Frequently asked questions
Straight answers about privacy, price, accuracy, and how Undersky works.
Is Undersky private?
Yes. Undersky is private by design. There is no account, no tracking, and no advertising, and we never collect your information. Your birth details, charts, and readings stay on your phone. The App Store privacy label reads "Data Not Collected," because there is nothing for us to collect.
How much does Undersky cost? Is there a subscription?
There are no subscriptions. Your daily horoscope, your natal chart and its reading, and a first look at your year are free. Relationship readings are a small one-time purchase that is yours to keep. Precise forecasts, timed to the minute, are available when you want them for planning.
Does Undersky work offline?
Yes. Your chart is computed right on your phone, so Undersky works without a connection, and your information stays on your phone.
What astrology system does Undersky use? Is it accurate?
Undersky computes planetary positions with precise astronomy, checked against independent sources. Eclipses, retrogrades, and returns are calculated from the real sky. Undersky uses Western tropical astrology with a Whole Sign house default you can change, and the exact degrees are always available in Explore.
Does Undersky need an account or my email?
No. There is no sign-up, no login, and no email required. Every feature works without an account, because there is no account system at all.
Are the readings tailored to me?
Yes. Every reading is built from your exact chart, and from the person or relationship you are reading for, in your own language. Your information is never collected to do it; your details stay on your phone.
Can I use Undersky for my family and relationships?
Yes. Undersky is built for the people you love: partner, parent, child, sibling, friend, or coworker, each with its own lens. A parent and child reading never reads like a romantic match, and readings about children stay developmental. This is enforced by the app itself.
What languages does Undersky support?
Undersky is written, not machine-translated, in 26 languages, with astrology terms and cultural context adapted for each one. Reading your chart in your own language is part of the point.
What devices does Undersky run on?
Undersky runs on Android and on iPhone. It is available now on Google Play, and the iPhone version is on its way to the App Store. On older devices it still computes and shows your full chart.
Is astrology in Undersky for prediction or for reflection?
Undersky is for reflection and self-understanding, not fixed prediction. It names the sky honestly, including harder stretches, and leaves the decision about how to meet them to you. It does not tell you what will happen, and it does not deliver verdicts about people.
Where can I get Undersky?
Undersky is out now on Google Play. The iPhone version is finished and on its way to the App Store; the badge on the home page turns into a link the day it lands.
