Tracking & Cookies Data

We use cookies and similar tracking technologies to track the activity on our Service and we hold certain information.

Cookies are files with a small amount of data which may include an anonymous unique identifier. Cookies are sent to your browser from a website and stored on your device. Other tracking technologies are also used such as beacons, tags and scripts to collect and track information and to improve and analyse our Service.

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.

Examples of Cookies we use:

  • Session Cookies. We use Session Cookies to operate our Service.

  • Security Cookies. We use Security Cookies for security purposes.

Use of Data

unihongo.com uses the collected data for various purposes:

  • To provide and maintain the Service
  • To notify you about changes to our Service
  • To allow you to participate in interactive features of our Service when you choose to do so
  • To provide customer care and support

AI Features and Voice Data

When you use Unihongo’s AI features, we share your data with two service providers. Anthropic receives the messages you type, the transcripts of what you say and the surrounding conversation context, and its Claude models generate Sensei’s and Mocchi’s replies, translations, feedback and study reports. Google Cloud receives your pronunciation recordings and the text of Sensei’s replies, and its Gemini models and speech services grade your pronunciation and produce Sensei’s spoken Japanese. What you say to Sensei is turned into text by your device’s or browser’s speech recognition service (Apple or Google) before it is sent. Anthropic and Google process this information only as our service providers, under their own terms and privacy policies, and protect it to at least the standard described in this policy.

We save conversation transcripts and the reports generated from them in your account so that you can review your progress. You can delete an individual conversation from its report, or delete your account to remove all of them.

In the Unihongo mobile app we ask for your permission before your first AI conversation and record that choice with your account. You can withdraw it at any time in Profile → Privacy → AI processing. Withdrawing stops any further sharing with Anthropic and Google; it does not delete transcripts or reports that are already saved.

Deleting Your Account

You can delete your account at any time in the Unihongo mobile app: Profile → Your account → Delete account. We then cancel any active subscription and permanently delete your account along with your conversations, reports, pronunciation practice, flashcards and usage history. Questions and comments you posted for other learners stay on the Service, because others have answered and replied to them.

So that deleting an account and signing up again does not restore the free daily limits or the free trial, we keep a one-way code made from the deleted account's email address and, if you used Sign in with Apple, its Apple sign-in identifier. The code cannot be turned back into either. Alongside it we keep only how much of the free daily limits the account had used that day, deleted automatically at the end of that day (UTC), and whether it had used the free trial, deleted automatically after 12 months.

For the free starter experience, we also retain the offer assignment and usage totals with that one-way code for up to 12 months, so deleting an account does not renew the starter allowance.

Transfer Of Data

Your information, including Personal Data, may be transferred to — and maintained on — computers located outside of your state, province, country or other governmental jurisdiction where the data protection laws may differ than those from your jurisdiction.

If you are located outside Japan and choose to provide information to us, please note that we transfer the data, including Personal Data, to Japan and process it there.

Your consent to this Privacy Policy followed by your submission of such information represents your agreement to that transfer.

unihongo.com will take all steps reasonably necessary to ensure that your data is treated securely and in accordance with this Privacy Policy and no transfer of your Personal Data will take place to an organization or a country unless there are adequate controls in place including the security of your data and other personal information.

  • To protect and defend the rights or property of unihongo.com
  • To prevent or investigate possible wrongdoing in connection with the Service
  • To protect the personal safety of users of the Service or the public
  • To protect against legal liability

Security of Data

The security of your data is important to us but remember that no method of transmission over the Internet or method of electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your Personal Data, we cannot guarantee its absolute security.

Service Providers

We may employ third party companies and individuals to facilitate our Service ("Service Providers"), to provide the Service on our behalf, to perform Service-related services or to assist us in analyzing how our Service is used.

These third parties have access to your Personal Data only to perform these tasks on our behalf and are obligated not to disclose or use it for any other purpose.

Children's Privacy

Our Service does not address anyone under the age of 18 ("Children").
