Privacy policy
Treker is a small, account-free website. We do not ask for your name, email or payment details. This page explains what stays in your browser and what our advertising partner may collect.
What we collect
The editor runs in your browser. Your goal, name, amounts and notes are not sent to our server. We do not have user accounts, profiles or a database of saved projects. To understand what works, we count anonymized visits, editor opens and PDF downloads. The visitor id is an irreversible hash of the IP address and browser string; the IP itself is not stored and no cookies are used for statistics.
Advertising and cookies
On the catalog and journal pages we may show ads from an advertising partner. Ads load only after you consent to advertising cookies. You can change your choice at any time from the cookie banner or your browser settings.
Your choices
You can use the editor and download PDFs without accepting advertising cookies. Essential storage remembers your consent choice. For privacy questions, contact us at the address published in the site footer.
