Before using the Service, the User is required to read these Terms and the Privacy policy. Using the Service means accepting these Terms.

§ 3. Services provided electronically and conclusion of the Agreement

Within the Service the Provider offers, free of charge:

• access to informational and educational content (offer pages, district pages, blog, FAQ, reviews),
• the Contact form for sending an enquiry and leaving a phone number for a call back,
• Calculators - a calorie calculator and a fat-loss pace calculator,
• access to individually shared, password-protected materials (e.g. reports prepared for a client).

Using the Service requires neither registration nor an account.

The agreement for access to content and for the Calculators is concluded when the relevant page of the Service is opened and ends when it is left. The agreement for the Contact form is concluded when the form is submitted and ends once the enquiry has been handled.

The User may stop using the services at any time and without giving a reason, simply by leaving the Service. Doing so involves no costs.

The Provider may develop, change and withdraw individual features of the Service. A change may not involve any cost for the User. If a change significantly and negatively affects access to a service, the Provider will announce it in the Service before it takes effect.

§ 4. Technical requirements and security

Proper use of the services requires all of the following:

• an internet connection,
• a device capable of accessing the internet,
• an up-to-date web browser with JavaScript and cookies enabled,
• an active phone number or e-mail address - when using the Contact form.

The Provider applies cryptographic protection of data transmission (HTTPS) as well as logical, organisational and technical measures aimed at preventing third-party access to transmitted data.

Despite the safeguards referred to in section 2 above, using the internet and services provided by electronic means may expose the User's device to malicious software or to third-party access to data stored on it. To minimise this risk the Provider recommends using antivirus software and keeping software up to date.

Within the Service it is prohibited to:

• use viruses, bots, worms or other computer code, files or programs, in particular scripts and applications automating processes,
• automatically download the Service's content in bulk (scraping) without the Provider's prior consent,
• take actions that place an excessive load on the Service's infrastructure,
• attempt to circumvent the Service's safeguards, including gaining unauthorised access to password-protected materials,
• supply unlawful content.

The User is required to provide only data that is true. The Provider is not liable for the consequences of untrue or incomplete data, in particular for being unable to call back.

The Provider strives to keep the Service available at all times but reserves the possibility of technical interruptions.

§ 5. Contact form

Submitting the Contact form requires a first name and a phone number. Providing an e-mail address, a training goal and a message is optional.

To use the Contact form the User should:

• open the contact page of the Service,
• fill in the required fields,
• read these Terms and the Privacy policy,
• click the "Send & book a call" button.

The Contact form serves only to ask a question or book a free consultation. Submitting it is neither an order for training services nor the conclusion of an agreement for such services.

If the User goes to the Contact form straight from a Calculator, the message field may be pre-filled with the results (e.g. starting and target body weight or estimated energy requirements). The User may edit or delete them before sending.

The message should not contain information that is not needed to book a consultation, in particular detailed health information or medical records.

Supplying unlawful content through the Contact form is prohibited.

The Provider responds to enquiries without undue delay, during the working hours shown on the contact page of the Service.

§ 6. Calculators

The Service provides a calorie calculator and a fat-loss pace calculator. The calorie calculator estimates the basal metabolic rate using the Mifflin-St Jeor equation, total energy expenditure and a macronutrient split. The fat-loss pace calculator estimates the time needed to reach a target body weight.

The results are estimates and serve information and education purposes only. They are not dietary or medical advice, nor a nutrition plan, and they do not account for individual health, medication, pregnancy, breastfeeding or chronic conditions.

Calculations run in the User's browser. The data entered (sex, age, height, body weight, activity level) is neither sent to the Provider nor stored in the Service, unless the User sends the result through the Contact form or uses the share-result feature.

Consulting a doctor or a dietitian is recommended before changing your diet or starting a fat-loss phase.

§ 7. Nature of the content and health disclaimer

Content published in the Service, in particular blog articles, service descriptions and videos, is for information and education only and does not constitute medical, physiotherapy or dietary advice.

Consulting a doctor is recommended before starting training - especially with health problems, during pregnancy, after an injury or after a long break from activity.

Prices shown in the Service are indicative and do not constitute an offer within the meaning of Art. 66 of the Polish Civil Code. Terms of training collaboration are agreed individually during a free consultation; the agreement for training services is not covered by these Terms.

Training results depend on individual factors, including health, starting fitness level, nutrition, sleep and consistency. The Provider does not guarantee any specific result, and the case descriptions and Reviews published in the Service are not a promise of the same outcome.

The Service's content is accurate as at its publication date. The Provider updates it where possible but does not warrant that every item reflects the latest state of knowledge.

§ 8. Reviews and User content

The Reviews published in the Service come from the Provider's Google business profile and were written by people who used the Provider's services.

The Provider ensures that published Reviews are genuine as follows:

• every Review links to its original on Google Maps, where its full text, author and date can be verified,
• no invented, purchased or commissioned Reviews from people who have not used the Provider's services are published,
• the Provider neither offers nor accepts payment for writing a Review and does not remove negative Reviews from the Google business profile.

Reviews may be shortened in the Service - only by omitting fragments, without changing their meaning or rating. Authors' surnames are shortened to an initial to limit the personal data published. The full text and signature remain available on Google.

Client video statements are published on the basis of their consent, covering the use of their image. Consent may be withdrawn at any time, in which case the material is removed from the Service.

The User may send the Provider a Review, in particular by e-mail. Sending a Review does not oblige the Provider to publish it. Publication follows agreement with the author on the scope of data published, and a published Review may be removed at the author's request or on the Provider's initiative.

It is prohibited to send Reviews or other User content that:

• contains untrue data or is contrary to law, these Terms or good practice,
• serves activities prohibited by law, incites violence or hatred, or insults a person or group of people,
• may infringe personal rights, copyright, the right to one's image or other third-party rights,
• contains advertising, promotional, political, religious or discriminatory content,
• promotes activity competing with the Provider.

Sending User content or a Review constitutes a statement that the User is its sole author and bears responsibility for the consequences of its publication.

Anyone who believes that content published in the Service (including a Review) breaches the law, these Terms or their rights may report it to trener@tekieli.pl. The report should contain:

• the exact page address and an indication of the content concerned,
• the reasons why the content breaches the law, these Terms or the reporter's rights,
• the reporter's name or company name and e-mail address.

The Provider confirms receipt of the report, examines it within 14 days and notifies the reporter of the decision with reasons. If the report is incomplete, the Provider may ask for it to be completed within 14 days; failing that, the report may be left unexamined. The decision may be appealed to the same address within 14 days of receiving it. Appeals are examined by the Provider and are not handled by automated means without human involvement.

§ 9. Complaints - Consumers and Entrepreneurs with Consumer rights

This paragraph applies only to Consumers and Entrepreneurs with Consumer rights.

A service supplied to the User must conform with the Agreement throughout the period of supply. The Provider is liable for any Lack of conformity revealed during that period.

Where a Lack of conformity appears, the User may lodge a complaint requesting that the service be brought into conformity with the Agreement. Complaints are lodged by e-mail, to the address indicated in § 1(3)(1) of these Terms.

The complaint should contain:

• the User's first name and surname,
• an e-mail address,
• a description of the Lack of conformity,
• a request to bring the service into conformity with the Agreement.

The Provider replies to the complaint by e-mail within 14 (fourteen) days of receiving it. In the reply the Provider:

• accepts the complaint and indicates the planned date for bringing the service into conformity with the Agreement,
• refuses to bring the service into conformity where this is impossible or would require the Provider to incur excessive costs, or
• rejects the complaint as unfounded.

Where the complaint is accepted, the Provider brings the service into conformity with the Agreement at its own cost, within a reasonable time and without significant inconvenience to the User, taking into account the nature of the service and the purpose for which it is used.

Services in the Service are free of charge, so the right to demand a price reduction does not apply. If bringing the service into conformity is impossible or would require excessive costs, if the Provider has failed to bring it into conformity, if the Lack of conformity persists or is significant enough to justify withdrawal without a prior request, the User may withdraw from the Agreement. The declaration of withdrawal may be sent by e-mail, to the address indicated in § 1(3)(1) of these Terms.

Pursuant to Art. 34(1a) of the Consumer Rights Act, after withdrawing from the Agreement the User is obliged to stop using the service and to stop making it available to third parties.

§ 10. Complaints - Entrepreneurs

This paragraph applies only to Entrepreneurs, excluding Entrepreneurs with Consumer rights.

Where a service does not conform with these Terms, the User may lodge a complaint in writing or by e-mail, to the address indicated in § 1(3) of these Terms, no later than 30 days from the day the non-conformity was revealed.

The complaint should contain:

• the User's name,
• an e-mail address,
• a description of the service's non-conformity with these Terms.

The Provider may refuse to bring the service into conformity with these Terms where this is impossible or would require excessive costs.

The Provider replies to the complaint by e-mail within 21 (twenty-one) days of receiving it. In particularly complex cases the reply period may extend to 30 calendar days.

§ 11. Right of withdrawal

Pursuant to Art. 27 et seq. of the Consumer Rights Act, a Consumer and an Entrepreneur with Consumer rights may withdraw from the Agreement without giving any reason within 14 (fourteen) days of its conclusion.

The right of withdrawal is exercised by submitting a declaration of withdrawal to the Provider. Sending the declaration before the deadline expires is sufficient to meet it.

The declaration may take any form, in particular an e-mail or the form set out in Annex 2 to the Consumer Rights Act. The Provider confirms its receipt by e-mail without undue delay.

As the services are free of charge, withdrawal involves no settlements or costs. An effect equivalent to withdrawal also occurs when the User simply stops using the Service.

At the User's request the Provider deletes the User content they sent and their personal data - to the extent and on the terms described in the Privacy policy.

§ 12. Liability

The Provider undertakes to provide the services with due care.

The Provider does not guarantee uninterrupted and error-free availability of the Service. Maintenance work is carried out in the least disruptive manner possible, and the Provider gives advance notice of planned work where possible.

To the extent permitted by the Polish Civil Code and the Consumer Rights Act, the Provider is not liable for the consequences of:

• using the services contrary to their purpose or to these Terms,
• the User providing incorrect or untrue data,
• training, nutrition or health decisions taken solely on the basis of the Service's content or Calculator results, without consulting a doctor or another specialist,
• sharing the password to password-protected materials with third parties.

To the extent permitted by the Polish Civil Code and the Consumer Rights Act, the Provider is not liable for disruptions to the Service resulting from:

• force majeure,
• maintenance work,
• causes attributable to the User, including their device, software or internet connection,
• causes beyond the Provider's control, in particular acts of third parties and failures of hosting, e-mail and network providers.

The Service links to third-party websites, including Google Maps and social media. The Provider is not responsible for their content or for the rules on which they are run.

The parties exclude the Provider's liability for lost profits of a User who is an Entrepreneur.

The limitations of liability set out in this paragraph do not apply to Consumers and Entrepreneurs with Consumer rights to the extent that the law does not permit their exclusion or limitation, nor to damage caused intentionally.

§ 13. Intellectual property

All elements of the Service, in particular:

• the name and logo of the Service,
• texts, blog articles, service descriptions and FAQ,
• photos, videos and graphic elements,
• the layout and composition of pages, the interface, the source code and databases

- are protected under the Polish Act of 4 February 1994 on copyright and related rights, the Act of 30 June 2000 on industrial property law, the Act of 16 April 1993 on combating unfair competition and other generally applicable law, including European Union law.

Any use of the Provider's intellectual property without prior, explicit permission is prohibited. This does not apply to permitted use, in particular the right of quotation - provided the author and source are indicated and a link to the page the material comes from is included.

The Provider reserves the Service's content from text and data mining, including the training of artificial intelligence models, without prior consent. This constitutes a reservation of rights within the meaning of the provisions on permitted use for text and data mining.

Photos from external sources carry a caption naming the author and the source; the rights to them belong to their owners and they are not covered by section 1 above.

§ 14. Out-of-court dispute resolution

This paragraph applies only to Consumers and Entrepreneurs with Consumer rights.

The User may use out-of-court means of handling complaints and pursuing claims. Using them is voluntary and requires the consent of both parties.

Detailed information about the available procedures and how to access them is available at the offices and on the websites of:

• district (municipal) consumer ombudsmen and social organisations whose statutory tasks include consumer protection,
• Provincial Inspectorates of Trade Inspection, including the permanent consumer courts and mediation proceedings run by them,
• the Polish Office of Competition and Consumer Protection (uokik.gov.pl).

§ 15. Personal data and cookies

Information about the processing of Users' personal data and about the use of cookies and browser storage is set out in the Privacy policy, available at trener.tekieli.pl/en/privacy-policy.

The decision on analytics cookies can be changed at any time via the "Cookie settings" link in the footer of the Service.

§ 16. Amendments to the Terms

The Provider may amend these Terms in the event of:

• a legal obligation to make changes, including aligning the Terms with the current law,
• a change to the scope or manner of providing the services, the launch of new services or the discontinuation of existing ones,
• a technical modification of the Service requiring the Terms to be adjusted,
• a change of the Provider's details or of the providers of tools used in the Service.

Users are informed of amendments by publication of the amended Terms in the Service, together with the date from which they apply.

Agreements concluded before an amendment are governed by the Terms in force on the day they were concluded.

A User who does not agree to an amendment may stop using the Service and, as regards an ongoing service (the handling of a submitted enquiry), terminate the Agreement with immediate effect within 10 (ten) days of publication of the amended Terms. The declaration of termination may be sent by e-mail, to the address indicated in § 1(3)(1) of these Terms.

Changes to the training offer and its prices do not constitute an amendment to these Terms.

§ 17. Final provisions

The current version of these Terms has been in force since 21 August 2026. Earlier versions are made available by the Provider on request sent by e-mail.

These Terms are governed by Polish law. The choice of Polish law does not deprive a Consumer of the protection afforded by the mandatory provisions of the law of their country of habitual residence.

The parties will seek to resolve any dispute amicably. Failing agreement, the dispute is heard by a common court - for Consumers and Entrepreneurs with Consumer rights, the court having jurisdiction under general rules, and for other Entrepreneurs, the court having jurisdiction over the Provider's place of business.

If any provision of these Terms proves invalid or ineffective, the remaining provisions stay in force.

Matters not covered by these Terms are governed by Polish law, in particular the Civil Code, the E-Services Act, the Consumer Rights Act and data protection regulations.
