Terms of Use
1. Scope and Acceptance
1.1 These Terms of Use ("Terms") govern access to and use of the Link6 software-as-a-service platform, including its web application, mobile application, APIs, AI-assisted features, and related services (collectively, the "Service"), operated by Link6 GmbH, Hofstrasse 43, 6300 Zug, Switzerland ("Link6", "we").
1.2 By creating an account, accepting an invitation to an organization, or using the Service, you ("Customer", "you") accept these Terms. If you accept on behalf of a company or other legal entity, you represent that you are authorized to bind that entity, and "you" refers to that entity.
1.3 The Service is intended exclusively for business use by professional users. It is not directed at consumers.
2. The Service; Modifications
2.1 Link6 provides a project-tracking platform with AI-assisted features. The functional scope is as made available at the time of use; feature descriptions on marketing pages are non-binding unless expressly incorporated into a written agreement.
2.2 We may modify, extend, or discontinue features of the Service at any time, provided the core functionality contracted for is not materially diminished during a paid subscription period.
2.3 Trial plans are provided free of charge, "as is", without any availability commitment, and may be limited, suspended, or terminated at any time.
3. Accounts and Organizations
3.1 You must provide accurate registration information and keep credentials confidential. You are responsible for all activity under your account, except to the extent caused by our breach of these Terms.
3.2 Organization administrators control membership, roles, permissions, and data within their organization. Link6 acts on the instructions embodied in that configuration and is not responsible for access decisions made by the Customer's administrators.
3.3 You must notify us without undue delay of any suspected unauthorized use of your account.
4. Acceptable Use
4.1 You may not: (a) use the Service in violation of applicable law; (b) infringe third-party rights; (c) upload malicious code or attempt to probe, scan, or breach security or authentication measures; (d) access the Service to build a competing product; (e) resell or sublicense the Service except as expressly agreed; (f) use the Service to store or process data for which you lack the necessary rights or legal basis; (g) attempt to manipulate, jailbreak, or misuse AI features to produce unlawful output or to circumvent access controls; (h) upload, store, generate, or distribute pornographic or sexually explicit material, or any content involving sexual exploitation — content of this nature is prohibited regardless of its legality. For the avoidance of doubt, lit. (h) does not prohibit the professional documentation of workplace matters (e.g. HR or legal case tracking) that reference such subject matter without reproducing explicit material.
4.2 We may suspend access immediately where reasonably necessary to protect the Service, other customers, or third parties, and will inform you without undue delay.
4.3 No proactive monitoring. Link6 does not proactively monitor or scan Customer Data for content violations, except where and to the extent required by applicable law or a binding order of a competent authority. Enforcement of this Section 4 is otherwise notice-based: we act on reports, formal notices, and violations we incidentally become aware of (including through the operation of AI features, whose inputs are subject to the usage policies of the underlying model providers).
5. Customer Data
5.1 You retain all rights in data you or your users submit to the Service ("Customer Data"). You grant Link6 the non-exclusive right to process Customer Data solely to provide, secure, and improve the Service in accordance with these Terms and the Privacy Statement.
5.2 You are solely responsible for the legality, accuracy, and quality of Customer Data and for having all rights and consents required to submit it.
5.3 Data protection is governed by the Privacy Statement and, where applicable, a data processing agreement. Primary hosting is in Switzerland; the sub-processors and transfer safeguards are described in the Privacy Statement.
5.4 Upon termination, we will make Customer Data available for export for 30 days, after which it will be deleted in the ordinary course of our deletion and backup cycles, subject to statutory retention duties.
6. AI-Assisted Features — Specific Disclaimer
6.1 The Service includes features powered by machine-learning models (including third-party models). AI-generated output is probabilistic and may be inaccurate, incomplete, or inappropriate despite safeguards. AI output is provided for the Customer's review and requires human verification before being relied upon. Proposals generated by AI features do not take effect until approved through the Service's review mechanisms or the Customer's configuration.
6.2 To the fullest extent permitted by applicable law, Link6 assumes no liability for decisions taken, actions performed, or damage arising from reliance on AI-generated output without such verification.
7. Intellectual Property
7.1 The Service, its software, design, and documentation remain the exclusive property of Link6 and its licensors. You receive a non-exclusive, non-transferable right to use the Service for the subscribed term and scope.
7.2 Feedback you provide may be used by Link6 without restriction or compensation.
8. Fees, Payment and Prepaid Credits
8.1 Fees. Paid plans and credit packs are charged at the prices shown in the Service at the time of purchase. Prices are stated in Swiss francs (CHF) unless otherwise displayed; where a charge is settled in another currency, the amount and any applied exchange rate are shown before you confirm. Fees are exclusive of VAT and other applicable taxes. Subscription fees are governed by Sections 8.9 to 8.15; prepaid credits by Sections 8.2 to 8.8.
8.2 Business purchase. Credits are offered exclusively to Customers acting in a professional or commercial capacity (Section 1.3). By purchasing credits you confirm that you are acting on behalf of your organization and not as a consumer, and that you are authorized to commit your organization to the purchase.
8.3 Nature of credits. Prepaid credits are a prepayment for usage of the Service's AI-assisted features by your organization. Credits: (a) are credited to the purchasing organization, not to an individual user; (b) are consumed as the Service is used, at the rates displayed in the Service; (c) are non-transferable to any other organization or person; (d) cannot be exchanged, redeemed, or paid out for cash, and are not a means of payment, stored value, or e-money; (e) carry no interest.
8.4 Expiry. Credits expire on the date stated for the relevant pack at the time of purchase, shown in the Service before you confirm and in your balance thereafter. Credits are consumed oldest-expiring first. Unused credits lapse on expiry without refund or compensation.
8.5 No refund. Because credits are a prepayment for a service made available immediately upon purchase, purchases of credits are final and non-refundable, whether or not the credits are subsequently used. This does not affect: (a) any refund or remedy required by mandatory applicable law; (b) your right to a refund of the price paid where, through our fault, the purchased credits are not made available to your organization; (c) remedies expressly granted under Section 10 or an executed order form.
8.6 Acknowledgment. Before each purchase you must expressly acknowledge Sections 8.2 to 8.5 in the Service. We record that acknowledgment together with the version of these Terms, the acting user, the organization, and a server-side timestamp, and retain it as evidence of the transaction for the period required by law.
8.7 Plan changes, termination, discontinuation. Credits remain on the organization's balance if the organization's plan changes. If the organization's account is deleted at your request or terminated under Section 13.2 for your breach, any remaining credits lapse without refund. If we discontinue the Service entirely (Section 2.2), we will refund the unused portion of credits purchased within the preceding 12 months on a pro-rata basis.
8.8 Chargebacks and disputes. If a payment for credits is reversed, charged back, or disputed after credits have been granted, we may remove the corresponding credits (including any already-consumed portion, which may result in a negative balance to be settled) and suspend AI-assisted features for the organization until the balance is settled. If a subscription payment is reversed, charged back, or disputed, we may treat the affected period as unpaid and apply Section 8.12.
Subscriptions
8.9 Plans and billing basis. Paid plans ("Team", "Business") are offered as monthly subscriptions billed per active member of your organization. A subscription may only be started, changed, or cancelled by the organization's owner (Section 3.2). The plan features are those displayed in the Service at the time of subscription. Subscriptions are offered exclusively to Customers acting in a professional or commercial capacity (Section 1.3); by subscribing you confirm that you are acting on behalf of your organization and are authorized to commit it to recurring charges.
8.10 Active members. For each billing period the fee equals the per-member price of your plan multiplied by the number of active members on the day the charge is made. "Active members" are all user accounts belonging to your organization on that day whose access is not suspended and whose account is not scheduled for deletion. Pending invitations are not counted. The minimum is one member. Members added during a period are first charged in the next period; members removed during a period are still counted if the removal occurs after the charge. The current count and the resulting estimate are shown in the Service.
8.11 Payment authorization and renewal. When you subscribe, the fee for the first billing period is charged immediately and you authorize us, through our payment service provider, to charge your payment method automatically at the start of each subsequent billing period for the amount determined under Section 8.10. Billing periods are one month, starting on the day of the first payment. The subscription renews automatically for successive periods until cancelled under Section 8.13. The per-member price is the price displayed in the Service when you subscribe. We may change per-member prices with at least 30 days' prior notice to the organization owner; the new price applies from the first billing period starting after the notice period.
8.12 Failed payments. If a periodic charge fails, we notify the organization owner and retry the charge; we make up to three attempts over a period of approximately ten days. The organization retains full access during this period. If the final attempt fails, the subscription ends and the organization is placed in the read-only state described in Section 8.14. Amounts for periods in which the Service was available remain owed.
8.13 Cancellation. The organization owner may cancel the subscription at any time in the Service. Cancellation takes effect at the end of the billing period already paid for; the Service remains fully available until then and no further charges are made. A scheduled cancellation may be withdrawn in the Service before it takes effect. Fees for the current or any past billing period are not refunded, in whole or pro rata, on cancellation. This does not affect any refund or remedy required by mandatory applicable law or expressly granted under Section 10.
8.14 End of subscription; read-only state. When a subscription ends (Sections 8.12, 8.13, or termination under Section 13), the organization's workspace is placed in a read-only state: members can view and export their data but cannot create or change content, and paid-plan features are no longer available. Customer Data is retained in accordance with Section 5 and may be deleted under Section 13. The organization owner may start a new subscription at any time, upon which full access resumes. Prepaid credits are unaffected by the end of a subscription (Section 8.7).
8.15 Acknowledgment. Before starting a subscription the organization owner must expressly acknowledge Sections 8.9 to 8.14 in the Service. We record that acknowledgment together with the version of these Terms, the acting user, the organization, the plan, the member count and price at that time, and a server-side timestamp, and retain it as evidence for the period required by law.
9. Confidentiality
Each party will protect the other party's non-public information with at least the care it applies to its own comparable information, and use it only to perform under these Terms. This clause survives termination for 3 years.
10. Warranties — Disclaimer
10.1 The Service is provided "as is" and "as available". To the fullest extent permitted by applicable law, Link6 disclaims all warranties and guarantees, whether express, implied, statutory, or otherwise, including warranties of merchantability, fitness for a particular purpose, non-infringement, availability, accuracy, and uninterrupted or error-free operation.
10.2 No advice or information obtained from Link6 or through the Service creates any warranty not expressly stated in these Terms.
10.3 Any service-level commitments are set out in a separate document; remedies under it are exclusive.
11. Limitation of Liability — MAXIMUM RESTRICTION
11.1 Exclusion. To the fullest extent permitted by applicable law, Link6, its officers, employees, agents, and licensors shall not be liable for: (a) indirect, incidental, consequential, special, or punitive damages; (b) loss of profits, revenue, goodwill, or anticipated savings; (c) loss, corruption, or unavailability of data (including AI-generated content); (d) business interruption; (e) damage arising from third-party services, networks, or force majeure; (f) damage arising from the Customer's breach of these Terms, misconfiguration, or failure to maintain its own backups of exported data — in each case regardless of the legal theory (contract, tort, or otherwise) and even if advised of the possibility of such damage.
11.2 Cap. To the extent liability cannot be excluded, Link6's aggregate liability arising out of or in connection with the Service in any twelve (12) month period shall not exceed the total fees actually paid by the Customer for the Service in the twelve (12) months preceding the first event giving rise to liability; for free trial use, the aggregate cap is CHF 100.
11.3 Mandatory carve-out (Swiss law). Nothing in these Terms excludes or limits liability for damage caused by unlawful intent (Absicht) or gross negligence (grobe Fahrlässigkeit) within the meaning of Art. 100 para. 1 of the Swiss Code of Obligations, for personal injury, or for any other liability that cannot be excluded or limited under mandatory applicable law.
11.4 Claims period. Claims must be asserted within twelve (12) months of the Customer becoming aware of the damage, unless a longer period is mandatory by law.
12. Indemnity
You will indemnify and hold Link6 harmless from third-party claims, damages, and reasonable costs (including legal fees) arising from Customer Data, your use of the Service in breach of these Terms, or your violation of applicable law.
13. Term, Suspension, Termination
13.1 These Terms apply from account creation until termination of all subscriptions and deletion of the account.
13.2 Either party may terminate for material breach not cured within 30 days of notice. We may terminate trial accounts at any time.
13.3 Sections 5.4, 7, 8.3 to 8.8, 8.12 to 8.14, 9, 10, 11, 12, 14, and 15 survive termination.
14. Changes to These Terms
14.1 Each published revision carries a version identifier. Acceptance is recorded per user with the version accepted and a server-side timestamp.
14.2 We may revise these Terms. For non-material changes, we will publish the revised version with reasonable notice; continued use after the effective date constitutes acceptance. For material changes (including changes to liability, data processing, or fees), we will notify you at least 30 days in advance and require express re-acceptance before continued use.
15. Final Provisions
15.1 Governing law: Swiss substantive law, excluding conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods (CISG).
15.2 Jurisdiction: exclusive place of jurisdiction is Zug, Switzerland, subject to mandatory statutory venues.
15.3 If any provision is held invalid, the remainder stays in force; the invalid provision is replaced by a valid one closest to its economic intent.
15.4 These Terms, the Privacy Statement, and any executed order form or DPA constitute the entire agreement regarding the Service. In case of conflict, an executed order form or DPA prevails over these Terms.
