Undead Ends is a puzzle game. It works offline; online features (friends, leaderboards, the daily boards, Challenges, Duel, accounts, cloud save) need a connection. We collect as little as we can and never sell personal data.
Undead Ends was previously called DETOUR. Contact: afonso.quinaz@gmail.com.

Ads
Undead Ends shows ads through Google AdMob (rewarded ads you choose to watch, and occasional ads between levels; never with Remove Ads or Undead Ends+). In the EEA, UK and Switzerland you are asked for consent first (Google's consent form). On iOS, Apple's App Tracking Transparency prompt asks whether ads may use your device's advertising identifier; you get the same number of ads either way. Google may collect your device's advertising identifier, advertising data and approximate location (from your IP address) to show and measure ads. Google's use of data: policies.google.com/technologies/partner-sites. You can change your choices in Settings → Ad privacy choices.
Children
Undead Ends is rated for ages 12+ (cartoon zombies, no gore). We do not knowingly collect data from children under 13.
Your rights
Delete your online account at any time in Settings → Account → Delete account: your profile, friends, daily results, ratings, reports, blocks, feedback, cloud save and credentials are deleted immediately. For any other request (access, correction, objection) write to afonso.quinaz@gmail.com.
