Privacy Policy

1. Introduction

InitialJ ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Japanese language learning platform.

2. Information We Collect

We collect information that you provide directly to us:

• Account Information: Email address, username (optional), and password
• Learning Progress: Your kanji and vocabulary progress, SRS stage data, and review history
• Settings: Your learning preferences and app settings
• Communication: Messages you send to us through contact forms or support

We also automatically collect certain information when you use our Service:

• Usage data and analytics
• Device information and browser type
• IP address and general location data

Specifically, when you sign up and each time you log in (refreshed at most once per hour), we store on your account row:

• IP address — the public IP your request came from, used for security and abuse detection
• User-agent — your browser and OS string, used to render the right UI and to debug device-specific issues
• Timezone — the IANA timezone reported by your browser (e.g. Europe/Paris), used to align daily XP and reviews to your local day
• Accept-Language — your preferred languages, used to default the UI to French or English

These signals never leave our database — we do not send them to any third-party geolocation or fingerprinting service. We use them only for security (multi-account detection, suspicious login alerts), for product analytics on our own infrastructure, and to debug issues you report. You can request deletion of your account at any time and these fields are removed with it.

3. How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve our Service
• Track your learning progress and personalize your experience
• Send you verification codes, welcome emails, and important updates
• Respond to your inquiries and provide customer support
• Monitor and analyze usage patterns to improve our Service
• Detect, prevent, and address technical issues

4. Data Storage and Security

We implement appropriate technical and organizational measures to protect your personal information. Your data is stored securely and we use industry-standard encryption for sensitive information such as passwords.

However, no method of transmission over the Internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security.

5. Data Retention

We retain your personal information for as long as your account is active or as needed to provide you with our Service. If you delete your account, we will delete or anonymize your personal information, except where we are required to retain it for legal purposes.

6. Sharing Your Information

We do not sell, trade, or rent your personal information to third parties. We may share your information only in the following circumstances:

• Service Providers: With trusted third-party service providers who assist us in operating our Service (e.g., email delivery, hosting)
• Legal Requirements: When required by law or to protect our rights and safety
• Business Transfers: In connection with a merger, acquisition, or sale of assets

7. Your Rights

You have the right to:

• Access and receive a copy of your personal data
• Correct inaccurate or incomplete information
• Request deletion of your personal data
• Object to or restrict processing of your data
• Export your data in a portable format
• Withdraw consent at any time

To exercise these rights, please contact us at support@initialj.com

8. Cookies and Tracking

We use cookies and similar tracking technologies to track activity on our Service and store certain information. You can instruct your browser to refuse all cookies or to indicate when a cookie is being sent. However, if you do not accept cookies, you may not be able to use some portions of our Service.

9. Children's Privacy

Our Service is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately.

10. International Data Transfers

Your information may be transferred to and maintained on computers located outside of your state, province, country, or other governmental jurisdiction where data protection laws may differ. By using our Service, you consent to the transfer of your information to our facilities and those third parties with whom we share it as described in this policy.

11. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date. You are advised to review this Privacy Policy periodically for any changes.
