Facts

Price: Free tier

Add-on risk: Add-ons may have unrestricted functionality and access to information, so users should trust the developer before installing.
Add-ons: Community and third-party add-ons can add or change functionality, but NV Access does not vet them.
Certification: NV Access says it does not require ISO 27001 or SOC 2 certification because NVDA does not require registration or a license and it does not identify users.
Data handling: NV Access says information NVDA reads is not saved or sent anywhere.
Language reach: Volunteers have translated NVDA into more than 55 languages, and it has been used in more than 175 countries.
Legacy support: Older NVDA releases are provided for certain earlier Windows versions, but NV Access does not recommend or support running them on newer operating systems.
Open source: NVDA is open-source software, with code available to anyone.
Operating system: The current NVDA download is available for PCs running Windows 10 and later.
Privacy: NVDA does not collect personally identifiable information; limited information used to check for updates can be disabled.
Security controls: By default, NVDA allows custom add-ons that can execute arbitrary code, including when NVDA is elevated to administrator privileges.
Support: Corporate users can access telephone or online support and training material.
