Privacy policy for Montari Invoice

Last updated: 9 October 2026

This policy covers the app Montari Invoice for iPhone and Android (bundle and package name nl.montari.invoice), published by Montari, Apeldoorn, the Netherlands. For the website montari.nl a separate privacy statement applies (in Dutch).

In short

Montari Invoice works without an account and without a server of ours. Everything you enter stays on your own phone. We cannot see your invoices, your clients or your photos. Data only leaves your device when you share something yourself, for example a PDF to your client or a backup file to your own storage.

What the app stores

You enter the data yourself. This can include:

  • Business details such as business name, address, tax ID, payment instructions, logo and signature.
  • Client details such as name, address, email address, phone number and tax ID.
  • Documents such as invoices, estimates and receipts with their lines, prices, taxes, payments, notes, photos and signatures.
  • Saved items such as product and service names and prices.

All of this is stored in the app’s private storage on your device.

What happens to that data

The app does not send this data to us or to third parties. There is no Montari account, no Montari server, no advertising network, no analytics and no crash reporting in the app, and the app does not track you across other apps or websites.

Data leaves your device only when you choose to:

  • You share a document as a PDF, for example by email or a messaging app. You choose the recipient.
  • You export a CSV file and share it, for example with your accountant.
  • You save a backup file and store or share it yourself.

Phone backups

Your phone’s own backup may include the app’s data, so it can be restored on a new phone. That backup is handled by the maker of your phone’s operating system under its own privacy policy and your backup settings; we have no access to it.

  • On iPhone:if iCloud Backup or a backup to your computer is turned on, it can include the app’s data. Apple handles that backup.
  • On Android:the app allows Android’s built-in backup. If backup to your Google account is turned on, it can include the app’s data. Google handles that backup.

You can turn these backups off in your phone’s settings.

Subscriptions and payments

You can subscribe to Montari Invoice Pro in the app. Payment is handled by the app store you installed the app from: Apple through the App Store on iPhone, and Google Play Billing on Android.

  • We do not process payments and never see your payment details. Your payment method and transactions are handled by the app store under its own privacy policy.
  • The app asks the app store whether a subscription is active on your account there. The answer is only whether Pro is active; no personal details. The app keeps that answer on your device only.
  • Without a subscription you can always open, share and back up the documents you made. Your data is never locked behind a paywall.

Permissions

The app never asks for your microphone, contacts or location.

  • On iPhone: the camera is used only when you choose to take a photo for your logo or a document, and your iPhone asks your permission first. When you pick an existing photo instead, the system photo picker gives the app only the image you choose.
  • On Android:internet, network state and Google Play Billing are technically required by the app framework and for subscriptions. These are normal permissions that Android grants without asking. There is no camera permission: when you add a logo or photo, Android’s own picker opens and gives the app only the image you choose.

The app itself does not send your data anywhere.

Retention and deletion

You decide how long you keep your data. You can delete documents, clients and items in the app. Uninstalling the app removes its data from your device. Because we hold no copy, we cannot restore anything for you, so make a backup now and then. You are responsible for any legal obligation to keep your business records.

Your role and ours under the GDPR

Your clients’ data is stored only on your device and we have no access to it, so you are the controller of that data. We only provide the software and do not process your clients’ personal data.

Children

Montari Invoice is a business app and is not directed at children.

Changes

If the app changes, for example if an account or sync feature is added, we will update this policy before that feature goes live.
