How do I store dataentered in the app just on the device and not on appery cloud database?

I would like to have user enter some data in the app and leave it on that specific app instance on the local phone.

I understand that If user uninstalls the app, they lose all the data.

Hi,

You can use localStorage, websql, files for storing data.

Any pointers to know the details ?
e.g. where is the localStorage ? in phone memory ? Will not lose it after a restart ?
how to write to files ?

I used
localStorage.setItem('text', input);

but it somehow lost the data after a page move or restart.

Hi,

Did you test this in the browser or on the device?

Local storage is standard browser storage and API. Data you save will persist between navigation as well as closing/opening the browser.

It will get deleted if you clear the storage or over write a key/value.

You can use Chrome Dev. Tools to view current local storage content:

This Developer Tools is very helpful in debugging !
Thanks !

Q - if I have

if (!window.localStorage.mytext) {
window.localStoarge.setItem('mytext','HELP ! HELP !');
}
console.info('mytext:' + localStorage.mytext);

where to see the console.info output ?
