How much will it cost?

Airday will be free to use offline. Sync between devices will initially be offered for USD$36 per year.

Can I use it offline?

Absolutely yes, Airday is built on local-first principles. Some online-only features will be introduced later e.g. file upload.

Are there iOS and Android apps?

The iOS app is in development and an Android version will follow. For the time being, the web version can be accessed on mobile.

Can I sync with Apple and Google Calendar?

CalDAV integration is in the works for Apple Calendar, but will not be available at launch. Google integration is not planned yet.

Can I self-host it?

Yes, the sqlite version of Airday is designed to be easily self-hosted. It will be made available at the same time as the hosted version.

Is Airday open source?

Airday's community version will be open source under the AGPL-3.0 license. Parts of the hosted version will be proprietary. Data can be transferred between each.

Is Airday end-to-end encrypted (E2EE)?

Yes, user data (except for authentication and config) is E2EE. Where server access is needed, e.g. in the case of a server-side CALDav adapter, it will be explicitly granted by the user and a separate server managed key will be used to manage that set of data.
