The Invoice Maker
Privacy Policy
Effective 21 August 2026
This policy explains how Dynamic Falcon Lda (“we”, “us”) processes personal data in The Invoice Maker iOS application (“the App”), on its website, and when providing support.
1. Information stored on your device
The App lets you create and manage:
- business names, tax identifiers, contact details, and addresses;
- customer names, tax identifiers, contact details, and addresses;
- invoices, estimates, line items, prices, taxes, discounts, and payment status;
- products and services used in your documents.
This information is stored in the App’s local database on your device. We do not operate an account system or server that receives a copy of it. You are responsible for having a lawful basis to use information about your customers.
2. Analytics and diagnostics
The App uses Amplitude and Google Firebase services. They may process:
- sessions, screens viewed, feature use, and interface interactions;
- subscription product identifiers and purchase-flow events;
- app version, iOS version, device model, language, country or coarse location, carrier, IP address, and device or installation identifiers;
- crash reports, performance information, and related app or device state.
We use this information to understand App usage, diagnose errors, maintain security, measure performance, and improve the App. We do not intentionally include invoice, estimate, customer, or business-profile content in our custom analytics events.
We do not sell personal data or use it for cross-context behavioural advertising.
3. Purchases, PDFs, and sharing
Apple processes App Store purchases and subscriptions. We do not receive your full payment-card details. The App receives transaction and entitlement information required to provide paid features.
The App generates PDFs on your device. A document leaves the App only when you choose to print or share it. The destination you select processes the document under its own privacy terms.
4. Website and support
When you visit our website, the hosting provider may process standard request data such as IP address, browser and device information, requested URL, and timestamps. If you email us, we process your email address, message, attachments, and correspondence to respond to your request.
5. Service providers and disclosures
- Amplitude
- Product analytics and interaction measurement.
- Google Firebase
- Analytics, crash reporting, performance monitoring, sessions, and website hosting.
- Apple
- App distribution, subscriptions, purchases, printing, and user-directed sharing.
We may also disclose information when required by law, to protect rights or safety, or as part of a corporate transaction subject to appropriate safeguards.
6. Legal bases
Where the GDPR or similar law applies, we process personal data when necessary:
- to provide the App, purchases, or support you request;
- for our legitimate interests in security, diagnostics, performance measurement, and product improvement, where those interests are not overridden by your rights;
- with consent, where consent is required by law; or
- to comply with a legal obligation.
7. Retention and international transfers
Information stored in the App remains on your device until you delete it in the App or remove the App. Support correspondence is retained only as long as reasonably needed for support, security, or legal purposes.
Analytics and diagnostic data is retained according to our Amplitude and Firebase project settings and only as long as reasonably necessary for the purposes above. Aggregated or de-identified statistics may be retained longer.
Our providers may process data outside Portugal or the European Economic Area, including in the United States. Where required, transfers use appropriate contractual or other legal safeguards.
8. Your rights and deletion
Depending on applicable law, you may request access, correction, deletion, restriction, or portability of your personal data; object to certain processing; withdraw consent; or complain to a data protection authority.
You can delete business data in the App. Removing the App also removes its local data from the device, subject to device backups and copies you previously exported or shared. Deleting local data does not automatically delete analytics or diagnostic data already sent to a provider.
To exercise a privacy right, email us. We may request information needed to verify the request or locate a pseudonymous device record.
9. Children, security, and updates
The App is intended for business use and is not directed to children under 16. We use reasonable technical and organisational safeguards, but no system can be guaranteed completely secure.
We may update this policy when the App, our providers, or legal requirements change. The effective date above will identify the latest version.
