About COVID Alert CT

COVID Alert CT is the official COVID-19 exposure notification app in the State of Connecticut. It is supported by the Connecticut Department of Public Health (CT-DPH). COVID Alert CT helps to contain the spread of COVID-19 by complementing the ongoing contact tracing programs carried out by the State and local health departments.
Using COVID Alert CT is voluntary and free of charge. The more people who install and use the app, the more effectively the app can help us to contain and slow the spread of the virus.
Once you install and activate COVID Alert CT and turn on Bluetooth, the app works in the background and exchanges anonymous keys with other devices. Keys are long random strings of characters that are not tied to any personal information. Phones will record the keys generated by other phones nearby with the app installed. The app will record the:
- signal strength, and use that to estimate the distance between devices,
- duration of the contact and
- date of the exposure.
To protect the users’ privacy, these keys are only kept on the user’s own device. After 14 days the keys are deleted.
If a COVID Alert CT user tests positive for COVID-19, they will be able to obtain a verification code from a contact tracer at the State DPH or local health department. The code allows the user to activate the notification function in the app. You must use the verification code in order to report a positive result via the app. This prevents people from falsely reporting positive results, and false exposure notifications. CT-DPH wants all app users to feel confident that when a possible COVID-19 exposure is received via the app, that it is a real event.
A positive report warns other app users that were near the infected person in the period close to the time when that person first experienced symptoms of the disease under certain circumstances. If the estimated distance was within six feet, the duration of exposure was at least 15 minutes cumulatively, then the other user receives a notification of a possible exposure. Anyone who receives a notification should follow the guidance in the app for next steps.
CT-DPH takes your privacy and confidentiality very seriously. This is why we chose to use the Apple and Google Exposure Notification API. No personal data or location tracking occurs within this app. There is no need for CT-DPH to know where or who you are, for COVID Alert CT to work.
The Connecticut COVID Notice Privacy Policy is available at https://portal.ct.gov/coronavirus/COVIDAlertCT/PrivacyPolicy. The use of the app is limited to Connecticut and is subject to Connecticut law.
Thank you for downloading COVID Alert CT. Together, we can protect our family, friends, neighbors, and colleagues, and keep Connecticut moving forward.
The app was developed using the Google / Apple Exposure Notification API through a collaboration between Google, Apple, the Connecticut Department of Administrative Services (DAS) and CT-DPH.

Dec 19, 2020 I'm not sure how to rate this app (see the XKCD comic on tornado warnings). I'm mostly reviewing to point out a SERIOUS flaw in the design of this app. I live on the border w/ NY. NY has it's own identical app. I can not run both apps at the same time. So I have to pick between CT or NY. What is the reason for this and why is this administered by the states at all? Why isn't there a national app?more -
Nov 27, 2020 Bluetooth and location are always on. Significant battery drain. When a covid notification pops up, it does not take you to view that information. Rather you have to download the active app or you just get a spinning wheel. -
Dec 1, 2020 Impressive. I am impressed at the effort expended by the State of CT to ensure the safety of its residents, creating an app to track and notify exposure to the threat of a virus that kills approximately 1% of the population (not counting the elderly and those co-morbid), and at the same time continue with the virus-turned-political-weapon that is the COVID19/WUHAN virus. I recall an era when individuals whom presented a threat to the health of others were the ones quarantined. Ugh.more -
Nov 13, 2020 Happy with this app so far. It was easy to set up. I like that it focuses on privacy (no permissions required, data anonimized, etc) while helping me do my part to keep us all safe. -
Dec 4, 2020 I'm glad the State is doing this, but being near someone's app isn't enough. Not everyone has the app. Why aren't we informed of cases in our town? No personal information needed. I know someone who is positive, and that would be good to know how many, if any cases are in my town w/o having to go to DPH.more

Dec 28, 2020 Why ONLY allow the fingerprint scan option and not offer the password/pin option? (Meanning I cannot access the scanned list). Is it that challenging for the devs to realize we all don't utilize/have access to the SAME FEATURES. This app is the equivalent of a paperweight, in my phone.more -
Jan 14, 2021 Why can't I use this with another COVID exposure notification app? I live near both CT and NY. This should definitely be something to consider. -
Nov 30, 2020 Contact tracing is a joke..... My kids have had covid for over a week and a half now, no one has called... I've had it for a week now and no one has called. And u can't report it to the app without be contacted, so someone infected is going around infecting other and not knowing it. Great job CT!more -
Dec 3, 2020 App does not work! I go to turn on exposure notifications and I get the error "something went wrong" and no way to contact Devs of how to fix this. I wanted to specifically use this while out tomorrow. -
Jan 7, 2021 This App does nothing, I have been in contact with several people who had tested positive for COVID and this app did not alert me to anything.

Nov 29, 2020 Nice app, like others have said i appreciate that it doesnt require permissions and the privacy model is transparent. Only thing that could make it better is if it was open source. -
Nov 13, 2020 The app requires ZERO permissions on your phone. the app doesn't know who you are, and doesn't know where you are. They did a great job at anonymizing your data. again, GPS IS NOT REQUIRED OR ASKED FOR. it's either we install this app or shutdown the country.more -
Nov 15, 2020 Installed without any issues. I was worried that it might drain the battery but so far, it uses so little it registers as 0% per hour.

Nov 28, 2020 I hope this updates with past exposures/past positive testers too since I just installed it & it's only providing new reports, of which it's currently empty. Also hope the Samsung Secure Folder installation glitch will be fixed soon.more -
Nov 15, 2020 Great app. I was reading Wormwood a book about apocalypse in Connecticut and the app reminded me of the one the main character has in that book. Its also nice to know when its better to just stay home.

Dec 28, 2020 I never recieved an alert even though I have it set up to alert me. It did notify inside the app but I would have never known if I hadn't looked. -
Nov 13, 2020 You have to keep your location and Bluetooth on for it to work. That eats up battery. Otherwise it's functional. 🤷🏽♀️

What’s Groovy
The way I understand it, you only get notifications if an exposed person has downloaded this app and gives permission to share data. Those who have been exposed but saw no alert, the person may not have had this app. The app is only as accurate as the number of people using it; it's open-source data collection and completely voluntary. More residents should download this app.

What’s Subpar
I work in a residential facility where both staff and residents have cell phones. Not once, with any positive case, has this app notified me of an exposure. Very disappointing.

I have never received a warning no I'm not sure if the app works or not. I have been diagnosed with Covid-19. I went to put it on the app. And it asks for a code. What code. I got a test result not a code for a gift card. And no explanation on the app as to where I find or get a code. Maybe this is why I haven't received any warnings. Should have known something from the CT government would not work well
