1.Who we are & scope
This Privacy Policy explains how Chalkmark.school, a product operated by Teche Center ("Chalkmark.school", "we", "us"), handles information in connection with the Chalkmark.school website, applications, and services (the "Service"). It applies to all users of the Service and should be read together with our Terms & Conditions. By using the Service, you agree to this Policy.
2.Information we collect
| Category | Examples |
|---|---|
| Account & profile | Name, email address, phone number, WhatsApp number, password (stored only as a secure hash), school name, city, state, board, subjects taught, years of experience, referral code. |
| User Content | Classes, subjects, chapters, topics, syllabus entries, timetable, teaching pages and slides, prompts you type, and other content you create or upload. |
| AI interaction data | The prompts and content you submit to AI features and the resulting AI output, plus associated usage/token counts. |
| Transaction & wallet | Signup, subscription, wallet top-up and usage records, plan and billing status. Payment-card details are handled by our payment processors, not stored by us. |

You decide what to enter into the Service. Please do not submit sensitive personal information that is not necessary, and do not enter information about other people (including students) unless you are permitted to do so and have any required consents.
3.How we use information
- To provide, operate, maintain, and secure the Service and your Account;
- To authenticate you and send one-time passwords and service messages;
- To process signups, subscriptions, wallet balances, and payments;
- To generate AI output in response to your inputs;
- To monitor usage, prevent fraud and abuse, and enforce our Terms;
- To provide support and respond to your requests;
- To analyse and improve the Service, features, and reliability;
- To comply with legal obligations and protect our rights.
4.Legal bases
Where applicable law requires a legal basis, we rely on: performance of our contract with you (to provide the Service); your consent (e.g., for certain messaging); our legitimate interests (e.g., security, improvement, and fraud prevention); and compliance with legal obligations. Where we rely on consent, you may withdraw it at any time without affecting prior processing.
5.AI processing
Certain features send your prompts and related content to third-party AI providers (for example, Google Gemini) to generate output. This means the content you submit to AI features is transmitted to and processed by those providers, subject to their terms and privacy practices. Do not submit confidential or sensitive information to AI features that you would not want processed by a third party. We do not control how third-party AI providers use data submitted to them, and you use these features at your discretion.
6.Messaging & OTP
We use messaging providers (for example, WhatsApp / Meta) to deliver one-time passwords and account-related messages to the phone number you provide. Delivery depends on those providers and on your number being reachable. Your interactions with those providers are subject to their terms and privacy policies.
7.Payments
Payments are processed by third-party payment service providers (for example, Razorpay) and associated commerce systems. We receive transaction confirmations and limited details (such as amount, status, and a payment reference) but do not collect or store full payment-card numbers. Your payment information is handled in accordance with the processor's terms and privacy policy.
8.Cookies & similar technologies
We and our providers use cookies, local storage, and similar technologies to keep you signed in, remember preferences, secure the Service, and understand usage. Essential technologies are required for the Service to function. You can control non-essential cookies through your browser settings; disabling some may affect functionality.
9.How we share information
We do not sell your personal information. We share information only as needed:
- Service providers / processors: hosting, AI, messaging, payments, analytics, and similar vendors who process information on our behalf;
- Legal & safety: to comply with law, legal process, or lawful requests, and to protect the rights, safety, and property of Chalkmark.school, our users, or others;
- Business transfers: in connection with a merger, acquisition, financing, or sale of assets, your information may be transferred subject to this Policy;
- With your direction: where you ask us to share or make content available.
10.Data retention
We retain information for as long as your Account is active and as needed to provide the Service, then for any additional period required to comply with legal obligations, resolve disputes, prevent fraud, and enforce our agreements. We may retain de-identified or aggregated data indefinitely. You are responsible for keeping your own copies of important content; we are not a backup service and may delete data following account closure.
11.Security
We apply reasonable technical and organisational measures designed to protect information, such as encryption in transit, hashed passwords, access controls, and restricted internal access.
However, no method of transmission or storage is completely secure. We cannot and do not guarantee the absolute security of any information, and we are not liable for unauthorised access, loss, alteration, or disclosure of information beyond our reasonable control. You use the Service and provide information at your own risk.
12.International transfers
Our providers may process information in countries other than yours, which may have different data-protection laws. Where we transfer information, we take steps intended to ensure appropriate protection consistent with applicable law. By using the Service, you acknowledge that information may be processed outside your country.
13.Your rights & choices
Subject to applicable law, you may have the right to access, correct, update, or delete your personal information, to object to or restrict certain processing, to withdraw consent, and to request a copy of certain data. You can update much of your information within the Service, or contact us at contact@techecenter.com. We will respond as required by applicable law. We may need to verify your identity before acting on a request, and some data may be retained where permitted or required.
14.Students & minors
The Service is intended for teachers and is not directed to children. We do not knowingly collect personal information directly from children. If you choose to enter information about students or other individuals, you are solely responsible for having a lawful basis and any required consents, and for complying with applicable laws and your institution's policies. If you believe a minor has provided us personal information directly, contact us and we will take appropriate steps.
15.Third-party links
The Service may contain links to third-party sites and services that we do not control. This Policy does not apply to them. Please review the privacy policies of any third-party services you use.
16.Changes to this policy
We may update this Policy from time to time. The "Last updated" date shows the latest version, and material changes may be communicated through the Service or by other reasonable means. Your continued use of the Service after changes take effect constitutes acceptance of the updated Policy.
