KIKIBUN PRIVACY POLICY

1. Introduction

Kikibun is a privately maintained digital platform intended to assist individuals in learning English through various educational materials, exercises, and features. Kikibun is not a company, corporation, or registered legal entity. It is a personal project operated and administered by a natural person acting in an individual capacity.

This Privacy Policy explains how personal data may be collected, processed, and safeguarded in connection with your use of the Kikibun platform. By accessing or using the platform, you acknowledge and agree to the practices described in this Policy.

2. Information We Collect

2.1. No User Account Required

Kikibun does not require user registration or the creation of a user account. The platform is accessible without submitting personally identifiable information (PII), such as names or passwords.

However, users may optionally submit their email address through a dedicated subscription form for receiving newsletters, product updates, or educational materials. Submission of an email address is entirely voluntary and constitutes explicit consent to process that data for the specified communication purpose.

2.2. Information Collected Automatically

• Technical Access Data: When you access Kikibun, certain technical information may be collected automatically for operational and security purposes. This may include, but is not limited to, IP address, browser type, operating system, timestamps, and other technical identifiers.
• Service Infrastructure: Kikibun is hosted on Cloudflare’s infrastructure. Any technical data collection or logging is performed solely by Cloudflare for traffic routing, protection against abuse, and ensuring service availability. Kikibun itself does not log or store this data directly.

3. How We Use Your Information

• Platform Operation:

  To maintain and protect the platform, ensure availability and performance, and safeguard against security threats.

• Newsletter Communication:

  If you submit your email through the newsletter form, we use it solely to deliver the subscribed content.

4. Disclosure of Information

• Cloudflare: Technical information may be processed and stored by Cloudflare in accordance with its own Privacy Policy.
• Legal Requirements: We may disclose information if legally required to do so by competent authorities or to comply with applicable law.
• Consent: We will not share any submitted personal information without your explicit consent unless required by law.

5. Data Retention

We retain voluntarily submitted email addresses only for as long as necessary to fulfill communication purposes or until the user unsubscribes.

6. Security

While we do not store sensitive personal data, we take reasonable measures to protect any limited information processed via the newsletter form and to ensure our infrastructure (via Cloudflare) is protected against unauthorized access or disruption.

7. International Data Transfers

Cloudflare may process technical connection data in global locations. Any data is handled in compliance with applicable data protection frameworks such as the GDPR and the Data Privacy Framework (DPF) where applicable.

8. Children’s Privacy

Kikibun is not directed at children under the age of 18. We do not knowingly collect any personal data from minors. If you believe a child has submitted personal data, please contact us for prompt deletion.

9. Email Subscriptions

Kikibun may offer users the ability to subscribe to email updates, such as newsletters or language learning content, by voluntarily submitting their email address via a designated subscription form.

By entering and submitting your email address, you provide explicit and affirmative consent (opt-in) to receive communication from Kikibun. This submission serves as the legal basis for processing under Article 6(1)(a) of the GDPR and equivalent frameworks.

Emails are sent directly through a manually maintained system developed and operated by Kikibun. Message delivery is handled by Spacemail, an independent email delivery provider, using a verified custom domain controlled by Kikibun.

No data is shared with third-party marketing platforms or used for automated decision-making, profiling, or behavioral analysis. Your email address is stored securely and used exclusively for the stated communication purpose.

You may unsubscribe at any time by clicking the unsubscribe link included in each email or by contacting [email protected]. Upon unsubscription, your email address will be promptly removed from our mailing list and not retained.

10. Changes to This Policy

We may revise this Privacy Policy from time to time. The updated version will be posted on this page with the “Last Updated” date. Your continued use of the platform constitutes acceptance of any changes.
