1. About Kete Koha

Kete Koha is an online software platform operated by Ruiha Labs Limited (NZBN: pending), trading as Kete Koha ("Kete Koha", "we", "us", "our"). Our registered email is ketekoha@gmail.com and our website is www.ketekoha.co.nz.

Kete Koha provides a software-as-a-service (SaaS) platform that allows community organisations ("Customers", "Tenants", "you") to operate online raffle campaigns. Kete Koha does not conduct raffles itself and does not handle ticket sale proceeds.

2. Definitions

• Customer / Tenant: An organisation or individual who has a paid Kete Koha account.
• Ticket Buyer / Entrant: A member of the public who purchases raffle tickets through a Customer's public raffle page.
• Draw: The process by which a winning ticket is randomly selected from confirmed ticket entries.
• Slug: The unique URL identifier assigned to each Customer's raffle (e.g., "riverdale-dragon-boat").

5. Payment

Subscription fees are payable to Ruiha Labs Limited via bank transfer or as otherwise agreed. Ticket sale proceeds are collected directly by Customers — Kete Koha does not process, hold, or handle any ticket sale monies.

Customers are solely responsible for their own banking arrangements, receipt management, and any tax obligations related to their raffle proceeds.

6. Draw Integrity & Certificate System

Kete Koha is designed to make every draw transparent, fair, and verifiable. The following technical safeguards apply to every draw conducted through the platform.

6.1 Cryptographic Draw System

Kete Koha uses a cryptographically secure random number generator (crypto.getRandomValues()) to conduct draws. This function is compliant with NIST SP 800-90A and is the same technology used in banking and security applications. The system:

• Selects a winner uniformly at random from all confirmed ticket entries.
• Generates a cryptographic seed (four 32-bit random values concatenated in hexadecimal) which is recorded with the draw result.
• Records the seed permanently in the draw certificate — any third party can use this seed to independently verify the draw was conducted fairly.
• Uses rejection sampling to eliminate modulo bias, ensuring true uniform distribution.

6.2 Two-Witness Requirement

Every draw conducted through Kete Koha requires two witnesses to be present. The system enforces the following rules:

• Both witness names must be entered before the draw can be conducted.
• The two witnesses must have different names from each other.
• Witness names are permanently recorded in the draw record and draw certificate.

Customers are responsible for ensuring witnesses are genuinely independent and physically present at the time of the draw.

6.3 Draw Certificates

Following each draw, Kete Koha generates a draw certificate containing: the organisation name, raffle name, prize basket name and value, winner name, winning ticket number, draw date and time, both witness names, total ticket count, and the cryptographic seed.

Customers are advised to retain a printed or digital copy of each draw certificate for their records.

6.4 Customer Compliance Responsibility

7. Customer Responsibilities

• Notify winners promptly following the draw.

10. Why We Collect Your Contact Details

When you sign up for Kete Koha or purchase raffle tickets, we collect your contact details. Here is exactly why we need each piece of information:

For Customers (account holders)

• Name & email: To set up and manage your account, send you login credentials, respond to support queries, and send important notices about your subscription (renewals, updates to these terms).
• Phone number: To contact you urgently if there is an issue with your account or draw that requires prompt attention, and to verify your identity if you contact us for support.
• Organisation name: To create your unique raffle slug, personalise your raffle page, and identify your account in our records.
• Bank account number: This is your bank account (not ours). It is stored so that your public raffle page can display the correct payment details to ticket buyers. Kete Koha does not debit or access this account.

For Ticket Buyers (raffle entrants)

• Name: To identify your order, assign your ticket numbers, and — if you win — for the Customer to announce the winner and arrange prize collection.
• Email: So the Customer (raffle organiser) can confirm your ticket reservation, notify you of your ticket numbers once payment is received, and contact you if you win.
• Phone number (optional): As an alternative contact method for the Customer to reach you about your order or winnings.
