Drive files, photos, Docs, Notes and Pass entries are encrypted on your device before they are uploaded. We store only encrypted data that we cannot open without your keys.
Mail and calendar need some information to be delivered and synced, such as who a message is sent to. Our privacy policy explains exactly what.
When you sync calendar and contacts to another app, that app sends your password to our server so it can unlock the data for the device. In the InfoPeak app your password never leaves your device.
The flip side of zero-knowledge is that we cannot reset your encryption. Keep your recovery key safe.
