1. What this site does not collect
Brain Train Labs is a set of static browser games. We do not ask for your name, email address or any other personal detail, and there is no login, comment form or newsletter. Nothing you type while playing is sent to us.
2. Data stored in your browser
Some games save your progress locally, using your browser's localStorage. This information never leaves your device and we cannot read it.
| Key | Game | What it holds |
|---|---|---|
brainBreak2048Best |
2048 | Your highest score on this device. |
brainBreak2048State |
2048 | The current board, so a game in progress survives a page reload. |
wordleUnlimitedStreak |
Wordle | Your current win streak. |
braintrainlabs.records |
All four games | Your best result per game, how many games you have finished, and your streak of playing days. This is what fills in the share card. |
The share card (the trophy button) is drawn entirely inside your browser. It turns your own numbers into a picture file you can save or post yourself — we never receive the picture, and no score is uploaded anywhere.
Flow Free and Minesweeper do not save games in progress. The site sets no cookies of its own — see section 4 for the one third-party script we load.
3. Server and CDN logs
Like any website, the computers that deliver these pages record standard request information — IP address, browser user agent, the page requested and the time of the request. This comes from our hosting provider and content delivery network and is used for security, abuse prevention and performance monitoring. We do not use it to build profiles of individual visitors.
4. Sharing buttons
Article pages load a share widget from ShareThis so you can post an article to a social network. The widget is served by ShareThis, not by us. ShareThis may set its own cookies or collect information about the page you shared; we never receive or store that data.
If you would rather it did not load, blocking platform-api.sharethis.com in your browser — with a script or ad blocker — has no effect on the games or the articles.
5. Advertising
This site currently shows no advertising. If ads are added later (for example through Google AdSense), Google and its partners may use cookies or similar technologies to serve and measure those ads, and advertising cookies may be used to personalise them.
If that happens, this page will be updated before ads go live, and you will be able to opt out of personalised advertising through Google Ads Settings or aboutads.info.
6. Children
The games are suitable for a general audience, but this site is not directed at children under 13 and we do not knowingly collect personal information from anyone, of any age. There are no accounts, no messaging features and no user-generated content.
7. Your choices
- To erase everything the games have saved, clear site data for braintrainlabs.com in your browser settings. Your scores and streak will be reset.
- Private or incognito windows discard this data automatically when you close them.
- Because we hold no personal data on our servers, there is nothing for us to export or delete on your behalf.
8. Links to other sites
This page links to Google and aboutads.info for advertising opt-outs. Those sites have their own privacy policies, which we do not control.
9. Changes to this policy
If the way the site handles data changes — for example when advertising is introduced — this page will be updated and the date at the top will change.
