Bugs, questions, ideas, or anything about your data: hello@numbertwo.io. You can also send a report from inside the app — Profile → Support — which comes with the app version attached and keeps the thread in one place.
Your account
Deleting your account
Profile → Privacy → Delete my account and data. It is immediate and cannot be undone: your logs, photos, reports, check-ins, sign-in and any share links are all removed at once. Nothing is held for a grace period. If you would rather we did it, email from the address or phone number on the account.
Getting a copy of your data
Profile → Privacy → Get a copy of my data. We assemble it by hand and send it to the email or phone number on your account, normally within 24 hours.
Deleting one log
Open the log from the Journal and choose delete. The photo, its measurements and its report go together.
Changing what you have agreed to
Every switch in Profile → Privacy can be turned off at any time. Turning one off stops anything new; the policy explains what has already happened. See the privacy policy.
Sign-in
You can sign in with Apple, Google, or a phone number. The app does not have a password to reset. If a sign-in method stops working, write to us with the method you used and the email or number on the account.
How it works
- A photo becomes numbers.
- The picture is never read as a picture. Stool is separated from water and paper, and what is left gets measured: Bristol type, colour along several axes, surface texture, how defined the edges are, how many pieces there are, how much of the bowl it occupies. That is a few dozen numbers per log, most of them things you would never register by eye.
- One log says almost nothing.
- A single reading has no context. What carries information is your own baseline over weeks — how much your colour drifts day to day, how tightly your form clusters, what happens to both around travel, antibiotics, or a bad run of sleep. A small change matters because it is a change from you, not because of where it sits on a chart.
- A prediction is really a count.
- The model's only job is deciding what "looks like this" means. It places your log next to the logs it most resembles, and from there the app simply counts: of everyone whose logs landed in this bucket, what did they report over the following days, and how does that compare with the baseline for everyone else? The intelligence is in the arithmetic. Nothing is reasoning about your health.
- Why the app asks you to keep logging.
- Reports only become available once you have a few days behind you, and the counts only get better as more people log more days. That is the honest reason the app asks.
- Why the photo has to be of the bowl.
- Water, paper and lighting are what the app separates out. The framing guide on the camera screen shows where the bowl should sit; a blurry or dark photo is refused before it is uploaded, so you can take another.
What it is not
A diagnosis. Number Two describes and compares, and that is the whole of it. A percentage is a count of other people, never a statement about you. Blood, pain, or any change that is worrying you is a conversation with a clinician, not with an app.
