Ds light is a lifestyle app developed by TWOGATE INC for iPhone users. This free app offers premium membership options for users who are interested in accessing exclusive content such as videos and blogs. The premium membership is available at a monthly cost of $8 (tax included) or an annual cost of $88 (tax included).

Users can conveniently manage their premium membership through their iTunes account, with automatic renewal options available on a monthly or yearly basis. It is important to note that unless the automatic renewal is cancelled at least 24 hours before the end of the current period, the premium membership will be automatically renewed. However, users have the flexibility to stop the automatic renewal at any time, as long as it is done at least 24 hours before the end of the current period.

To check the status of the premium membership and to cancel it, users can visit the "App Store" app on their iPhone, click on the account icon in the top right corner, and navigate to the "Subscriptions" section. From there, they can view the next automatic renewal date and manage the renewal settings.

Please note that cancelling the premium membership for the current month is not available. The cancellation process will only take place after the contracted period ends.
