Privacy
Short version: we do not track you. Here is the detail.
What the site itself collects
The code of this site includes no analytics, no advertising, no social-media widgets and no scripts from other companies. Fonts and images are served from this site. The site sets no cookies.
Your scrolls: stored in your browser only
The game saves your progress using your browser's localStorage, under the key yl_scrolls_v1. It holds the scrolls you unsealed, your best score for each level, the last ten scrolls the game drew, and the level and category you chose last. This data never leaves your device and we cannot see it. If your browser blocks storage, the game still works while the tab stays open and tells you so.
To delete it: use the button below, the "Clear my scrolls" button on the album, or clear the site's data in your browser settings.
The contact form
When you send the form, the script on our server receives your name, email address, topic and message, and emails them to contato@woowsai.com. The script does not write them to a database or a file. We keep the email only as long as we need it to answer you and to document corrections, and we delete it on request.
To limit abuse, the script allows three messages per hour from one connection. For that it keeps a small file named after a one-way hash (SHA-256) of your IP address, containing the times of your recent attempts. A hash is not a name, but it can still identify a connection, so we treat it as personal data. The files are removed after at most two hours.
Hosting and networks
This site is delivered through Cloudflare, a network that sits in front of our hosting provider. Cloudflare and the hosting provider process requests (for example the IP address, the time and the page asked for) to deliver and protect the site, under their own policies, and may keep standard server logs. We have not added any analytics, advertising or tracking of our own, and we do not receive those logs as individual records. When we checked the live site on November 9, 2026, no cookies were set. If we learn that a provider adds measurement or sets cookies, we will describe it here.
Links to other sites
Scrolls link to the sources we used. Those sites have their own privacy policies.
Children
The site is written for general audiences, including students and teachers, and is not directed at children under 13. We do not knowingly collect information from children.
