Privacy

Cognitive and sensory results can be personal. We collect as little as possible and explain it in plain language.

Without an account

Your answers and results stay in your browser’s local storage on this device. They are not sent to our servers or to advertisers.

With a free account

  • Your email address, so you can sign in with a one-time code. Accounts are run by Supabase.
  • Your test results (scores, the breakdown of each session, the date, and whether you used a keyboard, mouse or touch), so you can see them on any device.

The same email can sign in to our other ChowChow Labs sites, but each site keeps its own data. Deleting your account here removes your results and purchases on this site only.

Payments

Premium is sold by Paddle.com, our reseller and Merchant of Record. Paddle collects your payment details and billing address; we never see your card. We keep a record of what you bought so Premium works when you sign in.

Advertising

Free visitors see one Google AdSense banner. Google may use cookies to show and measure ads; see how Google uses data from sites that use its services. Your answers and results are never shared with Google or any advertiser. Ads are hidden while a test is running, and Premium members see no ads.

Visit statistics

To see which pages help people, we count visits with our own statistics service, run on Cloudflare. It records the page address (never anything you type), the site that sent you, your approximate country and region, your browser and device type, time on the page and a few actions, such as starting or finishing something. A random ID kept in this browser tells new and returning visits apart on this site only; it isn’t linked to your account or shared with our other sites. We never store your IP address. If your browser sends Do Not Track or Global Privacy Control, or you’re in Quebec, no ID is kept. Records are deleted after 13 months. Turn off visit statistics on this site (turn them back on).

Brain and Senses iPhone app

  • No account. The app has no sign-in. Your answers and results are saved only on your iPhone and are never sent to us or to advertisers. Deleting the app deletes them, and you can clear them sooner on a test’s History tab or the My Results tab.
  • Payments for Premium go through Apple’s App Store. Apple handles your payment details and refunds; we never see your card. The App Store tells the app whether you have Premium.
  • Ads. Free users see a Google AdMob banner on some screens, never during a test. AdMob may collect your device’s advertising identifier, approximate location, ad interactions and crash and performance data to show and measure ads. The app asks before allowing tracking (Apple’s App Tracking Transparency), and in the EU, UK and Switzerland Google asks for consent first; you can change that choice under More › Privacy choices for ads. See how Google uses information from apps that use its services. Premium members see no ads, and the ads SDK is not started for them.
  • The app does not use the microphone or camera, and does not use our visit statistics.

What we never collect

  • Medical history or diagnoses
  • Precise location
  • Microphone recordings or camera access (sound is generated on your device)
  • Persistent device fingerprints

Keeping and deleting your data

We keep your account and results until you delete them. You can clear one test’s history on its History tab, or delete your whole account on the Account page. Purchase records may be kept longer where tax law requires it.
