Privacy Policy
Last updated August 2026
Wren is run by Household COO, Inc., 131 Continental Dr, Suite 305, Newark, DE 19713. This policy explains what we collect, why, and what we do not do.
The short version: we use a household's information to reduce that household's mental load, and for nothing else. We do not sell it and we do not use it to build a profile of anybody.
What we collect
What you tell us
Your name, email address and mobile number, and the identifier Google gives us when you sign in with it. The names of the people, pets and things in your household, and any dates you record about them. The to-dos you create and anything you write on them, including a checklist or a cost.
What you say to Wren
Everything you type or text to Wren is stored, along with what Wren made of it. That is what lets Wren answer a follow-up rather than starting over each time. Messages you send to support are stored the same way, so that a person can read them and reply.
What you connect
If you connect Google Calendar, we read the events on the calendars you choose: their titles, dates, times and locations. We store a short summary of each and keep the original in our own storage. We keep the Google address you connected and an encrypted token that lets us keep reading. We do not read your email through Google.
If you forward an email to your household address, or send us a photo of a flyer or a letter, we read it to work out what needs doing.
What your device tells us
A push token, so notifications reach your phone. Which platform you are on and which version of the app you are running.
What we notice about reminders
When a reminder was sent, whether it was delivered, whether you opened it, and whether the to-do got done. That is what stops the product nagging: something asked three mornings running and ignored is a question that should stop being asked, and it cannot know that without noticing.
When you correct us
When you change something Wren worked out, such as renaming a to-do that was described badly or moving a date that was read wrong, we keep the original and what you changed it to. That is how Wren's judgment gets better. It is not used to build a picture of you.
What the app reports when it breaks
When something goes wrong in the app, it sends us the error: what failed, where in the code, which version you are running and which screen you were on. An error message can quote the wording of a to-do. This is our own reporting, going to our own systems. No third party crash reporting service is involved.
Analytics
We use Google Analytics and Firebase to understand how the app is used in aggregate: which screens people reach, where they stop, whether a feature is used at all. This is about the product, not about you.
How we use it
To find what is coming, work out what needs doing about it, decide who should do it, and tell that person in time. To send the reminders you asked for. To answer you when you write to support. To keep the service working and to fix it when it breaks.
We send what you give us to a language model to interpret it. That is how a school email becomes a to-do with a date on it. The model provider processes it on our instruction and does not use it to train models.
Marketing
We will never send you marketing unless you have separately and deliberately chosen to receive it. Creating an account is not that choice. Reminders you set up are not marketing, and turning marketing off never turns those off. If you do opt in, we use Klaviyo to send it, and every message carries a way to stop.
Who else sees it
Other adults in your household see what is shared with the household. A to-do you made for yourself stays yours until you share it.
Outside the household, only the services that make the product work:
- Amazon Web Services, where everything is stored and runs.
- Anthropic, which interprets what you send us.
- Google, for sign-in and calendar, and for analytics.
- Twilio, which delivers text messages.
- Expo, which delivers push notifications and app updates.
- Klaviyo, only if you opt in to marketing.
We do not sell your information to anybody, for any purpose.
How it is protected
Financial information, if you ever connect an account, is stored separately from everything else. We never store bank credentials: connecting an account gives us a token from Plaid, held in a secrets manager, and nothing more.
Google calendar tokens are encrypted. Access to the database is limited to the people who need it.
How long we keep it
Your information stays while your account is open. Photos and forwarded messages you send us are kept for 30 days after we have read them, and are then deleted.
When you delete your account, we schedule the deletion a few days out rather than doing it at once, so that you can undo it. After that your information is removed from our systems, and from our backups within thirty days.
Your choices
Disconnect Google at any time in Settings. Turn any kind of reminder off in Settings. Reply STOP to any text message. Delete your account in Settings, which takes your own information and leaves the household standing.
To ask what we hold about you, or to have it corrected or removed, write to support@householdcoo.app. We act on a request to delete within three business days.
Children and teenagers
Creating a household requires being 18. Joining one you have been invited to requires being 16, because a parent inviting a teenager into the household is a normal use of this product. We do not knowingly let anybody under 16 hold an account, and we do not knowingly collect information from them.
Households do record information about their own children, including children well under 16: a name, a birthday, the fact that somebody is dropped at daycare on Tuesdays. That is a parent's information about their own family, entered by the parent, and it is treated like everything else described here. It is never used to build a profile of a child and it is never sold.
Where we operate
Wren is offered in the United States, and information is stored in the United States.
Changes
If we change this policy in a way that matters, we will tell you in the app before it takes effect.
