Privacy Policy
This policy explains how the iPhone app DriveKata (“the app”) handles information. “We” and “us” mean the developer of the app.
Information stored on your device
The app does not require an account. It stores your settings, your practice progress and results, and the answers you give during setup (such as your exam date) on your device. It also records which free runs you have used. This information is used to run the app. Your setup answers, including your exam date, are never sent to us. The app has no ads, and it does not track you.
Anonymous usage data
To learn which parts of the app help people prepare, the app sends anonymous usage events: which screens and modes are used, which settings are changed, how long runs last, run results as scores and the ids of the rules that were broken, and the steps of a purchase (for example, that the plans page was opened, which plan was chosen, and whether a purchase or a restore of purchases was completed, cancelled or failed). Each event also carries the app version, the iOS version, the type of iPhone and the phone’s language. The events are tied to a random ID the app creates on your device, not to your identity: not to your name, your email, your Apple Account or any device identifier. They never include your setup answers, your exam date or anything you type, and they are not used for advertising or to track you across other companies’ apps or websites.
The events are processed by PostHog (posthog.com), which provides product analytics for us. PostHog is set not to keep your IP address and not to work out your location from it.
You can turn this off at any time in the app, in Settings → Share anonymous usage data. When you turn it off, the app sends one last event saying so, then sends nothing more, deletes any events it was waiting to send and deletes the random ID. If you turn it on again, the app creates a new random ID, so later events are not connected to earlier ones.
Purchases
Purchases and subscriptions are processed by Apple through the App Store. We never see your payment card details. Apple tells the app which purchases are active so it can unlock them. Apple’s handling of your information is covered by Apple’s Privacy Policy.
Crash reports and diagnostics
To find and fix problems, the app may send crash reports and technical diagnostics, such as the device model, iOS version, app version and details of the error. These reports do not include your name, contact details or other personal information, and we do not use them to identify you or to track you. They are processed by Sentry (sentry.io), which provides crash reporting for us; we only use providers that protect this information to the same standard as this policy. Crash reports are kept only as long as needed to fix problems and are then deleted.
If you contact us
If you email us, we receive your email address and what you write. We use it to reply and to help you.
Sharing
We do not sell your personal information, and we do not share it for advertising. The app links to other websites, such as MenkyoHub.jp, which have their own privacy policies.
Children
The app is not directed at children under 13, and we do not knowingly collect personal information from children under 13.
Deleting your data
Deleting the app removes the information it stores on your device, including the random ID used for anonymous usage data; if you install the app again, it starts with a new one. To stop free runs being reused, the app may also keep a note of which ones you have used in the iOS Keychain, which can remain after the app is deleted. The note contains no personal information and is never sent to us. Copies may also remain in your device backups until they are replaced. You can ask us to delete any information we hold about you, such as your emails, by contacting us.
Changes to this policy
We may update this policy. The new version will be posted on this page with a new effective date.
