1. Scope
This policy applies to all matters relating to credit spending and credit purchases within the tile interior rendering service provided by LibsTool (“we”, “us”). By purchasing credits, you confirm that you have read and accept this policy.
Where this policy conflicts with the Terms of Service, this policy prevails on matters concerning credits and payments.
2. How credits are charged
When you start a render or an AI tile analysis, we reserve the credits shown on the page at that time. Credits are deducted only when the job finishes, and any reserved credits that are not deducted are returned to your available balance immediately.
A single render may request several candidate images, and the price is per image. If only some of the images are generated successfully, we charge only for the images that succeed and return the remainder proportionally. For example, if you request 4 images and 1 succeeds, only 1 image is charged.
If no image is generated, the reserved credits are returned in full. “Generated successfully” means an image you can open and download from your history; if the system reports success but no usable image is produced, it is treated as unsuccessful.
AI tile analysis is a one-off charge, priced before you start, and is charged once the analysis completes.
Rescoring that we initiate because we have adjusted the style catalogue does not consume your credits.
3. Credit validity
Credits, whether purchased or granted, have no expiry date and will not be voided or cleared due to inactivity.
4. Granted credits
Credits granted on sign-up, through promotions or as a bonus with a credit pack are granted credits. Granted credits cannot be exchanged for cash and are non-refundable.
Granted credits are used before purchased credits, so that as much as possible of what you paid for remains in your account.
5. Refunds after a purchase
Once a credit purchase is complete, it cannot be refunded, including any unused credits. Credits are a virtual good delivered instantly and usable immediately; delivery is complete once the credits are added to your account. Please make sure the pack you choose meets your needs before purchasing.
If, due to an error on our part, your payment succeeded but the credits were not added, please contact us: we will add the missing credits, or you may request a refund of that payment. Such cases are determined by the payment platform's transaction records.
When we agree to a refund, we reverse the credits issued for that order in proportion to the refunded amount relative to the amount actually paid; a partial refund reverses a proportional share. If your balance becomes negative as a result, the negative balance must be cleared before you can continue using the service.
6. Cases not eligible for a refund
Dissatisfaction with a render is not grounds for a refund. A render is a creative result generated from the style, room type and tile parameters you choose, and variation between renders is normal. Once an image has been generated and can be opened, the service is considered delivered; we do not return credits or money, or offer other compensation, on grounds of personal taste, unmet expectations or a wish to try another style.
AI analysis results that differ from your own judgement are likewise not refundable. The pattern, lightness, warmth and other labels produced by the AI analysis are initial values that you can edit on the tile's detail page free of charge.
Refunds are also not available where you deleted the tile or render record yourself and can no longer view it; where the image you supplied did not meet the requirements (format, size or content) and the render was affected as a result; or where your service was suspended for violating the Terms of Service.
7. Contact us
If you have a question about a charge, please first check the credit history in your account, which records every deduction and return. If your question remains unresolved, email contact@libstool.com with the relevant order number or job ID. We will reply within 7 working days.
Approved refunds are returned via the original payment method; processing times depend on the payment provider and are usually 1 to 15 working days.
8. Changes to this policy
We may revise this policy. A revised policy takes effect on the date it is published on this page and applies to purchases and spending after that date. Credits purchased before publication remain subject to the refund terms of the version in force at the time of purchase.
