End-to-end encrypted sync

Your journal, for your eyes only

Use whatever storage you like — your data is encrypted on your device before it's uploaded. The cloud only ever gets ciphertext.

Privacy is the default, not a toggle

Islet was built around two goals from day one: your data is never lost, and privacy comes first. That's why configuring sync and end-to-end encryption come before you start — not options bolted on later.

Set up first — loss ruled out by designData never lives on just one device. Sync is required, so a lost or wiped phone never means lost entries.

Encrypted locally, ciphertext in the cloudEncryption happens on your device. S3 / WebDAV only ever hold ciphertext — even your provider sees gibberish.

Your storage, never our serversSync runs straight between your device and your S3 or WebDAV. No middleman, so we can't touch your data.

No account, nothing collectedNo sign-up, no personal details. Islet is a pure tool — you're its only owner.
