Privacy Policy

Last updated: June 25, 2026

GlossOne is a native macOS app that transcribes speech and shows bilingual captions, using engines you choose yourself. GlossOne has no servers of its own, requires no account, and collects no personal data. This policy explains how your information is handled.

The short version

• Our App Store privacy label is Data Not Collected, matching the app's PrivacyInfo.xcprivacy manifest.
• We do not run any backend. GlossOne talks only to Apple and to the engines you set up.
• We do not collect, transmit, sell, or share your personal data.
• Speech recognition runs on-device, and translation can run on-device too. With those, your audio and text stay on your Mac entirely.
• If you choose a cloud translation engine or AI service (such as OpenAI, Claude, or Gemini), only the text you ask to translate is sent — directly from your Mac to that provider, and only after you opt in by selecting it and entering your own key.
• We tell you exactly what is sent and to whom before you enable a cloud engine, and we only integrate providers whose own privacy terms protect that data to a standard comparable to this policy.
• Your API keys and secrets are stored in the macOS Keychain on your device.
• There is no analytics, advertising, or third-party tracking in the app.

Information we collect

None. GlossOne does not have an account system and does not send your data to us. We have no analytics SDKs, no crash-reporting services, and no advertising. The developer of GlossOne never receives your audio, your transcripts, your credentials, or usage information.

App Store privacy label: Data Not Collected

On the App Store, GlossOne's privacy label is Data Not Collected. The app collects no data from you and no data is linked to your identity. This matches the app's privacy manifest, PrivacyInfo.xcprivacy, which declares no tracking (NSPrivacyTracking is false), no tracking domains, and an empty list of collected data types (NSPrivacyCollectedDataTypes). The manifest also declares the one required-reason system API GlossOne uses purely for its own on-device functionality — reading and writing the app's own settings (NSPrivacyAccessedAPICategoryUserDefaults, reason CA92.1: data accessible only to the app itself). Because GlossOne has no backend and no analytics, there is nothing for us to collect.

Audio, transcripts, and translations

GlossOne recognizes speech on your Mac on-device using WhisperKit, so the audio it listens to is processed locally and is not sent to us or to any third party. The audio is never uploaded anywhere for recognition.

When you translate a transcript, GlossOne sends only the text you ask to translate, directly from your Mac to the translation engine you have chosen. There is no relay or server of ours in between. When you choose Apple's on-device translator or a local model (for example via Ollama or LM Studio), the text is processed on your Mac or your own network and is not sent to any third party. The section below explains what happens when you choose a cloud engine.

Third-party translation and AI services

GlossOne can use third-party cloud services, including general translation providers and AI services, in two optional features: translating your live captions, and generating meeting notes from a transcript. To meet Apple's data-sharing requirements, here is exactly what that involves:

• What data is sent. For caption translation, only the specific text you ask GlossOne to translate (a transcript segment) is sent to the provider. For meeting notes, the transcript you choose to summarize is sent to the AI service you selected so it can generate the notes. Your audio is never sent — recognition happens on-device first. No account information, contacts, location, device identifiers, or other personal data are sent, because GlossOne does not have them.
• Who it is sent to. The text is sent only to the single engine you select, and directly to that provider — there is no relay of ours in between. GlossOne supports a range of engines: Apple's on-device translator (nothing leaves your Mac); dedicated translation services (such as DeepL, Google Cloud Translation, Microsoft Translator, Amazon Translate, Tencent, Baidu, Youdao, Alibaba, and Volcano Engine); and cloud AI services (such as OpenAI, Anthropic (Claude), Google (Gemini), DeepSeek, Moonshot (Kimi), Qwen, ERNIE, Hunyuan, Doubao, Groq, OpenRouter, Azure OpenAI, and other OpenAI-compatible cloud providers). Some engines — including Google Translate's free public endpoint and the cloud AI services above — send your text to a third-party server even when no API key is required. Separately, you can point GlossOne at an OpenAI-compatible model you run yourself via Ollama or LM Studio, in which case the text stays on your own machine or network. The authoritative, always-current list of engines is in the app under Settings ▸ Translation and Settings ▸ Summary, and GlossOne discloses what is sent and to whom before you enable each cloud engine.
• Your permission. The default engines run on-device, and nothing is sent to a cloud service unless you turn one on yourself. The first time you enable a cloud engine, GlossOne shows an in-app disclosure naming exactly what data will be sent and to which provider, and the engine activates only if you agree. You stay in control and can switch back to an on-device engine at any time.
• Equal protection. We only integrate established providers that publish their own privacy policies and that are contractually committed to protecting the data you send with safeguards comparable to those described in this policy. The handling of text you send to a cloud engine is also governed by that provider's own terms and privacy policy, linked below.

Privacy policies of some of the AI services, for example: OpenAI, Anthropic (Claude), Google (Gemini). For every other engine, please refer to that provider's own published privacy policy and terms.

Credentials and secrets

API keys, access tokens, and secrets you enter for your engines are stored in the macOS Keychain on your device. They are used only to authenticate requests to the engine they belong to and are never sent anywhere else. They are not transmitted to the developer.

Data stored on your device

GlossOne keeps your settings, transcription history, and diagnostic logs locally on your Mac, inside the app's sandbox container. This data stays on your device. If you turn on optional audio recording, the recordings are saved to a folder you choose and stay there. You can clear your history and remove all stored keys or reset all settings from the app's preferences.

Microphone

Transcribing your own voice uses macOS Microphone permission. GlossOne requests it only when you start a microphone session, and you grant it in System Settings. The microphone audio is processed on your Mac to produce the transcript; it is not recorded, stored, or sent to the developer. The one exception is the optional audio recording you can turn on yourself, which saves to a folder you choose and stays there on your Mac.

Screen Recording (system audio)

Capturing the audio playing on your Mac, or in a specific app such as a meeting in Zoom, uses Apple's ScreenCaptureKit, which macOS gates behind the Screen Recording permission. GlossOne uses this permission only to read the audio from the source you pick; it does not record or transmit what is shown on your screen. As with the microphone, the captured audio is processed on your Mac to produce the transcript and is never sent to the developer. The permission is requested only when you choose a system or app audio source, and you grant it in System Settings.

Purchases

GlossOne offers a 7-day free trial and a one-time purchase to unlock the app, handled entirely through Apple's StoreKit and the App Store. Apple processes the transaction; GlossOne does not receive or store your payment details. Purchase validation uses Apple-signed receipts on your device. Please see Apple's Privacy Policy for how Apple handles App Store transactions.

Model downloads

The first time you use on-device recognition, GlossOne downloads the speech model it needs. That download comes from the model's hosting provider and contains no personal data about you. After it is cached on your Mac, recognition runs locally.

Network connections

GlossOne makes network connections only to (1) the translation engines you configure, in order to perform the actions you request, (2) the host that serves the on-device speech model, to download it once, and (3) Apple, for App Store and in-app purchase functionality. It makes no other outbound connections. If you point an engine at a local server (for example Ollama or LM Studio), that connection stays on your own machine or network.

Children's privacy

GlossOne is not directed to children and does not knowingly collect any information from anyone, including children under 13.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new “Last updated” date.
