Privacy Policy
Last updated: October 27, 2026
DEKITA Inc. (株式会社DEKITA) ("DEKITA", "we", "us") runs the NihongoDekita Podcast app at podcast.nihongodekita.com (the "App"). This policy explains what personal information we collect, why, and the choices you have. We handle personal information in line with Japan's Act on the Protection of Personal Information, and, for users in the European Economic Area and the UK, the GDPR.
1. Information we collect
- Account information: your email address, and a display name you choose. If you sign in or link with Discord, we also receive your Discord user ID and username.
- Subscription information: whether your subscription is active, and your Stripe customer and subscription IDs. For Speaking Club, we also keep a record of your subscription (its status and renewal date) with the email address and Discord ID linked to it. We also record when you join or leave Speaking Club or Transcript Access. We never see or store your full card number. Payments are handled by Stripe.
- Learning activity: words you save, flashcard results, episodes you complete, listening position, whether you watch or listen to an episode and how long you play it, and practice history. This is used to show your progress and leaderboard, and, as totals only, to see how the App is used.
- Feedback: reports you send us, including the page, the item you flagged, and any screenshot you choose to attach.
- Speaking Club waitlist: if you join the waitlist, the email address you give us and the date you joined.
- Technical information: basic logs needed to run and secure the App (such as device type and error information), and your appearance and install preferences saved on your own device.
- Page speed. We use Vercel Speed Insights to measure how fast our pages load. Each time a page loads, it records anonymous performance numbers: how long the page took to load, the page address, your device type, browser, operating system, connection speed and country. This information cannot identify you or follow you from page to page. We use it only to find and fix slow pages. The data is processed by Vercel, our hosting provider.
2. How we use it
- To create your account, log you in with a one-time email link, and give you access to what your plan includes.
- To process your subscription and send receipts, confirmations and important service emails.
- We may send copies of account and subscription emails to our internal support mailbox so we can respond to account questions and maintain service records.
- For Speaking Club members: to add you to the Speaking Club Discord server when you ask us to, and to give or remove the Speaking Club role in Discord based on your subscription.
- To show your progress, saved words and leaderboard (only your display name and activity counts are shown to other members).
- To see, as totals only and without names, how episodes and features are used, so we can improve them.
- To respond to feedback, fix problems and keep the App secure.
- To email you when a new Speaking Club batch opens, if you joined the waitlist.
We do not sell your personal information, and we do not use it for advertising.
3. Who we share it with
We use these service providers to run the App. They process data only to provide their service to us.
| Provider | Purpose |
|---|---|
| Supabase | Database, login and file storage |
| Vercel | Hosting the App |
| Vercel Speed Insights | Measuring how fast pages load |
| Stripe | Payments and subscription management, including Speaking Club |
| LaunchPass | Billing for members who joined Speaking Club through our earlier sign-up page, under its own terms |
| Resend | Sending emails |
| Discord | Optional sign-in, adding Speaking Club members to the Discord server, and giving or removing the Speaking Club role |
| YouTube (Google) | Showing episode videos. YouTube may collect data when you play a video. |
Some of these providers are outside Japan, so your information may be processed in other countries, including the United States. We choose providers that apply appropriate safeguards. We may also disclose information when the law requires it.
4. How long we keep it
We keep your information while your account is open. If you delete your account in the App, we end your subscription as described in the Refund and Cancellation Policy and delete your account, saved words, progress and feedback, including screenshots. We keep billing and tax records for 7 years, as required by law. We keep waitlist emails until the next batch opens and you have had the chance to join, or until you ask us to remove yours. Email info@nihongodekita.com to be removed at any time.
5. Your choices and rights
If you signed up with email, you can change your display name in the App. If you signed in with Discord, your name comes from Discord, so change it in the Discord app. You can delete your account in the App (Account page) and cancel your subscription at any time. You can also ask us to access, correct, or delete your information, or to stop using it, by emailing info@nihongodekita.com. We will reply within a reasonable time. If you are in the EEA or UK, you may also complain to your local data protection authority.
6. Cookies and similar technology
The App uses only what it needs to keep you logged in and remember your settings. We do not use advertising cookies.
7. Security
We protect your data with access controls, encrypted connections and private file storage. No system is perfectly secure, so please keep your login email account safe.
8. Children
You must be 15 or older to use the App. If you are under 18, you need the consent of a parent or guardian. If you believe a child under 15 has given us information, contact us and we will delete it.
9. Changes
We may update this policy. We will post the new version here with a new date, and tell you by email if the changes are significant.
