Delete Your Account
You can request deletion of your Early Warning System (EWS) account and associated personal data. This page explains how deletion works, what is removed, and what may be retained for public health and legal reasons.
1. How to request deletion
Choose one of the following options:
- Email request (recommended): Send an email from the address linked to your account to ews-support@rise-challenge.co.tz with the subject line Account deletion request. Include your full name and the phone number or email used to register.
- Through your administrator: If you are an institutional user (for example CHW, district, or regional staff), your District or Regional administrator may also process a deletion request on your behalf.
We may ask you to verify your identity (for example by confirming an OTP sent to your registered phone or email) before processing the request.
2. What happens after you request deletion
- We will acknowledge your request within 7 business days.
- Account deletion is typically completed within 30 days unless a longer period is required for legal or public health record obligations.
- Once deleted, you will no longer be able to sign in or receive personalized alerts through that account.
- You may register again later with a new account if the programme allows it.
3. Data that will be deleted or de-identified
When your account is deleted, we aim to remove or de-identify:
- Your user profile (name, contact details, role, institution, and preferences).
- Login credentials and active sessions.
- Personal chat conversation history linked to your account.
- Device-specific tokens used for notifications, where applicable.
4. Data that may be retained
Because EWS supports public health surveillance, some information may be retained even after account deletion, including:
- Health survey and surveillance submissions that have already been used for reporting, where retention is required by MoH, district health teams, or approved programme agreements. Where possible, these records are de-identified so they can no longer be linked to you personally.
- Aggregated analytics that do not identify individuals (for example district-level trend charts).
- Security and audit logs needed to investigate abuse, meet compliance requirements, or protect system integrity, retained for a limited period defined by programme policy.
- Backups that are overwritten on a rolling schedule; deleted data may persist in backups until those backups expire.
5. Unregistering without full deletion
The EWS SRS allows the general public to register or unregister from the system. If you only want to stop receiving alerts but keep an account for occasional use, contact support to adjust your notification preferences instead of deleting your account.
6. Questions
For privacy questions or to check the status of a deletion request, email ews-support@rise-challenge.co.tz.
