Click ⚡ Credits in the upper-right corner and open My Account. Under Plan & Usage > Current Plan, select Cancel Subscription and follow the prompts.

Your cancellation takes effect at the end of your current billing period. You'll continue to enjoy your subscription benefits until then. Afterward, your account will automatically switch to the Free plan, and your subscription won't renew.

We'll send a renewal reminder by email before your subscription expires. You can cancel your subscription at any time before it renews. Once canceled, you won't be charged for the next billing cycle. If a renewal charge is completed because the subscription wasn't canceled in time, we're unable to offer refunds under the User Agreement.

Annual plans purchased during anniversary campaigns or other limited-time promotions are promotional orders. Once the subscription is completed, membership benefits, Credits, and any applicable promotional gift eligibility are issued immediately. Unless required by applicable law, promotional purchases are not eligible for refunds. Please review the plan benefits, price, and subscription period carefully before purchasing.

You can earn Credits by:

• subscribing to a plan

Yes. Expiration rules depend on the type of Credits. Subscription Credits are valid during the current billing period. Credits purchased through Credit Packs do not expire. Promotional Credits follow the rules of the specific promotion and are usually valid for 3 to 6 months.
