Build 04 privacy policy
What Build 04 collects, how it uses Google data, who else sees anything, and how to delete it.
Last updated 10 November 2026. Build 04 (build04.com) is a product of Linkrra LLC, a Wyoming limited liability company, which is the data controller. Contact [email protected].
What Build 04 is
Build 04 creates a website for a small business from a short description, lets the owner edit it in conversation and publish it. Owners on Build Plus can also connect their own Google account so that enquiries from their website are emailed to them from their own Gmail and appointment requests are booked in their own Google Calendar.
The short version
We collect what we need to run your account, your websites and the features you switch on. Connecting Google is optional. We use Google data only to do the things you asked Build 04 to do, we never read your inbox, we do not sell any data, we do not use it for advertising, and we do not use Google user data to train AI models.
Information we collect
Your Build 04 account: when you sign in with Google we receive your name, email address and profile picture (the openid, email and profile permissions). We never see your Google password.
Your websites (including guest drafts): the descriptions and edits you give Build 04, the pages it generates, your business details, and what visitors submit through your site's forms (for example a name, email address, phone number, message, or a requested appointment time).
Google connection (optional): the Google email address you connected, the list of permissions you approved, and encrypted access and refresh tokens.
Billing: your plan, payments and Stripe's references for them. Card details are handled by Stripe and never reach our servers.
Sessions: essential cookies keep you signed in or let you return to your guest drafts. We record edit usage to apply your allowance. Signing in links your guest drafts and usage to your account.
How Build 04 uses Google user data
Connecting Google is a separate, optional step for website owners. When you connect, Build 04 asks for exactly these permissions and uses them only as described:
Send email on your behalf (gmail.send) — when a visitor submits a form on your website, Build 04 sends that submission to the notification address you chose, from your own Gmail account. Build 04 can only send; it cannot read, search, change or delete anything in your mailbox, and it sends nothing you did not set up.
View and edit events on your calendars (calendar.events) — when a visitor requests an appointment on your website, or you ask your Build 04 assistant to book one, Build 04 creates that event in the calendar you chose. When you ask your assistant what is on your calendar today or tomorrow, Build 04 reads the time and title of those events and shows them only to you.
View your availability (calendar.freebusy) — before booking, Build 04 checks whether the requested time is free, so it never double-books you. It sees only busy/free time, not event details.
We store the result of each action (for example "email sent" with Gmail's message id, or "event created" with Calendar's event id) so you can see that it happened. We do not copy your mailbox or your calendar into our systems.
Limited Use
Build 04's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. In particular:
• We use Google user data only to provide and improve the user-facing features described above, which are visible in Build 04.
• We do not transfer Google user data to others except as needed to provide those features (for example, delivering your own appointment list to the WhatsApp number you paired with your assistant), to comply with law, or as part of a merger or acquisition with notice to you.
• We do not use or transfer Google user data for serving advertisements, including retargeting, personalised or interest-based advertising.
• We do not sell Google user data, and we do not use it to determine credit-worthiness or for lending.
• No person at Linkrra reads Google user data unless you give us explicit permission for a specific message or event (for example to investigate a problem you reported), it is needed for security purposes such as investigating abuse, it is required by law, or it is aggregated and anonymised for internal operations.
• We do not use Google user data, including data obtained through Google Workspace APIs, to develop, improve or train generalised or non-personalised artificial-intelligence or machine-learning models.
AI processing
Build 04 uses AI models to write and edit your website and to understand the messages you send your Build 04 assistant. Website text and assistant messages are processed by models that Linkrra operates; request content is not kept by the serving software and is not used to train models. Google user data is not sent to AI models to train them.
Who else processes data
Google — sign-in, and the Gmail and Calendar actions above when you connect them.
Stripe — payments.
Cloudflare — network delivery, security and domain registration you request.
Meta (WhatsApp) and Twilio — only if you switch on the WhatsApp assistant, reminders or the voice receptionist on Build Plus, to deliver those messages and calls.
We disclose data to authorities only where a valid legal order requires it.
How long we keep it and how it is protected
Google tokens are encrypted at rest (AES-256-GCM) and are kept only while your Google connection exists. Account and website data are kept while your account exists. Billing records are kept as long as tax and accounting law requires. Sessions expire after 30 days. All traffic is encrypted in transit (HTTPS).
Your choices: disconnect and delete
You can disconnect Google at any time from your project's settings in Build 04 or from your Google Account permissions page; Build 04 then stops all Gmail and Calendar actions and we delete the stored tokens. To delete your Build 04 account and its data, write to [email protected]; we delete it within 30 days, except what the law requires us to keep, and tell you what is left and why. If you are in the EU or UK you also have rights of access, correction, portability and erasure.
Children
Build 04 is not for anyone under 16.
Changes
If we change how Build 04 uses Google user data, we will update this page and ask for your consent again before using data in a new way.
