Privacy policy

Last updated: 23 October 2026

In short: your business details, customers and invoices stay on your phone. There is no account and no cloud sync. Nothing you enter about your business, customers or invoices is sent to us or to an AI service, except what you say with voice typing, which Google or Apple may process (see “Voice typing” below).

Who we are

Simple Smart Invoice (“the app”) is published by its developer in Australia (“we”, “us”). Contact: simplesmartinvoice@gmail.com.

What the app keeps, and where

Everything you enter — your business details and logo, bank or PayID details, customers, invoices and their PDFs, saved items, your translations and settings — is stored only on your phone, in the app's private storage. We have no server that receives it, and we never see it.

A backup password you choose or the app makes is kept in your phone's secure storage (Android Keystore or iPhone Keychain). It never leaves your phone.

When the app uses the internet

Only for the following, and only when you use them:

• Translation packs. The first time you translate from Chinese, Japanese or Korean, the app asks before downloading a language pack using Google ML Kit. Translation itself happens on your phone; your words are not sent to Google. Google's ML Kit component may send Google anonymous statistics about how it performs, under Google's privacy policy.
• Fonts. If an invoice contains Chinese, Japanese or Korean characters, the app asks before downloading a matching font (from Google Fonts or our own website). Only the font file is requested; nothing about your invoice is sent.
• Voice typing. Uses your phone's speech recognition (Google on Android, Apple on iPhone). The app asks it to work on the phone where supported, but depending on your phone your voice may be processed by Google or Apple under their privacy policies.
• ABN lookup. Opens the Australian Government's ABN Lookup website in your browser.
• Sharing. Invoices, backups and exports go only to the app you choose (for example email or Google Drive), under that app's terms.
• Subscription. Purchases are made through Apple or Google. The app uses RevenueCat to check whether a subscription is active: RevenueCat receives a random ID made by the app, your purchase records from Apple or Google, and basic device details sent with each check (such as the phone's system version, the app version and your internet address) — not your name, your business or your invoices. See RevenueCat's privacy policy.
• Partner code (Android). If you type a partner code, only the code is sent to our server to check it. We store nothing about you; our hosting provider (Supabase) keeps routine technical logs, such as the internet address, for a short time.

The app has no advertising and no analytics of its own, and it does not track you. (Google's translation component sends Google anonymous statistics about how it performs: see “Translation packs” above.)

Backups

The app's own backup is encrypted on your phone with your password (Argon2id and ChaCha20-Poly1305) before you share it, so wherever you keep it — Google Drive, iCloud, email — only someone with the password can open it. We can't recover a lost password. Opening and restoring a backup happens on your phone; nothing is sent to us.

Your phone may also back up app data itself: on Android 9 or later with a screen lock, Android may back up the app's records and logo to your Google account (end-to-end encrypted); iPhone iCloud and computer backups include the app's data (end-to-end encrypted only with Advanced Data Protection). You control these in your phone's settings.

Permissions

• Microphone — only if you use voice typing, and asked at that moment.
• Photos / files — only through the system picker, when you choose a logo or a backup file.
• Internet — for the downloads described above.

Deleting your data

Deleting the app deletes all its data from your phone. Make a backup first if you need your records: Australian businesses generally need to keep business records for at least 5 years.

Children

The app is a business tool and is not directed at children.

Changes

If this policy changes, we will update this page and the date above, and say so in the app where the change matters to you.
