Sixtyfold Licensing and Commercial Terms
Version:
2026-08-17
How licensing works
Qualifying noncommercial use is free under PolyForm Noncommercial 1.0.0. Commercial development, CI, testing, private staging, review builds, and proofs of concept are also free. Buy a licence before Production Use or Commercial Redistribution. The purchase is perpetual for the major version bought and includes every update in that major version; later major versions are optional. Each eligible direct purchase has a 30-day money-back guarantee. Self-serve purchases are sold through Link as merchant of record.
Sixtyfold Components v1 is the major version on sale today. Its stable release shipped on 16 August 2026.
| Path | Scope |
|---|---|
| Noncommercial | Qualifying use under PolyForm |
| Commercial development | Non-production development and testing |
| Solo — Components v1 | One sole trader or freelancer; unlimited products personally owned and operated |
| Company — Components v1 | One legal entity with up to 50 employees; unlimited developers and standard applications |
| Enterprise & OEM — Components v1 | One legal entity of any size; unlimited standard applications and up to 10 redistributed products |
Sixtyfold is source-available, not OSI-approved open source. PolyForm remains an independent grant. The numbered terms below control free commercial development and paid commercial licences.
1. Parties and definitions
The licensor is Different Planet - Unipessoal Lda., registered at Rua Fialho de Almeida nº14, 2º Esq - Office FG20, 1070-129 Avenidas Novas, Lisbon - Portugal, registration/NIPC 516082000, EU VAT number PT516082000 (Licensor).
A Developer is a person or entity using the free rights in section 2. A Licensee is the person or legal entity named in checkout or a signed order. Using the free grant or completing an order accepts these terms; anyone acting for an organisation confirms authority to bind it.
Software means the Sixtyfold Components packages published as part of the purchased component-suite major version. Sixtyfold Charts is included today; additional Sixtyfold components published within that same major version are included when released. Purchased Major Version means the suite major version named on the checkout page, in the order confirmation, and on the receipt, including all its minor, patch, and maintenance updates. The Purchased Major Version on sale today is Sixtyfold Components v1, covering the whole 1.x series. A purchase made before that major version reaches its first stable release also includes its remaining prereleases and its complete stable series.
Production Use means a live application or workflow used for real business operations or ordinary employee, customer, or public use. It excludes local development, private CI, automated tests, access-controlled staging, temporary review or UAT builds, and non-operational proofs of concept.
Commercial Redistribution means supplying the Software for another person or entity to install, host, develop against, extract, or reuse, including on-premises delivery, OEM installation, SDKs, builders, white-label components, and customer developer rights. It excludes an inseparable browser bundle in a Licensee-hosted application when end users cannot use the Software separately. Qualifying noncommercial redistribution remains governed by PolyForm.
2. Free commercial development
Licensor grants Developer a nonexclusive, nontransferable, nonsublicensable licence to install, run, reproduce, modify, benchmark, and use the Software for non-production commercial development. This includes private CI and build systems, tests, staging, QA, UAT, internal proofs of concept, and reasonable backups. No payment card, account, registration, licence key, or time limit is required.
Employees, contractors, and invited client reviewers may participate only in the same controlled project. The grant does not permit Production Use, Commercial Redistribution, general end-user availability, a live commercial service, or exposing Sixtyfold as a separately usable component. It includes public documentation but no promised support, fix, cadence, response time, warranty, or SLA. Required notices must remain intact.
3. Plans and eligibility
| Plan | Eligible Licensee | Paid scope |
|---|---|---|
| Solo | One natural person working directly as a sole trader or freelancer, not through a company | Unlimited standard applications personally owned and operated by that person |
| Company | One legal entity with no more than 50 employees when it buys the major version | Unlimited developers and standard applications owned or controlled by that entity |
| Enterprise & OEM | One legal entity of any size | Unlimited developers and standard applications, plus up to 10 Redistributed Products |
A standard application does not expose the Software as a separately usable component. A Redistributed Product is one separately marketed application, product line, SDK, builder, or white-label product; its deployments, editions, and versions do not count separately.
Solo cannot be shared. A limited company, employer, client, partnership, or other entity that owns or operates the application needs Company or Enterprise & OEM, even when one person does all development. Company and Enterprise & OEM cover employees and contractors acting only for the named entity, not parents, subsidiaries, affiliates, clients, or other legal entities.
Company eligibility is measured at purchase. Later growth beyond 50 employees never revokes rights already bought, but a new major version or expanded scope requires Enterprise & OEM while the entity remains over the threshold.
Enterprise & OEM includes up to 10 Redistributed Products. More products, multiple legal entities, affiliate rights, or negotiated procurement, support, or SLA terms require a custom signed order.
4. Perpetual paid licence
After cleared payment, Licensor grants Licensee a nonexclusive, nontransferable, nonsublicensable, perpetual licence within the purchased scope to use, reproduce, modify, build with, deploy, redeploy, and maintain the Purchased Major Version; create new standard applications with it at any time; serve those applications to end users; and keep reasonable backup and build copies. Required notices must remain intact.
The grant is not metered by developer seat, domain, deployment, standard application, application user, or data volume. A later major version, support change, or price change does not end it or disable the Software.
Enterprise & OEM may distribute the Software inseparably in up to 10 Redistributed Products. Customers receive only the rights needed to use those products, not to extract or reuse Sixtyfold separately.
5. Restrictions
Unless Enterprise & OEM or a custom order expressly permits it, Licensee must not:
- commercially redistribute or expose the Software as a standalone or competing library;
- sublicense, sell, rent, transfer, assign, or share the licence;
- use it for an unnamed affiliate, client, or other legal entity;
- provide customer developer rights or customer-controlled installations;
- offer Sixtyfold as a component in a builder, SDK, or developer tool; or
- remove required proprietary or third-party notices.
AI tools, generators, agents, translators, obfuscators, and refactoring tools do not expand the licence. Independently created software is not covered merely because it implements similar ideas, interfaces, behaviour, or functionality.
6. Updates and support
The purchase includes every update in the Purchased Major Version. There is no customer-specific update clock, maintenance renewal, automatic renewal, back payment, licence account, runtime activation, or phone-home requirement, and no release cadence is promised.
Standard email support at support@sixtyfold.dev covers installation, documented configuration, public API questions, defect triage, and licence administration—not consulting, customer-code debugging, custom work, security review, on-call response, guaranteed timing, or an SLA. Solo support is for the named Licensee; Company and direct Enterprise & OEM support up to two technical contacts. Support applies while that major version is current. After a successor becomes current, the preceding version receives critical security and defect fixes for 12 months.
7. Orders, later major versions, and tax
Current offers are published on the Pricing page. Checkout or a signed order identifies the plan, purchased major version, price, currency, and tax accepted for that order. A later major version is a separate optional product offered at its then-current price. The version already bought remains licensed forever, with no obligation to buy or migrate.
Checkout, the order confirmation, and the receipt identify the major version sold. If an upcoming major version is sold before its stable release, that purchase may also be used in production with the current major version until the successor is available. Prices may change only for future purchases.
Checkout or a signed order shows the currency, tax, and final total before payment. In self-serve checkout, Link is the merchant of record and handles payment processing, indirect tax, receipts, transaction support, and transaction refunds. Licensor provides the Software, licence, and support described here.
8. Refunds and payment reversals
Each direct purchase of a new Purchased Major Version may be cancelled for a full refund by writing to sales@sixtyfold.dev within 30 calendar days. The guarantee excludes custom orders, duplicate purchases of the same major version, replacements, and a major version the same person or entity previously refunded.
For self-serve purchases, a buyer may also contact Link. Stripe/Link may issue a refund in its discretion within 60 days and may refund if Licensor does not answer a transaction-support escalation within 48 hours. That authority does not extend Licensor's 30-day guarantee; checkout terms and mandatory law may provide separate rights.
The paid commercial licence follows three payment outcomes:
- It ends only when: a completed full refund, whether issued by Licensor, Stripe, or Link, or a final lost chargeback or other final payment reversal removes the full original payment.
- It does not end when: a refund is pending, a dispute remains open, or any part of the original payment remains in place.
- It is reinstated when: a failed or cancelled refund, later win, withdrawal, or similar decision restores the full payment and that payment event was the sole reason for revocation. This does not reverse an agreed surrender or breach termination.
After a final full reversal, Licensee must stop Production Use and remove that major version from production. Other purchased major versions, the free commercial-development grant, and independent PolyForm rights are unaffected.
Delivery begins electronically after successful checkout. By completing checkout, the buyer requests immediate access and acknowledges that delivery may affect a statutory withdrawal right. This guarantee does not limit mandatory rights.
9. Termination and ownership
The paid grant may end only through a completed full refund, final reversal of the full payment, agreed surrender, or termination for an uncured material breach after any notice and cure required by law. A new major version or support transition is not termination.
These terms license the Software; they do not sell or transfer title. Licensor and contributors retain their Software rights, while Developer and Licensee retain independently developed application code and data. There is no mandatory activation or phone-home. On reasonable written notice, Licensee must provide information reasonably needed to confirm plan scope.
10. Warranty and liability
To the maximum extent permitted by law, the Software is provided as is and as available, without warranty. Developer and Licensee are responsible for evaluation, testing, backups, and safe integration.
To the maximum extent permitted by law, Licensor is not liable for any direct, indirect, incidental, special, consequential, exemplary, or punitive loss or damage arising from these terms or the Software, under any legal theory, even if advised that it was possible. Nothing excludes liability or mandatory rights that cannot lawfully be excluded or limited.
11. Law and contact
Portuguese law governs these terms and related non-contractual obligations. To the extent permitted by mandatory law, courts with territorial jurisdiction over Lisbon, Portugal have exclusive jurisdiction. Non-waivable rights, supervisory-authority processes, and urgent relief in another competent court remain available.
