Privacy Policy
The short version: BLOCK/08 has no accounts, ads or gameplay analytics. Your game progress is kept in your own browser and is not turned into a player profile or copied into an application database. Like any website, the hosting service still receives the requests needed to deliver the page and its files.
Effective date: 19 July 2026
What the game sends
The current game has no sign-up forms, analytics scripts, advertising scripts or social-media embeds. It does not send your puzzle actions, Hint use, scores, progress, local-storage values or a gameplay identifier to BLOCK/08. Your browser does request the static HTML, styles, scripts, images and manifest needed to load the site. Sharing a result only uses your browser's share or clipboard feature after you choose Share.
What is stored on your device
To remember your game between visits, BLOCK/08 uses your browser's local storage. This data is written and read by the game in your browser, on your device. The current game does not upload these values. The stored values include:
- Classic progress and results, including the archived legacy star record, content-versioned results, optional Mastery and your active-time personal best.
- Daily puzzle history: which days you completed and your current streak.
- Best score in Rush mode, and unlocked achievements.
- Recovery state for Learn, an interrupted attempt and storage migration.
- Preferences: sound on or off, light or dark theme, interface language.
You can erase all of this at any time by clearing site data for this website in your browser settings. Note that doing so resets your progress, since no copy exists anywhere else.
Cookies
The BLOCK/08 game code does not create or read cookies. Depending on the protection settings active for the hosted site, Cloudflare may use necessary cookies or similar technology to deliver or secure requests; those practices are covered by Cloudflare's policy linked below, not by the game's local progress store.
Children
BLOCK/08 does not ask players for a name, email address, age or other account information. There is no chat, user-generated content or form for submitting personal information through the game. Hosting requests are still handled as described below.
Hosting and third parties
The game loads no third-party scripts, ads, fonts, embeds or analytics. The release configuration targets Cloudflare Workers Static Assets for static hosting. Cloudflare processes ordinary request metadata needed to deliver and protect the site, which can include an IP address, traffic-routing data, system information and request records. BLOCK/08 does not copy that metadata into a gameplay profile or analytics database. Cloudflare's own practices are described in its Privacy Policy. If BLOCK/08 later introduces measurement, advertising, accounts or another processor, this policy will be updated before that collection is enabled.
