Privacy Policy

Who we are

The Parkinson's Zone is operated by Dr. med. Julia Reeve, Keurenplein 41 Box A0822, 1069 CD Amsterdam, Netherlands. Email: hello@theparkinsonszone.com.

We are the data controller for any personal data collected through this website and the TPZ app.

What data we collect and why

On this website

If you submit the beta tester application form, we collect your name, email address, country, and the answers you provide in the form. We use this information solely to contact you about the beta programme. We do not add you to any marketing list without your explicit consent.

We do not use cookies, analytics, or tracking of any kind on this website.

In the app

All health data you enter into The Parkinson's Zone — including symptoms, medications, mood scores, journal entries, photos, and voice notes — is stored exclusively on your device using local storage. This data is never transmitted to our servers or to any third party.

If you choose to export a report (for example, to share with your doctor), that export is handled entirely by your device. We never see it.

If you purchase a subscription, payment is processed by Apple (App Store) or Google (Play Store). We receive only a confirmation that a valid subscription exists — never your payment details.

To manage subscriptions we use RevenueCat, a subscription management service. RevenueCat receives an anonymous customer identifier generated on your device and a record of your purchase (which product, when, and whether it is active). It receives no health data, no name, and no email address, and it cannot link the identifier back to you.

Legal basis for processing (GDPR)

For beta tester applications, we process your data on the basis of your consent (GDPR Article 6(1)(a)), given when you submit the form.

For subscription management, we process data on the basis of contract performance (GDPR Article 6(1)(b)).

Because all health data stays on your device and is never transmitted to us, we do not process special category health data (GDPR Article 9) — you remain in full control of it at all times.

Data sharing and third parties

We do not sell your data. We do not share your data with advertisers or data brokers.

Beta application data is received via Formspree (formspree.io), our form processing provider, and forwarded to our email. Formspree's privacy policy applies to their processing: formspree.io/legal/privacy-policy.

Subscription status is processed by RevenueCat, Inc. Their privacy policy applies to that processing: revenuecat.com/privacy.

Subscription transactions are handled by Apple or Google under their respective terms. We have no access to payment information.

How long we keep your data

Beta application data is kept for the duration of the beta programme and deleted within 12 months of the app's public launch, or sooner on your request.

Your in-app health data exists only on your device. Deleting the app removes all of it permanently.

Subscription records held by RevenueCat are kept for as long as your subscription is active, and afterwards only as long as needed for accounting and tax purposes, unless you ask us to delete them sooner.

Deleting your data

Your health data

Everything you enter into TPZ — symptom scores, medications, appointments, journal entries, photos, voice notes, care team details, and reports — is stored only on your device. It is never sent to a server, and we have no copy of it and no access to it.

To delete it, do either of the following:

1. Open TPZ, go to the More tab, then Profile & Settings → My Data → Reset all data; or
2. Uninstall the app from your phone.

Either action removes the data permanently. Because we never held a copy, it cannot be recovered afterwards — by us or by anyone else. If you want to keep a copy first, use the backup export in the app before deleting.

Your subscription record

If you have subscribed, RevenueCat holds an anonymous customer identifier and your purchase history. This contains no health information, no name, and no email address.

To request deletion of that record, email privacy@theparkinsonszone.com and include the Support ID shown in the app under More → Profile & Settings → Subscription → Support ID. That identifier is how we locate your record. We will confirm deletion within 30 days.

Note that deleting your subscription record does not cancel the subscription itself. Cancel that through the App Store or Google Play, under your account's subscription settings.

What we cannot delete

Apple and Google keep their own records of purchases made through their stores, and are required to retain them for tax and accounting purposes. Those records are outside our control. Their respective privacy policies apply.

Beta programme data

If you applied to be a beta tester, email privacy@theparkinsonszone.com and we will delete your application details, including your name and email address, within 30 days.

Your rights

Under GDPR you have the right to:

• Access the personal data we hold about you
• Correct inaccurate data
• Request deletion of your data — see Deleting your data
• Withdraw consent at any time (for beta programme participation)
• Lodge a complaint with your national data protection authority

To exercise any of these rights, email us at privacy@theparkinsonszone.com. We will respond within 30 days.

In the Netherlands, the supervisory authority is the Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl).

Changes to this policy

If we make material changes to this policy, we will update the date at the top of this page. We encourage you to review it periodically.
