This independent Detroit Home Repair Assistant demo helps residents explore critical home repair resources. It is operated by The Understanding Company and is not an official City of Detroit service.
Information we collect
You do not need an account. We set a signed, HTTP-only guest-session cookie so your browser can keep a guest session and so we can enforce basic usage limits.
We store the messages you send, guided-intake answers, tool results, and source links for up to 30 days so you can reload the conversation. Saved chat records exclude file payloads, private model reasoning, and internal resume tokens.
If you attach a photo or document, AWS services process it to extract repair-related text. The file can be staged temporarily in encrypted AWS storage. We try to delete the staged file immediately after processing. If cleanup fails, it stays in the storage account until the account owner or a retention policy removes it. Do not upload Social Security numbers, banking or login credentials, or full financial documents.
Hosting and security systems may collect ordinary technical logs, such as request time, browser type, network information, and errors.
How we use your information
We use this information to answer repair questions, continue your chat, retrieve public resources, prevent abuse, troubleshoot errors, and improve reliability.
We may use aggregated, de-identified data to understand how people use the assistant and to improve the product. We do not sell your personal information.
Sharing with others
Vercel hosts the web application. Amazon Web Services provides AI processing and storage, including Amazon Bedrock, Bedrock Data Automation, Guardrails, S3, and DynamoDB. These providers process data to operate the demo under their service agreements.
The newsletter form submits your email directly to the City of Detroit's GovDelivery service. The Understanding Company does not receive or store that address through the form. The City and GovDelivery terms apply to that subscription.
We may disclose information if required by law, to protect safety, or to enforce our terms.
Retention and security
The guest-session cookie expires after 30 days. Saved conversations are not available through the assistant after up to 30 days by default. DynamoDB removes expired records in the background, so final deletion can occur later. We try to remove temporary attachment staging after extraction. Service logs may be kept longer when needed for security, debugging, or legal obligations.
We use reasonable safeguards to protect your data, but no online service can guarantee perfect security.
Your choices
Starting a new chat clears the current conversation from this tab but does not immediately erase its saved record. You can clear the guest cookie in your browser. To ask us to remove a chat from the app before it expires, email support@theunderstanding.company and include the conversation URL. We review and verify each request. Final removal by service providers can occur later.
You can stop using the demo at any time. The assistant does not submit a program application or check or change an application status on your behalf.
Children
The assistant is not intended for children under 13. We do not knowingly collect personal information from children under 13.
Changes to this policy
We may update this policy from time to time. When we make material changes, we will post the updated policy on this page and update the effective date above.
