1. Introduction
These Terms of Use ("Terms") govern your use of the Shivaki app ("App") for iPhone, provided by Nader Grebe ("we", "our", or "us"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, please do not use the App.
2. The App
Shivaki is a yoga and stretching app that lets you build custom flows, follow guided sessions, and track your practice history. The App offers core functionality for free and additional features through an optional paid subscription called Shivaki Pro.
3. Shivaki Pro Subscription
3.1 Subscription Model
Shivaki Pro is offered as an auto-renewable monthly subscription. Once purchased, the subscription automatically renews at the end of each billing period unless cancelled at least 24 hours before the end of the current period.
3.2 Free Trial
New subscribers may be eligible for a 7-day free trial of Shivaki Pro. During the trial period, you have full access to all Pro features at no cost. If you do not cancel before the trial ends, the subscription will automatically convert into a paid auto-renewable monthly subscription, and the regular subscription fee will be charged to your Apple ID.
If you have already used a free trial for Shivaki Pro in the past, you may not be eligible for another one. Eligibility is determined by Apple.
3.3 Pricing and Payment
The current subscription price is displayed in the App before purchase. Payment is charged to your Apple ID account at confirmation of purchase and at the start of each renewal period. Prices may vary by country and are subject to change. Any price changes will be communicated in advance and will require your consent where legally required.
3.4 Auto-Renewal
Your subscription renews automatically at the same price and duration unless auto-renewal is turned off at least 24 hours before the end of the current period. Your Apple ID will be charged for renewal within 24 hours prior to the end of the current period.
3.5 Cancellation
You can cancel your subscription or manage auto-renewal at any time through your Apple ID account settings:
Settings → [Your Name] → Subscriptions → Shivaki
Cancellation takes effect at the end of the current billing period. You will continue to have access to Pro features until then. No partial refunds are issued for the unused portion of a subscription period, except where required by applicable law.
If you cancel during the 7-day free trial at least 24 hours before it ends, you will not be charged.
3.6 Refunds
All subscription purchases are processed by Apple. Refund requests are handled exclusively by Apple in accordance with Apple's refund policy. Please contact Apple Support at https://support.apple.com to request a refund.
