You can pay for a Yandex.Music subscription for a month or year using the website, or using the app via the App Store, Google Play, or the Microsoft Store. Your subscription will renew automatically: in a month or year, the price for the following month or year will be deducted from your account.
To change your subscription period or payment method:
Wait until the period has ended.
Select a different period or payment method.
If you paid for a new subscription before the the previous one expired, the remaining days will be added to the end of your new subscription period.
Your monthly subscription ends on November 25. You cancelled it and paid for a new one on November 15 (ten days before your previous subscription ended). Your subscription will automatically continue through December 15. When you cancel your current subscription, all the app functions will continue to be available to you for another ten days.
