Nitro PDF is software for editing and electronically signing PDF files, from Nitro Software, Inc., which has an office in San Francisco. The Nitro PDF and Nitro Sign applications are installed as native desktop programs. Nitro Workspace adds a cloud hub that gives access to files from any device with an internet connection. According to the vendor, its AI processing runs in an encrypted Microsoft Azure environment.
The privacy policy of Nitro Software, Inc. lists an office in San Francisco, California, so the company is subject to US law, including the CLOUD Act. The website names no parent company. The policy refers to the GDPR and to certification under the EU-U.S. Data Privacy Framework, and states that personal data may be shared outside the EEA. It does not name hosting regions for customer data. The installed applications can be used on an organisation's own devices, but cloud features, AI processing and e-signature services need checks on data location, sub-processors and processing terms before use. The software is not open source.
