Changing phones? Save your Rumbly records before you go

Make the copy before removing the app

Rumbly stores fasting, meal, water, weight and profile records on your device. This version has no automatic cloud sync. Before reinstalling, clearing app data or changing phones, export a backup while you can still open your records.

Backup export and import are part of the free record tools. An exported file is a snapshot of the data at that moment. New records will not appear in an older copy, so make a fresh one when you need an up-to-date backup.

Export and check the saved file

In Profile, look for Export Data. The app prepares a JSON backup and opens your device's sharing options. Labels and available destinations may vary.

1. Choose a private location you can access after a reinstall or on your next device.
2. Finish saving the file in the chosen destination; opening the share sheet alone does not save a backup.
3. Find the saved file there and check that its date matches the copy you intended to keep.
4. Keep the original backup until you have checked the restored records.

Treat a backup as personal information

The file can contain fasting times, meals, water, weight and profile details. Choose its storage and sharing destination with that in mind. Avoid a public folder or a shared conversation unless you intend the people there to have access.

Local records are separate from optional usage analytics and crash diagnostics, which are off by default. RevenueCat and Apple or Google separately process purchase information for subscriptions. Local storage does not mean that every type of app information always stays on your phone.

Import replaces data; it does not merge it

Before importing into an app that already has records, export a fresh copy of its current data. In Profile, choose Import Data, read the replacement warning and continue only when you have the right backup. Select the JSON file when prompted. Import replaces existing records and backed-up settings rather than combining two histories.

After import, check several dates and your settings. If an error appears, read it, keep the original file and avoid deleting your remaining copies. If the app requests recovery of previous data, follow that recovery prompt before continuing; free device storage if the message identifies a space problem.
