Chatelain

A private assistant for managing one household.

Chatelain keeps track of everything your home asks you to remember.

Chatelain is a personal home-management application. It builds a private, organized record of a single household — its appliances and vehicles, its bills, warranties, receipts, documents, vendors, and the deadlines that are easy to forget — and it surfaces the few things that actually need your attention, so nothing important slips.

What Chatelain does

• Keeps an inventory of your home's appliances, vehicles, and important documents.
• Tracks bills, warranties, returns, service appointments, and renewal deadlines.
• Reads receipts and confirmation emails you receive so it can log purchases, warranties, return windows, and appointments automatically instead of asking you to type them in.
• Reminds you, in one place, of what needs to be done and when.

Why Chatelain asks to connect your Google account

If you choose to connect a Google account, Chatelain reads your Gmail messages on a read-only basis to find household-relevant information — such as order receipts, warranty and return notices, vendor charges, and appointment confirmations — and turns them into entries in your private household record. Chatelain uses this access only to provide that feature to you. It does not sell your data, does not use it for advertising, and does not use it to train AI models. You can disconnect at any time. See our Privacy Policy for full detail, including our compliance with the Google API Services User Data Policy.

How it's built

Chatelain is designed to run privately for one family, without advertising or selling data. Your information stays yours.
