Coach nutrition and training in one app

🔒 Privacy Policy

Who we are

Micro Macro Nutri Labs (Martin Fabian, see Impressum below) operates the CoachIn1 mobile application ("the App"). The App connects coaches with their clients. This policy explains what data we collect, who can see it, how we use it, and your rights.

Data we collect

• Account information – your email address, your name, and a password. Passwords are stored only in hashed form by our authentication provider and are never visible to us.
• Client details entered by coaches – when a coach adds a client, the coach provides the client's name and email address. This is used to send the client an invitation email and to link the client to that coach.
• Meal plans – meals and foods with amounts, calories, protein, carbohydrates and fat, created by coaches and assigned to clients.
• Training plans – training sessions, exercises, sets, rep ranges, cardio duration, intensity and notes, created by coaches and assigned to clients.
• Workout logs – workouts clients record, including date, exercises, sets, repetitions, weights, cardio activities, durations and notes.
• Coach notes – short notes a coach leaves for a client, and when the client marked them done.
• Weight unit – whether a client logs weights in kilograms or pounds.
• Authentication tokens – short-lived session tokens that keep you signed in. They are stored encrypted on your device.
• Technical logs – our hosting provider automatically records technical data such as IP addresses and request timestamps when the App talks to our servers, for security and troubleshooting.

Workout logs can reveal information about your health and fitness. We process this data only to provide the App's coaching features and only with your consent, which you give by entering it.

Data we do NOT collect

• We do not access your location, contacts, camera, photos or microphone.
• We do not use advertising or analytics SDKs, and we do not track your activity across other apps or websites.
• We do not collect payment card or banking information. Any payment arrangement between a coach and a client happens outside the App.
• We do not sell, rent, or share your personal data with third parties for marketing purposes.

Who can see your data

• If you are a client, every coach you are linked to can see your name, email address, the plans they assigned to you, your workout logs, and whether you marked their notes done.
• If you are a coach, your name and the plans you assign are visible to the clients you assign them to.
• No one else using the App can see your data. Access is enforced on the server for every request.

How we use your data

• To create and secure your account and keep you signed in.
• To send invitation, confirmation and password emails.
• To store, sync and display plans and logs between coaches and their clients.
• To keep the service secure and fix technical problems.

Legal bases (GDPR)

• Performance of a contract (Art. 6(1)(b) GDPR) – providing the App and your account.
• Consent (Art. 6(1)(a) and Art. 9(2)(a) GDPR) – workout logs that may contain health-related data. You can withdraw consent at any time by deleting the data or your account.
• Legitimate interests (Art. 6(1)(f) GDPR) – security and technical logs.
• Coaches who enter a client's name and email are responsible for having a lawful basis to do so, typically their existing coaching relationship with that client.

Third-party services

The App uses the following service providers, each governed by their own privacy policies:

• Supabase (Supabase, Inc.) – database hosting, user authentication, server functions and transactional emails (invitations, confirmations, password resets). All App data described above is stored with Supabase on servers in the EU (Ireland).
• Google Play (Google LLC) – distribution of the App on Android.
• Apple (Apple Inc.) – distribution of the App on iPhone.

Where a provider processes data outside the European Economic Area, the transfer is protected by the European Commission's Standard Contractual Clauses or an equivalent safeguard.

Data retention & deletion

• Your data is kept for as long as you have an account.
• When a coach removes a client, the plans that coach made for the client are deleted. If the client is not linked to any other coach, the client profile and all of the client's workout logs and notes are deleted as well.
• To delete your account and all associated data, use the account deletion page or contact us at the address below. Deletion is completed within 30 days.

Your rights

Under the GDPR you have the right to access, rectify, erase, restrict and port your data, to object to processing, and to withdraw consent at any time. To exercise these rights, contact us at the address below. You also have the right to lodge a complaint with a data protection supervisory authority.

Children's privacy

The App is not directed at children under 16. We do not knowingly collect personal information from children.

Changes to this policy

We may update this policy from time to time. The effective date below will be updated accordingly. Continued use of the App after changes constitutes acceptance.

Effective date: 6 October 2026

⚕️ Health & Fitness Disclaimer

CoachIn1 is a communication and planning tool between coaches and their clients. It is not a medical device, and no information in the App constitutes medical advice, diagnosis, or treatment.

Coaches are independent

Coaches using the App are independent of Micro Macro Nutri Labs. We do not employ, vet or verify the qualifications of coaches, and we are not responsible for the plans, advice or content they provide. Any coaching relationship, including fees, is solely between the coach and the client.

No liability for health outcomes

To the fullest extent permitted by applicable law, Micro Macro Nutri Labs and its developers shall not be liable for any direct, indirect, incidental, or consequential damages arising from:

• Any use or misuse of the App.

📋 Terms of Use

Coaches may register an account themselves. Client accounts are created by invitation from a coach. You are responsible for keeping your login credentials confidential and for all activity under your account.

Coach responsibilities

• Only invite people who have agreed to be coached by you and to have their data processed in the App.
• You are solely responsible for the plans and advice you provide and for complying with any professional rules that apply to you.
• Fees and contracts with your clients are outside the App and are your own responsibility.

Acceptable use

You may not use the App for anything unlawful, upload content that infringes the rights of others, attempt to access data of users you are not linked to, or interfere with the App's operation. You may not reverse-engineer, copy, or redistribute the App.

Your content

You keep ownership of the plans, logs and other content you enter. You grant us the right to store and display that content to the users you share it with, solely to operate the App.

Termination

You can stop using the App and delete your account at any time. We may suspend or terminate accounts that violate these terms.

Limitation of liability

The App is provided "as is" without warranties of any kind, express or implied. Micro Macro Nutri Labs is not liable for any loss of data, service interruptions, or other damages arising from use of the App, except where liability cannot be excluded by law (such as for intent or gross negligence).

Governing law

These terms are governed by the laws of the Federal Republic of Germany, without regard to conflict-of-law provisions. Mandatory consumer protection laws of your country of residence remain unaffected.
