Solo play
Chainle stores solo puzzle progress, scores, and personal bests on your device. The iPhone app does not require an account, and solo play works offline. The app includes no advertising or analytics SDK.
Chain Lock and the leaderboard
When you start a ranked run, Chainle stores a random player identifier, start time, submitted guesses, checks used, and solve time on the ranked puzzle service. The service uses these details to validate the run and rank results. A cookie retains the player identifier on your device for up to one year.
Publishing a result is optional. If you publish, other players can see your rank, time, and checks used. The iPhone app shows system-assigned player labels. On the website, a result may also show a nickname chosen by the player. Choose a nickname that does not identify you. When you share a result through the iOS share sheet, you choose who receives it.
Website analytics and hosting
On the game website, Chainle uses Umami and Google Analytics to understand visits. The site can send information such as the page, referring site, language, and campaign tags. It skips this analytics code when the browser signals Do Not Track or Global Privacy Control. Cloudflare hosts the site and processes network requests to deliver and protect it.
Retention and deletion requests
Ranked records are stored by puzzle date and do not expire automatically. To request removal, email support with the puzzle date and enough information to identify the entry, such as its rank and solve time. We may ask for more details to verify the request. You can avoid ranked data collection by playing the offline modes. You can clear locally stored game data by deleting the app or clearing the site data in your browser.
