Recovery request for old deleted Backendless application – The Science of Winning

Data Service

Hello Backendless Support,

I am trying to recover data from an old Android application called The Science of Winning, originally published by F&G Partners.

Application ID: 25E0B0FB-A633-9969-FFEE-B09607EAAC00
The app now returns Backendless error 9000: “Application with ID … does not exist.”
I am trying to determine whether any historical backup of this application or its Exercise table still exists.

I am an end user of the original paid Android application, not its developer. I still have the genuine application installed on an old Android phone and have preserved the original signed APK.

The application details I have recovered are:

Application name: The Science of Winning
Application ID: 25E0B0FB-A633-9969-FFEE-B09607EAAC00
Android package: com.fgpartners.thescienceofwinning
App version: 1.1.9
Version code: 33
Approximate release date: 2017

The app previously worked normally and remembered the user’s login automatically. At some point it stopped signing in and began displaying a login screen.

The app now receives this response from Backendless:

{"code":9000,"message":"Application with ID 25E0B0FB-A633-9969-FFEE-B09607EAAC00 does not exist","errorData":{}}

I have independently tested the original application ID against the current Backendless North American and European API endpoints and receive the same error 9000 response.

The most important data appears to have been stored in a Backendless table named Exercise. The application contained a large library of swimming training workouts that is no longer otherwise accessible.

Could you please check your historical records and backups for this Application ID and let me know:

  1. Whether the Backendless application was deleted, archived, or migrated.
  2. Whether any historical backup of the application still exists.
  3. If a backup exists, whether it can be restored or whether the data from the Exercise table can be recovered/exported.
  4. What the cost would be for recovery, if there is a recovery fee.

I can provide the genuine signed APK, its SHA-256 hash, screenshots of the error, and additional technical information if required.

Thank you very much for checking.

Hello @phillip_cc

I have checked our system across our clusters for the Application ID you provided (25E0B0FB-A633-9969-FFEE-B09607EAAC00). Unfortunately, the application has been completely deleted from our system. Typically, when an app is deleted and purged like this, it means it was running on a free plan (often removed due to prolonged inactivity) or the developer explicitly closed their account.

To answer your specific questions:

  • Historical backups: We do not maintain or store historical backups for deleted applications that were on the free plan.
  • Data recovery: Because there is no backup available on our end, we cannot restore the application or export the data from the Exercise table.

Since you are an end user rather than the developer of the app, your best course of action would be to try and contact the original developers (F&G Partners) directly. They are the only ones who might have their own offline backups or the ability to re-deploy the application.

Regards,
Viktor
