ShelterSync
Read full descriptionHide full description
ShelterSync is the mobile app for animal-shelter volunteers, staff, and foster caregivers. You need an account from a shelter that uses ShelterSync. Accounts are created by your shelter's coordinator — you can't sign up in the app. If your shelter hasn't set you up yet, ask them before installing. WHAT YOU CAN DO Find the animal in front of you Browse the animals available to you, or point your camera at the QR code on a kennel card to open that animal's record straight away. Log activities as you do them Start a walk, play session, or socialization, and end it when you're done. A short follow-up question or two captures what you noticed while it's fresh. See what an animal needs Each animal shows its activity goals and how it's tracking, so you can spend your time where it counts rather than guessing. Foster from home If you foster, the animals placed with you appear in the app and your time with them counts the same as time at the shelter. Log a session live, or record one afterwards when real life got in the way. If your shelter uses observation forms, you can share what you see at home — how they sleep, eat, and settle — directly into the animal's record. Keep track of what's coming See your shelter's upcoming events and any activity you left running, in one place. ABOUT YOUR PRIVACY The camera is used for one thing: reading the QR or barcode on a kennel card. Scanning happens on your device, and no image or video is ever stored or uploaded. Camera access is the only permission the app asks for. There's no advertising, no third-party tracking, and no user-to-user messaging. Your information is visible to the shelter you volunteer with, and not to other volunteers. Full privacy policy: https://docs.mysheltersync.com/legal/privacy ShelterSync is made by Zoolytix for shelters and rescues. Minimum age 13; some shelters set a higher age of their own.
