Privacy policy
DealStack is run by Esteban Ibarra. This policy explains what we collect on dealstack.tech, why, and the choices you have. Questions: hello@dealstack.tech.
What we collect
- Your email address, when you ask for the free playbook.
- Booking details, when you book a call: your name, email, the answers you give and the payment. Bookings run on Cal.com and payments on Stripe; we never see your full card number.
- Usage data: pages you visit, buttons you click, how much of the video you watch, your browser and device, a rough location from your IP address, and where you came from (for example an ad or a TikTok post). We use PostHog for this, which can include recordings of how the page was used. Form fields are masked in recordings.
- Advertising data: if you have not opted out, the Meta (Facebook and Instagram) and TikTok pixels record that you visited, watched the video, signed up or booked, so we can measure our ads and show ads to people who visited.
- Cookies and local storage that remember whether you've visited before, whether you signed up, and your choice in the cookie notice.
How we use it
- To send you the playbook and occasional build notes by email (unsubscribe anytime).
- To run the call you booked and follow up about your project.
- To understand which pages, videos and ads work, and to improve the site.
- To show our ads to people who visited the site.
Who we share it with
Only service providers that run the site for us: Cloudflare (hosting), Resend (email), Cal.com and Stripe (booking and payment), PostHog (analytics), Meta and TikTok (advertising). We don't sell your email address or booking details. Sending visit data to Meta and TikTok for advertising may count as "selling" or "sharing" under some US state privacy laws, which is why you can opt out.
Your choices
- Opt out of advertising and analytics: .
- We treat a Global Privacy Control signal from your browser as an opt-out.
- Every email has an unsubscribe option, or reply STOP.
- To see, correct or delete what we have about you, email hello@dealstack.tech. We answer within 30 days.
How long we keep it
Email subscribers are kept until you unsubscribe. Booking records are kept as long as we need them for the project, taxes and accounting. Analytics data is kept for up to a year.
Children
This site is for business owners and is not meant for anyone under 18.
