How the analysis works, how the AI fits in, and what we do with your log
A supplement log is intimate. It can include peptides, hormones, and prescription medications, alongside how you actually feel. This page explains, in plain English, what SuppleSense does with that data and how the patterns it surfaces are produced. The full legal versions live in our Privacy Policy and Terms of Use.
The math
SuppleSense surfaces patterns in your own log using a deterministic statistical method, not opaque prediction. For each candidate relationship — a supplement and a subjective rating from your daily check-in — we compute a Spearman rank correlation over the days you have logged, alongside the sample size that underwrites it.
Apple Health and Health Connect measures appear alongside your log today. Correlating a supplement with a biometric is not yet part of the method; this page will say so plainly when it is.
We display a result only when the sample size is at least fourteen days and the false-discovery-controlled p-value clears a calm threshold. The denominator and the confidence interval are shown on every insight. A small sample stays a small sample — we do not present a noisy result as a strong claim.
No AI in the math
Every pattern SuppleSense surfaces is the output of that deterministic method applied to your own log — the same input produces the same finding, every time, and the analysis runs on your device. Today the findings are written with fixed sentence templates, not by a model: no language model reads your log, and none decides what is associated with what.
If we later use a language model to phrase a finding, it will be sent the minimum it needs to write the sentence — the finding, the sample size, the direction — and never your raw log; it will be able to choose how to say "associated with", not what is associated. Our agreements with the model providers we use elsewhere in the product (currently Anthropic, OpenAI, and Google) contractually prohibit them from training their general-purpose models on your inputs or the outputs they generate for you.
You own the log
Your log belongs to you. You can export it as a file at any time and you can delete your account from inside the app. When you delete, we remove your data from production within 30 days and from routine backups within 90.
We do not sell your data. We do not share your log with supplement manufacturers, pharmacies, employers, insurers, or advertising networks. We do not use Apple Health or Health Connect data for marketing, and we do not run cross-context behavioral advertising. Those are commitments we make in the Privacy Policy too, so they hold legally, not just culturally.
Designed for HIPAA, not pretending to be HIPAA
SuppleSense is a consumer wellness tool. It is not a covered entity or business associate under the U.S. Health Insurance Portability and Accountability Act (HIPAA). Records held by your doctor's office are protected by HIPAA; a supplement log you keep here is not — the legal regime is simply different. We think it's more honest to say that plainly than to imply otherwise.
What we do instead: build the system so that, when we are ready to support clinicians and regulated workloads, the controls — encryption in transit and at rest, access logging, data- minimisation defaults, signed service-to-service communication, audit trails — are already in the right places. We are not yet a HIPAA-compliant service, and we will tell you clearly when that changes.
Not medical advice
Statistical observations from your log are observations, not prescriptions. Talk with a qualified clinician before starting, stopping, or changing supplements, peptides, hormones, or prescription medications. If you think you may have a medical emergency, call 911 or your local emergency number immediately.
