Privacy Policy

This Privacy Policy explains how LenGaki collects, uses, stores, and shares personal information when you visit our website, create an account, use our Japanese learning lessons, or interact with our services.

LenGaki is a language-learning platform designed to help learners study hiragana, katakana, kanji, vocabulary, grammar, JLPT content, and related study tools. To keep the service running, improve learning outcomes, and measure marketing performance, we process limited user information through our own systems and through trusted third-party services.

We may collect information that you provide directly, information created when you use the platform, and information received from third-party services connected to your account or payment activity.

LenGaki uses cookies and similar technologies to keep you signed in, remember preferences, understand how the platform is used, and measure advertising performance.

We may use essential cookies for authentication and security, analytics cookies for usage measurement, and advertising cookies for attribution and remarketing. Some cookies are set by us, while others are set by analytics or advertising partners.

We use analytics to understand which pages are visited, which learning features are popular, and how users move through the platform. This helps us improve navigation, content quality, and feature design.

Our site currently uses Google Analytics for page-level measurement and may also use internal analytics stored in our application database to summarize learning progress, practice activity, and performance trends.

We use advertising tools to understand which marketing campaigns lead to signups, subscriptions, and other meaningful actions. This allows us to evaluate ad performance and improve future campaigns.

LenGaki currently uses Meta Pixel and Meta Conversions API. These tools may receive events such as PageView, Login, CompleteRegistration, InitiateCheckout, and Purchase, along with event identifiers for deduplication and attribution.

We do not sell your personal information in the conventional sense. However, we may share information with service providers and partners that help us operate LenGaki, process payments, deliver analytics, or run advertising measurement.

The information shared is limited to what is necessary for the specific service being performed. We aim to keep this sharing narrow, purposeful, and aligned with the function being provided.

Your account data is used to operate the platform and personalize your learning experience. This includes progress tracking, streak calculation, saved preferences, and access control for paid features.

We may store aggregated learning records such as quiz scores, daily practice time, flashcard review counts, and completion status for different study modules.

If you purchase a subscription or make a payment, the transaction is processed through third-party payment providers. We do not store full card numbers on our servers.

We may receive confirmation data from the payment provider, such as transaction IDs, subscription state, payment success or failure, renewal status, and the email address associated with the transaction.

Some billing events may be mirrored into our internal records so that we can manage access, customer support, subscription status, and fraud prevention.

LenGaki relies on trusted third-party services to deliver parts of the product. Each provider has its own privacy practices, and their use of your information is governed by their own policies.

These integrations may include services for authentication, analytics, payment, and ad conversion measurement. In some cases, those partners may process data in countries other than your own.

We use the information we collect for product operation, security, analytics, marketing measurement, account support, billing, and communication.

We only process information where we have a legitimate operational reason, a contractual need, a legal obligation, or your consent where required.

We keep personal information only as long as necessary for the purposes described in this policy, unless a longer retention period is required by law, payment processing, or security needs.

Some learning history and analytics records may be retained in aggregated or de-identified form to preserve progress, evaluate feature quality, or support business reporting.

If you close your account or stop using the service, some records may still remain in logs, backups, invoices, or payment systems for a limited time because they are required for operational, legal, or fraud-prevention reasons.

Depending on your location, you may have rights to access, correct, delete, or restrict certain personal information, and you may be able to object to or opt out of specific types of processing.

You can also manage browser cookies through your browser settings. Blocking essential cookies may affect login, payment flows, or core site functionality.

Where applicable, you may also request a copy of the personal information we store about you or ask us to correct outdated account information.

LenGaki is intended for general educational use. We do not knowingly collect personal information from children where such collection is prohibited by law. If you believe a child has provided personal data to us without appropriate consent, please contact us so we can investigate and remove the data where required.

Parents or guardians who believe a minor has created an account should contact us so we can review and take appropriate action.

We use reasonable technical and organizational safeguards to protect personal information against unauthorized access, misuse, loss, alteration, or disclosure.

No online service can guarantee absolute security, but we aim to reduce risk through access controls, environment separation, provider selection, and limited data collection.

Because LenGaki and its third-party providers may operate globally, your information may be processed in jurisdictions outside your own country.

When data moves across borders, we rely on the applicable provider safeguards and our own operational controls to help protect the information during processing.

We may update this Privacy Policy when our features, partners, or legal requirements change.

If the changes are significant, we may display a notice on the site, update the effective date, or communicate the update through the service where appropriate.
