Renderbuff

Terms of use

Last updated August 22, 2026.

These Terms of Use (the “Terms”) are a contract between you and the operator of Renderbuff (“we,” “us,” “our”). They apply to the website, studio, and related tools we provide (the “Service”). By creating an account, signing in, buying or using credits, or otherwise using the Service, you agree to these Terms and to our Privacy Policy and Cookies page. If you do not agree, do not use the Service.

If you use the Service for a company or other entity, you confirm you have authority to bind that entity, and “you” includes that entity.

1. The Service

Renderbuff is a private Seedance studio. You write a prompt, add optional pictures, video, or sound, and we send a job to a video provider. We try MachGen first. If that fails, we send the job to OpenRouter. Both run Seedance models. We may also send some jobs to Atlas Cloud. We add studio tools around that: a quote, a credit wallet, a gallery, and downloads.

This is a studio, not raw API access and not an unlimited plan. We do not give you our provider keys. We do not promise any particular model, price, speed, or uptime. We may add, change, replace, or remove models, resolutions, lengths, and features. A change of model is not a breach of these Terms.

Access may be invite-only or limited to listed emails. We may pause all new jobs, including with a kill switch, when our provider, our money, or the rules are at risk. We may cap how much we spend in a day. We do not cap how many of your jobs can run at the same time.

We grant you a limited, personal, non-exclusive, non-transferable, revocable right to use the Service for your own lawful work, as long as you follow these Terms. You may not resell the Service, share your login, or wrap our studio as if it were your own API.

2. Who may use it

You must be 18 or older, or the age of legal majority where you live if that is higher. The Service is not for children. By using it, you confirm you meet that age.

When we first open, only invited people or listed emails can join. We may require a confirmed email. We do not take new signups from places the law blocks, including sanctioned countries and named regions. You may not use the Service if you are prohibited under the laws that apply to you or to us.

One person or entity should keep one account unless we say otherwise.

3. Accounts

You must give a real email. We send a sign-in link to that inbox. There is no account password. Anyone who can open that inbox can use your account. You are responsible for all use of your account. Tell us if you think someone else used it. We may refuse, reclaim, or close an account.

You do not own the account. It is a right to use the Service. We may store an age confirmation and a record that you accepted these Terms.

4. Credits and money

Credits are not unlimited. You buy credits to run jobs on this site.

Credits are a prepaid right to use the Service. They are not cash, not a bank deposit, not a gift card, and not a stored-value instrument you can take elsewhere. They only work here. Unused credits cannot turn back into cash, except where a law forces us to give money back.

Credits last 180 days after we add them. We warn you before they expire, including 14 days and 3 days before, when our mail is set up. We spend the lots that expire first. When a lot expires, those credits are gone.

We convert dollars to credits with a working map: $129 is 3000 credits. That is not a hard promise for any one clip. The video provider sets each job quote, then we add 15 percent and round credits up. Packs may include extra free credits. The Generate button shows credits, not dollars. We store the wallet in cents and show you credits. We may change prices, packs, and the map going forward. A change does not alter credits already in your wallet, except that a job we already started still follows these credit rules.

When you press Generate, you spend the credits we showed you. If the job runs and the provider bills us, we keep those credits even if their bill was lower. If the job fails and the provider did not bill us, we refund those credits. Our ledger is the record of those changes.

If the provider finishes the clip and you just do not like it, we do not give the money back. If a job finishes and we cannot show the file because it breaks the safety rules, you still pay the credits we showed you. A review can unlock the file. A review does not refund those credits.

If a job fails in a normal way and the provider did not bill us, we refund those credits. If the provider billed us, we keep the credits we showed you.

Three blocked tries in a row are free when the provider did not bill us. The next blocked try costs 8 credits. A job we let through resets that streak. If a review says we were wrong about that block, we give those 8 credits back. A finished flagged job is never a freebie.

Card checkout may use a payment processor. That processor, not us, handles card numbers. You authorize the charge shown at checkout, plus tax if we must collect it. You are responsible for your tax obligations. If a charge is reversed or a chargeback is filed, we may suspend the account, cancel unused credits, and recover our costs.

Grants, test lots, and friend bonuses are credits too. They expire the same way unless we say otherwise when we add them. We can refuse or reverse a grant if it was a mistake or abuse.

If you are a consumer in the EEA or UK, you may have a 14-day right to withdraw from a purchase of unused digital services. Buying credits and asking us to run the studio is a request that we start. Once we add credits to your wallet or start a job, you lose that withdrawal right for that purchase to the extent the law allows. Unused credits that we have not started to provide may still be withdrawable where the law requires it. Contact admin@sanctivision.com.

Except as this section states or a law requires, all purchases are final. We do not give refunds for change of mind, unused time in a pack, or a clip you dislike after it finishes.

5. Jobs, quotes, and video providers

We only start a job after we have a real provider quote. MachGen quotes come from their public table. OpenRouter quotes come from their catalog. Atlas Cloud quotes come from their calculate endpoint. We do not invent a homemade price. A quote is not the final bill. We settle your wallet to our list price when we know they billed us.

We may refuse a job if the wallet cannot cover the spend, if we are paused, if our provider money or daily cap is too low, or if a check fails.

You can run as many jobs at the same time as you want. Credits still apply to each job. You may not open extra accounts to get around spend or safety limits.

We ask the provider for a last frame when we can. We do not put our watermark on the file. MachGen, OpenRouter, or a model vendor may still attach metadata. Asking for MOV or MP4 does not change what they charge us. A second job is a second bill.

Delete removes our copy when we can. We also try to cancel the matching job at the video provider. Cancel is not a promise. If the provider already billed, you still pay that bill.

6. Your content and outputs

“Inputs” are what you send us: prompts, pictures, video, sound, and settings. “Outputs” are the files we return, including video and last frames. Together they are your “Content.”

We do not claim ownership of your Inputs or Outputs. Between you and us, you keep the rights you already have in your Inputs, and you may use Outputs you lawfully receive, including for commercial work, as long as you follow these Terms and the law. We do not promise that an Output is unique, copyrightable, or free of third-party rights. Other people may get a similar clip.

You must have the right to upload the pictures, video, and audio you send us. If an Input shows a person, you must have the rights and consents needed to use that face, voice, or likeness for this purpose. Do not upload sexual fakes of real people.

You grant us a worldwide, royalty-free license to host, copy, process, transcode, transmit, and display your Content only as needed to run the Service: to check it, send it to MachGen or OpenRouter and our safety checker, store it, show it in your gallery, make playable copies, and support or review a job. We may sublicense that license to those providers for the same purpose. The license ends when the Content is deleted from the Service, except for short backups, legal holds, and records we must keep.

We do not use your private Content to train our own models. We do not have a public community feed. We will not use your private clips in our marketing unless you say we may.

MachGen, OpenRouter, Seedance, and other vendors have their own terms. Your use of Outputs must also follow those rules where they apply. We are not those companies.

You are solely responsible for how you use Outputs. Do not treat them as legal, medical, financial, or news advice. Do not present an Output as a real recording of a person if it is not.

If you send us ideas or feedback, we may use them without pay or credit.

We do not have to keep your files forever. We may set size, count, and time limits. If you want a copy, download it.

7. Safety and acceptable use

No explicit nudity or sex. No sexual content involving anyone 17 or under. No sexual fakes of real people. We'll check the prompt and references before we run a job. If we get it wrong, ask for a review.

Clothes, romance, and movie fights are okay. Explicit sex or nudity is not. Sexual content of anyone 17 or under is not, including when someone “looks young.” Sexual fakes of real people are not.

You also agree you will not, and will not help anyone else to:

We may refuse, hide, or delete Content, and we may report it to providers or authorities, when we believe these rules or the law require it. We do not have a duty to watch every job.

8. Checks, reviews, and hidden files

We check the words and pictures first. Only then you spend credits and we call the video provider. We use one no message. We do not name the checker in that message.

If our first checker is broken, we may still send the job to MachGen or OpenRouter. The provider may also refuse a job. If the provider stops a job for the same kind of content, we show the same no screen and they did not bill us. If the provider fails for a normal reason and they did not bill us, we refund those credits and we do not show the sex-rule screen.

If the provider finishes the video and flags it, they billed us. We hide the file for about 7 days. You pay the credits we showed you. If we later agree we were wrong, we show the file. We do not give those credits back.

You may have 1 open review. You may ask 3 times a week. A human looks. We try to answer in 24 hours. Review is a courtesy, not a right to a refund or a new job. We may deny review for CSAM, repeat abuse, or missing information.

9. Invites and friend bonus

You join with an invite link. You do not type a code. You may receive or create invite links when we offer them. You may not sell invites, guess links, or invite yourself.

A friend who invites someone can get 10 percent of that person’s first finished payment, in credits, not cash. We do not grant it just because someone signed up. We do not pay a chain of recruiters. We do not pay cash.

A referral cookie can remember a friend code. You can turn that cookie off. We may change, cap, delay, or end the bonus, and we may refuse it for fraud, self-dealing, or a reversed payment. Bonus credits expire like other credits.

10. Third parties

The Service depends on other companies. MachGen and OpenRouter run the models. A safety checker reviews prompts and reference files. Supabase keeps accounts and studio data. Cloudflare R2 stores files when those keys are set. Vercel hosts the site. We may use Resend for mail and a card processor when you pay. Each of them has its own terms and privacy rules. We are not responsible for their acts, outages, or policy changes, except that we settle your wallet as these Terms say.

Links to other sites are not an endorsement. Those sites are not part of the Service.

11. Our rights and notices

We and our licensors own the Service, the studio software, and our marks. These Terms do not sell you that.

If you believe Content on the Service infringes your copyright, send a notice to admin@sanctivision.com with: (a) your contact details; (b) the work you own; (c) the URL or job id of the material; (d) a statement that you have a good-faith belief the use is not allowed; (e) a statement that the notice is accurate and that you are the owner or their agent; and (f) your signature. We may remove material and close repeat accounts. This is a notice process, not a claim that we have a designated agent on file.

12. Suspension and closing

We may pause generation, limit features, refuse a job, or close an account if you break these Terms, if a payment fails or is reversed, if the law requires it, or if our video provider or our money is at risk. We may also close the Service.

You may ask us to close your account. We will stop new jobs and delete files we can delete, except records we must keep (for example the money ledger, safety reports, and legal holds). Unused credits are not cashed out.

If we close you for cause, unused credits are forfeited to the extent the law allows. If we shut the Service down for everyone and you have unused paid credits, we will try to refund the unused paid amount or give a fair substitute, except for grants and bonuses.

Sections that should survive do survive, including money, content licenses already used, disclaimers, limits on liability, indemnity, and disputes.

13. Disclaimers

The Service, quotes, Outputs, and third-party models are provided “as is” and “as available.” We do not warrant that a job will finish, that an Output will match your prompt, that files will stay online, or that the Service is free of errors. To the fullest extent the law allows, we disclaim implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

Artificial intelligence can be wrong, biased, or unexpected. You use it at your own risk.

14. Limits on our liability

To the fullest extent the law allows, we and our providers are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost data, or the cost of substitute services, even if we were told they were possible.

Our total liability for all claims arising out of the Service is limited to the amount you paid us for credits in the 180 days before the claim, or if you paid nothing, to fifty U.S. dollars. This cap applies in the aggregate, not per incident.

These limits do not apply to liability that the law does not let us limit, such as death or personal injury caused by our negligence where that bar is forbidden, or our fraud. They do apply to the fullest extent they can, including if a remedy fails its essential purpose.

Some places do not allow certain limits. In those places, our liability is limited to the maximum extent permitted.

15. Your indemnity

You will defend and indemnify us and our people from claims, damages, and costs (including reasonable legal fees) that arise from: your Content; your use of Outputs; your breach of these Terms; your violation of law or of someone else’s rights; or a chargeback you start without a good-faith basis. We may take over the defense. You will not settle a claim that binds us without our written consent.

16. Disputes

Before you file a claim, email admin@sanctivision.com and wait 30 days so we can try to fix it. Any dispute that remains must be brought only in your own name, not as a class, collective, or representative action, to the extent the law allows.

These Terms are governed by the laws of the jurisdiction of our principal place of business, without regard to conflict-of-law rules, except that if you are a consumer whose local law cannot be waived, those mandatory consumer rules still apply. Courts in that jurisdiction have exclusive venue, except that we may seek injunctive relief anywhere to stop misuse of the Service or our rights.

If a court will not enforce the class waiver as to a claim, that claim must proceed in court and the rest of this section still applies.

17. General

We may update these Terms. We will change the date at the top. If a change is material, we will try to tell you in the Service or by email. Continued use after the new date is acceptance. If you do not agree, stop using the Service.

These Terms are the whole agreement about the Service. They replace prior terms. If a part is unenforceable, the rest stays. A waiver once is not a waiver later. You may not assign these Terms. We may assign them in a sale or reorganization.

Force majeure: we are not liable for delay or failure caused by events beyond our reasonable control, including provider outages, law, war, and infrastructure failure.

Notices to us go to admin@sanctivision.com. Notices to you may go to your account email or a post in the Service.
