Who Owns Seedance, Is It Chinese, and What Happens to Your Uploads

Seedance is owned by ByteDance. It is a family of AI video models built by ByteDance’s Seed research organisation. You don’t buy it as a standalone product; you reach it through ByteDance’s Dreamina app, through ByteDance’s BytePlus cloud API, or through third-party platforms that resell access. On “is Seedance Chinese”: ByteDance’s own company page says it was founded in 2012 by a team led by Yiming Zhang and Rubo Liang, and that its first flagship product was the news app Toutiao. The international Dreamina service, though, is contracted through Bytedance Pte. Ltd. in Singapore. What happens to your uploads is set separately by each channel’s privacy policy and terms, so this page quotes those clauses side by side, checked on 2026-09-27.

One thing this page will not do is rate Seedance “safe” or “unsafe”. Whether a data-handling clause is acceptable depends on what you plan to upload and what you care about, and that call belongs to you. Our job is to show you which company you’d actually be dealing with and quote exactly what its terms say, with a source and a date on every line.

Who Owns Seedance, and Who Makes It

The Seedance models are published on seed.bytedance.com, the site of ByteDance’s Seed organisation. On 2026-09-27 its homepage carried the tagline “Advancing the frontier of intelligence, in service of humanity” and led with the announcement “One-take Creation, Flexible Referencing: Introducing Seedance 2.5”. Under the heading “Explore AI products and services”, the same homepage says: “Discover AI-powered services and applications built on Seed models across diverse scenarios”. The products it lists there include Dreamina, Dola, BytePlus, Lark and CapCut. Our version timeline tracks which Seedance versions exist and when each one shipped.

So the answer to “who makes Seedance” is ByteDance’s Seed team, and the answer to “who owns Seedance” is ByteDance. No separate company called Seedance appears in any of the official terms we read: the consumer and API terms quoted below all name ByteDance or BytePlus entities.

What ByteDance’s own corporate page (bytedance.com/en/, read 2026-09-27) says about the company:

That last point matters more than the headline question. “ByteDance” is a group of separate legal companies, not one entity. The company you are actually contracting with changes from channel to channel, which is why the next two sections go by channel.

Is Seedance Chinese? What the Official Records Say

The question “is Seedance Chinese” usually means one of three things, and the records give a different answer to each.

Where the company comes from. ByteDance’s own history section says it was founded in 2012, launched Toutiao that August, launched Douyin in September 2016, and then “accelerated globalization with the launch of its global short video product, TikTok”. The same page separates its global products from “products and services specific to the China market”. ByteDance’s China-market AI assistant, Doubao, sits on doubao.com. When we checked that domain’s whois for our official-site-vs-clones guide on 2026-08-12, the registrant country was CN.

Which company you sign up with. For the international consumer product this is Bytedance Pte. Ltd. The Dreamina Terms of Service (last updated January 22, 2026) describe themselves as an agreement “between you and Bytedance Pte. Ltd., having its registered address at 1 Raffles Quay, #26-10, South Tower, Singapore 048583”. The Dreamina Privacy Policy (last updated April 30, 2026) says “The Platform is provided and controlled by Bytedance Pte. Ltd. with its registered address at 1 Raffles Quay, #26-10, South Tower, Singapore 048583”. For users in the European Economic Area it adds: “The data controller of your personal data is Bytedance Pte. Ltd.”

Where your data physically goes. That depends on the channel, and the policies name specific countries. The table in the next section lists them.

We are deliberately not turning these three answers into one yes/no. A reader worried about corporate origin, a reader who needs a named contracting entity, and a reader who needs to know which country their files are stored in are asking different questions, and each has its own documentary answer.

Which Company Handles Your Data Depends on the Channel

Seedance reaches users through several channels, each run by a different company under its own privacy policy. Our access guide covers what each channel gives you. This table covers who operates it and which document governs your data.

Once your upload reaches a third-party platform, that platform’s policy is the one that applies to you, whatever model it calls behind the scenes. Higgsfield’s policy, for example, lists among its service providers “third-party AI model and compute providers”.

What Happens to Your Uploads: the Clauses Side by Side

All quotations below were read on the live pages on 2026-09-27. Clause numbering and dates are the ones each page showed that day.

Dreamina

Dreamina is ByteDance’s own consumer route to Seedance, so its documents speak for ByteDance directly.

What it collects. Under “User Content” the Dreamina Privacy Policy says: “We may collect the content you create, import, upload, or generate through the Platform, including associated metadata (such as when, where, and by whom the content was created).” It goes on to say User Content “may include text, audio, and photos you upload and the prompts, files, and other types of information that you input or otherwise submit to our AI-powered interfaces, as well as the responses they generate”.

What it uses it for. Among its listed uses, the policy includes improving and developing the Platform, “including adding new features or capabilities including to train and improve our technology, such as our machine learning models and algorithms”. It also lists “scanning, analyzing, and reviewing User Content” both for product development and to enforce its Terms of Service.

Faces and bodies in your uploads. Under “Content Characteristics and Features”, the policy says it may identify “the existence and location of a face or other body parts” in videos, images and audio, and that “We do not use such information to identify you in your user Content.” It also says: “any face or body features or attributes extracted from videos, images, and audio will be deleted as soon as the requested Services are provided, and such extracted features or attributes will not be shared with any third parties.”

Where it goes. “We store the information we collect in secure servers located in the United States, Singapore, and Malaysia.” The policy also says entities in ByteDance’s corporate group “process Information You Provide, Automatically Collected Information, and Information From Other Sources as necessary to provide important functions such as storage, improvement and optimization of the Platform, security, research and development, analytics, customer and technical support, and content moderation.”

How long, and how to delete. “We retain information for as long as it is necessary to provide you with the Platform and for the other purposes set out in this Privacy Policy.” And: “The retention periods differ depending on the type of information and the purposes for which we use the information.” No single number of days is given in the main text. For deletion, the policy says: “You may submit a request to know, access, correct or delete the information we have collected from or about you”.

Who owns the output, and what licence you grant. Section 7 of the Dreamina Terms of Service (“Intellectual Property Rights”, under General Terms for all users) says that if you comply with the Terms, “you own the Inputs you upload, and the Outputs generated in response (together “Assets”).” The next sentence reads: “You grant us (and our affiliates, successors, and assigns) and other users of the Platform a perpetual, irrevocable, worldwide, non-exclusive, transferrable, no-charge, royalty-free, and sub-licensable, right and licence to use your Assets for any purpose.” Then: “This licence survives termination or expiry of our agreement with you for any reason.”

A note for US readers. The policy says: “For individuals in the United States, please refer to the Dreamina US Privacy Policy.” On 2026-09-27 the link behind that text pointed to dreamina.capcut.com/clause/dreamina-privacy-policy, which returned the same April 30, 2026 document to us. If you are in the US, open the policy while signed in to see which version your account is shown.

BytePlus ModelArk (the API route)

BytePlus is the enterprise route to Seedance. Its documentation lists “Resource packs for Dreamina Seedance 2.0 and 2.5 models”. Our API guide covers setup and billing. Its data terms describe BytePlus as a processor acting for a business customer, which is a different arrangement from a consumer app.

The “BytePlus ModelArk data processing” page (last updated September 10, 2026) says: “As a data processor, BytePlus ModelArk collects and processes Customer Data solely under customer instructions. Customer Data processing is located in Malaysia, Indonesia, and/or EU/EEA. Without the customer’s prior authorization, BytePlus ModelArk will neither interfere with the data processing nor use Customer Data for its own model training.”

On retention, under “Data retention and deletion”: “BytePlus ModelArk service may store your Customer Data for content safety purposes; input and output triggered by the filter are retained for 180 days in Malaysia.”

The words “prior authorization” point to a separate document. BytePlus’s Data Authorization Agreement (last updated May 21, 2025) says it applies to “the ModelArk Data Collaboration Rewards Campaign, and other campaigns”. A customer who opts in grants a licence to process “Authorized Data in connection with developing and improving the applicable Service, its underlying technologies, and BytePlus Parties’ machine-learning and artificial-intelligence technologies”. Clause 2.3 of that agreement covers withdrawing: “even after successfully completing the Opt-out Process, due to the nature of machine learning and artificial intelligence technologies, the data authorized to BytePlus Parties before you complete the Opt-out Process cannot be technically deleted.”

If you reach Seedance through an app that itself calls the BytePlus API, these are that app’s terms with BytePlus, not yours. Your relationship is governed by the app’s own privacy policy.

Higgsfield

Higgsfield is a US company that offers Seedance among other models. Our Higgsfield guide covers its credit pricing. Its privacy policy is effective August 27, 2026 and was last updated July 26, 2026.

Training. Clause 2.3 says Higgsfield may use personal information to improve the Service, “including by using your user-shared multimedia data, query and prompt data, and Inputs and Outputs (each as defined in our Terms of Use) to train and improve our (and our affiliates’) AI models and algorithms, and for content moderation and safety purposes”. It continues: “You can stop this going forward by deleting your content or account”.

Deletion. Clause 5.9: “Anything you remove from your account may remain on our active servers for 30 days, and copies of the content may be held in backups of our application databases after that.” After an account is deleted, “for thirty (30) days following deletion your account and content may be restored upon request.” On data already used for training: “Content already incorporated into our AI models before deletion cannot feasibly be removed from models that are already trained; going forward, we will not use deleted content to train our AI models, as described in our Terms of Use.”

Biometrics. “We do not store your biometric information. It is extracted and used only transiently, for the time needed to provide the feature you requested, and is destroyed as soon as that processing is complete”.

Location. “We are headquartered in the United States and may use service providers that operate in other countries. Your personal information may be transferred to the United States or other locations where privacy laws may not be as protective as those in your state, province, or country.”

Every other “Seedance” website

Many sites with “seedance” in the domain name are not run by ByteDance, and some don’t say who runs them at all. Our official-site-vs-clones guide went through them domain by domain. For data questions, the first check there does most of the work: find the legal entity named in the footer, terms or privacy page. If a site names no entity, you have no identifiable company to send a deletion request to. We did not review these sites’ privacy policies for this page.

Is Seedance Safe? The Questions the Clauses Answer

We don’t publish a safety verdict on Seedance or on any channel that offers it. “Safe” isn’t something a privacy policy can settle for you. It depends on whether you are uploading a stock landscape or a client’s unreleased footage, and whether training use, storage country or deletion timing is the thing you care about. What the documents above can settle is five factual questions. Here is where each channel answers them, so you can match them to your own situation:

1. Who is the company? Dreamina: Bytedance Pte. Ltd., Singapore. ModelArk: BytePlus. Higgsfield: Higgsfield, Inc., headquartered in the United States. Unknown sites: check the footer.
2. Can my uploads be used for model training? Dreamina lists training among its uses. ModelArk says no without prior authorization. Higgsfield lists training and says deleting content stops it going forward.
3. Which countries hold my data? Dreamina: United States, Singapore, Malaysia. ModelArk: Malaysia, Indonesia and/or the EU/EEA. Higgsfield: the United States or other locations.
4. How long after I delete? Dreamina gives no fixed number in its main text. ModelArk keeps filter-triggered content for 180 days. Higgsfield says 30 days on active servers, plus backups.
5. What rights do I grant over outputs? Dreamina’s terms say you own your Inputs and Outputs and grant Dreamina a perpetual, worldwide, royalty-free licence to use them “for any purpose”. For Higgsfield, read its Terms of Use (we quoted only its privacy policy).

Policies change. Each of the documents above shows its own “last updated” date at the top. Compare it with the dates on this page before relying on any quotation here.

Is Seedance 2.0 Legit?

Seedance 2.0 itself is a real ByteDance model, and three official sources confirm it independently. ByteDance Seed publishes Seedance model pages on seed.bytedance.com. ByteDance’s consumer app Dreamina carries the model. BytePlus’s ModelArk documentation lists “Resource packs for Dreamina Seedance 2.0 and 2.5 models”. There is also a 2.5 now: the Seed homepage was leading with “Introducing Seedance 2.5” on 2026-09-27.

“Is Seedance 2.0 legit” is usually a question about a specific website, though, not about the model. Selling access to a real model doesn’t make a site ByteDance’s. On 2026-08-12 we traced the operators behind the best-known “Seedance” domains in our official-site-vs-clones guide. One carried a footer saying it “is not affiliated with, endorsed by, or sponsored by ByteDance Seed or Seedance”. For free-access claims specifically, see Is Seedance 2.0 Free?.
