Sixteen to One — Privacy Policy

Last updated: February 2026

The Short Version

We don't collect any of your data. Sixteen to One stores your preferences locally on your device. We never see them, and we have no way to access them.

Data Storage

Sixteen to One stores your ratio preferences and settings locally on your device using iOS's UserDefaults. This data never leaves your device, is not synced to iCloud, is not accessible to us, and is automatically deleted if you uninstall the app.

Data Collection

Sixteen to One does not collect:

Calculations

All coffee-to-water ratio calculations happen locally on your device. We do not send calculation data to servers, log what ratios you use, or track your brewing habits.

Third-Party Services

Sixteen to One does not integrate with any third-party analytics, advertising, or tracking services.

Children's Privacy

Sixteen to One does not knowingly collect information from children under 13. The app does not collect personal information from any user regardless of age.

Changes to This Policy

If we make changes, we will update the "Last updated" date above.
