Hey there! No need to stress—canceling payments for your unused Heroku apps while keeping your account active for future use is totally straightforward. Here's a step-by-step breakdown tailored to your needs:

1. 取消单个应用的付费服务 #

You don't need to mess with your entire account—just target the apps you're no longer using:

• Log into your Heroku account and head to the Dashboard.
• Click on the app you want to stop paying for to open its details page.
• Switch to the Resources tab. Here you'll find two main types of paid services to adjust:
  • Paid dynos: Look for the "Dyno Type" section, click Change Dyno Type, then select the free tier (either "Free" or "Hobby Free" depending on your region). Confirm the change—this will stop charges for dyno usage.
  • Paid add-ons: Find any paid add-ons linked to the app, click Manage next to them, then choose Remove Add-on. Confirm the removal to cut off add-on charges.

2. 验证账单状态，确保无意外扣费 #

Double-check to make sure you won't get charged going forward:

• Navigate to your account settings and open the Billing page.
• Check the "Upcoming Charges" section—there should be no pending charges listed once you've adjusted all paid services.
• If you want extra peace of mind, you can remove your payment method from the "Payment Methods" section, but this isn't mandatory. Your account will stay free as long as no paid services are active.

3. 保留账户供未来使用 #

• Don't delete your Heroku account! As long as all your apps are on free tiers or have no active paid services, your account will remain in free mode. You can log back in anytime to spin up new apps or reactivate paid services.
• To prevent your account from being flagged for inactivity (though Heroku rarely deletes free accounts without notice), you can occasionally log in or deploy a tiny free app to keep it active.

A quick tip for later: When you're ready to use paid services again, just revisit the Resources tab for any app, upgrade the dyno type, or add a paid add-on—your account will pick back up seamlessly.
