FitnX Terms of Service

These Terms govern the FitnX mobile, Apple Watch and Wear OS applications, website, support functions and related services (the Service), provided by Gellért Dániel individual entrepreneur (Gellért Dániel e.v.), registered at 2336 Dunavarsány, Erkel Ferenc utca 24., Hungary, registration number 59642088, tax number 90449813-1-33 (FitnX, we, us). Contact: support@fitnx.app.

1. Acceptance and eligibility

By creating an account or using FitnX, you agree to these Terms and acknowledge the Privacy Policy. If you do not agree, do not use the Service.

You must be at least 16 years old and have legal capacity to enter these Terms. If your local law requires additional capacity or guardian involvement, you may use FitnX only when those requirements are satisfied. You may not use the Service where prohibited by law.

2. What FitnX provides

FitnX is a fitness diary and activity-tracking service. It can record workouts and optional routes, use compatible phone/watch sensors, synchronize history, display statistics, manage exercises and measurements and connect supported health platforms.

Features vary by platform, device, permissions, region, app version and Free or Pro access. Internet is required for authentication, cloud synchronization, purchases, maps, support submission and some functions; many recording and history functions are designed for offline use.

3. Not medical advice; exercise risks

FitnX is not a medical device and does not provide medical advice, diagnosis, treatment, emergency monitoring, professional coaching or guaranteed results. Measurements, calories, sensor readings, routes, scores and statistics may be incomplete or inaccurate and must not be used for medical or safety-critical decisions.

Exercise can involve serious injury or death. Use suitable judgment, equipment and supervision; observe traffic, terrain, weather and local rules; and stop if you experience pain, faintness or unusual symptoms. Seek qualified advice before beginning or changing an exercise program where appropriate. In an emergency, contact local emergency services, not FitnX.

The Medical and Fitness Disclaimer forms part of these Terms.

4. Accounts and security

Provide accurate information and keep your sign-in method secure. You are responsible for account activity except to the extent caused by our breach. Notify support@fitnx.app promptly about suspected unauthorized access. Google and Apple sign-in are also subject to provider terms; loss of that external account may affect FitnX access.

5. Your content and licence

You retain rights in workout definitions, notes, support content and other material you submit (User Content). You grant us a worldwide, non-exclusive, royalty-free licence to host, reproduce, format, transmit, back up and otherwise process User Content only as reasonably needed to operate, secure and support the Service, follow your settings and meet legal obligations.

You confirm you have the necessary rights and that your content violates no law or third-party rights. Do not add unnecessary sensitive information to notes, tickets or screenshots.

6. Acceptable use

You must not:

• bypass security or access another user’s data;
• upload malware or unlawful, abusive, infringing or deceptive content;
• interfere with the Service, automate abusive requests, scrape protected data or evade limits;
• use health/fitness data for unlawful surveillance, discrimination, advertising profiling, insurance, credit or employment decisions; or
• resell or commercially exploit the Service without written permission.

7. Free and Pro

Free provides access to the current calendar month plus the preceding five calendar months of history. Free history is stored for a rolling 365 days, so older retained data may be locked. Active Pro provides unlimited history access/retention while active.

When Pro expires, Free access resumes immediately. Older history is protected for 365 days after expiry; after that, history outside the rolling Free retention window may be deleted. Resubscribing before cleanup restores access and cancels the scheduled cleanup. The Privacy Policy contains the authoritative retention details.

We may change features prospectively, without removing mandatory consumer rights. Material paid-service changes will be handled as applicable law and store rules require.

8. Purchases, renewal, cancellation and refunds

Pro subscriptions are purchased through Apple App Store or Google Play. The store shows price, currency, billing period, trial, taxes and renewal terms before purchase. The store processes payment and its terms also apply.

Unless cancelled, subscriptions may renew automatically as disclosed by the store. Manage or cancel in the store account used to purchase. Deleting FitnX or your account does not cancel a subscription. Cancellation normally stops future renewal while Pro continues through the paid period, subject to store rules. Refunds and withdrawal requests are handled under applicable law and the relevant store policy.

EEA consumers retain mandatory withdrawal and digital-service conformity rights. Immediate supply, store intermediation and consent given in the purchase flow may affect how withdrawal works. Australian, UK and other consumers retain all non-excludable guarantees and remedies.

RevenueCat validates entitlement status but does not process your card. Deleting its customer record does not cancel a store subscription.

Pro features and subscription-price protection

FitnX Pro provides the premium features presented on the purchase screen at the time of subscription. These may include increased workout and custom-exercise limits, extended history and statistics, custom date ranges, watch features, detailed activity and muscle insights, workout autofill, and personalization options. Availability may vary by platform, device, permissions, region, and app version.

If your purchase screen expressly states that your subscription price is protected, FitnX will not voluntarily increase the base price of that same subscription while it remains continuously active on the same plan, billing period, app-store account, and storefront.

Price protection does not apply after cancellation, expiration, failed renewal, resubscription, or a voluntary change of plan, billing period, app-store account, or storefront. It also does not prevent changes to taxes or changes required by applicable law or imposed through circumstances affecting the customer-facing price that FitnX cannot reasonably control.

Any permitted price change will apply only to a future renewal and will be communicated and processed through the Apple App Store or Google Play in accordance with applicable law and store rules. Where consent is required, the higher price will not apply unless the subscriber provides that consent.

9. Third-party services and devices

FitnX can interact with Firebase, Google Sign-In, Sign in with Apple, Apple Health/HealthKit, Android Health Connect, Apple Watch, Wear OS, RevenueCat, MapTiler, App Store and Google Play. Their terms and permissions also apply. We are not responsible for third-party services beyond duties law does not allow us to exclude.

You control optional location and health permissions and are responsible for compatible, safely maintained devices and connectivity.

10. Intellectual property

FitnX software, design, branding, catalogue content and documentation are owned by us or licensors and protected by law. We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the app for its intended non-commercial purpose on devices you control, subject to store usage rules. Open-source components remain subject to their licences.

11. Updates and availability

Updates may address security, compatibility, law or features and may be required for online functions. We aim for reliability but do not promise uninterrupted, error-free or permanent availability. Features may be suspended for maintenance, security, legal or operational reasons. If a paid service is discontinued, mandatory notice, access, refund or remedies will be provided.

12. Suspension and termination

You may stop using FitnX and delete your account as described at Account and Data Deletion.

We may reasonably restrict access for material breach, security threats, fraud, unlawful conduct, non-payment, provider restrictions or legal requirements. Where appropriate and required, we will provide notice and an opportunity to remedy or appeal. Provisions intended to survive termination remain effective.

13. Privacy and export

The Privacy Policy explains data processing, health/location data, providers, retention, export and deletion. Export data you want to keep before account deletion.

14. Warranties and statutory rights

FitnX is provided with reasonable care and skill. Except for express promises and non-excludable rights, it is provided as is and as available. We do not warrant specific fitness outcomes, perfect sensor accuracy, uninterrupted synchronization or permanent third-party availability.

Nothing excludes statutory guarantees, conformity remedies or other mandatory consumer rights.

15. Liability

Nothing excludes or limits liability where unlawful, including for death or personal injury caused by negligence, fraud, wilful misconduct or breach of mandatory consumer law.

Subject to that rule, we are not responsible to the extent loss is caused by unsafe or unlawful use, ignored warnings, inaccurate user input, unsupported devices, third-party outages or events outside reasonable control. For consumers, no additional monetary cap applies beyond limitations permitted by governing mandatory law. For business use, aggregate liability is limited to the amount paid for the Service in the 12 months preceding the event, except where such limitation is unlawful.

16. Business or unlawful use

To the extent permitted by law, a business user or person materially breaching the acceptable-use rules is responsible for third-party claims and reasonable costs caused by that use or breach, except to the extent caused by us. This does not apply where prohibited by consumer law.

17. Governing law and disputes

Hungarian law governs these Terms, without depriving consumers of mandatory protections available in their country of residence. The courts competent for our registered office have jurisdiction, except where mandatory law allows proceedings elsewhere.

Contact support@fitnx.app first. We answer written consumer complaints within 30 days where Hungarian law applies. Hungarian consumers may contact the Pest County Conciliation Board, 1055 Budapest, Balassi Bálint utca 25., 4th floor 2; postal address 1364 Budapest, Pf. 81; pmbekelteto@pmkik.hu; panaszrendezes.hu. We cooperate with conciliation proceedings as required by Hungarian law, without making a general submission beyond mandatory duties.

The competent consumer-protection authority is the Pest County Government Office, Consumer Protection Department, 1072 Budapest, Nagy Diófa utca 10–12., fogyved@pest.gov.hu. The former EU Online Dispute Resolution Platform closed on 20 July 2025 and is not linked.

18. Changes

We may update these Terms for legal, security, provider or product changes. We will post the new date and provide advance notice of material changes where required. Changes do not retroactively remove accrued rights, and continued use does not replace consent where consent is legally required.
