Why aren't entries in the GitHub repository database changing?

Question

SQLite

Wrote a small bot along with a database in SQLITE 3 , id, username, first_name, last_name , registration date and last use date are entered into the database. On pycharm, everything worked, all entries were made correctly. But as soon as I uploaded the project to Heroku via the GitHub repository, the changes stopped being made. That is, my database (users.db) remained the same as it was with a couple of records, although in fact there should have been changes
