Privacy policy

What this site doesn’t do

No accounts, sign-in, or payments. The site uses no cookies or browser storage, and has no ad SDKs or tracking cookies. Card swiping and PNG export run entirely in your browser and nothing is sent to us.

Visit statistics

To understand how the site is used and improve it, we use PostHog Cloud EU, a visit statistics service from PostHog Inc. It sets no cookies, uses no browser storage, and receives nothing that identifies you, such as your name, contact details, or account. Visits on different days are never linked together.

Data processed

page address, buttons and links you click and their text, how you arrived (including ad campaign tags), browser and device type, screen size, page load speed, time of visit, IP address

IP address handling

PostHog’s servers mix your IP address and browser details with a value that changes every day, turn the result into a one-way hash, and use it only to count that day’s visitors. The daily value is deleted once that day’s events are processed, and your IP address is not used to look up your location.

Recipient

PostHog Inc. ([email protected])

Location and method

Germany (PostHog Cloud EU, Frankfurt), sent over the internet when you open or click a page

Retention

up to 1 year from collection

How to opt out

a browser’s tracking protection or an ad-blocking extension stops these statistics from being sent. The site works the same either way.
