Terms of Service

Agreement and service operator

These Terms of Service (the “Terms”) are a binding agreement between you and Effort Signal, the operator of the web service available at effortsignal.com (“Effort Signal,” “we,” “us,” or “our”). They govern your access to and use of the website, applications, APIs, activity analysis, and related features (collectively, the “Service”).

By accessing or using the Service, you agree to these Terms. If you do not agree, do not use the Service. If you use the Service for an organization, you represent that you have authority to bind that organization, and “you” includes the organization.

Eligibility and accounts

You must be at least 18 years old and legally able to enter into this agreement. The Service is not directed to children. You must provide accurate account information, maintain the confidentiality of your credentials, and promptly notify us if you suspect unauthorized access.

You are responsible for activity under your account unless caused by our breach of a duty that applicable law does not allow us to exclude. You may not share an account in a way that defeats access controls or impersonate another person.

The Service and beta status

Effort Signal imports compatible activity files and, where available, connected-provider data; organizes activities; and calculates or displays routes, intervals, training load, heart rate, power, pace, elevation, and other fitness metrics. Available features and outputs depend on the sport, device, sensors, source file, profile settings, and data quality.

The Service is currently offered as a beta. Features, calculations, supported formats, limits, and availability may change. We may correct, add, suspend, or discontinue features when reasonably necessary for product development, security, legal compliance, or operations. We do not promise that every device field, provider export, or historical result will remain compatible forever.

No medical advice or safety monitoring

Effort Signal is not a medical device or healthcare provider. The Service does not diagnose, treat, cure, or prevent any disease and is not a substitute for a physician, qualified coach, or emergency service.

Metrics, zones, estimates, comparisons, and visualizations can be incomplete, delayed, inaccurate, or unsuitable for your circumstances. No feature continuously monitors your condition or can determine whether exercise is safe for you. Do not disregard symptoms or professional advice because of information shown by the Service. Seek urgent medical help when appropriate.

You remain solely responsible for deciding whether, when, and how to train and for using appropriate equipment, supervision, and safety precautions. You assume the ordinary risks of exercise and outdoor activity, except to the extent applicable law places a non-waivable responsibility on us.

Your data and content

You retain ownership of files, routes, profile information, tags, names, and other content you submit or direct a provider to send to the Service (“User Content”). You grant us a non-exclusive, worldwide, royalty-free license to host, store, copy, transform, analyze, and display User Content only as needed to operate, secure, support, and improve the Service for you and to comply with law. This license permits our service providers to process User Content on our behalf for those same limited purposes.

You represent that you have the rights and permissions needed to submit User Content, including data concerning another person. Do not upload unlawful content, malware, or information you are not authorized to process. We do not sell User Content and do not use it for advertising or marketing.

Acceptable use

You may not use the Service to:

• violate law, privacy, intellectual-property, or other rights;
• access another user’s account, files, or data without authorization;
• probe, bypass, disable, or interfere with security, authentication, rate limits, or availability;
• upload malicious code or use automated traffic that unreasonably burdens the Service;
• scrape, resell, sublicense, or commercially exploit the Service except with written permission;
• reverse engineer the Service except where applicable law expressly permits it; or
• misrepresent Service output as a medical diagnosis or guaranteed safety assessment.

We may investigate suspected misuse and take proportionate steps to protect users, the Service, and third parties.

Devices and third-party services

The Service may interoperate with devices, file formats, map tiles, or accounts operated by third parties, including Garmin, Polar, Strava, Wahoo, OpenFreeMap, and Amazon Web Services public Terrain Tiles when those features are available or selected. Their products, terms, privacy practices, data accuracy, outages, and changes are outside our control.

You authorize us to exchange the data necessary to perform an integration you request. You are responsible for maintaining permission to use each connected account. We may disable an integration that becomes insecure, unlawful, unavailable, or incompatible.

Privacy

Our Privacy Policy explains how we handle personal data. Our separate Consumer Health Data Privacy Policy describes health-data practices and rights under applicable U.S. consumer-health laws. Those policies are incorporated into these Terms by reference where applicable.

Availability, retention, and your copies

Keep independent copies of original activity files and any information you cannot afford to lose. Although we use safeguards designed to preserve data, the Service is not an archival or disaster-recovery service, and uninterrupted access or lossless storage is not guaranteed.

Removing an activity through the current product interface hides it from the active library but may preserve its source and derived records for recovery. To request permanent deletion of personal data, follow the process in the Privacy Policy. Residual copies may remain in restricted backups or records we must retain by law.

Suspension and termination

You may stop using the Service at any time. We may suspend or terminate access when we reasonably believe it is necessary to address a material breach, security risk, unlawful conduct, harm to another person, prolonged inactivity, or discontinuation of the Service. Where reasonably possible, we will provide notice and an opportunity to export or request return of your data unless doing so would create a security or legal risk.

Provisions that by their nature should survive termination—including ownership, disclaimers, limitations of liability, dispute provisions, and payment obligations, if any—will survive. Termination does not eliminate privacy rights or our data-protection obligations.

Effort Signal rights and feedback

The Service, including its software, design, branding, documentation, and non-user content, is owned by or licensed to Effort Signal and protected by applicable law. These Terms grant you only a limited, revocable, non-transferable right to use the Service for its intended purpose.

If you voluntarily provide ideas or feedback, you allow us to use them without restriction or compensation, provided that this does not change our obligations regarding personal data contained in the feedback.

Disclaimers

To the maximum extent permitted by law, the Service is provided “as is” and “as available.”

We disclaim all express, implied, and statutory warranties, including merchantability, fitness for a particular purpose, title, non-infringement, accuracy, availability, security, and compatibility. We do not warrant that calculations, sensor data, routes, recommendations, or integrations are complete or error-free; that defects will be corrected; or that the Service will meet your requirements.

Nothing in these Terms excludes a warranty or remedy that applicable consumer law does not allow to be excluded.

Limitation of liability

To the maximum extent permitted by law, Effort Signal and the people and service providers involved in operating it will not be liable for indirect, incidental, special, exemplary, punitive, or consequential damages, or for lost profits, revenue, goodwill, opportunities, data, or use, arising from or related to the Service, even if advised that such loss was possible.

To the maximum extent permitted by law, our total aggregate liability for all claims arising from or related to the Service or these Terms will not exceed the fees you paid directly to Effort Signal for the Service during the three months immediately before the event giving rise to the claim, or the equivalent amount in your local currency.

These exclusions and caps apply regardless of the theory of liability and even if a remedy fails its essential purpose. They do not limit liability for fraud, willful misconduct, gross negligence where it cannot be limited, death or personal injury caused by negligence where it cannot be limited, breach of non-waivable data-protection duties, or any other liability that applicable law prohibits us from excluding. Where a cap is not enforceable, liability is limited to the minimum extent permitted by law.

Indemnity

To the extent permitted by law, you will defend, indemnify, and hold harmless Effort Signal and the people involved in operating it from third-party claims, damages, and reasonable costs arising from your unlawful use of the Service, your material breach of these Terms, or User Content that infringes another person’s rights. This obligation does not apply to the extent a claim results from our own breach, negligence, or misconduct, and it does not reduce non-waivable consumer rights.

Mandatory consumer rights

If you are a consumer, you retain all rights and remedies that the law of your habitual residence makes mandatory. In particular, these Terms do not waive mandatory EU, EEA, UK, or U.S. state consumer protections, statutory conformity rights for digital services, or rights that cannot legally be limited by contract.

If a provision conflicts with mandatory law, it applies only to the maximum lawful extent, and the remainder of these Terms remains effective.

Disputes and applicable law

Before starting formal proceedings, please send a description of the dispute and the requested resolution to legal@effortsignal.com so we can try to resolve it informally. This does not prevent either party from seeking urgent relief or using a small-claims, regulator, consumer-protection, or other process available under applicable law.

These Terms are governed by the law applicable to the operation of Effort Signal, without overriding mandatory rules of your country or state of residence. A dispute may be brought in any court or tribunal that has jurisdiction under applicable law. We do not require an EU or EEA consumer to litigate outside the courts available under mandatory consumer law.

Changes to these Terms

We may update these Terms to reflect changes in the Service, law, security, or operations. We will post the revised version and update its effective date. When a change materially affects your rights, we will provide additional notice where required and will not apply the change retroactively unless law permits it. Your continued use after the revised Terms take effect means you accept them; if you do not agree, stop using the Service.

General terms and contact

These Terms and the policies they incorporate are the entire agreement about the Service. A failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them as part of a reorganization, financing, merger, sale, or transfer of the Service, subject to applicable law. Neither party is liable for delay caused by events beyond reasonable control, except for obligations that cannot lawfully be excused.

Questions about these Terms may be sent to legal@effortsignal.com. Privacy requests should be sent to privacy@effortsignal.com.
