Installation help

Common fixes before you contact us.

Data stays on your phone

Invoices, customers, and bills are saved on your phone — not in the cloud. Don't use Clear storage, Clear data, or uninstall until you've exported the PDFs and reports you need.

App won't install

  • Confirm Android 11 or newer in Settings → About phone
  • Free at least 50 MB storage
  • Clear Play Store cache, then retry

Crashes on first launch

  • Before any cleanup in Android settings, export important invoice PDFs and Pro report CSVs to email, your files app, or WhatsApp so you have copies outside the app.
  • Update PocketGST from Play Store
  • Restart your phone, then open PocketGST again
  • Don't use Clear storage, Clear data, or uninstall until you've exported the PDFs and reports you need.
  • If support asks you to clear cache only: Settings → Apps → PocketGST → Storage → Clear cache. Do not choose Clear storage or Clear data. Export invoice PDFs (and Pro CSV from reports) first if you are unsure.

Still stuck? Contact support with your device model and Android version — or browse the help center.
