2. After installing, open it in your normal web browser at an address on your own network — no company account is needed.
3. Create your own login for it, which only you control.
4. Use it day to day for testing mobile apps to find mistakes before users do, from your phone or laptop, through the browser.
5. Everything it stores stays on YOUR machine, under your control — that is the whole point of this kind of tool.
