How to Export Your Data From the Zero Fasting App

Your fasting history is worth keeping. Years of completed fasts, weight entries, and streaks tell the story of real work, and none of it should be locked inside any single app. Zero lets you download a full copy of your data, but the process has a few non-obvious steps -- an email you have to wait for, a password, and a ZIP archive. This guide walks through all of it.

What you will need

The Zero app installed and signed in to your account
Access to the email address on that account
About five minutes

Step 1: Request the export inside Zero

Open Zero and go to your profile tab. Look for Download My Data (in recent versions it lives in the profile or settings area, sometimes under account or privacy options).

Tap it and confirm the request. Zero prepares the export on their servers, so nothing downloads immediately.

Step 2: Wait for the email

Within a few minutes (occasionally longer), an email arrives at the address on your Zero account. It contains two things:

A download link for your data
A password for the archive

Do not delete this email. The password in it is the only way to open the file you are about to download.

If the email does not arrive, check your spam folder first, then confirm which email address your Zero account actually uses -- exports go to the account email, not necessarily the one you expect.

Step 3: Download and unpack the ZIP

Tap the download link on your iPhone. Safari saves a ZIP archive to the Files app (usually in Downloads).

Open the Files app, tap the ZIP, and enter the password from the email when prompted. iOS unpacks it in place -- no extra apps needed.

Inside you will find your data as JSON files: your fasting sessions, weight history, and other account records. JSON is a plain machine-readable text format, which means any app or tool that supports importing can read it.

Step 4: Do something useful with it

A pile of JSON files is a backup, not a fasting tracker. Two common next steps:

Keep it as an archive. Store the unpacked folder in iCloud Drive or wherever you keep personal records. Your history is now yours regardless of what happens to any app or account.

Import it into another tracker. If you are moving to a different fasting app, look for one that accepts CSV or JSON imports so your streaks and history come with you. FastBreak, for example, imports Zero's export files directly: open Settings → Import fasting history, pick any JSON or CSV file from the unpacked archive, and your completed fasts appear in your history -- no account required, and the data stays on your device.

A note on owning your data

Whatever tracker you use, it is worth running an export once or twice a year. Apps get redesigned, accounts get locked, companies change direction. A local copy of your own history costs five minutes and removes the single point of failure.
