1. Who we are and scope
This Privacy Policy applies to the Calculator for Everything Android application and the related website operated by DurCorps. Privacy questions may be sent to durcorps@gmail.com.
2. Data you enter into calculators
Values entered into calculator fields are used to generate the requested result. Core calculation data is generally processed locally on your device and is not intentionally transmitted to DurCorps. Depending on the app version and the tool you use, preferences, favorites, recent calculations or similar convenience data may be stored locally on your device.
Some tools may use external reference data, such as currency or other changing reference values. When a feature connects to an external service, that provider may receive ordinary network information such as your IP address, device/browser information and request metadata. Do not enter confidential, medical, financial-account, authentication or other sensitive personal information into calculator fields unless a feature clearly requires it.
3. Advertising, consent and device information
The app may include Google Mobile Ads and Google User Messaging Platform (UMP). Depending on your region, consent choices, device settings and whether personalized advertising is permitted, Google and its advertising partners may process data such as IP address, advertising or app identifiers, approximate location derived from IP, app interactions, ad impressions/clicks, diagnostics and fraud-prevention signals.
Where consent is required, the app may present a consent or privacy-choice interface. You can change eligible advertising/privacy choices through the in-app privacy controls when available or through relevant device/Google settings.
4. Google Play purchases
Purchases or subscriptions, if offered, are processed through Google Play Billing. DurCorps does not receive your full payment-card details. Google may provide purchase status, product identifiers, purchase tokens or similar transaction metadata needed to activate, verify, restore or support a purchase.
5. Website, email and support communications
This website is designed to work as a static website and does not require a DurCorps user account. If you email us, we process your email address, message content and any information you voluntarily provide in order to answer your request. The hosting or network provider may automatically record standard server/security logs such as IP address, requested URL, browser/user-agent, date/time and security events.
6. Purposes of processing
- Provide calculator, converter and utility functions.
- Remember local preferences and improve usability.
- Display and measure advertising where enabled.
- Manage consent and privacy choices where required.
- Process or restore Google Play purchases.
- Answer support, privacy and data-deletion requests.
- Protect the app, website, users and services against abuse, fraud or security threats.
7. Sharing and third parties
DurCorps does not sell calculator inputs to advertisers. Data may be processed by third-party providers that support app distribution, advertising, consent, purchases, hosting or security. These providers process data under their own terms and privacy notices. Key services may include Google Play, Google Mobile Ads and Google UMP.
8. Data retention
Locally stored app data remains on your device until you clear app data, use an available in-app deletion/reset function, or uninstall the app. Support emails and related correspondence are retained only as long as reasonably necessary to respond, maintain security records, resolve disputes or satisfy legal obligations. Third-party providers apply their own retention periods.
9. Security
We use reasonable organizational and technical measures appropriate to the nature of the service. However, no device, network, internet transmission or storage system can be guaranteed to be completely secure.
10. International processing
Third-party providers may process data in countries other than the country where you live. Where applicable, those providers are responsible for using legally recognized transfer mechanisms and safeguards.
11. Your choices and rights
Depending on your location, you may have rights to request access, correction, deletion, restriction or objection concerning personal information controlled by DurCorps. You may also have the right to withdraw consent where processing is based on consent. Contact durcorps@gmail.com. Requests may require reasonable verification.
12. Children
The app is a general-purpose utility and is not specifically directed to children. If you are a parent or guardian and believe a child provided personal information directly to DurCorps, contact us so we can review and, where appropriate, delete it.
13. Data deletion
See our Data Deletion page for instructions on clearing local data and requesting deletion of information controlled by DurCorps.
14. Policy changes
We may update this policy when features, laws, SDKs or data practices change. The “Last updated” date identifies the current version. Material changes may also be communicated in the app or store listing where appropriate.
