Privacy Policy

This policy explains how Submilli handles information when you use submilli.ai (the “Site”). It applies to the Site, not to the separately licensed open-source software.

Information we handle

When you visit the Site, our hosting provider and service providers may process technical information such as your IP address, browser and device information, pages requested, referring page, and the date and time of your visit.

If website analytics is configured, we use PostHog to receive limited information about Site use, including page views and selected link or contact-option interactions. The Site is configured to avoid analytics autocapture and to remove query strings and fragments from URLs sent with those events. Session replay may be enabled on the production Site; if it is, it can record page content, interactions, and information entered into fields.

If you email hello@submilli.ai, we receive the information you include in your message and use it to respond. If you choose “Book a call,” you leave the Site for Google Calendar. We use booking details, such as your name, email address, appointment time, and answers you provide, to arrange and follow up on the meeting. Where our booking integration is enabled, Google Apps Script sends the booking contact email address to Attio, our customer relationship manager. It sends appointment activity, including the contact email address and booking status and time, to PostHog.

The Site’s interactive playground uses bundled sample data in your browser. It does not send playground selections, sample content, or API keys to external services.

How we use information

We use information to operate and secure the Site, understand and improve its use, respond to messages, and arrange requested meetings. We do not sell personal information.

Cookies and browser storage

The Site uses browser storage for analytics attribution and preferences. Visiting submilli.ai/?analytics=off stores an analytics opt-out in local storage and sets the submilli_analytics_consent cookie for up to one year. This stops future Site analytics and replay in that browser; it does not delete information already collected. When analytics is active, PostHog may also use browser storage. You can clear or block cookies and local storage in your browser; doing so can remove your opt-out preference.

Service providers and external services

We use Render to host the Site, Google Fonts to load its typefaces, and, when configured, PostHog for analytics. Google Calendar provides the booking page linked from the Site. Where the connected booking integration is enabled, it also uses Google Apps Script and Attio. These providers process information under their own terms and privacy policies. Links to other websites and services are governed by the policies of those services.

Retention

We retain information for as long as reasonably needed for the purposes described here, including responding to you, operating the Site, and meeting legal obligations. Retention by service providers is subject to their own practices and settings.

Your choices and requests

You can use the analytics opt-out above, manage browser storage through your browser, and choose not to use the email or booking options. Depending on applicable law, you may have rights to request access to, correction of, or deletion of personal information we hold about you. To make a request or ask a privacy question, email hello@submilli.ai.

Children

The Site is not directed to children, and we do not knowingly collect personal information from children. If you believe a child has provided personal information to us, contact us at hello@submilli.ai.

Changes to this policy

We may update this policy from time to time. We will post the updated version here and change the “Last updated” date.
