Invoice & Receipt Maker: Smart (“Invoice Maker”, “the app”, “we”) is published by Zintex OÜ, Ahtri tn 12, Tallinn 15551, Estonia. This policy explains what happens to your data when you use the app on iPhone or iPad. The short version: your invoices, clients and business details stay on your device; what leaves it is only what subscriptions and remote app settings need to work.
Everything you create in the app — your business profile (name, logo, email, phone, address and bank details), clients, items and services, invoices, estimates, payment status and reports — is stored locally on your device. It is not uploaded to any server of ours, and we cannot see it.
When you send or share an invoice or estimate, the app creates a PDF and hands it to the channel you choose (Mail, a messaging app, Files and so on). What happens to it after that is governed by the service you sent it through, not by us.
Deleting the app deletes all of this data. If your device backs up app data to iCloud, that backup belongs to you and is covered by Apple's privacy terms.
Subscriptions (Apple and Adapty). Subscriptions are sold and charged by Apple through the App Store. To check whether your subscription is active and to restore it on another device, the app uses Adapty (Adapty Tech Inc.), a subscription-management service. Adapty receives your App Store purchase receipt, a random identifier generated by the app (not linked to your name or email), basic device and app information (model, OS and app version, language, country/region) and your IP address as part of the network connection. We never see your name, Apple ID or payment card details.
Remote app settings (Google Firebase). The app uses Firebase Remote Config (Google LLC) to fetch a small set of settings, for example how the subscription screen behaves. To deliver them, Firebase uses an app-instance identifier and basic device and app information. No invoice content is sent.
Crash and diagnostic data. Apple may share anonymised crash reports and aggregate usage statistics with us if you have enabled sharing with app developers in your device settings. These contain no invoice content.
That is the complete list. The app has no accounts, no sign-in, no ads and no analytics or advertising SDK.
No account, no name, no email address on our side. No advertising identifier (the app does not ask for tracking permission and does not track you across other apps or websites), no contacts, no precise location. We do not show ads, we do not sell data and we do not build a profile of you.
The app uses the system photo picker when you add a business logo; only the image you pick is read. Sending an invoice by email opens the system Mail composer, which you control.
Where EU/EEA or UK data-protection law applies, purchase verification is necessary to perform the contract you enter into when you subscribe, and remote settings are processed on the basis of our legitimate interest in keeping the app working. Adapty and Google act as our processors under their data-processing terms and may process data outside the EU/EEA under appropriate safeguards such as Standard Contractual Clauses.
Data on your device is kept until you delete it or the app. Purchase and subscription records are kept by Apple and by Adapty for as long as needed to provide and verify your subscription and to meet legal obligations.
The app is a business tool and is not directed at children under 13 (or the age of digital consent in your country, if higher). We do not knowingly collect data from children.
If you are in the EU/EEA, UK or another jurisdiction with data-protection law, you have the right to access, correct, export or delete personal data held about you, to object to processing and to complain to a supervisory authority (in Estonia, the Andmekaitse Inspektsioon). Email us and we will help, including with requests to Adapty about subscription records.
Any change to this policy will be posted on this page with an updated effective date. Material changes will be announced in the app.
