Downgrade (How to cancel the Premium Plan)

Langsmith works with the Stripe payment service. To manage your payments, go to Account settings from Help.

From Account settings, press [Change plan/payment method] to page to Stripe payment page, and press [Cancel plan] on Stripe payment page to cancel the Premium Plan.

Continued billing and plan changes for Premium Plan

Unless the user cancels the Premium Plan, the contract will be automatically renewed. If the user cancels the Premium Plan within the contract period, the contract will continue for the already billed subscription and be canceled at the end of the contract period. For example, if you sign up for a one-month plan and cancel the contract before the end of the contract period, you will continue using the Premium Plan features for one month.

Please note that it is impossible to change the price plan (1 month, 3 months, or 1 year) during the subscription period. If you want to change the plan, please cancel the continuous billing (downgrade) and sign up for another plan after the subscription period.

⚠️
Please check the Terms of Use and Privacy Policy carefully.
