Our system upgrades your subscription to the next-highest plan if usage surpasses the plan's limit in any 30-day period. This setting (on by default) may be toggled on or off in Project Settings, but beware that if usage goes beyond the limit, translations will fail to serve for visitors to your website.
Deleting your project does NOT cancel a subscription! Please contact support.
