Terms of Service & End-User License Agreement

You must be old enough, and have the legal capacity, required by the mandatory law of your country of habitual residence to use the Service and to enter this Agreement. Creating a Free account is not a paid contract. A Maker or Commercial subscription may be purchased only by a person who has capacity under that law to conclude the paid contract, or by a holder of parental responsibility acting on their behalf. By creating an account or purchasing a subscription, you represent that you meet the applicable requirement.

You also agree to be bound by this document, our Privacy Policy, our Acceptable Use Policy, and our Refund & Cancellation Policy.

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us immediately at info@primalog.pl if you suspect unauthorised access.

Paid subscriptions are purchased through Paddle. Access keys are internal support grants and are not a public purchase path.

When you purchase a paid subscription, that transaction is conducted by the applicable Paddle contracting entity identified in Paddle's current Buyer Terms (“Paddle”), acting as the Merchant of Record. Paddle is the authorised reseller for your purchase: it issues your receipt or invoice, and it determines, collects, and remits any applicable VAT, sales tax, or similar consumption tax. Your purchase is governed by Paddle's Buyer Terms and Refund Policy.

Separately from that transaction, this document is the direct contract between you and Primalog, governing your right to access the Software and to use the Output it generates. Continued payment to Paddle for an active subscription is a condition of your continued rights under the tier it funds — see Section 4.2 for what happens to previously generated Output if a subscription lapses.

Primalog grants you a limited, non-exclusive, non-transferable, revocable license to access the Software and use Output generated during an active subscription, according to your tier as summarised above.

4.1 Maker — Personal Use License

Under the Maker tier, you may:

• Generate, download, and print Output for your own private, household use.
• Share photographs or videos of items printed from Maker Output on social media and 3D-printing community platforms for non-commercial purposes.

Under the Maker tier, you may NOT:

• Sell, lease, barter, or otherwise distribute physical items printed from Maker Output.
• Use Maker Output for any commercial purpose, paid client work, or professional service.
• Sub-license, sell, or transfer this license or any rights under it.

4.2 Commercial — Production License and vested rights

Under the Commercial tier, you have all Maker rights, plus the non-exclusive right to:

• Manufacture physical objects printed from the Output and sell those objects to third parties, including through commercial e-commerce platforms.
• Use Studio-generated designs in commercial projects, client work, and paid services.

Survival of commercial rights. Physical objects manufactured from Output that was generated and exported while a Commercial subscription was actively maintained may continue to be sold indefinitely, including after that subscription is later cancelled or expires. This does not apply to Output generated after cancellation or expiry: any Output generated after your Commercial subscription lapses is governed strictly by the tier active on your account at the time of that later export.

We keep a server-side record of the tier active at the moment each file is generated so that this right can be verified.

4.3 Restrictions applicable to every tier

You may not:

• Reverse-engineer, decompile, or disassemble the Software.
• Remove or obscure any proprietary notices or labels.
• Use the Software to create content that infringes third-party intellectual property.
• Circumvent any access control, entitlement check, or tier restriction.

Under every tier — Free, Maker, or Commercial — you may NOT sell, sublicense, share, publish, or distribute the Output in any digital format (including STL, 3MF, G-code, or a derived 3D mesh), whether for a fee or free of charge, including by uploading it to a model-sharing repository, digital marketplace, or community platform.

This restriction is contractual: it applies regardless of whether the Output itself qualifies for copyright protection, because it is a condition of the license granted under Section 4, not a claim over authorship of the file. A mesh derived from Output by editing, scaling, or combining it with other geometry is subject to the same restriction.

A breach of this section is a material breach of this Agreement. It may result in immediate suspension or termination of your account and liability for damages under applicable law. Any refund consequence remains subject to Paddle's decision and mandatory consumer law. See Section 2 of our Acceptable Use Policy for how we enforce this — we act on reports and legal demands, and we do not represent that redistribution is detected automatically.

Primalog retains all right, title, and interest in and to the Software, including its parametric algorithms, geometry engine, code, and user interface. This document conveys no ownership rights in the Software.

You retain ownership of the technical dimensions and parameter configurations you author. Your rights to use, print, or commercialise the resulting Output are governed exclusively by Sections 4 and 5 above, according to your tier.

By saving a project to Studio cloud storage, you grant us a limited, non-exclusive licence to store and display that project solely for the purpose of operating the Service for you.

Primalog designs and validates the Software to deliver digital Output files using standard 3D mesh specifications and to conform to the dimensions and format you selected in the interface. If an Output file is technically defective or does not match those selections, contact us so that we can investigate and provide the remedies required by applicable law.

We do NOT warrant or guarantee physical printing outcomes. The physical result depends entirely on variables you control: 3D printer calibration, slicer settings, nozzle condition, material and filament shrinkage, and ambient conditions. Wasted filament, machine wear, a failed print bed, or a dimensionally inaccurate physical print does not by itself constitute a defect or non-conformity of the digital Software or Output.

Mandatory withdrawal and cancellation rights depend on the country of purchase and whether you buy as a consumer. Paddle's current Refund Policy recognises a 14-day withdrawal period for eligible first subscription payments in the European Union, European Economic Area, Switzerland, and the United Kingdom, and describes different periods or remedies for several other countries.

Where the law and Paddle policy for your country allow a withdrawal right for digital content to cease when delivery begins, CubeOn Studio asks for the required express, informed consent and acknowledgement through a clear, unticked checkbox before the first paid Output export. The routing country comes from the billing-address snapshot attached to the completed Paddle transaction; it is not inferred from interface language, IP geolocation, or Primalog's Polish domicile. The confirmation is sent afterward on a durable medium (an email you can keep, with a copy of this document attached). If no valid waiver applies, your mandatory rights remain unaffected. The consent asked at first paid export concerns delivery of that digital Output; it does not, by itself, take away withdrawal or refund rights that mandatory law or Paddle's policy still grant for the subscription service.

In the European Union this includes the conditions in Article 16(m) of Directive 2011/83/EU and national implementing law (in Poland, Article 38(1)(13) of the Act on Consumer Rights). Other countries may classify CubeOn Studio, its subscription service, and generated Output differently; their mandatory rules take precedence over this document.

Cancellation and refund requests are handled by Paddle as Merchant of Record. See our Refund & Cancellation Policy for the available request channels and the current Paddle policy.

Paid subscriptions are billed on a recurring basis through Paddle (Section 3). Subscriptions may be cancelled at any time; cancellation takes effect at the end of the current billing period, and Section 4.2 governs what happens to Output already generated under a Commercial subscription. Paddle displays the total Charges, including applicable taxes, at checkout and in the transaction confirmation; taxes may be included in or added to the displayed base price according to the purchase location and applicable rules. We may change pricing for future billing periods with reasonable advance notice. Refunds and statutory withdrawal rights are described in our Refund & Cancellation Policy.

Business users (B2B). To the maximum extent permitted by law, Primalog's total aggregate liability arising out of or related to this Agreement is limited to the total amount you paid for the Software in the twelve (12) months preceding the event giving rise to the claim. Primalog is not liable for indirect, incidental, special, consequential, or punitive damages.

Consumers (B2C). Nothing in this Agreement limits or excludes Primalog's liability for death or personal injury caused by negligence, for fraud or gross negligence, or for any other liability that cannot be limited or excluded under the mandatory consumer-protection law of your country of habitual residence.

If a paid subscription is cancelled, expires, or downgrades to Free, existing Studio cloud projects are not deleted automatically. You can still view them. Creating, editing, or deleting Studio cloud projects requires a Maker or Commercial plan (or an equivalent paid grant). If you move from Commercial to Maker with more than 25 cloud projects, you may still edit or delete existing projects, but you cannot add new ones until you are at or below that cap. Paid file export (STL, 3MF, assembly PDF) follows the tier active at the time of export.

This license is effective until terminated. We may suspend or terminate your license and account immediately for a material breach of this Agreement, including a breach of Section 5. Upon termination you must stop using the Software; Sections 5, 6, 10, and 13 survive termination.

This Agreement is governed by the laws of Poland, without regard to its conflict-of-law principles. If you are a consumer, the mandatory statutory consumer-protection rights of your country of habitual residence remain unaffected and are not limited by this choice of law. Schedules A and B below add region-specific terms for United States and EU/UK residents respectively, and take precedence over the general terms above where they conflict, but only for the residents they name.

We may update this Agreement. Material changes will be communicated by email or an in-product notice at least 30 days in advance where they affect your existing rights. Continuing to use the Service after a change takes effect constitutes acceptance of the updated Agreement; where required by law, we will ask you to re-accept explicitly.

Questions about this Agreement: info@primalog.pl; telephone +48 572312500.

Mandatory consumer rights. If you use the Service as a consumer in the United States, applicable federal and state consumer-protection laws remain unaffected. Nothing in this Agreement requires a consumer dispute to be arbitrated under commercial arbitration rules or waives a non-waivable court, jury, representative-action, warranty, or remedy right granted by applicable law.

Mandatory digital content and service rights. The mandatory conformity, remedy, cancellation, and withdrawal rights provided by the law applicable in your EU or EEA Member State or in the United Kingdom remain unaffected. Section 7 describes the technical service commitment without replacing those statutory remedies.

Out-of-court dispute resolution. EU consumers may contact a competent consumer-protection authority, consumer ombudsman, or alternative dispute resolution entity available under the law of their country. The former European Commission Online Dispute Resolution platform was discontinued in 2025 and is not presented as an active complaint channel.
