Your Account

You sign in with a Gohesive Account (account.gohesive.com), which holds your email address, sign-in methods and subscriptions. Its own privacy policy covers that data. Nikkanji receives your email address, an account identifier and which subscriptions you have.

What Nikkanji Stores

Your learning: your reviews and their results, your course progress, settings, and the time you spend studying.

What you add: your name, your hanko design and town if you set them, words you save, notes and memory hooks, events you plan in Tonight, and photos you take of Japanese text.

Your voice: when you practise speaking, the recording is sent to be turned into text and checked. Recordings you choose to keep (for example for a coach) are stored with your account; others are not kept after they are checked.

AI features: what you write or say in conversation practice and other AI features is sent to an AI model provider to produce the reply, and the conversation is stored with your account so you can review it.

Subscriptions in the app: the App Store or Google Play processes payment. RevenueCat tells us which plan is active for your account, and holds your email address, name, device details and learning totals so we can find your account and help with your subscription. We do not receive your card details.

Reminders on the web: if you turn them on, your browser's push subscription and reminder time.

How you use the app: the screens you open, the lessons and practice you start and finish, your learning totals (such as lessons passed, reviews done, and words and kanji known), the steps of signing in and subscribing, your device model and operating system, the app version, your language, time zone and approximate country, and the name you give in the app. On some screens, such as the first steps, placement, the paywall and lessons, we also record what the screen shows as you use it (where you tap and scroll and what appears), with anything you type, your name and seal, and pictures and sound hidden; screens where you write to or speak with the app are not recorded. In the app, we also note where the install came from (an App Store or Google Play campaign, or neither), without any advertising identifier. These records carry your account identifier (before you sign in, a random identifier for the device) and, once you have an account, your email address, so we can help you when you contact us. They do not include what you write or say.

Error reports: when something goes wrong, the error, the screen it happened on and the app version, with your account identifier.

How We Use It

To run the app for you: schedule your reviews, keep your devices in sync, check your speaking and writing, and show your progress. To understand which parts of the app help people learn and where they get stuck, and to find and fix errors. We do not sell your data, show advertising, or track you across other companies' apps and websites.

Services We Use

Cloudflare hosts the app, its database and stored files, and turns speech into text. An AI model provider produces the replies in AI features, under terms that do not allow it to train its models on your data. Google Cloud Text-to-Speech reads aloud words you add. RevenueCat, Apple and Google handle in-app subscriptions, and RevenueCat holds the account details described above. Mixpanel receives the records of how you use the app, with your email address and name once you have an account, and Sentry receives error reports; both store this data in the European Union.

How Long We Keep It

We keep your data while your account exists. When you delete your account, Nikkanji deletes everything it holds for you. See Account Deletion.

Your Choices

You can export your data from Me, Settings, and delete your account from Me, Settings, Delete Account. You can turn off the records of how you use the app on a device in Me, Settings, Share usage data, which also stops our server from sending your learning totals to Mixpanel and RevenueCat; error reports are still sent. For a copy of your data, a correction or any question, email support@nikkanji.com. You may also complain to the UK Information Commissioner's Office.

Children

Nikkanji is not directed at children under 13.
