Mammath.study (“we”, “us”, “our”) is committed to protecting the privacy of teachers and students who use our service (“the Service”). This Privacy Policy explains what information we collect, why we collect it, and how it is used.
By using the Service, you agree to the practices described in this Policy.
1. Information We Collect
1.1 Teacher Account Information
When a teacher creates an account, we collect:
- Email address
- Username
- Password (salted and hashed; never stored in plain text)
1.2 Class and Alias Information
Teachers may create:
- Class names (e.g., “7A”, “8-1”)
- Student aliases, limited to 3 characters
These aliases must not identify real individuals.
1.3 Assessment Data
Results for quizzes and activities are stored against aliases only. This data is available to the teacher for educational use until it is deleted by the teacher.
1.4 System Logs
For operational reasons, our hosting provider (Render) may temporarily record:
- IP addresses
- Browser or system metadata included in standard access logs
These logs are used for load management, debugging, and security. See Render’s logging documentation: https://render.com/docs/logging#log-limits
We do not access, export, or analyse these logs except when required for service integrity or security.
2. Information We Do Not Collect
We do not collect:
- Student names
- Student emails
- Dates of birth
- Personal identifiers
- Any information that directly links aliases to identifiable individuals
- Sensitive information
Students do not create accounts.
We do not use third-party analytics or advertising systems.
3. How We Use the Information
We use the information we collect only to:
- Provide login and authentication
- Deliver teaching, quiz, and reporting features
- Store and display alias-based results to teachers
- Maintain platform security and stability
- Communicate essential updates to teacher accounts
3.1 Aggregated, Anonymised Data
We may review aggregated, anonymised data (such as overall question performance statistics) to:
- Improve the quality, accuracy, and fairness of assessments
- Identify poorly performing or ambiguous questions
- Guide refinement of quizzes and curriculum materials
No individual teacher, class, alias, or school can be identified in this aggregated data.
We do not use any data for advertising, profiling, or commercial resale.
4. Cookies
We use only essential, first-party cookies:
- Session cookies for secure login
- Functional cookies to protect the “Contact Us” page and quiz pages by rate-limiting access (for example)
We do not use analytics cookies or third-party tracking cookies.
5. Data Sharing
We do not share any personal or class-level data with third parties. We have no external integrations, analytics platforms, or advertising partners.
6. Data Storage and Hosting
The Service is hosted by Render, using servers located in Singapore.
Data stored may include:
- Teacher account information
- Class names and aliases
- Alias-based assessment results
Render may temporarily retain server logs that include IP addresses (see Section 1.4).
7. Data Retention
- Teachers can delete classes, aliases, and results at any time.
- Deleted data may temporarily persist in system backups.
- Limits on active classes and quizzes discourage long-term data archiving.
- Stale data older than two years may be automatically purged.
- Teachers are encouraged to export required records for institutional storage.
8. Account Deletion
Teachers may request account deletion via the contact us page. When a request is received:
- The account will be permanently removed
- All associated classes, aliases, and results will also be deleted
- Backup copies (if present) will be removed automatically during normal archive cycling
9. Security
We implement reasonable technical and organisational measures, including:
- Secure hosting
- Password hashing and salting
- Restricted internal access
- System safeguards to prevent student identification
No online service can guarantee absolute security.
10. User Responsibility
Teachers must ensure that:
- The Service aligns with their institution’s privacy and data requirements
- Aliases do not identify students
- Required assessment records are exported for long-term retention
We can provide additional information to support institutional review if needed.
11. Changes to This Policy
We may update this Privacy Policy from time to time. Significant changes will be communicated via email to registered teacher accounts.
Continued use of the Service constitutes acceptance of updated terms.
