### Can I switch plans at any time? When will the change take effect?
Yes, you can switch anytime.
- **Upgrade:** Takes effect immediately after payment, but the billing cycle will not reset. It continues based on your original cycle. Upgrading only requires paying the price difference.
- **Downgrade:** Takes effect on the first day after your current billing cycle ends.

### Can I buy extra credits if I run out?
You can upgrade to a higher plan at any time on the Settings → Plans and credits page or the Pricing → Payment page to get more Credits, which will take effect immediately.

### Will my unused Credits be reset to zero?
Depending on the specific situation, unused Credits will be automatically carried over to the next billing cycle in the following cases (rollover is only for one month, not permanent):
- Unused Credits after an upgrade
- Extra bonus Credits granted by the system in addition to the daily fixed Credits (15) under special circumstances
- Credits earned from inviting new users
- Credits obtained through redemption codes

### Will downgrading/upgrading affect my data?
If downgrading/upgrading reduces your storage limit, you'll get a reminder to back up or delete files to prevent any impact on the normal use of Atoms.

### Are subscriptions auto-renewed?
Yes. Both Pro and Max plans renew automatically every month unless you downgrade before your next billing cycle starts.

### Can I cancel my subscription anytime?
Yes, you can downgrade your current plan to the Free plan at any time.

### Where can I check my plan and billing info?
You can view your current plan, Credits tier, remaining balance, and billing history anytime in the Settings → Plans and credits page or the Pricing → Payment page.

### What are credits and how are they used?
- Credits are points used to access services, including daily bonus credits, monthly subscription credits, and reward credits.
- The system automatically uses credits in this order: daily credits (15 per day) first, then subscription credits, and finally bonus credits.
