Both programs were built to work on your own Mac, so your work stays yours. Here is exactly what happens.

Stays on your Mac, always: your recordings, documents, voices, handwriting examples and settings. Speech recognition and handwriting reading run entirely on your Mac.
Only these things use the internet:
| Downloading the speech model | Once, from Hugging Face (the model's publisher). Nothing about you or your work is sent. Or import an offline model pack instead. |
|---|---|
| Your licence | When you activate, and about once a day after that, the program sends your licence key and a code for this computer (a one-way fingerprint, not your Mac's serial number) to our licence server. Never documents or recordings. |
| Checking for updates | Once a day the program asks our server for the newest version number. Nothing about you is sent. |
| AI Editor (only if you use it) | Only when you press Edit, the text of the document (or the part you selected) is sent to the service you chose — Anthropic (Claude) or OpenAI — using your own account and key. Recordings are never sent. Your key is kept in your Mac's Keychain. |
| Contact support | Prepares an email for you to read and send yourself. It contains what you write, the program and macOS version and which models are installed, plus a picture of the program only if you leave that ticked. Your document text is never added. |
What our licence server keeps: your name and email (to send your key), your licence key in scrambled form, the computer codes of the Macs you activated, and when each last checked in. Nothing else.
No analytics, no tracking, no adverts.
Seforim Library
No personal data is collected. The app has no account, no sign-in, no analytics, no tracking and no adverts.
No internet connection is used. Your seforim, notes, bookmarks, reading progress and learning history are never uploaded anywhere. Everything stays on your Mac — in the library folder you choose, and in the backup copies you control. Text recognition and searching inside your seforim run entirely on your Mac.

Emails
We never sell, share or see your information from the programs, because we never receive it. If you email us, we use your address only to reply to you, and we don't add it to any mailing list.
