Frequently Asked Questions
Everything you need to know about Slouch Sniper
How does Slouch Sniper work?
Slouch Sniper uses your webcam and on-device AI to detect your posture in real-time. When you slouch, it gently dims your screen as a subtle reminder to sit up straight. The moment you sit tall again, the screen returns to normal. Posture detection runs on your device, and your live video is never streamed or recorded.
Is my privacy protected? What happens to my webcam data?
Yes. Posture detection runs on your computer, and your live video is never streamed or recorded. No photos leave your computer unless you choose to share them to help train the model, and you can stop sharing anytime in Settings. Our privacy policy lists what the app sends, such as account checks, usage statistics, and crash reports.
Which devices and platforms are supported?
Currently, Slouch Sniper is available for Windows and Apple Silicon Macs (M1, M2, M3, and newer). It works with any built-in or external webcam—no wearable device is required. We're still working on Intel Mac and mobile support. Sign up for our newsletter to be notified when new platforms launch.
How much does it cost? Is there a subscription?
Slouch Sniper is a one-time $19 purchase for a lifetime license. One payment, yours forever—no subscriptions, no recurring fees.
Is there a free trial?
Yes. Download the app and use it free before you pay: 7 days on Mac (the trial starts when you create your account in the app) and 3 days on Windows. To keep using it afterwards, it's a one-time $19 purchase—no subscription.
Will this drain my battery or slow down my computer?
Not at all! Slouch Sniper is designed to be extremely lightweight and efficient. The posture model runs on-device a few times per second and uses less energy than Spotify, so it won't slow down your computer or noticeably affect battery life.
How accurate is the posture detection?
Our AI model has been trained on thousands of posture examples and achieves high accuracy in detecting slouching. It learns your neutral posture when you first start and adapts to your unique sitting position. The detection is sensitive enough to be effective but not overly strict, so you won't get false alerts.
Can I customize how the app works?
Yes! You can adjust the sensitivity of slouch detection, customize the screen dimming intensity, set quiet hours when you don't want notifications, and track your posture statistics over time. The app is designed to fit your workflow.
Will this actually help improve my posture long-term?
Yes! Slouch Sniper works through gentle, consistent reminders that help you build better posture habits over time. Most users report noticeable improvements within the first few weeks, including reduced back pain, less fatigue, and subconscious posture awareness even when not using the app.
