Privacy Policy

Last updated: October 28, 2026

BrassTacks ("we", "us") runs mybrasstacks.com, a research tool that finds business opportunities in problems people describe publicly. This policy explains what data we collect, how we use it, and how to ask us to delete it.

What we collect

From you, directly. If you email us, we keep your email address and anything you choose to tell us. If you join our waitlist, see "Waitlist" below. Our web server keeps standard logs (IP address, browser type, pages requested, time) for security and troubleshooting.

Public content from other platforms. We collect publicly available posts from platforms such as X, Threads, Bluesky and Hacker News, through their official APIs and under their developer terms. We search by keyword for posts about business problems, for example people asking whether a tool exists or looking for an alternative to one. For each post we store:

• the post's ID, link and timestamp
• the minimum text needed to analyze it
• the structured signal we extract from it (the problem described, who has it, any workaround mentioned)

We don't collect private messages, follower lists or non-public content, and we don't build profiles of individual people.

Waitlist

What we store. When you join the waitlist we store your email address, whether you ticked the Idea of the Day box (and which ideas we emailed you), when you signed up and confirmed, which page you signed up on, and which version of this policy you agreed to. We don't store your IP address: we keep only a salted, one-way hash of it, and the salt changes every day, so it can't be traced back to you or linked across days. We use it only to stop the same connection from signing up too often.

Why. To contact you about BrassTacks: when it opens, and anything important before then. We send the free Idea of the Day email only if you ticked that box; every one has a one-click unsubscribe.

Double opt-in. After you sign up we send one email with a confirmation link. You're only on the list once you click it. If you don't confirm within 30 days, we delete your signup.

Unsubscribing and deletion. Every email we send has an unsubscribe link. On that page you can also delete your data, which removes your signup immediately. You can also ask at hi@mybrasstacks.com, and we'll delete it within 30 days.

How we use it

• We use AI language models to classify posts and decide whether each one describes a real business problem.
• We publish only our own written analysis of an opportunity, with a link back to the original public post where relevant.
• We never republish, sell or share raw posts or datasets.
• We never use content collected from other platforms to train or fine-tune AI models.
• We don't analyze or infer sensitive characteristics such as health, politics or religion, and we don't track or monitor individuals.
• We use your email only to send you what you signed up for and to reply to you.

Who processes data for us

We use a small number of service providers to run BrassTacks: a cloud hosting provider for our servers and database, AI model providers (accessed through OpenRouter) to classify and analyze content, and an email provider to send and receive mail. They process data only to provide those services to us.

How long we keep it

We keep public content only as long as we need it for research. When a post is deleted or made private on its original platform, we remove our stored copy of its text as the platform's terms require, and we keep only a record that it existed and was removed. We keep your email until you unsubscribe or ask us to delete it. Server logs are kept for up to 90 days.

Deleting your data

You can ask us to delete any data we hold about you, including your email address or content you posted publicly that we collected. Email hi@mybrasstacks.com with the subject "Data deletion request", and include your email address or the platform and username the content was posted under. We'll confirm and complete the deletion within 30 days. How data deletion works.

You can also unsubscribe from any email we send using the link in that email.

Cookies

This site doesn't use tracking or advertising cookies. It loads fonts from Google Fonts, which receives your IP address when the fonts load.

Children

BrassTacks is not intended for anyone under 16, and we don't knowingly collect data from them.

Changes

If we change this policy, we'll update the date at the top of this page. For significant changes, we'll also notify people on our email list.
