Privacy

On Your Device

Folio keeps its own copy of your notes, notebooks, and tags in the app's private storage area on your iPhone or iPad — nowhere else on the device, and nowhere the app can be reached from except by you opening it.

A handful of small preferences — things like appearance and sync mode — are stored the same way, using Apple's standard UserDefaults mechanism. These are settings, not content: none of them describe you, and none of them leave the device except as part of an iCloud device backup you control.

Your Private iCloud

If you leave sync turned on, each of your notes, notebooks, and tags is also mirrored to your own private CloudKit database — container iCloud.com.burningsquirrelproductions.Folio — the same private-by-default storage Apple gives every app, tied to your Apple ID. It is not a shared or public database: only devices signed into your own iCloud account can read it, the same way only your devices can read your iCloud Photos or iCloud Drive files.

We — the developer — have no access to this database. There is no server of ours in the loop, no copy on our infrastructure, and no way for us to see a single one of your notes, notebooks, and tags. Apple's standard iCloud security and encryption protects it the same way it protects everything else in your iCloud account.

What We Never Do

Your Control

Settings → iCloud lets you switch to local only at any time. Doing so deletes Folio's iCloud copy of your notes, notebooks, and tags (after you confirm) and stops syncing from then on — your notes, notebooks, and tags stay only on this device.

Deleting the app removes its on-device copy along with it. There's no "delete my account" step, because there was never an account to begin with.
