before standard notifications for launch scrubs, pass reminders and aurora storm warnings. When a viewing window is short, that hour matters.
