Privacy Policy
for US Loan & Mortgage Calculator
Effective Date: 17 March 2026
Last Updated: 17 March 2026
Introduction
US Loan & Mortgage Calculator (“the app”) is a free personal
finance application that provides tools to estimate mortgage payments,
loan amortization, investment growth, retirement savings and take‑home
salary. This privacy policy explains what information the app collects
and how that information is used, shared and protected. By installing or
using the app you agree to the practices described herein. If you do not
agree with this policy, please do not use the app.
Data We Collect
- Calculator Inputs. When you use one of the
calculators, you enter data such as loan amount, interest rate, loan
term, investment contributions, retirement age or salary details. This
information stays on your device and is used only to perform
calculations. We do not require you to create an account or enter
personally identifiable information (such as name, email address or
phone number) to use the app.
- PDF Export. Some calculators allow you to export
results to a PDF file. To save the file, the app requests permission to
write to your device’s storage. The permission is used solely to create
the report in your downloads folder; the app does not read, modify or
upload other files.
- In‑app Purchase Tokens. When you purchase the
optional ad‑free version, Google Play may provide us with a purchase
token or order ID. We store this token on your device to verify your
purchase and unlock premium features. The token does not include your
payment details or personal information.
- Analytics and Diagnostics. The app integrates
Google’s Firebase Analytics and related services to measure usage and
diagnose issues. According to Google’s documentation, Google Analytics
for Firebase may collect device identifiers such as a mobile advertising
ID, IDfV (on iOS), Android ID, instance ID and analytics app‑instance
ID. Firebase services also collect device information and app usage
data (e.g., which screens are viewed). This data is used in aggregate
to understand how users interact with the app, to troubleshoot problems
and to improve the app’s features. We do not use Firebase Analytics to
identify individual users, and we do not log personally identifiable
information.
- Advertising Data. To keep the app free, we display
banner and interstitial advertisements using the Google Mobile Ads SDK
(AdMob). Google’s SDK automatically collects and shares certain end‑user
data—including IP address, user interaction information, diagnostic data
and device or account identifiers—for advertising, analytics and
fraud‑prevention purposes. This includes collecting the Android
advertising ID, app‑set ID and other identifiers associated with
signed‑in accounts. All data sent through the SDK is encrypted in
transit using Transport Layer Security (TLS). Users can reset or delete
the Android advertising ID or limit ad personalisation via their device
settings.
- Cookies and Similar Technologies. Advertising
partners and analytics providers may use cookies or similar technologies
to personalise ads and measure campaign performance. These technologies
are controlled by the third‑party providers; we do not directly access
cookie data.
3. Permissions
The app requests only the permissions necessary to operate:
- Storage/Files: Needed to save PDF reports generated
from your calculations. The app does not access other files on your
device.
- Internet: Required to load ads and send anonymised
analytics and diagnostic data to Firebase and the ad network.
- Billing: We request the
com.android.vending.BILLING permission so that you can
purchase the ad‑free version through Google Play’s billing system. We
do not use this permission for any other purpose.
The app does not request access to your location, contacts, camera or
microphone.
How We Use Your Data
- Providing Calculator Functions. The numerical
inputs you provide are used locally on your device to calculate
results. We do not transmit or store this data on our servers.
- Analytics and Improvement. Aggregated analytics
data from Firebase helps us understand which calculators are most
useful and identify errors so we can improve functionality. We may also
use analytics to monitor app performance and stability.
- Advertising. We work with ad networks to display
ads in the app. Advertising partners may use collected data (such as
device identifiers and interaction data) to deliver and measure
personalised or contextual advertisements. We do not control or access
the data collected by these partners.
- Processing Purchases. When you purchase the
ad‑free version, Google Play handles the payment process. We use the
purchase token supplied by Google to verify your entitlement, remove
ads and provide customer support. We do not process payments ourselves
or store your full financial information.
- Compliance and Protection. We may use or disclose
information if required by law, to enforce our terms, or to protect the
rights, property or safety of users and the public.
Data Sharing
We do not sell or rent your personal information. We share limited
data with third‑party service providers only to the extent necessary to
provide our services:
- Google Firebase. We share anonymous usage data with
Firebase for analytics purposes. Firebase may collect device
identifiers and usage information. Google’s terms require developers
to disclose which Firebase services they use, abide by privacy laws and
provide a compliant privacy policy.
- Advertising Partners. Data collected by the Google
Mobile Ads SDK (IP address, device identifiers, user interactions and
diagnostics) is shared with Google and its advertising partners. This
information is used for ad selection, performance measurement and
fraud detection. We do not receive the raw data collected by these
partners.
- Google Play Billing. For in‑app purchases, your
payment information (such as credit or debit card details) is handled
directly by Google Play or its payment processors. We do not receive
your full payment details. We may receive a purchase token or order ID
from Google to confirm your purchase. This token does not contain
personally identifiable financial data and is used only to enable
premium features.
- Aggregated Data. We may share aggregated,
anonymised statistics (for example, total number of app downloads or
popularity of specific calculators) with partners or the public. These
statistics do not identify individual users.
Data Retention
- User Inputs. Input data you enter in the
calculators is not stored on our servers and is cleared when you exit
the calculator or close the app.
- Analytics and Advertising Data. Firebase Analytics
and advertising networks retain data according to their own retention
policies. We do not have direct control over these retention periods.
We retain only aggregated analytics reports as long as necessary to
improve the app.
- Purchase Tokens. We retain purchase tokens or
order IDs provided by Google Play as long as necessary to verify your
entitlement to the ad‑free version and provide support. These tokens are
stored on your device or securely in our servers, if applicable, and are
not used for any other purpose.
Children’s Privacy
The app is not directed to children under 13 and we do not knowingly
collect personal information from children. If a parent or guardian
becomes aware that a child under 13 has provided personal information,
please contact us so we can delete the information.
International Users
Although the app is intended for users in the United States, it may
be downloaded globally. Data collected by Firebase, AdMob and Google
Play Billing may be transferred to and processed on servers located in
the United States or other countries in which Google and its service
providers maintain facilities. Google states that user data is
encrypted in transit using TLS.
Your Choices
- Reset Advertising ID or Limit Personalised Ads. You
can reset the Android advertising ID or limit personalised ads in your
device’s settings.
- Analytics Opt‑Out. Some devices allow you to limit
analytics collection. You can also follow Google’s instructions for
opting out of Firebase Analytics collection.
- Control of Inputs. You may choose not to enter data
into the calculators, though this will prevent the calculators from
providing results. You can delete generated PDF reports at any time via
your device’s file manager.
- Manage Purchases. You can review and manage your
in‑app purchases, restore purchases and request refunds through your
Google Play account settings. Google’s support pages provide detailed
instructions on how to view order history and request refunds.
- Data Deletion. Because we do not store your personal information on our servers and analytics and advertising data is collected and retained by third‑party providers (such as Google Firebase, Google Mobile Ads and Google Play Billing), we cannot delete that data on your behalf. If you wish to remove any data associated with your Google Play account or advertising ID, please follow the deletion or reset instructions provided by Google and other service providers.
Security
We implement reasonable technical and organisational measures to
protect the information transmitted through the app. Data sent via
Firebase, the Google Mobile Ads SDK and Google Play Billing is
encrypted in transit using TLS. However, no method of transmission or
electronic storage is completely secure; therefore we cannot guarantee
absolute security.
Links to Other Sites
The app may contain links to external websites or resources (for
example, our support email address). These links are provided for
convenience. We have no control over and assume no responsibility for
the content, privacy policies or practices of any third‑party sites or
services. We encourage you to review the privacy policies of those sites
before providing them with any personal information.
Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we
will revise the “Last Updated” date at the top of the policy. If the
changes are material, we will notify you via the app or other
appropriate channels. Continuing to use the app after an update
constitutes your acceptance of the revised policy.
If you have any questions or concerns about this Privacy Policy, or
if you wish to exercise any of your rights under applicable data
protection laws (such as requesting access to or deletion of your data),
please contact us at contact.jostech@gmail.com. We will
respond as required by law and within a reasonable timeframe.
Disclaimer
The calculators in this app are provided for informational purposes
only and should not be considered financial, tax or legal advice. While
we strive to ensure the accuracy of the results, errors may occur.
Always consult a qualified professional before making any financial
decisions based on the calculator outputs.
