“If you choose to give us any ideas, know-how, algorithms, code contributions, suggestions, enhancement requests, recommendations or any other feedback for our products or services (collectively, “Feedback”), you acknowledge and agree that GitHub will have a royalty-free, fully pa…”
Feedback provided during Beta Preview (which could include code, algorithms, or technical know-how) is subject to an extremely broad, irrevocable, perpetual, sublicensable, commercially exploitable license with no compensation to the user.
“ If greater rights are needed, a mutually acceptable written addendum specifically conveying such rights must be included in these Terms. These Terms are effective and were last updated on Jul 1, 2025. Speechify, Inc. is located at 382 NE 191st St PMB 69469, Miami, FL, 33179-38…”
“ GitHub and our licensors, vendors, agents, and/or our content providers retain ownership of all intellectual property rights of any kind related to the Website and Service. We reserve all rights that are not expressly granted to you under this Agreement or by law. The look and f…”
“by submitting User Material you hereby grant Speechify an irrevocable, perpetual, non-exclusive, royalty free, worldwide license to use, telecast, copy, perform, display, edit, distribute and otherwise exploit the User Material you post on the Services, or any portion thereof, an…”
Irrevocable, perpetual, royalty-free license covering commercial, promotional, and advertising use with sublicensing rights through multiple tiers and no attribution requirement. This is an extremely broad license-back on user-submitted content.
“In addition, for Individual subscribers only: GitHub may use Copilot interaction data — including prompts (inputs), s uggestions (outputs), and code snippets generated during Copilot sessions — to train and improve AI models. This training helps improve code suggestions for all C…”
Individual (Free/Pro/Pro+) subscribers' prompts, outputs, and code snippets are used for AI model training by default. Opt-out is available but must be actively exercised.
“by submitting User Material you hereby grant Speechify an irrevocable, perpetual, non-exclusive, royalty free, worldwide license to use, telecast, copy, perform, display, edit, distribute and otherwise exploit the User Material you post on the Services, or any portion thereof, an…”
The license is broad enough to potentially encompass model training (use 'in any manner'), but training is not explicitly mentioned. Users cannot be certain their submissions will not be used for AI/ML training purposes.
“It is your responsibility to assess what is appropriate for the situation and implement appropriate safeguards.”
The document places responsibility for assessing appropriateness of use entirely on the user but does not explicitly restrict or permit commercial use of outputs. No affirmative commercial use restriction or permission is stated.
“in any manner (including, without limitation, for commercial, publicity, trade, promotional, or advertising purposes) and in any and all media now known or hereafter devised, and to prepare derivative works of, or incorporate into other works, such User Material, and to grant and…”
Speechify can commercially exploit user-submitted content for advertising and promotional purposes without compensation. This restricts the user's exclusive commercial value in their own submitted material.
“GitHub and third parties use social media cookies to show you ads and content based on your social media profiles and activity on GitHub’s websites. This ensures that the ads and content you see on our websites and on social media will better reflect your interests. This also ena…”
Third parties can use data collected on GitHub to improve their own products on entirely separate websites, extending data use well beyond the GitHub platform context.
“Please note that your continued use of Speechify after any change means that you agree with and consent to be bound by the new Policy. If you disagree with any changes in this Policy and do not wish your information to be subject to it, you will need to delete your Speechify acco…”
Continued use constitutes consent to updated privacy terms. Users who disagree must delete their account—there is no mechanism to object to specific changes while retaining service access.
“When a school or employer supplies your GitHub account, they assume the role of Data Controller for most Personal Data used in our Services. This enables them to: Manage and administer your GitHub account, including adjusting privacy settings. Access and utilize your Person…”
Users on organization-provisioned accounts have significantly reduced privacy protections — their employer or school can access content, files, and usage data and adjust privacy settings.
“Application of Consumer Law to Business Users Speechify’s Business, Enterprise, Studio, Voice-Over, and API offerings are intended for commercial use. To the maximum extent permitted by law, Business Users acknowledge and agree that consumer-protection statutes and implied war…”
Business, Enterprise, API, and Studio users explicitly waive consumer-protection statutes and implied warranties, materially reducing their legal recourse.
