Sunstreak (“we,” “our,” or “us”) created this Health & Safety page to help users understand how to use the Sunstreak: Sunscreen Tracker mobile application (“App”) responsibly and to support healthy sun-protection practices.
This page complements our Terms of Use and Privacy Policy.
By using the App, you acknowledge that you have read and understood this Health & Safety guidance.
Sunstreak is a wellness and habit-tracking application designed to encourage regular sunscreen use and raise UV-awareness.
Sunstreak is not a medical device and does not diagnose, treat, cure, or prevent any disease or medical condition.
To protect your skin and reduce UV-related risks, we recommend that users follow recognized public-health guidance, including:
• Apply a broad-spectrum, water-resistant sunscreen of SPF 30 or higher to all exposed skin.
• Apply sunscreen 15–30 minutes before sun exposure and re-apply at least every 2 hours, or sooner after swimming, sweating, or towel-drying.
• Combine sunscreen with protective clothing, wide-brimmed hats, sunglasses, and shade whenever possible.
• Try to avoid direct sun exposure during peak UV hours (10 a.m.–4 p.m.).
• For infants under 6 months, consult a qualified health-care provider before using sunscreen; keep infants in the shade and appropriately clothed.
These tips are for general educational purposes only and do not replace professional medical guidance.
• The UV-index readings in Sunstreak come from trusted third-party data providers (such as Apple WeatherKit).
• Actual UV exposure may vary due to factors such as altitude, reflective surfaces (water, snow), local weather, and shade.
• Use the UV index as a helpful guide, not a guarantee of personal risk.
• UV readings and forecasts may be inaccurate, delayed, or unavailable. If the App cannot load current data, do not assume UV levels are low.
• Sunstreak does not provide medical or dermatological advice.
• If you notice new or changing moles, suspicious spots, severe rashes, blistering sunburns, or other concerning symptoms, consult a licensed dermatologist or qualified health-care provider promptly.
• In any medical emergency—such as severe allergic reactions, heatstroke, or extensive blistering sunburn—call 911 (or your local emergency number) immediately.
Certain groups may be at higher risk of sun damage and should consult their health-care provider for personalized guidance:
• People with a history of skin cancer or precancerous lesions
• Individuals with photosensitive conditions or taking photosensitizing medications
• Children and adolescents, whose skin may be more sensitive
• People with light or freckled skin types who burn easily
• Sunstreak’s streak scores, UV badges, and reminders are informational tools only.
• A high score, an active streak, or a completed reapply timer does not mean your skin is adequately protected. Scores measure the habits you log, not your actual sun exposure.
• The reapply timer runs for whatever length you set. It is a reminder to help you build a habit, not a measure of how long your sunscreen lasts. When you are outdoors, reapply at least every 2 hours, and right after swimming or sweating, even if your timer is still running.
• Reapply reminders and notifications may be delayed or may not arrive (for example, if notifications are turned off, the device is in a low-power or focus mode, or the App is closed). Keep track of when you need to reapply sunscreen yourself.
• Always follow the product instructions on sunscreen labels and your health-care provider’s recommendations.
• Do not rely on Sunstreak as a substitute for regular skin examinations or professional medical consultations.
You use the App at your own risk. Our Terms of Use contain the binding disclaimers and limitations of liability that apply to the App, including for sunburn, skin damage, or other injury.
Sunstreak is committed to protecting user privacy:
• We do not collect or store Protected Health Information (PHI).
• Your sunscreen logs, streaks, and scores are stored only on your device, not on our servers.
• The personal data we do process (such as your email address and the location used to fetch UV data) is described in our Privacy Policy.
• We employ reasonable security measures to protect stored data, but no system is completely secure.
We may update these Health & Safety guidelines as sun-protection recommendations or app features evolve.
When we do, we will update the “Effective Date” above and make the revised version available within the App and on our website.
