Halfdoor terms of service

Last updated 2026-11-08

These terms cover Halfdoor, its paid plan and Ask. Everyone accepts them on the consent page; the member who starts the paid plan also agrees to them on the billing page. Please read them with the privacy page.

Who we are

Halfdoor is run by HomeLinq.
Contact: admin@halfdoor.ai

What Halfdoor is

A household's shared memory, used from each person's own AI assistant, such as Claude or ChatGPT.
Mine is private to you. Home is shared with everyone in your household.
The checked home record holds facts about your home. Only Halfdoor writes it, after checking each fact.
Community notes are Halfdoor's own short summaries of sources about the community your home is in, each with its source and date.
Halfdoor is used mainly from your own assistant, a separate service under its own terms. Halfdoor also offers Ask, an optional AI answer on the members page, run on Anthropic's model.
Halfdoor is not responsible for what an assistant says, or for what it does with what it reads.

Not professional advice

Record facts and community notes are information to help you. They are not a warranty, an inspection, or legal or safety advice.
They can be out of date or wrong.
Before acting on anything safety-related (gas, electrical, water shutoffs) or costly, check with a qualified professional or the official source.
If you find a mistake, tell Halfdoor at the contact address.

Ask

Ask's answers come from an AI model using only your household's checked record and community notes.
They can be wrong, incomplete or out of date. They are not an inspection, a warranty, or legal or safety advice.
Check the record page, and check with a qualified professional before gas, electrical, water or costly work.
Ask is free. It has daily limits, and Halfdoor may pause or limit it.
Halfdoor keeps no copy of your questions or the answers.

Who can use it

You must be 18 or older.
You sign in with Google. Keep your Google account secure.
You join a household only when Halfdoor adds you or a member invites you.
For now, a person can be in one household at a time.

Your content

You keep ownership of what you save.
You let Halfdoor store it and show it to the people who can see it: Mine to you alone, Home to everyone who is a member now or joins later. Halfdoor's own access is on the privacy page.
Do not save passwords or other secrets, full account or ID numbers, or anything you do not have the right to share.
Halfdoor does not edit or delete your lines, except that it resizes and re-encodes photos you upload, as the privacy page describes. Only you can forget your lines, and any member can hide a Home line.
You can upload photos and PDF documents on the members page; the same rules apply to them as to your lines.
If content breaks these terms or the law, Halfdoor may suspend or remove the person who saved it.

Acceptable use

Do not try to reach another household's data, or to get around Halfdoor's access controls.
Do not disrupt the service, scrape it, or use it for anything illegal.
Use Halfdoor through your own assistant or the members page, not for automated mass use.

The paid plan

The plan pays for Halfdoor checking your home: a visit where Halfdoor reads your equipment labels and types in the details (no photos are kept), and keeping the record current with new equipment and service visits while the plan is active.
Reading the record never needs the plan: members see it on the record page, download it in the export, and read it through their assistants, with or without one. Community notes, and saving and recalling lines, are free.
Without an active plan, Halfdoor adds nothing new to the record. Halfdoor still corrects a wrong fact, marks an item no longer in the home, and deletes the record when a current member asks.
Before you start, the billing page and Stripe's checkout show the price, the renewal period and the trial length.
Payment goes through Stripe. Halfdoor never sees card numbers.
The trial needs no card and is once per household. If no card is added by its end, it ends by itself.
With a card, the plan renews automatically each period until cancelled.
Stripe emails a reminder before the trial ends and before each renewal.
The member who starts the plan pays for it. Only they can manage or cancel it, at any time, from the billing page, where Manage billing opens Stripe's page.
If that member leaves the household, the plan continues until they cancel it. They can still cancel it after signing in.
Cancelling stops the next renewal. A paid period stays active until it ends; cancelling during the trial can end it at once.
If a payment fails, Halfdoor pauses new checks and updates until the card is updated. Reading the record, corrections and deletion continue.
A price change applies only from a later renewal, and Halfdoor announces it at least 30 days before.

Refunds

If you ask within 14 days of a charge, Halfdoor refunds that charge in full and ends the plan.
After that, charges are not refunded, but you can cancel any time so the plan does not renew.
Ask through the contact address.
Nothing here limits rights you have under the law.

Leaving, suspension and ending

You can leave your household at any time on the members page.
When you leave, your Mine stays yours, and the Home lines you saved stay with the household. Forget any Home line you want removed while you are still a member.
You can download your own data from the export, even after leaving.
Halfdoor may suspend or end your access if you break these terms, or to protect other people. It tells you why, unless the law or safety prevents it.
What Halfdoor keeps, and for how long, is on the privacy page, including database backups for up to 30 days.

The service as offered

Halfdoor is a new service run by a small team.
It is provided "as is", and it may change, pause or stop.
Halfdoor gives notice before stopping the service or removing a paid feature.
If Halfdoor ends the paid plan early, it refunds the unused part of the paid period.

Liability

To the extent the law allows, Halfdoor is not liable for indirect or consequential losses.
Halfdoor's total liability is limited to what you paid Halfdoor in the 12 months before the claim.
Nothing here limits liability that the law does not allow to be limited.

Changes to these terms

Halfdoor posts changes here with a new date.
Halfdoor tells members before a material change takes effect, at least 30 days before.
Continuing to use the paid plan after that means you accept the change. You can cancel instead.

Governing law

These terms are governed by the laws of the State of Texas, USA.
