what we keep, and what we never do.

moonth is the true calendar: an app for iphone and this website. both are made by Aletheia Studio LLC · 30 N Gould St, Ste N, Sheridan, WY 82801, USA. this page says what each of them keeps.

the moonth app

everything you give moonth stays on your phone: your birthday, your places, the people you add, your cycle if you use it, and what you keep. there is no account and no sign-in. the sky is worked out on the phone itself, so nothing you type is sent to us or to anyone else.

there are no ads, no tracking and no analytics in the app. if you turn on the daily note, it is scheduled on your phone. when you share a card or a link, you choose what goes and to whom. when the app asks you to rate it, the request is apple’s own and tells us nothing.

if you delete the app, everything it kept goes with it.

this website

the true sign and your moon are read from the sky inside your own browser. the day you type here is not sent to us.

this site keeps no email addresses and sets no cookies. it has no forms that send anything to us. if you arrive through a friend’s card, your browser remembers that friend’s short code, and nothing more.

we do not count visits or use analytics on this site. the server that hosts it (vercel) keeps the usual short logs of requests to keep it running.

children

moonth is not made for children under 13 and does not knowingly collect anything from them.
