EdTech Tools is a collection of browser-based classroom tools hosted at edtech-tools.web.app. This policy explains what information the tools process, where it is stored, and how you can manage or delete it.
1. Overview
The tools run in your browser. Apart from the live classroom features described below, there are no user accounts, no server-side database, no analytics, and no advertising. We do not sell, rent, or share personal information.
2. Information stored in your browser
Most tools save their data only in your browser's local storage under per-tool
keys (for example, edtechTools.draftPulse.v1). This can include
rosters, assignments, settings, saved worksheets, and other content you enter.
It is stored on the device and browser where you enter it, and it can be removed
at any time using each tool's "Clear data" control or by clearing your browser
storage.
3. Math Sprint Live classrooms
To run a live multiplayer game, Math Sprint Live uses anonymous Firebase Authentication and Google Cloud Firestore. Opening a room creates a 6-character code, and the following is synced between the teacher's and students' browsers: the room code, game configuration, student nicknames, scores, and connection status. Students are not asked to create accounts or provide names, emails, or other identifying details beyond the nickname they choose. Anyone who has the room code can join.
4. DraftPulse Google Drive sync (optional)
If you choose to connect Google Drive, DraftPulse requests read-only access to:
- list the Google Docs inside one folder you select
(
drive.metadata.readonly), and - read those documents so their word counts can be calculated
(
documents.readonly).
Document text is converted to a word count and then discarded. Only file names, file IDs, timestamps, and counts are stored, along with the folder link you provide. The Google access token is held in memory for the current tab and session only; it is never written to local storage, cookies, or the page. You can revoke access at any time from your Google account's third-party access settings.
5. Third-party services
The tools load resources and services from third parties, whose own privacy practices apply when those features are used:
- Google: Firebase Authentication, Cloud Firestore, Google Drive API, Google Docs API, Google Identity Services, and Google Fonts.
- Cloudflare cdnjs: Font Awesome, Papa Parse, and html2pdf libraries.
6. Data retention and deletion
- Browser tools: data remains in your browser until you clear it with the tool's controls or clear your browser storage.
- Math Sprint Live: the room closes automatically when the host's browser closes or navigates away, and the host can also close a room manually, which deletes the room and its roster from Firestore. A room abandoned during a network failure can be removed from the Firebase console.
- DraftPulse Drive: no document text is retained. Disconnecting removes the stored Drive mapping from the browser.
7. Children and schools
The tools are intended for use by teachers and school staff in an educational context. Teachers are responsible for obtaining any consent required by their school or district before students use the tools. We do not knowingly collect personal information directly from children.
8. Security
We rely on the security controls provided by Firebase and Google APIs and use least-privilege (read-only) access for Google Drive. Because scores are submitted from student browsers, the games are intended for classroom practice rather than high-stakes assessment.
9. Changes to this policy
We may update this policy from time to time. The "Last updated" date at the top reflects the latest revision.
