Privacy Policy

PEAKNESS™ · Last updated: September 30, 2026

This policy explains what PEAKNESS collects when you use the app and this website, why, and what your rights are. PEAKNESS is run by BR Works in the Netherlands, which is responsible for your data. Contact: im@peakness.app.

1. What we collect

  • Account: your email address, and a display name if you give one.
  • Training: your profile and preferences (goals, equipment, sports, benchmarks), your workouts and logged sets, workouts you paste in or edit, and your progress.
  • Health details you choose to give: injuries and whether a professional has cleared you to train, height, weight, date of birth, gender, and your daily check-in (sleep, energy, soreness). All optional, and you can change them in Training Preferences (for date of birth, only your age).
  • What you type or say to your coach. Workout requests are kept for 12 months; voice is turned into text and not kept.
  • If you turn on cycle tracking or give your life stage: when your last period started, your usual cycle length, contraception if you answer that, the days you mark as a period, and the stage itself. These stay on your phone — see section 4.
  • Feedback you send from the app.
  • If you turn on notifications: your device's notification token, so reminders and coach nudges can reach your phone.
  • Usage and diagnostics: how you use the app, linked to your account, an app installation identifier, crash and performance reports, and records of how your workouts were made.
  • Your subscription status, and whether you opted in to marketing email.
  • On this website: your email address if you joined the waitlist before launch.

We don't collect your location or contacts, and we don't track you across other apps or websites.

2. Why we use it

  • To run your account, make your workouts and manage your subscription: this is needed to provide the service to you.
  • To use your health details in your workouts, and to email you news and offers if you opted in: based on your consent. You can withdraw it at any time by deleting your account in Settings → Privacy & account; every marketing email has an unsubscribe link. Cycle tracking and life stage each ask for their own consent, and you can switch either off at any time in Settings → Training Preferences.
  • To keep the app working and improve it, from usage data, crash reports and what members ask for: based on our legitimate interest. You can object by emailing us.

We never sell your data.

3. Who receives it

PEAKNESS builds your plan with its own training system and uses AI providers where needed. They receive your profile, health details and what you tell your coach, and never use it to train their models. We also use service providers for hosting, analytics (in the EU), crash reporting, notification delivery, subscriptions and email. Exercise videos and images load straight to your device from the services that host them, which see your IP address.

4. Cycle and life stage

Both are optional and off until you turn them on, and neither is needed to use PEAKNESS. Cycle tracking and telling us your life stage (pregnant, postpartum, perimenopause, menopause, or prefer not to say) are two separate choices, each with its own consent, and you can switch either off at any time in Settings → Training Preferences.

Your cycle answers, the days you mark and your life stage are kept only on your phone, in the iPhone Keychain or the Android Keystore. They never reach our database and never reach analytics. Daily check-ins kept on your phone hold only your 1–5 answers.

Nothing about your cycle leaves your phone. The app works out the training adjustment itself, and your workout request carries only that adjustment — “lower energy today, trim the volume” — with no cause, no date and no phase.

If you turn on life stage, each workout request carries the training constraint your stage implies — for example “no exercises lying on your back” — to the AI providers in section 3. The stage itself never leaves your phone, and neither does any date. Be aware that a constraint like that can let a provider guess the stage behind it.

“Erase cycle data” in Settings deletes this data and both consent records, and takes the period answers out of the check-ins stored on your phone. Deleting your account does the same. Switching a consent off stops the app using it from your next workout on.

5. Outside the EU

Some of these providers are based outside the EU, mainly in the US. Transfers to them rely on the EU's standard contractual clauses or the EU-US Data Privacy Framework.

6. How long we keep it

As long as your account exists, except workout requests, which we keep for 12 months. Deleting your account in the app (Settings → Privacy & account) removes it and everything linked to it straight away, including analytics. A little anonymous usage data from before you signed up can't be linked to you and stays. Waitlist addresses are kept until you unsubscribe.

7. Your rights

You can ask to see, correct, delete or get a copy of your data, limit how we use it, and object to it. Email im@peakness.app. You can also complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens.

8. Children

PEAKNESS is not for anyone under 16, and we don't knowingly collect their data. If a child has given us data, contact us and we'll delete it.

9. Changes

We post changes here and update the date above.
