Privacy Policy

Last updated: 28 June 2026

This Privacy Policy explains what information Lectrix collects, how we use it, who we share it with, and the choices you have. By using Lectrix, you agree to the practices described here.

1. Who we are

Lectrix (“Lectrix”, “we”, “us”, “our”) is a study-tracking application for exam preparation, operated as an independent project by an individual founder based in India. For any privacy questions or requests, contact us at support@lectrix.app.

2. Information we collect

We collect only what we need to run the service:

• Account information (via Google Sign-In). When you sign in with Google, we receive your name, email address, and Google profile picture. We use this to create and secure your account.
• Study data you create. The subjects, faculty, lectures, parts, topics, target dates, schedules, streaks, and completion progress you add or generate while using Lectrix.
• Payment-related information. When you pay for Lectrix, we receive confirmation of your payment and record that your account has paid (such as the amount, date, method, and an optional note). Payments made manually via UPI are confirmed through a messaging channel such as WhatsApp (for example, a UPI transaction reference or screenshot). Where payments are processed through a third-party payment gateway, that provider handles your payment details directly. In all cases, we do not collect or store your card details, bank account numbers, or UPI PIN.
• Notification data. If you choose to enable push notifications, your browser provides a device subscription token that lets us send study reminders. You can disable this at any time.
• Technical and usage data. Like most websites, our hosting and backend providers automatically log basic technical information such as IP address, browser and device type, and timestamps, for security, reliability, and abuse prevention.

3. How we use your information

• To provide the service — saving and displaying your subjects, schedule, and progress.
• To authenticate you and keep your account secure.
• To grant and manage access after a payment has been confirmed.
• To send study reminders and notifications you have opted into.
• To respond to your messages and provide support.
• To maintain, debug, and improve the product.
• To protect against fraud, abuse, and security incidents.

4. Google user data

Lectrix’s use of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements. We only request basic profile information (your name, email, and profile picture) for the sole purpose of creating and authenticating your account. We do not sell this data, and we do not use it for advertising.

5. How we share information

We do not sell your personal data. We share information only with the service providers that help us operate Lectrix, and only as needed:

• Supabase — database, authentication, and backend infrastructure.
• Vercel — application hosting and delivery.
• Google — sign-in / authentication.
• Cloudflare — domain, DNS, and security.
• Resend — transactional email (e.g. account-related messages), where used.
• Messaging platforms (e.g. WhatsApp / Meta) — to coordinate access and payments and to provide support.
• Payment processors / gateways — to process payments and subscriptions, where an automated payment gateway is used.

We may also disclose information if required by law, or to protect the rights, safety, and security of our users or the service.

6. Data retention

We keep your information for as long as your account is active. If you ask us to delete your account, we will delete your personal data within a reasonable period, except where we are required to retain certain records (for example, basic payment records) to comply with legal obligations.

7. Your rights and choices

Subject to applicable law, including India’s Digital Personal Data Protection Act, 2023, you may request to access, correct, or delete your personal data, or withdraw consent you have given. To make a request, email support@lectrix.app. You can also revoke Lectrix’s access to your Google account at any time from your Google Account permissions page.

8. Data security

We take reasonable measures to protect your data, including encryption in transit and database access controls. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

9. Children

Lectrix is intended for users aged 18 and over. We do not knowingly collect personal data from children. If you believe a minor has provided us with personal data, please contact us and we will take appropriate steps to remove it.

10. International processing

Your information may be stored and processed in India and in other countries where our service providers operate. By using Lectrix, you consent to such processing.

11. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above. Continued use of Lectrix after changes take effect means you accept the updated policy.
