How we handle your data

Last updated: April 2026. This notice is written for UK readers under the UK GDPR and the Data Protection Act 2018.

What we collect

• Your email address.
• The topics you subscribe to and how often you want to hear from us.
• Delivery records — which issue we sent you, when, and whether it bounced or was marked as spam.

We do not use analytics scripts, tracking pixels, or advertising cookies. We don't collect your name, location, or any device information beyond what your browser sends with a normal request.

Why we collect it

The only reason we have your email is so we can send you the newsletter you signed up for. You confirm your subscription by clicking a link in a confirmation email (double opt-in), and you can leave at any time by clicking Unsubscribe in any issue or by emailing us.

Who we share it with

We use a small set of processors to run the service:

• Supabase — hosts our database (EU region). Your email and subscription choices are stored there.
• Resend — delivers the emails.
• Anthropic — generates paper summaries. We send public paper abstracts, never your email or any subscriber data.
• Valyu — helps us discover papers and articles. We send topic queries only, never subscriber data.
• Vercel— hosts the website you're reading this on.
• GitHub Actions — runs our scheduled background jobs.

We don't sell your data, rent it, or share it with advertisers. If that ever changes, we'll tell you in plain language before it does.

How long we keep it

While you're subscribed, we keep your email and the record of what we've sent you. If you unsubscribe, we mark your row as unsubscribed and delete it completely within 30 days.

Your rights

Under UK GDPR, you can ask us to:

• Show you the data we hold about you.
• Correct anything that's wrong.
• Delete your data (right to erasure).
• Export your data in a portable format.
• Stop using your data (right to object).

Send any of these requests to the contact address in the footer of any issue. We'll respond within 30 days.

If you think we're mishandling your data and we aren't fixing it, you have the right to complain to the UK Information Commissioner's Office (ICO) at ico.org.uk.

Changes to this notice

If we change anything material — new processors, different data, new purposes — we'll update this page and email active subscribers before the change takes effect.
