Effective Date: 1st of July 2025
Introduction
Gradifier is built with data minimization, transparency, and privacy by design. We aim to deliver a secure, seamless grading experience while respecting the confidentiality of both educators and students. This policy outlines how we manage information collected via the Gradifier extension and its related services.
Data Collection and Usage
a. Authentication and Access
We use Firebase Authentication to manage user accounts. During sign-up or login, we collect your:
- Email address
- Username
- Password
This data is used exclusively for identity verification and access control. We do not monitor, misuse, or share this information beyond what is required for login and account management.
b. Grading Context Data
When the extension is active, it reads content on Moodle pages visible to the user. This may include:
- Student names and IDs
- Assignment titles and questions
- Student responses
- Rubrics, model answers, and educator prompts
This information is only used to power grading and feedback features. It is:
- Not stored on our servers
- Not shared with third parties (except when sent securely to OpenAI APIs)
- Processed either locally or via encrypted API calls
Data Storage and Ownership
All grading data and educator-generated content (e.g. feedback, rubrics) belong solely to the user. We do not store any student submissions or educator content in external databases unless explicitly saved by the user.
We use Google Firestore to store:
- Minimal user profile data
- Extension usage preferences
- Non-sensitive configuration settings
All data stored is encrypted in transit and at rest.
You retain full ownership of your content. We do not sell, rent, or use your data in ways not explicitly described in this policy.
Usage Analytics
Gradifier collects anonymous, non-personal usage data to improve product performance. This may include:
- Feature usage frequency
- Extension performance metrics
- Error logs (excluding personal content)
No personal, student, or identifiable grading data is included. These analytics are:
- Used solely for product improvement
- Never shared with third parties
- Visible only to the Gradifier team or, optionally, the user
Third-Party Services
Gradifier integrates with the following trusted services:
a. OpenAI API
Used for automated feedback generation, rubric alignment, and grading support. Only essential, anonymized content (e.g., question text or model answer) is transmitted. No student names, IDs, or identifiers are included.
- OpenAI Privacy Policy: https://openai.com/privacy
b. Firebase by Google
Used for authentication and lightweight data storage.
- Firebase Privacy Policy: https://firebase.google.com/support/privacy
We ensure all communications with these services are encrypted and follow industry-standard security protocols.
Security Measures
We implement robust security measures including:
- Secure HTTPS communication
- OAuth-based authentication
- Local-first data handling
- Encrypted Firestore storage (when used)
Gradifier does not store sensitive grading or student data in any remote servers. All third-party API communication occurs over encrypted channels.
User Control and Transparency
You are in full control of your data:
- Grading data is never auto-uploaded or stored without your action
- No external account is required to use core grading features
- Usage analytics are optional and non-invasive
- You may request deletion of your profile-related data at any time
Host Permission Clarification
Gradifier requests host permissions only to detect and activate on supported Moodle pages. The extension injects its UI only when valid Moodle parameters are detected. No other websites are accessed or monitored.
Policy Updates
We may update this Privacy Policy to reflect changes in features or legal requirements. All updates will be:
- Communicated via the Chrome Web Store listing or extension UI
- Effective from the date of publication
We recommend reviewing this policy periodically. Continued use implies acceptance of any changes.
