Effective: May 2026 Provider: Qorvano° — Dustin Dondrup Email: info@qorvano.com Website: www.qorvano.com
1. Scope
These Terms of Use govern the use of the application “Lineon” in all variants (iOS, Android and the web app at https://lineon.qorvano.com/), provided by Qorvano° — Dustin Dondrup (hereinafter “Provider”).
By installing, opening or using the app you agree to these Terms of Use.
2. Description of Services
Lineon turns a photo into a printable build guide for a string-art piece. The guide ships as a PDF with cover, materials list, 1:1 nail-layout diagram and a wrap-by-wrap table.
The variant determines the pricing model:
- Native (iOS, Android): one-time PDF export or lifetime unlock via in-app purchase.
- Web (
lineon.qorvano.com): pay-per-original-image via PayPal, with a 72-hour re-export window (max. 5 exports per paid image).
3. Pricing
3.1 Native: in-app purchases
Through Apple IAP or Google Play Billing the app offers two products:
- Single PDF export (consumable): unlocks one PDF download.
- Lifetime unlock (non-consumable): unlimited PDF exports for the lifetime of the app store. Restorable on reinstall via “Restore purchases”.
Current prices are shown in the respective app store. Transactions are processed exclusively by Apple or Google. The store operator’s purchase terms apply.
3.2 Web: pay-per-image via PayPal
On the web variant you pay per original image. After a successful payment you may re-export the PDF for that image up to five times within 72 hours — useful if you tweak the configuration or need a second print.
The re-export window is bound to the content of the original image, not to an account or a cookie. Within the 72 hours you can experiment with different crops and configurations — as long as you re-upload the same original image, the payment is recognised.
Lifetime is not offered on web. We cannot guarantee long-term availability of the web variant — for ongoing use, the native app with lifetime unlock is the right choice.
3.3 Right of withdrawal (web)
When the PDF export starts, the service is fully delivered. By clicking “Pay”, you expressly consent to the contract being executed before the withdrawal period ends — your right of withdrawal under § 356 (4) BGB / equivalent EU rules is thereby waived. For legitimate complaints (e.g. a technical fault preventing export) we refund the amount within 7 business days via PayPal. Write to info@qorvano.com with the PayPal order ID.
4. Intellectual Property
All rights to Lineon — including design, source code, algorithms, graphics and text — belong to the Provider. The app may not be copied, decompiled, modified or redistributed.
Generated build guides (PDF output) and the finished string-art pieces you make from them are yours. You may use them privately and commercially, including selling the finished works.
5. Disclaimer
5.1 Calculation results and print quality
The app is a tool for computing a string-art build guide. The Provider makes no warranty regarding the suitability of the result for a specific photo, board size or material. The look of the finished piece depends substantially on photo choice, board size, thread material and the craft of execution.
5.2 Availability
The Provider strives to keep the app available without interruption. No service-level agreement is given for the web variant — maintenance windows, temporary outages or a permanent shutdown of the web variant are possible. Already-paid images remain accessible via re-export within the 72-hour window; after that window the entitlement lapses.
5.3 Limitation of Liability
The Provider’s liability is limited — to the extent permitted by law — to cases of intent and gross negligence. Maximum total liability is capped at the amount you paid for the relevant variant.
6. Your Obligations
You agree to use Lineon only with images you have the rights to or that are in the public domain. The Provider assumes no liability for copyright infringements caused by images you upload.
7. Changes to Terms of Use
The Provider reserves the right to modify these Terms of Use. The current version is always available at www.qorvano.com/en/lineon/terms. Material changes are notified to native users in the app and to web users on the next visit.
8. Governing Law and Jurisdiction
The laws of the Federal Republic of Germany apply, excluding the UN Convention on the International Sale of Goods. The place of jurisdiction, to the extent permitted by law, is the Provider’s registered office.
