Privacy Policy

Strength Academy SARL ("Strength Academy", "we", "us", or "our") is a company incorporated in Switzerland that provides a digital platform dedicated to sports training programming, performance tracking, nutrition management, mobility assessment, and online coaching through its website and web application available at https://strengthacademy.app (the "Platform").

We place great importance on the protection of your personal data and are committed to processing it in accordance with the Swiss Federal Act on Data Protection (FADP) and, where applicable, the General Data Protection Regulation (GDPR). This Privacy Policy describes how we collect, use, store, and share your personal information when you access or use the Platform as an athlete ("Client") or as a professional coach ("Coach").

By creating an account or using the Platform, you acknowledge that you have read and understood this Privacy Policy.

This Privacy Policy should be read together with our Terms of Service.

1. Information We Collect

We collect personal data in order to operate, improve, and personalize the services offered on the Platform. The nature of the data collected depends on your role and how you interact with the Platform.

When you create an account as an athlete, we collect identification and account information such as your name, email address, password (stored in encrypted form), profile picture, and date of birth. To enable training, mobility, performance tracking, and nutrition-related features, you may also voluntarily provide health and physical data, including body weight, height, body composition indicators, mobility test results, pain or discomfort areas, injury-related information, activity levels, and training performance metrics. These data are considered sensitive personal data under applicable data protection laws and are processed only on the basis of your explicit consent, which you may withdraw at any time.

The Platform also allows athletes to enter nutrition-related information, including dietary objectives, caloric targets, macronutrient goals, food logs, and descriptions of meals. You may also upload photographs of meals for nutritional analysis. In addition, athletes may upload user-generated content such as training videos, progress photos, written comments, and messages in private or group community chats.

When you make a purchase on the Platform, we collect transaction-related information such as the products purchased, subscription details, and payment status. Strength Academy does not store full credit card numbers. All payment transactions are processed securely by our third-party payment service provider Stripe.

When you create an account as a coach, we collect professional and business-related information, including your name, email address, profile photo, professional biography, certifications, and contact details. We also process the content you create on the Platform, such as training programs, exercise libraries, feedback provided to athletes, and communications with clients. For payout purposes, we collect financial information such as bank account identifiers (IBAN/SWIFT), which are processed through Stripe Connect.

Connected social media accounts (Instagram). Coaches may optionally connect their own Instagram professional account through Instagram Login in order to publish content they create on the Platform. When you connect an account, we receive and store your Instagram account ID, username, and an access token (stored in encrypted form). This data is used solely to display which account is connected and to publish content to that account on your explicit instruction; we never access your Instagram password and never post without your action. You can disconnect the account at any time within the Platform, or request deletion of this data by emailing info@strengthacademy.app. Upon disconnection or request, the access token and associated account data are deleted from our systems.

In addition to information you provide directly, we automatically collect certain technical and usage data when you access the Platform. This may include your IP address, device type, operating system, browser type, access dates and times, log files, and information about how you interact with the Platform. We also use cookies and similar technologies to ensure the proper functioning of the Platform, maintain user sessions, remember preferences, and analyze usage patterns. You may manage cookie preferences through your browser settings, although disabling cookies may affect certain features.

On our public website we additionally use advertising and analytics cookies from Google (Google Ads, Google Analytics) and Meta only after you accept them in the cookie banner. They let us measure which campaigns and pages bring coaches and athletes to the Platform. These advertising and analytics scripts load only after acceptance. With consent, we also keep first- and last-visit campaign information and a short page history for up to 30 days to connect website visits with a signup or booking. The cookie choice is shared across our website and app subdomains for 180 days. Use Cookie settings on the website to change your choice or withdraw consent. Withdrawal clears optional website attribution and advertising cookies; it does not erase records already saved. Contact us to request deletion of those records.

Website analytics and visit recordings. On every visit to our public website we measure page views, clicks and scrolling with PostHog, hosted in the EU, without cookies and without storing anything on your device. If you sign up or book from that visit, we link the visit to your account so we can see which pages led there. If you accept cookies, PostHog also records the visit (what you click, scroll and see on our pages) so we can find what is confusing; what you type into forms stays hidden. Withdrawing consent in Cookie settings stops the recording. Recordings are deleted after 90 days at the latest. If you accept cookies, these measurements also carry the random visitor ID we keep for attribution, so we can see which of your earlier visits led to a signup.

Measuring our ads. When you create a coach account or pay for a subscription, we send Meta and Google a hashed (SHA-256) copy of your email address, the ad click identifier from the link you arrived on (if any), the browser type and the time of the signup or payment. They use it only to tell us which of our ads bring customers and to improve how our ads are delivered; a hash cannot be turned back into your email address. If you only leave your email in a form or book a call, we send this only if you accepted cookies. Meta Platforms Ireland and Google Ireland receive this data as independent controllers under their own privacy policies.

Ads for coaches who tried the app. When you create a coach account, we upload a hashed (SHA-256) copy of your email address, phone number and country to Meta once a day, so that we can show our ads on Facebook and Instagram to coaches who started a trial and leave out coaches who already pay. Meta uses the hashes only to find matching accounts and deletes them after matching, under its Custom Audience terms; it never receives your training data, clients or messages. We do this on the basis of our legitimate interest in reaching people who already tried the Platform. You can object at any time with the "Don't personalise my emails" link at the bottom of any of our emails, or by replying to one of them, and we take you off the list at the next daily refresh. You can also hide our ads in your Meta ad settings.

Brand quiz and coach page from Instagram. If you ask us in an Instagram message for our brand quiz or a coach page, we keep your Instagram username, the email address you send us and, for the quiz, your answers. We use them, with your public Instagram profile and posts, to show you your brand inside Strength Academy (a brand book, a coaching app and a coach page in the brand you picked), and to send you the link by Instagram message and by email. Nothing of it is public unless you claim it. Ask us at info@strengthacademy.app to delete the page and this data at any time.

Tailored emails. We tailor our onboarding and nurture emails to each coach's setup: the ad you came from, how you use the app and which links you click in our emails. We do this on the basis of our legitimate interest in sending you emails that fit where you are. You can object at any time with the "Don't personalise my emails" link at the bottom of any of our emails, or by replying to one of them. We only measure whether you open our emails or click their links if you accepted cookies on our website, and we stop when you object.

Phone calls about your account. When you create a coach account you can give us your phone number. A member of our team may use it to call you, usually once soon after you sign up, to help you set up your account and answer your questions. If we miss you, we may leave one short voicemail and try once more. These calls are made by a person; they are not automated and not recorded. While you are using the app, that person may instead call you inside it: you see who is calling, choose whether to answer, and can turn these calls off from the call itself. In-app calls are voice only and not recorded. The sound goes directly between your device and ours; to connect it, the two devices exchange network addresses through our servers (deleted when the call ends) and use Google's public STUN service to find them. If you are in Germany or Austria, we only call you in the app after you have agreed to a call. To make the call useful, we may first look at public information about your coaching business, such as your website and public social media profiles, and use an AI tool to search for and summarise it. We keep short notes of the call with your account and delete them with it. We do this on the basis of our legitimate interest in helping new coaches get started. If your number is in Germany or Austria, we only call after you have agreed to a call. You can tell us at any time, on the call, by replying to any of our emails or by writing to info@strengthacademy.app, that you do not want to be called, and we will not call you again. Calls with our AI assistant, and the recording of any call, only happen if you separately opt in, and we explain them at that point.

Product analytics and setup recordings in the app. Product analytics in the app stay off until you allow them, and you can turn them off at any time in Profile settings. If you allow them as an athlete, we send signup steps, screen visits and workout saves to PostHog, without names, contact details, workout contents, health data or messages. If you allow them as a coach, we count which coach screens you visit, and during setup, only until your first athlete joins, PostHog records your screen so we can see where setup gets stuck. In the web app in your browser, a choice you made by accepting all cookies on our website (after 5 November 2026) counts as allowing this, unless you have answered in the app; the iPhone and Android apps always ask you in the app. A label shows while this recording runs. Recordings are linked to your account ID and show what you tap and type, except passwords, email addresses and phone numbers. Card details are entered on Stripe and are never recorded. PostHog stores this data in the EU, and recordings are deleted after 90 days at the latest.

2. How We Use Your Information

We process your personal data to provide and operate the Platform and its various functionalities. This includes creating and managing user accounts, generating training calendars, tracking athletic performance, visualizing progress through charts and statistics, calculating mobility scores, and delivering personalized nutrition targets.

Your data is also used to enable coaching features, including allowing designated coaches to access relevant athlete information such as training logs, uploaded videos, nutrition data, mobility results, and declared pain areas, in order to provide feedback and guidance. Communication features, such as private messaging and group discussions within the community space, also rely on the processing of personal data.

Certain features of the Platform rely on artificial intelligence technologies, particularly for nutrition tracking. When you upload a meal photo, the image is analyzed to identify food items and estimate caloric and macronutrient values. These features are provided for informational and tracking purposes only and do not constitute medical or dietary advice.

We also process personal data for payment and financial management purposes, including processing purchases, managing subscriptions, distributing revenues to coaches, issuing invoices, and handling refunds where applicable.

We use the contact details you give us, including your phone number if you provide one, to contact you about your account: to help you set it up, to answer your questions and to follow up on your trial, as described in section 1.

Additionally, we use data to ensure the security and integrity of the Platform, to detect and prevent fraud or misuse, to provide customer support, to troubleshoot technical issues, and to comply with applicable legal and regulatory obligations.

3. Sharing of Personal Data

Strength Academy does not sell your personal data.

When you enroll in a training program, connect with a coach, or participate in coaching services, you explicitly consent to the sharing of relevant personal data with that specific coach. This may include your profile information, training history, performance metrics, nutrition logs, mobility data, uploaded videos, and communications. Coaches operate as independent users of the Platform and may be subject to their own legal obligations regarding personal data processing. Strength Academy is not responsible for how coaches process personal data outside of the Platform.

We may share personal data with trusted third-party service providers who act as data processors on our behalf and only for the purposes necessary to deliver the services. These providers may include cloud hosting and infrastructure providers, video storage services, artificial intelligence service providers such as Anthropic (Claude) and OpenAI, payment processors such as Stripe, product analytics providers such as PostHog, providers that collect public web and social media pages for us (used only to prepare a call with a coach, as described in section 1), and email or notification service providers. All such providers are contractually bound to process data in accordance with our instructions and to implement appropriate security measures.

We may also disclose personal data where required to do so by law, regulation, court order, or other valid legal process, or where necessary to protect our rights, users, or the security of the Platform.

4. Artificial Intelligence and Automated Processing

The Platform uses artificial intelligence services provided by third parties, Anthropic (the Claude API) and OpenAI, to power its AI features. AI features are off by default and only activate after you give explicit consent in the app (the first time you open an AI feature, or in Profile → Settings → AI features). You can withdraw this consent at any time in the same settings, after which AI processing for your account stops, including automatically generated content.

Depending on the feature you use, the following data is transmitted securely to the AI provider for processing: for meal photo analysis (OpenAI), the food image you upload; for athlete intelligence, snapshots and stories (OpenAI), your training history (exercises, sets, reps, weights, rep maxes), recovery and readiness metrics including data synced from Apple Health, and your chat messages; for technique video analysis (Anthropic Claude), still frames extracted from the technique videos you choose to analyze; for coach assistant ("Jarvis") and programming analysis (Anthropic Claude), a coach-only feature, summaries of their athletes' training state, schedules, and business data, together with the coach's requests. The providers process this data only to return the requested analysis; we do not permit them to use it to train their models under our agreements with them.

You are responsible for ensuring that uploaded images and videos do not contain faces of third parties, identifiable individuals who have not consented, or sensitive personal information unrelated to the analysis. AI-generated outputs are estimates and informational only. They are not medical, therapeutic, or dietary advice and may not be fully accurate.

Google user data and Limited Use. Coaches may optionally connect their Google account so the Platform can read their calendar availability and create Google Meet events for bookings (Google Calendar API, calendar.events scope) and identify the connected account (userinfo.email). Strength Academy's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Google user data is used solely to provide these user-facing calendar and booking features. We do not transfer or sell Google user data, and no raw or derived Google user data is used to create, train, or improve any machine learning or artificial intelligence models. Google user data is never sent to the AI providers described above.

5. Data Storage and International Transfers

Personal data is primarily stored on servers located in Paris and/or within the European Economic Area. Some of our service providers may process data in other countries, including the United States. Where personal data is transferred outside Switzerland or the EEA, we ensure that appropriate safeguards are in place, such as Standard Contractual Clauses or other legally recognized transfer mechanisms, in compliance with applicable data protection laws.

6. Data Retention

We retain personal data only for as long as necessary to fulfill the purposes described in this Privacy Policy. Personal data is generally retained for the duration of your account. If you choose to delete your account, your personal data will be deleted or anonymized from our active systems within approximately 30 days, unless retention is required to comply with legal obligations. Financial and accounting records may be retained for up to 10 years in accordance with Swiss legal requirements.

7. Data Security

We implement appropriate technical and organizational measures to protect personal data against unauthorized access, alteration, disclosure, or destruction. These measures include encrypted communications, access controls, and secure storage practices. However, no system can guarantee absolute security, and you acknowledge that you use the Platform at your own risk.

8. Children's Privacy

The Platform is intended primarily for individuals aged 18 and over. Users between the ages of 13 and 17 may use the Platform only with the consent and involvement of a parent or legal guardian. We do not knowingly collect personal data from children under the age of 13. If we become aware that such data has been collected, we will take steps to delete it promptly.

9. Your Rights

Depending on your place of residence and applicable law, you may have the right to access your personal data, request correction of inaccurate or incomplete data, request deletion of your data, object to or restrict certain processing activities, request data portability, and withdraw your consent at any time. Requests to exercise these rights may be submitted by contacting us at info@strengthacademy.app. You also have the right to lodge a complaint with a competent data protection authority.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, or legal requirements. Any material changes will be communicated through the Platform or by email. Continued use of the Platform after the effective date of an updated policy constitutes acceptance of the revised Privacy Policy.
