Zentor

Terms of Service

Effective 26 June 2026 · Version 1.6 · Revised 7 October 2026

These Terms govern your access to and use of Zentor ("the Service"). Zentor is operated by Zensence Technologies Limited, a private company limited by shares registered in the Federal Republic of Nigeria ("Zensence", "we", "us") - Zentor is our trading brand. By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility

Zentor is for students, lecturers, administrators, and authorised parents/guardians of partner institutions. You must provide accurate registration details and have the right to use the institutional email or matriculation number you sign up with.

2. Your account

Students and lecturers sign in with their school email and a password they set; parents create an account with their own email and a password they set, linked to a ward by the ward's matriculation number and parent access code.

Keep your password and access codes confidential; you are responsible for activity under your account.
One account per person. Accounts are tied to a device for fraud prevention.
If you forget your password, a one-time code sent to your account email lets you reset it; registering requires no code beyond your parent access code.
Notify us promptly of any unauthorised use at support@zentor.ink.

3. Acceptable use

You agree not to:

Mark attendance for anyone other than yourself, or let anyone scan on your behalf ("proxy attendance").
Share login credentials, QR codes, spoken check-in codes, check-in sounds, or access codes to defeat attendance checks - for example, texting a code to someone outside the room or playing the check-in sound to them over a call.
Guess or try codes for a class you are not in.
Tick, write in or sign a paper register for anyone other than yourself.
Falsify your location, identity, photo, or device to bypass verification.
Probe, scrape, overload, reverse-engineer, or interfere with the Service or its security.
Use the Service for any unlawful purpose or in breach of your institution's regulations.

4. Attendance integrity

Zentor uses device binding, device passkeys (your phone or computer's fingerprint/Face ID), geolocation, facial verification, and fraud detection to keep attendance honest. Detected attempts at proxy attendance or tampering are logged and reported to your lecturer and institution. Academic consequences for such conduct are determined by your institution, not by Zentor.

Spoken code, sound, location and spot checks. Where your institution uses them, your lecturer may ask you to check in by typing a code they read out or by letting your phone listen for a short sound, instead of scanning a QR code. A code or sound only counts if you are in the room: the same location, device and identity checks apply, and a check-in from outside the class area waits for your lecturer's approval. Three wrong codes lock the code for that class until your lecturer unlocks it; you can still scan the QR code or ask to be marked present. Your lecturer may also let you check in by location alone: your check-in then counts only if your phone places you close to your lecturer, and faking your location (for example with an app that changes where your phone says it is) is proxy attendance and is treated as such. Your lecturer may also run a spot check, calling out a few names to see who is present (in an online class, asking you to unmute or turn on your camera). If you are called and are not there, that class does not count for you; in an online class, no answer costs you one attendance check. That decision is your lecturer's, not Zentor's, and they can correct it.

Online classes. Virtual classes are held on external platforms (e.g. Zoom, Google Meet, Microsoft Teams, Telegram), each subject to its own terms and privacy policy; Zentor only schedules the class and shares the join link. Where a lecturer enables attendance, you may enter the attendance code only while genuinely present in the class - entering a code you obtained without attending, or sharing it with someone who is not, is proxy attendance and is treated as above.

5. Availability

The Service is provided on an "as is" and "as available" basis. We do not guarantee uninterrupted or error-free operation, and attendance may also be recorded or corrected manually by authorised staff where needed.

The help assistant. Greatness, the in-app helper, gives general guidance on using Zentor and reads figures from your records. It can be wrong. If anything it says differs from your attendance record, the record is what counts, and your lecturer or institution decides any question about it.

6. Intellectual property

Zentor and its content, branding, and software are owned by Zensence Technologies Limited or our licensors. We grant you a limited, non-exclusive, non-transferable right to use the Service for its intended purpose. You may not copy, resell, or create derivative works without permission.

7. Disclaimers & liability

To the maximum extent permitted by law, we disclaim all warranties not expressly stated here, and we are not liable for indirect, incidental, or consequential damages, or for academic decisions made by your institution based on attendance data. Our total liability for any claim is limited to the amount you paid us (if any) in the 12 months before the claim.

8. Suspension & termination

We may suspend or terminate access that violates these Terms or poses a security risk. Your institution may also revoke access in line with its own policies.

9. Privacy

Your use of the Service is also governed by our Privacy Policy, which explains how we handle your data.

10. Governing law

These Terms are governed by the laws of the Federal Republic of Nigeria, without regard to conflict-of-laws rules.

11. Changes

We may update these Terms. Material changes will be communicated in-app or by email. Continued use after an update means you accept the revised Terms.
