SUBSCRIPTION
Upon installing the Duos app, you will be able to practice one personalized mock interview for free. You will also receive full interview feedback and one debrief session with the AI coach. However, you won’t be able to access analytics or practice additional interviews without a subscription. If you like the app, consider subscribing.
Your subscription is set to auto-renew. You can change your subscription plan or turn off auto-renewal up to 24 hours before the renewal date in the settings of your Apple Account. When a subscription is cancelled, access to the app’s courses and features will expire at the end of the current payment period.
AUDIO TRANSCRIPTION AND USE OF TRANSCRIBED DATA IN AI MODELS
We send recorded audio from interviews and AI coach conversations to the Deepgram Speech-To-Text API to transcribe it into text. Deepgram is SOC 2 Type 2 certified and processes this data solely on our behalf, as a data processor.
This audio is not linked to any other personal data such as your email or account details.
Audio files are stored temporarily in Firebase Cloud Storage for up to 7 days and then automatically and permanently deleted.
The transcribed text from user-recorded audio, along with chat inputs and user-selected career information (e.g., role, skills, past experience), is used to simulate a personalized job interview experience.
This data is sent to Large Language Models (LLMs) hosted via Azure Foundry, an an enterprise-grade, isolated cloud environment. These models are not consumer-facing web services and have no runtime connection to external model providers.
No personally identifiable information (such as email) is transmitted to the LLMs. Only the username selected within the app is included for personalization.
Duos does not use any user data for AI model training and neither does the Microsoft environment we use.
