Terms of Use

Effective date: October 27, 2026

1. Agreement

These Terms of Use apply to Paperplane, an iPhone app for creating invoices, estimates and receipts, developed by Sergei Stasenko (“we”). By downloading or using Paperplane, you agree to them.

2. License

Paperplane is licensed to you under Apple's Licensed Application End User License Agreement (EULA). These terms add to the EULA; if they conflict, the EULA prevails.

3. Your documents are your responsibility

Paperplane is a tool for preparing and sending documents. You're responsible for what your documents say and how you use them: prices, quantities, taxes, discounts, numbering, payment terms and the details your country requires on an invoice or estimate. The app calculates totals and taxes from the rates you enter; check them before you send. Paperplane doesn't give tax, legal or accounting advice.

4. E-invoicing (XRechnung)

For invoices in euros, Paperplane can export an XRechnung file (EN 16931, CII syntax), and it can open incoming XRechnung and ZUGFeRD invoices. Before export, the app checks the file against the rules it implements, but it can't guarantee that a recipient, a portal or a tax authority will accept the file, or that the file meets your obligations. Whether and how you must issue e-invoices is for you and your tax adviser to decide.

5. Free use and Pro

Paperplane is free to download. Creating and editing documents, clients, items, expenses, time entries and reports, and syncing them with iCloud, cost nothing. Your first document can be sent, printed and exported as often as you like to the same client. Sending, printing and exporting further documents, payment receipts and bulk exports need Paperplane Pro.

  • Pro is an auto-renewable subscription: monthly ($9.99 USD) or annual ($59.99 USD). The price in your country is shown in the App Store and in the app before you buy and may include local taxes. There is no free trial.
  • Payment is charged to your Apple Account when you confirm the purchase.
  • The subscription renews automatically unless you cancel it at least 24 hours before the end of the current period. The renewal is charged within 24 hours before the period ends.
  • You can manage or cancel the subscription in your Apple Account settings (iOS Settings › your name › Subscriptions). After you cancel, Pro stays active until the end of the period you paid for.
  • Purchases are processed by Apple, and refunds are handled by Apple under its policies.
  • To use Pro on another device signed in to the same Apple Account, tap “Restore purchases” in Settings or on the upgrade screen.

We may change what Pro includes or what it costs. A price change for an existing subscription follows the App Store rules, which ask for your consent when required.

6. Your content

Everything you create in Paperplane belongs to you. We don't access it and claim no rights to it. You confirm that you may use the information, logos and photos you add, including your clients' details.

7. iCloud and backups

Sync and storage in iCloud are provided by Apple under the iCloud Terms and Conditions. We aren't responsible for data lost through iCloud outages, account problems or deletion. If you need an independent copy, export your documents and data regularly (Settings › Import & Export).

8. Third-party services

Paperplane relies on Apple (App Store, iCloud), RevenueCat (subscription status) and TelemetryDeck (anonymous usage statistics). Their own terms apply to their services. Our Privacy Policy describes what they receive.

9. Acceptable use

Don't use Paperplane to create fraudulent or misleading documents, to break the law or to infringe the rights of others.

10. Changes to the app and these terms

We may update, change or discontinue features. We'll post updated terms on this page with a new effective date; if you keep using the app after that, you accept them.

11. Disclaimer of warranties

PAPERPLANE IS PROVIDED “AS IS” AND “AS AVAILABLE”, WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. WE DON'T WARRANT THAT THE APP WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT ITS CALCULATIONS, TAX AMOUNTS OR E-INVOICE FILES WILL MEET YOUR LEGAL REQUIREMENTS.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, Sergei Stasenko SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, PROFITS, REVENUE OR GOODWILL, ARISING FROM YOUR USE OF PAPERPLANE OR FROM DOCUMENTS CREATED WITH IT. OUR TOTAL LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE APP IN THE TWELVE MONTHS BEFORE THE CLAIM.

13. Governing law

These terms are governed by the laws of the State of California, United States, without regard to its conflict-of-law rules. If you use Paperplane as a consumer, you also keep the protection of the mandatory laws of the country where you live, and nothing in these terms limits those rights.
