Privacy Policy

Strike20 app · Last updated: [date of publication]

1. Who is responsible

The controller responsible for your personal data is:
Luke Strike, [business name, if different]
[street address, postcode, town], Switzerland
Email: luke@strike20.ch

This policy explains how the Strike20 app ("the app", "we") handles your personal data under the Swiss Federal Act on Data Protection (FADP) and, where it applies, the EU General Data Protection Regulation (GDPR).

2. Data that stays on your phone

The following is stored only on your device and is not sent to us, unless described in sections 3–6:

• Your profile from onboarding: training goal, experience level, sex, age, height, current and goal weight, activity level, equipment, fasting window, diet and allergies.
• Your calorie, macro and protein targets, meal plans, favourite and hidden meals, and which meals you tick off.
• Your workout history, sets and reps, and notes.
• Your Neuro Score test results.
• Injured areas, injury notes and goals you enter in your training profile.

Deleting the app deletes this data. We can't recover it.

Apple Health (optional). If you connect Apple Health in Profile → Apple Health, the app saves your finished workouts (with an estimate of calories burned) to Apple Health, and reads your body weight, step count and resting heart rate. You choose exactly what to allow in Apple's permission screen and can change it any time in the Health app. Data read from Apple Health stays on your phone, unless you also turn on sharing it with your coach (section 5). We never use Apple Health data for advertising, never sell it, and never share it with anyone else.

3. Subscriptions

Subscriptions are sold and billed by Apple. We never receive your name, Apple ID or payment details. To confirm which plan you have, the app sends us Apple's signed record of your subscription, which contains a transaction ID, the product (plan) and its expiry date. We use it only to check your subscription and to apply daily limits. Apple's handling of your purchase is covered by Apple's privacy policy.

4. Building your workouts (paid plans)

When you ask for a new workout, the app sends a request to our server, which passes the details below to Anthropic, a service that writes the workout for us:

• The workout type (Push, Pull or Legs), your experience level, equipment and training goal.
• On Pro and Neuro Elite: a summary of your recent workouts of that type (dates, exercises, targets and reps achieved).
• On Neuro Elite: your injured areas, any injury notes and goals you've written, and your coach's instructions for you.

We do not send your name, email, weight, age or meal data for this. Injury information can be health data; we only send it so your workouts avoid exercises that could aggravate an injury, and only if you've entered it.

Anthropic acts as our service provider (processor) and processes these requests on our instructions. Under its commercial terms it does not use this data to train its models. It may keep requests for a limited period for security and abuse monitoring, as set out in Anthropic's privacy policy. Anthropic is based in the United States; see section 9.

To keep usage fair, our server counts how many workouts each subscription builds per day (transaction ID, date and count).

Exercise demo videos are downloaded from our server. Like any website, our hosting provider sees your device's IP address when you load them.

5. Sharing your progress with your coach (Neuro Elite, only with your consent)

Neuro Elite includes personal coaching. With your explicit consent, given on the "Share your progress" screen in the app, the app sends the following to our server so your coach can see it:

• The first name and email you enter, so your coach can contact you.
• Your training goal, level, equipment, injured areas, injury notes and goals.
• Age, sex, height, current and goal weight, activity level, fasting window, diet, allergies, brain goal, and your calorie, protein, carb, fat and fibre targets.
• Your workouts from the last 90 days (date, type, length, reps).
• Which planned meals you ticked off in the last 30 days, with calories and protein.
• Your Neuro Score results.
• Only if you separately turn on "Share with my coach" in Profile → Apple Health: your weigh-ins from the last 90 days, and your daily step count and resting heart rate from the last 30 days, read from Apple Health. Turning this off deletes it from our server at the next update.

Some of this is health data. We process it only on the basis of your explicit consent and only for your coaching. It is updated automatically while sharing is on. Only your coach can view it, through a password-protected dashboard.

Your coach can also save instructions for your workouts (a focus, intensity, exercises to include or avoid, and a message to you). These are stored with your account and used when your workouts are built.

You can withdraw consent at any time in the app under Profile → Your coach. Withdrawing deletes the shared data and your coach's instructions from our server straight away. Withdrawal does not affect the lawfulness of processing before it.

6. Neuro Elite places and waitlist

Because Neuro Elite includes the coach's time, places are limited. The app of each Neuro Elite member periodically confirms the membership to our server (transaction ID and expiry date) so we know how many places are taken. If Neuro Elite is full and you join the waitlist, we store the email address and the optional first name you enter, and use them only to tell you when a place opens.

7. Who processes your data

We don't sell or rent your data, and we don't share it with advertisers or data brokers. We may disclose data if required by law.

8. How long we keep data

• Coach sharing data and your coach's instructions: until you withdraw consent, or 30 days after your Neuro Elite membership ends, whichever is first.
• Daily workout counters: 90 days.
• Neuro Elite membership records: 30 days after the membership ends.
• Waitlist: until we've offered you a place or you ask us to remove you.
• Workout requests at Anthropic: as set out in Anthropic's policy (section 4).

9. International transfers

Our database is in Switzerland. Workout requests (section 4) are processed by Anthropic in the United States. Where data goes to a country without an adequate level of data protection, we rely on appropriate safeguards such as the Standard Contractual Clauses (as recognised by the Swiss Federal Data Protection and Information Commissioner) and, where applicable, the Swiss-US Data Privacy Framework. [Confirm the safeguard Anthropic's data processing terms provide.]

10. Legal bases (GDPR, where it applies)

• Providing the app, building workouts and checking subscriptions: performance of our contract with you (Art. 6(1)(b)).
• Injury information used to build workouts, and coach sharing: your explicit consent (Art. 6(1)(a) and 9(2)(a)).
• Daily limits and security: our legitimate interest in keeping the service fair and secure (Art. 6(1)(f)).
• Waitlist: your consent (Art. 6(1)(a)).

11. Your rights

You can ask us for access to the personal data we hold about you, and to correct, delete or restrict it, receive it in a portable format, or object to its processing. Where we rely on consent, you can withdraw it at any time. Email luke@strike20.ch; we'll reply within 30 days. You can also complain to the Swiss Federal Data Protection and Information Commissioner (edoeb.admin.ch) or, in the EU, your local data protection authority.

12. Security

Data is sent over encrypted connections. Our database can only be read by our server; client data is visible only to the coach after signing in. No system is perfectly secure, but we limit what we collect and how long we keep it.

13. Health information and age

Strike20 provides general fitness, nutrition and educational information. It is not medical advice, and the Neuro Score is a personal benchmark, not a medical test. The app is intended for adults aged 18 and over.

14. Changes

If we change this policy, we'll update the date above and, for significant changes, tell you in the app.
