Privacy Policy – Charaka Samhita

Last updated: 14 November 2026

Charaka Samhita ("the App") respects the privacy of all users and is committed to protecting personal information. This Privacy Policy explains what information we collect, how we use it, and how we keep it safe.

1. Owner & Contact Information

This app is operated by:

Owner: Abhay Arya (Vaidik Apps)

Email: support@vaidikapps.com

If you have any questions about this Privacy Policy, you may contact us at the email above.

2. Information We Collect

The App collects only the minimum information necessary to provide its services.

A. User-Provided Information

When you sign in using Google Sign-In (Android) or Sign in with Apple (iOS), we may receive:

• Email address (for account identification) — if you choose Apple's "Hide My Email" option, we receive a private relay email instead of your real one
• Display name (to personalize experience)
• Profile photo URL (for user profile display, when provided)

We do not collect phone numbers or any unnecessary personal data.

B. Automatically Collected Information

Through Firebase services, we may collect:

• Device information
• App usage data (analytics)
• Crash reports
• Performance diagnostics

No sensitive personal data such as location, contacts, photos, or files is collected.

3. How We Use Your Information

We use your information only to:

• Create and manage your account
• Provide access to Charaka Samhita text (Moolapatha and Ayurveda Dipika commentary)
• Personalize reading experience (highlights, font size, themes)
• Improve app performance and fix bugs
• Ensure app security and prevent misuse

We do NOT use your data for advertising or marketing.

4. Subscription & Payments

The App offers subscription-based premium features (yearly and lifetime plans).

• On Android, payments are processed through Google Play
• On iOS, payments are processed through Apple's App Store
• Yearly subscription renews automatically unless cancelled
• You can manage or cancel subscriptions via your Google Play Store account (Android) or your iPhone's Settings → [Your Name] → Subscriptions (iOS)

5. Data Sharing

We do NOT sell, trade, or share your personal data.

Data is processed only through trusted services:

• Firebase Authentication
• Firebase Firestore
• Firebase Crashlytics
• Firebase Cloud Messaging (only for reply notifications of the Help & Contact chat)

These services follow Google's privacy standards.

6. Help & Contact chat (सहायता-चैट)

The app has a Help & Contact chat (More → Help & Contact → Chat). Using it is optional. If you write to us there, the following is kept on our own server (vaidikapps.com, hosted on a Hostinger VPS in India) so that we can read and answer you:

• the name and message you send, and any picture you attach;
• if you are signed in, the email address and name of your Google or Apple account, attached to your message;
• a push token of your phone (Firebase Cloud Messaging, a Google service), used only to notify you when we reply.

Pictures are deleted automatically after 90 days and messages after 2 years. We do not sell or share this information with any third party; it is used only to answer you. To have your chat data removed earlier, write to support@vaidikapps.com.

7. Data Security

We take appropriate measures to protect your data:

• Secure Firebase servers (account data); Help & Contact chat data is kept on our own server, see the Help & Contact chat section
• Data encryption in transit and at rest
• Restricted access to user data

However, no system is 100% secure, but we follow best practices.

8. Data Retention & Account Deletion

We retain your personal information only for as long as your account remains active, in order to provide app services such as your subscription status, reading preferences, and saved highlights.

• Account data (email, display name, profile photo, subscription records, highlights) is retained for as long as your account exists.
• Any automatically collected device/diagnostic data is retained only for a limited period as governed by Firebase's default retention settings, and is not linked to your identity beyond what is needed to maintain and improve the app.
• You can request account deletion at any time. Upon a deletion request, we permanently delete your account data, including highlights and subscription records, within 30 days.

To request deletion, contact:

support@vaidikapps.com

Anonymous usage count

To know how many people use the App, it sends a small anonymous signal to our own server (vaidikapps.com) when it is opened and every two minutes while it is open. The signal contains only: the app name, a random number created inside the App (not linked to your name, email, phone number, account or device identifiers), the platform (Android / iPhone / web), the app version and the phone language.

Our server uses the connection's IP address only at that moment to find the country only (no state or city). The IP address itself is not stored. We see only totals (for example “India — 230 users”), never who a person is. This data is not sold or shared with anyone and is not used for advertising.

9. Children's Privacy

This app is not intended for children under 13.

We do not knowingly collect data from children.

10. Third-Party Services

The app uses:

• Google Firebase
• Google Play Services
• Google Play Billing (Android)
• Apple App Store / StoreKit (iOS)
• Firebase Cloud Messaging (reply notifications of the Help & Contact chat)
• Sign in with Apple (iOS)

Any changes will be reflected within the app or via an updated link.
