Terms of Use

Carol, knitting app for iPhone

Last updated: 19 July 2026

1. Scope

These terms of use apply to the use of the iOS application "Carol" (the "app"), developed and published by Ferdinand Drobik under the name Nordic App Studio (the "developer").

By downloading, installing, or using the app, you agree to these terms. These terms apply in addition to the Apple App Store's general terms and conditions.

2. Description of the app

Carol is a knitting app for iPhone. It adapts existing knitting patterns to your own gauge, a different yarn, and the measurements you want, and guides you as you knit.

Among other things, the app offers:

• conversion of patterns to your own gauge, with stitches and rows handled separately
• planners for top-down raglan, body and sleeves, socks and hats, short rows, and yarn requirements
• a guided pattern adjuster
• a knitting mode with a round counter, an undo history, and reminders
• projects, a swatch library, backup as a file, and text export

The app is available in German, Danish, and English. It runs entirely on the device and sends none of your entries or personal data over the network. It has no accounts and shows no ads.

3. Calculations and your own responsibility

Carol is a calculation and planning tool. The results are an aid, not a guarantee. They depend directly on the values you enter, in particular on your gauge.

For that reason:

• Always knit your own swatch before a larger project and measure it carefully.
• Check the suggested stitch and row counts, as well as the rounding and deviation shown, before you cast on.
• Yarn, needle size, knitting technique, and personal tension affect the result and are outside the app's control.

The developer gives no warranty that a piece knitted according to the app's suggestions will achieve a particular fit, size, or look.

4. Disclaimer of liability

As far as legally permitted, the developer is not liable for:

• results that do not match your expectations, such as a piece that turns out differently than planned
• material or time spent that arises from using the app
• loss of locally stored project data through device failure, software error, or accidental deletion
• loss of backups or exports that you have not kept separately
• incompatibilities with future iOS versions or hardware changes that may affect performance or stability

Mandatory statutory liability, for example for intent, gross negligence, or under product liability law, remains unaffected. Otherwise, use of the app is at your own risk.

5. Purchases, Carol Pro, and right of withdrawal

Carol is free to download. The free version includes one project and part of the calculators. An optional one-time purchase (Carol Pro) unlocks unlimited projects, all calculators and assistants, the knitting mode with reminders, the swatch library, and backup and export. The pattern shop contains free knitting patterns; individual patterns may in future be offered there as an in-app purchase. It is not a subscription; Carol Pro is a one-time purchase and does not renew automatically.

All purchases are handled exclusively through the Apple App Store. Apple is the contracting party for the purchase. Prices are shown to you before purchase in the App Store. The app itself receives no payment data.

Management, cancellation of purchase transactions, and refund requests run through your Apple ID account and the App Store, not through the developer. You can find information on this at Apple: Request a refund.

Right of withdrawal for digital content. As a consumer, you generally have a 14-day right of withdrawal for purchases made in the App Store. For digital content, the right of withdrawal expires once performance has begun with your express consent and you have confirmed that you thereby lose your right of withdrawal. Because in-app purchases are unlocked immediately after purchase, this exception usually applies. The withdrawal and refund procedure follows the Apple App Store's terms and is handled through Apple.

6. Intellectual property

All content of the app, in particular source code, calculation logic, layout and design, icons and graphics, texts, and the knitting patterns shipped with or offered in the app, is the intellectual property of the developer and protected by copyright. No part of the app may be reproduced, distributed, decompiled, or used commercially without prior written permission, unless such a restriction is excluded by mandatory law.

The projects you create, your swatches, and your own patterns remain your property. The app claims no rights to this content.

7. Licence to use

The app is licensed to you, not sold. You receive a non-exclusive, non-transferable licence to use the app for private purposes on Apple devices that you own or control, in accordance with the Apple Standard End User License Agreement (EULA).

8. Availability and updates

The developer endeavours to keep the app functional and up to date. However, there is no guarantee that the app will be available at all times, free of errors, or compatible with all future iOS versions and device configurations. Updates may change, add, or remove features.

9. Applicable law

These terms of use are governed by the law of the Kingdom of Denmark, unless mandatory consumer protection law of your country of residence provides otherwise.

10. Changes to the terms

The developer reserves the right to update these terms of use. The current version is available within the app and in the App Store. Continued use of the app after changes constitutes acceptance of the updated version.
