Expense Calculator & Budget — Privacy Policy

In short: your expenses, budgets and photos stay on your phone. They leave it only if you turn on Google Drive backup (to your own Drive) or export/share a file yourself. The app is free and shows ads from Google AdMob.

Expense Calculator & Budget (package com.gauravkr.expensecalculator, "the app") is developed by Gaurav Kumar, Gemini Digital Solutions ("we", "us"). This policy explains what the app does with your information.

1. Your expense data

Everything you enter — accounts, categories, budgets, expenses, notes, and optional bill or account photos — is stored in the app's private storage on your device. Other apps cannot read it. We never receive, sell or share it, and it is never sent to advertisers.

You can delete individual items, whole accounts, or everything (Settings → Erase all data). Uninstalling the app also deletes all of its data.

2. Google sign-in and Drive backup (optional)

If you turn on Google Drive backup, you sign in with your Google account and the app reads your name and email address to show which account is connected.

Backups — your accounts, categories, budgets, expenses, notes and settings, not bill photos — are uploaded over an encrypted connection to a private app folder (appDataFolder) in your own Google Drive. Only this app can access that folder; the app cannot see or change your other Drive files. We never receive a copy.

Automatic backups (hourly, daily or weekly) run only while you use the app and only when something changed. You can back up or restore manually, delete the backup (Settings → Google Drive backup → Delete backup from Drive), sign out, or remove the app's access at myaccount.google.com/permissions.

3. Advertising (Google AdMob)

Apart from optional Drive backup, the app connects to the internet only to show a banner ad. Ads are served by Google AdMob, which may automatically collect and use:

• your device's advertising ID and other device identifiers,
• your IP address, from which an approximate location may be derived,
• information about ad views and clicks, and app performance and crash data related to ads.

Google uses this to deliver, personalise and measure ads and to prevent fraud. See how Google uses information from apps that use its services.

Your choices: in the EEA, UK and Switzerland you are asked for consent before personalised ads are shown, and you can change it anytime in the app (Settings → Ad privacy choices). Everywhere, you can reset or delete your advertising ID, or opt out of personalised ads, in your phone's Settings → Privacy → Ads. Ad content is limited to material suitable for a general audience.

4. Camera and photos

If you attach a bill or set an account picture, the app opens your camera app or the Android photo picker. Only the photos you pick are copied into the app's private storage. The app cannot see the rest of your gallery and requests no storage permission.

5. Export, import and sharing

When you export, back up to a file, or share, the app creates a file (CSV or JSON) or a text summary and hands it to the app you choose (Files, Drive, email, a messaging app…). From then on, that app's privacy policy applies. When you import or restore a file, the app reads only the file you pick.

6. App lock

If you turn on the PIN lock, only a hashed form of your PIN is stored on your device.

7. Permissions

Permission	Why
Internet, network state	Loading ads; optional Google Drive backup
Advertising ID	Used by Google AdMob, as described above
Vibrate	Short feedback when a wrong PIN is entered

8. Children

The app is not directed at children under 13.

9. Your rights

Your expense data is on your device and under your control: you can view, export, correct or delete it in the app at any time. For Drive backups, use the controls described in section 2. For advertising data held by Google, use your device's ad settings or My Ad Center. If you have a privacy request or question under GDPR, UK GDPR, CCPA/CPRA, DPDP or any other law, email us.

10. Changes

If this policy changes, the updated version will be published on this page with a new "Last updated" date.
