I used pen & paper. Although each step in the solve was easy, those steps are hard to spot. I needed to make lots of annotations, and it is easy to make so many that it becomes a big unreadable mess.

The easiest way is to take a column or row, figure out what is needed for the first digit, do the same for the second digit, and then figure out what combinations are allowed. Sometimes there is a first digit that can only be combined with one of the second digits.
Try this. It should make it a little less messy.

Spoiler:
The placement of the second digits are the same as the first digits flipped diagonally. This means that I can look at just one of the digits with the added rule combinations of numbers and their mirrors cannot repeat. The obvious implication is that the main diagonal has to contain all 7 numbers, as otherwise a palindrome would repeat. Do other diagonals share this requirement? Actually, doesn't it look like all diagonals occur in the same order? By assuming this pattern is real and connecting diagonals to get a length of seven, I get the following solution:
0362514
5140362
3625140
1403625
6251403
4036251
2514036
This seems to satisfy all of the rules.

The spoiler is correct. That is why this is only a simple example. This puzzle is made from a self-orthogonal Latin square.
