This Privacy Policy explains how Excitonic.com and its associated properties, including the Excitonic Wave newsletter published at wave.excitonic.com (collectively, "Excitonic," "we," "us," or "our"), collect, use, disclose, and protect information about you when you:
By using our site or subscribing to our newsletter, you agree to the collection and use of information in accordance with this policy. If you do not agree, please do not use our properties or subscribe to our newsletter.
Plain-English Summary: We run a website and newsletter about excitonics and photonics. We collect your email if you subscribe. We show ads via Google AdSense. We use Beehiiv to send our newsletter. We do not sell your data. You can opt out at any time.
We collect information in three ways:
A. Information You Provide Directly
B. Automatically Collected Information
C. Information From Third Parties
Excitonic Wave is our weekly newsletter covering excitonics, photonics, and related investment intelligence. It is published and distributed using Beehiiv, Inc., a third-party newsletter platform.
We use Beehiiv (beehiiv.com) to manage Excitonic Wave, including subscriber collection, email delivery, engagement tracking, and monetization features. When you subscribe, your email address and engagement data are processed by Beehiiv on our behalf under a Data Processing Agreement.
Beehiiv's own privacy policy — which governs how Beehiiv Inc. handles platform data — is available at beehiiv.com/privacy.
What Beehiiv collects on our behalf:
Beehiiv's cross-publication tracking: By using Beehiiv, you should be aware that Beehiiv may create and maintain subscriber profiles across multiple publications on its platform, and may track behavioral signals across publications. This is disclosed in Beehiiv's Terms of Use. You can opt out of Beehiiv's platform-level data practices by emailing privacy@beehiiv.com.
Unsubscribing: Every issue of Excitonic Wave contains an unsubscribe link at the bottom. Clicking it immediately removes you from our mailing list. You may also email us at wave.excitonic.com/contact to request removal. We honor all unsubscribe requests within 10 business days as required by the CAN-SPAM Act.
Consent at signup: When you subscribe through our Beehiiv-powered subscribe page, you will be presented with a checkbox requiring you to agree to this Privacy Policy before subscribing. This consent is recorded by Beehiiv with a timestamp and is our lawful basis for sending you email under GDPR.
We use cookies — small data files stored on your device — and similar tracking technologies on excitonic.com and wave.excitonic.com. These fall into four categories:
Managing cookies: You can instruct your browser to refuse all cookies or alert you when a cookie is being sent. However, disabling cookies may affect site functionality. You may also use browser extensions such as uBlock Origin or Privacy Badger to manage third-party tracking.
Do Not Track: Some browsers transmit "Do Not Track" signals. We do not currently respond to Do Not Track signals, as no uniform standard exists. We will update this policy if that changes.
