Privacy, in plain words.

This site collects as little as it can: your email address if you ask for the free page or buy the book, and anonymous page counts. No advertising trackers. No cookies that follow you.

Who is responsible

The Quiet Jar is run by a sole trader based in Poland, who is the data controller under the GDPR. Full business details are available on request. Write to contact@thequietjar.com for anything on this page.

Who processes it on my behalf

Nobody else. The list is never sold, rented or shared.

Cookies

The site sets none. The checkout window from Lemon Squeezy sets what it needs to complete a payment; their policy covers that.

Your rights

You can ask to see, correct, export or delete what I hold about you, or object to its use. Email contact@thequietjar.com; I answer within a month, usually much sooner. You can also complain to your data-protection authority (in Poland: UODO, uodo.gov.pl).

Children

The site is not aimed at anyone under 16 and I don't knowingly collect their data.

Changes

If this page changes in a way that matters, the list gets one email saying so. The date at the top tells you when it last changed.
