K4 Edu Solutions · Kalixen Online Store

Last updated: 6 August 2026

The short version

This policy explains how Kalixen Online Store, trading as K4 Edu Solutions, handles personal data. We are the Personal Information Controller for the purposes of Republic Act No. 10173, the Data Privacy Act of 2012, and its Implementing Rules and Regulations.

1. What we collect, and why

DataWhy we hold itBasis
Name, email address, mobile number To process your order, deliver your access code, issue receipts, and answer support requests Necessary to perform our contract with you
Delivery address To ship a printed copy. Collected only for orders that include a physical book Necessary to perform our contract with you
Order record — reference, item, amount, payment status, payment reference Fulfilment, refunds, accounting and tax records Contract, and our legal obligations as a registered business
A one-way hash of the access code issued to you So we can tell which code belongs to which order without storing the code itself Legitimate interest in preventing fraud and resolving support cases
Access and device cookies (k4tok, k4dev) To keep you signed in to the portal and enforce the 2-device limit on each code Strictly necessary for a service you asked for
Anonymous usage events — page path, referrer, country, random session id To understand which parts of the site and book are actually used Legitimate interest in improving the product

2. What we deliberately do not collect

Some of this is worth stating plainly, because it is unusual:

Because our analytics collect no personal data, this site does not need — and does not show — a cookie consent banner. The only cookies set are the two strictly necessary portal cookies named above.

3. Who else processes your data

We use a small number of service providers, each for one clearly defined job. They act on our instructions and may not use your data for their own purposes.

ProviderWhat they handle
PayMongo Philippines, Inc. Payment processing. They receive your name, email and mobile number to process the transaction and are the ones who handle payment credentials. PayMongo is regulated by the Bangko Sentral ng Pilipinas.
Resend Sending your confirmation and access-code email. They receive your email address and the contents of that message.
Cloudflare Website hosting, security, and the database holding order records. Data is stored on Cloudflare infrastructure, which may be outside the Philippines.

We do not sell, rent or trade personal data. We do not share it with anyone else except where the law compels us to.

Transfers outside the Philippines

Our hosting and email providers operate internationally, so your order data may be stored or processed abroad. Where that happens we remain accountable for it under RA 10173 and use providers that offer a comparable level of protection.

4. How long we keep it

5. How it is protected

No system is perfectly secure, and we will not claim otherwise. If a breach ever affects your personal data, we will notify you and the National Privacy Commission as RA 10173 requires.

6. Your rights under RA 10173

As a data subject you have the right to:

To exercise any of these, email k4edusolutions@gmail.com. We respond within 15 working days. There is no charge.

7. Children

This site is intended for senior high school, college and professional learners. We do not knowingly collect personal data from children under 13. If you believe a child has given us personal data, write to us and we will delete it.

8. Changes to this policy

We will update this page when our practices change, and revise the “last updated” date above. Material changes affecting existing customers will be sent by email.

9. Contact

Questions, requests and complaints about personal data all go to the same place. As a sole proprietorship below the National Privacy Commission's mandatory registration thresholds, we have not appointed a separate Data Protection Officer; the author handles these personally.
