Straighten the spine.
Sharpen the movement.
Wanna Be Ninja? turns your phone into a posture alignment scanner, a joint mobility journal, and a flexibility progress lab — so every stretch, squat and stand-up-straight moment actually adds up to something.
Four disciplines. One dojo.
Every tool below runs from a single phone camera and a bit of daily discipline — no lab equipment, no gym membership required.
Posture Camera & Joint Alignment Scanner
- Snap a side or front profile and overlay an interactive alignment grid across neck angle, shoulder level and pelvic tilt.
- Plot your range of motion on deep squats, forward folds and shoulder opens straight from a photo.
- Slide between before-and-after captures to watch real spinal alignment shift over weeks.
Mobility Routines & Stretch Timer
- Run guided interval timers for decompressing, neck relief and hip-opening sessions.
- Check off joint health micro-movements built for desk-bound days.
- Keep the streak alive with customizable reminders that nudge, not nag.
Flexibility Analytics & Body Metrics
- Calculate forward-bend and hamstring-extension angles directly on your progress photos.
- Log a stiffness & pain index across neck, low back, hips and ankles on an interactive heatmap.
- Read weekly reports on mobility minutes, posture gains and consistency.
Movement Diary & Calendar
- Plan morning rituals, evening cool-downs and foam-rolling sessions on a clean grid calendar.
- Unlock milestone badges for flexibility angles and streak length.
- Log stretches, scan posture and run timers fully offline, anywhere.
Drag the spine into alignment
A miniature taste of the real posture scanner — pull the slider and watch the plumb line, the tilt angle, and the ninja-status all respond live.
This is a simplified demo of the Posture Camera & Joint Alignment Scanner. In the app, the same logic runs on your actual photo — entirely on your device.
Built by people who used to slouch too
We're a small crew of ex-desk-hunchers, physiotherapy nerds and mobile builders who kept hearing the same complaint from ourselves and everyone around us: hours in a chair quietly rewrite your posture, and nobody tracks it the way they track steps or sleep. So we built the tracker we wished existed.
Our mission is simple — make spinal health and joint mobility something you can actually see, measure and improve, instead of a vague feeling that your back "isn't great." No clinics, no equipment, just a phone camera pointed in the right direction and a habit worth keeping.
Wanna Be Ninja? gives you a posture alignment scanner, a range-of-motion plotter, a stretch and mobility timer, a stiffness heatmap, and a weekly report that turns all of it into a story about your body — all logged in one calm, offline movement diary.
Stand taller. Move sharper. Wanna Be Ninja?
Your posture is yours. So is your data.
- 1. Information We Collect Wanna Be Ninja? is built to collect nothing. We do not request your name, email, location, or any account credentials, and the app contains no sign-up or login flow of any kind.
- 2. How We Use Information Because no information is gathered, none is analyzed, profiled, aggregated or sold. There is no server-side process that reads your posture photos, stretch logs, or streak history — there is simply no channel for that data to travel through.
- 3. Data Storage Every posture photo, alignment grid overlay, ROM measurement, stiffness entry and calendar log is stored exclusively in local storage on your device. Posture photos in particular are never uploaded, backed up to a cloud service, or transmitted anywhere — they are captured, measured, and kept on your phone alone.
- 4. Third-Party Services The app does not embed advertising networks, analytics SDKs, crash-tracking pixels, or any other third-party trackers. No data leaves the app to be shared with outside companies, because no collection pipeline exists in the first place.
- 5. Data Security Since your mobility journal, photos and metrics stay on-device, the meaningful security boundary is your phone's own lock screen and operating system safeguards. There is no remote database to breach, because none is maintained.
- 6. Children's Privacy Wanna Be Ninja? does not knowingly or unknowingly collect personal information from anyone, including children under 13. As no data collection mechanism exists app-wide, this applies equally to users of any age.
- 7. Your Control There are no user accounts to manage and nothing stored remotely to request. You retain full control at all times — clearing app data or deleting the app itself permanently removes every posture photo, log and streak from existence.
- 8. Changes to This Policy If our approach to privacy ever changes, an updated policy with a new effective date will be published within the app before any change takes effect. Continued use after an update constitutes acceptance of the revised terms.
- 9. Contact Questions about this policy can be sent to privacy@wannabeninjaapp.com.
