Terms of Use
Last updated: 28 June 2026
These Terms of Use (the “Terms”) are a binding agreement between you and TanCue (“TanCue”, “we”, “us”) governing your use of the TanCue iPhone app and related services (the “App”). By downloading, accessing, or using the App, you agree to these Terms. If you do not agree, please do not use the App.
1. Acceptance of these terms
By installing or using the App you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated here by reference. If you are using the App on behalf of someone else, you confirm you are authorized to accept these Terms for them.
2. About TanCue
TanCue is a UV-aware tanning planner and self-tracking tool. It provides live UV information, an hour-by-hour forecast, a burn-risk indicator, session planning and timers, and — with TanCue Pro — an on-device AI coach, guided routines, and tracking features. TanCue is a lifestyle and wellness tool. It is not a medical device or medical service (see Section 9).
3. Eligibility & age
You must be at least the age of digital consent in your country (for example, 13 in the United States and up to 16 in parts of the EEA) to use the App. The App is not directed to children, and we do not knowingly collect personal data from children. If you are a minor, you may use the App only with the involvement and consent of a parent or guardian.
4. Your licence to use the app
Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable licence to download and use the App on an Apple-branded device that you own or control, for your personal, non-commercial use. You may not copy, modify, distribute, sell, lease, reverse-engineer, or attempt to extract the source code of the App, except to the extent this restriction is prohibited by law.
5. Free features & TanCue Pro
Core sun-safety information — live UV, the hourly forecast, your burn-risk state, and the “cover up now” alert — is provided free of charge and is never placed behind a paywall. “TanCue Pro” is an optional paid subscription that unlocks additional coaching, optimization, and convenience features, such as the AI coach and plan generation, guided session routines, Live Activity and Home-Screen widgets, goal modes, the on-device skin-tone read, and unlimited history, streaks, and reminders. Features may be added, changed, or removed over time.
6. Subscriptions & billing
TanCue Pro is offered as an auto-renewing subscription (for example, weekly and yearly options). Subscriptions are sold and processed through your Apple App Store account, and subscription status is managed with the help of our service provider, RevenueCat.
- Payment. Payment is charged to your Apple ID account upon confirmation of purchase.
- Auto-renewal. Your subscription automatically renews for the same period unless you turn off auto-renew at least 24 hours before the end of the current period.
- Renewal charge. Your account is charged for renewal within 24 hours prior to the end of the current period, at the price of the selected plan.
- Manage or cancel. You can manage or cancel your subscription anytime in iPhone Settings → [your name] → Subscriptions. Cancellation takes effect at the end of the current billing period.
- Restore. You can restore a previous purchase from the App’s paywall by tapping Restore.
- Refunds. Purchases are handled by Apple. Refund requests are subject to Apple’s policies and applicable law; we generally cannot issue refunds directly for App Store purchases.
- Price changes. If we change subscription prices, the new price will not apply to your current period and Apple will seek your consent where required before any increased renewal.
7. Free trials
We may offer a free trial for some subscription options. Unless you cancel at least 24 hours before the trial ends, the trial automatically converts to a paid subscription and your Apple ID is charged. If you start a paid subscription, any unused portion of a free trial is forfeited. The availability and length of any trial may vary and may be withdrawn at any time.
8. Acceptable use
You agree to use the App only for lawful purposes and not to: misuse or interfere with the App or its supporting infrastructure; attempt to gain unauthorized access to any system or data; use the App in any way that could harm you or others; or rely on the App as a substitute for professional medical, dermatological, or safety advice.
9. Sun-safety & medical disclaimer
TanCue is not a medical device and does not provide medical advice, diagnosis, or treatment. The App provides general, “lower-risk” sun guidance and self-tracking — it does not make tanning “safe.” UV readings, forecasts, recommended times, and SPF suggestions are estimates based on third-party weather data and your inputs, and may be inaccurate; conditions can change quickly.
You are responsible for your own sun-exposure decisions. To the fullest extent permitted by law, we are not liable for sunburn, skin damage, or other harm resulting from your use of, or reliance on, the App.
10. AI-generated guidance
Some features use on-device artificial intelligence (including Apple’s built-in models) to generate plans, explanations, and recommendations. AI output can be incomplete or wrong and is provided for general informational purposes only. Use your own judgment and do not treat AI-generated content as professional advice.
11. Third-party services
The App relies on third-party services to function, including Apple (App Store, WeatherKit, on-device frameworks), RevenueCat (subscription management), and PostHog (privacy-friendly analytics, hosted in the EU). Your use of those services may also be governed by their own terms and privacy policies. We are not responsible for third-party services we do not control.
12. Intellectual property
The App, including its software, design, text, graphics, the “Cue” mascot, logos, and other content, is owned by TanCue or its licensors and is protected by intellectual-property laws. Except for the licence granted in Section 4, no rights are transferred to you. “TanCue” and associated marks may not be used without our prior written permission.
13. Disclaimer of warranties
The App is provided “as is” and “as available,” without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that any data (including UV or weather information) will be accurate or reliable. Some jurisdictions do not allow certain warranty exclusions, so some of the above may not apply to you.
14. Limitation of liability
To the fullest extent permitted by law, TanCue and its suppliers will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising out of or related to your use of (or inability to use) the App. To the extent we are found liable, our total liability for all claims relating to the App will not exceed the greater of the amount you paid us for the App in the 12 months before the claim, or USD 50. Nothing in these Terms limits liability that cannot be limited under applicable law.
15. Indemnification
You agree to indemnify and hold harmless TanCue and its officers, employees, and agents from any claims, damages, or expenses (including reasonable legal fees) arising from your misuse of the App or your violation of these Terms or applicable law.
16. Changes
We may update the App and these Terms from time to time. When we make material changes, we will update the “Last updated” date above and, where appropriate, provide additional notice. Your continued use of the App after changes take effect means you accept the revised Terms.
17. Termination
You may stop using the App at any time by deleting it. We may suspend or terminate your access if you breach these Terms or use the App in a way that could cause harm or legal liability. Sections that by their nature should survive termination (including disclaimers, limitation of liability, and intellectual-property terms) will survive.
18. Governing law
These Terms are governed by the laws applicable at TanCue’s principal place of business, without regard to its conflict-of-laws rules, except where mandatory consumer-protection laws of your country of residence apply. Nothing in these Terms affects your statutory rights as a consumer.
19. Apple App Store terms
The following applies because you obtained the App through the Apple App Store:
- These Terms are between you and TanCue only, not with Apple. Apple is not responsible for the App or its content.
- Apple has no obligation to provide any maintenance or support for the App.
- To the extent permitted by law, Apple has no warranty obligation with respect to the App, and any claims for failure to conform to a warranty are TanCue’s responsibility.
- Apple is not responsible for addressing any claims relating to the App, including product-liability, regulatory, or consumer-protection claims.
- Apple is not responsible for investigating or resolving any third-party intellectual-property claim relating to the App.
- You represent that you are not located in a country subject to a U.S. Government embargo or designated as “terrorist-supporting,” and that you are not on any U.S. Government restricted-parties list.
- Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
