Terms of Service

Lucky Calendar (“App”, “Service”) is operated by Lucky Corp., located in Ontario, Canada. Our contact email is lucky_calendar+support@pm.me. These Terms of Service (“Terms”) establish your and our rights and obligations under a legally binding agreement.

If you reside in the European Economic Area (EEA), the United Kingdom, or Switzerland (collectively, “EEA+”), please pay particular attention to the EEA+ specific provisions in Sections 7, 11, and 13.

By downloading, installing, or using the App, you agree to be bound by these Terms. If you disagree with any part of these Terms, you must not use the App.

1. Entertainment Purpose Disclaimer

IMPORTANT: Lucky Calendar is an ENTERTAINMENT application only.

All forecasts, predictions, “luck ratings”, probability calculations, and any other information provided by this App are generated for ENTERTAINMENT PURPOSES ONLY and have NO predictive validity whatsoever.

You expressly acknowledge and agree that:

• The “luck predictions” are based on mathematical algorithms using your historical input data and statistical patterns. They DO NOT and CANNOT predict actual future events.
• The App has NO scientific, mystical, astrological, psychological, or any other basis for predicting real-world outcomes.
• Any correlation between the App's predictions and actual events is purely coincidental.
• You will NOT rely on this App for making any decisions — financial, medical, legal, professional, personal, or otherwise.

2. Acceptance and Modification of Terms

By using the App, you agree to comply with these Terms. We may update these Terms from time to time. If we do, we will notify you of the changes by publishing updated Terms within the App. If you continue to use the App after the updated Terms are published, this means you have accepted them as of their effective date, unless applicable law requires that we obtain your consent in another way.

These Terms represent the entire agreement between you and us regarding the subject matter hereof and supersede all prior and current agreements, representations, and warranties regarding the App. If you breach these Terms, we may take action against you, including suspending or terminating your access to the App.

3. Privacy and Data

Such features may be offered as a separate subscription or add-on, or with usage limits.

New features and services:

• We may add new features and services to the App and decide whether each is included in existing plans, offered as a separate plan or add-on, or made available with reasonable usage limits.
• What you have already paid for stays yours: features included in your plan at the time of purchase will not be moved to a separate paid offer while your plan is active.

7. Payment and Refund Policy

All payments are processed by Google Play Store. We do not process payments directly and do not store your payment information. You are responsible for all charges made through your Google Play account.

For residents outside the EEA+: Payments are generally non-refundable except as required by applicable law or Google Play Store's refund policy.

For EEA+ residents: You have statutory rights under applicable consumer protection laws, including the right to withdraw from a digital content purchase within 14 days of purchase, unless you have explicitly consented to the immediate provision of the digital content and acknowledged that you thereby waive your right of withdrawal. To exercise your refund or withdrawal rights, we recommend using Google Play Store's refund process, which is typically the fastest method.
