PLEASE READ THIS AGREEMENT CAREFULLY BEFORE INSTALLING OR USING SOTTO. BY CLICKING "I AGREE," DOWNLOADING, INSTALLING, OR USING THE SOFTWARE, YOU AGREE TO BE BOUND BY THESE TERMS. IF YOU DO NOT AGREE, DO NOT INSTALL OR USE SOTTO.
This End User License Agreement ("Agreement") is a legally binding contract between you ("Researcher" or "you") and KonnectXR, LLC, a Minnesota limited liability company doing business as Kaperi Labs ("KXR," "we," "us"), for use of the Sotto Solo desktop application and any related documentation (collectively, the "Software"). This Agreement supplements our Terms of Service and Privacy Policy; for the Software, this Agreement controls in the event of a conflict.
Subject to this Agreement and payment of applicable fees, KXR grants you a limited, non-exclusive, non-transferable, revocable license to install and use up to two (2) copies of the Software on up to two (2) computers for your personal academic research purposes.
This license does not include the right to:
Sotto Solo is offered as a subscription at $30 per month or $350 per year (USD), following a 14-day free trial, managed through Lemon Squeezy (lemonsqueezy.com). The subscription auto-renews at the then-current price unless cancelled before renewal; you may cancel at any time, effective at the end of the current paid period. Prices are exclusive of applicable taxes, which the commerce provider handles. KXR may change pricing with reasonable advance notice to current subscribers.
Trial start. The 14-day trial begins when you activate a trial license key through Lemon Squeezy, not on the date of first launch. Before the trial converts to a paid subscription, we will send you notice as required by law.
Trial expiration and soft-lock. Upon expiration of the trial without purchase, the Software enters a read-only state: you may view existing research data but may not start new analyses, transcriptions, or writing sessions, and a clear upgrade prompt is shown. KXR does not delete, corrupt, or render inaccessible any data you created.
Offline grace. If your device is offline, the Software continues to operate for a 7-day offline grace period, after which it must reconnect to re-validate the license before continued use.
During the trial, usage analytics (PostHog) are enabled and cannot be disabled; by activating a trial license you consent to this collection. On a paid license, analytics are on by default and you may turn them off at any time in Settings (see Section 7 and the Privacy Policy).
5.1 Included cloud services. Sotto's academic writing assistant uses Anthropic (Claude) for literature search and writing assistance, on your behalf, using API credentials maintained by KXR. You do not need separate accounts or API keys with Anthropic.
5.2 Researcher review gate. Before any data is transmitted to an external API, Sotto displays the exact payload, requires your explicit approval, and logs the approval and transmission to a local audit trail you can export. You are responsible for reviewing payload content before approving transmission.
5.3 Data transmitted. Raw participant data (transcripts, recordings, participant identifiers, and raw qualitative data) is processed locally and is not transmitted to cloud APIs. Approved cloud calls involve researcher-composed queries, research questions, theme summaries, and draft writing content. KXR cannot guarantee that content you include in an approved payload is free of participant information; you are responsible for reviewing payloads before approval.
5.4 Third-party terms. KXR is the contracting party with Anthropic. Anthropic's own privacy policy and terms govern how it processes data received through its API; KXR's privacy commitments do not extend to that provider.
5.5 Usage limits. KXR bears the cost of API calls made through the Software and may implement fair-use limits per license. If implemented, limits will be disclosed in the Software and on the website with reasonable advance notice.
Sotto uses third-party AI models (for example, Llama, Mistral, or Gemma) that run locally on your device via a model runtime such as Ollama. KXR does not distribute or bundle these model weights with the Software; you obtain them separately, directly from their providers, and your use of each model is governed by that model's own license and acceptable-use terms (for example, the Meta Llama Community License and Acceptable Use Policy, or the Google Gemma Terms of Use). You are responsible for reviewing and complying with those terms.
The Software also includes or relies on open-source components provided under their own license terms; a list of those components and their notices is available in the app under Settings, then Legal Notices.
What KXR collects: feature-usage events, navigation patterns, session counts, an anonymized device identifier (one-way SHA-256 hash of a machine ID), Sotto version, OS, Electron version, and selected local-model tier, via PostHog.
What KXR never collects: research data (transcripts, participant information, coding results, field notes, or document content), local-model prompts or responses, file/project/folder names, or free-text input of any kind.
Consent by license state: trial users' analytics are enabled and cannot be disabled; paid users have analytics on by default and may turn them off at any time in Settings.
First-launch disclosure. The Software displays a non-dismissable disclosure on first launch (after license activation) explaining these practices and linking to the Privacy Policy; you must acknowledge it to proceed.
8.1 Local data. Your research data is stored on your machine; KXR does not have access to it. You are solely responsible for backing up your data and complying with your institution's data-governance requirements.
8.2 IRB compliance. Sotto is designed with IRB-compliance considerations in mind (local processing, a researcher-controlled transmission gate). However, KXR makes no representation that the Software meets the specific requirements of your institution's IRB protocol. IRB compliance is the researcher's responsibility. Confirm with your IRB office whether your use of Sotto is covered by your approved protocol.
The Software and all intellectual property rights in it are and remain the sole and exclusive property of KonnectXR, LLC. This Agreement transfers no ownership to you. You own the research data and outputs you create using the Software, but not any component of the Software itself.
Depending on your operating system and settings, you may receive a security warning when installing Sotto (e.g., Windows SmartScreen or macOS Gatekeeper). KXR is pursuing code-signing certification. If you receive such a warning, verify that you downloaded Sotto from an official source (sottolab.com or the official GitHub Releases page) before proceeding.
The Software checks for updates from GitHub Releases; update checks transmit no user data. By using the Software you consent to automatic update checks; you may also check manually via Settings. KXR may push critical security updates without prior notice.
THE SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. KXR DOES NOT WARRANT THAT THE SOFTWARE WILL SATISFY THE REQUIREMENTS OF ANY SPECIFIC INSTITUTIONAL IRB PROTOCOL OR DATA-GOVERNANCE POLICY, OR THAT OUTPUT WILL BE ACCURATE.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, KXR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATING TO THIS AGREEMENT OR YOUR USE OF THE SOFTWARE. KXR'S TOTAL LIABILITY FOR DIRECT DAMAGES SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM.
KXR may terminate this Agreement immediately if you breach it. Upon termination, your license is revoked and you must cease all use and delete all copies. Your research data remains on your machine and is not deleted by KXR. Sections 8, 9, 12, 13, 15, and 16 survive termination.
This Agreement is governed by the laws of the State of Minnesota, without regard to conflict-of-law principles. The dispute-resolution provisions in Section 17 of the Terms of Service (informal resolution, binding arbitration, class-action waiver, small-claims and injunctive-relief carve-outs, a 30-day opt-out, and a savings clause) apply to disputes under this Agreement and are incorporated by reference. Venue is Sherburne County, Minnesota.
Entire agreement: This Agreement, the Terms of Service, and the Privacy Policy at www.sottolab.com constitute the entire agreement regarding the Software. Amendments: KXR may update this Agreement; material changes will be communicated in the application, and continued use after acknowledgment constitutes acceptance. Severability: If any provision is unenforceable, the rest remains in effect. No assignment: You may not assign this Agreement without KXR's written consent.
