Scary Privacy Policy

Scary Privacy Policy, looks like these guys take the whole lot.... This could be very dangerous....

The privacy policy does state the information they take, and it's surprising, I don't think they've missed anything out... It looks like they take all of your health data, then personal information, then, from reviews, FB details...

Should this app be allowed on App-store?

Dear C8ip,

We understand your concerns – we do analyze huge amounts of your data. The purpose of our app is to help you estimate your lifespan based on health information collected by your smartphone or fitness tracker. That’s why we need your health data – otherwise, we will not be able to assess your health. If you decide to use Facebook to log in, we will also use Facebook profile data to identify you.

It is important for us to be explicit and transparent in our data collection, storage, and usage Policy. That’s why we ask every user to read our Terms and Conditions before beginning to work with Gero Lifespan. In short, we de-identify all your health data and store it that way, and we never sell, rent, or lease your contact information.

We take the privacy of our users very seriously and doing our best to keep the data protected. We are experienced in work with sensitive information and trusted by UK Biobank to have assess to the health data of 500,000 users. Nevertheless, it’s up to you to decide whether to use our app or not.

We will be more than happy to answer any specific questions you might have. Just drop us a line at hello@getgero.com

With love from Gero,



Great app

We are so happy to hear that! Thank you for being with us :)


Won’t start without connecting to Facebook

It then requests access for data from various health tracking apps and for some reason Instagram. No matter how much data I have granted access to, the app still fails to produce any meaningful result for me. It estimates my lifespan at 0.0 At least I hope that was a failure in their algorithm rather than a honest prediction, that I am about to die any day now.

Hi, Shmoola! We are adding other authorization options. If Instagram aссess is enabled, the app will display recent photos to help you connect your lifestyle with sudden lifespan changes. Please message us at hello@getgero.com if you still get 0.0, we will fix the problem!
