Terms of Use for ScreenStack

Last Updated: August 30, 2026

Welcome to ScreenStack. These Terms of Use ("Terms") are a legally binding agreement between you ("Customer," "you," or "your") and the company that owns and operates ScreenStack and screenstack.dev ("ScreenStack," "Company," "we," "our," or "us," including its successors and assigns). By clicking through, creating an account, purchasing an assessment, or otherwise using screenstack.dev or the services described below (the "Services"), you agree to be bound by these Terms, on behalf of yourself or the organization you are authorized to represent. If you do not agree with all of these Terms, do not use the Services.

If you are accepting these Terms on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms.

1. The Services

ScreenStack is a technical candidate assessment platform. A Customer purchases a single assessment, and we provision a private, time-limited assessment environment in which a candidate completes a defined coding task using a controlled AI tool. Upon completion, the Services generate an evaluation report (a "Scorecard") summarizing test outcomes, the candidate's final code diff, and the candidate's interactions with the AI tool. The Services are provided on a best-efforts basis for use in connection with Customer's own hiring and candidate evaluation processes, subject to the restrictions in these Terms.

2. Accounts

• You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account, including activity by your employees, agents, and other users you authorize.
• You must provide accurate and complete account information and keep it up to date.
• We may refuse or limit service to any person or entity at any time, in our sole discretion, including for suspected fraud, abuse, or violation of these Terms.

3. Fees, Billing, and Refunds

• Fees are set out at the time of purchase and are payable in full when you complete checkout. Payments are processed by our payment provider (currently Stripe); your payment card data is handled directly between you and that provider, and we do not store full card numbers.
• One completed purchase provisions one candidate assessment for one candidate. A purchase does not create any right to additional, extended, or re-run assessments.
• All fees are non-refundable except as expressly stated in these Terms or as required by applicable law. Once an assessment has been initiated, the associated fee is deemed earned and non-refundable. We may issue refunds at our sole discretion.
• You are responsible for any taxes arising from the purchase, excluding taxes based on our income.

4. Acceptable Use

You will not, and will not permit any candidate or other person to, use the Services to:

• Violate any applicable law or regulation, or the rights of any third party, including intellectual property and privacy rights;
• Reverse engineer, decompile, disassemble, scrape, or otherwise attempt to derive the source code, methodology, scoring logic, or internal workings of the Services;
• Probe, scan, or test the vulnerability of any part of the Services, or interfere with or disrupt their normal operation;
• Interfere with any candidate's assessment, facilitate or tolerate cheating in an assessment, or circumvent the intended AI access rules of an assessment environment;
• Resell, license, sublicense, or provide the Services to third parties, including as a service bureau;
• Generate or cause to be generated any "consumer report" or background check within the meaning of the Fair Credit Reporting Act or any similar law, or use the Services for any purpose other than Customer's own bona fide hiring process;
• Disclose, benchmark, or publicly or externally publish the Services, any Scorecard, or any aspect of the evaluation methodology or scoring process.

We have the right, in our sole discretion, to audit your use of the Services to verify compliance with these Terms.

5. Candidates

• Candidates are non-contracting participants. A candidate's participation is governed by (a) the candidate assessment instructions delivered inside the candidate's assessment environment and (b) our Privacy Policy. ScreenStack does not enter into any separate agreement with any candidate, except where required by law.
• No assessment creates any employment, agency, or other relationship between ScreenStack and any candidate. ScreenStack is a technology provider only and is not a party to, and takes no part in, any hiring or employment decision made by you or anyone else.
• You are solely responsible for: providing candidates with access and any disclosures required by applicable law; complying with all applicable employment, labor, anti-discrimination, data protection, privacy, and artificial intelligence laws and regulations (including any law that requires notice or bias audits for employment decision technology) in connection with your use of the Services and any Scorecard; and communicating with candidates about assessment results.

6. AI-Assisted Evaluations and Scorecards

• The Services use AI systems to generate Scorecards and related analysis. AI-generated output may be inaccurate, incomplete, biased, or erroneous, and may contain "hallucinations." We make no representation or warranty regarding the accuracy, completeness, reliability, timeliness, or impartiality of any AI-generated content.
• Scorecards are informational, advisory outputs intended to be reviewed and weighed by humans. You agree that you will not use any Scorecard or other evaluation output, alone or as the sole basis, to make an adverse employment decision, and that you must review all output using human judgment and in accordance with your own legal obligations before relying on it.
• We do not control, and are not responsible for, the availability, behavior, output, or pricing of the third-party AI model providers we engage on your behalf to run the Services.
• You are solely responsible for your use of any evaluation output and for compliance with all applicable law in connection with that use. Nothing in these Terms, the Services, or any Scorecard is legal or employment advice, and we do not provide legal or employment advice.
• If we determine, in our sole discretion, that an assessment was compromised (including by cheating, misuse of the assessment environment, or violation of the candidate assessment instructions), we may invalidate the assessment, withhold or revise any Scorecard, and take such further action as we deem appropriate, including terminating the Services and declining any refund, to the extent permitted by law.

7. Intellectual Property

• The Services, including the platform, assessment templates, evaluation methodology, scoring logic and weights, tooling, and documentation, are and remain the exclusive property of ScreenStack and its licensors, are protected by applicable intellectual property laws, and include trade secrets. Nothing in these Terms gives you any right, title, or interest in or to the Services. You may not disclose, benchmark, or otherwise reveal any aspect of the evaluation methodology or scoring process, or attempt to infer or reconstruct them.
• A candidate retains ownership of code the candidate independently creates. By submitting an assessment, a candidate grants ScreenStack a limited license to host, process, and evaluate that code solely for the purposes described in the candidate assessment instructions and our Privacy Policy.
• You may share a Scorecard within your organization for internal hiring purposes. You may not publish, distribute, or use a Scorecard, or any part of the Services, in any benchmark or any public or external disclosure without our prior written consent.
• If you provide us with feedback or suggestions regarding the Services, you grant us a non-exclusive, perpetual, royalty-free license to use that feedback without restriction or compensation.

8. Confidential Information

Each party may disclose to the other confidential information, including evaluation methodology, business information, and account or billing information. The receiving party will use confidential information solely to exercise its rights under these Terms, will protect it with at least the same degree of care it uses for its own confidential information (and in no event less than reasonable care), and will not disclose it except to personnel who need to know it and are bound by obligations at least as protective as this Section, or as required by law. These obligations do not apply to information that is or becomes publicly available without breach of these Terms, was lawfully known before disclosure, is independently developed without use of the other party's confidential information, or is lawfully received from a third party. The obligations in this Section survive termination or expiration of these Terms for so long as the information remains confidential under applicable law.

9. Data Protection

Our collection, use, and disclosure of personal data, including candidate personal data, is governed by our Privacy Policy, which is incorporated into these Terms by reference. You acknowledge and agree that: (a) in connection with your hiring, you are the primary actor in, and where applicable the data controller of, candidate data processing for your hiring purposes, and we process candidate data on your behalf to deliver and support the Services; (b) you are responsible for providing candidates with the notices and obtaining the consents required by applicable law for the processing of candidate personal data; and (c) to the extent of any conflict, the Privacy Policy controls for data protection matters.

10. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES, INCLUDING ANY SCORECARD AND ANY AI-GENERATED CONTENT, ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR ACCURACY, COMPLETENESS, OR TIMELINESS OF RESULTS. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS; THAT ANY SCORECARD WILL PRODUCE ANY PARTICULAR HIRING OUTCOME; OR THAT ANY ASSESSMENT ENVIRONMENT RESEMBLES ANY PRODUCTION CODING ENVIRONMENT. YOU ACKNOWLEDGE THAT YOUR RELIANCE ON ANY INFORMATION OR MATERIAL OBTAINED THROUGH THE SERVICES IS AT YOUR SOLE RISK.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL SCREENSTACK, ITS AFFILIATES, OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, OR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES, OR FOR ANY LOST PROFITS, REVENUES, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES, ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

IN NO EVENT WILL SCREENSTACK BE LIABLE FOR: (A) ANY HIRING, EMPLOYMENT, ADVERSE ACTION, OR RELATED DECISION OR ITS OUTCOMES; (B) ANY CLAIM BY OR ON BEHALF OF ANY CANDIDATE ARISING FROM YOUR USE OF THE SERVICES OR ANY EVALUATION OUTPUT; (C) ANY INACCURACY, ERROR, OMISSION, BIAS, OR HALLUCINATION IN ANY AI-GENERATED CONTENT OR SCORECARD; (D) ANY ACT OR OMISSION OF YOU, YOUR EMPLOYEES OR AGENTS, ANY CANDIDATE, OR ANY THIRD PARTY; (E) ANY FAILURE TO COMPLY WITH ANY APPLICABLE LAW; OR (F) ANY LOSS OF OR DAMAGE TO DATA. OUR AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICES WILL NOT EXCEED THE TOTAL FEES YOU PAID TO US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO LIABILITY. THE LIMITATIONS IN THIS SECTION DO NOT APPLY TO: (A) YOUR INDEMNIFICATION OBLIGATIONS UNDER SECTION 12; (B) YOUR PAYMENT OBLIGATIONS; OR (C) LIABILITY THAT CANNOT BE LIMITED BY APPLICABLE LAW.

12. Indemnification

You agree to indemnify, defend, and hold harmless ScreenStack and its affiliates, and each of their respective directors, officers, employees, agents, successors, and assigns, from and against any and all claims, demands, actions, liabilities, losses, damages, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use of the Services or any evaluation output, including any hiring or employment decision; (b) your breach of these Terms; (c) any content you provide or cause to be provided; (d) your failure to comply with any applicable law, including employment, anti-discrimination, and data protection laws; or (e) any allegation that the Services, or your use of them, infringe or misappropriate any intellectual property or other right of a third party. If a claim is made for which you must indemnify us, you will notify us in writing as soon as reasonably practicable. We may participate in the defense of the claim with counsel of our choosing. You will not settle or compromise any claim in a way that imposes any additional liability, cost, or obligation on us, or that admits fault on our behalf, without our prior written consent.

13. Suspension, Termination, and Service Changes

• We may suspend or terminate your access to all or any part of the Services at any time, with or without notice, if we determine in our sole discretion that you have breached these Terms or that your use presents a legal, security, or integrity risk, or where required by law. Upon termination, the licenses granted to you terminate, and Sections 2, 3, 7, 8, 9, 10, 11, 12, 14, and 15 survive termination.
• You may stop using the Services at any time.
• We may modify, sunset, or discontinue the Services or any feature at any time, including changes to assessment content, AI model providers, evaluation methodology, or scoring. We are not liable to you for any change or discontinuation.

14. Governing Law and Dispute Resolution

These Terms and the Services are governed by the laws of the jurisdiction in which the Company is organized, without regard to its conflict of laws principles. Except for claims seeking injunctive or other equitable relief, which may be brought in any court of competent jurisdiction, you and we each agree that any claim, action, or proceeding arising out of or relating to these Terms or the Services will be brought exclusively in the state or federal courts located in the jurisdiction where the Company's principal place of business is located, and you and we each irrevocably consent to the exclusive jurisdiction and venue of those courts.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, YOU AND WE AGREE THAT ANY CLAIM, ACTION, OR PROCEEDING WILL BE RESOLVED ONLY ON AN INDIVIDUAL BASIS AND NOT IN A CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION, AND EACH OF US HEREBY WAIVES ANY RIGHT TO A JURY TRIAL IN ANY SUCH ACTION.

15. General

• Entire Agreement. These Terms, together with the Privacy Policy, the candidate assessment instructions, and any documented order form, constitute the entire agreement between you and us regarding their subject matter and supersede all prior or contemporaneous agreements. In the event of conflict: these Terms control over the candidate assessment instructions for matters relating to Customer, and the Privacy Policy controls for data protection matters.
• Severability. If any provision of these Terms is held unenforceable, it will be modified to the minimum extent necessary to make it enforceable, and the remainder will continue in full force and effect.
• No Waiver. Our failure to enforce any provision of these Terms is not a waiver of that provision or any other provision. A waiver of one breach is not a waiver of any other breach.
• Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign or transfer these Terms at any time to a successor or an affiliate, including in connection with a merger, acquisition, or sale of assets. Any purported assignment in breach of this Section is void.
• No Third-Party Beneficiaries. These Terms do not confer any rights or benefits on any person other than the parties, including any candidate. Nothing in these Terms creates a contractual relationship between us and any candidate except to the extent expressly stated in the candidate assessment instructions or required by law.
• Independent Contractors. The parties are independent contractors. Nothing in these Terms creates any partnership, joint venture, agency, or employment relationship.
• Force Majeure. We are not liable for any failure or delay in performance (other than your payment obligations) to the extent caused by events beyond our reasonable control, including the unavailability of third-party networks, infrastructure, or services (including AI model providers), power failures, natural disasters, or legal requirements.
• Notices. Notices under these Terms may be given by email to support@screenstack.dev (for us) or to the email address on file for your account (for you).
• Counterparts. These Terms may be executed in counterparts, including electronically, each of which is deemed an original and all of which together are one agreement.
• Headings. Headings are for convenience only and do not affect the meaning of these Terms.
