Need help, found a bug, or have a feature request? Email apps@katr.com. We read every message.
Where is my data stored?
On your device only. The app has no account and does not send your data anywhere. See the
Privacy Policy.
Does the app tell me what herbs are used for?
No. It is a journal for your own notes. The only built-in information is a list of plant names and families to save you
typing. Nothing in the app is medical advice. See the Terms.
How do I move to a new phone, or keep a copy?
Settings, then Backup and restore, then Create backup. Save the file somewhere safe (for example Google Drive), and on the
new phone choose Restore or import. See the How-To Guide.
I forgot my backup passphrase.
We cannot recover it. The file is encrypted on your device with a key made from your passphrase, and we never have either.
Keep your passphrase somewhere safe, and consider also keeping an unprotected backup in a private place.
I forgot my PIN.
The PIN is stored only on your device and we cannot reset it. That is why we recommend keeping a backup of your data.
How do I make my own sections or tabs?
Settings, then Sections and tabs. See the How-To Guide.
I did not get a batch reminder.
Check that Batch reminders is on in the app's Settings, that notifications are allowed for the app in Android's settings,
and that battery saver is not blocking background alarms for it.
Can I share my herbs with a friend?
Yes. Open an herb, recipe or remedy and tap Share, or share your whole collection from Backup. Photos travel with it.
Email apps@katr.com with as much detail as you can: your device model, Android version, and the steps to reproduce a bug are especially helpful.
