Privacy Policy

Blurtly is operated by KU LABS LLC (“Blurtly,” “we,” “us,” or “our”). This policy applies to the Blurtly mobile application, website, and related services.

Depending on how you use Blurtly, we may handle:

• Account information, such as your name, email address, account identifier, profile image, and sign-in method.
• Learning content, including words, phrases, stories, prompts, language choices, grammatical preferences, practice progress, and other content you choose to provide.
• Voice and transcription data. When you use speaking practice, microphone audio is transmitted for live speech recognition and converted into text so Blurtly can evaluate your response.
• Technical information, such as device and browser type, operating system, IP address, request times, and diagnostic or security information generated when you use the service.

Learning data and progress are stored locally on your device. For signed-in users, Blurtly also stores cloud-backup copies so progress can be recovered after reinstalling the app. Blurtly does not use your information for targeted advertising and does not sell your personal information.

We use information to:

• create and secure your account;
• generate personalized language exercises, explanations, translations, speech, and feedback;
• recognize speech and evaluate speaking practice;
• save your preferences and learning progress;
• operate, maintain, troubleshoot, and protect the service; and
• comply with legal obligations and enforce our Terms of Service.

Blurtly uses service providers to deliver core features. The information sent to each provider is limited to what is needed for that feature:

• Clerk provides authentication and account management, including email, Google, and Apple sign-in.
• OpenAI processes learning prompts and content to generate exercises, explanations, translations, and text-to-speech audio.
• Google Gemini processes microphone audio for real-time speech recognition and transcription.
• ElevenLabs generates teaching and pronunciation audio.
• Hosting and infrastructure providers process requests and technical information and store private backup copies needed to operate and secure the website, API, media delivery, and progress-recovery systems.

These providers process information for us under their applicable terms and data-protection commitments. We may also disclose information if required by law, to protect rights and safety, or as part of a merger, financing, acquisition, or sale of assets.

Blurtly only accesses your microphone after you grant system permission and begin a speaking feature. Audio is streamed to Google Gemini to provide transcription. Blurtly does not use microphone audio for advertising or to identify you by your voice.

You can deny or revoke microphone permission in your device settings. Features that require speaking will not work without microphone access, but you can continue using parts of the service that do not require it.

You can separately withdraw permission for AI and voice processing from Profile under Privacy controls. After withdrawal, Blurtly will not send new learning content or microphone audio to OpenAI or Google Gemini unless you choose to grant permission again.

We retain account information while your account is active and as reasonably necessary to provide the service, meet legal obligations, resolve disputes, prevent abuse, and enforce our agreements. Service providers may retain information according to their agreements with us and applicable law.

You can delete your Blurtly account from the account settings in the app. Account deletion removes the account and associated information from our active account systems, except information we must retain for legal, security, fraud-prevention, or other legitimate purposes. Deleting your account also removes that account’s cloud backups and locally stored learning data, progress, preferences, cached explanations, and AI-processing consent from the device. Deleting the app removes its local data; signing back into a fresh installation may restore data from the account’s cloud backup.

You can update certain profile details, withdraw AI and voice processing consent, change microphone permission, sign out, or delete your account from the app. Withdrawing AI and voice consent does not affect processing that already occurred before withdrawal. Depending on where you live, you may also have rights to access, correct, delete, restrict, or receive a copy of your personal information.

To make a privacy request, email contact@blurtly.to. We may need to verify your identity before completing a request.

We use reasonable administrative, technical, and organizational measures designed to protect information. No system is completely secure, so we cannot guarantee absolute security.

Blurtly and its providers may process information in countries other than the one where you live. Where required, we use appropriate safeguards for international transfers.

Blurtly is not directed to children under 13 for independent use, and we do not knowingly collect personal information from a child under 13 without appropriate authorization. If you believe a child has provided information improperly, contact us so we can investigate and take appropriate action.

We may update this policy as Blurtly changes. We will post the revised policy here and update the date above. If a change is material, we will provide additional notice when appropriate.

Questions or privacy requests can be sent to contact@blurtly.to.
