Privacy overview
ClassStage is an independent project for teacher-led classroom lessons. This overview describes the public website and the current classroom app.
Visiting this website
The public website has no advertising, analytics scripts or account forms. Its balance demonstration runs in your browser and does not send or save answers. Hosting and DNS providers process the technical information needed to deliver and protect the website, such as IP addresses and web requests.
Using the classroom app
Teachers sign in with Google. ClassStage uses account identifiers and profile information to recognize approved teachers and apply their access permissions. The app stores lesson and classroom information needed for its features, including teacher resources, schedules, settings, pairing information and lesson progress.
The shared classroom board pairs with a teacher's session. It uses an anonymous technical account rather than requiring each child to sign in. Board interactions, including lesson actions and drawings, are synchronized with the teaching session. The current shared-board lesson does not require children to provide their names or email addresses.
Files and classroom content
Teachers may upload lesson files and create classroom content. Avoid putting student names, grades, photographs or other sensitive information into uploaded resources or drawings unless your school has approved that use. Teacher resources and room access are subject to the app's permissions.
Service providers and local storage
The classroom app uses Google Firebase for hosting, sign in, databases, file storage and server functions. Browser storage supports sign in and device preferences. Cloudflare provides this domain's DNS and, when enabled, routes incoming contact email. Operational logs and error reports may contain technical information used to run and troubleshoot the service.
Questions and removal requests
Contact ClassStage with questions about information associated with your account or to request removal. Please do not send student records or sensitive classroom information in your initial message.
hello@classstage.comSchool review
This overview is not a claim of school district approval or a data protection agreement. Schools should review the app, its access arrangements and their own requirements before classroom use. Specific retention commitments and school agreements should be confirmed before sharing student information.
