How can we help?
Write to us at support@cosmia.site. We read every message and reply as soon as we can.
When something looks wrong in the app, a screenshot and your device model help us find it faster. Please don’t include your birth details or journal entries in an email; we never need them.
Common questions
Which devices does Cosmia run on?
iPhone and iPad with iOS 26 or later. There is no Android or web version, and none is planned for the near future.
Do I need an account?
No. Cosmia has no accounts and no sign-up. Your birth details and journal are stored on your device and synced through your own iCloud when it is turned on.
Where do I enter or change my birth details?
In Profile, under Your data. Date, time and place are all optional; without a birth time you still get your Sun and Moon signs, and without any details the theme of the day works as it is.
How do I delete my data?
In Profile, under Your data, Delete all data removes everything you wrote and saved from the device and from your iCloud. Deleting the app also removes its data from the device.
How do I manage or cancel the subscription?
Subscriptions are handled by the App Store. Open Settings on your device, tap your name, then Subscriptions, and choose Cosmia. Cancelling keeps the subscription active until the end of the paid period.
The morning notification does not arrive. What can I check?
Open Profile in Cosmia and check that the Daily Reminder is on and the time is right. Then check Settings on your device: Notifications, Cosmia, Allow Notifications. Focus modes and scheduled summaries can also hold notifications back.
Why does Cosmia show a different Moon phase than another app?
Cosmia names one phase for the whole calendar day in your time zone, with the four main phases on the days of their exact moment. Apps that switch phases at the exact minute can show a different name near the boundary. The illustration also mirrors the lit side for the Southern Hemisphere.
Privacy and terms
The Privacy Policy explains what stays on your device and what the app sends, and how to delete your data. The Terms of Use cover the subscription, the free trial and what Cosmia is and is not.
