Privacy Policy

Esteban Feldman built the Chaldean Numerology Calculator app as an ad-supported app. This SERVICE is provided by Esteban Feldman at no cost and is intended for use as is.

This page informs visitors of my policies regarding the collection, use, and disclosure of information when someone uses my Service.

If you choose to use my Service, then you agree to the collection and use of information in relation to this policy. I will not use or share your information with anyone except as described in this Privacy Policy.

Information Collection and Use

The app does not require or support account creation or login of any kind. The name and birth date you enter to calculate your numerology results are processed on your device and are not collected, transmitted, or stored by me.

The app is supported by advertising rather than by collecting or selling your personal information — see the "Advertising" section below for what the ad provider collects on its own behalf.

Advertising

This app displays ads served by Google AdMob (the Google Mobile Ads SDK), which is how the app is funded and offered free of charge. To serve and measure ads, the Google Mobile Ads SDK may automatically collect information such as your device's advertising ID, IP address, device and app information (device model, operating system version, app version), general/approximate location, ad interactions (impressions, clicks), and diagnostic data used for fraud prevention.

This data is collected and processed by Google, not by me, and is governed by Google's own privacy policy. You can read how Google uses this data at policies.google.com/technologies/ads and policies.google.com/privacy.

You can opt out of personalized ads from Google at any time from your device settings (Settings → Google → Ads → Opt out of Ads Personalization on Android) or via Google's Ads Settings. Opting out means you'll still see ads, but they won't be based on your interests.

Log Data

If an error occurs in the app, diagnostic Log Data may be collected through third-party services (including the Google Mobile Ads SDK described above). This Log Data may include your device's IP address, device name, operating system version, app configuration at the time of the error, and the time and date of use.

Service Providers

The only third party this Service shares data with is Google, through the Google AdMob SDK described in the "Advertising" section above, for the purpose of serving and measuring ads. Google is obligated to handle that data under its own privacy policy and is not permitted to use it for purposes other than serving ads and improving Google's advertising products.

Security

I value your trust in providing us your Personal Information, thus we are striving to use commercially acceptable means of protecting it. But remember that no method of transmission over the internet, or method of electronic storage is 100% secure and reliable, and I cannot guarantee its absolute security.

Links to Other Sites

This Service may contain links to other sites. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by me. Therefore, I strongly advise you to review the Privacy Policy of these websites. I have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.

Children's Privacy

This app is not directed at children and is not designed to appeal primarily to children under 13. I do not knowingly collect personally identifiable information from children, and the app itself has no account, login, or data-submission features for any user. The Google AdMob integration in this app is not configured for child-directed treatment, meaning ads are not served under Google's child-directed advertising policies. If you believe a child has provided personal information through this Service, please contact me using the details below so it can be addressed.

Changes to This Privacy Policy

I may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes. I will notify you of any changes by posting the new Privacy Policy on this page.

This policy is effective as of 08/26/2026
