A surprising number of health apps start sending data to advertising and analytics companies before you have even finished onboarding. It is so common that many teams barely think about it. Add a Facebook SDK. Drop in a pixel. Pipe events into a few ad dashboards. That is the default growth stack now.

We do not think that should be normal for a product that deals with your body, your behavior, and your personal health patterns.

What we removed

We stripped out third-party ad tracking from our app flows. No Facebook SDK. No Google Analytics inside the health experience. No retargeting pixels following you around the internet after you open the app. Your health data is not something we want circulating through external ad systems.

Why this matters

Health data is unusually sensitive. Sleep, workouts, food, stress, symptoms, location patterns, recovery, habits, and biometrics can reveal an enormous amount about someone's life. Even when the raw event being shared looks small, the pattern is often not.

That is why this is not just a technical detail to us. It is a product decision and a trust decision.

What this costs us

Choosing not to use surveillance-style ad tooling has real tradeoffs. It makes attribution harder. It makes funnel optimization slower. It makes targeted ad campaigns less efficient than the standard playbook says they should be.

But we think that is the right trade to make. If a growth tactic depends on passing your private health behavior into third-party systems, then it is not a tactic we want.

What we still collect

We still need to store and process the data that powers Gyroscope itself. That is the point of the product. We use your data to show your dashboards, calculate your scores, power your coach, sync your devices, and save your history for you. But that is very different from handing it off to ad platforms so they can profile you elsewhere.

How you can help

When we choose privacy over ad optimization, word of mouth matters more. Reviews matter more. Referrals matter more. If you want more companies to build this way, supporting the privacy-first ones actually matters.

We chose you over Facebook. We hope more companies do the same.
