No! When we make a project all content is owned by the client and open for them to access. You have all the usernames and passwords so at any time you can edit your own site or move it should you move on from CircuitBloom.
This being said, we DO offer a hefty discount and limited free maintenance hours to clients that allow us exclusive access to the project, as it allows for easier maintenance on said project. This discount can be bought out of at any time. Ask us about this in your free consultation.
