Something wrong, or a question? Write to calluna@boite-a-reves.fr. Calluna is made by one person, so a reply can take a few days — but it always comes.
Most questions have a quick answer below. The ones about getting your journal back are first, because they matter most.
Your journal, and how not to lose it
I'm changing phone. How do I bring my journal with me?
Your journal lives on your phone and nowhere else, so it needs a copy before you switch. Two ways, and you can use both:
- Back up to your own Google Drive — in Settings → Backup. On the new phone, install Calluna, connect the same Google account, and choose "Restore".
- Export to a file — also in Settings → Backup. You get a
single
.zipcontaining your words and your photos. Put it somewhere safe (Files, iCloud Drive, a computer, an email to yourself), then import it on the new phone.
On iPhone, your journal is also included in your device's iCloud backup, so setting up a new iPhone from that backup brings Calluna's data with it. That happens on its own — but it only helps if you actually restore from a backup, which is why the two options above are still worth doing.
I uninstalled the app. Is everything gone?
If you had no backup, yes — and we can't recover it, because we never had it. That's the other side of a journal that stays on your phone: nobody can read it, and nobody can bring it back for you.
My photos aren't in the export
They are, if you exported the .zip. The older .json export only
contained text. If a photo is missing from the zip, it usually means the file was removed
from the phone's storage outside the app — reinstalling won't bring it back.
I can't find the Google Drive option
It only appears where it can actually work. If the option isn't there, this build of the app isn't set up for Drive on your platform — use "Export to a file" instead, which never depends on anything external.
Reminders
My evening reminder doesn't arrive
Three things to check, in this order:
- notifications are allowed for Calluna in your phone's system settings;
- the reminder is switched on in Settings → Reminder, at a time that hasn't already passed today;
- battery saving isn't putting the app to sleep — some phones are aggressive about this, and Calluna can't override it.
Reminders never contain anything you wrote. They're generic, and composed on your phone.
How do I stop them?
One switch in Settings → Reminder. Turning it off also deletes the corresponding record on our side, immediately.
Privacy and the app's behaviour
Do I need an account?
No. No email address, no password, nothing to create. You open the app and you write.
How do I lock the app?
Settings → Privacy, if your phone has a fingerprint sensor, face recognition, or a passcode set. It's a door on the app, not encryption of the files underneath — enough against someone picking up your phone, not against a determined attacker with the device in hand.
How do I delete everything?
"Erase everything", in Settings. It clears what's on the phone. If you had backups on your Drive, delete the "Calluna" folder there as well — those files are yours, in your account, and only you can remove them.
Can I turn off the anonymous statistics?
Yes, in one tap: Settings → Privacy → Anonymous statistics. What is and isn't measured is spelled out in the privacy policy.
Reporting a problem
If something is broken, the following makes it far more likely to get fixed quickly:
- what you did, and what happened instead;
- your phone model and system version;
- the app version — it's at the bottom of Settings;
- a screenshot, if the problem can be seen.
Please don't send screenshots of your journal entries unless the bug is in them. They're yours, and there's rarely any need for us to see them.
Things Calluna deliberately doesn't do
Some questions come back often enough to answer here, because the answer is "on purpose, and it won't change":
- There's no field for what went wrong in your day. Only the good things.
- There's no mood chart, and no streak you can break. A day you skip is just a day without growth.
- Nothing dies in your garden, and nothing goes backwards.
