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
Twin Lanterns needs no account. Your progress (rooms solved, best moves) and your sound setting are saved only in your own browser (local storage, key lezo_twin_lanterns). On lezo.ch the date of your last game start is also stored (key lezo_zuletzt_twin-lanterns), and a count of rounds played so the optional "support us" note appears only now and then (key support_rounds). 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_twin-lanterns) 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.
On game portals
If you play Twin Lanterns on a game portal (for example CrazyGames or Playgama), 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. The version on lezo.ch contains no ads. On portals the game offers optional rewarded ads, shown only if you tap "Watch ad"; the portal's own SDK shows them and is responsible for its data processing. Ads are never required to play.
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.
Twin Lanterns is a non-violent puzzle game and collects no personal data from players.
