We are trying to change TAC Lite module a bit because some behavior doesn't fit us.
We have the same problem like on this post http://drupal.org/node/197656
And we cannot find where module keeps list of terms which user can view/update/delete.

Rather than create any new tables, it stores the schemes in drupal's variables table.

I realize this is more than a year after the fact, but I had to figure this out myself recently. TAC lite is using the users table and the taxonomy tables.

It creates vocabularies and terms in the tables built by taxonomy (vocabulary, vocabulary_node_types, term_data, etc) .

It stores the role based taxonomy permissions in the variable table.

The part that you are probably wondering about is where are users associated to taxonomy terms. Those values are serialized as grant ids in the data field of the user table. You'll see your schema name as the array keyMore on Grant Ids here.
