Is Obsidian private?
Yes: Obsidian stores your notes as files on your own device, says your data is never sent to its servers, and collects no telemetry. If you pay for Obsidian Sync, it is end-to-end encrypted by default.
What Obsidian says
- Vaults are ordinary folders of Markdown files on your device.
- Obsidian states it collects no telemetry. Update checks can be turned off.
- Obsidian Sync offers two modes: end-to-end encryption, which is the default, and an optional “standard encryption” mode whose key Obsidian manages and could use to decrypt your data.
- No account is needed to use the app; an email is needed only for purchases such as Sync.
What it does not cover
- The files on your device are not encrypted by Obsidian. Anything that can read your files — another app, a backup service, someone with your unlocked laptop — can read your notes. Full-disk encryption from your operating system helps when the device is off or locked.
- Community plugins run with access to your vault. Each one you install is code you are trusting.
- If you sync the vault folder with a general cloud drive instead of Obsidian Sync, that provider’s encryption rules apply.
Where Prevon differs
Prevon encrypts each note on the device itself, so a copied vault is unreadable without your 12 words, and builds in on-device AI instead of relying on plugins. Obsidian’s plain files are more portable, and it works today. Prevon vs Obsidian.
Prevon is in a private beta and has not had an independent security audit. It is designed so that we cannot read your notes; until someone outside the company has checked that, “designed” is the accurate word.
