IncludedYour health data belongs to you. Every plan includes full data export, deletion, and our safety framework. We never sell or share your data with third parties.
Yes. The free plan gives you everything you need to run one experiment at a time with basic results. There is no time limit on the free plan — use it for as long as you like.
Plus gives you access to more rigorous experiment styles (Fairer Comparison and Most Reliable), longer durations, full result detail with clarity reasons, cycle phase callouts, and unlimited history. It is designed for women who want deeper insight into what works.
Yes, you can cancel your subscription at any time. You will keep your Plus features until the end of your current billing period. Your data always stays yours — you can export or delete it whenever you like.
Annual billing is a single payment of £37.99 per year, which works out to about £3.17 per month — saving you around 37% compared to paying monthly. You can switch between monthly and annual at any time.
Pro is coming later this year. It will include hand-crafted personal experiments researched and tailored to your specific goals. Sign up to be notified when it launches.
Your data is always yours. If you downgrade from Plus to Free, your existing experiment history and results are preserved — you just cannot start new experiments using Plus-only features. You can always export everything.
