Data are lost after updating ionic app on App Store

I published my ionic application on App Store.

I am storing some data on the mobile phone with Ionic Storage

When I make new release/update on app store when the users update the application the data was lost?

Any idea?

I am using this library:

This is my part of code:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';
import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';
import { HttpClient, HttpClientModule } from '@angular/common/http';
import { IonicStorageModule } from "@ionic/storage-angular";
import * as CordovaSQLiteDriver from 'localforage-cordovasqlitedriver';
import { Drivers } from '@ionic/storage';
import { PrivacyConsentModalComponent } from './modals/privacy-consent-modal/privacy-consent-modal.component';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import {FormsModule} from "@angular/forms";

@NgModule({
  declarations: [AppComponent, PrivacyConsentModalComponent],
  imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule, HttpClientModule,
    IonicStorageModule.forRoot({
      name: 'mamaDb',
      driverOrder: [CordovaSQLiteDriver._driver, Drivers.IndexedDB, Drivers.LocalStorage]
    }),BrowserAnimationsModule,
    FormsModule],
  providers: [{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy }, Toast, ApiService, InternetService, SendMailService, ReadTxtFromFile],
  bootstrap: [AppComponent],
})
export class AppModule { }

Thank you
