Terms of Service

Last updated 12 August 2026. Using a Nightshade app means accepting these terms, between you and Applied Science Group.

1. Nightshade is not a safety device

This is the most important term here. Nightshade estimates drowsiness from a camera. It can miss drowsiness entirely, and it can report drowsiness that is not there. Glasses, sunglasses, hats, masks, poor light, an unusual angle or an unusual face can all reduce or defeat it.

Never treat it as permission to keep driving, keep working, or stay awake. It does not replace rest, and it is not a medical device — it does not diagnose or treat anything, including any sleep disorder.

2. If you are driving

You are solely responsible for operating your vehicle safely and for obeying every law that applies to you, including hours-of-service rules and laws on mounting or using a phone while driving. If you feel drowsy, pull over. Set the app up before you move, not while you are moving.

3. Licence

You get a personal, non-exclusive, non-transferable licence to use the app. You may not reverse engineer, resell or redistribute it, except where the law says you may.

4. Trial, pricing and refunds

Every app includes a 30-day trial with detection enabled. Afterwards you may buy an annual subscription or a one-time lifetime unlock, or keep using the app free without detection. Purchases are processed and refunded by Apple or Google under their terms. Subscriptions renew until cancelled, which you do in your store account.

5. Fleet

Where an employer deploys Nightshade Fleet, that employer is the controller of the driver state data it receives, and their own policies govern its use. Fleet is licensed separately.

6. No warranty

The apps are provided "as is", without warranty of any kind. We do not warrant that detection will be accurate, uninterrupted, or that it will wake you.

7. Limitation of liability

To the fullest extent the law allows, Applied Science Group is not liable for any indirect or consequential loss, or for any injury, death, damage or loss arising from reliance on the app's output. Our total liability is limited to what you paid for the app in the twelve months before the claim. Some jurisdictions do not allow these limits, so they may not apply to you. Nothing here limits liability that cannot lawfully be limited.

8. Changes and termination

We may update these terms; material changes are announced in the app. We may suspend access if the terms are breached.

9. Governing law

These terms are governed by the laws of the jurisdiction in which Applied Science Group is established, without regard to conflict-of-law rules.
