Terms of Service

Effective date: October 18, 2026

These Terms of Service ("Terms") are the agreement between you and for the use of GymNavi. They also set out the rules for the services we provide to you electronically. Please read them together with our Privacy Policy, Refunds and Money-Back Guarantee and Cookie Policy. These Terms are available free of charge at https://gymnavi.app in a form you can download, save and print.

The short version

• GymNavi is an AI fitness coach, not a doctor. Talk to a doctor before you start, especially if you have an injury or a health condition, and stop if something hurts.
• Subscriptions renew automatically until you cancel. You can cancel at any time and keep access until the end of the period you have paid for.
• All web Subscription payments made in your first 30 days are covered by our money-back guarantee, and in your first 14 days you can withdraw in Settings and get everything back.
• If you buy in the iOS or Android app, Apple or Google handles billing and refunds under its own rules.
• You must be at least 16 to use GymNavi.
• If you are a consumer, nothing in these Terms limits the rights you have under the mandatory law of your country.

1. Who we are

GymNavi is provided by , , tax ID ("we", "us", "our"). You can contact us at any time at contact@gymnavi.app. Our website is https://gymnavi.app.

2. Definitions

• Service — GymNavi, available as a web app at https://gymnavi.app and as iOS and Android apps, with all of its features.
• Account — your personal GymNavi account, created with your email address.
• Subscription — paid, automatically renewing access to the Service for a weekly, monthly or yearly billing period.
• AI pack — a one-off purchase of additional AI usage on top of the allowance included in your Subscription.
• Consumer — an individual using the Service for purposes outside their trade, business or profession. Under Polish law, consumer protection also covers a sole trader who concludes a contract directly related to their business when the contract is not of a professional nature for them.

3. What GymNavi does

GymNavi is a digital fitness service. It includes:

• a personal training plan that generates workouts and adjusts weights and repetitions based on your questionnaire answers, your training history and how you rate your workouts;
• an AI coach you can chat with;
• food logging, including AI analysis of photos of meals and nutrition labels, and barcode lookups in the Open Food Facts database;
• progress photos, stored privately, with optional AI comparison;
• strength ranks, weekly reports, streaks, reminders and notifications;
• a referral program.

Taking the questionnaire, seeing your plan preview and having an Account are free. Full access to the Service requires an active Subscription. We show each plan's price and billing period before you buy.

4. Health and safety — please read this

GymNavi gives general fitness and nutrition guidance. It is not medical advice and not a medical device. It does not diagnose, treat, cure or prevent any disease, and it does not replace a doctor, physiotherapist, dietitian or qualified trainer who can assess you in person.

• Check with a doctor before you start, especially if you have an injury or pain, a heart or blood pressure condition, diabetes, are pregnant or have recently given birth, take medication, have a history of eating disorders, or have not exercised for a long time.
• Stop immediately if you feel pain, dizziness, chest pain, unusual shortness of breath or otherwise unwell, and seek medical help if needed. In an emergency, call your local emergency number (for example 112 in the EU, 999 in the UK or 911 in the US).
• AI can be wrong. Suggested workouts, weights, chat answers and photo analyses are generated automatically and may be inaccurate or unsuitable for you. Use your own judgement: if a weight or exercise feels too hard or unsafe, choose a lighter option or skip it.
• Nutrition numbers are estimates. Calories and macronutrients from photos, labels and product databases are approximations. Do not rely on GymNavi for medical diets, allergies or intolerances — always check the product label.
• You are responsible for exercising safely: warming up, using correct technique, using equipment as intended and checking that it is in good condition, using a spotter or safety equipment for heavy lifts, and training in a safe place.
• Injuries and limitations. If you tell us about injuries or limitations, we use this to adapt your plan, but we cannot guarantee that every exercise suits your condition.

5. Who can use GymNavi

You must be at least 16 years old to use the Service. If you are under 18 (or under the age of majority where you live), you may buy a Subscription or AI pack only with the consent of a parent or legal guardian.

6. Your Account

You create your Account by completing the questionnaire on our website and giving us your email address and first name. This concludes an agreement with us for the Account service, which is free of charge and runs for an indefinite period.

• Give us accurate information and update it when it changes — your plan depends on it.
• Your Account is personal. Do not share it or let others use it.
• Keep your email account and devices secure, and tell us at contact@gymnavi.app if you think someone has accessed your Account without permission.

You can end this agreement at any time by deleting your Account in Settings. This permanently deletes your data as described in our Privacy Policy.

7. Technical requirements and risks

To use the Service you need:

• an internet connection and an active email address;
• for the web app: a current version of Chrome, Safari, Firefox or Edge with JavaScript and cookies enabled;
• for the mobile app: a device running a version of iOS or Android supported by the app, as stated in the App Store or Google Play listing;
• optionally, a camera for food and progress photos, and notifications enabled if you want reminders.

Like any online service, using GymNavi involves general risks such as malware, phishing or unauthorised access to your device or email. Protect yourself with up-to-date software and a secure email account. We will never ask for your password or payment card details by email.

8. Subscriptions and payments

Where you buy

• On the web, payments are processed by Stripe and you buy from us. You choose a plan, tick the required box "I want my plan to start immediately. I understand that my subscription renews automatically every week/month until I cancel." and press Subscribe and pay. The Subscription contract is concluded when your payment is confirmed. We then send you a welcome email confirming your plan and billing period, automatic renewal, how to cancel, your request to start immediately, your 14-day right of withdrawal and our money-back guarantee.
• In the iOS or Android app, you buy through the Apple App Store or Google Play. The store charges you, and its terms of sale, billing and refund rules apply to that purchase.

Prices and taxes

The price, currency, billing period and renewal price are shown before you pay. Prices for consumers include VAT where applicable. In some places (for example some US states), sales tax may be added and shown before you confirm the payment. If we offer an introductory price, we clearly show what you will pay after the introductory period.

Automatic renewal

Your Subscription renews automatically at the end of each billing period, and we (or the store) charge the renewal price to your payment method until you cancel.

Price changes

We may change Subscription prices for future billing periods for valid reasons, such as changes in our costs (for example AI or hosting fees), taxes or the scope of the Service. We will tell you by email or in the app at least 30 days before a new price applies to you. If you don't agree, you can cancel before the change takes effect. A new price never applies to a period you have already paid for.

Failed payments

If a renewal payment fails, we or the store may try again. If payment still cannot be collected, access to paid features ends until the payment is made.

AI packs

AI packs are one-off purchases and do not renew. Before buying, you tick a required box agreeing to immediate delivery and acknowledging that you lose the right of withdrawal for the pack once it is delivered. The extra AI usage is added to your Account right after purchase, is used once your monthly allowance runs out, and carries over to the following months. It has no cash value and expires when your Account is deleted.

Receipts and invoices

We send a payment confirmation by email. If you need an invoice, write to contact@gymnavi.app.

9. Cancelling your Subscription

You can cancel at any time. Cancelling stops future renewals; you keep access until the end of the billing period you have already paid for. We don't refund the rest of a period when you cancel, unless you withdraw within 14 days, use our money-back guarantee or are otherwise entitled to a refund by law (see section 10).

• Web Subscription: go to Settings and choose Manage subscription, which opens our secure customer portal run by Stripe. You can also email us at contact@gymnavi.app.
• App Store or Google Play Subscription: cancel in your Apple ID or Google Play subscription settings. We cannot cancel store subscriptions for you.

Deleting your Account immediately cancels a web Subscription and ends your access; it does not by itself give a refund. It does not cancel an App Store or Google Play Subscription, so please cancel that in the store first.

10. Right of withdrawal and money-back guarantee

• Right of withdrawal. You can withdraw from a web Subscription within 14 days of the day it starts, without giving a reason, by pressing Withdraw from contract in Settings or by emailing contact@gymnavi.app. Your Subscription ends immediately and we refund all of its payments in full. Although you asked us to start immediately, we do not charge for the days you used. A new Subscription taken out later is a new contract with its own 14 days. This is a statutory right for consumers in the EU and UK, and we give it to every customer who buys on our website.
• AI packs. You lose the right of withdrawal for an AI pack once it is delivered, as you agree at checkout. We still refund a completely unused pack if you email us within 14 days.
• Money-back guarantee. All web Subscription payments made within 30 days of your first payment are covered by our money-back guarantee. Just email contact@gymnavi.app within that time. The guarantee applies once per person.
• App Store and Google Play. Refund and withdrawal requests for store purchases go through the store.

Full details, including a model withdrawal form, are in our Refunds and Money-Back Guarantee policy.

11. AI features and fair use

• You are interacting with AI. The AI coach and other AI features are automated systems, not humans, and their output may be wrong (see section 4).
• Fair-use allowance. Each Subscription includes a monthly AI usage allowance that covers normal personal use and renews every 30 days. If you reach it, AI features such as the coach chat and photo analysis pause until the next period, unless you buy an AI pack. Your training plan and workout logging keep working.
• Proper use. Use AI features only for your own fitness and nutrition. Don't try to get around usage limits or extract the AI's instructions, and don't use the features to create unlawful or harmful content.

12. Referral program

You can invite friends with your personal referral link or code.

• When a friend signs up with your link or code and makes their first payment, you and your friend each receive account credit worth the price of one month of the monthly plan, in the currency of your Subscription. Credit is applied automatically to your next web payments. If you subscribe through the App Store or Google Play, you get one free month of access instead, because store payments cannot be credited.
• Referred friends must be new customers. You can't refer yourself or use extra accounts or email addresses.
• Credit has no cash value and can't be transferred or exchanged for money.
• If the friend's first payment is refunded, the related rewards may be cancelled. We may also withhold or cancel rewards obtained through fraud, spam or other abuse.
• Share your link only with people who are happy to receive it.
• We may change or end the program for the future. Rewards already earned remain valid.

13. Your content

Your content is what you add to the Service: questionnaire answers, workout logs and ratings, food logs, measurements, photos and chat messages.

• You keep all rights to your content.
• You allow us to store and process your content only as needed to provide and improve the Service for you, as described in our Privacy Policy. This permission ends when you delete the content or your Account, except where the law requires us to keep something.
• Progress photos are private. Only you can see them in the app. They are analysed by AI only when you use the comparison feature.
• If you photograph the nutrition label of a product our databases don't know, we may save that product's nutrition values (not your photo or any information about you) so other users can find the product too.

14. Acceptable use

You must use GymNavi in line with the law, these Terms and good practice. In particular, you must not:

• provide unlawful content or content that infringes the rights of others, or is offensive, threatening or sexually explicit — including in photos and chat messages;
• upload photos of other people without their permission;
• try to access other users' data or our systems without permission, or interfere with the security or operation of the Service;
• use bots, scrapers or other automated tools to access the Service, or resell or share access to it;
• use the Service in a way that could harm us, other users or anyone else.

15. Our intellectual property

The Service, including its software, design, texts, training logic and brand, belongs to us or our licensors and is protected by law. We give you a personal, non-exclusive, non-transferable right to use the Service for your own non-commercial purposes while you have an Account. Exercise videos are provided under licence from MuscleWiki. Product data from Open Food Facts is available under the Open Database License (ODbL).

16. Availability, updates and changes

We aim to keep GymNavi available at all times, but there may be interruptions for maintenance, updates or reasons outside our control.

We provide updates, including security updates, needed to keep the Service working as described. We may also change the Service for valid reasons, such as improving features, security, adapting to new technology or legal requirements, or changes made by our providers. Such changes cost you nothing extra. If a change significantly and negatively affects your access to or use of the Service, we will tell you in advance, and you may end your Subscription free of charge within 30 days of being informed or of the change (whichever is later), with a refund for the unused part of any prepaid period.

17. Our responsibility for the Service and complaints

We are responsible for providing the Service in line with the contract. If you are a consumer and the Service does not conform to the contract, you have statutory rights, including the right to have it brought into conformity and, in some cases, to a price reduction or to end the contract. These rights apply for as long as we provide the Service to you.

How to complain. If something doesn't work or you are unhappy with the Service, write to contact@gymnavi.app and include:

1. your Account email address;
2. a description of the problem and when it started;
3. what you would like us to do.

We will reply within 14 days of receiving your complaint. If you are a consumer in Poland and we do not reply within that time, your complaint is treated as accepted.

18. Liability

• Consumers: we are liable in line with the mandatory law of your country. Nothing in these Terms excludes or limits our liability for intentional harm or gross negligence, for death or personal injury caused by our negligence, for fraud, or affects your statutory consumer rights.
• Matters outside our responsibility: to the extent permitted by law, we are not responsible for harm resulting from ignoring the health and safety guidance in section 4, from improper use of equipment, from inaccurate information you give us, or from events beyond our reasonable control. Third-party services, such as the app stores, are governed by their own terms.
• Business users: if you use GymNavi other than as a consumer, our total liability is limited to the amount you paid us in the 12 months before the claim, and we are not liable for lost profits or indirect losses, except where the law does not allow such limits.

19. Suspension and termination by us

We may suspend or close your Account if you seriously or repeatedly breach these Terms (for example by providing unlawful content, abusing AI features or the referral program, or endangering the security of the Service), or if the law requires it. Except where immediate action is necessary (for example to stop illegal activity or a security threat), we will first warn you and give you at least 7 days to fix the problem.

If we close your Account or stop offering the Service without your fault, we will refund the unused part of your prepaid period. We will announce the end of the Service at least 30 days in advance.

20. App Store and Google Play

If you use the app downloaded from the Apple App Store or Google Play:

• These Terms are between you and us, not Apple or Google. We, not Apple or Google, are responsible for the app and its content.
• Apple and Google have no obligation to provide maintenance or support for the app.
• If the app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price of the app, if any. To the extent permitted by law, Apple has no other warranty obligation for the app.
• We, not Apple or Google, are responsible for handling claims relating to the app, including product liability claims, claims that the app fails to meet legal or regulatory requirements, consumer protection claims and intellectual property infringement claims.
• You confirm that you are not located in a country subject to a US government embargo and are not on any US government list of prohibited or restricted parties.
• You must also follow the store's terms of use. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

21. Changes to these Terms

We may change these Terms for valid reasons, such as changes to the Service, our payment methods, the law or guidance from authorities. We will notify you by email or in the app at least 14 days before the changes take effect, unless a change is required by law sooner or is only to your benefit. If you don't agree, you can cancel your Subscription and delete your Account before the changes take effect. Changes never apply retroactively.

22. Governing law and disputes

These Terms are governed by Polish law. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring proceedings in the courts of that country. Disputes with business users are decided by the court competent for our registered office.

Out-of-court options. You can also use out-of-court complaint and redress procedures. In Poland, consumers can get free help from their municipal or district consumer ombudsman (rzecznik konsumentów) and can use mediation or the permanent consumer arbitration courts run by the Trade Inspection (Inspekcja Handlowa) — see uokik.gov.pl. Consumers in other EU countries can contact their national consumer bodies and, for cross-border disputes, the European Consumer Centre in their country. Using these procedures is voluntary for both sides.

23. Notes for UK and US users

• UK: nothing in these Terms affects your statutory rights under the Consumer Rights Act 2015 or the Consumer Contracts Regulations 2013. You may bring claims in the courts of the part of the UK where you live.
• US: your Subscription renews automatically until you cancel, and you can cancel online at any time as described in section 9. To the extent permitted by law and except as expressly stated in these Terms, the Service is provided "as is" and "as available", without implied warranties such as merchantability or fitness for a particular purpose. Some states do not allow these exclusions, so they may not apply to you, and you may have additional rights under your state's law.
