How your notes get to your cloud
What it does
Lyunotes keeps your notebooks as files in a folder you choose, your vault. Put that vault in the cloud you already use, and your notes follow you to your other devices, and today no Lyunotes server sits in between.
Supported clouds. Currently Dropbox, OneDrive and iCloud.
On Windows. On first launch, Lyunotes asks you to point at a folder. Pick a folder inside the one your cloud app already syncs, and that folder becomes your vault. Your cloud app moves the files; Lyunotes itself makes no connection to your cloud. Syncing this way is free.
On iPhone. You connect your cloud account (Dropbox, OneDrive or iCloud) in the app. Cloud sync is unlocked with Glyph, a one-time purchase (not a subscription).
Both together. Your iPhone and your Windows PC can open the same vault. Let sync finish before you switch devices. Lyunotes has safeguards that reduce the risk to your notes, but because we don't control your cloud's servers, we can't prevent every case: two devices changing the same notebook at the same moment can still conflict.

What your cloud can and can't see
What it does
Encryption is optional and per notebook. For the notebooks you turn it on for, the cloud only ever holds encrypted files.
Encrypted notebooks. Notes are encrypted on your device before your cloud sees them. The names of your notebooks, the titles and text of your notes, tags, folios and the names and contents of attached files can't be read in your cloud. What stays visible, such as how many notes there are and when things changed, is listed openly in what you can still see.
Ordinary notebooks. A notebook without encryption is stored as plain text, so anyone who can open your cloud account can read it.
Check it yourself. You don't have to take our word for it. Check it yourself shows how to open the files in your cloud and see for yourself.
Compared with keeping notes on a provider's servers
What's different
Many note apps keep your notes on the provider's own servers, so the provider can in principle read them unless it adds its own end-to-end encryption. Today, no Lyunotes server holds a copy of your notes. They live on your device and in the cloud you chose, and in an encrypted notebook the key comes from your password, which we never see.
The trade is yours to weigh: if you lose both your password and your recovery key, nobody can open the notebook, including us. The full list of limits is on What Lyunotes doesn't do.
Lyunotes is free on Windows, including sync through your own cloud. On iPhone, cloud sync is part of Glyph, a one-time purchase. Questions? Common questions.
