• One person must not create multiple accounts to bypass usage or credit limits.
• We may suspend accounts that breach these terms or compromise platform security.

4. Plans, credits and limits

The service offers Basic, Plus, Pro and Enterprise plans. Each plan grants a credit allowance and a set of features and AI engines.

Credits are consumed by AI and Nexus Builder AI features and reset at the start of each billing cycle. Unused credits do not roll over and have no cash value.

Basic includes reduced limits, among them a maximum of four generated images per day and slower image-generation response times.

We may apply reasonable technical limits to prevent abuse and keep the service available.

5. Subscriptions, billing and renewal

• Payments are processed by Paddle, which acts as Merchant of Record and issues the invoice, including applicable taxes.
• Plans are purchased on a monthly or yearly cycle and renew automatically at the then-current price until cancelled.
• Paid monthly plans may include a trial period configured in Paddle; yearly plans include no trial.
• You can cancel any time in the Subscription section. Cancellation takes effect at the end of the paid period: access continues until the renewal date, after which the account moves automatically to Basic.
• If a payment fails the subscription may become past due and paid features may be suspended.
• Refunds are governed by the Refund Policy.
