Privacy
Responsible: LeZo, Switzerland (legal notice: lezo.ch/impressum.html), info@lezo.ch. Swiss data protection law (DSG) applies; for visitors from the EU also the GDPR.
In your browser
Prism Pile needs no account. Your progress (league, collection, coins, statistics, daily task) and your sound setting are saved only in your own browser (local storage, key lezo_ablegespiel, lezo_ablegespiel_fp). On lezo.ch the date of your last game start is also stored (key lezo_zuletzt_prism-pile). These entries are not sent to us. You can delete them at any time by clearing your browser data for lezo.ch.
Anonymous play count
When you start and finish a round, the page may send a short anonymous signal to our own server (game name, event, and whether this is a first, same-day or later visit), plus, as daily totals only, a rough session length class and how many seconds passed until your first move. We store only daily totals: no IP address, no cookie and nothing that identifies you, and no profile is built. Totals are deleted after 24 months.
Error reports. If the game hits a technical error in your browser, it sends a short anonymous error note to our own server (at most 3 per visit): a shortened error message without web or e-mail addresses, the game file name and line number, and your browser family. We use it only to fix bugs and delete these notes after 30 days.
Where you came from. If you open the game through a link with ?von=…, we map it to one of a few fixed labels; the text of the address is never stored. While the tab stays open, this label is kept in your browser's session storage (key lezo_von_prism-pile) so that we can count, as daily totals, which source led to a visit. It disappears when you close the tab.
Server logs
Like every website, our server briefly processes your IP address and browser details to deliver the pages and keep them safe. We use no tracking, no advertising cookies and no third-party scripts on lezo.ch.
Online multiplayer
If you play in an online room, a random seat key for the current room is kept in your browser's session storage (keys starting with lezo_sk_), so that you get your seat back if the connection drops or you reload the page. It contains no personal data and disappears when you close the tab.
Your device connects to a game server run for us by Cloudflare, Inc. (technical service provider, USA and other countries). Cloudflare technically sees your IP address when the connection is set up. We do not read, log or store IP addresses ourselves. Only game moves are passed on to the other player in the room, using a random room code and a random player number. There are no names, no chat and no accounts. Nothing is stored permanently: room data exists only in memory for the duration of the match and is deleted when the room closes.
Because Cloudflare may process data outside Switzerland and the EU/EEA, we rely on appropriate safeguards (Cloudflare's data processing terms with standard contractual clauses and its certification under the Swiss-US / EU-US Data Privacy Framework). You can avoid this by not using online rooms; the game can also be played against the bot.
On game portals
If you play Prism Pile on a game portal, that portal's privacy policy applies there, including its advertising. The game itself only adds the anonymous signals described above, plus the label of the portal as source.
Your rights
You can ask what we store about you and have it corrected or deleted: info@lezo.ch. You may also complain to the Swiss Federal Data Protection and Information Commissioner (FDPIC) or, in the EU, to your local authority.
If you play from the EU/EEA or UK: we process only the technical data described above, on the basis of our legitimate interest in running and securing the game (Art. 6(1)(f) GDPR). The game stores nothing on your device beyond what it needs to work (progress, settings), so no cookie banner is needed. You can object, request access, correction or deletion at info@lezo.ch and complain to your local data protection authority. Data may be processed by Cloudflare outside the EU/Switzerland under standard contractual clauses.
Prism Pile is a non-violent card game. The game itself collects no personal data.
