Device transfer

Manual by design

Moving to a new phone?

4.2 is local-first. Your health data stays on your device and is not automatically transferred by Android backup. Moving it is a deliberate export and import — or an email to support.

Before you switch

Keep the old phone until the import works.

Do not uninstall the old app or erase the old phone until you have confirmed the data on the new phone. The app cannot restore data that no longer exists on a device.

Android cloud backup and device transfer exclude the app’s health database and photos. A normal phone migration will not move them.
Step 1

Email support

Send an email to support@weightasst.com with the subject “Data transfer”. Tell us the old phone, new phone, and what you want to move.

Step 2

Export the old data

If the old app is still available, export a JSON profile or full backup. Support can walk you through the right option.

Step 3

Import into 4.2

On the new phone, open the Privacy Center and choose Import data. Select the file and review the preview before importing.

Export & import guide

Before you switch

A five-minute checklist that saves the record.

The transfer is straightforward when you prepare. It is painful when the old phone is already gone.

  • Update the old phone to 4.2 first, if possible.
  • Export a JSON profile or full backup from the old phone.
  • Choose a password you will remember for a protected export.
  • Save the file somewhere you can access on the new phone.
  • Do not uninstall or erase the old phone until the import is confirmed.

What to include

Help us help you faster.

We do not need your full health file in the first email. Tell us the situation and we will ask for the right file or step.

  • Old phone model and Android version.
  • New phone model and Android version.
  • Is the old app still installed?
  • Do you have an export or backup file?
  • Do you use Pro? Which Google account?
  • What have you tried so far?
Privacy note. Only send a health export when support asks for it and through the method we recommend. Do not post your health file in a public review or forum.

Device transfer questions.

Does 4.2 sync automatically to a new phone?
No. 4.2 is local-first. Your health database and photos are excluded from Android cloud backup and device transfer. Moving to a new phone requires a manual export and import.
Can I export the data myself?
Yes. In the app, open the Privacy Center and choose Export data. CSV is weight history; JSON is the full profile. You can protect the JSON with a password. Then import it on the new phone.
Why does support need to be involved?
You do not need support for a standard export/import. Support is there if you are unsure which file to use, if the old app is no longer installed, or if the import does not work as expected.
Will my Pro purchase move too?
Your Google Play purchase is tied to the Google account used to buy it. Sign in with the same account on the new phone. If Pro is not recognized, email support.
Can you recover data I already lost?
Only if the data still exists somewhere we can access — an old device, an export, or a backup you saved. We cannot recover data that was never exported and no longer exists on a device.
