Thank you for choosing Fastsub (the "Service", "Product", "We", "Us", or "Our"). We are committed to providing high-quality, privacy-first AI subtitle generation and translation services.
Because our Service provides an immediate digital quota (credits) and incurs irreversible third-party computing and artificial intelligence API costs (such as speech-to-text transcription and machine translation) upon use, we maintain a strict refund policy as outlined below.
By purchasing any credit packages or topping up your quota on Fastsub, you agree to be bound by the terms of this Refund Policy.
Free Trial Evaluation (Try Before You Buy)
To ensure our platform meets your workflow, hardware compatibility, and translation quality expectations, we offer a generous 30-minute free trial quota (30 credits) to all newly registered accounts.
- This trial version includes 100% of our premium features, including full 206-language translation and local video subtitle burn-in capabilities.
We highly encourage all users to fully utilize this free trial to evaluate the Service before making any financial commitment.
Strict No-Refund Policy for Used Credits
Once a paid credit package (including the Base Package at $9.90, the Plus Package at $39.90, or any custom pay-per-minute top-ups) has been successfully purchased and any portion of that purchased quota has been utilized by the user's account, the transaction becomes strictly non-refundable and non-cancelable.
We cannot issue refunds for used quotas due to:
- Dissatisfaction with AI translation accuracy or slight cultural mistranslations (which are inherent limitations of current automated language models).
Video rendering or burn-in failures caused by your local device’s hardware limitations, unsupported operating systems, or browser crashes (as video rendering is executed entirely utilizing client-side web browser hardware acceleration).
Unused credits remaining in your balance that you no longer need before the 1-year expiration date.
Conditions for Refund Eligibility
Refund requests will ONLY be evaluated and may be granted at our sole discretion under the following extremely limited circumstances:
-
Completely Unused Quota: You accidentally purchased a package and have NOT used a single second (0 credits consumed) of the newly purchased paid quota. The refund request must be submitted within fourteen (14) days of the original purchase timestamp.
Double-Billing Errors: Due to a technical glitch from our payment gateways, your account was charged twice for a single order. In this case, the duplicate payment will be fully refunded.
