Terms and Conditions

"Service" means the Decern platform, including the web application, dashboard, APIs, CLI tools (decern gate, decern init, decern adr sync), documentation, and all associated infrastructure operated by Decern.

"Customer Data" means any data, code diffs, ADR files, evidence records, signal data, configuration, or other content that you or your authorized users upload, submit, or transmit through the Service.

"ADR" (Architecture Decision Record) means a markdown file in the customer's repository that documents an architectural decision, including frontmatter metadata (status, enforcement, scope) and body sections (Context, Decision, Consequences).

"Gate" means the CI gate tool that evaluates pull request diffs against ADRs using the customer's BYO LLM, producing verdicts (pass, violation, unrelated, error) with confidence scores.

"Signal" means an architectural decision detected in a pull request that is not covered by any existing ADR (Case C verdict).

"Evidence Record" means the immutable, hash-chained, cryptographically signed record produced by each gate run, stored for audit and compliance purposes.

"Subscription" means the paid or free plan selected by the Customer, as described on the pricing page.

"Authorized User" means any individual granted access to the Service through the Customer's account.

"BYO LLM" (Bring Your Own LLM) means the configuration where the Customer provides their own API keys for a third-party large language model provider used by the gate for ADR evaluation.

By creating an account, accessing the Service, or using any part of the platform, you represent and warrant that you have the legal authority to enter into these Terms on behalf of yourself or the organization you represent.

If you are using the Service on behalf of a company, organization, or other legal entity, you represent that you have the authority to bind that entity to these Terms. In such case, "you" and "Customer" refer to that entity.

You must be at least 18 years of age to use the Service. By using the Service, you represent and warrant that you meet this requirement.

You must provide accurate, complete, and current information during registration and keep your account information up to date at all times.

You are solely responsible for maintaining the confidentiality of your account credentials, including passwords and CI tokens. You are responsible for all activities that occur under your account, whether or not authorized by you.

You must notify us immediately at opensource@decern.dev if you become aware of any unauthorized use of your account or any security breach.

Decern reserves the right to suspend or terminate any account that is reasonably believed has been compromised or is being used in violation of these Terms.

The Service is offered under multiple subscription tiers (Free and Enterprise), each with different features and usage limits as described on the pricing page.

Enterprise subscriptions are billed under a custom agreement. All fees are quoted in Euros (EUR) and are exclusive of applicable taxes, which will be added where required by law.

You authorize Decern to charge your designated payment method for all fees associated with your selected plan. Failure to pay may result in suspension or termination of your access to the Service.

Decern reserves the right to change pricing at any time. Price changes for existing subscriptions will take effect at the start of the next billing cycle, with at least 30 days' prior notice.

All fees are non-refundable except where required by applicable law.

The Free plan provides full access to the CI gate, signal detection, dashboard, and evidence chain for one workspace with up to three developers. It is offered at no charge.

Decern reserves the right to modify, limit, or discontinue the Free plan at any time without prior notice. Free plan users have no guaranteed service level.

Draft ADR generation from signals (cloud LLM feature) and PR creation from the dashboard are not available on the Free plan.

You may upgrade your subscription at any time through the Service. Upgrades take effect immediately.

When downgrading, features associated with higher-tier plans may become inaccessible. Decern is not responsible for any loss of access to features resulting from a downgrade.

If you exceed the usage limits of your current plan, Decern may restrict access to certain features until you upgrade or reduce your usage.

Subject to your compliance with these Terms and payment of applicable fees, Decern grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Service during the term of your subscription.

This license does not include the right to: (a) sublicense, resell, lease, or distribute the Service; (b) modify, reverse-engineer, decompile, or disassemble any part of the Service; (c) use the Service to build a competing product; (d) access the Service through automated means except through the official CLI and API; (e) remove or alter any proprietary notices on the Service.

Decern reserves all rights not expressly granted in these Terms.

You agree not to use the Service to: (a) violate any applicable law or third-party rights; (b) upload malicious code or harmful content; (c) interfere with the integrity or performance of the Service; (d) attempt to gain unauthorized access to the Service or related systems; (e) store or process sensitive personal data unless explicitly agreed.

Decern reserves the right to suspend or terminate access to any Customer that violates this Acceptable Use Policy, without prior notice and without refund.

The Service, including all software, code, algorithms, designs, and trademarks, is and remains the exclusive property of Decern and its licensors.

You retain all ownership rights in your Customer Data, including ADR files, code diffs, and evidence records. By using the Service, you grant Decern a limited license to process your Customer Data solely to provide the Service.

Any feedback or suggestions you provide may be used by Decern without obligation or compensation.

You are solely responsible for the accuracy, quality, and legality of all Customer Data, including the content of your ADR files and the configuration of enforcement rules.

You are responsible for maintaining independent backups of your Customer Data. Decern does not guarantee against data loss.

Evidence record retention periods are configurable per workspace. Upon termination, data may be deleted after a 30-day grace period.

The gate uses a customer-provided large language model (BYO LLM) for ADR evaluation and signal detection. You connect your own API key to a provider of your choice (OpenAI, Anthropic, or any OpenAI-compatible endpoint).

Decern does not control or guarantee the output, accuracy, or reliability of any LLM provider. LLM outputs are probabilistic and may contain errors.

THE GATE IS AN ENFORCEMENT TOOL THAT DEPENDS ON LLM EVALUATION. It does not replace human judgment or code review. You are solely responsible for all decisions made based on gate verdicts.

Decern is not liable for any damages arising from reliance on gate verdicts, whether in observation or blocking mode.

When using BYO LLM, you are responsible for compliance with the provider's terms of service. Code diffs and ADR content are transmitted to the LLM provider for analysis.

The gate may block pull requests based on configured rules and LLM evaluations. You are responsible for configuring enforcement rules. Decern is not liable for workflow disruptions caused by enforcement actions.

Enterprise plan features (draft ADR generation) use a Decern-managed LLM. The same disclaimers about LLM output accuracy apply.

Enterprise customers may deploy the Service on their own infrastructure. Specific terms are governed by a separate agreement.

For self-hosted deployments, the Customer is responsible for infrastructure, backups, security, and compliance.

Self-hosted deployments require BYO LLM. No data leaves the Customer's infrastructure unless explicitly configured.

Decern provides the software as-is for self-hosted deployments. Dedicated support with SLA is provided per the applicable support agreement.

Decern makes commercially reasonable efforts to maintain Service availability. The Service is provided on an as-available basis.

The Service may be temporarily unavailable due to maintenance, third-party outages, or force majeure.

Support levels: community support for Free, dedicated support with SLA for Enterprise.

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND. DECERN DISCLAIMS ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

DECERN DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT LLM-BASED EVALUATIONS WILL BE ACCURATE OR COMPLETE.

Gate verdicts depend on LLM quality. The Customer acknowledges that evaluation accuracy varies by model and accepts responsibility for model selection.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, DECERN SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM THE SERVICE.

DECERN'S TOTAL LIABILITY SHALL NOT EXCEED THE GREATER OF: (A) FEES PAID IN THE PRECEDING 12 MONTHS; OR (B) €100.

Decern has no liability for: (a) actions based on gate verdicts; (b) blocked PRs and downstream effects; (c) data transmitted to LLM providers; (d) Customer Data loss.

You agree to indemnify Decern from claims arising from: (a) your use of the Service; (b) your Customer Data; (c) your violation of these Terms or applicable law; (d) your violation of third-party rights.

You may terminate your account at any time via account settings or by contacting opensource@decern.dev.

Decern may suspend or terminate access at any time for violation of Terms, non-payment, or abuse.

Upon termination, your license terminates immediately. Surviving provisions include Intellectual Property, Warranties, Liability, Indemnification, and Governing Law.

Each party agrees to keep confidential non-public information disclosed by the other party.

Exceptions: publicly available information, independently developed information, or information required to be disclosed by law.

Decern processes personal data in accordance with applicable data protection laws, including GDPR where applicable.

For BYO LLM, code diffs may be transmitted to the customer's chosen LLM provider. Decern is not the data controller for data processed by third-party providers.

Decern implements commercially reasonable security measures to protect Customer Data.

Decern may modify these Terms at any time. Material changes will be communicated with at least 30 days' notice.

Continued use after modification constitutes acceptance of revised Terms.

These Terms are governed by the laws of Italy. Disputes are subject to the exclusive jurisdiction of Italian courts.

Both parties agree to attempt good-faith negotiation for at least 30 days before legal proceedings.

If any provision is held invalid, the remaining provisions continue in full force.

These Terms, together with the Privacy Policy and any Enterprise agreements, constitute the entire agreement regarding the Service.
