Privacy Policy

1. Who We Are

This application (“Riverside Sec Oral Conversation”) is operated by Riverside Secondary School, Singapore. It is designed to support English, Chinese and Malay oral language assessments for teachers and students.

2. Data We Collect

When you sign in with Google, we collect:

• Account information: your name and email address from your Google account.
• Audio recordings: recordings you submit as part of oral assessments.
• Assessment data: scores, feedback, and grading results generated during the assessment process.

3. How We Use Your Data

• To authenticate your identity and manage your account.
• To process and store audio recordings for oral assessments.
• To generate AI-assisted grading and feedback using Google Gemini and Anthropic Claude.
• To allow teachers to review student submissions and scores.

4. AI Processing

Audio recordings are processed by Google Gemini (transcription and delivery analysis) and Anthropic Claude (rubric-based grading) to provide assessment feedback and scores. Recordings are not used to train AI models.

If Google or Anthropic becomes unavailable to us, grading falls back to the same models reached through OpenRouter, a routing service. This happens rarely and only for as long as the interruption lasts. Requests are pinned to the original provider, so a recording is still processed by Google or Anthropic and never by a substitute model, and data collection by any intermediary is refused. Grades produced this way are labelled so a teacher can see which route was used.

5. Data Storage & Security

Your data is stored securely on Google Firebase and Cloudflare (cloud infrastructure). Audio recordings are stored on Cloudflare R2. Recordings and transcripts are sent to AI providers only to be processed. Google may hold a request in memory for up to 24 hours, and Anthropic deletes what it receives within 30 days, or up to two years if it is flagged under its usage policy. Neither uses this data to train its models. Access is restricted to authenticated users with valid @moe.edu.sg or @students.edu.sg email addresses. We implement appropriate technical measures to protect your data.

6. Data Sharing

We do not sell or share your personal data with third parties. Data is only shared with Google Gemini and Anthropic Claude for the purpose of AI-assisted grading as described above, and with OpenRouter (OpenRouter Inc, United States) acting only as a conduit to those same providers during a service interruption.

7. Data Retention

Riverside Secondary School keeps your child's oral practice recordings, transcripts, marks and feedback for the years they are with us, so that teachers and students can look back at progress. Work from each school year is deleted in February five years later, so a student who spends five years at the school keeps their whole history until they leave. Teachers can hide old assignments from view, but this does not delete them. Work a teacher deletes is removed from our systems six months later, and from our backups within fourteen weeks after that. You may ask the school to delete your child's data sooner.
