Requests pass through BioHacker's server on Google Cloud, which counts them for daily limits and never stores their content.

It renews automatically unless canceled at least 24 hours before the period ends; manage it in your App Store account settings. -- YOUR DATA -- Your logs are stored on your device; no account needed. Apple Health is read and written only with your permission. Google Firebase Analytics shows which features are used; turn it off anytime in Profile. -- IMPORTANT -- BioHacker is not medical advice. It offers general wellness information and does not diagnose or treat any condition. Talk to a health professional before changing your diet, caffeine intake or medication, especially if you are pregnant or have a health condition.
