Delete Users

This guide will go over how to delete user records in bulk from OneSignal. If you want to delete segments without the user records see Deleting Segments.

If you would like to delete users from our API, see the API Delete Device Call. Currently you can only delete individual user records from the API.

Note: We may delete users in apps that we deem as being “inactive,” in-line with our Data Access and Retention Policy located in the OneSignal Privacy Policy

🚧

Deleting users cannot be reversed!

Once you delete users, there is no way to get them back. Deleted users can only get push again once they:

• Web: Clear browser cookies, then return to your site
• Mobile: Open the app again. We recommend being up to date on the latest version of OneSignal's SDK in the app.

❗️

WARNING: DO NOT DELETE ALL USERS

Be very careful when following these steps, make sure you do not delete all users.

Delete Bulk Users From the OneSignal Dashboard

Create Your Segment

See Segments for details on creating segments. We recommend using the "Last Session" filter with greater than 4320 hours (6 months). Make sure to select greater than and NOT "less than".

Before deletion, we also recommend sending 2 notifications to this segment to try winning those users back.

When ready, select the 3-dot Options button > View Users

In Audience > All Users

1. Check that the correct Segment is selected.
2. Select the arrow next to 'Update/Import Users' to reveal the dropdown
3. Select Delete Users In Segment

A confirmation screen will appear showing how many users will be deleted and require you to input the name of the segment to confirm deletion.

❗️

WARNING: POINT OF NO RETURN!

Once you press Delete Users this cannot be undone. Your users will be deleted.

After clicking Delete Users a confirmation screen will appear and you will be sent an email confirming the deletion.

You cannot delete more than 1 segment at a time per app.

Deletion of devices cannot be undone

Once you delete a device, you cannot get the device record back unless the device:

• Clears browser cookies, then return to your site
• Uninstall the app and re-install the app.
