How to restore your backup data in your account

4 min readUpdated October 28, 2026

Get your data back by signing in to your account, after a reinstall or when data is missing.

If your data is missing, doesn't sync, or you are reinstalling the app, you can get it back by signing in to your account: Tunder then reloads your latest online backup.

Before you start, check that your data has been backed up. Until it is backed up online, it only exists on your device.

Before you start: check the backup

  1. Open the online backup

    In the app: Settings, General tab, then “Online backup”. “Up to date” means everything is backed up.

    • Last backup: the date is shown in “My account”. It tells you how far your data is safe.
    • Unsaved sales: if the app shows unsaved sales, back up before you continue.
  2. Run a backup

    Open Settings, “My account”, then tap “Back up”. Wait for the “Backup complete” message.

    • Free accounts: the backup is manual, limited to one every 30 days.
    • Premium: the backup can be automatic (“Activate automatic backup”).
    • If “Backup Failed” appears, contact support through the chat before going further.

Restore on the same device

  1. Open “My account”

    In the app: Settings, then “My account”.

  2. Tap “Sign out”

    Confirm with “Sign out”. Tunder requires a backup before you sign out; if it fails, check your internet connection.

  3. Sign back in with the same account

    Use the same email address (or the same Apple or Google account). Your latest online backup is then restored.

    • If your data doesn't appear right away, keep the app open and online for a few minutes.

Restore after deleting the app

  1. Back up first

    Back up in Settings, “My account”, and wait for “Backup complete”. Without this backup, deleting the app can lose your data.

  2. Sign out

    In Settings, “My account”, tap “Sign out”.

  3. Delete then reinstall the app

    Delete the app, then install the latest version from the App Store or Google Play.

  4. Sign back in with the same account

    Your backup reloads automatically after you sign in.

Warning. All your data is first on your device, until it is backed up online. Deleting the app without a backup can cause permanent loss.

Restore on another device

  1. Install Tunder on the new device

    Download the app from the App Store or Google Play.

  2. Sign in with the same account

    Use the same email address as on the old device.

  3. Wait a few minutes

    Stay online: your sales, catalog and settings sync automatically.

    • Do you often switch devices? Always back up in Settings, “My account”, before you switch.

The app crashes or opens on a green screen

Don't delete it right away if you need to recover recent data.

  1. Get a copy of your data

    If the app opens, download a copy of your data (Settings, “My account”, “Download my data”). If you have several devices, use another device signed in to the same account.

  2. Contact support before deleting

    If the app won't open, write to us through the chat before deleting it: in some cases, the data can still be recovered.

Frequently asked questions

How do I know my data is backed up?
In the app, Settings, General tab: the “Online backup” row shows “Up to date” when everything is backed up, or the number of unsaved sales. The date of the last backup is in “My account”.
How often can I back up?
A free account is limited to one backup every 30 days. With Premium, backups are unlimited and can be automatic.
I don't remember which email address is linked to my account. What do I do?
Contact support before signing out or deleting the app. In “My account”, the app shows the address of the account you are signed in with.
The app says “No backup. Contact support”. What do I do?
Write to us through the chat without deleting the app. Also download a copy of your data (Settings, “My account”, “Download my data”).
Does my data come back after a reinstall?
Yes, if you sign back in with the same account and an online backup exists. Without a backup, data that was only on the device is lost.
