This page explains what information adikumar.co collects, why, and what you can do about it. It is written for actual humans, not lawyers, and the rules behind it are the Swiss Federal Act on Data Protection (revFADP) and the EU General Data Protection Regulation (GDPR).
Who's responsible
This site is operated as a personal publication by Aditya (Adi) Kumar, based in Switzerland. If you have questions about your data, write to [email protected].
What data is collected, and why
Newsletter subscriptions. When you sign up for the newsletter, your email address is stored so I can send you essays. That's the only purpose. The legal basis is your consent, given when you submit the signup form. You can unsubscribe at any time using the link at the bottom of every email.
Newsletter activity. When you open an email or click a link in it, that activity is logged so I can see which essays are reaching readers. This includes the time you opened the email and your IP address at that moment. The legal basis is legitimate interest in understanding which work resonates. If you'd rather not be tracked this way, reply to any email asking me to disable tracking on your account, or unsubscribe.
Site visits. This site uses no third-party analytics. If analytics are added in the future (likely Umami, a privacy-respecting tool that does not use cookies or track individuals), this section will be updated.
Server logs. Like every web server, the host (MagicPages, with hosting in the European Union (Germany)) keeps short-lived logs of requests, including IP addresses and user agents, for security and operational purposes. These are deleted on a rolling basis within a short period (typically 30 days).
Site preferences. If you toggle dark mode, that preference is stored in your browser's local storage so the site remembers your choice on subsequent visits. This data never leaves your browser.
That's it. There are no advertising trackers, no third-party analytics beyond what's described above, no social media pixels, and no behavioral profiling. Comments are not enabled, so no comment data is collected.
Who your data is shared with
Your email address is shared with Mailgun, the email delivery service that sends out the newsletter on behalf of Ghost (the publishing platform). Mailgun processes the email solely to deliver messages and has no other use for it.
Ghost itself stores subscriber data on infrastructure operated by MagicPages.
Your data is never sold. Your data is never used for advertising. Your data is never shared with third parties for any purpose other than running this publication.
Where your data lives
The site is hosted by MagicPages, with infrastructure in the European Union (Germany). Email delivery runs through Mailgun, which operates in the European Union. If your data crosses borders (for instance, between EU and Switzerland, or between EU and another country), it does so under standard contractual clauses or equivalent transfer mechanisms required by GDPR and revFADP.
Your rights
Under both Swiss and EU law, you have the right to:
- See what data I hold about you
- Correct any of it that's wrong
- Delete it (the right to be forgotten)
- Take it elsewhere in a portable format (the right to data portability)
- Object to processing
- Withdraw consent at any time, where consent was the basis for processing
- Complain to a supervisory authority. In Switzerland, that's the Federal Data Protection and Information Commissioner (edoeb.admin.ch). In the EU, your local data protection authority.
To exercise any of these rights, write to [email protected]. I aim to respond within 30 days.
Cookies
This site uses one technical cookie set by Ghost when someone signs in as a subscriber. That cookie is strictly necessary to keep them signed in and cannot be disabled without breaking the login. There are no advertising cookies, tracking cookies, or third-party cookies.
If you only read essays and never sign in, no cookies are set in your browser.
Changes to this notice
This notice will be updated if data practices change. The date at the top of the page reflects the most recent revision. Material changes will be communicated to newsletter subscribers via email.
