Privacy Policy

1. Who we are

PeriodiApp is an educational chemistry application developed and operated by LEBENCORE.

If you have questions about this policy or privacy matters, you can contact us at: dev.senftleben@gmail.com

2. Information we collect

PeriodiApp does not require registration or account creation.

Depending on how you use the application, we may collect or allow the collection of the following categories of information:

a) Usage and diagnostic data

We may use third-party services such as Firebase Analytics and Firebase Crashlytics to collect technical and statistical information, such as:

• in-app usage events
• interaction with features and screens
• device information
• installation or device identifiers
• performance data
• error, crash, and diagnostic logs

This information helps us improve the stability, performance, and overall user experience of the application.

b) Advertising-related data

PeriodiApp may display ads through Google AdMob, including banner ads and rewarded ads. AdMob may collect or access certain data and identifiers, depending on the device, region, and user consent status, in order to display ads, measure performance, and help prevent fraud.

c) Local app content

The application uses local storage for its internal operation, for example for chemical element data and usage settings stored on the device. In principle, this information is not directly linked to a personal account, because the app does not require login.

d) Privacy policies and informational content

We may use Cloud Firestore to host and serve the privacy policy and other informational text in different languages.

3. How we use information

We may use collected information to:

• operate and maintain the application
• display app content and features
• measure general usage and improve the experience
• detect, diagnose, and fix errors
• display ads and measure their performance
• comply with legal or regulatory obligations
• protect the security, integrity, and operation of the app

4. Advertising, consent, and user choices

PeriodiApp may display ads through Google AdMob.

Depending on your region, we may show you a privacy notice or consent form before using certain advertising features. Depending on your choice and applicable law, ads may be:

• personalized
• non-personalized
• or limited according to applicable legal or technical requirements

If we implement an in-app privacy option, you may be able to update your preferences from the relevant section.

5. Sharing with third parties

We may share information with service providers that help us operate the app, including:

• Google Firebase (for example, Analytics, Crashlytics, Firestore)
• Google AdMob / Google Mobile Ads

These third parties may process information in accordance with their own policies and terms.

We do not sell your personal data.

6. Legal basis and international scope

PeriodiApp is intended for an international audience. Depending on the user’s country or region, data processing may be based on one or more of the following:

• your consent, when required
• our legitimate interest in operating, protecting, and improving the app
• compliance with legal obligations

If the laws in your jurisdiction grant you specific rights over your data, we will make reasonable efforts to respond to valid requests in accordance with applicable law.

7. Data retention

We retain information only for as long as necessary for the purposes described in this policy or as required by applicable law.

Some third-party providers may apply their own retention periods.

8. Security

We take reasonable measures to protect information processed by the app. However, no method of electronic transmission or storage is completely secure, so we cannot guarantee absolute security.

9. Children

PeriodiApp is intended for a general audience and educational purposes. It is not specifically designed for young children and is not intended to knowingly collect personal data from minors.

If a parent or guardian believes that a minor has provided information contrary to this policy, they may contact us at dev.senftleben@gmail.com.

10. Your rights and contact

Depending on your location, you may have the right to:

• request access to certain information
