Consumer health data privacy policy

Version 1.0 · Effective 8 August 2026

Why this is a separate page. Washington State’s My Health My Data Act (RCW 19.373) requires a stand-alone consumer health data privacy policy containing only the information the Act specifies, linked prominently from the homepage. Washington Attorney General guidance is that mixing this content into a general privacy policy, or adding extra material to it, does not satisfy the requirement. Nevada SB 370 (NRS 603A.400–.360) imposes a closely similar obligation. This page is therefore deliberately narrow. Everything else about how we handle data is in our main Privacy Policy.

This policy applies to residents of Washington State and Nevada. We apply the same practices to everyone, everywhere.


1. The central disclosure

[CADENCE LEGAL ENTITY NAME], as a business entity, does not receive, gather, access, retain, share or sell consumer health data.

The precision of that sentence is deliberate, and it matters. RCW 19.373.010 defines “collect” expansively — to “buy, rent, access, retain, receive, acquire, infer, derive, or otherwise process consumer health data in any manner.” Under a definition that broad, the honest description is not a flat “we collect nothing”, but this:

We are therefore not a recipient, holder or seller of your consumer health data, and there is no centralised infrastructure on which it exists.

The disclosures that follow are made in the form the Acts require, and describe (a) the consumer health data the application processes locally under your control, and (b) the small amount of non-health personal data we do receive.


2. Categories of consumer health data collected, and the purpose of collection

2.1 Data generated and stored on your device only

Collected by the app, at your direction, and stored solely in the app’s private storage on your device:

CategoryExamplesPurpose of collectionHow it is used
Bodily functionsBowel movement date and time; Bristol Stool Scale type; completeness of evacuation; straining; urgency; leakage; time spentTo maintain your personal bowel diaryDisplayed to you; summarised in reports you generate
SymptomsAbdominal pain rating; bloating; presence of blood; unusual stool colourTo record symptoms alongside movementsDisplayed to you; used by on-device flag rules
Medications and interventionsMedication names, doses, start and stop dates; laxative use; supplementsTo record what you are taking and when it changedDisplayed to you; used to distinguish spontaneous from aided movements
DietFoods and drinks you type inTo let you look for food–symptom associationsUsed by the on-device correlation engine
Bodily imagesPhotographs, only if you enable this feature, which is off by defaultTo record an observation visuallyDisplayed to you; stored locally
Reproductive and perinatal statusPregnancy mode indicators, if you enable that modeTo adjust the diary for pregnancyDisplayed to you
Data about a person in your careThe categories above, recorded about an infant or another person in caregiver or infancy modeTo let you keep a diary on their behalfDisplayed to you; see the Caregiver Addendum
Derived health informationFrequency, SBM and CSBM rates, typical Bristol range, correlation results, red flagsTo summarise your record and highlight patterns to raise with a clinicianComputed on your device; displayed to you; printed in reports you choose to generate

None of the above is collected by us. All of it is collected by the application onto your device, at your instruction.

2.2 Data we do receive

CategoryPurpose of collectionHow it is used
Email address, if you join the waitlistTo notify you at launch and apply the promised Plus unlockOne email; then deleted per our retention schedule
Email address and message content, if you write to usTo answer your questionSupport response only
Purchase records from Google Play, if you buy PlusTo validate your entitlement, process refunds, and keep required accounting recordsEntitlement and accounting only
Website server log data, including IP addressTo deliver and secure the websiteNot analysed, not profiled

We do not treat any of the above as consumer health data, and we do not infer health status from any of it. We do not, for example, treat the fact that you joined a bowel-health waitlist as an indication that you have a bowel condition, and we do not use it to segment, target, profile or enrich.


3. Categories of sources from which consumer health data is collected

SourceWhat comes from it
You, directlyEvery item in §2.1. All of it is typed, tapped or photographed by you into your own device.
On-device computationDerived measures in §2.1 are calculated by the app from the entries you made. No external source contributes to them.

We collect consumer health data from no other source. Specifically, and for the avoidance of doubt, we do not obtain consumer health data from:


4. Categories of consumer health data that is shared

None.

We share no consumer health data, in any category, with any third party, for any purpose. We have never done so.

This is not a policy commitment layered over a system that could do it. There is no transmission path: the data does not leave your device.

You may of course share your own data yourself — by exporting a CSV, generating a PDF report and giving it to your doctor, or taking a screenshot. When you do, you are the one sharing it, to a recipient you chose, and this policy does not govern what happens to it afterwards.


5. Categories of third parties and specific affiliates with whom consumer health data is shared

None. There are no such third parties and no such affiliates.

For completeness, the following parties process the non-health personal data described in §2.2. They receive no consumer health data:

PartyWhat they receiveRelationship
Cloudflare, Inc.Website hosting and delivery (request logs); waitlist email addresses (stored in Cloudflare KV)Service provider under contract
[EMAIL INBOX PROVIDER]Support correspondenceService provider under contract
Google LLCPlay Store and Play Billing transaction dataIndependent third party under its own policy

No email-sending provider is appointed yet, because no email has ever been sent. One will be named here before the launch email goes out.

Affiliates: We have no affiliates.


6. Sale of consumer health data

We do not sell consumer health data, and we never have.

We have not obtained, and will not seek, the valid authorization that RCW 19.373.100 and NRS 603A require before any such sale. If that position ever changed, the law requires a separate signed authorization from you containing specified terms — it could not be effected by updating this policy, by bundling it into terms of service, or by treating your continued use of the app as agreement.


7. How to exercise your rights

Washington residents have the rights set out in RCW 19.373.030. Nevada residents have equivalent rights under NRS 603A. We extend all of them to everyone, regardless of residence.

7.1 Right to confirm and access

You may ask us to confirm whether we collect, share or sell your consumer health data, and to give you access to it, including a list of all third parties and affiliates with whom we have shared it and an active contact for each.

Our answer will be that we hold none. Your health data is on your device, and you already have complete access to it: open the app, or export the full history as CSV from Settings → Export, free, at any time, without asking us.

7.2 Right to withdraw consent

You may withdraw consent to the collection and sharing of your consumer health data.

In the app, this means turning off any feature you no longer want — photographs, correlation, flagging, or a whole tracking mode — in Settings. Because nothing is shared, there is no sharing consent to withdraw. Withdrawal takes effect immediately and does not require contacting us.

7.3 Right to delete

You may ask us to delete your consumer health data.

7.4 How to submit a request

Email[email protected]
Post[FULL REGISTERED ADDRESS]
Response timeWithin 45 days. We may extend once by a further 45 days where reasonably necessary, and will tell you within the first 45 days if we do, with reasons.
CostFree.
Identity verificationProportionate to the request. For a request about a waitlist address, replying from that address is sufficient. We will not require identity documents where they are not necessary.
Authorised agentsAccepted, with evidence of authority.

7.5 Right to appeal

If we refuse a request, you may appeal by replying to our decision or writing to [email protected] with “Appeal” in the subject line.

We will respond in writing within 45 days, explaining the reasons for our decision.

If we deny your appeal, you may contact:

Washington residents: the My Health My Data Act carries a private right of action under the Consumer Protection Act (RCW 19.86). Nothing in this policy limits that right.

7.6 No retaliation

We will not deny you the app, charge you a different price, provide a different quality of service, or penalise you in any way for exercising any right described here.


8. Geofencing

RCW 19.373.080 makes it unlawful for any person to implement a geofence around an entity that provides in-person health care services, where the geofence is used to identify or track consumers seeking health care services, collect consumer health data, or send consumers notifications, messages or advertisements relating to their consumer health data or health care services. Nevada imposes a materially equivalent prohibition.

This is one of the few provisions of the Act that applies to any person, not only to regulated entities, and it carries the private right of action.

Cadence contains no geofencing capability and collects no location data of any kind — not GPS, not network location, not Bluetooth or Wi-Fi derived location, not IP-derived location, and not location inferred from any other signal. We do not serve advertising of any kind, health-related or otherwise.

10. Changes

We will update this policy if our practices change, and we will not apply a material change retroactively to consumer health data already collected without first obtaining your consent. The version number and effective date above always reflect the current text. Changes are recorded at [/privacy/changelog].
