Yes, for its ordinary paste path in SuprFlow 1.0.0. SuprFlow briefly places the final text on the macOS clipboard, simulates Command-V into the focused app, then tries to restore the previous clipboard string after about half a second. This makes insertion work in many apps, but the brief clipboard use matters if you dictate confidential material. SuprFlow's own clipboard-history setting is a separate feature; turning that feature off does not remove the ordinary paste step.
This answer describes SuprFlow 1.0.0; it is not a network or clipboard trace of every signed release. A live-stream mode has a different insertion path. Test the installed version and the destination app before relying on either behavior for a firm policy.
Follow a normal paste
The app saves the clipboard's existing plain string, clears the pasteboard, writes the final transcription, and sends Command-V. It then checks whether the clipboard changed in the meantime. If it did not, the app clears it and restores the saved string. If the user or another app changed the clipboard during that short period, SuprFlow leaves the newer value alone.
The restoration is best-effort. Because the app only saves a string representation, it may not preserve an earlier rich item such as an image, file, or formatted text. Another clipboard manager may observe the temporary transcription before SuprFlow restores anything. Apple also documents Universal Clipboard, which can make copied content available on nearby devices signed into the same Apple Account when its requirements are met. We have not verified whether a SuprFlow paste is captured by Universal Clipboard on every configuration; a sensitive-work assessment should test the actual devices and settings.
Two kinds of history to review
- Transcription history: SuprFlow stores recent raw, cleaned, and formatted text locally in its transcription-history file. Clearing the clipboard does not clear this store.
- SuprFlow clipboard history: The app has an optional clipboard manager that can persist text and image items in a separate file. In SuprFlow 1.0.0, a fresh install defaults that feature to enabled; check the switch on your own Mac. The insertion step synchronizes its clipboard change counter, apparently to prevent its own temporary paste from being added, but that does not control another clipboard app.
The destination app may then save or sync the pasted text independently. Treat these as separate locations in a retention review: temporary system clipboard, third-party clipboard tools, SuprFlow's two histories, destination document, and backups.
A safe five-minute check
Use a made-up sentence such as “North Pier account 042 is a test record” — never an actual client detail.
- In SuprFlow General settings, note whether Clipboard History is on. Record the installed SuprFlow and macOS versions.
- Copy a harmless image or rich-text sample in another app. Dictate the test sentence into the intended destination. Check whether the prior clipboard item survives. This probes the plain-string restoration limit without risking real data.
- With a separately approved clipboard manager, see whether it records the temporary sentence. If a firm prohibits clipboard capture, this needs an IT decision rather than assuming SuprFlow's own switch covers it.
- Check SuprFlow's transcription history and clipboard history separately. Then inspect the destination app's sync or version history.
- If the device uses Handoff or Universal Clipboard, test with a paired test device under the firm's policy. Record what you observed, not a universal conclusion.
If the normal paste path is unacceptable, ask for a verified insertion alternative for the exact target app and release. The app's live-stream mode uses Accessibility or keyboard simulation depending on the field, but it still needs testing for focus and correctness.
Questions people ask
Does switching off SuprFlow Clipboard History keep dictation off the clipboard?
No. The ordinary insertion method still places text on the system clipboard briefly to paste it. The setting controls SuprFlow's separate clipboard-history collection.
Does restoring the previous clipboard erase every copy?
No. Another clipboard manager may already have captured the temporary text; the destination app may save it; SuprFlow transcription history may retain it; and backups can hold older copies. Restoration also only preserves the prior plain string in SuprFlow 1.0.0.
Does SuprFlow send clipboard text to its AI formatter?
The formatter sends the current transcription text when Cloud API is selected. It does not appear to send the previous clipboard contents as part of that request. The destination's existing field context is captured separately through Accessibility; see the context guide for its current use and limits.
