Privacy Policy

Last updated: October 27, 2026

The short version

SuprFlow turns your speech into text on your own computer, with a speech model you download. Your audio is never sent to us. If you turn on cloud formatting, the transcript text goes to the provider you choose. SuprFlow also uses the network for sign-in and licence checks, model downloads, updates and usage analytics, which are described below.

Where dictated content goes

Speech recognition and the default text cleanup run on your computer, on Mac, Windows and Linux. Other features have their own data paths:

  • Audio is transcribed on your computer. It is not uploaded.
  • Recordings are saved on your computer with your transcription history, so you can play them back or transcribe them again. By default SuprFlow keeps a recording for each entry in your history (the last 100). You can keep them for a shorter time or not at all in Settings > Advanced.
  • Transcript text is sent to an external provider only if you turn on cloud formatting. It goes to the provider or endpoint you choose (for example OpenAI, Anthropic, Google Gemini, xAI, DeepSeek, Mistral, Groq, OpenRouter, Z.AI, Cerebras, Amazon Bedrock or a custom endpoint), together with the formatting instructions. That provider's own privacy terms apply. An Ollama endpoint you set up may also be on another computer. Apple Intelligence formats on your Mac.
  • The app you're dictating into. To pick a formatting mode automatically, SuprFlow reads the name of the app you're dictating into and its window title. On Mac it can also read the website address in your browser and the label of the text field. This stays on your computer and isn't sent to formatting providers.
  • History keeps raw, cleaned and formatted transcripts on your computer. Pasting text can briefly use the system clipboard, where another clipboard manager may keep a copy.
  • Clipboard history keeps your last 100 copied texts and images on your computer. It's on by default; turn it off in Settings > General. On Mac, items that password managers mark as private are skipped.
  • Dictionary entries, snippets and settings are stored on your computer. API keys for formatting providers are kept in your system's secure credential store (Keychain on Mac, Credential Manager on Windows, Secret Service on Linux).
  • Text you dictate into another app is then handled by that app, which may sync it elsewhere.

Usage analytics

SuprFlow sends usage analytics to TelemetryDeck to help us understand how the app is used and fix problems. This is on in every release and can't be turned off in the app. Each event includes:

  • an anonymous ID for your installation, which isn't linked to your account or email address;
  • the SuprFlow version, your operating system and its version, your processor type, and your language settings;
  • the event name (for example a dictation finishing or a setting changing), with counts, durations and size ranges, and error messages shortened to 100 characters.

Analytics never include your audio, your transcripts, your clipboard or the content of what you type.

What we do store

When you purchase or sign in to SuprFlow, we process account and licence information, including your email address. Each computer you sign in on is registered to your licence with a random device ID and the computer's name, which you can see in your account's device list. We use this information for:

  • License management: To validate your purchase, deliver your license key, and check your licence and device limit while you use the app.
  • Product updates: To notify you of new versions and important changes. You can opt out of these communications at any time.
  • Support: To respond if you contact us with questions or issues.

Contact support if you need the current list of service providers, retention periods, or account-data controls.

Payment processing

Payments are handled by a third-party payment processor. Its checkout collects the payment details needed to complete the purchase under its own privacy terms.

Network connections and offline use

Once a speech model is downloaded, speech recognition works without an internet connection. SuprFlow connects to the internet for:

  • signing in and checking your licence, which works offline for a limited grace period;
  • downloading speech models, from our download server or from Hugging Face;
  • checking for and downloading updates, from our download server;
  • usage analytics, as described above;
  • cloud formatting, if you turn it on.

Like any internet request, these connections reveal your IP address to the server you connect to.

Your rights

You have the right to:

  • Access the personal data we hold about you (your email address, licence and registered devices).
  • Correct any inaccurate information.
  • Delete your data. You can request that we permanently remove your email and all associated records from our systems.
  • Export your data in a portable format.

To exercise any of these rights, email us at [email protected]. We will respond within 30 days.

Children

SuprFlow is not directed at children under the age of 13. We do not knowingly collect personal information from children.

Changes to this policy

If we make meaningful changes to this policy, we will notify you by email before the changes take effect. Minor clarifications or formatting updates may be made without notice.
