Sugar-Free Days · Last updated: June 17, 2026
Sugar-Free Days ("the app", "we") is built to respect your privacy. This policy explains what data the app handles. In short: everything stays on your device, and we collect nothing.
None. Sugar-Free Days does not collect, transmit, or store any personal data on any server. We do not have accounts, logins, or a backend.
The app saves your progress — your start date, streak history, daily sugar and spending estimates, and settings — locally on your iPhone only. This information never leaves your device and is not accessible to us or anyone else. If you delete the app, this data is removed.
The optional one-time "Premium" purchase is processed entirely by Apple through the App Store. We do not receive your payment details. Purchase validation is handled by Apple and our in-app purchase provider (RevenueCat), which processes an anonymous purchase identifier solely to confirm your purchase. See RevenueCat's privacy policy and Apple's privacy policy.
If you enable the daily reminder, notifications are scheduled locally on your device by iOS. No notification data is sent to us.
The app does not knowingly collect any data from anyone, including children under 13.
If this policy changes, the updated version will be posted on this page with a new date.
