Policy Overview
At Happyhorselab.net ("the Service"), we provide instant-access AI video generation through Happyhorse-1.0 — the #1-ranked model on the Artificial Analysis Video Arena, powered by the daVinci-MagiHuman architecture developed by Zhang Di's research team. This policy outlines our billing practices for AI video generation credits, credit pack rules, refund eligibility, service delivery terms, and fraud prevention measures to ensure transparency and a secure experience for all creators.

Happyhorse-1.0 operates on a credit-based model. When purchasing AI video generation credit packs, you must provide accurate and authorized payment information.

By purchasing credits, you authorize Happyhorse and our payment partners (Stripe) to charge your payment method for the one-time credit pack purchase. There are no recurring subscriptions — all credit packs are one-time purchases with specified validity periods.

Billing disputes must be reported within sixty (60) days. Pricing for AI video generation credit packs may be updated periodically, and changes will be communicated in advance through email or in-app notices.

Stripe processing fees are non-refundable under all circumstances, including refunded or canceled transactions.

You are responsible for any applicable taxes related to your credit purchases, and prices may vary based on region, currency conversion, or local regulations.

AI video generation credits are delivered instantly upon purchase and are valid for the period specified in your credit pack:

• Free Trial: 10 credits, 1 month validity
• Starter Pack: 240 credits, 1 month validity
• Professional Pack: 680 credits, 2 months validity
• Studio Pack: 2,800 credits, 3 months validity

Credits expire at the end of their validity period and cannot be extended or refunded after expiration.

Account sharing, automated scripts, or unauthorized API usage may result in account suspension without refund.

Credits are consumed based on generation complexity — features such as native 4K output, extended duration, MagiHuman human rendering, physics-accurate motion simulation, and batch processing consume more credits per generation.

Happyhorse-1.0 delivers AI video generation credits and functionality instantly upon purchase. For this reason, we offer a 30-day money-back guarantee to ensure your satisfaction with the platform and the daVinci-MagiHuman architecture.

We also provide free trial credits so you can evaluate Happyhorse-1.0 quality and features — including MagiHuman rendering, physics simulation, and 4K output — before purchasing a credit pack.

3.1 30-Day Money-Back Guarantee
If you're not satisfied with Happyhorse-1.0 for any reason — including generation quality, MagiHuman fidelity, physics accuracy, or feature set — you may request a full refund within 30 days of purchase.

To qualify for our money-back guarantee:

• Request must be made within 30 days of credit pack purchase
• Contact our support team at [email protected] with your purchase details
• No questions asked — we respect your evaluation period

3.2 Service Delivery
Once AI video generation credits are issued to your account or features are unlocked, the service is considered delivered and fulfilled, regardless of whether the credits are used.

Delivered credits remain eligible for refund under the 30-day money-back guarantee.

• Any dissatisfaction within 30 days (money-back guarantee)
• Duplicate payments (accidental repeat transactions)
• Confirmed unauthorized charges (after identity verification)
• Verified technical failures preventing access to Happyhorse-1.0 service

• Refund requests made after the 30-day guarantee period
• Stripe processing fees (non-refundable by Stripe)
• Content policy violations resulting in account suspension
• Proven fraudulent activity or abuse of systems
• Credits that have expired due to validity period completion

Refunds, when approved, are issued only to the original payment method. Processing times vary by bank (typically 5–10 business days).

Users should contact our support team at [email protected] before initiating a dispute with their bank. Filing a chargeback without attempting resolution may result in delayed processing or account restrictions.

Filing false or abusive refund requests may result in suspension, termination, or liability for related fees and losses.

If a dispute is filed after a refund has already been issued, the user may be responsible for any associated dispute fees charged by the payment processor.

Users who repeatedly initiate chargebacks against Happyhorse-1.0 credit purchases, or who misuse the dispute system, may have their accounts suspended or permanently banned from our Service.

We reserve the right to deny future service to accounts involved in chargeback abuse.

Given our 30-day money-back guarantee, we expect users to contact us directly for refunds rather than initiating chargebacks.

We maintain strict fraud prevention and security protocols for Happyhorse-1.0, including:

• Industry-standard security practices for all AI video generations
• User identity and payment verification
• Secure encryption through Stripe
• Machine-learning fraud detection systems
• Continuous monitoring and security enhancements

Accounts involved in fraudulent behavior — including stolen credit cards, unauthorized API access to the daVinci-MagiHuman model, or credit abuse — may be suspended or terminated immediately. We may report suspicious activity to relevant authorities.

Users must provide accurate information and comply with our Terms of Service and applicable laws when using Happyhorse-1.0.

This policy may be updated periodically to reflect changes in Happyhorse-1.0 features, credit systems, architecture releases, or legal requirements. Updates take effect immediately upon publication.

For questions regarding this policy or the 30-day money-back guarantee, please contact our support team at [email protected].

This policy operates alongside applicable consumer protection laws and does not limit your statutory rights.
