CalcAI — Terms of Service, Acceptable Use & Policies (Draft v4) Effective date: [Month DD, 2025] Plain‑English summary (not a substitute for the full terms): CalcAI modifies TI‑84‑series calculators to add an AI assistant. We’re not affiliated with Texas Instruments or OpenAI. Use our products legally and ethically. Do not use them for exams or to cheat. You’re responsible for network access, any AI/API costs, and following school/testing rules. Payments are processed by Stripe (we don’t store full card numbers). Limited workmanship warranty is 14 days from delivery; opening, modifying, or flashing firmware without our written OK voids the warranty.Contact us on our Discord server (link on calcai.cc) before you attempt any repair or modification. 1) Agreement to these terms By buying, using, or sending us a calculator to modify, you agree to these Terms of Service (the “Terms”), our Acceptable Use Policy (AUP), and any policies linked here. If you do not agree, do not purchase or use CalcAI products or services. These Terms are between you and CALCAI, located at [street, city, state, ZIP, country] ( “CalcAI,” “we,” “us,” or “our” ). 2) What we sell; what we don’t Hardware mods. We sell calculators we have modified, and/or we modify devices you send to us. Modifications may include microcontrollers (e.g., ESP32), camera modules, firmware, and case work. Software & AI connectivity. Our products can connect to cloud AI services (e.g., “ChatGPT‑style” assistants). Some features need Wi‑Fi and an AI provider account or API key. Not a TI or OpenAI product. CalcAI is not affiliated with Texas Instruments, OpenAI, College Board, ETS, ACT, or any test authority. Trademarks belong to their owners. Educational tool, not an exam device. Our products are designed for learning and productivity. They are not authorized for use on proctored exams unless the test rules explicitly say so. 3) Academic integrity & exam rules (strict) No cheating. Do not use CalcAI devices to cheat, gain unfair advantage, or violate school, university, or testing rules. Exam bans. Unless the testing body explicitly allows a specific CalcAI model and configuration in writing, assume it is not allowed. • • • • • • 1
