doMahan 0.6.1: Safer Backups and Shared Phones

This one is a quiet update. You won't see new buttons on the main screens. What changed is underneath, in how backup and privacy work, and it's the kind of thing that only matters on the day it matters a lot.

Shared phones

Plenty of phones get shared. A family tablet, a phone handed down to a younger sibling, a work phone that changes hands.

Until now, if one person had notes on the phone and then a different Google account signed in to doMahan, the notes already on the phone would be backed up into the new account. That's fine if both accounts belong to the same person. It isn't fine if they don't.

In 0.6.1 the phone remembers whose notes it holds. If a different account signs in while those notes are still there, backup pauses and doMahan asks what should happen:

They're mine, add them keeps the notes and backs them up to the account that just signed in, for people with two Google accounts of their own
Remove them from this phone clears the phone and brings in that account's own backup instead
Sign out leaves everything as it was

Nothing moves between accounts until someone picks one.

Signing out can clean up after you

Sign out used to leave all your notes on the phone. That's still the default, but there's now a second choice: Sign out and remove from this phone. doMahan backs up one last time first, and only removes anything if that backup worked. If you're offline, it tells you and keeps everything.

It's useful when you're selling a phone, handing it on, or you just signed in on someone else's for a minute.

Backup is more careful about old edits

doMahan works offline, so sometimes a phone holds edits that haven't been backed up yet. Before, when it came back online, it sent its own changes first. If you had edited the same card on another phone in the meantime, the older offline edit could win.

Now it brings in the newest changes first, keeps whichever version is newer, and only then sends its own. The newest edit wins, whichever phone it came from.

Smaller things

Deleted cards and spends now go to the cloud as empty markers, so the words or amounts don't stay in your backup after you delete them. The marker only exists so your other phones know to delete the card too.

If your phone is set to hide private content on the lock screen, reminders now show "doMahan reminder - Unlock to see it" there instead of the card's text. If your phone shows everything on the lock screen, nothing changes.

And if you export your data to a spreadsheet, a card that starts with a symbol like = or + can no longer be read as a formula when you open the file.

Getting it

The update is rolling out on Google Play now. If your phone updates apps by itself, you don't need to do anything. Your notes and your backup stay exactly as they are.

The privacy policy has been updated to describe all of this. If something doesn't work the way you expect, Profile and settings > Send feedback comes straight to me.

One more thing while you're here: there are now free printable planners on the site, for anyone who likes paper. A daily planner, weekly planner, monthly calendar, habit tracker and to-do list, in A4 and US Letter.

Quick answers

What is new in doMahan 0.6.1?

Safer backup and more privacy. The app asks before backing up notes when a different Google account signs in, sign out can remove your notes from the phone, an older edit can no longer replace a newer one during backup, deleted notes are emptied in the cloud, and reminders stay private on a locked phone that hides notification content.

Do I need to do anything after updating?

No. Update from Google Play and keep using the app as before. Your notes and your backup stay as they are.

What happens if someone else signs in to doMahan on my phone?

If your notes are on the phone and a different Google account signs in, doMahan pauses backup and asks whether to add the notes to that account, remove them from the phone, or sign out. Nothing moves between accounts until someone chooses.
