Privacy Policy

1. Who is responsible for your data?

KANGYM is responsible for the processing of personal data through the service.

For privacy questions, requests, or to exercise your data protection rights, contact us at:

privacy@kangym.com

2. What information do we collect?

We collect only the information necessary to operate, secure, and improve KANGYM.

Account information

When you create or use a KANGYM account, we may process:

• Your email address.
• Your account identifier.
• Your account creation date.
• Basic technical and security information.

Learning information

To provide your learning experience, we may store:

• Kanji you have studied.
• Correct and incorrect answers.
• Review history.
• SRS scheduling and review dates.
• Learning progress.
• Study activity.
• Streaks.
• Stories you edit or create.
• Feedback you choose to send us.

This information allows KANGYM to remember your progress and determine what you should study or review next.

3. How do we use your information?

We use your information to:

• Create and maintain your account.
• Save your learning progress.
• Schedule kanji reviews.
• Calculate progress and streaks.
• Show your study activity.
• Personalize your learning experience.
• Keep KANGYM secure.
• Detect bugs and technical problems.
• Understand how the learning system performs.
• Improve KANGYM.

We do not sell your personal data.

We do not share your personal data with advertisers.

4. Improving KANGYM

During the beta, we may analyze learning data to understand whether KANGYM is working effectively.

For example, we may analyze:

• Which kanji are answered incorrectly more often.
• Which stories or kanji cause more difficulty.
• How frequently users return to study.
• Whether review workloads become too large.
• Where users stop or struggle during the learning process.
• Which parts of KANGYM should be improved.

Whenever reasonably possible, this analysis is performed using aggregated or pseudonymized information rather than directly identifying individual users.

5. Legal bases for processing

The legal basis depends on why the information is being processed.

Providing KANGYM

Some processing is necessary to provide the service.

For example, KANGYM cannot provide spaced repetition, progress tracking, or scheduled reviews without storing your learning history.

Legitimate interests

We may process limited information where necessary to:

• Protect the security of KANGYM.
• Prevent abuse.
• Diagnose technical problems.
• Evaluate and improve the learning experience.

We only rely on legitimate interests where those interests do not override your rights and freedoms.

Consent

Where required, we ask for your consent before using optional analytics cookies or similar technologies.

You can withdraw your consent at any time.

6. Cookies and optional analytics

KANGYM can be used without optional analytics cookies.

If you accept optional analytics, we may collect additional information such as:

• Response times.
• Interactions with features or screens.
• Actions performed during a study session.
• Basic browser or device information.
• Technical performance information.

We use this information to understand how KANGYM is used and identify areas that can be improved.

Rejecting optional analytics does not prevent you from studying or using the core features of KANGYM.

You can change your preferences at any time through Cookie Settings.

More information is available in our Cookie Policy.

7. Automated learning decisions

KANGYM automatically uses your learning history to determine things such as:

• When a kanji should appear again.
• Which reviews are due.
• Which content should be prioritized.
• How your study workload should be organized.

These automated decisions are used only to provide and personalize the learning experience.

They are not used to make legal or similarly significant decisions about you.

8. Service providers

KANGYM may use trusted third-party providers to operate the service.

These providers may assist with:

• Hosting and infrastructure.
• Databases.
• Authentication.
• Email delivery.
• Analytics.
• Error and performance monitoring.

They may process personal data only as necessary to provide their services to KANGYM and subject to the applicable contractual and data protection requirements.

We do not authorize service providers to use your personal data for their own advertising purposes.

9. International data transfers

Some service providers may process information outside the European Economic Area.

Where required by applicable law, KANGYM uses appropriate safeguards for international transfers, such as adequacy decisions or Standard Contractual Clauses.

10. How long do we keep your information?

We keep account and learning information while your KANGYM account remains active and for as long as reasonably necessary to provide the service.

If you delete your account, we will delete or anonymize the personal data associated with it, except where limited retention is necessary for legal, security, fraud-prevention, or technical purposes.

Information contained in backups may require additional time to be fully removed.

11. Your rights

Depending on applicable data protection law, you may have the right to:

• Access your personal data.
• Correct inaccurate information.
• Request deletion of your information.
• Request restriction of certain processing.
• Object to processing based on legitimate interests.
• Receive certain information in a portable format.
• Withdraw consent where processing is based on consent.

To exercise these rights, contact:

privacy@kangym.com

We may request reasonable information to verify your identity before completing certain requests.

If you are in the European Union, you also have the right to lodge a complaint with the relevant data protection authority.

In Spain, the supervisory authority is the Agencia Española de Protección de Datos (AEPD).

12. Deleting your account

You can request deletion of your KANGYM account and associated personal data through:

Account Settings → Delete account

or by contacting:

privacy@kangym.com

Account deletion is permanent and may remove your learning progress, reviews, study history, custom stories, and other information associated with your account.

13. Teenagers and children

The current KANGYM beta is intended for users aged 14 or older.

If you are under 14, you should not create or use a KANGYM account during the current beta.

If applicable law in your country requires you to be older to provide valid consent on your own, that higher age requirement applies.

If KANGYM later allows users under 14, we will introduce the appropriate parental or legal guardian authorization process before collecting personal data from those users.

We aim to present privacy information in clear and understandable language, particularly when KANGYM is used by younger users.

14. Security

We use reasonable technical and organizational measures designed to protect personal information against:

• Unauthorized access.
• Loss.
• Alteration.
• Disclosure.
• Misuse.

However, no online service can guarantee absolute security.

15. Changes to this Privacy Policy

KANGYM will continue to evolve, and this Privacy Policy may change as the service develops.

When we make changes, we will update the Last updated date at the top of this page.

If a change significantly affects how we process personal data, we will provide additional notice where appropriate.
