Zentient privacy policy

Effective date: November 4, 2026

This policy explains what personal information Ecoterium, Inc., a California corporation ("we"), collects through zentient.studio and the Zentient service, how we use it, and who we share it with. 995 Market St, Fl 12, San Francisco, CA 94103.

1. What we collect

At sign-up: your organization's legal name, the state where it is organized, and its address; your name, title and email address; and the agent name you choose or we generate.
Payments: PayPal processes your payments and holds your payment details. We receive the payment status, amount, date and PayPal's reference, and the payer name and email PayPal shares with us. We never see your card or bank numbers.
Your uploads and messages: the files you upload (for example RVT and DWG files) and the messages you send us. Drawings can name people, such as property owners, and show addresses.
Records of use: each use of your personal link, sign-ins, acceptances (the version you accepted and when), cancellations, and the emails we send you.

2. How we use it

We use it to run the service: to check your uploads and send findings and recommendations, to bill you, to send the notices the Agreement and the law require, to keep proof of your consent, and to keep the service secure. We also use what you upload, your review requests and their outcomes to improve our agents' checks, prompts, instructions and workflows, for you and for other customers. At the pilot price this is a condition of the subscription, as section 8.3 of the Agreement says; it cannot be turned off at that price. Before anything you upload enters a collection we reuse for other customers, we assess it for details that identify you, your clients or a property, for confidential information and for third-party rights; what fails is kept out of that collection. This use does not include advertising, public examples, selling your information, or letting an AI provider train its own models on it.

We do not sell your personal information. We do not share it for advertising. We share it only:

with service providers that run parts of the service for us: our payment processor (PayPal), the AI model providers whose models our software agents use, and our hosting, storage, sign-in and email providers. Each one receives only what its job needs. The current list is available on request.
with professionals or agencies you ask us to involve, and only what you approve;
when the law requires it, or to protect our rights or someone's safety.

4. Tracking and "Do Not Track"

We do not track you across other websites, and we add no analytics or advertising scripts of our own. To show the site, your browser loads fonts from Google Fonts and code libraries from jsDelivr; like any web request, those requests show those services your IP address and browser type. Our host, Vercel, keeps server logs of requests to the site. On the payment step only, your browser loads PayPal's checkout scripts from www.paypal.com. Those scripts may collect information about your device and your activity, including across other websites, under PayPal's own privacy statement. Apart from PayPal on the payment step, we do not let other parties collect personal information about your online activities over time and across different websites through our site. We do not respond to browser "Do Not Track" signals in any special way.

5. Seeing, correcting and deleting your information

Email us at the address below to see the personal information we hold about you, or to correct or delete it. We answer within 10 business days. Some records we must keep: proof of your consent to automatic renewal (for 3 years, or for 1 year after the subscription ends if that is later) and payment records.

6. How long we keep it

We keep account and project information while your subscription runs. For 30 days after it ends we keep your uploads and messages so you can ask for an export; by the end of those 30 days we delete them, and we delete backups within 90 days after the subscription ends. We keep only the improvement material that section 8.3(d) of the Agreement defines, under that section's limits. The records in section 5 are kept for the periods stated there.

7. Security

We use reasonable safeguards, including personal links or one-time-code sign-in, separation between projects, and sign-in logs. We will tell you promptly of any unauthorized access we find.

8. Children

The service is for businesses and is not directed to children under 13. We do not knowingly collect their information.

9. Changes to this policy

When we change this policy in a material way, we email your account owner before the change applies and post the new version here with its new effective date.
