Effective date: 23 September 2026

Please read this before using Satit Chula Classroom Tools. It explains what the tool is, who may use it, and the rules for using it. If you are a student and anything here is unclear, ask a teacher or the contact at the bottom of this page.

1. What this is

Satit Chula Classroom Tools ("the Tool") is a Chrome extension that adds features to Google Classroom for โรงเรียนสาธิตจุฬาลงกรณ์มหาวิทยาลัย ฝ่ายมัธยม ("the School").

The School provides the Tool to its own community and decides how it is used and what data it holds.

Loxley Orbit develops the software and runs the servers and database behind it on the School's behalf, following the School's instructions.

The Tool is provided by the School as part of its own systems. It is not a commercial product, is not sold, and there is no charge to use it.

2. Who may use it

The Tool may be used by members of the School community — teachers, staff, and students — who sign in with a School Google account (@satitm.chula.ac.th). Anyone without a School account will be refused.

Because the Tool is used by students, some of whom are minors, students use it as part of the School's own educational activities and under the School's supervision, in the same way they use Google Classroom itself.

3. What the Tool does for different people

Not every feature is meant for everyone:

For everyone: the School branding in Classroom, the Announcements page, and a link to the School's teaching-evaluation site (T-Rating). T-Rating is a separate School system with its own sign-in and rules.

For teachers of a class: attendance recording, the workload indicator shown when creating an assignment, class tools (random student picker and group maker), and linking rubric criteria to the School's competencies. Attendance and competency records are official School records, and only the teachers responsible for the class and authorised staff may record or change them.

For staff only: students' Thai names, rooms and roll numbers on the class list.

For staff the School has approved: the competency report, which opens after signing in with the School's Microsoft account.

In normal use students see only the features for everyone; the others do not appear for them, and the School's server refuses them even if they are requested directly. If a staff-only control ever does appear to you, seeing it does not mean you are permitted to use it — see section 4.

4. Rules for using the Tool

You agree to use the Tool only for legitimate School purposes. You must not:

record, change, or delete attendance, competency tags or any other record for a class unless you are the teacher or authorised staff member responsible for it;

use another person's account, or let anyone else use yours;

attempt to access data belonging to classes you are not part of, or about students you do not teach;

copy, share or publish other students' names, attendance, grades or competency levels outside the School's own work;

attempt to bypass, disable, or interfere with the Tool's sign-in or security, or probe the systems behind it;

use the Tool to harass, impersonate, or mislead anyone;

copy, modify, or redistribute the Tool outside the School without the School's permission.

Misuse may be handled under the School's normal disciplinary and IT policies, and access to the Tool may be withdrawn.

5. Your account and your responsibility

You are responsible for what is done through your School account while you are signed in. Keep your account secure and sign out on shared computers. If you think someone else has used your account, tell the School promptly using the contact below.

6. Attendance and competency records

Attendance recorded through the Tool, and the competency levels calculated from teachers' returned rubric grades and attendance, form part of the School's records. It is the responsibility of teaching staff to ensure the marks and grades behind them are accurate, and to check how each rubric criterion is linked to a competency. If you believe a record about you is wrong, raise it with your teacher or the School — do not attempt to change it yourself.

7. Availability and changes

The Tool is provided as is and as available. The School does not guarantee that it will be available at all times, free of errors, or that it will always work with future versions of Google Classroom, which is operated by Google and can change without notice.

The Tool is early-stage software still being improved. Features may change, be added, or be removed. The School may suspend or discontinue it at any time.

To the extent permitted by Thai law, neither the School nor Loxley Orbit is liable for any loss arising from use of, or inability to use, the Tool. Nothing in these terms limits any liability that cannot be limited by law.

Attendance and competency levels are School records and should not be treated as infallible: if a decision about a student matters, confirm it with the responsible teacher rather than relying on the Tool alone.

8. Privacy

How the Tool handles personal data — including student names, attendance marks, returned rubric grades and competency levels — is described in the Privacy Policy, which forms part of these terms. Please read it alongside this document.

9. Google Classroom

The Tool works on top of Google Classroom and Google Workspace, which are provided by Google under Google's own terms. The competency report's sign-in uses the School's Microsoft account (Entra ID), provided by Microsoft under the School's own agreement with Microsoft. These terms cover the Tool only; your use of Google Classroom itself remains governed by the agreements between you, the School, and Google.

10. Changes to these terms

These terms may be updated as the Tool changes. When they are, the effective date above will change, and the current version will be published at this address. Continuing to use the Tool after an update means you accept the revised terms.

11. Ending access

The School may withdraw access to the Tool from any user at any time, including when someone leaves the School or breaks these rules. You can stop using the Tool at any time; if it was installed on your device by the School's administrator, ask the School to remove it.

12. Governing law

These terms are governed by the laws of the Kingdom of Thailand.
