Game progress is stored in your browser’s local storage, on your own device. It is never uploaded. Clearing browser data deletes it, so use Export save code if you want to keep a copy or move to another device.

The game reports a small number of anonymous events so I can see how many people reach each stage and whether anyone comes back the next day. An event contains what happened, how many days since this browser first opened the game, a broad day-range cohort, which visit number this is, how many times the specimen has gone extinct and the current game-build label. Relevant events can also include a mutation, endless-stage or Strain choice; mutation or endless-stage number; genome recovered; seconds into the current life; or seconds spent away. Each number has a strict maximum before it is stored. Cloudflare adds a two-letter country code so regional totals can be compared.

These events contain no visitor identifier. No cookie, random ID, fingerprint or IP address is written to the game’s analytics dataset. Cloudflare sees an IP address transiently to serve the page and derive the country code, as any web host must.

The site also uses Plausible Analytics to count page views, visits and broad traffic trends. It receives the page path, referring site, campaign parameters, engagement time, browser, operating system, device type and approximate country, region and city. Ordinary query parameters are discarded. It also records six named conversion events: opening the jar from a public page, the first feed, first organ, first mutation, first extinction and a successfully completed specimen share. No tap totals, creature names, save data or mutation choices are sent to Plausible.

Plausible sets no cookies and creates no persistent identifier. It uses the IP address and browser user agent transiently to make a website-specific daily identifier; the salt is replaced every 24 hours and the raw IP address and full user agent are not stored. This cannot connect visits across different days, devices or websites. The aggregate data is processed and stored in the EU. See the Plausible data policy.

The Anonymous counts switch is at the bottom of the Records panel. Turning it off stops both the game events and Plausible page counting immediately. The preference stays in this browser even if the game save is wiped. Nothing else about the game changes.

After you make some progress, the game asks the browser to hold on to its saved data using the standard persistent-storage permission. Browsers can otherwise clear local data when space runs short. Your browser decides whether to agree, and Records shows its answer. The request sends nothing anywhere.

The gameplay code remains self-contained and has no external fonts or embeds. Its first-party progress events go to this domain. The optional Plausible script is loaded from plausible.io and sends the aggregate site-traffic measurement described above to Plausible. If that script is blocked or unavailable, the site and game continue to work normally.

None. The game sets no cookies and runs no advertising.

No personal data is collected from anyone, including children.
