We do not use advertising or remarketing trackers on our website. Our site runs on beehiiv, which sets the cookies listed below.

• Essential cookies keep you logged in to STACKED MARKETER PRO, remember your cookie choice and protect the site against bots and abuse. They are needed for the site to work, so they do not need consent.

• Analytics cookies let beehiiv count visits and see which pages and posts are read. They are only set if you click Accept in the cookie banner. You can change your choice at any time with the Customize button in the banner, or by clearing cookies in your browser.

Fonts. We serve our own fonts from our own domain (fonts.stackedmarketer.com), so loading them does not send your data to anyone else. beehiiv's platform also declares the same fonts from Google Fonts. On some pages, mainly ones that contain emoji or uncommon symbols, your browser may therefore fetch a font file from Google, which receives your IP address and browser details. We rely on our legitimate interest in displaying the site correctly, Art. 6(1)(f) GDPR. See Google's privacy policy.

Embedded posts. Some articles embed posts from X (Twitter) or Bluesky. When such a page loads, your browser connects to that platform, which receives your IP address and may set its own cookies. If you are logged in there, the platform can link the visit to your account. Their privacy policies apply: X and Bluesky.

Emails. Our emails contain a tracking pixel and tracked links, so we can see whether an email was opened and which links were clicked. Many email apps let you block images, which also blocks open tracking.

We use the service providers below. They process data on our behalf under data processing agreements and may not use it for their own purposes.

• beehiiv, Inc. (USA): newsletter sending, subscriber database, website hosting, analytics, STACKED MARKETER PRO memberships

• Stripe, Inc. / Stripe Payments Europe (EU / USA): payments for STACKED MARKETER PRO

• PayPal (Europe) S.à r.l. (EU): payments for members who pay by PayPal

• Cloudflare, Inc. (global network, USA): domain and security, our font and course-video hosting, small automations that connect our tools

• Resend (USA): account and system emails

• Campaign Monitor (USA / Australia): newsletter sending, until our move to beehiiv is finished

• Google Ireland Ltd. / Google LLC (EU / USA): spreadsheet where sponsor inquiries are stored; fonts as described above

Sign-up partners. Some readers subscribe through partners such as SparkLoop or Refind, for example from a recommendation in another newsletter. The partner passes us your email address when you choose to subscribe. For what the partner does with your data, its own privacy policy applies.

Sponsors never receive your personal data from us. They get aggregate numbers only, such as total opens and clicks.

Transfers outside the EU. Where a provider processes data in the USA or another country outside the EU, the transfer is covered by the EU-US Data Privacy Framework if the provider is certified, or otherwise by the European Commission's Standard Contractual Clauses.

• Newsletter subscription and email activity: until you unsubscribe, or until we remove you after a long period of not opening or clicking. After that we keep only your email address on a suppression list, so we never email you again by mistake.

• Survey answers: as long as you are subscribed.

• STACKED MARKETER PRO account: as long as your membership runs, plus up to 12 months to handle renewals, refunds and support.

• Invoices and payment records: 7 years, as Austrian tax law requires (§ 132 BAO).

• Sponsor inquiries: like other emails, they stay in our mailbox as message history. If we work together, contracts and invoices follow the 7-year rule.

• Emails you send us, including replies to our newsletters: they stay in our mailbox as our message history with you. We do not delete them on a schedule. Ask us and we will delete them, unless we need to keep them for a legal reason.

• Website server logs: kept by our providers for short periods, usually a few weeks.

Email [email protected] and we will answer within one month, free of charge. You have the right to:

• see the personal data we hold about you and get a copy of it

• have it corrected or deleted

• restrict how we use it, or object to uses based on our legitimate interest

• receive it in a machine-readable format to take elsewhere

• withdraw your consent at any time, for example by unsubscribing. This does not affect anything we did before you withdrew it.

You can also complain to a data protection authority. Ours is the Austrian Datenschutzbehörde, Barichgasse 40-42, 1030 Vienna, [email protected]. You can also contact the authority where you live.

Readers in the United States. We do not sell or share your personal information for cross-context behavioral advertising, and we do not use it to profile you. Depending on your state, you have the right to know what we hold about you, to correct or delete it, and to not be treated differently for using these rights. Send requests to [email protected]. We may ask you to confirm your email address before we act on a request.

Our newsletters and website are for marketing professionals and are not aimed at anyone under 16. We do not knowingly collect data from children. If you think a child has subscribed, email us and we will delete the data.

We update this policy when our services or the law change. The date below shows the latest version. If a change affects something you consented to, we will tell you by email before it applies.
