Privacy Policy

1. Overview

This Privacy Policy describes how Archidian LLC ("Archidian") collects and manages your information. By using the Service, you consent to the data practices described herein.

2. Data Collection & Google User Data

We collect information to provide our services, including:

• Account Information: Name and email address.
• Google User Data: When you use "Sign in with Google," we collect your Google ID, email address, and basic profile information (name and profile picture).
• Construction Documents: Files you manually upload for analysis.
• Billing Information: For paid plans, billing information (name, billing address, and payment method details) is collected and processed by our payment processor, Stripe. Archidian does not store full payment card numbers; we receive only limited billing metadata (such as card brand, last four digits, and subscription status) needed to manage your account.

3. Use of Data and "Limited Use" Disclosure

Archidian's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

We use your Google data only to authenticate your identity, create your account, and personalize your user experience. We do not use this data for any other purpose.

4. AI Processing & Training Restrictions

Archidian utilizes third-party AI sub-processors to analyze content manually uploaded by users.

• No Training on Your Data: Your uploaded Construction Documents and related analysis data are never used to train, fine-tune, or improve any AI or machine learning models, whether by Archidian LLC or any third-party AI sub-processors. Third-party AI services used to process Construction Documents are configured for zero data retention and no training on customer content, except for transient processing necessary to provide the Service.
• Transient Processing Only: Your content is processed in a transient state solely to deliver analysis results back to you. It is not stored by our AI sub-processors beyond the time needed to complete processing.
• Google User Data: Archidian does not use data obtained via Google APIs to train, improve, or fine-tune any AI or ML models. Your Google profile information is used strictly for authentication and account management.

6. Internal Access for Troubleshooting and Support

To ensure the reliability of the Service, authorized Archidian personnel may occasionally need to access or view your uploaded Construction Documents and processing logs. This access is strictly limited to:

• Resolving customer support requests initiated by you.
• Investigating and debugging system errors, parser failures, or processing anomalies.
• Ensuring the security and stability of our infrastructure.

Strictly No AI Training: Under no circumstances will human review of your documents be used for data labeling, manual model fine-tuning, or training any machine learning models. Access is restricted to authorized engineering personnel on a strict need-to-know basis, and all internal access is bound by strict confidentiality agreements.

7. Data Deletion & Security

You retain 100% ownership of your content. You may request account or data deletion at any time by contacting [email protected]. We employ industry-standard encryption for data in transit and at rest.

8. Communications

We use the contact information you provide to communicate with you about your account, including service-related and transactional messages (such as processing notifications, billing receipts, and security alerts). From time to time we may also reach out with product updates, news, or offers we think may interest you.

You can opt out of non-essential communications at any time by replying to any such email or by contacting [email protected], and we will stop sending them. Essential account and service messages may still be sent as needed to operate the Service.
