Really cool, but here are a few improvements that I would make:
You can see private Pokémon, maybe make the information hidden. (not the listing)
I would rearrange the layout of the Pokémon information to make it a bit more readable, space out the categories a bit.
The link for trainers is broken (should be /users, links to /trainers)
You can bypass the private Pokémon downloading just by clicking on the sprite in the overall summary
If you don't want to spend money on a domain, try a free website host. A bunch of garbled up nonsense would not entice me to click it (not dot tk, they are terrible)
Also, when you are signing up, there are no ToS or Privacy Policies anywhere to be found.
If you are looking for inspration, there is a really good Pokémon file hosting service that I use called Porybox.
Best of luck with this.
