These Terms of Use (“Terms”) govern your access to and use of the CHST & OHST Prep mobile application and related services (the “App”). By downloading, accessing, or using the App, you agree to these Terms. If you do not agree, do not use the App.
If you use the App for an organization, you confirm that you have authority to accept these Terms for that organization.
The App is an independent study and practice tool. It is provided for general educational and exam-preparation purposes only. It is not a certification, licensing, legal, regulatory, medical, engineering, workplace-safety, or professional-advice service.
The App does not guarantee that you will pass an examination, obtain a credential, satisfy an employer or regulator, or achieve any particular result. You are responsible for confirming current requirements, official blueprints, laws, regulations, standards, deadlines, and examination procedures with the applicable official source.
The App does not contain or provide actual certification examination questions and is not a substitute for official study materials, instruction, workplace procedures, competent professional advice, or emergency services.
CHST & OHST Prep is independent and is not affiliated with, sponsored by, endorsed by, or administered by BCSP, OSHA, NIOSH, ISO, or any other examination body, government agency, standards organization, publisher, or trademark owner.
Names, acronyms, trademarks, service marks, standards, regulations, blueprints, references, and other third-party materials remain the property or responsibility of their respective owners. Their appearance in the App is for identification, educational reference, or comparative purposes and does not imply endorsement, authorization, partnership, or ownership by the Operator.
Nothing in these Terms is an admission that the Operator owns any third-party question, examination item, answer choice, explanation, standard, blueprint, source text, trademark, or other protected material. The Operator does not represent that every underlying fact, idea, topic, formula, or reference used in practice content is proprietary to the Operator. Rights in third-party materials are reserved to their respective owners.
The Operator claims rights only in the App’s code, interface, compilation, branding, and other material to the extent the Operator owns or is authorized to use those elements. The Operator may revise, replace, restrict, or remove any practice item or other material at any time.
If you believe that a practice item or other material infringes your rights, send the relevant item identifier, a description of the claimed right, and a way to contact you to [email protected]. The Operator may investigate, restrict, revise, or remove the material while reviewing the report. Any response, review, restriction, revision, or removal is not an admission of ownership, infringement, liability, or wrongdoing.
Subject to these Terms, the Operator grants you a limited, personal, non-exclusive, non-transferable, revocable license to use the App on Apple devices that you own or control for personal, non-commercial study purposes.
You may not, except where applicable law or the relevant third-party license permits it:
