Privacy Policy

Last updated: October 17, 2026

AIpster ("we," "us," or "our") operates the website https://aipster.com. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.

AIpster is an independent, informal think tank and blog focused on artificial intelligence. We are not a registered company. For any privacy-related questions, contact us at [email protected].

1. Data We Collect

1.1 Membership and Newsletter

When you sign up as a member or subscribe to our newsletter, we collect:

• Email address (required)
• Name (if provided)

This data is stored in our self-hosted Ghost CMS database. We use it solely to manage your membership and send you newsletters you opted into.

Legal basis: Consent — you actively choose to sign up.

Email engagement: Our emails contain a small image and tracked links, so we can tell whether an email was opened and which links were clicked. For each of these events we record the date and time, a shortened IP address (the last part is removed) and your browser or device type. We also record when you unsubscribe. Open counts are approximate, because some email apps load images automatically.

Legal basis for email engagement: Our legitimate interest in understanding which content is useful and in keeping our email list healthy. You can object at any time by unsubscribing.

1.2 Analytics (Matomo)

We use Matomo, a self-hosted, privacy-focused analytics platform operated by Inteligencja Tecnologia (part of the same group as AIpster), to understand how visitors use our site. Matomo collects:

• Pages visited and time spent
• Referring website
• Browser type and screen resolution
• Approximate geographic location (country/region level)

For Matomo, IP addresses are anonymized before storage and no Matomo data is sent to third parties. All Matomo data is stored on servers controlled by Inteligencja Tecnologia.

Legal basis: Legitimate interest in understanding site usage to improve content.

1.3 Analytics & Advertising (Google Analytics 4)

We also use Google Analytics 4 (GA4), a web analytics service provided by Google LLC ("Google"), a third party located in the United States. GA4 uses cookies and similar identifiers to collect:

• Pages and screens viewed, events, and interactions on the site
• Referring website and campaign information
• Device, browser, and operating system information
• Approximate geographic location derived from your IP address (Google does not log or store your full IP address in GA4 by default)

This data is processed by Google on its servers and is subject to Google's Privacy Policy. We use GA4 to understand how visitors use our site and, going forward, to measure and run advertising campaigns that promote AIpster content — for example, building audiences for Google Ads remarketing so we can reach people who have shown interest in our work. These advertising features may involve advertising cookies and sharing data with Google for advertising measurement and audience building.

Legal basis: Your consent and/or our legitimate interest in measuring site usage and promoting our content. You can opt out at any time — see Section 5, Your Rights.

1.4 Cookies

We use essential, analytics, and (for Google Analytics / advertising features) third-party cookies:

If we enable Google advertising features, Google may set additional advertising cookies (for example on Google domains) used for remarketing and ad measurement. We do not sell your personal data, and we do not allow advertising networks other than Google to track you on our site.

2. How We Use Your Data

• Deliver newsletters you subscribed to
• Manage your membership (login, preferences)
• Analyze site usage to improve content and user experience
• Measure and run advertising that promotes AIpster content, including building audiences for Google Ads remarketing via Google Analytics 4
• Respond to inquiries sent to our contact email
• Understand which emails are read and adjust how often we write to you: if you have not opened or clicked our emails for a long time, we may send you the Daily less often, ask whether you still want it, and eventually stop sending it to you. This does not delete your account, and you keep receiving our regular newsletter.

We do not engage in automated decision-making that produces legal or similarly significant effects about you.

3. Data Sharing

We do not sell or rent your personal data.

Your data may be disclosed or shared:

• With Inteligencja Tecnologia, which hosts our infrastructure (self-hosted analytics, email delivery) under the same operational group
• With Google LLC, which processes site usage and advertising data through Google Analytics 4 and related advertising products. Google acts under its own Privacy Policy and data processing terms; data may be transferred to and processed in the United States
• If required by law or court order
• Cloudflare, which delivers and protects our website. Website traffic, including the links in our emails, passes through its network.

4. Data Retention

• Membership data is retained as long as your account is active. You can delete your account at any time.
• Newsletter subscriptions are retained until you unsubscribe.
• Matomo analytics data is anonymized and retained for up to 26 months, then automatically purged.
• Google Analytics 4 data is retained according to Google's settings for our property (user- and event-level data retained for up to 14 months), after which it is automatically deleted by Google. Aggregated reports may be retained longer.
• Email engagement records (opens, clicks and unsubscribes) are kept while you are subscribed. The shortened IP address and browser details in these records are deleted after 180 days.

5. Your Rights

You have the right to:

• Access the personal data we hold about you
• Correct inaccurate data
• Delete your account and associated data
• Withdraw consent for newsletter emails at any time (via the unsubscribe link in every email, which stops all AIpster emails)
• Opt out of analytics and advertising tracking
• Object to the measurement of email opens and clicks (unsubscribing stops it)

To opt out of Matomo analytics, you can enable your browser's "Do Not Track" setting — Matomo honors it by default.

To opt out of Google Analytics 4, install the Google Analytics Opt-out Browser Add-on, block analytics/advertising cookies in your browser, or use a content blocker. Note that GA4 does not rely on the browser "Do Not Track" signal. You can also manage Google's use of your data for advertising at Google My Ad Center.

If you are in Brazil, the LGPD also gives you the right to confirm that we process your data, to receive a copy of it in a portable format, to be told with whom we share it, and to revoke your consent. Contact us to exercise these rights.

Unsubscribing: the unsubscribe link in any AIpster email stops all AIpster emails: the newsletter and the Daily. It also stops the measurement of opens and clicks for your address.

To exercise any of these rights, contact us at [email protected].

6. Security

We take reasonable measures to protect your data:

• All traffic is encrypted via HTTPS
• Our infrastructure is self-hosted with restricted access
• Passwords are never stored in plain text (Ghost uses secure hashing)

7. Local AI Playground

The Local AI Playground (available at aipster.com/ai-playground) runs AI models entirely inside your browser using your device’s GPU via WebGPU. All inference happens locally on your machine.

We do not collect, transmit, store, or have access to any data you input into the Playground, any output the models generate, or any aspect of your interaction with the models. No prompts, responses, or usage telemetry leave your device. The model weights are downloaded directly to your browser cache and all processing occurs client-side.

Standard analytics (Matomo and Google Analytics 4, as described above) apply to the Playground page itself — that is, we can see that someone visited the page — but they have no visibility into what you do inside the Playground application.

8. Third-Party Links

Our blog posts may contain links to external websites. We are not responsible for the privacy practices of those sites. We encourage you to read their privacy policies.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the site after changes constitutes acceptance.
