Start here. These are the highest-risk verified clauses AIRIN found in the platform's own policy text.
Blanket consent-by-submission is a weak legal basis under GDPR/PIPL. Absence of named transfer mechanisms increases compliance risk for EU/EEA and other regulated-jurisdiction users.
The acknowledgment of national-security disclosure combined with vague transfer safeguards ('in accordance with applicable law') is a material risk for EU-based users relying on GDPR protections.
This clause restricts users from uploading any data subject to third-party confidentiality obligations and expressly disclaims Stack AI's liability for such data. The risk shifts entirely to the user, who could face breach-of-contract claims from third parties if they violate this provision.

This clause imposes significant restrictions on the categories of sensitive data that can be processed, covering major US regulatory frameworks. The complete liability disclaimer for prohibited data transfers full legal and regulatory risk to the user. Enterprise/self-hosted options are carved out as compliant pathways, indicating a tier difference for regulated data handling.

The liability cap limits platform exposure to fees paid in the prior 6 months — potentially a very small sum for low-volume users. Complete exclusion of consequential, punitive, and incidental damages means users cannot recover for data loss, lost profits, or business disruption. Simultaneously, the user must indemnify the platform for claims arising from any use of the service. This creates a strongly asymmetric risk profile.
"Stack AI shall have no liability for any loss, damage, or injury resulting from your or any third parties' negligence, lack of training, use or misuse, or misapplication of any Product or Service. You agree to indemnify, defend, and hold h..."
Clause B explicitly excludes the user's indemnification obligation for data loss, misuse, or disclosure resulting from the platform's misconduct or gross negligence, while Clause A does not include such an exclusion for claims related to 'Your Information' or third-party privacy rights, creating an opposing obligation.
" You agree to defend, indemnify and hold harmless Stack AI, its affiliates, officers, directors, employees and agents from and against any and all claims, damages, obligations, losses, liabilities, costs or debt, and expenses (including but not limited to attorney’s fees) arising from: (i) your use of and access to the Stack AI Site or Service; (ii) your violation of any term of these Terms of Use; (iii) your violation of any third- party right, including without limitation any copyright, property, or privacy right; or (iv) any claim that any of Your Information caused damage to a third party. This defense and indemnification obligation will survive these Terms and your use of the Stack AI Site. You hereby agree to waive the application of any law that may limit the efficacy of the foregoing agreement to defend and indemnify Stack AI and its affiliates, officers, directors, employees and agents."
" G. Your Indemnification of Us . You will defend and indemnify us from and against any losses, liabilities, damages, demands, suits, causes of action, judgments, costs or expenses (including court costs and reasonable attorneys' fees) arising out of or relating to (1) a breach of these Terms by you or any Authorized User; (2) the intellectual property rights in any of your Customer Data; (3) any loss, misuse, or disclosure of Customer Data not the result of our misconduct or gross negligence; and (4) any other claim relating to any classified or personally identifiable information within Customer Data, where such personally identifiable information (A) identifies or can be used to identify an individual, such as first and last name, social security number or other government issued number or identifier, date of birth, home or other physical address, e-mail address or other online contact information, telephone number, biometric data, mother’s maiden name, or other personally identifiable information; or (B) includes any “non-public personal information” as that term is defined in the Gramm-Leach-Bliley Act found at 15 U.S.C. Subchapter 1, §6809(4)."
Within one documentClause A permits sharing credentials with 'Authorized Users' under specific conditions, while Clause B imposes absolute liability on the user for any access by any person to whom credentials were provided, including those 'Authorized Users,' thereby negating the limited permission granted in Clause A.
"C. You Have Security Responsibilities. You agree to: (i) keep your password and online ID secure and strictly confidential, providing it only to Authorized Users of your account; (ii) instruct each person to whom you give your online ID and password that he or she is not to disclose it to any unauthorized person; (iii) notify us immediately and select a new online ID and password if you believe your password may have become known to an unauthorized person; and (iv) notify us immediately if you are contacted by anyone requesting your online ID and password. When you give someone your online ID and online password, you are authorizing that person to access and use your account, and you are responsible for any and all transactions that person performs while using your account, even those transactions that are fraudulent or that you did not intend or want performed. You agree to indemnify and hold harmless Stack AI from and against any and all liability arising in any way from the access to the Site by persons to whom you have provided your online ID and/or online password. In addition, you are responsible for your information technology infrastructure, including computers, servers, software, databases, electronic systems (including database management systems) and networks, whether operated directly by you or through the use of third-party services. You agree to abide by all applicable local, state, national, and international laws and regulations in connection with using the Product, Documentation and Service, including, without limitation, all laws regarding the transmission of technical data exported from the United States through the Service and all privacy and data protection laws, rules and regulations."
"You agree to indemnify and hold harmless Stack AI from and against any and all liability arising in any way from the access to the Site by persons to whom you have provided your online ID and/or online password."
Within one documentClause B explicitly excludes user indemnification for data loss, misuse, or disclosure resulting from Stack AI's misconduct or gross negligence, while Clause A contains no such exception and its broad language could imply indemnification regardless of Stack AI's fault.
" You agree to defend, indemnify and hold harmless Stack AI, its affiliates, officers, directors, employees and agents from and against any and all claims, damages, obligations, losses, liabilities, costs or debt, and expenses (including but not limited to attorney’s fees) arising from: (i) your use of and access to the Stack AI Site or Service; (ii) your violation of any term of these Terms of Use; (iii) your violation of any third- party right, including without limitation any copyright, property, or privacy right; or (iv) any claim that any of Your Information caused damage to a third party. This defense and indemnification obligation will survive these Terms and your use of the Stack AI Site. You hereby agree to waive the application of any law that may limit the efficacy of the foregoing agreement to defend and indemnify Stack AI and its affiliates, officers, directors, employees and agents."
"You will defend and indemnify us from and against any losses, liabilities, damages, demands, suits, causes of action, judgments, costs or expenses (including court costs and reasonable attorneys' fees) arising out of or relating to (1) a breach of these Terms by you or any Authorized User; (2) the intellectual property rights in any of your Customer Data; (3) any loss, misuse, or disclosure of Customer Data not the result of our misconduct or gross negligence; and (4) any other claim relating to any classified or personally identifiable information within Customer Data, where such personally identifiable information (A) identifies or can be used to identify an individual, such as first and last name, social security number or other government issued number or identifier, date of birth, home or other physical address, e-mail address or other online contact information, telephone number, biometric data, mother’s maiden name, or other personally identifiable information; or (B) includes any “non-public personal information” as that term is defined in the Gramm-Leach-Bliley Act found at 15 U.S.C. Subchapter 1, §6809(4)."

" H. Usage Limitations. Your Subscription may be subject to Usage Limitations. Usage Limitations may include (among other things) a description of the specific product or service licensed from us, a maximum number of Authorized Users, the initial term of your Subscription, the fees you agree to pay us, a maximum amount of allotted storage, or other limitations. Usage Limitations applicable to your Subscription are set forth in our Product offerings on our pricing page. If your use of our Services exceeds a Usage Limitation or otherwise requires the payment of additional fees, you shall be billed for such usage and you agree to pay the additional fees."
Defines Usage Limitations that cap the scope of the subscription (number of users, storage, term, fees) and imposes an obligation to pay additional fees if usage exceeds those limits, creating enforceable tier-based usage restrictions.
AI-generated interpretation, not legal advice.
"ii. Personal Data. Despite anything to the contrary in these Terms, you shall not upload or provide to Stack AI any sensitive data including, without limitation: (1) protected health information regulated under HIPAA or HITECH; (2) cardholder data as defined under PCI DSS; or (3) nonpublic personal information ("NPI") as defined under the Gramm-Leach-Bliley Act (GLBA), which generally includes financial information provided by consumers to financial institutions. For clarity, general contact information such as email addresses, names, and phone numbers, when not combined with sensitive financial or health information, are not considered NPI under this policy. STACK AI expressly disclaims all liability with respect to any prohibited data. For processing sensitive data, customers are advised to use either the Enterprise version of Stack AI—certified for SOC 2 Type II compliance—or the self-hosted deployment option."
This clause imposes significant restrictions on the categories of sensitive data that can be processed, covering major US regulatory frameworks. The complete liability disclaimer for prohibited data transfers full legal and regulatory risk to the user. Enterprise/self-hosted options are carved out as compliant pathways, indicating a tier difference for regulated data handling.
AI-generated interpretation, not legal advice.
"We retain your Personal Information for as long as we need to fulfill our Services. In addition, we retain Personal Information after we cease providing Services to you, to the extent necessary to comply with our legal obligations. Where we retain data, we do so in accordance with any limitation periods and records retention obligations that are imposed by applicable law."
Absence of defined retention windows is a GDPR Article 5(1)(e) storage-limitation concern and generally leaves users unable to predict when their data will be deleted.
AI-generated interpretation, not legal advice.
"If you enable a public sharing of your Stack AI applications, any information or content that you voluntarily disclose in your application becomes available to the public. If you remove information that you posted to the Services, copies may remain viewable in cached and archived pages of the Service, or if other users of the Services have copied or saved that information."
Users who inadvertently include personal data in publicly shared applications lose practical control over that data; cached copies may persist indefinitely.
AI-generated interpretation, not legal advice.
"We regularly back up the database used in conjunction with the Services. We will make a commercially reasonable effort to assist in restoring lost data; however, we do not guarantee that every backup will complete without error, that we will be able to restore any specific data, or that we will retain any backup for longer than thirty (30) days."
The clause caps backup retention at 30 days and disclaims any guarantee of successful backup or restoration. There is no statement about how long live Customer Data is retained after termination, creating ambiguity about post-termination data handling.
AI-generated interpretation, not legal advice.
"If you choose to remove your Personal Information, you acknowledge that we may retain archived copies of your Personal Information in order to satisfy our legal obligations, or where we reasonably believe that we have a legitimate reason to do so."
The phrase 'where we reasonably believe that we have a legitimate reason' is a unilaterally defined exception that could be invoked broadly, undermining GDPR Article 17 erasure rights.
AI-generated interpretation, not legal advice.
"Stack AI shall have no liability for any loss, damage, or injury resulting from your or any third parties' negligence, lack of training, use or misuse, or misapplication of any Product or Service. You agree to indemnify, defend, and hold harmless Stack AI and its employees from any claims, damages and actions of any kind or nature arising from or caused by the use or misuse of any Service. IN NO EVENT WILL STACK AI BE LIABLE TO YOU OR TO ANY THIRD PARTY FOR ANY INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF USE, DATA, BUSINESS OR PROFITS) OR FOR COSTS OF PROCURING SUBSTITUTE SERVICES, ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT, THE SERVICES, THE SITE, OR ANY RESEARCH OR EXPERIMENT OR OTHER WORK PERFORMED USING ANY PRODUCTS OR SERVICES PURCHASED THROUGH THE SITE, HOWEVER CAUSED AND REGARDLESS OF THE THEORY OF LIABILITY, EVEN IF STACK AI HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. STACK AI'S TOTAL LIABILITY TO YOU, FROM ALL CAUSES OF ACTION AND ALL THEORIES OF LIABILITY, WILL BE LIMITED TO AND WILL NOT EXCEED THE AMOUNTS PAID TO STACK AI BY YOU UNDER THESE TERMS IN THE SIX (6) MONTH PERIOD IMMEDIATELY PRECEDING ANY CLAIM MADE UNDER THIS AGREEMENT."
The liability cap limits platform exposure to fees paid in the prior 6 months — potentially a very small sum for low-volume users. Complete exclusion of consequential, punitive, and incidental damages means users cannot recover for data loss, lost profits, or business disruption. Simultaneously, the user must indemnify the platform for claims arising from any use of the service. This creates a strongly asymmetric risk profile.
AI-generated interpretation, not legal advice.
"i. Confidential Information of Third Parties. Despite anything to the contrary in these Terms, under no circumstances will you upload to the Site or otherwise provide to Stack AI any data or information (including but not limited to third-party product or pricing information) which you are restricted from disclosing pursuant to any confidentiality (or similar) agreement with any third party. STACK AI EXPRESSLY DISCLAIMS ALL LIABILITY WITH RESPECT TO ANY SUCH THIRD PARTY CONFIDENTIAL INFORMATION."
This clause restricts users from uploading any data subject to third-party confidentiality obligations and expressly disclaims Stack AI's liability for such data. The risk shifts entirely to the user, who could face breach-of-contract claims from third parties if they violate this provision.
AI-generated interpretation, not legal advice.
"We may also release your Personal Information when we believe release is appropriate to comply with the law, enforce our site policies, or protect our or others’ rights, property, or safety. In particular, we may release your Personal Information to third parties as required to (i) satisfy any applicable law, regulation, subpoena/court order, legal process or other government request, (ii) enforce our Terms of Service, including the investigation of potential violations thereof, (iii) investigate and defend ourselves against any third party claims or allegations, (iv) protect against harm to the rights, property or safety of Stack AI, its users or the public as required or permitted by law and (v) detect, prevent or otherwise address criminal (including fraud or stalking), security or technical issues."
Items (ii) and (iii) go beyond pure legal compliance and allow disclosure in service of the platform's own enforcement and litigation interests, which is a notable user risk.
AI-generated interpretation, not legal advice.
"D. Some Third Parties May have Incidental Access to Your Information. Stack AI works with other companies to provide information technology services to users of the Site. These companies may have access to Stack AI's databases, but only for the purposes of providing service to Stack AI. For example, a third party (such as AWS) may obtain access to Your Information in an effort to update database software. These companies will operate under consumer confidentiality agreements with Stack AI."
The clause acknowledges subprocessor access to databases containing user data. While it states access is limited to service provision and covered by confidentiality agreements, it does not enumerate subprocessors, specify the terms of those agreements, or provide user rights to object or audit, which are relevant enterprise risk considerations.
AI-generated interpretation, not legal advice.
"We cooperate with government and law enforcement officials or private parties to enforce and comply with the law. We may disclose your Personal Information to government or law enforcement officials or private parties as we believe necessary or appropriate: (i) to respond to claims, legal process (including subpoenas); (ii) to protect our property, rights and safety and the property, rights and safety of a third party or the public in general; and (iii) to stop any activity that we consider illegal, unethical or legally actionable activity."
The inclusion of 'private parties' and voluntary disclosure for 'unethical' activity (beyond legal compulsion) represents a broader disclosure right than strictly necessary. The standard 'as we believe necessary or appropriate' is subjective and user-unfavorable.
AI-generated interpretation, not legal advice.
"We may share your Personal Information with other companies owned by or under common ownership as Stack AI, which also includes our subsidiaries (i.e., any organization we own or control). These companies will use your Personal Information in the same way as we can under this Privacy Policy, unless otherwise specified."
Intra-group sharing without additional consent or restriction expands the effective data exposure surface. Users cannot easily identify or control which affiliated entities receive their data.
AI-generated interpretation, not legal advice.
" Except as set out below, we do not sell, trade, or otherwise transfer to outside parties your Personal Information. We may share your Personal Information with other companies owned by or under common ownership as Stack AI, which also includes our subsidiaries (i.e., any organization we own or control)."
Establishes a general restriction against selling, trading, or transferring personal information to outside parties, while permitting sharing with affiliated companies under common ownership or control.
AI-generated interpretation, not legal advice.
"In the event that we enter into, or intend to enter into, a transaction that alters the structure of our business, such as a merger, reorganization, joint venture, assignment, sale, or change of ownership, we may share Personal Information for the purpose of facilitating and completing the transaction."
Standard but consequential clause: data can flow to a new corporate owner whose privacy practices may differ materially, with no guaranteed user notification or deletion right triggered.
AI-generated interpretation, not legal advice.
"Personal Information may be stored and processed in any country where we have operations, or where we engage service providers. This means that we may collect your Personal Information from, transfer it to, and store and process it in the United States and other countries outside of where you live. For example, some of our third-party providers may be located in different countries. Where this is the case, we will take steps to make sure the right security measures are taken so that your privacy rights continue to be protected as outlined in this Privacy Policy. By submitting your Personal Information, you’re agreeing to this transfer, storing or processing."
Blanket consent-by-submission is a weak legal basis under GDPR/PIPL. Absence of named transfer mechanisms increases compliance risk for EU/EEA and other regulated-jurisdiction users.
AI-generated interpretation, not legal advice.
"If you are located in the European Union or other regions with laws governing data collection and use that may differ from U.S. law, please note that we may transfer information, including Personal Information, to a country and jurisdiction that does not have the same data protection laws as your jurisdiction. If we transfer your Personal Information from the E.U. and process it in the United States, we do so in accordance with applicable law. In certain situations, we may be required to disclose personal information in response to lawful requests by public authorities, including to meet national security or law enforcement requirements."
The acknowledgment of national-security disclosure combined with vague transfer safeguards ('in accordance with applicable law') is a material risk for EU-based users relying on GDPR protections.
AI-generated interpretation, not legal advice.
" We may collect information you post to, or collect from, users of the Services. We use this information to operate, maintain, and provide to you the features and functionality of the Services."
Grants Stack AI permission to collect information posted to or collected from users of the Services and expressly states the purpose—to operate, maintain, and provide features and functionality of the Services—establishing a lawful use basis for this data category.
AI-generated interpretation, not legal advice.
" We may also use Personal Information you provide to send you email marketing about Stack AI products and services, invite you to participate in events or surveys, or otherwise communicate with you for marketing purposes. We allow you to opt-out from receiving marketing communications from us as described in the "Your Choices" section below."
Permits use of personal information for email marketing about Stack AI products, event invitations, and surveys, while also granting users the right to opt out of such communications.
