Privacy Policy

Effective June 15, 2026

Dalton Health ("Dalton," "we," "us") operates the website dalton.health and the Dalton Sync iOS app. This policy covers both. The first part explains what we collect when you request access through the website. The second explains how Dalton Sync handles the health data you choose to bring into Dalton. Where the two differ, each part says so.

Part 1 — The dalton.health website

What we collect

When you submit the access request form, we collect:

• Your email address
• The professional segment you selected (e.g., Military / Special Forces, Emergency Services)
• Your approximate country, derived from your IP address at the time of submission
• The date and time of your submission

We do not store your full IP address beyond the initial request.

Why we collect it

We use this data for one purpose: to evaluate access requests and contact you about Dalton, our human performance platform. We will not sell, rent, or share your data with third parties for marketing purposes.

Where your data is stored

Your submission is stored in Cloudflare KV, a key-value data store operated by Cloudflare, Inc. Cloudflare maintains data centers globally and processes data in accordance with their privacy commitments and applicable data protection regulations. When you submit the form, we also send ourselves an email notification through MailChannels so we can review your request promptly.

How long we keep it

We retain your submission data for as long as it is needed to evaluate and respond to your access request. If you would like your data deleted sooner, contact us and we will remove it within 30 days.

Cookies

The main dalton.health site does not set any cookies. We load Google Fonts for typography, which may set its own cookies according to Google's privacy policy. We do not use analytics, tracking pixels, or advertising cookies of any kind.

Part 2 — The Dalton Sync app

Dalton Sync is a companion app for Dalton. It reads health and fitness data from Apple Health on your iPhone and forwards it to your personal Dalton cell, where your readiness intelligence is built. Dalton is invite-only. If you have not been invited, the app cannot pair and reads nothing.

What the app reads

With your explicit permission, Dalton Sync reads the following from Apple Health, and nothing else:

• Heart rate, resting heart rate, and heart rate variability
• Sleep analysis
• Respiratory rate and body temperature
• VO2 max and active energy
• Steps and workouts

The reads are one-directional. Dalton Sync never writes to Apple Health and never modifies your records there.

The app uses your camera once, to scan the pairing code shown on app.dalton.health. No photos or video are taken, stored, or transmitted. The camera is used only to read that single code.

Where your data goes

Paired data is sent to your own Dalton cell, a dedicated, isolated environment provisioned for your account. Transmission happens over HTTPS with TLS on every hop, so your data is encrypted while it moves across the network.

Your data is stored in your cell so that Dalton can build your readiness model from it. You own that record. You can review it, and you can delete your data or revoke the app's access at any time from app.dalton.health.

What we do not do

• We do not use your health data for advertising or marketing.
• We do not sell your health data, and we never will.
• We do not share your health data with third parties for their own purposes.
• We do not send your health data to third-party analytics services.

Health data read through Apple Health is used for one purpose only: to build the readiness intelligence you signed up for.

Your control over app data

You decide which Apple Health categories Dalton Sync may read, and you can change those permissions in the iOS Health app at any time. Revoking a permission stops new data of that type from flowing. Deleting your account or your data at app.dalton.health removes it from your cell.

Children

Dalton Sync is not directed to children and is not intended for anyone under 18.

Applies to both

Your rights

Under the GDPR and similar data protection laws, you have the right to:

• Request a copy of the data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Withdraw your consent at any time

To exercise any of these rights, email us at privacy@dalton.health.

Changes to this policy

If we make material changes to this policy, we will update the effective date at the top of this page.
