Evernote

Evernote is an online file management platform where you can save all the information you need to keep in notes. Since your notes are synchronized on all devices you have access to, you can work from anywhere, enrich your document by adding various web pages and reminders to your notes.

With forms.app and Evernote integration, you can save your form responses by turning them into note documents. This will allow you to follow the data you obtain more closely.
