3. 内容来源与准确性 / Content and Accuracy
本站题目、答案、解析及参考出处整理自第三方练习资料，并非官方真题，亦不代表任何官方考试的题型、范围、比重或及格标准。学习模块中的知识卡为运营者依据公开教材与规范自行整理、改写的考点摘要，不包含任何教材原文、图表或扫描件，所标页码仅为方便使用者对照自购的正版教材。本站不对任何内容的准确性、完整性、时效性或与现行法规（包括 CSA C22.1 加拿大电气规范及各省修订本）的一致性作出任何保证。使用者应以现行官方规范、法规及权威教材为准，并自行核实。
Questions, answers, explanations and references are compiled from third-party practice material. They are not official examination questions and do not represent the format, scope, weighting or pass mark of any official examination. The study cards in the Study module are the operator's own paraphrased summaries of key points drawn from publicly available textbooks and codes; they contain no verbatim text, figures or scans, and page references are provided solely to help users consult their own legitimately purchased copy. No warranty is given as to the accuracy, completeness, currency or consistency of any content with applicable codes and regulations, including CSA C22.1 and provincial amendments. Users must rely on, and verify against, current official codes, regulations and authoritative texts.

本站仅供个人、非商业学习使用。未经许可，不得复制、转载、抓取、分发、出售本站题库或将其用于任何商业用途。本站尊重知识产权；如权利人认为本站任何内容侵犯其合法权益，请与运营者联系，核实后将及时移除相关内容。
The Site is for personal, non-commercial study only. The question bank may not be copied, republished, scraped, distributed, sold or used for any commercial purpose without permission. The Site respects intellectual-property rights: a rights holder who believes any content infringes their rights may contact the operator, and the content will be removed promptly upon verification.
7. 数据与隐私 / Data and Privacy
本站不要求注册，不收集姓名、邮箱等个人身份信息，不用于广告。进度默认只保存在这台设备的浏览器里，清除浏览器数据或换设备都会看不到。
如果你设置了同步码：做题记录、学习进度、备考计划和单词进度会存在本站自己的服务器上（Cloudflare），以同步码作为钥匙（只保存同步码的加密摘要，不保存同步码本身）。知道同步码的人都能看到和改动这份进度，请像密码一样保管，别发给别人。点「断开」只是停止同步，云端那份不会自动删除；如需删除，请通过站内反馈联系运营者。
如果你提交纠错或反馈：你写的说明、相关题号或小节号、浏览器类型和大致所在国家/地区会保存 180 天，并以邮件通知运营者，只用于修正内容。
No registration is required; no names or email addresses are collected and nothing is used for advertising. By default your progress stays in this browser only. If you set a sync code, your answers, study progress, plan and vocabulary progress are stored on the Site's own server (Cloudflare) under a hash of that code: anyone who knows the code can read and change that progress, so keep it like a password. Disconnecting stops syncing but does not delete the cloud copy; ask the operator through the feedback form to delete it. Feedback you submit (your note, the question or section number, browser type and approximate country) is kept for 180 days and emailed to the operator, only to correct content.
8. 适用法律 / Governing Law
本声明受加拿大安大略省法律及适用的加拿大联邦法律管辖。继续使用本站即视为你已阅读、理解并同意上述全部条款；如不同意，请停止使用。
This notice is governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein. By continuing to use the Site you acknowledge that you have read, understood and agreed to these terms; if you do not agree, please discontinue use.
