No account, nothing stored.
Direct on your calendar or your alarms.
No account, no lock-in, no sky drawn from a template. What you pay for is a real computation you can check against the ephemeris yourself.
Every position, sunrise, phase and season turn is read from a DE441 ephemeris — the same one observatories use — and printed exactly.
Read the live sky over your own spot free, and download a real sample of any book — you know exactly what lands before you pay a cent.
Buy, download, done. We don't keep your location, and there's no login to forget.
Print-ready files land the moment you check out. Live calendars land straight in your phone.
