Scale Invoice Privacy Policy
- Your business records (invoices, estimates, customers, items, payments) are stored only on your phone. We have no server, and the app sends them nowhere.
- There is no account and no login. We don't ask for your name, phone number or email.
- On the Free plan, the app shows ads from Google AdMob. AdMob collects some device information, such as your advertising ID, to show and measure ads. Your business records are never shared with it.
- The Growth subscription is sold through Google Play. Google takes the payment; we never see your card, UPI or bank details.
- We advertise the app on Facebook and Instagram. To count installs from those ads, the app tells Meta when it is installed and opened, with your advertising ID and device information. Nothing you enter is ever sent to Meta.
- The app uses the internet only for ads, for checking your subscription with Google Play, and for measuring installs from our own ads.
1. What you enter, and where it stays
To make invoices you enter information about your business and the people you sell to. All of it is saved in a database on your phone:
- Your business: name, address, state, GSTIN, PAN (worked out from the GSTIN), turnover band, UPI ID, bank details, and your logo and signature if you add them.
- Your customers and suppliers: names, phone numbers, GSTINs, addresses, opening balances.
- Your items, invoices, estimates, bills, payments and stock, and the invoice design you choose.
The app does not send this information to us, to Google AdMob, to Meta, or to anyone else. We cannot see it, and we cannot recover it for you if it is lost.
App lock
If you turn on app lock, your PIN is stored only as a one-way hash in your phone's secure storage. Fingerprint and face unlock are handled by Android; the app never receives your fingerprint or face data. The PIN is never backed up and never leaves the phone.
When you share
An invoice, estimate, statement, sales report, backup file or payment reminder leaves your phone only when you tap Share, Print or Copy and choose where it goes (for example WhatsApp, email, Google Drive or a printer). What happens next is governed by the app or service you chose.
Android backup
If Android backup is on for your phone, Android may back up the app's database and your logo and signature to your own Google account, so they come back on a new phone. This backup is run by Google under your Google account, not by us. Your app-lock PIN and your subscription status are never included. You can turn backup off in your phone's settings.
2. Ads on the Free plan (Google AdMob)
On the Free plan the app shows ads from Google AdMob, a Google service, in a few places (banners on the main lists, and at most an occasional full-screen ad after saving an invoice). To choose and measure ads, prevent fraud and fix problems, the AdMob software in the app collects and sends to Google:
- your device's advertising ID;
- your IP address, from which Google may estimate an approximate location (city or region, not GPS);
- device information: model, Android version, language and the app's version;
- how you interact with ads: which ads were shown and whether you tapped them;
- diagnostics about the ads software, such as crashes.
AdMob never receives your invoices, customers, amounts or any other record you enter. Where the law requires your consent (for example in the EEA, the UK and some US states), the app asks first, through Google's consent form, and you can change your choice later in Menu → Privacy & ads. You can reset or delete your advertising ID, or opt out of personalised ads, in your phone's Settings → Google → Ads.
Google's use of this information is described in its privacy policy (policies.google.com/privacy) and in how Google uses information from sites or apps that use its services.
With the Growth subscription, the ads software is not started at all, so AdMob collects none of this. Install measurement (section 3) still runs.
3. Measuring installs from our ads (Meta)
We advertise Scale Invoice on Facebook and Instagram. To learn which of those ads lead to installs, the app includes Meta's software (the Meta SDK). It tells Meta when the app is installed, and each time it is opened and closed. With these events the Meta SDK collects and sends to Meta:
- your device's advertising ID;
- your IP address, from which Meta may estimate an approximate location (city or region, not GPS);
- device information: model, Android version, language, time zone, mobile network and the app's version;
- the install referrer from Google Play: which ad or link, if any, led to the install;
- when the app was opened and closed;
- diagnostics about the Meta SDK itself, such as its own crashes.
The app sends Meta nothing else. Your invoices, customers, items, amounts, purchases and anything you type never go to Meta, and the app logs no other events. Meta may combine this information with other information it has, and use it to measure and improve our ads, to show ads (including on Facebook and Instagram) and to keep its services secure, as described in Meta's Privacy Policy (facebook.com/privacy/policy). Install measurement runs on the Free plan and with Growth, because it measures our own advertising, not ads in the app.
To limit it: reset or delete your advertising ID in your phone's Settings → Google → Ads, so Meta can't link the app to it. If you use Facebook or Instagram, you can see and disconnect what Meta receives from apps in Accounts Centre → Your information and permissions → Your activity off Meta technologies.
4. The Growth subscription (Google Play Billing)
Growth is an optional subscription sold through Google Play. Google Play handles the purchase, the payment and cancellations under your Google account and Google's terms. We never receive your card, UPI, bank or other payment details.
Google Play tells the app whether your subscription is active. The app keeps, on your phone only, which plan you have and when Google Play last confirmed it, so Growth keeps working for a while if you are offline. Each purchase carries a random code made on your phone for Google's fraud checks; it does not identify you, and we cannot link it to you. As for every app on Google Play, Google gives us order records for sales (such as the order number, plan, price, date, and the buyer's country and state for tax). We use them only for our accounts and to help you if you contact us about a purchase.
5. What we collect
| Data | Collected? | Notes |
|---|---|---|
| Invoices, estimates, customers, items, payments, business details | No | Stored only on your phone. |
| Your name, email or phone number | No | There is no account. |
| App-lock PIN, fingerprint, face | No | PIN hashed on the phone; biometrics handled by Android. |
| Advertising ID, IP address, device information, ad interactions | By Google AdMob, on the Free plan only | To show and measure ads and prevent fraud. See section 2. |
| Install and app-open events, advertising ID, IP address, device information, install referrer | By Meta, on every plan | To measure installs from our own ads. See section 3. |
| Payment details | No | Handled by Google Play. See section 4. |
| Location (GPS), contacts, photos, files | No | The app never reads them. |
Google Play may give us anonymous, aggregated crash and performance statistics (Android vitals) if you have allowed your phone to share usage and diagnostics with app developers. These never include your records.
We do not sell data, and we do not build a profile of you. What Google and Meta do with the information their software collects is set out in their own privacy policies.
6. Permissions the app asks for
- Internet and network state: only to load ads on the Free plan, to check your subscription with Google Play, and to tell Meta about installs and app opens (section 3). Everything else works offline.
- Advertising ID: used by Google AdMob on the Free plan (section 2), and by Meta to measure installs (section 3).
- Install referrer: lets Google Play tell the app which ad or link, if any, led to the install (section 3).
- Google Play billing: to buy and check the Growth subscription.
- Fingerprint / face unlock: only if you turn on app lock.
- Photos: only when you choose a logo or signature image, through Android's photo picker. The app sees only the picture you pick.
The app does not ask for location, contacts, camera, microphone or phone permissions.
7. Children
Scale Invoice is a business tool for adults. It is not directed at children, and it is intended for people aged 18 and over.
8. Your choices and deleting your data
- Delete everything: use Menu → Delete all data, uninstall the app, or clear its storage in Settings → Apps → Scale Invoice → Storage. This removes all your records from the phone. We hold no copy.
- Ads and install measurement: reset or delete your advertising ID in Settings → Google → Ads; take the Growth subscription, which turns ads off; and manage what Meta receives from apps in Facebook or Instagram's Accounts Centre (section 3).
- Subscription: cancel any time in Google Play → Payments & subscriptions → Subscriptions. Your records stay yours whether you subscribe or not.
- Backup copy: remove it from your Google account's backups (Google Drive → Backups) if you don't want it restored.
Because we hold none of your records, you access, correct and delete them yourself, in the app. Your rights under India's Digital Personal Data Protection Act, 2023 are not limited by this policy.
9. Security
Your records are protected by Android's app sandbox, and by app lock if you turn it on. Anyone who can unlock your phone and open the app can see your records, so we recommend a screen lock and app lock.
10. Changes to this policy
If anything above changes, we will update this page and the effective date before the change reaches you. Version 1.1.1 added install measurement with Meta (section 3). Version 1.1 (3 October 2026) added ads on the Free plan and the Growth subscription; version 1.0 had neither.
