The style, form, and content of such advertisements or promotions may be changed without specific notice to you.
We fulfill our obligations to advertisers in accordance with applicable laws. You should independently assess the truthfulness of advertising information and be responsible for your own judgment. Except as expressly provided by law, we shall not be liable for any loss or damage you suffer as a result of transactions based on such advertising information or content provided by the aforementioned advertisers. You further agree to prudently assess the truthfulness and reliability of advertising information appearing in the products or services we provide. Except as expressly provided by law, you shall be responsible for transactions entered into based on such advertising information.
Some of our products or services are provided on a fee basis. If you use fee-based products or services, please comply with the relevant provisions. We may modify or change the fee standards and methods for fee-based products or services as needed, and may begin charging for some previously free products or services. Before such modifications, changes, or commencement of charging, we will provide notice or announcement on the relevant product or service pages. If you do not agree with such modifications, changes, or paid content, you should cease using that product or service.
You represent and warrant that:

You own the User Content posted on or through our products or services, or have the right to grant the rights and licenses set forth in this Agreement;
The posting and use of your User Content on or through our products or services does not violate, misappropriate, or infringe upon any third party's rights, including but not limited to privacy rights, publicity rights, copyrights, trademark rights, or other intellectual property rights;
You agree to pay all royalties, fees, and other amounts owed in connection with the User Content posted on or through our products or services;
You have the legal right and capacity to enter into this Agreement at your own discretion;
If we receive a notice from a rights holder claiming that content you have sent or disseminated infringes upon their relevant rights, you agree that we may independently assess and take measures such as deleting, blocking, or disconnecting links to such content.

Our products or services contain content owned by or licensed to us (" Company Content "). Company Content is protected by copyright, trademark, patent, trade secret, and other laws. As between you and us, we own and retain all rights to Company Content and our products or services. You may not remove, alter, or obscure any copyright, trademark, service mark, or other proprietary rights notices incorporated in or accompanying Company Content. You may not reproduce, modify, adapt, perform, display, publish, distribute, transmit, broadcast, sell, license, or otherwise exploit Company Content, nor create derivative works based on Company Content.

In particular, you understand and agree that all materials provided by us (including but not limited to format styles, filters, stickers, watermarks, music, etc.) are solely for use in short videos captured or edited through our products or services and as components of such short videos. You may not separate the materials provided by us from the aforementioned short videos in any way or use such materials independently in any form. You understand and agree that short videos captured or edited using our products or services and the above materials may not be used for any commercial purposes.

The names, logos, and trademarks of our products and services are all trademarks of the Company. They may not be copied, imitated, or used in whole or in part without our prior written consent or authorization.

Additionally, we reserve the right to remove any User Content from our products or services for any reason, without prior notice. User Content deleted from our products or services may continue to be stored by us, for reasons including but not limited to compliance with certain legal obligations, but may not be retrievable without a valid court order. We therefore recommend that you back up your own User Content. In other words, we do not provide backup services, and you agree not to rely on our products or services for backup or storage of any User Content. We shall not be liable for any modification, suspension, or discontinuation of our products or services, or for any loss of User Content. You should be aware that the internet has security vulnerabilities and that submitting User Content or other information may not be secure.
You agree that we are not responsible for and do not endorse User Content posted on our products or services. We have no obligation to pre-screen, monitor, edit, or delete any User Content. If your User Content violates this Agreement, you may bear legal liability for such User Content.
Unless otherwise provided in the Privacy Policy for our products or services, as between you and us, any content is non-confidential and non-proprietary, and we shall have no liability for the use or disclosure thereof. You acknowledge and agree that your relationship with us is not a confidential, fiduciary, or other special relationship, and your decision to submit User Content does not place us in a position different from the general public, including circumstances arising from your User Content. We owe no duty of confidentiality regarding any of your User Content, and we shall not be liable for the use or disclosure of any User Content you provide.
It is our policy not to accept or consider any content, information, ideas, suggestions, or other materials unless specifically requested by us or in accordance with certain specific terms, conditions, or requirements. This is to avoid misunderstandings if your ideas are similar to those we have already developed or are independently developing. Accordingly, we will not accept unsolicited materials or ideas, and we will not be responsible for such unsolicited materials or ideas. Notwithstanding this policy, if you choose to send us content, information, ideas, suggestions, or other materials, you hereby agree that we may freely use such content, information, ideas, suggestions, or other materials for any purpose, including but not limited to the development and marketing of products and services, without liability or payment to you.

We respect the rights of others, and we expect you to do the same.
We may, but are not obligated to, provide tools to help you protect your intellectual property rights.
You understand and agree that if you are accused of infringement by others or you accuse others of infringement, we have the right to provide the relevant parties' identities, contact information, complaint-related content, and other necessary information to the other disputing party or relevant authorities in order to promptly resolve the complaint dispute and protect the lawful rights of others.
