Terms of Service

By downloading or using the Constella app, you agree to these terms. Please read them carefully before using the app.

Pentarab grants you a limited, non-transferable, non-exclusive license to use Constella on any Apple-branded device you own or control, in accordance with the Apple Media Services Terms and the Apple Standard EULA.

You may not copy, modify, reverse engineer, decompile, or extract source code from the app. All intellectual property rights belong to Pentarab. Constella embeds the open-source ssaju Saju engine (MIT licensed) for local Saju calculations.

Constella offers non-consumable one-time in-app purchases that unlock additional readings and features. The following terms apply to all in-app purchases:

• Price and the features unlocked are clearly displayed in the app before you confirm any purchase.
• Payment will be charged to your Apple ID account at confirmation of purchase.
• Purchases are billed once at the time of purchase with no automatic renewal.
• Purchases remain available across your devices and can be restored via the App Store on devices signed in to the same Apple ID.
• Purchases are eligible for Apple Family Sharing where supported.
• Refunds are handled by Apple in accordance with Apple’s refund policy.

All payments are processed by Apple through the App Store. Refund requests are handled by Apple in accordance with Apple's refund policy. Please contact Apple Support to request a refund.

Constella generates readings by combining Saju, Western astrology, and MBTI inputs. The readings are provided for self-reflection, entertainment, and personal insight only. They are not predictions, diagnoses, or professional advice. Constella does not claim to forecast the future or determine destiny.

You should not use the app as a substitute for medical, financial, legal, psychological, or any other professional advice. Decisions you make based on the readings are your own responsibility.

Constella is intended for users aged 13 and older. By using the app, you confirm that you meet this age requirement, or that a parent or legal guardian has consented to your use of the app.

You agree to use Constella only for lawful purposes and in a way that does not infringe the rights of, restrict, or inhibit anyone else's use of the app. You agree not to reverse engineer, redistribute, or commercially exploit any part of the app or its generated readings.

The app may require updates to continue functioning. You agree to accept updates when offered. We may modify or discontinue features at any time without prior notice.

Constella is provided on an "as is" and "as available" basis. Pentarab makes no warranties, express or implied, regarding the app's accuracy, reliability, or suitability for any particular purpose. Pentarab is not liable for any direct or indirect damages arising from your use of the app or reliance on the readings it produces.

We may update these Terms from time to time. Continued use of the app after changes constitutes acceptance of the updated Terms.
