Every Zealder plan includes a monthly Zac credit allowance at no extra cost. These plan credits refresh at the start of each billing cycle, so you start each month with a fresh balance.

A few things to know about how the allowance works:

• Plan credits don't roll over. Any unused plan credits from the previous cycle are replaced by your new allowance — they don't stack up month to month.
• Bonus and purchased credits never expire. Only the monthly plan portion resets; trial/promo bonus credits and any packs you've bought stay on your balance until you use them.
• Higher plans include a larger allowance. If you regularly run low before your reset date, upgrading your plan is often the most cost-effective way to get more monthly credits.

Your balance panel under Account → Zac AI Credits shows your current allowance and the exact date your plan credits next reset. You can also ask Zac "when do my credits reset?"
