The deal, without the legal voice.

Last updated September 12, 2026. These terms are between you and 678 Agency LLC ("RostrLab", "we"), Brooklyn, New York. Using the product means you agree to them.

What you are buying

RostrLab builds and runs a working web application for you (a Creator OS or a Company OS) from the brief you give us, hosts it, keeps it maintained, and supports it. It is a service, not a download. You get a login, your own address on our domain, and the pages and features described on the site at the time you sign up.

How it works

Creator OS: you answer a short brief, your product is generated around it within minutes and tuned by hand over the following days, and it opens when your first $29 a month payment clears. Keeping it after that is $29 a month, cancel any time; a review of it in your first month puts the next month on us. If you do not keep it, it switches off and nothing is owed. Company OS: you answer a short brief, it is live the same minute and tuned by hand over the first few days, and your team uses it free for 14 days; then $99 (Run) or $199 (Pro) a month, invoiced, cancel any time. You get an email the moment it is ready. Until then you can add to your brief; after that, everything works.

Prices and payment

Creator OS: $29 a month from the day it opens, cancel any time, and a full refund on request within the first 7 days. Everything in: hosting, every fix, every update, every new feature, and your own address. Never a commission or a cut of your deals. Paid by card through Stripe, cancel any time from Setup; the month already paid runs to its end.
Company OS: free for 14 days after delivery. Then $99 a month (Run) or $199 a month (Pro), invoiced monthly through Stripe, net 15, paid by card or bank transfer. No build fee, never a commission. Cancel any time; the month already invoiced runs to its end.
Prices are in US dollars and exclude any taxes you owe. We may change prices for new customers at any time; your price does not change while you keep paying it.
If a monthly payment fails, we tell you and retry. After 14 days without payment the account becomes read-only until it is settled.

Refunds and cancelling

Creator OS has no build fee, so there is nothing to refund before you subscribe. Once you are paying, cancel any time from Setup; if a month was charged in error, say so and it comes back to your card. No questions asked.
Cancelling stops the plan at the end of the month you have paid for, with no partial-month refunds.
If we told you something was included and we cannot deliver it, we refund that month. Tell us within 30 days.
Company OS has no build fee either; the 14 free days are the trial. If we miss the delivery window, tell us and the first paid month is on us.

What the monthly covers, and what it does not

Hosting, backups, security updates, uptime, every fix, every product update, and small tweaks (wording, a rate, a field, a setting). Bigger changes and new features (a new page, an integration, a redesign) are quoted in writing first, usually $50 to $300, and nothing is billed without your yes. We answer support tickets within one business day and ship fixes the same week; this is a promise we work to, not a guarantee with penalties attached.

Your data and your content

Everything you put in is yours. We get only the permission we need to run the product for you.
You can export it at any time and take it anywhere. Ask and we send you the whole thing.
Emails you send through RostrLab go out under your name. You are responsible for what they say. Do not use it to send spam or anything unlawful.
Media kits you publish are public. Only publish numbers and claims that are true; brands rely on them.
We do not use your data to train models, sell it, or show it to other customers. See the privacy policy.

Fair use

Do not try to break into other accounts, scrape the service, resell it, or use it for anything illegal. Do not send unsolicited bulk email from your RostrLab address; email providers will block it, and we will suspend the account to protect everyone else.

Uptime and support

We aim for the product to be available all the time and we monitor it around the clock. Planned maintenance is announced in advance and done at quiet hours. If the product is down for more than 24 hours in a month because of us, that month is free. Support is by ticket from inside the product or at rostrlab.com/support.

Ending things

You can close your account any time. We can close an account that breaks these terms, after telling you why and giving you a chance to fix it unless the problem is serious. Either way, you can export your data first.

The legal part

The product is provided as it is. We work hard to keep it accurate and available, but we do not guarantee it will be error-free, and we are not responsible for decisions you make based on it, including rates you charge or deals you sign.
Our total liability to you for anything arising out of the service is limited to what you paid us in the 12 months before the claim.
These terms are governed by the laws of the State of New York. Disputes are handled in the courts of Kings County, New York, unless the law says otherwise.
If a part of these terms is found unenforceable, the rest still applies.

Changes

If we change these terms in a way that matters, we email account holders before the change takes effect. Continuing to use the product after that means you accept the new terms.
