3.5 The term “Licensed Content” refers to content that we have either licensed or own, which includes artwork, stock photos, audio, typefaces, videos, designs, and writings. Although you will retain sole and exclusive ownership of all rights, titles, and interests in your creative design project, any Licensed Content integrated into it is subject to the license outlined in Section 4 below. You are not granted any rights other than those specifically stated here. On the other hand, you give us an everlasting, non-revocable, global, non-exclusive, transferable, and sublicenses right and license to commercially utilize any feedback, suggestions, or recommendations that you offer to us in any way.
3.6 Provided that you continue to comply with the terms of this Agreement, which includes paying any associated fees promptly, we authorize you to use the Services for your internal business needs through a limited, non-exclusive, non-sublicensable, and non-transferable license.

4. Use of the Services:
4.1 You are allowed to use the Services for all projects and scope that fall within the parameters of your subscription plan and are appropriate based on the size of your account. Although we accept unlimited requests and revisions, the output volume is subject to several factors, such as the total number of requests and their complexity. While we will make every effort to work with you and prioritize your requests to meet your deadlines, we advise against using our Services for time-sensitive projects.
4.2 Although we strive to minimize errors, we cannot guarantee that all files delivered will be completely error-free due to the creative nature of design work and social media management. Upon receiving a file from us, you are responsible for reviewing and proofreading it for any errors or omissions. If any changes or corrections are required, you must notify us within seven (7) days of receipt. We will make every effort to edit quickly and correct any mistakes that you bring to our attention during this timeframe. However, if you report any errors after this period has elapsed, we are not obligated to but will make every effort to work with you to rectify any issues.
4.3 The speed of your account is determined by the number of subscriptions associated with your membership level. A subscription is a unit of measurement that represents the output achievable by our team, software, and web platform within a single business day. However, the amount of work that can be accomplished with a single subscription is subject to various factors, such as the type of plan, volume, and complexity of requests. Therefore, we cannot guarantee a specific amount of work that can be completed with a single subscription.
To enhance the volume of work that can be completed within a business day, we recommend adding more subscriptions to your account. This will allow us to increase the output achievable within a given time frame.
Some services are only available if paid membership is up to date.
4.4 You maintain full ownership and control of all information, data, or materials that you provide to us for the use of our Services (“Customer Content”). By submitting Customer Content to us, you warrant that you are the rightful owner of such Customer Content or have obtained the necessary rights, licenses, and authorizations to distribute it.
Additionally, you grant us a non-exclusive, worldwide, royalty-free license to access and use the Customer Content for the sole purpose of providing the Services to you. This license includes the right to reproduce, modify, distribute, display, and perform the Customer Content, as necessary to provide the Services.
This license will remain in effect during the term of your use of our Services and will automatically terminate upon the termination of your account.
4.5 You will have complete ownership over all deliverables and their associated intellectual property rights. This ownership extends to any and all rights, titles, and interests related to the deliverables, both now and in the future.
Any deliverables that may qualify as “work made for hire” under 17 U.S.C. §101 will be designated as such and will be considered your property. In the case that any deliverables do not qualify as “work made for hire,” we will assign all rights, titles, and interests, including any and all intellectual property rights, to you on a worldwide basis. This assignment is irrevocable, and you will have complete ownership over the deliverables and all associated intellectual property rights. Despite the preceding statement, the provisions of Section 4.5 are contingent upon your compliance with the terms of this Agreement, the payment of all applicable fees, and adherence to the terms set forth in Sections 4.6 and 5. You grant us a limited, non-exclusive, non-sublicensable, royalty-free worldwide license to utilize, host, operate, copy, reproduce, process, adapt, translate, publish, transmit, display, and distribute any deliverables that we produce as a part of the Services. This license is solely for the purpose of delivering the Services to you and managing your account. In addition, we reserve the right to use the deliverables and other information related to you and your use of our Services for internal purposes, with the objective of enhancing and improving our Services. This information may also be used in an aggregated form for marketing and advertising purposes, to demonstrate the range of our Services.
4.6 During the provision of Services, we may utilize specific pre-existing materials. Our licensors and we shall continue to be the sole and exclusive owners of all rights, titles, and interests in and to such pre-existing materials. We provide you with a perpetual, limited, royalty-free, non-transferable, non-sublicensable, worldwide license to utilize, display, and distribute any pre-existing materials to the extent necessary for the use of Services or deliverables. Such pre-existing materials may be incorporated in, combined with, or otherwise needed for the use of Services or deliverables.
All other rights in and to such pre-existing materials are explicitly reserved by us.
