What we keep, and who sees it

• The contact form. Your name, email and message, plus your organisation and topic if you fill them in. We also note the page you sent it from, the page that sent you there and your browser, which is how we tell people from spam.
• The chat window. The assistant in the corner of each page keeps what you type, and any name, email or phone number you give it, so a person can follow up. OpenAI's models write its answers.
• Text messages. Your mobile number, the texts and pictures you send us, and the date and wording of your consent. The text message terms cover this in full.
• Visit counts. We count visits with Umami, which runs on our own server. It sets no cookies and does not know who you are. It sees the page, the site that sent you, your browser and your country.
• Client work. If you hire us, we keep the account, project and billing details the work needs.

To answer you, to do the work you hired us for, to send the sign-in codes you ask for and to keep the site running. We do not sell personal information, and we do not use it for advertising.

A few companies run parts of the service for us and see only what their part needs. Vercel hosts the site, Neon holds its database, Google Workspace carries our email, Twilio carries our text messages, OpenAI writes the chat answers and Stripe takes client payments. Beyond them, we share information only when the law requires it.

No mobile information will be shared with third parties or affiliates for marketing or promotional purposes. Text message opt-in data and consent are not shared with any third party. Reply STOP to any text from us and we stop texting you.

Messages, chats and texts stay while they help us work with you. Ask us to delete yours and we will, unless an open contract or the law requires us to keep it.

Email hello@graysandtech.com to see what we hold about you, to correct it or to delete it. California law gives California residents these rights, and we give them to everyone.

The site is not meant for children under 13, and we do not knowingly collect their information.

When this page changes, the date at the top changes with it. Questions go to Gray Sand Technology LLC, San Diego, California, at hello@graysandtech.com.
