Terms of Use

These Terms of Use describe the conditions that apply when you access or use the RPE Calculatr website, its public calculator, and its published resources. Your use of the website is subject to these Terms and to rights and obligations that cannot be excluded under applicable law.

Continuing to use the website after having a reasonable opportunity to review these Terms indicates that you intend to use the service subject to them. This statement does not create a consent mechanism beyond the notices and controls actually presented on the website. If you disagree with these Terms, you should discontinue use of the service.

RPE Calculatr provides resources associated with strength training. These may include an online RPE calculator, explanations of Rate of Perceived Exertion and Reps in Reserve, training-related articles, and other functionality that is actually made available through the website.

The calculator may process training details entered by a visitor to provide relevant estimates. The precise inputs and outputs available are those displayed in the live calculator. References in these Terms do not promise that a particular feature will always be present.

Services may evolve as content, calculation methods, technical systems, and user needs change. Features may be introduced, improved, limited, replaced, or removed, subject to applicable law and any express commitments associated with a service.

You may access the website only in a manner that complies with laws and regulations applicable to you. The public calculator is intended to be usable without account registration unless the website expressly states otherwise for a separate feature.

These Terms do not establish a minimum age because no verified age requirement has been supplied for publication. If local law requires parental involvement or limits a person's ability to use online services, those requirements continue to apply. Any planned minimum-age rule should be confirmed by the operator and legal counsel before being added.

When using RPE Calculatr, you are responsible for:

• Providing accurate and complete calculator inputs.
• Interpreting results in light of your experience, abilities, and circumstances.
• Exercising reasonable judgment when choosing training loads and exercises.
• Following applicable laws and respecting the rights of other people.
• Avoiding misuse of the website or attempts to interfere with its functionality.

Incorrect, incomplete, or unrealistic input data can produce misleading estimates. You should review your entries and should not treat an output as a substitute for practical judgment, safe technique, or appropriate professional advice.

You may use the public website, calculator, reference material, and articles for lawful personal and educational purposes. Ordinary browsing, sharing links to public pages, and using calculator results for personal training planning are generally acceptable.

Any use must remain consistent with these Terms, applicable law, reasonable technical limits, and the rights of others. Permission to access the website does not transfer ownership of its protected content or authorize commercial copying, republication, or the creation of a competing content database.

You must not use the website to:

• Attempt unauthorized access to systems, data, accounts, or restricted areas.
• Upload, transmit, or distribute malware or other harmful code.
• Disrupt, overload, degrade, or interfere with website operation or security.
• Circumvent reasonable technical restrictions or access controls.
• Engage in impersonation, fraud, unlawful conduct, or abusive communications.
• Misuse contact forms through spam, harassment, or deceptive submissions.
• Infringe intellectual-property, privacy, or other rights belonging to third parties.
• Use automation at a volume or in a manner that materially harms availability.

This section is not intended to prohibit ordinary browsing, accessibility tools, or legitimate search-engine indexing that respects applicable technical instructions and does not harm website security or availability.

RPE calculator outputs are estimates derived from information supplied by the user and the calculation model used by the website. Relevant inputs may include weight lifted, repetitions completed, and a self-reported Rate of Perceived Exertion. Where supported by the live calculator, outputs may include estimated one-repetition maximum, Reps in Reserve, or suggested training-load estimates.

Actual performance may differ because of fatigue, technique, training experience, exercise selection, individual physiology, recovery, inaccurate input information, and inherent limitations in prediction models. A self-reported RPE is subjective and can become more consistent with experience, but it is not an objective measurement.

Estimates may be more or less useful depending on the exercise and training context. RPE Calculatr does not guarantee calculation accuracy, personal records, strength gains, or any particular training outcome.

Content on RPE Calculatr is intended for general information and education. It is not individualized medical advice, diagnosis, treatment, rehabilitation guidance, or a personalized exercise prescription.

Exercise and strength training carry inherent risks. Select exercises and loads appropriate to your abilities, prioritize correct technique, use suitable equipment, and progress reasonably. Factors such as health history, injury status, medication, training environment, and supervision can affect what is appropriate for an individual.

Original written content, branding, website design, graphics, and software components made available through RPE Calculatr may be protected by copyright, trademark, and other intellectual-property laws. Subject to these Terms, visitors may view and use public content for ordinary personal and educational purposes.

Unless permission or applicable law allows otherwise, protected material should not be copied, republished, sold, systematically extracted, or redistributed in a way that substitutes for the website or misrepresents its source.

RPE Calculatr does not claim ownership of publicly available mathematical formulas, third-party icons, open-source components, licensed assets, or other third-party material beyond the rights actually held or licensed. Those materials remain subject to their respective rights and license conditions.

Website pages may link to external websites, tools, research, or other resources for convenience or additional context. Third-party services operate independently and may have different content, availability, security practices, and legal policies.

A link does not automatically constitute endorsement, sponsorship, or a partnership. Before relying on an external resource or providing it with information, review its current terms, privacy notices, and other relevant policies.

The information supplied for these Terms indicates that the website currently provides a free public calculator and does not confirm an active checkout or paid subscription system. Accordingly, these Terms do not claim that a subscription can presently be purchased and do not invent renewal, cancellation, refund, tax, or payment-processing terms.

If paid services launch, the applicable price, payment method, billing period, renewal status, cancellation process, refund position, taxes, fees, and any service-specific conditions should be disclosed before a purchase is completed. Those commercial terms must be confirmed before publication or launch.

The website may occasionally be unavailable because of maintenance, updates, security work, hosting interruptions, network conditions, technical faults, or other operational limitations. No uninterrupted-access or uptime commitment is made unless one is expressly provided in a separate written agreement.

Features and calculation methods may be improved, modified, limited, replaced, or discontinued. Where a change affects a paid or separately agreed service, any applicable contract and mandatory consumer rights will continue to govern.

To the extent permitted by applicable law, RPE Calculatr's public information and services are provided on an “as available” basis, subject to any express commitments made by the operator. No guarantee is made that estimates will be exact, that every page will be continuously available, or that the website will be compatible with every device, browser, or configuration.

Fitness information, technical functionality, and third-party resources may contain limitations or errors. Nothing in these Terms excludes warranties, remedies, or statutory protections that cannot lawfully be excluded or restricted.

To the extent permitted by applicable law, responsibility for losses connected with reliance on calculator estimates, use of general training information, website interruptions, technical errors, or third-party services may be limited where the loss was not reasonably attributable to a breach of an applicable legal duty or an express commitment.

The scope and enforceability of any limitation depend on the governing law and the circumstances. These Terms do not exclude or restrict responsibility for fraud, willful misconduct, gross negligence, death or personal injury where such exclusion is prohibited, or any other liability that cannot lawfully be limited.

Legal review required: A jurisdiction-specific liability clause should be finalized after the operator's legal identity and governing law are confirmed.

Subject to applicable law, a user may be responsible for reasonably documented losses directly resulting from that user's unlawful conduct or material breach of these Terms, such as a deliberate security attack or infringement of another person's rights.

This provision is not intended to impose responsibility for losses unrelated to the user's conduct, to override mandatory consumer protections, or to create an unlimited indemnity. Its applicability and enforceability depend on relevant law.

Last Updated: 25 October 2026

These Terms may be revised when services, legal requirements, or operational practices change. Updated terms will be published on this page with a revised “Last Updated” date.

No personal email notification is promised unless a notification process is expressly introduced. Whether and how a change applies depends on applicable law, the nature of the change, and any separate agreement governing a service.

The operator may take proportionate steps to restrict access associated with a security threat, serious misuse, unlawful conduct, an attempt to disrupt the website, or a material violation of applicable terms. Measures may include blocking harmful traffic or limiting access to affected functionality.

This section does not invent an account-deletion process where no account system exists. Any restriction affecting a future paid service must also respect the relevant agreement and mandatory consumer rights.

These Terms therefore do not select a jurisdiction, court location, arbitration system, or class-action waiver. Any finalized dispute provision should preserve mandatory consumer rights and access to remedies that applicable law requires.

Where appropriate, parties may first attempt to resolve a concern through direct communication, but this does not remove any legal right to use an available court, regulator, or other lawful dispute process.
