Practice log
Whatever you practise, mark it done. Nothing here goes on any scoreboard. It is backed up under your own recovery code so a season of times survives a new phone, and only that code can open it.

Your swimming ladder
Set your group once, and every time you log a race the next target updates.
Height and weight
Add it whenever you get measured — once a month is plenty. This is kept only for you, so a time can be read next to the body that swam it. Nothing is calculated from these numbers and nothing is judged.
Either one on its own is fine.
Best times
Your fastest recorded time for each event, kept separate for each pool length. Your full timing history stays here season after season.
