WallMark is a local-first iOS app for calculating picture hanging layouts and nail mark positions.
WallMark does not collect personal data.
The app does not use accounts, analytics, advertising SDKs, tracking SDKs, third-party SDKs, cloud sync, or external servers.
If you save a layout, the layout information you enter is stored locally on your device. This may include measurements, layout names, frame sizes, spacing, and hanger settings. This data is not sent to us.
WallMark does not track you across apps or websites.
WallMark is not directed to children and does not collect data from children.
WallMark does not request access to location, camera, photos, contacts, microphone, Bluetooth, health data, calendar, reminders, or notifications.
WallMark provides layout measurements only. It does not detect studs, judge wall material, select anchors, or guarantee installation safety. You are responsible for choosing appropriate hardware and installation methods for your wall.
