Agreement Overview
These Terms of Service ("Terms") govern your access to and use of EvidenceLog for Jira and services provided by Langtago Studio ("Langtago"). By installing EvidenceLog from the Atlassian Marketplace, using our site, or subscribing to our software, you agree to be bound by these Terms and the Atlassian Customer Agreement.
1.Subscription, Billing & Marketplace Licensing
EvidenceLog for Jira is licensed on a subscription basis through the Atlassian Marketplace. Subscriptions are billed directly through your Atlassian Cloud invoicing agreement:
- Free Developer Tier: Fully functional for teams up to 10 users with single-issue certification, SHA-256 fingerprinting, and offline verification.
- Standard & Enterprise Tiers: Includes project-level Audit Hub, 1-Click Batch Certification, Preventive Workflow Gatekeepers, Release Merkle root proofs, and custom compliance policy configuration.
- Billing Terms: Handled by Atlassian Pty Ltd pursuant to the Atlassian Marketplace Terms of Use. Renewal, payment terms, and cancellation align directly with your Jira Cloud subscription.
2.Customer Data & Audit Record Ownership
You retain 100% full, exclusive ownership of all your Jira issues, code repository links, reviewer identities, and cryptographic evidence artifacts.
Because EvidenceLog runs purely within your Atlassian Forge sandbox, all generated SHA-256 snapshots, Merkle tree trees, and compliance histories are stored encrypted within your Jira tenant. Langtago claims no ownership, title, or intellectual property rights over any compliance artifact generated from your SDLC.
3.Langtago Intellectual Property
Langtago Studio retains all intellectual property rights, trademarks, patents, and copyrights in the EvidenceLog software, verification algorithms, user interface components, and Forge backend code. You may not reverse engineer, decompile, or redistribute the proprietary software outside your licensed Atlassian organization.
4.Audit & Regulatory Guidance Disclaimer
EvidenceLog for Jira provides automated evidence collection, tamper-evident verification, and crosswalk analysis mapped against AICPA SOC 2 Type II, ISO/IEC 27001, HIPAA, and FedRAMP standards. EvidenceLog does not provide formal legal advice or substitute for the independent opinion of an accredited Certified Public Accountant (CPA) or licensed ISO certification body.Final audit certifications remain solely at the discretion of your independent external audit firm.
5.Availability, Support & SLAs
EvidenceLog for Jira executes natively on the Atlassian Forge serverless infrastructure. Application availability and runtime reliability are backed by the Atlassian Cloud SLA.

To the maximum extent permitted by applicable law, in no event shall Langtago Studio, its founders, or contributors be liable for any indirect, incidental, special, consequential, or punitive damages, or loss of profits or revenue arising out of the use or inability to use the software. Langtago's total aggregate liability arising out of or related to these Terms shall not exceed the total fees paid by you to Langtago in the twelve (12) months preceding the incident.
7.Governing Law & Severability
These Terms shall be governed by and construed in accordance with the laws of the jurisdiction specified in your commercial agreement, without regard to conflict of law principles. If any provision of these Terms is found to be unenforceable, that provision shall be limited or eliminated to the minimum extent necessary so that these Terms will otherwise remain in full force and effect.
