Nordek is a health log that your own AI assistant can read. This page says what it stores, where, and who can see it. We keep to what is needed for that.

Who is responsible

Nordek is run by Jan Hochbrückner, who is the controller for your data under the GDPR. Contact details are at the end of this page.

What Nordek collects

• Account: your Google account identifier and email address, from Google Sign-In.
• Training: the workout plans and exercises in your library, and every set you log (weight, reps, time or distance, when).
• Nutrition: daily totals for calories, macros and micronutrients, read from Apple Health (last 14 days on each sync).
• Sleep: per night, time asleep, time awake and the core, deep and REM stages when your device records them, plus bedtime and wake time, read from Apple Health (last 14 days on each sync).
• Sauna visits: date, duration and, if you enter them, temperature and a note.
• Profile: answers your AI assistant saves while planning with you, such as birth year, height, sex, experience, goals, available equipment, limitations and free-text notes.
• Body measurements: weight, body fat and waist, when you or your AI assistant log them.

Nordek does not collect advertising identifiers, does not use analytics or crash-reporting services, and does not track you across other apps or sites.

Planned additions

We plan to add more Apple Health data (such as body measurements), more logged activities and medical or body-composition results (such as blood tests and DEXA scans). They will follow the same rules as this page, and this page will be updated before they ship.

Apple Health

Nordek only reads Apple Health data you allow, and never writes to it. Health data is used only to provide your log. It is not used for advertising, and it is not sold or shared with data brokers.

Who can see your data

• You.
• The AI assistant you connect. When you add Nordek as a connector and sign in, that assistant can read (and, for plans, profile and measurements, write) your log. What it does with that data is governed by its provider's own terms.
• Our infrastructure providers. Data is stored in Google Firebase (Firestore, region eur3, EU) and served by a Google Cloud Run service in europe-west1 (Belgium). They process it on our behalf.

We do not sell your data or share it for advertising.

Deleting your Nordek account

Your data is kept until you ask us to delete it. To delete your Nordek account and all its data:

1. Email support@nordek.app with the subject “Delete my Nordek account”, from the email address you sign in to Nordek with.
2. We confirm by email once it is done, within 30 days. Deletion is currently done by hand.

What is deleted: your account and everything listed under “What Nordek collects” above: plans, exercises, logged sets, nutrition, sleep, sauna visits, activities, profile and measurements. Nothing is kept afterwards.

What is not covered:

• Data in Apple Health stays on your phone. Nordek only reads it, so you manage it in the Health app.
• What your AI assistant already read stays in your conversations with it. That is governed by its provider’s terms. To stop it reading new data, remove the Nordek connector in its settings.
• Your deletion email itself, which we keep as a record that you asked.

Your rights

Depending on where you live (for example under the GDPR) you may have the right to access, correct, export or delete your data and to withdraw consent. Email us and we will act on it.
