These Terms of Service (“Agreement”) govern your access to and use of Plainwork, a cloud-based note-taking and knowledge management service operated by Sidefort Inc. (“Plainwork”, “Provider”, “we”, or “us”). By creating an account or using the service, you (“Customer”, “you”) agree to be bound by this Agreement.

1. Service

1.1 Access and Use

During your Subscription Period and subject to the terms of this Agreement, you may access and use the Plainwork cloud service and copy and use the included software and documentation only as needed to access and use the service, in each case for your internal business or personal purposes.

1.2 Support

During your Subscription Period, Plainwork will provide technical support as described in your plan.

1.3 User Accounts

You are responsible for all actions on your users’ accounts and for all users’ compliance with this Agreement. You and your users must protect the confidentiality of passwords and login credentials. You will promptly notify Plainwork if you suspect or know of any fraudulent activity with your accounts, passwords, or credentials, or if they become compromised.

1.4 Feedback and Usage Data

You may, but are not required to, give Plainwork feedback, in which case you give feedback “AS IS”. Plainwork may use all feedback freely without any restriction or obligation. In addition, Plainwork may collect and analyze usage data, and may freely use usage data to maintain, improve, enhance, and promote its products and services without restriction or obligation. However, Plainwork may only disclose usage data to others if the usage data is aggregated and does not identify you or your users.

1.5 Customer Content

Plainwork may copy, display, modify, and use your content only as needed to provide and maintain the product and related offerings. You are responsible for the accuracy and content of your content.

1.6 AI Services

Plainwork may include artificial intelligence or machine learning features as part of the product (“AI Services”). You may use AI Services by providing Input. The AI Services may generate Output in response to Input. Plainwork may copy, display, modify, distribute, and use Input to the extent necessary to provide the AI Services. You authorize Plainwork to process Input for all such purposes.

1.7 Model Training

Plainwork will not use your Input, Output, or Customer Content to train any AI or machine-learning model. Plainwork may use Input, Output, and usage data to provide, maintain, develop, and improve the AI Services through non-training means (such as monitoring performance, debugging, and improving service reliability), but such usage will not constitute training of any model.

1.8 Non-AI Data Use
