Last Updated: October 23, 2026
DIGI Calculator is a land and survey calculation utility. All land calculations and unit conversions execute locally on your device in memory. We do not require account registration and do not access sensitive device permissions (such as location, storage, camera, or contacts). We use Google AdMob to serve banner advertisements in compliance with Google Play Developer Policies and provide an optional feedback form.
This Privacy Policy applies to the Android application DIGI Calculator (referred to as "the App", "we", "us", or "our"), distributed under package name com.digicalculator.app.

All calculations performed within the App—including Acre–Guntas addition/subtraction, area conversions (Acres, Guntas, Cents, Gajam/Sq. Yards, Sq. Feet, Hectares, Bighas), length conversions, and 7 geometric shape area formulas—are processed strictly in memory on your device.
The App does not save your land measurements or calculation history to a local database (SQLite/Room) or file system.
Your land calculations are never transmitted over the internet or logged to any server.
When you close or clear the screen, your entered dimensions and calculation results are cleared from memory.
The App includes an optional Feedback & Support feature allowing users to submit bug reports, calculation suggestions, and app ratings. We collect data only when you explicitly tap "Submit Feedback". If you do not submit feedback, no data is collected or sent.

Feedback submissions are processed and stored on our cloud backend hosted by Supabase (Supabase Inc.).
Submissions are sent directly to our Supabase database table (public.app_feedback) over encrypted HTTPS connections.
Strict Row Level Security (RLS): The database enforces Row Level Security. Public and anonymous read access (SELECT) is strictly denied. No user can read, browse, or query feedback submitted by other users.
The Android client uses a public, publishable anonymous API key with restricted permissions. No administrative or service_role keys are embedded in the app.
The backend is Supabase, not Google Firebase. No Firebase services or databases are integrated.
The App displays banner advertisements powered by Google AdMob (Google LLC). To serve ads safely and comply with Google Play Developer policies:
Google Mobile Ads SDK may collect device identifiers (such as Android Advertising ID / AAID) and coarse network data to deliver, measure, and protect against fraud in ad serving.
User Messaging Platform (UMP): For users located in the European Economic Area (EEA) and the UK, we use Google's User Messaging Platform to gather user consent in compliance with the General Data Protection Regulation (GDPR) and Google's EU User Consent Policy.

Third-party libraries integrated in the App are strictly limited to:
Google Mobile Ads SDK & UMP (Google LLC): Serves adaptive banner advertisements and manages consent. Governed by Google's Privacy Policy (https://policies.google.com/privacy).
Google Play In-App Updates SDK (Google LLC): Facilitates checking for and downloading app updates directly through Google Play services.
OkHttp (Square / Block Inc.): An open-source HTTP networking client library used to transmit HTTPS feedback requests to our Supabase backend. OkHttp does not collect or transmit analytics independently.
AndroidX & Material Components (Google LLC): Standard Android user interface components and runtime libraries.
DIGI Calculator does not feature user accounts. You are not required to create a profile, username, or password to use any calculator or converter feature. Because no accounts exist, account creation and in-app account deletion mechanisms do not apply to this application.
Calculation data is never retained on disk or servers.
For feedback data submitted to Supabase:
Feedback records are retained for product improvement, debugging, and quality assurance purposes until resolved or periodically purged during database maintenance.
Deletion Requests for Identifiable Feedback: If you voluntarily provided a contact email address with your feedback submission and wish to have that feedback deleted, you may contact us at contact2rudratech@gmail.com with the subject line "Feedback Deletion Request" from that same email address. Upon verification, we will delete all feedback records associated with that email within 30 days.
Anonymous Feedback: If you submitted feedback without providing an email address, the data is completely anonymous and cannot be tied to any identifiable individual.
We protect user data using industry-standard measures:
Encryption in Transit: All data transmitted between the App and the Supabase backend or Google Play is encrypted using Transport Layer Security (TLS 1.2+ / HTTPS).
Least Privilege Access: The client application only holds permission to insert feedback. It cannot read, modify, or delete database records.
No Secret Keys Embedded: No administrative or master keys are included in the mobile application binary.
The App is a specialized agrarian and survey measurement tool intended for farmers, surveyors, land owners, and real estate professionals. The App is not directed to children under the age of 13, and we do not knowingly collect personal information from children.
We may update this Privacy Policy from time to time. Any updates will be posted to this page with an updated "Last Updated" date.
