Terms of Service

Last updated: October 26, 2026

What you are buying

SuprFlow is a voice-to-text application for macOS, Windows and Linux. When you purchase SuprFlow, you receive a perpetual, non-exclusive license to use the software on your personal devices. This is a one-time purchase. There are no subscriptions, recurring fees, or usage limits.

License

  • Your license is personal and tied to your email address.
  • You may install and use SuprFlow on up to 5 devices that you personally own.
  • You may not redistribute, resell, sublicense, or share your license key with others.
  • You may not reverse-engineer, decompile, or modify the application.

Updates

Your purchase includes lifetime free updates. All future versions of SuprFlow will be available to you at no additional cost. We reserve the right to change what constitutes a “major version” in the future, but as of today, all updates are included.

System requirements

SuprFlow requires macOS 12 or later (Apple Silicon or Intel), Windows 10 or 11 (64-bit), or 64-bit x86 Linux. You will need approximately 1 GB of free disk space and an internet connection for the initial download of the app and the default speech model (about 300 MB); larger speech models need more space. It is your responsibility to verify that your system meets these requirements before purchasing. We clearly state these requirements on our system requirements page and download page.

Refunds

We offer a 7-day no-questions-asked refund on your first purchase. Not satisfied? Contact us within 7 days and we'll issue a full refund.

The refund policy applies for the first purchase only.

Contact [email protected] to request a refund.

Privacy and data

Built-in speech recognition and default text cleanup run on your Mac. Optional Cloud API formatting sends transcript text and formatting instructions to the provider you select. Local history, clipboard insertion, account and license checks, and telemetry have separate data paths. For full details, see our Privacy Policy.

Availability and support

SuprFlow is a locally installed application. A downloaded speech model can recognize voice on your Mac, while setup, account and license checks, updates, and optional hosted formatting may require a connection. Check the current signed release before depending on an offline workflow. We provide support via email on a best-effort basis.

Disclaimer

SuprFlow is provided “as is” without warranty of any kind, express or implied. Voice recognition accuracy depends on factors including microphone quality, background noise, accent, and language. We do not guarantee perfect transcription in all conditions.

Limitation of liability

To the maximum extent permitted by law, SuprFlow and its creators shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the software. Our total liability is limited to the amount you paid for your license.

Third-party speech models

SuprFlow lets you download optional speech models made by third parties. Each model is provided under its own license, which the app shows before you download it and lists under Settings → About → Open-Source Licenses. By downloading or using a model, you agree to follow its license.

MedASR (Google). The MedASR model is provided under and subject to the Health AI Developer Foundations Terms of Use, and SuprFlow asks you to accept them before you download it. The following restrictions are part of these terms and are enforceable against you. If you download or use MedASR, you must not use it, or allow anyone else to use it:

  • for any of the restricted uses described in the Health AI Developer Foundations Prohibited Use Policy, as Google updates it from time to time, which is incorporated into these terms by reference;
  • for any use that could cause a health regulatory authority to deem Google to be a “manufacturer” of a medical device. SuprFlow is a dictation tool, not a medical device, and its transcripts must not be relied on to diagnose or treat anyone; or
  • in violation of applicable laws and regulations.

Under the Prohibited Use Policy, you must not use MedASR, or anything derived from it, to:

  • generate content that infringes, misappropriates or otherwise violates anyone’s rights, including rights in copyrighted content;
  • promote or generate content related to child sexual abuse or exploitation;
  • promote or facilitate the sale of, or provide instructions for synthesizing or accessing, illegal substances, goods or services;
  • facilitate or encourage anyone to commit any type of crime;
  • promote or generate violent extremism or terrorist content;
  • engage in the illegal or unlicensed practice of any vocation or profession, including legal, medical, accounting or financial practice;
  • abuse, harm, interfere with or disrupt services, or enable others to, such as by promoting or facilitating spam or generating content for deceptive or fraudulent activities, scams, phishing or malware;
  • attempt to override or circumvent safety filters, or intentionally drive the model to act in a way that contravenes the policy;
  • generate content that promotes or encourages hatred, harassment or bullying, violence or self-harm;
  • generate personally identifying information for distribution or other harms, or track or monitor people without their consent;
  • generate content that may have unfair or adverse impacts on people, particularly impacts related to sensitive or protected characteristics;
  • generate, gather, process or infer sensitive personal or private information about individuals without all rights, authorizations and consents required by applicable law;
  • misrepresent the provenance of generated content, such as claiming it was created by a human or is an original work, or impersonate an individual (living or dead) without explicit disclosure, in order to deceive;
  • make misleading claims of expertise or capability, particularly in sensitive areas such as health, finance, government services or law;
  • make automated decisions in domains that affect material or individual rights or well-being, such as finance, legal, employment, healthcare, housing, insurance and social welfare;
  • generate defamatory content; or
  • generate sexually explicit content, including content created for pornography or sexual gratification. This does not include content created for scientific, educational, documentary or artistic purposes.

This list is provided for convenience. Google’s current Prohibited Use Policy and Terms of Use govern if they differ from it.

Changes to these terms

We may update these terms from time to time. If we make material changes, we will notify you by email. Continued use of the app after changes constitutes acceptance of the new terms.
