Numbers you type into the read-through calculator are processed only in your browser. They are not sent to us. If you copy a result link, the numbers are stored in that link, nowhere else.
To know whether the tool is useful, we count anonymous events (page view, calculation, shared link, sign-up) per day, together with the referring site or campaign tag. We do not use cookies, do not store IP addresses and do not build profiles.
If you join the waitlist, we store your email address and the referring source with our email provider, Kit (Kit.com, ConvertKit LLC, USA), to tell you when early access opens and to send occasional series-market data. Legal basis: your consent (GDPR art. 6(1)(a)). You can unsubscribe with the link in every email or by writing to us; we then stop emailing you and delete your address on request.
The site is hosted by Netlify, Inc. (USA), which processes technical request data to deliver the pages.
You may ask for access, correction or deletion of your data, withdraw consent at any time and complain to your data protection authority. Contact: hello@serieslens.com.
