Scope and responsible company
This notice covers MIXEL PDF for macOS in its Mac App Store or TestFlight distribution, Windows in its Microsoft Store MSIX distribution, and Linux in its desktop package distributions. It describes this desktop app version; other products and future SaaS or cloud services require their own applicable notices.
Mixel IT and Corporate Services GmbH provides these apps. For support or privacy questions, email info@mixel.ch or use the company contact page.
Your documents on your device
Open a local PDF, read or organize it, add supported annotations or edits and save a PDF copy. The app handles the document contents needed for those operations on your device.
Opening, editing, saving and exporting through these local workflows does not send the document contents to MIXEL. The app can store local settings, previews and recovery information as part of its operation. If you select an iCloud Drive, OneDrive or other synchronized folder, the provider and your settings control that synchronization.
Optional downloads and web links
Web links you choose use your browser. Their destination sites receive those connections and apply their own privacy notices. A web or email address requested by a PDF link, button or script is shown for your confirmation before opening. Such an address can contain document information or values entered in a form; review it before approving.
The app does not contact another website to check for updates. Use the update controls for the store or package channel from which you installed the app.
Mac: optional internet, devices and on-device features
The Mac app connects to the internet only for features you switch on in Settings ▸ Internet. All of them are off when the app is installed. When you switch one on, it contacts only the service named here, and only when you use the feature:
- Signature timestamps: a fingerprint (hash) of the signature is sent to the timestamp server you enter. The document itself is not sent.
- Certificate checks: the serial numbers and issuers of the certificates in a signature you check are sent to the revocation servers those certificates name.
- Trusted lists: the app downloads the European list of trusted lists, or a trust list from an address you enter. Nothing from your documents is sent.
- Directory lookup: the name or email address you search for is sent to the directory server you enter, to find a recipient’s certificate.
- Remote signature service: you sign in with the provider you configure; the fingerprint of the document to be signed is sent to that provider, under its own privacy notice.
- Web page to PDF: the app loads the web address you enter, like a browser.
- Form submission: when a form sends its data to a web address, the app shows the address and sends the form data only after you confirm.
Microphone: used only while you record an audio comment, after macOS asks for your permission. The recording is stored in the PDF you save. Scanners and cameras: used only when you scan or import from an iPhone or iPad; the images go into your document.
Scripts in PDFs run on your Mac in a sandbox without internet, file or app access, and can be switched off in Settings. Text recognition, translation, summaries, suggestions and charts use Apple’s on-device frameworks; your documents are not sent to MIXEL or to another AI service. Handoff, when you use it, passes the open document and page to your other Apple devices through your Apple Account.
Files and permissions you control
Use the app’s file and folder dialogs to choose what to open and where to save or export. You can cancel a dialog. Your operating system controls the permissions available to the app. Exported files can contain the content and metadata you retain; inspect them before sharing.
Windows and Linux builds have an optional local automation interface that is off unless you enable it at launch. It listens on this device rather than on a MIXEL cloud service. Connected local tools can inspect and control the app and obtain data exposed by that interface; enable it only for tools you trust.
Voluntary support and privacy questions
If you contact us, you choose the message, reply address and attachments to provide. We use that information to respond to your request. Sharing a sample document or diagnostic file is optional. The company privacy policy covers website and voluntary contact handling separately.
Other notices
Copyright and third-party licence notices supplied with the app remain applicable. Optional downloaded models or datasets have their own terms and notices. This page does not replace them. Future versions that change data handling require an updated notice.
