Formulus — Account and data deletion

App name: Formulus
Developer: Open Data Ensemble
Package name: org.opendataensemble.formulus
Last updated: 4 June 2026

This page explains how users can delete their data and, where applicable, accounts related to Formulus. It is provided for Google Play and for end-user transparency.

Important: who operates your account

Formulus does not create or host end-user accounts on Open Data Ensemble servers. You sign in with a username and password for a Synkronus server that your organization (or project) operates. Account creation and server-side deletion are managed by that server administrator, not by the Formulus app alone.

1. Delete data on your device (local data)

You can remove data stored on your phone or tablet without contacting ODE:

  1. Uninstall Formulus from your device, or
  2. Open Android Settings → Apps → Formulus → Storage → Clear storage (wording may vary by device).

What is deleted: app settings, cached forms, local observations, attachments, and stored login credentials on that device.

What is not deleted: data already synchronized to your Synkronus server (see section 2).

Retention: Local data is removed when you uninstall or clear storage. ODE does not retain copies on its own servers.

2. Delete your server account and synced data

To delete your login account and data on the sync server (observations, attachments, user record):

  1. Contact the administrator of the Synkronus server you use (your project lead, IT team, or organization that gave you credentials).
  2. Ask them to delete your user account and any data associated with it on that server, according to their policies.

Open Data Ensemble cannot delete accounts or server data on third-party or customer-operated Synkronus instances.

Retention: Determined by your server operator’s policies, not by ODE.

3. Request help from Open Data Ensemble

If you are unsure which server operator to contact, or you need general guidance about Formulus:

  • Email: [email protected]
  • Include: app name (Formulus), your organization or server URL (if known), and whether you need local deletion help or server account deletion.

ODE will respond with directions; we do not have access to delete your server-side account without your operator’s involvement.

4. Deleting some data without deleting your account

Formulus does not currently offer a single in-app control to delete all server-side data while keeping your login account. Partial deletion on the server (e.g. specific observations) is handled by your organization’s processes or server administration tools.

Local-only partial removal: clearing app storage (section 1) removes local copies but does not remove data already on the server.
