Questions

Where is my data stored?

Only on your iPhone. The Kest app has no accounts and no servers of its own. Nothing you enter in the app is sent to us. If you back up your iPhone, it is included in your own backup.

Does Kest move money?

No. Kest never connects to your bank or makes payments. It keeps the record, and regular payments can be set to count as paid on the day they go out.

What if I lose or replace my phone?

Restoring your new iPhone from an iCloud or computer backup usually brings your Kest data with it. You can also use Export all data in Settings to keep your own copy.

Is it free?

Yes. Kest will be free to download and use.
