Privacy Policy — Science Cal
Effective Date: July 26, 2026. Last Updated: July 26, 2026
This Privacy Policy describes how Purohit Moshai ("we," "us," "our," or "Developer") collects, uses, discloses, and protects information in connection with the Science Cal mobile application (the "App"), available on the Google Play Store.
By downloading, installing, or using Science Cal, you agree to the terms of this Privacy Policy. If you do not agree, please do not use the App.
1. Information We Collect
Science Cal is designed to work primarily offline for its core calculator and reference features. We collect only the minimum information necessary to operate the App and to display advertisements.
1.1 Information You Provide
- Language, unit system, and theme preferences you select inside the App.
- Any data you voluntarily enter into calculators (this data is processed locally on your device and is not transmitted to our servers).
- If you contact us via email for support, we receive your email address and the contents of your message.
1.2 Information Collected Automatically
Through our use of third-party services (see Section 3), the following information may be collected automatically:
- Advertising Identifier (Google Advertising ID / AAID)
- Device information (device model, operating system version, screen resolution, language settings)
- App usage data (screens viewed, calculators used, session length, crash and performance diagnostics)
- Approximate location derived from IP address (for ad relevance; not precise GPS location)
- IP address
We do not collect your name, phone number, precise location, contacts, photos, or any other sensitive personal data unless you voluntarily provide it to us via email.
2. How We Use Your Information
We use the information collected for the following purposes:
- To operate, maintain, and improve the App's features and performance.
- To display advertisements (including personalized ads, where permitted) through Google AdMob.
- To analyze usage trends and diagnose technical issues (crash reports, bug fixes).
- To respond to your support requests and feedback.
- To comply with legal obligations and enforce our Terms & Conditions.
3. Advertising — Google AdMob
Science Cal displays advertisements to support free access to the App. We use Google AdMob, a third-party advertising service provided by Google LLC, to serve ads within the App.
- AdMob may collect and use data (such as the Advertising ID, device information, and approximate location) to show relevant ads and measure ad performance.
- Depending on your region and consent choices, ads shown may be personalized or non-personalized.
- You can manage your ad personalization settings, opt out of interest-based ads, or reset your Advertising ID at any time via your device settings:
- Android: Settings → Google → Ads → Opt out of Ads Personalization / Reset Advertising ID.
- Google's use of advertising data is governed by the Google Ads Data Processing Terms and Google's own Privacy Policy: https://policies.google.com/privacy
- For more on how Google uses data from apps that use its services, see: https://policies.google.com/technologies/partner-sites
We do not control the specific ad content shown to individual users; ad selection is managed by Google's AdMob systems.
4. Third-Party Services
Science Cal may use the following third-party services, each with its own privacy policy:
| Service | Purpose | Privacy Policy |
|---|---|---|
| Google AdMob | Advertising | https://policies.google.com/privacy |
| Google Play Services | App distribution, licensing, security | https://policies.google.com/privacy |
| Firebase (if enabled) | Crash reporting & analytics | https://firebase.google.com/support/privacy |
These third parties may independently collect information as described in their respective privacy policies. We encourage you to review them.
5. Data Storage and Local Processing
- Calculator inputs, favorites, and history are stored locally on your device using local storage (SharedPreferences/Hive) and are not uploaded to our servers.
- Uninstalling the App will permanently delete all locally stored data.
- We do not operate a backend server that stores your personal calculator data.
6. Data Sharing and Disclosure
We do not sell your personal information. We may share limited information only in the following circumstances:
- With service providers (e.g., Google AdMob) strictly to operate advertising and app functionality.
- If required by law, legal process, or governmental request.
- To protect the rights, property, or safety of Purohit Moshai, our users, or the public.
- In connection with a merger, acquisition, or sale of assets (users will be notified of any material change).
7. Children's Privacy
Science Cal is intended for a general audience, including students, and is not directed exclusively at children under 13 (or the applicable age of consent in your country).
- We do not knowingly collect personal information from children in a manner inconsistent with the Children's Online Privacy Protection Act (COPPA) or Google Play's Families Policy.
- If our App is designated as suitable for children or mixed audiences, advertisements shown to users identified as children will be limited to non-personalized ads in accordance with Google Play policy.
- If you believe a child has provided us with personal information, please contact us at the email below so we can promptly delete it.
8. Your Rights and Choices
Depending on your location, you may have rights under applicable data protection laws (such as the GDPR in the EU/EEA, UK GDPR, or the CCPA/CPRA in California), including the right to:
- Access the information we hold about you.
- Request correction or deletion of your data.
- Object to or restrict certain processing.
- Withdraw consent for personalized advertising at any time.
- Lodge a complaint with your local data protection authority.
To exercise any of these rights, contact us using the details in Section 12. Since Science Cal stores most data locally on your device, you can also exercise many of these rights directly by clearing app data or uninstalling the App.
9. Data Retention
- Locally stored data remains on your device until you clear it or uninstall the App.
- Advertising and analytics data collected by Google AdMob is retained according to Google's own retention policies.
- Support emails are retained only as long as necessary to resolve your inquiry.
10. Data Security
We take reasonable technical and organizational measures to protect information from unauthorized access, alteration, disclosure, or destruction. However, no method of electronic storage or transmission is 100% secure, and we cannot guarantee absolute security.
11. International Data Transfers
If you use Science Cal outside your home country, your information (including data processed by Google AdMob) may be transferred to, stored, and processed in countries other than your own, including the United States, in accordance with applicable data protection safeguards.
