SadhanAI is a private exam-preparation product. We are not affiliated with, endorsed by, sponsored by, or in any way connected to the Tamil Nadu Public Service Commission (TNPSC), the Government of Tamil Nadu, the Government of India, or any educational board. References to TNPSC and its exams (Group I, II, IV, TET, etc.) are made for the sole purpose of describing the exams our product helps you prepare for.
All content in SadhanAI — questions, explanations, study plans, mock tests, AI tutor responses — is provided strictly for educational and exam-preparation purposes. Nothing here constitutes:
Sadhana, our AI tutor, is built on large language models. While we fine-tune for TNPSC accuracy and require source citations for factual answers, AI-generated content can occasionally:
Always cross-verify high-stakes facts (specific dates, names, numbers, legal provisions) against the official Samacheer Kalvi textbooks, the Government of Tamil Nadu Gazette, or your own coaching material before relying on them in your exam answer.
Mock test scores, percentile predictions, weakness analysis, and "Sadhana predicts" rankings are generated from our internal database of past TNPSC papers and aspirant performance. These are statistical estimates, not official forecasts. Real exam outcomes depend on your final preparation, exam-day performance, the specific paper TNPSC sets that year, and dozens of factors outside our system. We do not guarantee any rank, score, or selection outcome.
Where we reproduce previous-year TNPSC questions for practice, we do so under the doctrine of fair use for educational purposes. Question text is paraphrased or transcribed from publicly available official papers. If you spot an error in our reproduction, write to hello@sadhanai.ai and we will correct it within 7 days.
Some references, quotes, charts, and dataset values cite third-party sources (NCERT textbooks, Samacheer Kalvi books, Government of Tamil Nadu gazettes, public news outlets). Copyright in those source materials belongs to their respective owners. SadhanAI claims no ownership of those underlying works.
SadhanAI runs on cloud infrastructure (AWS Mumbai region). We aim for 99.5% uptime but do not guarantee continuous availability. Scheduled maintenance windows are announced via in-app banner where possible. Refer to our Refunds Policy for what happens to subscriptions during extended outages.
We may modify product features, pricing tiers, or content without prior notice. Where changes materially reduce value (price increases, feature removal from a paid tier), existing subscribers receive 30 days notice via email + in-app banner.
To the fullest extent permitted by Indian law, SadhanAI and its operators are not liable for any indirect, incidental, special, consequential, or exemplary damages arising from use of the app — including but not limited to lost study time, missed exams, ranking outcomes, or claims of inaccurate content. Our total liability for any claim is capped at the subscription fees you paid us in the prior 12 months.
This disclaimer is governed by the laws of the Republic of India. Any disputes are subject to the exclusive jurisdiction of courts in Chennai, Tamil Nadu.
We take corrections seriously. Email hello@sadhanai.ai with the question, the answer we showed, and the correct answer with a source. Confirmed errors are fixed within 7 days and credited in our weekly changelog.
