A separate log for each person · Poker Tracker devlog

Each person who signs in now gets their own log of poker sessions and their own lists of games and locations. One person can't see, edit or delete another's sessions, even knowing a session's id.
Export and import work on your own log only, so the same file can be loaded by two people without either overwriting the other.
A copy kept on one computer stays a single-person log with no sign-in. Logs from the first version move over on their own the first time the new version starts.
The hosted version checks every request's sign-in before serving anything, page or data, and refuses everything if the sign-in settings are missing.
