My Health Engineer Cookie Policy
Last updated: 2026-10-20
1. Who we are
My Health Engineer ("MHE", "we", "us") is the registered business name of Keith Young, a sole trader at Hillhead, Ardara, Co. Donegal, F94 C640, Ireland. Email support@myhealthengineer.com.
This policy covers what our app stores on your browser or phone, on the web and in our iPhone and Android apps. It also covers the usage counts and error reports the app sends us. Our Privacy Policy covers the rest of your personal data, including your health data, and your rights.
2. What we store and why
We use no advertising cookies and no tracking pixels, and we do not track you across other companies' apps or websites. Our phone apps show the app inside a built-in browser, so the same cookies apply there.
| Purpose | What it does | Do we ask first? | How long |
|---|---|---|---|
| Needed for the service | Keeps you signed in, links a web payment to your account, and tells us you are using our phone app | No | Up to 1 year, or until you sign out |
| Your settings | Remembers choices such as light or dark theme, your last program and the guides you have closed | No | Up to 1 year, or until you clear your browser storage or delete the app |
| Product analytics (PostHog, hosted in the EU) | Counts a few app actions to learn what helps people | Yes. It stays off until you turn it on | Nothing stays on your device |
The law lets us set the first two without asking, because they are strictly needed for the service you asked for. If you block them, you cannot sign in or pay.
In our phone apps, your phone also keeps your reminder times and a record of your store purchases (through RevenueCat). Google or Apple sign-in may keep a record that you signed in.
3. Analytics and error reports
Analytics runs only when you are signed in and have turned it on in your account settings. Turning it on is your consent. Turn it off and it stops at once, on every device. A "Do Not Track" signal from your browser also stops it.
We send PostHog no health values, no page addresses and no advertising ID, and our app tells it not to record your IP address. PostHog keeps no identifier on your device. When it starts, it writes one test value to check your browser and removes it straight away. When you delete your account, we ask PostHog to delete your record.
When the app breaks, Sentry (hosted in Germany) receives an error report with the screen and your device type, but none of your entries. Sentry sets no cookies.
4. Other services
Cloudflare Turnstile checks that a person is signing up by email. Stripe handles web payments. Google, Apple and the app stores run their own sign-in and payment screens. Their own cookie notices apply to what they do.
5. Our website
Our website, myhealthengineer.com, uses necessary cookies only: one remembers your cookie choice for 6 months, and once web checkout opens another remembers your country's price. Analytics (PostHog, hosted in the EU) runs only if you accept it in the cookie banner. It then keeps a random id in a cookie and in your browser's storage to tell new visits from return visits, and records the pages you view, how long you stay, the link that brought you, the sign-up buttons you click, your country and your device. It does not keep your IP address. Advertising cookies run only if you accept advertising, and today the website uses none. Change your choice at any time with Cookie settings at the foot of every page.
6. Your choices
- Turn analytics on or off in your account settings.
- Change the website's cookies with Cookie settings at the foot of any website page.
- Block or delete cookies and stored data in your browser settings. Blocking the cookies the service needs stops you signing in or paying.
- Delete our phone app to remove what it stored.
7. Changes and contact
If we change what the app stores or sends, we update this policy and the date above. If a change needs your consent, we ask in the app first. Questions: support@myhealthengineer.com.
