Margin. is a free weekly email newsletter. This page says what it collects, why, who else sees it, and how to make it stop. It is short on purpose.

Who is responsible

Margin. is written and published by Rui Bashir in a personal capacity. He decides what is collected and why. Questions, corrections, and deletion requests go to .

What is collected

When you subscribe, through the form on check.ruibashir.com or on margin.ruibashir.com:

• your email address;
• the acquisition source and any UTM tags on the link you arrived through, recorded by beehiiv.

While you are subscribed:

• whether you open an edition, and which links you click.

When you visit the site:

• data from the Meta Pixel: page views, subscription events, your IP address, your browser's user agent, a Meta browser ID stored as _fbp, and, if you arrived from an ad, a click ID stored as _fbc. A hashed version of your email address is sent as well when you subscribe. The section below explains what that means.
• standard server logs, of the kind every web server keeps.

Google Search Console is verified on this domain, which reports in aggregate the search terms and clicks that lead here. Google Analytics is not installed.

Why, and on what basis

Two reasons, and no others. To send you the newsletter you asked for. And to know which channels bring readers, since most currently arrive through Meta ads and I would rather not spend blind.

Your email address is processed to deliver something you requested, and on the consent you gave when you submitted the form. You can withdraw that consent at any time. The pixel measurement rests on a legitimate interest in knowing whether the advertising works. If you would rather it did not run, the cookies section says how to stop it.

Who else sees it

beehiiv hosts the list, sends the emails, and stores subscriber data. It acts as the processor, on my instructions and nobody else's. Its own policy is at beehiiv.com/privacy.

Meta receives the pixel data listed above, for advertising measurement. A hashed email address may also be shared with Meta so that a subscription can be attributed to the ad that produced it. Hashing turns the address into a fixed string of characters before it is sent, so the raw address never leaves this site.

That is the whole list. Nothing is sold. There are no sponsors and no advertising inside the newsletter, and the list is never shared, rented, or swapped.

How long it is kept

Your email address, and the data attached to it, are kept for as long as you are subscribed. When you unsubscribe, you come off the list.

Your rights, and how to use them

You can ask for a copy of what is held about you, correct it, have it deleted, object to how it is used, or withdraw your consent.

Two ways to do that. Every email has a one-click unsubscribe at the bottom, which stops the sending immediately. For anything else, including full deletion, email and say what you want. You will not be asked to justify it.

These requests are honored no matter where you live.

The law, wherever you are

Readers are in the United States, Europe, Switzerland, Morocco, and elsewhere. Rather than work out which regime covers whom, the same rights are extended to everyone: the rights under the EU GDPR, the UK GDPR, the California Privacy Rights Act, and Morocco's Law 09-08. You do not have to live in a covered place to use them.

Cookies

The Meta Pixel sets _fbp in your browser, and _fbc as well if you arrive from an ad. They exist to connect a visit to a subscription.

You can refuse them. Every major browser can block or delete cookies in its settings, and Meta's own ad preferences let you limit how your activity is used for advertising. Neither breaks anything here. The newsletter arrives the same way.

Changes

If any of this changes, the date at the top changes with it.
