Privacy Policy
What Signalful collects, why, who helps us, and the choices you have.
Effective October 31, 2026 · Updated November 5, 2026
Signalful (“we”, “us”) publishes executive summaries, analysis, playbooks and highlights at signalful.com and by email. This policy explains what we collect, why, who helps us, and the choices you have. We keep it short and only describe what we actually do.
What we collect
- Your email address, when you subscribe, and your name if you gave it when you signed up. New sign-ups ask for email only.
- Subscription details: your plan (free or paid), trial and renewal dates, and payment status. Card details go straight to our payment processor, Stripe. We never see or store your full card number.
- Email activity: whether you open our emails, which links you click, and whether you rate an email “More like this” or “Less like this.” We use it to see what readers find useful. You can block it by turning off images in your email app.
- How you found us: the page or post you were reading when you subscribed.
- How readers use the site: we use PostHog, a product-analytics service, to understand how people use signalful.com, for example which posts and topics are read, what you search for on the site, whether you mark a post as useful, and where people stop when signing up. Search words are kept to 100 characters, and anything that looks like an email address is left out. For visitors who aren’t signed in, this is anonymous. For signed-in subscribers, it is linked to an internal account ID, not your email address. We use it only to improve Signalful.
- Site visits: cookie-free, aggregate statistics such as page views and referring sites.
- What you send us: comments you post, feedback you leave at the end of a post (your answer, the reason you pick and any note you write), and emails you send to any of our addresses. Your email address goes with your feedback only if you tick “Email me back.”
How we use it
- To send you the newsletters and posts you signed up for, and messages about your account and subscription.
- To process payments, trials and renewals.
- To understand what readers find useful, and improve what we publish and how the site works.
- To answer you when you write to us, and to keep the service secure.
We don’t sell your personal information, and we don’t use it to show you advertising from other companies.
Who helps us
We share information only with the services that run Signalful for us, and only as far as they need it:
- Ghost (Ghost Foundation): hosts the website, manages subscriptions and sends our emails.
- Stripe: processes payments.
- PostHog: site usage analytics.
- Google Workspace: our email inbox, and the private sheet where we keep feedback on posts.
We may also disclose information if the law requires it, or to protect our rights or the safety of others. If Signalful is ever sold or merged, subscriber information would transfer to the new owner under this policy.
Cookies and similar technology
When you sign in, Ghost sets a cookie that keeps you signed in. Stripe, our payment processor, sets cookies on our pages to help prevent fraud and process payments. PostHog keeps an anonymous ID in your browser’s session storage for the length of your visit; it doesn’t set cookies. Where the law requires your consent for analytics, we don’t use it without asking.
Your choices and rights
- Unsubscribe anytime with the link at the bottom of every email.
- Update your email or plan under Account on signalful.com.
- Ask for a copy of your data, a correction, or deletion by writing to info@signalful.com. We’ll reply within 30 days.
Depending on where you live, including the EU, the UK and California, you may have further rights, such as objecting to certain uses or asking us to limit them. Write to us and we’ll handle your request under the law that applies to you.
How long we keep it
We keep your information while you’re subscribed. If you ask us to delete your account, we delete it, except for billing records we must keep by law.
Where it’s stored
Our services may store and process information in the United States and other countries, including Ghost’s servers in the Netherlands.
Children
Signalful is not meant for children under 16, and we don’t knowingly collect their information.
Changes
If we change this policy, we’ll update the date above. If a change is significant, we’ll tell subscribers by email.
