Privacy Policy

1. Overview

This Privacy Policy explains how The Koharu Project (“we”, “us”) collects, uses, and shares information when you use our website and related services (the “Service”). The Service is 18+ only.

2. Information we collect

• Account info — email, display name, and membership tier when you sign up or log in
• Age confirmation — that you confirmed you are 18+ to enter the Service
• Usage data — pages visited, features used, approximate device/browser info, and diagnostic logs needed to run chat and media features
• Chat & creator content — messages and custom companion settings you create so the Service can respond and remember your session (storage may be on-device and/or on our servers as features evolve)
• Payments — when billing is enabled, our payment processor handles card details; we typically receive limited billing metadata (e.g. status, plan), not full card numbers
• Communications — emails or messages you send to support or legal contacts

3. How we use information

• Provide chat, images, vault, and account features
• Enforce 18+ access and our Content Policy
• Process memberships and prevent fraud or abuse
• Improve reliability, safety, and user experience
• Comply with law and respond to lawful requests
• Communicate about the Service (e.g. important notices)

4. AI processing

Chat messages and related prompts may be sent to third-party AI providers so companions can reply and generate images. Do not share information in chat that you are not comfortable processing for that purpose. Providers process data under their own terms and our contractual arrangements with them.

5. Cookies & local storage

We use cookies, local storage, and similar technologies for age confirmation, session preferences, membership flags, and chat history on your device. You can clear browser storage; doing so may log you out or reset local-only data.

6. Sharing

We may share information with:

• Service providers (hosting, AI APIs, payments, analytics, security) who process data for us
• Authorities when required by law or to protect rights, safety, or the Service
• A buyer or successor if we are involved in a merger, sale, or similar transaction

We do not sell your personal information as a product list.

7. Retention

We keep information as long as needed to provide the Service, comply with law, resolve disputes, and enforce agreements. You may request deletion of account data where applicable; some records may be retained for legal or security reasons.

8. Security

We use reasonable technical and organizational measures to protect information. No method of transmission or storage is 100% secure.

9. Children

The Service is not directed to anyone under 18. We do not knowingly collect personal information from minors. If you believe a minor has used the Service, contact us and we will take appropriate steps.

10. Your choices

Depending on your location, you may have rights to access, correct, delete, or export personal data, or to object to certain processing. Contact us to make a request. You can also stop using the Service and clear browser data.

11. International users

The Service may be hosted or processed in the United States or other countries. By using it, you understand your information may be transferred to those locations.

12. Changes

We may update this Privacy Policy. Continued use after changes means you accept the updated policy. Check the “Last updated” date.
