Moderate risk. Suitable for internal data but avoid confidential information.
Sonix states it will not use audio/video files for purposes other than providing the service without express permission, but the Privacy Policy uses vague 'service improvement' language and mentions using aggregated/anonymized data. No explicit opt-out mechanism or clear prohibition on training is stated.
“[ToS] 'Unless you have given us your express permission, we will not use or share your audio and video files for any other purposes except to provide you with our transcription, translation, analysis, and other related services.' [Privacy] 'Sonix and its subsidiaries and affiliates may also use your Personal Data collected through the Services to help us improve the content and functionality of the Services.'”
The ToS grants Sonix a license to use content for service provision but language around sublicensing and scope is somewhat broad. The license appears tied to service delivery but lacks explicit termination language upon account deletion.
“[ToS] 'You acknowledge that Sonix does not pre-screen content, but that Sonix and its designees will have the right (but not the obligation) in their sole discretion to refuse or remove any content that is available via the Service.' No explicit license grant language found; license scope inferred from service use terms.”
Sonix shares data with 'Related Companies,' 'Agents, Consultants and Related Third Parties' for business functions, and mentions sharing aggregated data with 'affiliates, agents and business partners.' While some controls exist (only providing necessary information), the list of third parties is broad and sub-processor details are not fully transparent.
“[Privacy] 'Sonix, like many businesses, sometimes hires other companies to perform certain business-related functions...When we employ another entity to perform a function of this nature, we only provide them with the information that they need to perform their specific function.' [Privacy] 'Sonix may share this aggregate data with its affiliates, agents and business partners.'”
The Privacy Policy states retention is 'for the period necessary to fulfill the purposes outlined' but provides no specific timeframes. The ToS mentions Sonix may establish 'maximum period of time that data or other content will be retained' but does not specify what those periods are or guarantee prompt deletion.
“[Privacy] 'We will retain your Personal Data for the period necessary to fulfill the purposes outlined in this Privacy Notice unless a longer retention period is required or permitted by law.' [ToS] 'You acknowledge that Sonix may establish general practices and limits concerning use of the Service, including without limitation the maximum period of time that data or other content will be retained by the Service.'”
The ToS explicitly states that users own their User Content and Sonix does not claim ownership of outputs. The service is designed to provide transcription/translation outputs to the user, with no language suggesting Sonix retains rights to generated content.
“[ToS] 'Except as expressly authorized by Sonix, you agree not to modify, copy, frame, scrape, rent, lease, loan, sell, distribute or create derivative works based on the Service or the Service Content, in whole or in part, except that the foregoing does not apply to your own User Content (as defined below) that you legally upload to the Service.'”
The Privacy Policy mentions 'Standard Contractual Clauses regarding EU data protection' and references GDPR compliance, but no SOC 2, ISO 27001, HIPAA, or other formal certifications are explicitly stated. A security page is referenced but not detailed in the provided documents.
“[Privacy] 'Refer to Standard Contractual Clauses regarding EU data protection.' [ToS] 'Your access to and use of the Services is subject to the Terms of Service at www.sonix.ai/terms' with reference to security practices, but no specific certifications listed in provided documents.”
