Predefined Offline database

Is it possible to create a pre defined offline database? It should be like an normal database with api or json but offline. So i can store data offline directly in this app while creating it and the app should be able to access this data. It’s for a quiz and i can’t / don’t want to pay for online database. (The app is also only for personal usage so there is no need for me only)

I hope you understand my english

Thanks

Locally storing records offline has been difficult for me. I would recommend using Xano as your database. It sounds like you will not need much storage for your project. Xano has a free tier that may meet your needs.
