Legal

Terms of service.

These terms govern use of LeanLens and any Pro subscription, including photo eligibility rules, AI estimates, accounts, billing, user responsibility, and mandatory consumer rights.

Updated July 21, 2026
Quick answerLeanLens provides informational, AI-generated fitness estimates—not medical measurements. Free and Pro differ in scan cadence and result depth. Pro is offered only through a supported mobile storefront, renews according to the offer shown at purchase, and must be managed through that storefront.

#Agreement and eligibility

These Terms form an agreement between you and the LeanLens service provider when LeanLens presents them to you and you affirmatively accept them. Merely visiting a public page does not by itself record acceptance. You can review the complete Terms before accepting them. You also acknowledge the Privacy Policy. If you do not agree, do not create an account, request an analysis, or purchase Pro.

Contracting party: LeanLens is the trading name of an independent service provider established in Portugal. Use support@leanlens.ai for privacy, legal, support, and complaint communications.

Eligibility: You must be at least 16 years old to create an account, request an analysis, purchase Pro, or otherwise use LeanLens.

Photos of people aged 16+ and authorization: You may upload only a photo of yourself or another identifiable person aged 16 or older who has received the Privacy Policy and given express, specific, and informed authorization for LeanLens to process the photo and related body-analysis data for the requested feature, including disclosure to the identified service providers. Never upload a photo of anyone under 16 or anyone who has not given that authorization. You are responsible for verifying the depicted person’s age and authorization, and your own authority to upload. This responsibility does not limit the depicted person’s rights or LeanLens’s own obligations and liability under applicable law.

#The service and AI-generated estimates

LeanLens analyzes photos and optional profile information to generate body-composition and fitness estimates. Depending on the available feature and plan, outputs may include body-fat ranges, confidence, muscle and symmetry observations, physique context, progress trends, comparisons, peer benchmarks, and training or strategy guidance.

Future Physique is an optional Pro feature that uses a saved front photo to create private AI-generated illustrations for 4, 8, and 12 weeks. These images are illustrative, not forecasts, measurements, promises, or evidence of an achievable result. They may fail to preserve your appearance, likeness, pose, or background and may depict unrealistic or incorrect changes. Actual results vary.

LeanLens uses third-party AI providers described in the Privacy Policy and on the Subprocessors page. The service may decline or fail to analyze content that is unsafe, unsupported, or of insufficient quality.

Results are estimates, not measurements. They may be incomplete, inconsistent, or wrong and can vary because of lighting, pose, framing, clothing, image quality, profile inputs, model behavior, or ordinary changes between photos. Confidence and ranges do not make a result medically accurate.

LeanLens is not a medical device and does not provide medical advice, diagnosis, treatment, or an emergency service. Do not use a result to make a medical, medication, eating-disorder, or other high-stakes health decision. Seek a qualified professional for those decisions and emergency services for urgent help.

#Accounts and guest use

  • Guest use — a guest can request an analysis. Successful or degraded results may be saved against an anonymous identifier even without an account.
  • Your account — provide accurate information, keep access to your sign-in email secure, and tell support promptly if you suspect unauthorized access. You are responsible for activity reasonably attributable to your account.
  • Account linking — eligible guest activity may be linked to an account when you sign in, as described in the Privacy Policy and subject to its retention and deletion controls.
  • Deletion — you can start account deletion in Profile > Privacy & data or contact support if you cannot sign in. Account deletion and subscription cancellation are separate actions.

#Free and Pro access

Plan capabilities are shown in the product and may be protected by a configurable product-limit system. The current implemented defaults are:

  • Guest: A guest receives one successful initial analysis by default when product limits are enabled.
  • Signed-in Free: A signed-in Free user receives another successful analysis after a rolling 7-day window by default when product limits are enabled. Free users can retain and revisit history and receive limited trend and comparison features, but some result detail, rankings, comparisons, trends, peer context, and strategy content remain locked.
  • Allowance behavior: A failed analysis does not consume that Free allowance. Deleting a result does not restore it.
  • Pro: Pro removes the Free-plan waiting period, subject to reasonable abuse prevention, technical availability, and the current store-authoritative entitlement. Pro provides the deeper result, comparison, trend, benchmark, and strategy features identified as Pro in the product; availability can still depend on having enough valid data for a particular feature.

The offer and limits shown immediately before use or purchase control where they differ from these defaults. A plan label such as “unlimited” means no Free-plan waiting period; it does not remove reasonable abuse controls or guarantee uninterrupted service.

#Subscription, renewal and cancellation terms

The implemented mobile paywall supports monthly and annual subscriptions. No current free trial is implemented, and direct web purchasing is not implemented.

  • Offer and price — the launched storefront’s purchase screen controls the localized price, currency, billing period, taxes, and any offer-specific terms shown before confirmation. LeanLens does not charge a payment card directly on the web.
  • Trials and introductory offers — no current free trial is implemented. If a future storefront offer includes a trial or introductory period, its duration, eligibility, conversion price, and renewal terms must be shown before purchase and will control that offer.
  • Automatic renewal — a recurring Pro subscription renews at the interval and price shown by the storefront unless you cancel in the storefront before its stated renewal deadline. The storefront charges the payment method associated with your store account.
  • Cancellation — use Profile or the paywall to open the applicable storefront’s subscription settings, then cancel there. Cancellation normally stops future renewal rather than ending the paid entitlement immediately. Deleting LeanLens or deleting your account does not cancel the storefront subscription.
  • Expiry and billing issues — access can continue until the storefront-authoritative entitlement expires, including any grace or billing-retry state recognized by the storefront. After a Pro entitlement expires, Pro-only content and controls lock again. Existing saved history remains available under the access rules then shown in the product.
  • Restore — Profile and paywall flows include Restore Purchases. Use the same storefront account used for the purchase. A restore succeeds only when the storefront and subscription service confirm an active entitlement for the current LeanLens actor.
  • Refunds and billing disputes — the correct request path and decision-maker depend on the launched storefront, purchase terms, jurisdiction, and mandatory consumer rights. Storefront purchases must be managed through the applicable Apple App Store or Google Play process shown with the purchase, without limiting statutory withdrawal, conformity, refund, or chargeback rights that cannot lawfully be excluded.
  • Statutory withdrawal — if you are an EU or Portuguese consumer who buys at a distance, you may have 14 days from the contract date to withdraw without giving a reason. Store cancellation, a discretionary refund, and statutory withdrawal are different rights. If you expressly ask for service to begin during that period and later withdraw, the contracting professional may be entitled only to a proportionate amount for service properly supplied before withdrawal. You lose the right for a fully performed service only where all conditions required by law are met, including prior express consent and acknowledgment. Starting a subscription or accessing part of the service does not by itself waive the right. Send a clear withdrawal request to the Terms contact below. If a storefront supplied the purchase, its lawful withdrawal or refund route may also be used.
  • Price or plan changes — LeanLens may change future prices or feature availability for objectively valid reasons such as legal, security, technical, provider, abuse-prevention, or genuine product evolution needs. Changes must not impose an extra charge during the current paid period. Any renewal-price change, notice, consent requirement, or cancellation right will follow applicable law and the storefront contract. If a change to a continuously supplied digital service materially harms access or use, LeanLens will give reasonable advance notice on a durable medium and preserve any statutory right to terminate without charge, including the applicable 30-day right, unless an unchanged conforming version remains available without extra cost.

Apple and Google act under their own terms and privacy policies when they operate a storefront. Only a storefront offer actually displayed and available to you can be purchased.

#Your content and permission to operate LeanLens

You retain the rights you have in photos, profile inputs, feedback, and other content you submit. You confirm that you have the rights and permissions needed to submit it, that every identifiable depicted person is aged 16 or older and has given the authorization described above, and that the submission does not violate another person’s privacy, image, publicity, intellectual-property, or other rights.

You grant the service provider a limited, worldwide, non-exclusive licence to host, copy, transmit, transform, analyze, display, and otherwise process your content only as reasonably needed to provide, secure, support, and maintain the features you choose. This includes retaining analysis source media and processing records under current product behavior, saving requested progress, normalizing a saved front photo and generating private Future Physique illustrations when you request that Pro feature, and copying selected content into a share you create. The licence ends when the content is deleted except where continued retention is permitted or required by law, backups, unresolved disputes, safety, or the documented service lifecycle.

If you create an unlisted or public share, anyone with access may view and further copy it. You are responsible for the audience and for revoking the share when it should no longer be available.

If you intentionally or negligently breach the age, permission, authority, privacy, image, or intellectual-property promises in this section, you are responsible under applicable law for loss legally attributable to that breach. This is not a blanket indemnity and does not make you responsible for loss caused by LeanLens or remove LeanLens's own legal duties.

#Acceptable use

You must not:

  • upload content without the required rights or permission, upload a photo of anyone under 16, impersonate another person, or use outputs to harass, shame, discriminate against, or exploit anyone;
  • use LeanLens for medical diagnosis, emergencies, employment, insurance, credit, law enforcement, or another high-impact decision about a person;
  • bypass plan, access, safety, rate, or security controls, or obtain another person’s data or account without authorization;
  • scrape, crawl, reverse engineer, extract models or prompts, copy the service at scale, or use automated means except where law expressly permits the activity despite this restriction;
  • introduce malware, overload, disrupt, probe, or interfere with the service or its providers; or
  • use LeanLens in violation of applicable law.

#LeanLens intellectual property

LeanLens and its licensors own the service, software, design, brand, and content supplied by LeanLens, excluding your content. Subject to these Terms, you receive a personal, limited, revocable, non-transferable right to use the service for its intended consumer purpose. No other licence is granted.

#Availability, changes, suspension and termination

LeanLens may experience maintenance, provider failures, capacity limits, security incidents, or other interruptions. Features and supported platforms may change or be retired. LeanLens does not guarantee that every analysis will complete or that every feature will always be available.

LeanLens may restrict, suspend, or terminate access where reasonably necessary to enforce these Terms, protect users or the service, comply with law, address non-payment, or retire the service. A restriction must be proportionate to the reason. Unless urgent action is required for safety, security, illegality, or legal compliance, LeanLens will give reasonable notice. Where applicable law requires it, LeanLens will explain a content, account, or service restriction and identify an available review or redress route. If LeanLens ends or materially reduces a paid service, mandatory conformity, termination, and refund rights remain available. You may stop using LeanLens and request account deletion, but must cancel a mobile subscription separately.

To the extent permitted by law, LeanLens is provided on an “as available” basis and results are not warranted to be accurate, complete, uninterrupted, or suitable for a particular health or fitness outcome. Nothing in these Terms excludes warranties, remedies, or liabilities that applicable consumer law does not allow the parties to exclude.

Mandatory digital-service rights: Portuguese and EU consumer law may require LeanLens to supply a conforming digital service and security updates. If the service is not supplied or is not in conformity, remedies can include bringing it into conformity, a proportionate price reduction, termination, a refund, and recovery of eligible user-provided content. Some rights can also apply where a consumer supplies personal data rather than money. No disclaimer in these Terms removes those rights.

Liability: Nothing in these Terms excludes or limits liability for death; harm to physical or moral integrity or health; fraud; wilful misconduct or gross negligence; non-contractual property damage where exclusion is prohibited; defective performance or statutory digital-service remedies; breach of data-protection law; or any other liability or consumer remedy that cannot lawfully be excluded or limited. Subject to those rules, each party is responsible for loss legally attributable to its own breach. LeanLens is not responsible to the extent loss is caused by your breach, prohibited or high-stakes use, failure to follow clear warnings, or unauthorized third-party content, and only where the law permits that allocation. Because LeanLens is licensed for personal consumer use, it is not responsible for business-only losses such as lost profit, revenue, contracts, or commercial opportunity, to the extent that exclusion is lawful.

Governing law, courts, and consumer dispute resolution: Portuguese law governs to the extent that a choice of law is permitted. Consumers keep the mandatory protections, courts, complaint routes, and alternative dispute-resolution options available under the law of their country of habitual residence. A choice of law cannot deprive an EU consumer of mandatory protections in the country where they habitually live. A consumer may use the courts available under applicable law, including eligible courts in their home country; no exclusive Portuguese forum is imposed. Contact support@leanlens.ai for the complaint or consumer-dispute route applicable to your request. The former EU Online Dispute Resolution platform was discontinued and is not a current complaint route.

#Changes to these Terms and contact

LeanLens may update these Terms as the service or law changes. The date at the top identifies the current version. Material changes apply prospectively and will receive reasonable advance notice on a durable medium where required. LeanLens will request affirmative acceptance where the nature of the change or applicable law requires it; continued use is not treated as acceptance where affirmative assent is required. Effective July 21, 2026 for acceptances recorded against the July 20, 2026 Terms version and July 21, 2026 Privacy version.
