Unless your agreement says otherwise, ownership of the final, paid-for deliverables created specifically for you transfers to you once all fees for them are paid in full. Until then we grant you a limited licence to use them for review.
We keep ownership of our pre-existing tools, code libraries, components, templates and know-how, and of any general techniques we develop. Where those are part of your deliverables, you receive a non-exclusive, perpetual licence to use them as part of the delivered work. Open-source and third-party components remain under their own licences.
Unless you tell us otherwise in writing, we may describe the project in our portfolio and case studies, and show non-confidential screenshots. We will not disclose your confidential information.
