Privacy / Charaka NEET-MDS

Charaka NEET-MDS
privacy policy.

One policy covers Saras JEE, Charaka NEET-UG, Charaka NEET-PG and Charaka NEET-MDS.

Last updated 7 June 2026

Saras Educator, Charaka, Charaka NEET PG & Charaka NEET MDS

Effective date: 18 May 2026 · Last updated: 7 June 2026 (Charaka NEET-UG Remove Ads subscription added)

The whole policy in one sentence. Saras Educator (JEE), Charaka (NEET-UG), Charaka NEET PG (NEET PG) and Charaka NEET MDS (NEET MDS) are sister study apps from the same India-based team: none runs a server, none holds an account for you, none sees what you study; the only thing that leaves your device is an anonymous ad request to Google AdMob (configured to be as private as Google permits), and, for the apps that offer Remove Ads, an anonymous purchase receipt from Apple when you buy it.

This Privacy Policy explains how Saras Educator, Charaka, Charaka NEET PG and Charaka NEET MDS (“we”, “us”, “our”, “the Apps”) handle personal information. It is written to comply with India’s Digital Personal Data Protection Act, 2023 (DPDP Act), Apple’s App Store privacy requirements, and EU/UK GDPR principles where applicable.

The substantive practices for all four Apps are identical except for in-app purchases: Saras Educator offers a one-time Remove Ads purchase, and Charaka (NEET-UG), Charaka NEET PG and Charaka NEET MDS each offer an auto-renewable monthly Remove Ads subscription. Sections marked (Saras only), (Charaka NEET PG only), (Charaka NEET MDS only), or similar are flagged explicitly. Everything else applies to all four Apps.

Where this Policy refers to “the App”, it means whichever app you are currently using. Where it refers to “the Apps” (plural), it means all four collectively.

We don’t run a server. Your practice attempts, notes, sketches, imported documents, mock-test results, and AI tutor conversations live only on your iPhone or iPad, for every App, in separate sandboxes. We cannot see them. We do not collect them. We have no way to access them, ever.

1. Who we are

Saras Educator, Charaka, Charaka NEET PG and Charaka NEET MDS are independent educational mobile apps developed in India by the same team:

  • Saras Educator: JEE Main / JEE Advanced preparation. Brand: the Sarus crane, indigo-purple palette.
  • Charaka: NEET-UG (undergraduate medical entrance) preparation. Brand: the mortar-and-pestle / neem-leaf, sage-cream-saffron palette.
  • Charaka NEET PG: NEET PG (postgraduate medical entrance) preparation, for MBBS graduates. Brand: the mortar-and-pestle / neem-leaf, medical-blue palette.
  • Charaka NEET MDS: NEET MDS (postgraduate dental entrance) preparation, for BDS graduates. Brand: the mortar-and-pestle / neem-leaf, violet palette.

For the purposes of the Digital Personal Data Protection Act, 2023 (“DPDP Act”), we act as the Data Fiduciary with respect to any personal data processed in connection with any App.

Contact emails (use the one that matches the App you have a question about):

These addresses also handle grievance redressal under Section 8(9) of the DPDP Act (see Section 14).

2. What this policy covers

This policy applies to your use of the Saras Educator, Charaka, Charaka NEET PG and Charaka NEET MDS mobile applications on iOS and iPadOS, distributed via the Apple App Store. It does not apply to:

  • Third-party websites or services you may navigate to from any App.
  • Apple’s own services (Apple Intelligence, the App Store, StoreKit, iCloud backups of your device if you have those enabled, etc.), covered by Apple’s own privacy policy.
  • Google AdMob’s wider data handling, covered by Google’s privacy policy, with the caveat that we have configured AdMob with the most restrictive options available (see Section 3.3).

It explains: what information the Apps process, who processes it, where it goes, how long it is kept, and your rights as a Data Principal under the DPDP Act, GDPR (where applicable), and other laws.

3. Information we collect

3.1 Information collected by us directly

Zero. We collect nothing. This is true for all four Apps.

  • No account creation. No sign-in. No email. No phone number.
  • No iOS permission prompts of any kind beyond those you optionally trigger (e.g., the Photos picker if you import an image, the file picker if you import a PDF). The Apps never ask for camera, location, microphone, contacts, or App Tracking Transparency access.
  • No analytics SDK. No crash reporter operated by us. No A/B testing framework. No remote logging.
  • No backend, no server, no database we operate.

All practice data (your attempts, mastery scores, time spent per question, streaks, hints used, notes, sketches, imported PDFs, mock-test results) is stored only on your device using Apple’s SwiftData framework (an encrypted SQLite database, sandboxed per app). It is never transmitted anywhere because there is nowhere to transmit it to.

The Apps’ on-device stores are independent. Your progress in each app lives in its own sandbox and never sees the others, even when more than one is installed.

3.2 Information processed by Apple on our behalf

  • Apple Intelligence (Foundation Models) processes your AI tutor / AI-assist prompts and responses entirely on your device, in every App that offers AI help. Apple’s standard on-device AI privacy guarantees apply. We do not see, log, or transmit these prompts.
  • The App Store handles app installation and updates for all Apps. Apple does not share your Apple ID or personal information with us beyond aggregated, anonymous developer metrics (install counts by country, OS version distribution, etc.).
  • StoreKit purchase entitlements (all four Apps): when you buy Remove Ads (a one-time purchase in Saras Educator; an auto-renewable monthly subscription in Charaka (NEET-UG), Charaka NEET PG and Charaka NEET MDS), Apple sends the App an anonymous receipt/entitlement indicating the purchase is active. We do not see your name, email, billing address, or payment details, only a yes/no “is Remove Ads active” signal used to switch ads off.

3.3 Information processed by Google AdMob

All four Apps display advertisements served by Google AdMob (Google Mobile Ads SDK) to keep them free. In all four Apps, ads are shown to users who have not bought or subscribed to Remove Ads and are suppressed for those who have.

To deliver an ad, AdMob may access limited device information including:

  • A device identifier for advertising attribution (not the IDFA; see configuration below);
  • General device characteristics (model, iOS version, screen size, language, country);
  • Coarse network information (connection type, IP address from which the request originates).

We configure the SDK with the most restrictive privacy posture appropriate to each App’s audience:

  • Saras Educator and Charaka (NEET-UG), whose audiences include minors, use tagForUnderAgeOfConsent = true, treating every user as below the age of digital consent worldwide.
  • Charaka NEET PG (an adults-only app for MBBS graduates) and Charaka NEET MDS (an adults-only app for BDS graduates) apply Google’s age-restricted treatment instead.
  • In all Apps: publisherPrivacyPersonalizationState = .disabled (no personalised advertising), npa=1 on every request, maxAdContentRating = .general (G-rated creatives only), and SKAdNetwork attribution only. No IDFA is used and no App Tracking Transparency prompt is ever shown.

The result: ads you see are contextual (based on the App’s category: exam prep) and not personalised based on your behaviour. No tracking profile is built about you.

Ads are deliberately suppressed inside mock tests, AI surfaces, and the Notes / Sketches / PDF reader in every App.

3.4 What we do NOT collect

For absolute clarity, none of the Apps collect or process:

  • Your name, email address, phone number, postal address, or any contact information.
  • Your physical location, IP-based location, or movement history.
  • Your contacts, calendar, photos, microphone audio, or camera input.
  • Your AI prompts or responses (these stay on-device via Apple Intelligence).
  • Your practice attempts, mock-test answers, mastery scores, notes, sketches, or imported documents.
  • Your Apple ID, iCloud account, or any other identifier that could link you to a person.
  • Any behavioural advertising profile.
  • Any biometric, health, or patient data.

4. Why we process this data (purposes)

Because we do not collect data ourselves, the only third-party processing on our behalf is via Apple (App Store + Apple Intelligence + StoreKit) and Google AdMob (ad delivery):

Data flowApp(s)Purpose
On-device practice / progress storageAllCompute your dashboard, streaks, mastery scores, and mock-test results inside the App.
Apple App Store install + update telemetryAllStandard developer-platform telemetry (aggregated, anonymous).
Apple Intelligence on-device inferenceAll (where offered)Run the AI tutor / AI assist on your device. No data leaves the device.
Apple StoreKit purchase entitlementSaras Educator; Charaka (NEET-UG); Charaka NEET PG; Charaka NEET MDSUnlock the ad-free experience for Remove Ads buyers/subscribers.
Google AdMob ad requestAll (non-purchasers)Serve a contextual ad to keep the App free.
SKAdNetwork install attributionAllPrivacy-preserving aggregated install attribution.

Under the DPDP Act, we rely on:

  • Consent (Section 6): by using an App, you consent to AdMob’s processing for ad delivery as described above. (Saras Educator / Charaka (NEET-UG) / Charaka NEET PG / Charaka NEET MDS) You separately consent when you choose to buy Remove Ads. You may withdraw consent at any time by uninstalling the App (and, for the Charaka (NEET-UG), Charaka NEET PG and Charaka NEET MDS subscriptions, by cancelling them in your App Store settings).
  • Legitimate uses (Section 7): basic functioning of the Apps (storing your practice data on your own device, and the anonymised aggregate metrics Apple and Google provide to all developers).

If a parent or guardian has provided consent on behalf of a child (Saras Educator / Charaka NEET-UG), we rely on that consent.

Under GDPR (EEA / UK), the basis is legitimate interests for ad-supported free distribution and consent where required by local law. Since personalisation is disabled in every App (Section 3.3), no personalised-ad consent is collected or processed.

6. How long we keep your data

We don’t keep your data. We never had it. There is nothing for us to retain or delete on our side.

  • On-device data: kept until you delete it in the App or uninstall the App. Uninstalling removes everything; reinstalling starts you back at zero.
  • Apple purchase entitlements / subscriptions (Saras Educator; Charaka (NEET-UG); Charaka NEET PG; Charaka NEET MDS): retained by Apple under Apple’s policies, not ours.
  • AdMob and Apple telemetry logs: retained per the respective third party’s published retention policy.

We do not back up your data to any cloud service operated by us.

7. Sharing your data

We share nothing because we collect nothing. We do not sell, rent, trade, or transfer any user data (not to advertisers, not to data brokers, not to any third party) because no user data is in our possession to share.

The only data flows that leave your device are:

  • Ad requests to Google AdMob (all Apps, for non-purchasers): limited device information as described in Section 3.3. We do not see these requests. Google does, subject to Google’s privacy policy and the restrictive settings we have applied.
  • App Store install / update / anonymous crash reports to Apple (all Apps): standard Apple developer telemetry. Apple may share aggregated, non-identifying statistics with us.
  • StoreKit purchase receipts (Saras Educator, Charaka (NEET-UG), Charaka NEET PG and Charaka NEET MDS, if you buy Remove Ads): Apple sends the App an anonymous “purchased / active” signal.

We will only ever disclose information to a third party (including a government authority) if compelled by valid Indian legal process, and only to the extent legally required. In practice we would have nothing to disclose.

8. Where your data is stored

  • Your practice data: on your device, in whichever country your device is physically located.
  • App Store / Apple Intelligence / StoreKit data: processed by Apple at facilities Apple operates globally.
  • AdMob data: processed by Google at facilities Google operates globally. AdMob impression logs may transit and be stored on servers outside India, subject to Google’s standard cross-border data-transfer safeguards.

If you have iCloud backups enabled at the iOS level, Apple’s backup mechanism may snapshot each App’s data into your iCloud account; that is covered by Apple’s privacy policy, not ours.

Under DPDP Act Section 16, the Government of India may restrict transfers of personal data to certain countries. We comply with any such notifications applicable at the time.

9. Children’s privacy

Saras Educator and Charaka (NEET-UG) are intended for entrance-examination aspirants typically aged 16 to 19, with a minimum age of 13. Under the DPDP Act, any user under 18 is a “Child” and special protections apply: a parent or guardian must provide verifiable consent before a Child uses the App, and we run no behavioural advertising profiling on Children (or anyone) because of the tagForUnderAgeOfConsent = true setting applied to those two apps. Because Charaka (NEET-UG) now offers a monthly Remove Ads subscription and its audience includes users under 18, any purchase by a minor is subject to the device holder’s consent and Apple’s parental controls / Ask to Buy, and the subscription unlocks ad removal only: no questions, features, or content are ever gated behind it.

Charaka NEET PG (for MBBS graduates and interns) and Charaka NEET MDS (for BDS graduates) are intended for adults aged 18 and over and are not directed at children; we do not knowingly process the personal data of anyone under 18 through them.

Across all Apps we do not track children’s data for marketing purposes. If you are a parent and discover your Child has used Saras Educator or Charaka (NEET-UG) without your consent, or has been shown inappropriate content, please contact us at the relevant email in Section 1; we will work with you to address it.

10. Your rights under the DPDP Act

As a Data Principal, you have the right to:

  1. Right to access: request a summary of personal data we process about you. (Answer for all Apps: none.)
  2. Right to correction: request correction of inaccurate or misleading personal data. (Not applicable since we hold none.)
  3. Right to erasure: request deletion of your personal data. For every App, uninstalling removes everything from your device; that is the only place your data exists.
  4. Right to grievance redressal: file a complaint with our Grievance Officer (Section 14). If unsatisfied, escalate to the Data Protection Board of India.
  5. Right to nominate: appoint another individual to exercise these rights on your behalf in the event of your death or incapacity.
  6. Right to withdraw consent: withdraw any previously given consent at any time by uninstalling the relevant App.

For most users these rights are effectively moot because we hold no personal data. They are listed for completeness and DPDP Act compliance. To exercise any of them, write to the email for the relevant App (Section 1).

11. Cookies and tracking technologies

The Apps are native iOS applications and do not use HTTP cookies, web tracking pixels, or analytics beacons of their own. The AdMob SDK uses Apple’s SKAdNetwork framework for install attribution; this is privacy-preserving by design and does not involve cross-app tracking identifiers.

12. Security

We protect your data using:

  • Local-only storage: your practice data does not leave your device in any App.
  • iOS Data Protection: SwiftData files are encrypted at rest by iOS when the device is locked.
  • HTTPS / TLS: any optional network calls (App Store, AdMob, Apple Intelligence platform infrastructure) use TLS.
  • No server-side database: there is no server we operate that stores your personal data, so a server breach by us is structurally impossible.
  • App Store distribution only: the Apps are distributed exclusively via Apple’s signed-and-reviewed pipeline.

No security measure is 100% effective. Since the Apps store data only on your device, security on your device is primarily managed by iOS itself (Face ID, Touch ID, passcode, Find My, etc.).

13. Data breach notification

In the unlikely event of a personal data breach affecting any user data we control, we will notify affected users and the Data Protection Board of India within the timelines required by the DPDP Act and any subsequent rules. Since no App maintains a server with user data, the universe of breachable data on our side is essentially nil.

14. Grievance redressal

Under Section 8(9) of the DPDP Act, we have designated the following Grievance Officers (same team):

Response times (all Apps): acknowledgement within 48 hours; substantive response within 7 working days; resolution within 30 days for complex matters, as permitted under the DPDP Act. Please mention “Privacy” or “DPDP grievance” in your subject line for fastest routing.

If you are not satisfied with our response, you may escalate to the Data Protection Board of India as constituted under Section 18 of the Digital Personal Data Protection Act, 2023. Until the Board’s portal is published, complaints may also be sent to the Ministry of Electronics and Information Technology (MeitY).

15. International users

The Apps are available globally via the App Store. Users outside India are nonetheless protected by the privacy guarantees in this policy, most notably the “we don’t collect anything” principle that applies identically worldwide.

European users have rights under the GDPR and UK GDPR (access, rectification, erasure, restriction, portability, objection, and not to be subject to automated decision-making). California users have rights under the CCPA / CPRA. Because we do not collect personal data, most of those rights are moot in practice, but we will honour any reasonable request at the contact email for the relevant App (Section 1).

16. Changes to this policy

We may update this Privacy Policy from time to time to reflect changes in any App, the law, or our data practices. When we make material changes, we will update the “Last updated” date at the top, highlight the change inside the App’s release notes for that version, and request fresh consent where required by law.

We will never expand any App’s data collection without prominent notice in the App.

Your continued use of the relevant App after such updates constitutes acceptance of the revised policy.

17. Contact

For any privacy questions, grievances, or rights requests, please use the email for the relevant App:

Please mention “Privacy” in your subject line for fastest routing.

18. Acknowledgement

By using Saras Educator, Charaka, Charaka NEET PG, or Charaka NEET MDS you acknowledge that you have read and understood this Privacy Policy.

Plain-English summary:

Saras Educator, Charaka, Charaka NEET PG, and Charaka NEET MDS run locally on your iPhone. Your practice data stays on your device, in a separate sandbox per app. We have no server, no account, no email list, and no analytics. The only things that leave your device are: (a) anonymous ad requests to AdMob (in all apps, configured non-personalised, no IDFA, no tracking), and (b) for Saras Educator (one-time), Charaka (NEET-UG) (₹299/month subscription), Charaka NEET PG (₹299/month subscription), and Charaka NEET MDS (₹299/month subscription), an anonymous Remove Ads receipt from Apple. You can stop everything by uninstalling.
