Tdapps built the Geometry Calculator app as a free, ad-supported application. This Privacy Policy explains what information is collected, how it is used, and the choices available to users when using the application.
By using Geometry Calculator, you acknowledge the practices described in this Privacy Policy.
Geometry Calculator provides an optional in-app feedback feature.
When you choose to submit feedback, the following information is sent to and stored in Google Firebase Cloud Firestore:
The feedback message you enter
The date and time of submission
App version and version code
Android version
Device manufacturer and model
Device language and locale
Submitting feedback is optional, and you can continue using the application without providing feedback.
The app does not ask for your name, email address, phone number, or account information when submitting feedback. However, any personal information you voluntarily include in the feedback message will be stored as part of that message. Please do not include passwords, financial information, health information, or other sensitive personal information in your feedback.
Feedback information is used to understand user suggestions, investigate reported problems, improve the application, and provide support.
The application uses Google Analytics for Firebase to understand how the application is used and to improve its features.
Google Analytics for Firebase may automatically collect information such as:
App interactions and usage events
App version
Device type and operating system
General geographic information derived from the IP address
App instance and device identifiers
App launches, updates, and engagement information
This information is generally aggregated and is not intended to directly identify you.
The application uses Firebase Crashlytics to detect crashes and improve application stability.
Firebase Crashlytics may automatically collect:
Crash logs and stack traces
Application state at the time of a crash
Device model and operating system
App version
Diagnostic and performance information
A Crashlytics installation identifier
This information is used to investigate errors, fix crashes, and improve application performance.
Geometry Calculator uses Google Mobile Ads, including banner and interstitial advertisements.
Google Mobile Ads may automatically collect or process:
IP address, which may be used to estimate general location
Advertising identifiers, app set identifiers, and other device identifiers
Advertisement views, clicks, and other interactions
App and device information
Diagnostic and performance information
This information may be used to display and measure advertisements, prevent fraud and abuse, and, where permitted by applicable law and user consent, personalize advertisements.
You can manage or delete your advertising ID through your Android device’s privacy or advertising settings.
The application uses Firebase App Check with Google Play Integrity to protect its backend services from unauthorized access, automated abuse, and fraudulent requests.
These services may process app and device metadata, Firebase SDK information, and integrity tokens to verify that requests originate from a legitimate application installation.
The collected information may be used to:
Provide and maintain the application
Receive and evaluate user feedback
Diagnose technical problems and crashes
Improve application features and performance
Understand application usage
Display and measure advertisements
Protect the application and backend services from fraud and abuse
Comply with legal obligations
Geometry Calculator uses services provided by Google, including:
Google Play Services
Google Mobile Ads
Google Analytics for Firebase
Firebase Crashlytics
Firebase Cloud Firestore
Firebase App Check
Google Play Integrity
These providers may process information on behalf of Tdapps or for their own advertising, measurement, security, and service-delivery purposes, subject to their respective policies.
For more information, please review:
Information may be processed or stored on Google infrastructure located outside your country. Where required, applicable safeguards are used for international data transfers.
Feedback submissions are retained for up to 12 months unless a longer period is reasonably necessary to investigate an unresolved issue, comply with a legal obligation, or protect the application from abuse. After this period, the feedback will be deleted or anonymized.
Retention periods for analytics, crash reports, advertising data, and security information may be determined by the applicable Google service settings and policies.
Because feedback submissions are anonymous and are not linked to an account, identifying a particular submission may not always be possible. To request deletion of a feedback submission, contact us at geocalculatorcontact@gmail.com and provide the approximate submission date and enough of the message content to locate it.
We use reasonable technical and organizational safeguards to protect collected information. Data transmitted to Firebase and Google services is encrypted in transit.
However, no method of transmission or electronic storage is completely secure, and absolute security cannot be guaranteed.
Depending on your location, you may have rights regarding your personal information, including the right to request access, correction, or deletion.
You may:
Choose not to submit feedback
Manage advertising and privacy preferences through your device settings
Reset or delete your Android advertising ID
Manage consent choices when a consent message is presented
Contact us to request information about or deletion of data associated with you
Requests can be sent to geocalculatorcontact@gmail.com
Geometry Calculator is not directed to children under the age of 13. Tdapps does not knowingly collect personal information from children under 13.
If you are a parent or guardian and believe that a child has submitted personal information through the application, please contact us at geocalculatorcontact@gmail.com so that we can take appropriate action.
The application may contain links to external websites or services that are not operated by Tdapps. We are not responsible for the content, privacy policies, or practices of those third-party services. Users are encouraged to review the privacy policy of any external service they visit.
This Privacy Policy may be updated from time to time. Changes will be published on this page, and the “Last updated” date will be revised accordingly.
Users are encouraged to periodically review this Privacy Policy.
