What Tan Buddy is

Tan Buddy is a general-information and planning tool for consumers. It uses published models of ultraviolet radiation and skin response to produce estimates of how much ultraviolet exposure your skin may be receiving, and to suggest session lengths, timings and reminders based on information you enter about yourself.

What Tan Buddy is not

Tan Buddy is not a medical device. It has not been evaluated, cleared, approved or registered by the U.S. Food and Drug Administration, the European Medicines Agency, any Notified Body under the EU Medical Device Regulation, the UK MHRA, or any other regulatory authority. It is not intended to diagnose, treat, cure, mitigate or prevent any disease or medical condition, including sunburn, skin cancer, melanoma, photodermatoses, vitamin D deficiency, or any other condition.

Tan Buddy is not medical, dermatological, pharmaceutical or professional advice, and it is not a substitute for any of them. It cannot see your skin, does not know your medical history, does not know what medication you take, and does not know your genetic risk factors.

Tan Buddy is not a measuring instrument. It contains no ultraviolet sensor and takes no measurement of any kind from your body or your surroundings. Every number it displays is a calculated estimate derived from a third-party weather forecast and from information you have entered yourself.

The numbers are estimates, and they can be wrong

You acknowledge and agree that:

  • UV forecasts are forecasts. They are supplied by a third party (Open-Meteo), are modelled rather than measured at your position, and may be inaccurate, delayed, incomplete or unavailable. Cloud, haze, pollution, ozone, altitude, terrain, shade, water, snow, sand, glass, wind and time of day all affect real exposure in ways no forecast fully captures.
  • The skin model is a population average. The Fitzpatrick scale, the minimal erythemal doses, the tan-adaptation factors, the sunscreen factors and the vitamin D estimates in the app are drawn from published literature about groups of people. Individual skin varies enormously. Yours may burn very much faster than the app predicts.
  • Your inputs drive everything. If you select the wrong skin type, overstate your existing tan, misreport the sunscreen you are wearing, or fail to tell the app you take photosensitising medication, every number it shows you will be wrong — and it will be wrong in the direction of telling you it is safe to stay out longer than it is.
  • Sunscreen behaviour is unpredictable. The app assumes realistic under-application of sunscreen, but real protection depends on how much you apply, how evenly, how long ago, whether you have swum or sweated, and the product itself.
  • The app cannot know what you actually did. It does not know whether you went into the shade, went indoors, put clothes on, or stayed out after the timer finished.

You must not treat any output of the app as a guarantee, a promise, or a safe limit. Time, dose and burn figures are estimates only. Always use your own judgement, follow the guidance of your doctor or dermatologist, and get out of the sun if your skin feels hot, tight, itchy or looks pink — whatever the app says.

Health and safety — please read

There is no safe level of ultraviolet exposure. All ultraviolet exposure, including exposure that does not cause visible burning, and including exposure that produces a tan, causes DNA damage and increases the lifetime risk of skin cancer, including melanoma, as well as premature skin ageing, eye damage and immune suppression. A tan is itself a sign of skin injury. The World Health Organization, the International Agency for Research on Cancer and dermatological bodies worldwide advise minimising ultraviolet exposure.

The app is designed to help you take less ultraviolet radiation than you otherwise would, not to help you take more. Using it to justify longer or more frequent sun exposure than you would otherwise choose is a misuse of it and is done entirely at your own risk.

Do not use the app, and consult a doctor before any deliberate sun exposure, if you:

  • have a personal or family history of skin cancer, melanoma, or atypical moles;
  • have any photosensitivity disorder, lupus, porphyria, xeroderma pigmentosum, vitiligo, albinism or any other condition affecting the skin’s response to light;
  • take any photosensitising medication, including certain antibiotics (such as tetracyclines and fluoroquinolones), retinoids, diuretics, NSAIDs, antidepressants, antipsychotics, antifungals, chemotherapy agents, immunosuppressants, or St John’s Wort;
  • are pregnant, immunosuppressed, or recovering from a skin procedure;
  • have had a severe sunburn, particularly in childhood;
  • are under 18.

Never use the app in connection with sunbeds, tanning beds, sunlamps or any artificial tanning device. It models natural sunlight only, its numbers are meaningless for artificial sources, and such devices are classified as Group 1 carcinogens by the IARC.

If you think you may have burned, or you notice a mole that is new, changing, asymmetric, irregularly bordered, multicoloured, larger than 6 mm, itching or bleeding, stop using the app for that purpose and see a doctor. The app’s mole guidance is educational information about a widely published checklist; it is not a screening tool and cannot diagnose anything. In an emergency, contact your local emergency services.

Your responsibilities

You agree that:

  • you are at least 18 years old, or are using the app with the consent and supervision of a parent or guardian who accepts these Terms on your behalf;
  • you will provide accurate information about your skin, your age, your medication and your sun protection, and will update it when it changes;
  • you remain solely responsible for your own decisions about sun exposure, your own safety, and your own health;
  • you will not rely on the app as your sole source of information about sun safety;
  • you will keep your device charged and your notifications enabled if you intend to rely on the app’s reminders, and you accept that reminders may not be delivered;
  • you will use the app only for its intended personal, non-commercial purpose, and in compliance with all applicable laws.

You must not: reverse engineer, decompile or disassemble the app except to the extent that applicable law expressly permits it; rent, lease, lend, sell, redistribute or sublicense it; remove any proprietary notice; use it in any commercial tanning, salon, spa, medical or clinical setting; or use it to develop a competing product.

Reminders and notifications may not arrive

The app’s timers, flip reminders, sunscreen reminders and end-of-session alerts depend on iOS delivering local notifications, on your device being switched on and charged, on notification permission being granted, and on your device’s Focus, Do Not Disturb, Silent, Low Power and Sleep settings.

We do not guarantee that any reminder will be delivered, or delivered on time. Do not use the app as the only thing standing between you and sunburn, and do not fall asleep in the sun relying on it to wake you.

Third-party services

The app obtains UV forecast data from Open-Meteo. We do not control that service, do not warrant its accuracy or availability, and are not responsible for it. Its use is subject to its own terms. If it is unavailable, the app falls back to a clear-sky estimate calculated on your device, which ignores cloud cover and will overstate ultraviolet levels on cloudy days.

No warranties

The app is provided “as is” and “as available”, with all faults and without warranty of any kind. To the maximum extent permitted by applicable law, we disclaim all warranties, conditions, representations and terms, whether express, implied or statutory, including any implied warranties of merchantability, satisfactory quality, fitness for a particular purpose, accuracy, quiet enjoyment, and non-infringement.

Without limiting the above, we do not warrant that: the app will meet your requirements; that it will be uninterrupted, timely, secure or error-free; that any estimate, calculation, time, dose, forecast or reminder it produces will be accurate, complete or reliable; that defects will be corrected; or that the app will be compatible with any particular device or future version of iOS.

No advice or information, whether oral or written, obtained from us or through the app, creates any warranty not expressly stated in these Terms. Some jurisdictions do not allow the exclusion of implied warranties, so some of the above may not apply to you.

Limitation of liability

To the maximum extent permitted by applicable law, in no event shall iOS Visual, its owners, employees, contractors, agents, suppliers or licensors be liable for any injury, harm, loss or damage of any kind arising out of or in any way connected with your use of, or inability to use, the app.

This exclusion applies to all forms of loss and damage, including without limitation: sunburn, erythema, blistering, heatstroke, dehydration, eye damage, premature skin ageing, photosensitive reactions, skin cancer, melanoma, or any other injury, illness, disfigurement or death; and any indirect, incidental, special, consequential, punitive or exemplary damages, loss of profits, loss of data, loss of goodwill, cost of substitute services, or business interruption.

It applies regardless of the theory of liability — contract, tort (including negligence), strict liability, statute or otherwise — and even if we have been advised of the possibility of such damage, and even if a limited remedy is found to have failed of its essential purpose.

In any event, our total aggregate liability to you for all claims arising out of or relating to the app shall not exceed the greater of (a) the total amount you actually paid us for the app in the twelve months preceding the event giving rise to the claim, or (b) fifty euros (€50).

Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under applicable law. Some jurisdictions do not allow certain limitations of liability, so parts of this section may not apply to you; in that case our liability is limited to the greatest extent permitted by law. If you are a consumer, these Terms do not affect your statutory rights, which remain unaffected.

Indemnity

To the extent permitted by law, you agree to indemnify, defend and hold harmless iOS Visual and its owners, employees, contractors and agents from and against any claim, demand, liability, loss, damage, cost or expense (including reasonable legal fees) arising out of or connected with: your use or misuse of the app; your breach of these Terms; your provision of inaccurate information to the app; or your violation of any law or the rights of any third party.

Subscriptions, payment and cancellation

Tan Buddy Pro is an auto-renewing subscriptionsold through Apple’s In-App Purchase system.

  • Plans and prices are shown in the app before purchase, in your local currency, and are the prices that apply. Prices may change; you will be told in advance and asked to consent where Apple requires it.
  • Free trial.New subscribers may be offered a free trial of the length stated in the app. If offered and accepted, it converts automatically to a paid subscription at the end of the trial period unless cancelled at least 24 hours before it ends. Any unused portion of a free trial is forfeited when you purchase a subscription, where Apple’s rules so provide.
  • Renewal. Your subscription renews automatically at the then-current price unless it is cancelled at least 24 hours before the end of the current period. Your Apple Account is charged for renewal within 24 hours before the end of the current period.
  • Cancelling. You can cancel at any time in iOS Settings → your name → Subscriptions, or from the “Manage subscription” button at the top of the app’s own Settings screen. Cancelling stops future renewals; access continues until the end of the period you have already paid for.
  • Refunds are handled by Apple, not by us. We cannot issue refunds, and partial refunds are not provided for unused periods except where required by law. Refund requests go to Apple at reportaproblem.apple.com.
  • Purchases are managed by your Apple Account and are subject to Apple’s Media Services Terms and Conditions.
  • If your subscription lapses, Pro features stop working. Your own data remains on your device and becomes available again if you resubscribe.

Licence

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use one copy of the app on Apple-branded devices that you own or control, as permitted by the Apple Media Services Terms and the App Store’s Usage Rules, for your personal, non-commercial use.

We reserve all rights not expressly granted. The app, its source code, design, artwork, the “Sol” character, its text and its underlying models are owned by iOS Visual and protected by copyright and other intellectual-property laws. This is a licence, not a sale.

Your content

Any information, photographs and notes you enter remain yours. They stay on your device — we do not receive them and claim no rights in them. You are solely responsible for backing them up. Deleting the app permanently deletes them, and we cannot recover them.

Changes and termination

We may change, suspend or discontinue the app or any of its features at any time, with or without notice, and may update these Terms. Material changes will be signalled by the “Last updated” date and, where appropriate, in the app’s release notes. Your continued use of the app after a change takes effect constitutes acceptance of the revised Terms. If you do not accept them, stop using the app and delete it.

This agreement is effective until terminated. It terminates automatically without notice if you fail to comply with any of its provisions. We may also suspend or terminate your licence at any time if we reasonably believe you are misusing the app. On termination you must stop using the app and delete it. The sections on estimates, health and safety, no warranties, limitation of liability, indemnity, your content, governing law and these general provisions survive termination.

Apple

You acknowledge and agree that:

  • These Terms are between you and iOS Visual only, not with Apple. Apple is not responsible for the app or its content.
  • Apple has no obligation whatsoever to furnish any maintenance or support services in respect of the app.
  • If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app to you (if any). To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the app, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty are our sole responsibility.
  • Apple is not responsible for addressing any claims by you or any third party relating to the app or your possession or use of it, including product liability claims, any claim that the app fails to conform to any legal or regulatory requirement, and claims arising under consumer protection, privacy or similar legislation.
  • In the event of any third-party claim that the app or your possession and use of it infringes that third party’s intellectual property rights, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim.
  • You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
  • Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

Governing law and general

These Terms are governed by the laws of Italy, without regard to conflict of law provisions, and the courts of Turin, Italy shall have exclusive jurisdiction. If you are a consumer, this does not deprive you of the protection of the mandatory consumer-protection rules of the country in which you habitually reside, and you may also bring proceedings in the courts of that country. EU consumers may use the European Commission’s Online Dispute Resolution platform.

If any provision of these Terms is held unenforceable, it shall be modified to the minimum extent necessary to make it enforceable, or severed, and the remaining provisions remain in full force. Our failure to enforce any provision is not a waiver of it. These Terms and the Privacy Policy are the entire agreement between you and us concerning the app, and supersede all prior understandings. You may not assign these Terms; we may assign them in connection with a merger, acquisition or sale of assets. We are not liable for any failure or delay caused by events beyond our reasonable control. Headings are for convenience only and do not affect interpretation.
