1. Introduction
Radiant is provided by Loshi Technologies, LLC (“Radiant,” “we,” “us,” or “our”). This policy explains how we collect, use, share, retain, and delete information when you use the Radiant mobile app or website.
2. Information We Collect
- Account and profile information, including your email address, name, authentication provider, onboarding answers, goals, and preferences.
- Practice information, including challenges, responses, scores, progress, streaks, feedback, and the content you send to Celesta.
- Recordings and practice media. With your device permissions, Radiant can capture your voice and video during speaking exercises and access photos you choose for slides. The app can save recordings, slide media, and video exports on your device. When you use transcription or assessment features, audio may be sent to our systems or speech providers for processing. We may store transcripts, speech metrics, scores, and feedback with your practice history.
- Sharing and peer feedback information. If you submit a TikTok or Instagram link, we may store the link, platform, and review status. If you opt in to recommendations, approved links may be shown to other Radiant users. If you submit a comment screenshot through peer feedback, we receive the image to process the submission and store a receipt, including a file fingerprint and submission time. This submission flow keeps the receipt after processing the image.
- Device, app, and diagnostic information, such as device and operating system type, app/build version, push token, feature usage, and limited error and performance logs.
- Subscription and transaction status. We do not receive or store your full payment-card number. The payment provider depends on where you buy your subscription.
3. How We Use Information
We use information to operate and improve Radiant, including to:
- authenticate you and maintain your account;
- deliver, personalize, and measure practice and coaching;
- transcribe and analyze speech you submit for speaking features;
- generate AI-assisted feedback, practice content, and Celesta coaching;
- process subscriptions, prevent fraud, and provide support;
- operate and moderate sharing and peer feedback features;
- send reminders or push notifications based on your settings; and
- secure, troubleshoot, and improve the app.
AI-generated content can be inaccurate or unsuitable. You can report a Celesta response from its message actions for our review.
4. Service Providers and Sharing
We use service providers that process information for the purposes above:
- Supabase provides authentication, database, and storage services. Railway hosts backend services that handle app requests.
- Speech processing can run on our systems or through providers such as Deepgram, depending on the feature and configuration.
- Microsoft Azure Speech processes audio and reference text submitted for pronunciation assessment.
- OpenRouter and its model providers process prompts, transcripts, and practice context needed to generate AI-assisted feedback and Celesta responses.
- RevenueCat helps manage subscription status. Apple, Google Play, or Stripe may process purchases, depending on where you subscribe.
- Expo processes push-notification delivery tokens and sends notifications on our behalf.
- Appstack helps measure installs and campaigns. Attribution may use app events, campaign data, and device identifiers where available under your device settings and permissions.
If you choose to send a video to TikTok or Instagram, that platform receives the video and handles it under its own policies and your account settings. Manage or remove posts on the platform where you published them.
We may also disclose information when required by law, to protect people or our services, or in connection with a business transfer. We do not sell personal information or use your practice content for third-party advertising.
5. Retention and Deletion
We keep account and practice history to provide the service, including when you return to past exercises. Retention varies by the type of information and why we use it. We may keep limited records after account deletion for security, fraud prevention, disputes, accounting, or legal obligations.
To request deletion of your account and associated data, use Settings → Account → Delete Account or follow the instructions on our account deletion page. If the app reports that deletion is incomplete, contact us. Manage copies you exported to Photos, Files, or a social platform separately. Manage or cancel subscriptions through the provider that billed you.
6. Your Choices and Rights
You may manage notification and device permissions in your device settings. Changing a permission affects future access. To request access to or deletion of information already collected, or ask about our processing, contact us below.
7. Security and Contact
We use reasonable technical and organizational safeguards, but no method of transmission or storage is completely secure. For privacy questions or requests, email devk@loshitech.com.
