No, HeartMuLa offers one-time purchases only. Buy credits once and use them anytime. Credits accumulate across purchases - check your balance in the profile center.

No, your credits never expire. Once purchased, they remain in your HeartMuLa account permanently and can be used whenever you need to generate music.

Credits power all HeartMuLa AI features: Text-to-Music (create tracks from text prompts). Credit costs vary based on output length and complexity.

We accept all major credit cards including Visa, Mastercard, American Express, Discover, and JCB. Payments are securely processed through Stripe.

Standard music generation uses 10 credits per track. This gives you high-quality, studio-grade AI audio.

Please wait 1-2 minutes and refresh the page. If credits still don't appear, email us at support@heartmulaai.net with your payment receipt and we'll resolve it promptly.

Common causes: incorrect card details, insufficient funds, or bank security blocks. Try verifying your information, using a different card, or contacting your bank to authorize the transaction.
