Privacy Policy
Last updated: 25 September 2026
This policy explains what information Chaturmind (“we”, “us”) collects when you use chaturmind.com and the Chaturmind Android app, how we use it, and the choices you have. The app shows the same website, so this policy covers both.
Information we collect
- No account needed. All content is free to read without signing up. We don’t ask for your name, email address or password.
- Learning progress. Your browser stores a random anonymous identifier. We use it to remember which lessons you’ve completed. It isn’t linked to your name or email.
- AI tutor questions. If you use the “Ask AI” tutor, your question and the lesson it relates to are sent to our server and to our AI provider (OpenAI) to generate an answer. Please don’t include personal information in your questions.
- Usage and technical data. Like most websites, our hosting providers (Vercel and Render) process technical data such as IP address, browser type, pages requested and timestamps, to deliver the site, measure performance and keep it secure.
- Visit statistics. We record anonymous page views to understand how people find and use Chaturmind: the page, the anonymous identifier, how you arrived (for example a search engine, Instagram or a campaign link), your approximate country and city (derived from your IP address, which we don’t store), and your device type, browser and operating system. We use these figures only in aggregate, and delete individual page views after about 13 months.
- Emails you send us. If you contact us, we keep your message and email address in order to reply.
Cookies and advertising
We use Google AdSense to show ads, which keeps Chaturmind free. Ads and cookies work as follows:
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You can opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalised advertising at www.aboutads.info.
- Learn more about how Google uses information from sites that use its services.
- Visitors in the European Economic Area, the UK and Switzerland are asked for consent before personalised ads or non-essential cookies are used. You can change your choice at any time from the privacy options link shown on the site.
We also use essential browser storage (for example, the anonymous progress identifier and your light/dark theme choice). You can clear it at any time through your browser settings.
How we use information
- To provide the site and app, remember your progress and answer AI tutor questions.
- To understand which content is useful and improve it.
- To show ads that keep the content free.
- To keep the service secure and prevent abuse.
We do not sell your personal information.
Sharing
We share information only with service providers who help us run Chaturmind: hosting (Vercel, Render), database hosting (MongoDB Atlas), advertising (Google AdSense) and AI answers (OpenAI). We may also share it when the law requires us to.
Data retention
Progress records tied to the anonymous identifier are kept while the service is active. You can remove the link to them at any time by clearing your browser storage. Server logs are kept only as long as our hosting providers need them for operations and security.
Children
Chaturmind is intended for learners aged 13 and over. We do not knowingly collect personal information from children under 13.
Your rights
Depending on where you live (for example, under the GDPR in the EU/UK or India’s Digital Personal Data Protection Act), you may have the right to access, correct or delete personal data we hold about you, or to object to how we use it. To make a request, email us at the address below.
Changes to this policy
We may update this policy from time to time. The “Last updated” date at the top shows when it last changed.
