Privacy Policy
Effective November 3, 2026
In short
Monthly does not collect, store, transmit, sell or share any of your personal information. Your notes stay in the folder you choose, and Flux0 never sees them.
Monthly (iPhone, iPad and Mac)
Your notes and images
Monthly reads and writes Markdown files and images in a folder you choose, on your device or in a cloud folder you already use (such as iCloud Drive). They never leave that folder because of Monthly. If the folder is synced, the sync is done by that service under its own privacy policy.
No accounts, analytics or tracking
Monthly has no sign-in, no servers, no analytics, no advertising and no third-party SDKs. It makes no network requests of its own and does not track you across apps or websites.
On-device settings
Layout preferences, such as how cells are zoomed, are saved on your device. Settings for a vault, such as how notes are named, are saved inside that vault's folder.
Crash reports
If you opt in to sharing analytics with app developers in your device's settings, Apple may share anonymous crash reports with us. We use them only to fix bugs.
This website

Changes
If this policy changes, we will update this page and its effective date.
