Effective date: September 3, 2026
These terms govern your use of the Rapid Invoice app for iOS and Android (“the app”), published by Zintex OÜ, Ahtri tn 12, Tallinn 15551, Estonia (“we”). By installing or using the app you agree to them.
Rapid Invoice is a tool for creating invoices, estimates and receipts, keeping a list of clients and items, and tracking which invoices have been paid. It produces documents from the information you enter. It is not an accounting service, a tax adviser, or a payment processor, and it does not file anything with any authority on your behalf.
You are responsible for the content and legal validity of every document you create. Invoice numbering, tax rates, currency, required legal wording and retention periods differ by country and by type of business; it is up to you to make sure your invoices meet the rules that apply to you. The templates are a starting point, not legal or tax advice.
We grant you a personal, non-transferable licence to use the app on devices you own or control, subject to the App Store or Google Play terms under which you obtained it. You may not copy, modify, reverse engineer, resell or redistribute the app, or use it to build a competing product.
Some features are available only with a paid plan sold through the App Store or Google Play at the price shown in the app before you buy.
One-time purchases, where offered, are charged once and stay unlocked on the same store account. You can restore them on a new device with the “Restore purchases” button.
Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Where a free trial is offered, the subscription starts and is charged when the trial ends unless you cancel first. Payment is charged to your store account on confirmation of purchase and again at each renewal. Manage or cancel a subscription in Settings → Apple Account → Subscriptions on iOS or in Google Play → Payments & subscriptions on Android; uninstalling the app does not cancel it.
Refunds are handled by Apple or Google under their own policies; we are not able to issue them ourselves.
Everything you enter — business details, logo, clients, invoices — belongs to you and stays on your device. We have no access to it and keep no copy. That also means we cannot recover it if you delete the app, reset or lose your device, or if a backup fails. Please export or back up documents you need to keep.
Do not use the app to create fraudulent, misleading or unlawful documents, to impersonate another business, or to break any law. Do not attempt to disrupt the app or to circumvent its purchase mechanisms.
The app is provided “as is”, without warranties of any kind, express or implied. We do not guarantee that it will be error-free or available at all times, or that the documents it produces are correct or compliant for your situation. To the extent permitted by law, we are not liable for indirect or consequential loss, lost profits, lost data or tax penalties, and our total liability to you is limited to the amount you paid for the app in the twelve months before the claim.
You can stop using the app at any time by deleting it. We may suspend or end your access if you breach these terms.
We may update these terms; the effective date above will change and material changes will be announced in the app. Continued use after an update means you accept it.
These terms are governed by the laws of Estonia. Nothing in them limits the consumer rights you have under the mandatory law of the country where you live.
