Privacy Policy

OneSentence Privacy Policy Last Updated: December 23, 2025 1. Our Philosophy Your thoughts belong to you. OneSentence is built on Privacy by Architecture. We didn't just decide not to collect your data; we built a system that is unable to see it. 2. Scope of this Policy This policy covers the OneSentence macOS Application ("the Application") and the onesentence.app website, including its subdomains ("the Website"). 3. The OneSentence Application (100% Offline) The Application is a strictly local-first utility. - Zero Collection: The Application does not collect, store, or transmit your voice, text, or clipboard content. - No Cloud Uploads: The Application contains no networking code for user data transmission. All processing is 100% offline. - Local AI Processing: All AI inference (Whisper and Supertonic) occurs entirely on your Mac's hardware, utilizing the Apple Silicon Neural Engine. - Temporary Files: Audio recordings are held in temporary memory or a transient local file for the duration of transcription and are permanently deleted immediately afterward. - No Tracking: We do not use analytics, crash reporting SDKs, or any form of behavioral tracking within the Application binary. 4. The OneSentence Website & Feedback Form When you visit our Website or use our web-based Feedback Form, standard web protocols apply: - Feedback Submissions: If you choose to use the "Share Feedback" feature during uninstallation, the data you explicitly provide (rating and text) is transmitted to our Cloudflare-hosted backend and stored in a secure database. This data is not linked to your identity. - Web Logging: Like most websites, our server logs capture standard metadata provided by your browser, such as IP address and User-Agent, to help us detect bot abuse and understand system compatibility. - Cookies: Our Website does not use tracking or advertising cookies. 5. Data Security & Retention Feedback data is stored securely using Cloudflare D1 and is used exclusively for product improvement. We do not sell or share user data with third parties. 6. Your Rights Since we do not collect personal identifiers, we have no way to link specific data back to you.
