For the photos you'd rather not see, but do want to keep. Diapers, skin, injuries, vomit. Kenoco keeps those photos out of your usual camera roll and tucks them into the app's own protected space. When you need them, look back through them or show your doctor. You take the photo because the pediatrician is going to ask. But then it sits in your camera roll next to the birthday pictures, and two years later it turns up in a memories slideshow. Kenoco quietly keeps those photos apart. ■ Never Touches Your Camera Roll Photos taken with Kenoco's built-in camera are saved to the app's own protected storage, not to your photo library. Already took the shot? Import it from your photo library and Kenoco keeps its own copy. ■ Masked by Default Everything in your log is blurred until you tap it. Open the app in a waiting room without thinking about what's on screen. ■ A Timeline You Can Actually Read Log by category: diaper, vomit, skin, injury, and other. Entries line up by date, so "how long has this been going on?" has an answer. ■ Show Your Doctor Mode At the appointment, switch to a view built for handing your phone over. It goes back to masked automatically after five minutes. ■ What You Can Record • Photos and notes • Symptom tags • Stool color and consistency • A separate log per child, with app lock ■ Privacy Kenoco has no account of its own. By default, your records stay on your device. Family sharing and AI observations are optional, and each one runs only when you turn it on yourself. ■ Kenoco Plus (Optional) • Unlimited photo entries (free plan: 10) • Unlimited children (free plan: 2) • Family sharing, encrypted and synced through iCloud The free plan keeps the basics forever: hide the photos, log them, lock the app. Kenoco is not a medical device. Your records and any auto-generated notes are for reference only and are not diagnostic information. If something concerns you, please contact a local medical or health service.
