Privacy Policy
Effective: September 27, 2026 / Updated: November 15, 2026
This policy explains how COCKPITOS Inc. (the "Operator"), which operates Tuned (the "Service"), handles your personal information.
1. Information we collect
- Information we receive from Google when you sign in with your Google account (name, email address, profile picture)
- Information we receive from Apple when you sign in with Apple (name and email address, or a relay address issued by Apple if you hide your email)
- Your profile (username, display name, avatar, native language, learning language and level, voice and other settings)
- Your learning history (lesson progress, word book, reviews, streaks)
- Your posts, likes, follows, corrections, reports and blocks
- Text you enter for AI conversations and translation-drill grading
- Voice you record for shadowing scores and voice input (used only to convert speech to text and not stored; we keep the scores and a record of sounds you find difficult)
- Your reactions to stories (such as likes and skips, used to tune recommendations) and how many times you use AI features
- For devices where you turn notifications on, the delivery address (a URL and encryption keys issued by your browser's push service). Deleted when you turn them off or delete your account
- Data stored on your device (cookies for sign-in, display language, theme and accent color; playback speed; audio and pages you save for offline use)
We do not collect your location, contacts, or photos on your device (other than an image you choose as your avatar).
2. Information in the kids app (Tuned Kids)
For child profiles created by a Family plan parent, we handle the following. We do not collect a child's email address, real name, photo or location.
- What the parent enters (nickname, name in English letters, school grade)
- The child's learning records in the kids app (lesson progress, words learned, pets and collection, diary notes and drawings, chess games) and the parent's comments, goals and gifts
- Text the child enters for AI conversations and lesson creation, and voice recorded for pronunciation practice (used only to convert speech to text and not stored)
- How many times AI features are used each day
We use this information only to provide the kids app, to report learning to the parent (on the parent page and, if the parent opts in, by weekly email), and to enforce daily usage limits.
The parent can delete all of a child's records by deleting the child's profile on the Family page.
3. How we use it
- To provide the Service (sign-in, lessons, word book, news audio, friends and posts)
- To tailor lessons and recommendations to your level and interests
- To prevent abuse (automatic checks of posts, handling reports, enforcing daily usage limits)
- To improve the Service, fix problems and answer inquiries
- To manage subscriptions if paid plans are offered
4. What other users can see
Your username, display name, avatar, native and learning language badges, plan and badges, public posts with their replies and corrections, and follower counts are visible to other users. Your email address is never shown.
Kids app information is never public. Only friends approved by both parents can see a child's nickname, pet, collection and streak. When parents send or approve a friend request, the other parent sees the child's nickname. A second parent who joins the family can see the children's progress.
5. Service providers
We use the following providers to run the Service. Some are based in the United States, so your information may be processed outside Japan. Each provider handles data under its own privacy policy.
- Supabase (database, sign-in and file storage; data stored in the Tokyo region)
- Vercel (hosting)
- Anthropic (Claude API for news summaries, lessons, AI conversations, grading and automatic post checks; we send only the text needed for each task)
- Google (Google sign-in, text-to-speech and speech-to-text; only news and lesson text is sent for text-to-speech, and only your recorded audio for speech-to-text)
- Apple (Sign in with Apple)
- OpenAI (speech-to-text for shadowing, voice input and pronunciation practice in the kids app; only the recorded audio is sent)
- Resend (sending email)
- Browser push services such as Google, Apple, Mozilla and Microsoft (if you turn notifications on; the content is encrypted)
- Stripe (payments for paid plans; card numbers are handled by Stripe and never stored by us — we only receive what we need to manage your subscription, such as your plan, payment status and billing country)
6. Sharing with third parties
We do not share your personal information with third parties without your consent, except where required by law. The Service currently shows no ads. If we introduce ads, we will update this policy in advance.
7. Retention and deletion
We keep your information while your account exists, as needed to provide the Service. You can delete your posts at any time, and you can delete your account and all of your data (profile, posts, word book, learning history, etc.) at any time from Settings → Delete my account. Deleted data cannot be recovered.
News stories, their summaries and audio are deleted automatically after about 30 days.
8. Your rights
You may ask us to disclose, correct, add to, delete or stop using the personal information we hold about you. We will verify your identity and respond as required by law. Contact: COCKPITOS Inc. (Representative: Shinsuke Ichiki), ONE FUKUOKA BLDG. 7F, 1-11-1 Tenjin, Chuo-ku, Fukuoka 810-0001, Japan / tuned.support@cockpitos.com
9. Security
We protect your information with encrypted connections and per-user access controls on our database.
10. Minors
If you are a minor, please use the Service with your parent's or guardian's consent. The kids app is used under a parent's supervision after the parent subscribes to the Family plan and creates the child's profile.
11. Changes
If we change this policy, we will post the changes and the new effective date on this page, and announce important changes in the app.
