Does GPT forget the data after 30 Days sent on an API

I have a query that If I fine tune a model or do embeddings using my data in the database
Because fine tuning or embedding is also done using an API.
So the data which I feed using fine tuning will be erased from the model after 30 days ??

And also is it good to share the contents of database with the open ai
If not then how can I make chatbot which can answer questions based on the data in a database.
