🔒 Privacy Policy
Who we are
Micro Macro Nutri Labs (Martin Fabian, see Impressum below) operates CoachIn1 ("the App"), a marketplace on which independent coaches sell training plans, nutrition plans and monthly coaching, available as a web app (app.coachin1.com) and as iPhone and Android apps. 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, or the account details Google or Apple share when you sign in with them. Passwords are stored only in hashed form by our authentication provider and are never visible to us. When you sign up we ask you to confirm that you are 18 or older.
- Coach profiles and listings – if you sell: your public name, profile and physique photos, the languages you coach in, whether you sell as a business or privately, and your listings (titles, descriptions, covers, prices, files you attach and the plans themselves).
- Plans – training plans (sessions, exercises, sets, reps, cardio, notes) and nutrition plans (meals, foods, amounts, calories and macros) that coaches build or import.
- Purchases – what you bought, when, at what price, through which store, the store's transaction reference, and your consent to the buyer terms (including, where it applies, that you asked for access right away).
- Payout and tax details of coaches – account holder, IBAN, BIC, address, country, whether you sell as a business, tax number and whether the small business scheme applies; your sales, monthly statements and payouts. We are required to report sellers' details and sales to tax authorities (EU DAC7).
- Reviews – your star rating, your text, the optional before and after photos you add, and the coach's reply.
- Messages – the chat messages between buyers and coaches, blocks, and messages or reviews you report to us.
- Training data – workouts you log (date, exercises, sets, reps, weights, cardio, notes), your body weight and the progress photos you add, and your weight unit.
- Push notification tokens – if you allow notifications, a token for your device so we can tell you about new messages.
- Authentication tokens – short-lived session tokens that keep you signed in, stored on your device.
- Technical logs – our hosting providers automatically record technical data such as IP addresses and request timestamps, for security and troubleshooting.
- Ad source – if you open the web app through the link of one of our ads or posts, its campaign tags (utm parameters) are saved with your account when you sign up, so we know which ads bring users. No cookie is used for this.
Workout logs, body weight and progress photos can reveal information about your health. We process them only to provide the App's features and only with your consent, which you give by entering them.
Data we do NOT collect
- We do not access your location, contacts or microphone. The camera and photo library are used only when you choose to add a photo.
- The mobile apps contain no advertising or analytics SDKs, and we do not track your activity across other apps or websites. The web app only uses Google Ads measurement as described below, and sets its cookie only with your consent.
- We never see your payment card details. Purchases are paid through Apple, Google or Paddle, which handle payment details themselves.
- We do not sell, rent, or share your personal data with third parties for marketing purposes.
Who can see your data
- Everyone, also without an account: listings that are on sale, with the coach's public name, profile and physique photos, languages and seller status; and reviews of those listings with the reviewer's name, rating, text, before and after photos and the coach's reply.
- The coach you bought from: your name, what you bought from them, your messages with them, your review, and the training data or progress photos you choose to share with them.
- The people you chat with: your name and the messages in that conversation.
- Buyers of a plan: the plan they bought, also if the coach later changes or stops selling it.
- Us: we look at content that is reported to us (reviews, photos, messages) to decide whether to remove it, and use payout details only to pay coaches and meet tax duties.
- No one else 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 show listings, sell plans, deliver what you bought and keep it available to you.
- To pay coaches their share, issue statements and meet our tax and accounting duties.
- To deliver messages and notify you about them.
- To deal with reports and keep the marketplace safe.
- To send confirmation and password emails, and to fix technical problems.
Legal bases (GDPR)
- Performance of a contract (Art. 6(1)(b) GDPR) – providing the App, your account, purchases, sales, payouts and messages.
- Legal obligation (Art. 6(1)(c) GDPR) – keeping sales and payout records and reporting sellers to tax authorities (DAC7, German tax and commercial law).
- Consent (Art. 6(1)(a) and Art. 9(2)(a) GDPR) – workout logs, body weight and progress photos, and sharing them with a coach. You can withdraw consent at any time by deleting the data, stopping to share it, or deleting your account.
- Consent (Art. 6(1)(a) GDPR, § 25(1) TDDDG) – push notifications, and the Google Ads cookie in the web app.
- Legitimate interests (Art. 6(1)(f) GDPR) – security, technical logs, handling reports, and measuring which ads bring users (ad source, Google Ads notices without cookies).
Third-party services
The App uses the following service providers, each governed by their own privacy policies:
- Supabase (Supabase, Inc.) – database, file storage, user authentication, server functions and emails. All App data described above is stored with Supabase on servers in the EU (Ireland).
- Cloudflare (Cloudflare, Inc.) – hosts this website and the web app and delivers them to your browser.
- Apple and Google – distribute the App, offer sign-in with Apple or Google, and sell plans and coaching bought in the iPhone or Android app as resellers, under their own terms and privacy policies.
- Paddle (Paddle.com Market Ltd) – our reseller and Merchant of Record for purchases on the web. Paddle collects your name, email address, billing address and payment details to process the payment, invoice it and handle taxes, under its own privacy policy.
- RevenueCat (RevenueCat, Inc.) – manages purchases and subscriptions across the App Store, Google Play and Paddle. It receives your account ID and the details of your purchases (product, dates, price, store, taxes and fees), not your payment details.
- Expo (650 Industries, Inc.) – delivers push notifications to your phone. It receives your device's push token and the text of the notification.
- Anthropic (Anthropic PBC) and, as a fallback, Google Gemini (Google LLC) – read training and nutrition plans out of spreadsheets that coaches import. Only the contents of the imported file are sent; the providers do not use it to train their models.
- Google Ads (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland) – measures whether our ads lead to sign-ups and purchases in the web app. Only if you accept the banner in the web app does Google set a cookie (_gcl_aw) that links your sign-up or purchase to the ad you clicked, kept for up to 90 days. If you decline, no cookie is set; the web app then only sends Google notices without cookies or identifiers, from which Google makes aggregated estimates. Google may process this data in the USA; Google LLC is certified under the EU-US Data Privacy Framework. You can withdraw your consent at any time by deleting the site data of app.coachin1.com in your browser. The mobile apps send nothing to Google Ads. More: Google's privacy policy.
Where a provider processes data outside the European Economic Area, the transfer is protected by the European Commission's Standard Contractual Clauses, the EU-US Data Privacy Framework or an equivalent safeguard.
Data retention & deletion
- Your data is kept for as long as you have an account. You can delete photos, reviews, logs and messages you wrote at any time.
- Records of purchases, sales, statements and payouts are kept for as long as tax and commercial law require (in Germany up to 10 years), also after an account is deleted.
- To delete your account and all other associated data, use the account deletion page, delete it in the App (Profile), 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.
Age
The App is for people aged 18 and over. We do not knowingly collect personal information from minors.
Changes to this policy
We may update this policy from time to time. The effective date below will be updated accordingly, and we will tell you in the App about significant changes.
Effective date: 6 November 2026
⚕️ Health & Fitness Disclaimer
Plans on CoachIn1 are general fitness and nutrition guidance from independent coaches. CoachIn1 is not a medical device, and no information in the App constitutes medical advice, diagnosis, or treatment.
⚠️ Consult a qualified healthcare professional before starting a new diet or training programme — especially if you have or suspect a medical condition, have an injury, are pregnant, or are taking medication.
Coaches are independent
Coaches selling on CoachIn1 are independent of Micro Macro Nutri Labs. We do not employ them or verify their qualifications, and the content of their plans and advice is their responsibility. Reviews and before and after photos show individual experiences; results differ from person to person.
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 damages arising from following plans bought or created in the App, inaccuracies in nutritional values or other data, or injuries or adverse health effects resulting from exercise or dietary changes. This does not limit liability for intent, gross negligence, or injury to life, body or health caused by our own fault.
📋 Terms of Use
These terms apply to everyone using CoachIn1. Buying and selling plans are also covered by the terms for buyers and the terms for coaches, which you accept in the App before your first purchase or listing.
The platform
CoachIn1 is a marketplace. Plans and coaching are offered by independent coaches in their own name. When you buy a plan, your contract for the plan is with the coach named on the plan page; CoachIn1 provides the platform and is not a party to that contract.
Accounts
You must be 18 or older to use CoachIn1. Keep your login details confidential; you are responsible for activity under your account.
Buying
- Prices are set by the coach and include VAT.
- In the iPhone and Android apps, purchases are made and billed through Apple's App Store or Google Play under their terms. Monthly coaching is managed and cancelled in your App Store or Google Play account.
- On our website (app.coachin1.com), our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. Monthly coaching bought on the web can be cancelled through the link in your Paddle receipt.
- A one-off plan stays available in your account. Monthly coaching renews each month until you cancel it, and ends at the end of the month you paid for.
Selling
Coaches sell under the terms for coaches, which cover fees, payouts, statements, taxes and their responsibilities toward buyers. Selling is free; CoachIn1 takes a fee per sale as described under Fees.
Content and conduct
You keep ownership of what you add (plans, photos, reviews, messages) and allow us to store it and show it to the people it is meant for, and listings and reviews to everyone, to run and promote the marketplace. Don't post anything unlawful, misleading, hateful or sexual, or content you don't have the rights to, and don't harass other users. Reviews must reflect your own experience with the plan. You can report reviews, photos and messages in the App; we may remove content and suspend accounts that break these terms.
Termination
You can stop using the App and delete your account at any time. Plans you bought stay available while you have your account.
Limitation of liability
The App is provided as is. Micro Macro Nutri Labs is liable without limitation for intent, gross negligence and injury to life, body or health; otherwise only for breaching essential contractual obligations, limited to the damage that is typical and foreseeable. We are not responsible for the content of coaches' plans.
Governing law
These terms are governed by the laws of the Federal Republic of Germany. Mandatory consumer protection laws of your country of residence remain unaffected.
Effective date: 6 November 2026
💶 Refund Policy
Plans and coaching bought on our website
Payments on our website are processed by our reseller Paddle.com. If something is wrong with a purchase, for example the plan isn't what its page described or you were charged twice, write to info@coachin1.com with the email address of your account, or request a refund through the link in your Paddle receipt (or at paddle.net). Paddle issues refunds to the original payment method, usually within 5–10 business days. When a purchase is refunded, access to the plan ends.
Right of withdrawal
Plans are digital content that you get right after paying. When you buy from a coach who sells as a business, you ask for access right away and confirm that you then lose the 14-day right of withdrawal for that plan. You can still cancel monthly coaching at any time with effect from the next month.
Purchases in the iPhone or Android app
These are billed by Apple or Google, and refunds are handled by them under their policies. Request one at reportaproblem.apple.com for the App Store, or in your Google Play account (Payments & subscriptions → Budget & history) for Google Play. If you need help, contact us at info@coachin1.com.
