On the iPhone
Every entered dimension and conversion.
ArchMMMenu
Effective July 24, 2026
The calculation stays on your iPhone.
ArchMM does not need an account, a network connection, or a developer-operated service to convert a dimension.
Private by default
A focused tool should not create a data trail.
ArchMM does not collect personal information, send calculations to the developer, or include third-party advertising, analytics, behavioral tracking, or external data services.
Stored locally
Your selected scale and printer preset.
Nothing to sell
No account, advertising profile, analytics record, or personal-data sale.
The details
Only the information the conversion needs.
Information collection
ArchMM does not ask for your name, email address, location, contacts, photos, or other personal information.
On-device preferences
The selected architectural scale and printer preset may be stored locally so they are ready the next time the app opens. Entered dimensions are used only for the requested calculation.
Sharing and deletion
The developer does not receive, sell, rent, or share calculations or preferences. Deleting ArchMM removes its locally stored preferences.
Questions and changes
If data practices change, this policy will be updated before release. Privacy questions may be sent to brandon@brandonptdavis.com.
