Terms and conditions · PatternNest

for the use and purchase of the “PatternNest” software

§ 1 Scope and Provider

  1. These Terms and Conditions apply to the use of the “PatternNest” web application (free tier and full version) and to the purchase of licence keys for the full version.
  2. The software is provided by Cayan Oyman, Ramsener Straße 43, 78239 Rielasingen-Worblingen, Germany, [email protected] (the “Provider”).
  3. For the purposes of these Terms and Conditions, a consumer is any natural person who enters into a legal transaction for purposes that are predominantly outside their trade, business or self-employed professional activity (§ 13 of the German Civil Code, BGB).

§ 2 Conclusion of the Contract and Payment Processing

  1. For purchases labelled “Sold through Link” at checkout, payment is processed through Stripe Managed Payments. Sold through Link, LLC acts as the Merchant of Record for payment and tax processing. Cayan Oyman remains the software provider and your contact for delivery, usage rights and product support. The Link terms linked at checkout also apply to the payment transaction. For earlier Gumroad purchases, the corresponding purchase documents and activation methods remain applicable.

  2. These Terms and Conditions govern the relationship between the Customer and the Provider in relation to the grant of rights to use the software (§ 4) and the provision of the application.

  3. After payment is confirmed, we provide the licence on your personal confirmation page and send it to the email address supplied with your purchase. You can use licence recovery to request another licence email for an eligible Stripe purchase. For earlier Gumroad purchases, the existing redemption pages for the respective applications remain available.

§ 3 Description of the Service

  1. PatternNest is a browser-based application for calculating fabric requirements and creating cutting plans for sewing patterns: it arranges imported pattern pieces (SVG, DXF, supported vector PDFs) on a selectable fabric width, takes into account direction rules set by the Customer (free rotation, grainline, one-way/nap) and mirrored pieces (“1 pair”), calculates the required fabric length or checks an available fabric length, and exports the cutting plan (PDF, SVG, DXF). The Customer’s files are processed entirely locally on their device; they are not transferred to the Provider’s servers.
  2. The free tier includes arrangement, fabric requirement calculation and export for projects with up to 10 fabric pieces and may be used free of charge for an unlimited time. Copies count towards the limit; a mirrored pair counts as two pieces. The full version is required to calculate and export larger projects.
  3. Use requires a current browser with WebAssembly support. The supported browsers are described on the product page.
  4. The calculation results relate to the imported geometry and the options selected by the Customer (in particular fabric width, cutting spacing, direction rules and mirroring). The software neither adds nor removes seam allowances; internal pattern markings (e.g. notches, grainline arrows and labels) are not reproduced in the exported plan; cut-on-fold layouts and pattern matching are available with fold edges and matching references selected by the Customer. The Customer must check the cutting plan before cutting (in particular dimensions and direction requirements), in accordance with standard professional practice; the Customer is responsible for the suitability of the fabric and sewing pattern.

§ 4 Rights of Use (Licence)

  1. Upon full payment, the Customer receives a perpetual, non-exclusive right to use the full version of PatternNest, major version 1 (v1.x), for their own purposes, including commercial purposes.
  2. The licence key is tied to the email address provided at purchase and may be used on all devices that the Customer personally uses.
  3. The following are not permitted: sharing, reselling or publishing the licence key; bypassing the licence check or the free-tier limits.
  4. Results created with the software (cutting plans, fabric requirement calculations, exported files) belong to the Customer; the Provider has no rights in them. Third-party rights in imported sewing patterns remain unaffected.
  5. Updates within major version 1 are included in the purchase price. There is no entitlement to new major versions or new features.

§ 5 Right of Withdrawal and Refunds

Consumers have the statutory right of withdrawal as set out in the withdrawal instructions. Independently of this, the Provider offers a voluntary refund commitment: a full refund within 14 days of purchase, without giving a reason (details on the withdrawal and refund page).

§ 6 Warranty

  1. The statutory provisions on liability for defects in digital products apply (§§ 327 et seq. BGB).
  2. The Provider supplies updates necessary to maintain the software’s conformity with the contract during the relevant period (§ 327f BGB).
  3. The characteristics of the software are defined by the service description in § 3 together with the product page and documentation. In particular, there is no guarantee that every possible file can be imported (closed outer contours from SVG/DXF and suitable vector PDFs are supported), or that a particular arrangement result (e.g. a particular fabric length) will be achieved; unreadable files are rejected with a specific error message.

§ 7 Liability

  1. The Provider has unlimited liability for intent and gross negligence and for damage arising from injury to life, body or health.
  2. In cases of ordinary negligence, the Provider is liable only for a breach of essential contractual obligations (cardinal obligations); in this case, liability is limited to foreseeable damage typical of the contract.
  3. Liability under the German Product Liability Act remains unaffected.
  4. The Customer must check the cutting plan against the dimensions and direction requirements before cutting, in accordance with standard professional practice; once fabric has been cut, this cannot be undone.

§ 8 Availability

After loading, the application runs entirely locally and can also be used offline as an installable app (PWA). The Provider is not obliged to ensure uninterrupted website availability; website interruptions due to maintenance or faults do not affect local use of installed instances.

§ 9 Final Provisions

  1. The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law applies only insofar as it does not deprive them of the protection of mandatory provisions of the law of their country of habitual residence.
  2. If the Customer is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is the Provider’s place of business.
  3. If any provision of these Terms and Conditions is invalid, the validity of the remaining provisions is unaffected.
