What we collect and why

Game progress on your device. Your notes, solved cases, strikes, record, streak and settings are saved in your browser's local storage (all entries start with lieup.). This data never leaves your device and is never sent to us. It exists only so the game can remember where you are. You can delete it at any time by clearing this site's data in your browser settings.

Server logs when you visit. The website is delivered by Cloudflare. Like every web server, it receives technical data that your browser sends with each request: your IP address, the date and time, the page or file requested, your browser and operating system (user agent) and the referring page. Cloudflare uses this data to deliver the site, to protect it against attacks and abuse, and to give us aggregated traffic statistics (for example, the number of visits per day or per country). We do not receive or store individual IP addresses, and we do not use this data to identify you.

Emails you send us. If you write to [email protected], Cloudflare Email Routing forwards your message to our mailbox, which is hosted by Google (Gmail). We use your email address and message only to answer you.

Sharing your result. The share text (for example, "lie.up · Case file #25") is created in your browser and contains no names and no personal data. If you share it, it goes through the app you choose, under that app's privacy policy.

No third-party content. The game and its font are served from our own domain. We do not load Google Fonts, social media widgets, analytics scripts or advertising code.

Legal bases (GDPR)

• Saving your game progress in local storage is strictly necessary to provide the game you asked for (Section 25 (2) no. 2 of the German Telecommunications Digital Services Data Protection Act, TDDDG).
• Server logs and aggregated statistics are based on our legitimate interest in running a secure, working website and understanding how much it is used (Art. 6 (1) (f) GDPR).
• Handling your emails is based on our legitimate interest in answering your request (Art. 6 (1) (f) GDPR).

Cookies

lie.up does not set cookies. It only uses your browser's local storage, as described above, so the game can work. That is why there is no cookie banner.

Who we share data with

• Cloudflare, Inc. (101 Townsend St, San Francisco, CA 94107, USA) hosts the website, provides DNS and forwards emails. Cloudflare acts as our processor under its data processing addendum.
• Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland) hosts the mailbox (Gmail) that receives forwarded emails.

We do not sell or rent personal data, and we do not share it with anyone else unless the law requires us to.

Advertising

lie.up currently shows no advertising. If that changes, we will update this policy before any ads appear and ask for your consent where the law requires it.

International transfers

Cloudflare and Google may process data in the United States. Both companies are certified under the EU-U.S. Data Privacy Framework, for which the European Commission has adopted an adequacy decision. Where needed, they also use the European Commission's Standard Contractual Clauses.

How long we keep it

• Game progress stays on your device until you delete it.
• Cloudflare keeps server logs only for a limited period; we only see aggregated numbers.
• Emails are deleted once your request is handled, unless we have to keep them for legal reasons.

Your rights

Under the GDPR you have the right to access the personal data we hold about you, to have it corrected or deleted, to restrict its processing, to data portability, and to object to processing based on legitimate interests (Art. 15 to 21 GDPR). To use these rights, write to [email protected].

You also have the right to lodge a complaint with a data protection supervisory authority, in particular in the EU member state where you live, work, or where you think the infringement happened (Art. 77 GDPR).

Children

lie.up has no accounts and asks for no personal information, so it does not knowingly collect data from children.

Changes to this policy

We will update this page when the website or the law changes. The date at the top shows the latest version.
