Terms of service

Last updated: 7 October 2026

These terms cover your use of Mosso's website, editor and library. Mosso is provided by the operator named in our legal notice. Contact: hello@mosso.video. By using the service, you agree to these terms. You can save or print this page for your records.

Free access

Mosso is free. A free account gives you access to the editor, saved account projects, templates, library downloads and exports. Every available export format is included, with no Mosso watermark. No payment card is needed, there is no recurring charge and using the free service does not sign you up for future charges. If we introduce an optional paid service, we will show its price and terms and ask you to agree before charging you.

Each account can request 50 library downloads a day, resetting at midnight UTC. Each download contains one item. Repeated requests count towards the limit. Library downloads through your account contain one animation per request. No bulk download button is provided. This daily limit applies to library downloads, not to exports of your own projects. Available formats and technical limits depend on the file and your browser. We show applicable limits in the service.

Your account

You must be at least 16 to make an account and able to enter this agreement under the rules that apply to you. Keep your sign-in details safe and give us an email address you can access. Tell us promptly if you think someone else has accessed your account. You are responsible for your own use, but not automatically for activity caused by our failure to keep the service secure.

You can use the local tools without an account. An account is needed for library downloads and cloud saving. Marketing consent is optional and is not a condition of free access. Our privacy policy explains how account data and optional usage events are handled.

Your content

You keep the rights you have in the content you upload and the original work you create. Using a library item or a third-party asset does not transfer ownership of that item to you. You give us a limited permission to store, copy and process your content only as needed to run the features you request, including syncing it and making it available to members of a shared space you choose. We do not acquire ownership of your work.

Only upload or use material you have permission to use, including images, fonts, logos and personal information. Check your exports before publishing them and keep a separate copy of work you need. This request to keep a backup does not remove our responsibility for a failure covered by law.

The library licence

You may download and edit Mosso library items and use them in your own projects and exports, including commercial work for clients. Mosso does not require a credit for its own work. Third party parts keep their own licences and any required credits. You may not resell or give away Mosso library items as standalone stock files, templates or packs, with or without small changes, or use the library to build a competing stock collection.

Some items include material under separate open-source or asset licences. Downloads include the source credits and licence notices. Keep these with the animation when you share it and follow the terms supplied with that material. For formats delivered in a zip, keep the credits file with the extracted animation. Those separate licences continue to apply, and these terms do not take away rights they grant you. Third-party photos have their own licence conditions; a photo licence does not necessarily clear rights in a person, logo or property shown in it. Check those rights for your intended use.

The free tools and exports

The Lottie tools process your files in your browser. Exports are created on your device. Keep your browser open until an export finishes. Your device, browser support and the input file affect which formats work. Any rights you have if a feature is faulty remain in place.

Acceptable use

Do not use Mosso for illegal content, harassment, fraud, malware or material that infringes another person's rights. Do not access another person's data without permission, bypass download limits, create accounts to evade those limits, scrape the whole library or deliberately disrupt the service. Security research and uses protected by mandatory law remain permitted within those legal rights.

Report illegal content, security concerns or misuse to hello@mosso.video with enough detail for us to investigate. Do not include someone else's private information unless it is needed to explain the issue.

Photos and your own AI

Photo search, when available, uses Unsplash or Pexels. Their licence and privacy terms apply to their services. Mosso's own AI is switched off during free access. If you connect your own AI, you use your separate account with its provider and pay any charges that provider sets. Check generated work for accuracy and rights before using it. These outside services do not remove our responsibility for the parts Mosso provides.

Existing shared spaces

If you already use a team space, its members can access its projects and brand kits. Content saved there stays with the team when you leave or delete your personal account. Your Personal space remains separate. Make sure you have authority to share material with a team. Account deletion details are in the privacy policy.

Your statutory consumer rights

Nothing in these terms limits statutory consumer rights. Where applicable law gives you rights to a service that works as described, necessary updates, correction of faults, a price reduction, a refund, withdrawal or termination, those rights still apply. A free service can be covered by consumer and data protection law. Contact us if the service is faulty so we can investigate and provide the remedy required by law.

Liability

We are responsible for losses caused by our breach of these terms or failure to use reasonable care and skill to the extent required by applicable law. For consumers, this includes reasonably foreseeable loss or damage. We do not exclude or limit liability for fraud, deliberate wrongdoing, gross negligence, death or personal injury caused by negligence, or any liability that cannot lawfully be limited.

There is no liability cap based on the price of this free service. We cannot guarantee uninterrupted access or compatibility with every device, but this does not exclude legal guarantees, remedies or our responsibility for service failures. Nothing in these terms requires you to waive rights or pay for claims that the law makes our responsibility.

Changes and availability

We may make changes for security, legal requirements, compatibility or service improvements. We will explain material changes to these terms or the service by email or an in-app notice before they take effect, with reasonable time to save your work and stop using the service. Urgent security or legal changes may need to take effect sooner; we will explain them as soon as reasonably possible.

Where the law requires advance notice on a durable medium, an explicit agreement or a right to end the agreement because of a change, we will provide it. We will not use a change to remove rights you have already acquired. If we close the service, we will give reasonable advance notice and an opportunity to export your content, unless the law prevents it.

Ending the agreement

You can stop using Mosso at any time and delete your account in Settings, Your data. Download anything you want to keep first. Your rights in law do not depend on using that button; you can also contact us.

We may restrict content or suspend or close an account for a serious or repeated breach of these terms, a security risk or a legal requirement. We will act proportionately, explain the reason and let you respond or correct the problem where appropriate. We may act immediately to prevent harm or comply with the law. Email us to ask a person to review a restriction. Where lawful and safe, we will allow you to retrieve your own content.

Complaints and disputes

Email hello@mosso.video if you have a complaint. These terms do not impose an exclusive court or mandatory arbitration. You keep the protection of mandatory consumer law and the right to bring a claim before a court that has jurisdiction under applicable law, including where you live when consumer law provides that right.
