Terms of Service

By accessing or using Fittssy™ (‘the App’), you agree to be bound by these Terms of Service and our Privacy Policy. If you do not agree to these terms, do not use the App.

You must be at least 16 years old to use Fittssy. By creating an account, you confirm that you meet this age requirement.

Fittssy™ is a fitness and wellness tracking application. You may use it to create workout templates, log exercise sessions, track cardio activities, log mindfulness and breathing sessions, record nutrition and macros, run interval timers, build multi-week training programs, generate AI-powered workout plans, connect wearable devices via Health Connect, and review your training history.

You agree to use the App only for its intended purpose. You must not: (a) attempt to gain unauthorized access to any part of the service, (b) use the App to distribute malicious software, (c) interfere with or disrupt the service, (d) scrape or extract data from the App for commercial use, or (e) impersonate another user or entity.

You may use Fittssy™ as a guest (Ghost Protocol) without creating an account. Guest data is stored locally on your device and is not backed up. If you log out, clear your browser data, or uninstall the app, all guest data will be permanently lost. To protect your data, create an account.

If you create an account, you are responsible for maintaining the security of your credentials. You must provide accurate information and keep it up to date. You are responsible for all activity that occurs under your account.

You retain ownership of all content you create in the App, including workout templates, session logs, custom exercises, nutrition entries, mindfulness records, and program templates.

By using the App, you grant us a limited, non-exclusive license to store and process your content solely for the purpose of providing the service to you. We do not use your content for any other purpose.

Social Content: If you enable a public profile, your display name and completed workout session summaries (exercise list, duration, volume) become visible to your followers. You remain in full control — disabling your public profile immediately removes your content from all feeds. You must not post misleading, abusive, or inappropriate content in any public-facing feature (display name, workout names). We reserve the right to disable public profiles that violate these terms.

Workout DNA (QR Sharing): When you generate a shareable QR code for a workout template, a public snapshot of that workout is created and accessible to anyone with the link. You are responsible for ensuring shared workout content is appropriate. Do not share proprietary or third-party workout programs without permission.

Challenges: When you create a challenge and invite participants, you are responsible for setting fair terms and a reasonable time period. Challenges are visible to all participants and their followers.

Fittssy offers optional AI-powered features that generate personalized workout programs and exercise protocols based on your preferences. These features use third-party AI services (Anthropic Claude) to process your inputs.

AI-generated workout plans are suggestions only and should not be treated as professional fitness advice. You are responsible for evaluating whether any AI-generated exercise program is appropriate for your fitness level and health condition. AI-generated content is labelled with an ‘AI’ badge in the app. AI features are experimental by nature — outputs are not guaranteed to be suitable, optimal, or free from errors. By using AI generation, you acknowledge that (a) outputs are produced probabilistically and may contain inaccuracies, (b) any reliance on an AI-generated plan is at your own risk, (c) Fittssy™ provides no warranty that a generated plan will achieve any specific outcome, and (d) the health disclaimer section below applies in full to all AI-generated content.

AI generation features require a NETRUNNER subscription (paid tier). Subscribers receive 20 protocol generations and 3 program generations per month, resetting at the start of each billing period. AI-generated content may be edited or deleted at any time, just like any other user-created content.

Fittssy™ offers a paid subscription tier (NETRUNNER) on the web and the Android app, billed monthly (£9.99) or annually (£99.99 — two months free compared to the monthly rate). New subscribers receive a 7-day free trial. Founding Operators (the first 2,000 qualifying users) receive a permanent 10% discount on all subscription payments. Full 30-day PR guarantee terms apply to NETRUNNER annual subscriptions only — see the pricing page for requirements. The iOS app is currently free with no NETRUNNER subscription tier available on iOS.

30-day PR guarantee (NETRUNNER Annual only): if you follow an AI-generated programme for 30 consecutive days, log 12 valid sessions (all prescribed sets logged on time and within ±10 minutes of the expected session duration), and fail to achieve a new personal record on any tracked exercise, you may request a refund of your first annual payment by emailing hello@fittssy.com within 7 days of day 30. The guarantee is limited to one claim per user, lifetime. Validity is determined by automated server-side checks at session completion. Missed or invalid sessions reset the valid-session count. One pause of up to 7 consecutive days is permitted per guarantee period.

All subscription payments are processed by Stripe. Fittssy™ never stores or has access to your card details. Subscriptions automatically renew at the end of each billing period unless cancelled. You may cancel at any time via the account page or the Stripe Customer Portal. Cancellation takes effect at the end of the current billing period — you retain access to paid features until then.

Outside of the 30-day PR guarantee above, all subscription sales are final. Refunds are not provided for partial billing periods, unused time, or change of mind. If you cancel mid-cycle, you will not receive a pro-rated refund for the remaining days. By subscribing, you acknowledge and accept this no-refund policy.

For subscriptions purchased through Google Play, refund requests are subject to Google’s own refund policies and must be directed to Google Play Support, not Fittssy.

LEGEND is a limited one-time purchase edition of Fittssy, capped at five hundred (500) publicly available units plus a small separate Founding Team cohort. Each LEGEND purchase is £499 (or the then-current publicly listed price), processed by Stripe, and grants: (a) lifetime access to NETRUNNER features at no further charge, (b) lifetime access to the ARCHITECT tier when it launches, (c) the complete DARKFIELD digital monograph library at the time of purchase, (d) a personalised Operator Journal and Operator Dossier delivered by email, (e) a permanent Operator number in the range 0001–0500, (f) the LEGEND Operator Frame and Sigil applied to your in-app profile (cosmetic), and (g) one permanent vote on future roadmap decisions. Item scope may be updated from time to time — changes will favour the buyer and will never remove an entitlement already granted.

Your LEGEND Operator number is allocated on a first-paid, first-numbered basis via an atomic database operation, is permanent, and cannot be transferred, swapped, or resold. The LEGEND edition itself is non-transferable — it is tied to the purchasing account. If you delete your account after a LEGEND purchase, the Operator number is retired and not re-issued.

Digital products: Fittssy also sells one-time digital products (DARKFIELD monographs, Operator Starter Kit where paid, and similar) at published prices. Each purchase grants a personal, non-exclusive, non-transferable, perpetual licence to download and use the delivered file(s) for your own training purposes. You may not redistribute, resell, publish, or create derivative works from any delivered file.

Delivery of digital products is via a time-limited signed URL sent to the purchase email, plus a permanent re-download link at /account/library (for registered users) or /lost-download (magic link for guest purchases). Because digital products are delivered immediately and in full, you expressly waive your UK consumer right to cancel under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 for any digital product that has been delivered. If a delivered product fails to match its published description, email hello@fittssy.com within 14 days and we will investigate on a case-by-case basis.

LEGEND edition is excluded from the 30-day PR guarantee and any other subscription-refund terms, because it is a one-time purchase, not a subscription.

Fittssy™ may optionally connect to Google Health Connect (Android only) to import health data from connected wearable devices. We request READ-ONLY access to 7 data types: exercise sessions, sleep sessions, daily steps, active calories, resting heart rate, heart rate samples, and distance. We never write data to Health Connect. This integration requires your explicit consent and can be revoked at any time via Android Settings → Health Connect → App permissions → Fittssy.

You may also manually import fitness data by uploading .fit or .gpx files. All health data is stored in your personal account and is accessible only to you.

You may delete all wearable data at any time via Profile → Wearables → Delete Wearable Data.

Fittssy™ is not a medical device, medical app, or fitness advisory service. The App, including any health data displayed from wearable devices and any AI-generated workout plans, is provided for informational and tracking purposes only. Nothing in the App constitutes medical advice, diagnosis, or treatment.

Always consult a qualified healthcare or fitness professional before starting any exercise or wellness program. You exercise and use the App at your own risk. Fittssy™ is not responsible for any injury, illness, or adverse health outcome arising from your use of the App or reliance on data displayed within it.

Fittssy™ is available as a web application, an Android app (Google Play), and an iOS app (Apple App Store). The App requires an internet connection for account features, though limited offline functionality is available via cached data.

We aim to keep the service available, but do not guarantee uninterrupted access. We may perform maintenance, updates, or changes that temporarily affect availability. We will make reasonable efforts to provide notice of planned downtime.

Fittssy operates an invite and affiliate system. When you share an invite link (SOC4 — Share Operator Clearance) containing your Operator code, new users who sign up through that link are attributed to you for analytics and, where a commission programme is active, for affiliate payouts. Attribution is stored as an `attribution_source_operator_id` on the invited user’s account; it is set once at registration and never changed afterwards. The referrer is not granted access to any of the referred user’s personal or workout data — only anonymised milestone counts (e.g. ‘you have brought in 10 Operators’).

Affiliate payouts, where offered, are paid via Stripe Connect. To receive payouts you must complete Stripe’s standard KYC onboarding; Stripe’s Connected Account Agreement governs the payout relationship. Commission terms, eligible products, and payout schedule are published on the relevant creator page and may be updated from time to time. We reserve the right to reverse a commission if the underlying subscription or purchase is refunded, charged back, or determined to be fraudulent.

You must not use misleading, spammy, or deceptive channels to drive referrals. This includes, without limitation: paid ad campaigns making claims we have not authorised, incentive schemes that violate a platform’s rules, and any form of automated or bot-driven sign-up. Breach of this rule may result in suspension of your affiliate account and forfeiture of pending commissions.

The Fittssy™ name, logo, interface design, cyberpunk theme, and all original content are the property of the App’s creators. Fittssy™ is a trademark. You may not copy, modify, distribute, or create derivative works from any part of the App without prior written permission.

The exercise library (1,020 system exercises) is provided for your personal use within the App and may not be extracted or republished.

Fittssy™ is provided ‘as is’ and ‘as available’ without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

Health and fitness data synced from third-party sources (wearables, Health Connect) is provided for convenience and may not be accurate. Do not rely on this data for medical decisions.

AI-generated content is provided as a convenience and may not be suitable for all users. Always use your own judgement when following any workout plan.

To the maximum extent permitted by applicable law, Fittssy™ and its creators shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the App.

This includes, but is not limited to: loss of data, physical injury from exercise, health decisions made based on App data or AI-generated content, any interruption of service, or unauthorized access to your account.

Our total liability to you for any claims arising from or related to the App shall not exceed the amount you have paid to us in the 12 months preceding the claim, or £10 (ten pounds sterling), whichever is greater.

We reserve the right to suspend or terminate your access to the App if you violate these Terms, engage in abusive behaviour, or for any reason at our discretion, with or without notice.

You may stop using the App at any time. Guest data can be deleted by exiting Ghost Protocol. For full account deletion, go to Profile → Delete Account. Your data will be permanently deleted within 30 days of your request, except purchase transaction records which we are legally required to retain for seven years under UK tax law — see our Privacy Policy (Data Retention section) for the precise scope.

These Terms are governed by and construed in accordance with the laws of England and Wales, without regard to conflict of law principles. Any disputes arising from these Terms or your use of the App shall be subject to the exclusive jurisdiction of the courts of England and Wales.

If you are a consumer in the European Union, you retain any mandatory consumer protection rights under the laws of your country of residence.

Fittssy™ is available in 10 languages: English, Hungarian, German, Spanish, French, Portuguese, Russian, Chinese Simplified, Japanese, and Korean. You may change the app language at any time via Profile → Language.

These Terms of Service and the Privacy Policy are provided in English only and are the legally binding version. Translations of in-app content are provided for convenience and do not constitute legal representations.

In the event of any inconsistency between the English and a translated version of in-app content, the English version shall prevail.

We may update these Terms of Service from time to time to reflect changes in our practices, features, or legal requirements. We will update the ‘Last updated’ date at the top of this page when changes are made.

Continued use of the App after changes are posted constitutes your acceptance of the updated terms. If material changes are made, we will make reasonable efforts to notify you (e.g., via in-app notification or email).

For questions about these terms: email legal@fittssy.com.

You may also use the in-app feedback tool (tap the floating button on any page, select ‘Feedback’).

Fittssy™ is operated by an independent developer based in the United Kingdom.
