Frequently Asked Questions
Do credits expire?
Never! Once you purchase a credit pack, you can use those credits anytime - there's no expiration date or time limit.
Can I try before buying?
Yes! Sign in with Google and you'll see a preview of your processed file. You only need credits to download the final result.
How does this compare to subscriptions?
Unlike monthly subscriptions that charge you even if you don't use the service, you only pay for what you actually use. Perfect for occasional users who don't need unlimited access.
What if I need more credits?
You can purchase additional credit packs anytime. Your credits accumulate, so buying multiple packs adds to your total balance.
Is my payment secure?
Absolutely! All payments are processed securely through Stripe, one of the world's most trusted payment processors. We never see or store your credit card information.
What happens to my files?
Your privacy is our priority. Uploaded files are deleted immediately after processing. Your results are available for download for up to 1 hour and are deleted after you download them. Only you can access your processed files.
