Can I turn off auto-renewal for my subscription?

Yes, this is possible for Gyazo Pro users.

Note: This is not available for Gyazo Teams users.

If you would like to stop future automatic renewals (charges) but continue using the service until your current contract period ends, please Unsubscribe from Gyazo Pro.

With Gyazo Pro, canceling your subscription does not immediately return you to the free plan. Even after you complete the cancellation process, you can continue to use Gyazo Pro features until the period you have already paid for (expiration date) ends.

Once the expiration date passes, billing will stop automatically, and your account will switch to the free plan.
