Delete your account

This page explains how to request deletion of your Senmmar School account (com.sennmar.attendance, schoolmanger.com), and what happens to your data.

If you cannot sign in

Send an email to info@senmmar.com from the address associated with your account (or, if you do not have one on file, from any address you can be reached on) and include:

• The name of your school.
• Your role (teacher, student, parent, school administrator).
• Your username, student ID, or the phone number used to log in.
• Your full name as registered.

We will verify your identity through your school and then process the deletion. We may need to ask follow-up questions before we can act.

What gets deleted (students, teachers, parents)

As soon as you confirm deletion in the app, the following is removed from our active database:

• Your account record (username, password hash, full name, contact details).
• Your personal profile data and uploaded profile picture.
• Your group memberships and any RFID card binding (the physical card is unlinked from you).
• Your active sessions on all devices (you are signed out immediately).
• For students and parents: links between the parent and child are removed for the deleted account.

What gets deleted (school administrators)

School-administrator accounts created through the mobile Sign up screen can also be deleted in-app. Because a school administrator owns the school, the scope depends on whether other administrators exist:

• If you are the only administrator on your school, confirming deletion permanently removes the entire school and every piece of data attached to it: all students, teachers, parents, attendance, homework, grades, accounting, RFID bindings, devices, notifications, and audit history. This cannot be undone.
• If other administrators exist, confirming deletion removes only your administrator account. The school keeps running on the remaining administrators.

If you submitted the Sign up form but your school has not yet been approved, you can withdraw the pending signup request directly from the app — no account exists yet, and your submitted details (school name, contact information, password hash) are erased on withdrawal.

What may be retained

Some information may be retained for a limited period, for the reasons listed below. This is required to keep school records consistent and to meet legal and operational obligations:

• Backups. Encrypted backups may still contain your data until they are rotated out (typically within 30 days).
• School records. Your school may keep historical attendance, homework, grade, and accounting records for the periods required by local education and tax law. These belong to the school, not to Sennmar, and the school is the data controller for them.
• Audit and security logs. Minimal logs needed to detect abuse and to comply with legal obligations may be retained for a limited time.
• Aggregated/anonymised data that cannot be used to identify you may be retained indefinitely.

Timeline

• In-app deletions take effect immediately. Your active sessions on all devices are signed out at the same time.
• Email-based requests are actioned within a few business days, once we have verified your identity through your school.
• Backups are overwritten on the normal backup rotation.

After deletion

In-app deletion is permanent and cannot be undone. If you want to use the service again, ask your school administrator to create a new account for you.
