Privacy Compass & Level

Privacy Compass & Level is three precision instruments in one beautifully simple app — a compass, a bubble level, and a flat surface level — built to work entirely on your device.

Designed for privacy first: no ads, no trackers, no analytics, and no accounts. In fact, the app has no internet permission at all, so nothing you do can ever leave your phone.

TOOLS
• Compass — a smooth, realistic dial showing your heading and 16-point direction. Turn on True North to correct for magnetic declination, and optionally see your coordinates.
• Bubble level — two spirit-level vials for leveling edges: stand the phone on its short or long edge and read the tilt to a tenth of a degree.
• Surface level — a bullseye level to lay the phone flat on any surface, with a firm haptic tick the moment you reach level.

CALIBRATION
• Compass calibration — your phone's magnetometer can read a few degrees off. Line the phone up against a real compass or another trusted reference and correct it once. The offset stays on your device.
• Case calibration — phone cases and camera bumps can make a phone rest slightly tilted. Calibrate once and the surface level treats your true-flat position as zero.

FEATURES
• True North with automatic magnetic declination
• Optional coordinate display (on-device only)
• Firm haptic feedback the moment a reading reaches level
• Smooth settling animation you can toggle on or off
• Light and dark themes, or follow your system
• Clean, skeuomorphic instrument design

PRIVACY
• No ads, no tracking, no data collection
• No internet access — enforced by Android, not just promised
• Approximate location is used only on your device, only if you enable True North, and is never stored or sent

For general and hobbyist use. Sensor readings depend on your device and surroundings; do not rely on the app for navigation, construction, or safety-critical purposes.
