How information is used
Lockedscreen uses this information to:
- Let teachers connect their Google Classroom account.
- List teacher classes and assignments selected for exam setup.
- Export or connect an exam package to a selected class or assignment.
- Record student submissions and scores.
- Sync results to destinations configured by the school, such as Google Classroom or a school-controlled grade-sync endpoint.
- Enforce exam access rules, timing rules, start-code rules, and local secure-session controls.
- Help school administrators diagnose deployment and kiosk readiness.
Lockedscreen does not sell personal information.
Google API data use
When Google Classroom or Google Drive integration is enabled, Lockedscreen uses Google API access only for the classroom and exam workflows configured by the teacher or school administrator.
Lockedscreen may request Google API access to:
- Identify the signed-in teacher.
- Read the teacher's available Google Classroom classes.
- Read selected coursework, roster, or assignment information.
- Create or connect coursework where the teacher chooses to post an exam package.
- Access Google Drive files only where needed for the configured school workflow.
Lockedscreen does not use Google user data for advertising.
Lockedscreen does not sell Google user data.
Lockedscreen does not transfer Google user data to unrelated third parties.
Lockedscreen's use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Local storage and security
Lockedscreen is a desktop application. School configuration and exam data may be stored locally on the Windows device.
- OAuth tokens are intended to be stored using secure Windows storage rather than plain text files.
- Exam start codes are stored as salted hashes in exported packages, not as plain text codes.
- Schools are responsible for managing access to Windows devices where Lockedscreen is installed and for configuring appropriate administrator, invigilator, and kiosk controls.
Sharing of information
Lockedscreen may send exam or grade information only to destinations configured by the teacher or school administrator, such as:
- Google Classroom
- A school-managed grade-sync server
- A Google Apps Script web app configured by the school
- A Google Sheet destination configured through the school's sync process
Lockedscreen does not intentionally share student or teacher information with unrelated third parties.
Data retention
Data retention depends on the school configuration and the local Windows installation.
Schools can delete local application data, remove exam packages, clear Google tokens, disconnect integrations, or uninstall the application according to their own policies.
Google account access can also be revoked by the user through the user's Google Account permissions page.
Student and children's data
Lockedscreen may be used by schools for student exams.
Schools are responsible for obtaining any required notices, permissions, or consents under laws and policies that apply to their students and jurisdiction.
