     <li><strong>Voice audio</strong> — captured only while you actively record. On a local engine, audio is transcribed on-device and raw audio is not uploaded. With a user-configured cloud engine, recordings are sent directly to that ASR provider. If you explicitly choose managed credits, recordings are sent through the OSGKeyboard managed gateway at <code>account.osglab.com</code> to the managed ASR provider for transcription. OSGKeyboard does not keep raw recordings after the request is processed.</li>
     <li><strong>Transcribed text and cursor context</strong> — after ASR, the transcript (not audio) may be sent for polish when you use a configured LLM or managed credits. A small amount of text around the cursor may be included to continue naturally. Secure fields are never captured, and cursor context is not written to logs or voice history. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>.</li>

Native speech and explicit user edits are used to infer recurring habits; historical prompts are supplied only to distinguish and remove AI-added style. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>.

Native speech and explicit user edits are used to infer recurring habits; historical prompts are supplied only to distinguish and remove AI-added style. The generated prompt is shown for review and is not saved or activated until you confirm it. When you later invoke a conversational clipboard-reply skill while a reviewed user-created style is active, that style prompt is sent with the copied text so the reply can follow your wording and rhythm; built-in polish personalities are not attached. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>.</li>
     <li><strong>AI mode questions</strong> — in AI keyboard mode, your spoken question text—or a question you tap from an idle suggestion—is sent to the selected AI service to generate an answer. User-configured requests go directly to that provider; managed-credit requests go through <code>account.osglab.com</code>. When the selected service supports server-side web search, it may retrieve public web results for time-sensitive answers.</li>
     <li><strong>Anonymous onboarding AI trial</strong> — before you sign in, onboarding can issue a short-lived, feature-limited credential after Apple App Attest verifies a genuine app installation. The four fixed lessons may send one voice transcript, an explicitly copied lesson sample for translation and reply, and one transcribed AI question through <code>account.osglab.com</code>. This flow does not create an account, process an Apple identity token, use credits, or upload raw voice audio. The copied lesson sample is temporary and does not enable or populate clipboard history. The service keeps only pseudonymous integrity, request-state, feature, and metering records needed to enforce the one-use limits and investigate abuse; it does not retain request or response bodies.</li>
     <li><strong>AI suggestions and OSGKeyboard web pages</strong> — the main app may request public suggestion titles from <code>key.osglab.com</code>; no voice, transcript, clipboard body, API key, or ordinary keystroke content is included. Opening the update page requests public content from <code>download.osglab.com</code>. Those hosts may process ordinary connection metadata such as IP address and request time.</li>
