After the trial month you are free to choose one of our plans or continue to use the free plan.
If you don't decide for one of our affordable plans, but choose the limited free plan, all your galleries created so far and all uploaded files will of course be preserved. If the uploaded files exceed the total amount of data or the number of galleries in the free plan however, all exceeding files and galleries can no longer be downloaded and accessed by third parties, such as your clients.
Of course, you can always switch to a Lite, Pro or Business plan to continue working without any restrictions.
