Privacy by design
All data you provide stays on your phone. We don’t track what you do in the app
Ethical by design
We don’t exploit psychological vulnerabilities. No bottomless feeds, auto-play or anything to keep you from leaving.
100% Open source
Everyone can read and improve the code of the app, verify carbon models, suggest features, and fix any incorrect information on Github
We are transparent
You can check our figures at any time. Incomings, outgoings and everything in between. All public and forever will be.
We are here to disappear
We don't want our app to be used forever. We are here to give you information and tools so you can understand, learn and continue without our input.
With Family Sharing set up, up to six family members can use this app.
