Duration of auto-renewable at IAP

Question

How can I know about duration of auto-renewable subscription between purchase-date and expire-date.

For example, If user has purchased 1 month product by auto-renewable in 31 Jan, when is expire day? (28 Feb?…If leap year?)

Thank you.

Answer 1

See Auto-renewable subscriptions ： How long a month is？.

If you're still curious, you can confirm by checking the expires_date field, which is in the receipt field of the JSON object that holds the parsed information from the receipt (in the production, not sandbox, environment). More at:
