You can sideload the app yourself - but the account can only have 3 devices, and the app expires and stops running weekly for a free account or every 90 days (iirc - it's been awhile since I entered this particular dumpster fire) for a paid account. This is to prevent you as a developer from using your provisioning profile to backdoor-distribute software to end-users.

The largest loophole still is probably Enterprise Distribution, which allows high-limits (long time, many devices) signing associated with an Enterprise account.
