Auren creates an anonymous installation identity on your device for online services such as translation, connected-provider narration, Gift a Listen, and support. The identifier and its 32-byte secret stay in ThisDeviceOnly Keychain storage. Auren stores only a hash of the secret and uses short-lived installation sessions. Auren Premium Voice sends each uncached passage through Auren's service for narration and tracks the period allowance. A Premium-only access token is stored in iOS Keychain. Premium audio is cached on the device and on Auren's service; private-import audio is owner-scoped. Optional connected-provider narration accepts an existing developer API key. For each uncached passage, Auren sends the provider key and passage through its Cloudflare service to the provider selected. Connected-provider audio is cached on the device. Auren does not create provider accounts or sell provider usage. Before translating an article, Auren asks for permission to send the article title and text through Auren's service on Cloudflare to Google Gemini. Do not continue with content you do not want processed off your device. Auren requires an Auren subscription for app access. In the US, Auren Monthly is $7.99 per month and includes about 75 minutes of Auren Premium Voice each month. Auren Annual is $59.99 per year and includes 15 hours of Auren Premium Voice each year.

Each plan renews automatically for its billing period unless canceled in your App Store account. Apple determines trial eligibility and shows the offer and price before purchase confirmation.
