Answer 1

Save the state in localStorage on unmount and repopulate on initial mount

constructor(props){
    super(props);
    const local = localStorage.getItem('state');
    if(local) {
       this.state =JSON.parse(local)
    } else {
          this.state ={
               value: 1,
               toggled: undefined
          };
          this.handleToggle = this.handleToggle.bind(this);
    }
}

handleToggle = (event,toggled,index) => {
    this.setState({toggled});
    if (toggled == true){
         ///sync the Calendar code////
    }else{
       /// un sync ////
}

componentWillUnmount() {
   localStorage.setItem('state', JSON.stringify(this.state));
}
