• 100 hours of Active time per month, affecting non-primary branch compute usage only. Active time on all computes is counted toward the limit, but when the limit is exceeded, only non-primary branch computes are subject to suspension. Your primary branch compute always remains available regardless of the limit, ensuring that access to data on your primary branch is never interrupted. You can monitor Active time on the Usage widget on the Neon Dashboard. The Active time limit resets at the beginning of each month. For instance, if you enroll in the Neon Free Tier in the middle of the month, say on January 15th, your Active time limit will reset on February 1st, the first day of the following month.

• A point-in-time restore window of 7 days of reasonable usage.
