Privacy Policy

Last updated: September 25, 2026

1. Introduction

Welcome to Smile Apps Studio ("we," "our," or "us"). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website and use our mobile applications.

Smile Apps Studio is operated by Swaminathan L, Bengaluru, India, who is the data controller responsible for your personal data. This policy applies to our website and to all of our mobile applications published on the Apple App Store and Google Play.

2. Information We Collect

We may collect information about you in a variety of ways. The information we may collect includes:

  • Personal Data: Name, email address, and other contact information you voluntarily provide when contacting us through our contact form.
  • Usage Data: Information about how you access and use our website, including your IP address, browser type, device information, and pages visited.
  • Mobile App Data: When you use our mobile applications, we may collect device information, usage statistics, and crash reports to improve app performance. Advertising partners may also collect data as described in the Advertising section below.

3. How We Use Your Information

We use the information we collect to:

  • Respond to your inquiries and provide customer support
  • Improve and optimize our website and mobile applications
  • Send you updates about our services (with your consent)
  • Monitor and analyze usage patterns and trends
  • Detect, prevent, and address technical issues

4. Information Sharing and Disclosure

We do not sell your personal information for money. However, when you allow personalized advertising, sharing your advertising identifier and device data with advertising partners may be considered a 'sale' or 'sharing' of personal information under some US state laws. You can opt out as described in the 'Your Privacy Choices' section. We may also share information in the following circumstances:

  • Service Providers: We may share information with third-party service providers who perform services on our behalf, such as hosting, analytics, and email delivery.
  • Advertising Partners: Google AdMob and its partners, as described in the Advertising section.
  • Legal Requirements: We may disclose your information if required by law or in response to valid requests by public authorities.
  • Business Transfers: In the event of a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction.

5. Advertising

Our free apps display ads served by Google AdMob. To deliver and measure ads, Google and its advertising partners may collect and use:

  • Your device's advertising identifier (IDFA on iOS, Advertising ID on Android)
  • Your IP address and approximate location derived from it
  • Device information such as model, operating system and language
  • Information about how you interact with ads

This data may be used to show personalized ads when you allow it. Learn how Google uses this information at https://policies.google.com/technologies/partner-sites. The full list of Google's advertising partners is shown in the consent form inside our apps.

6. Your Privacy Choices

  • EEA, UK and Switzerland: before showing personalized ads, we ask for your consent through Google's consent message. If you decline, you may still see non-personalized ads. You can change your choice at any time from the app's Settings (Privacy Choices).
  • US residents: you may opt out of the 'sale' or 'sharing' of your personal information for targeted advertising through the privacy options in our apps or by emailing us.
  • iOS: we ask for permission through Apple's App Tracking Transparency prompt. You can change this at any time in Settings → Privacy & Security → Tracking.
  • Android: you can reset or delete your Advertising ID in your device settings (Settings → Google → Ads, or Settings → Privacy → Ads on some devices).

7. Data Stored on Your Device

Many features of our apps work entirely on your device. For example, learning progress, streaks, saved items, quiz results and settings are stored locally and are not sent to us. You can delete this data using in-app reset options where available, or by uninstalling the app. Some apps download content (such as lessons) from our website; our server may keep standard technical logs, including your IP address, for security and reliability. Reminders and notifications are scheduled locally on your device.

8. Legal Bases for Processing (EEA/UK)

We process personal data on the following bases: your consent (for example, personalized advertising); our legitimate interests (keeping our apps and website secure and working, fixing problems, and measuring ad performance); and compliance with legal obligations. Where we rely on consent, you can withdraw it at any time.

9. Data Retention

We keep personal information only as long as needed for the purposes described in this policy. Messages you send us are kept as long as needed to respond and for our records. Data collected by Google for advertising is retained according to Google's policies.

10. Data Security

We implement appropriate technical and organizational security measures to protect your personal information. However, no method of transmission over the Internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

11. Your Rights

Depending on your location, you may have the following rights regarding your personal information:

  • The right to access and receive a copy of your personal data
  • The right to rectify inaccurate or incomplete information
  • The right to request deletion of your personal data
  • The right to object to processing of your personal data
