Privacy Policy for Folio

Last updated: August 10, 2026

What we collect

Your notes: nothing. Folio has no accounts and no advertising. We cannot see your notes, photos, or attachments — that content never leaves your device except through your own iCloud sync.

Separately, Folio sends anonymous usage analytics to a server we operate ourselves. This is a small, fixed set of events with no free-text fields — it never includes the content of your notes. Details are in the next section.

Usage analytics

Folio sends anonymous, on-by-default usage analytics to a server we operate. It is a short list of events, and nothing else:

• app_open — with a flag for whether it was a cold start
• first_launch
• purchase — product id, transaction id, and whether it was a purchase or a restore
• paywall_view — where the paywall was shown from
• feature_used — the name of a feature, from a fixed list we define
• error — an error domain and a numeric code
• opt_out — recorded when you turn analytics off

Alongside each event we record a random ID generated on your device when you first install the app — not an Apple device identifier, not shared with any other app, and not linked to your identity — plus app version, iOS version, device model (e.g. "iPhone16,2"), language, and your 2-letter country. There are no free-text fields. Analytics never sees the text of your notes, your photos or attachments, or anything else you've typed.

We do not store IP addresses, even in logs; an IP is hashed with a key that rotates daily, used only to rate-limit abuse, and then discarded. Raw events are deleted after 90 days. Analytics never goes to an ad network, an analytics SDK, or any other third party — it goes to a server we operate ourselves and nowhere else. Nothing is sold or shared.

You can turn analytics off at any time in the app's Settings. Opting out stops new events from being sent and deletes the events already collected from your install.

Where your data lives

• On your device. Notes and attached photos or files are stored locally on your iPhone or iPad.
• In your iCloud. If you are signed in to iCloud, Folio syncs your data through Apple's CloudKit to your private iCloud database — storage that belongs to your Apple account, protected by Apple, and inaccessible to us. Apple's handling of iCloud data is described in Apple's own privacy policy.

Sharing notes

When you share a note, Apple's CloudKit sharing sends an invitation to the people you choose. Only invited participants can see that note. Sharing never passes through any server of ours, and you can stop sharing at any time from the note's share settings.

AI features

"Enhance with AI" runs entirely on your device using Apple Intelligence. The text of your notes is never sent to us or to any third party by Folio.

Notifications and Live Activities

Note reminders and Lock Screen Live Activities are scheduled and rendered on your device by iOS. The content shown (titles, previews, times) never leaves your device except via your own iCloud sync.

Photos and files

When you attach a photo or file, Folio receives only the item you explicitly pick — it has no access to the rest of your photo library or file system.

Children's Privacy

Folio does not knowingly collect any data from anyone, including children.

Changes to This Privacy Policy

If a future feature ever changes any of the above, this policy will be updated before that feature ships, with the effective date revised.
