Terms of Service for Night Shield

Last updated: November 5, 2026 · Effective: November 5, 2026

These Terms of Service ("Terms") govern your use of Night Shield, a blue light filter and screen dimmer for Android provided by Laxmi Solutions ("We", "Us", "Our") (package com.vi5hnu.nightshield). By using Night Shield, you agree to these Terms. If you do not agree, do not use the app.

1. The Service

Night Shield draws a colour filter and dimming layer over your screen to reduce blue light and brightness. It can be controlled from the app, a notification, a Quick Settings tile, home-screen widgets and a shake gesture, and can turn on and off on schedules you set. The free version is supported by ads; Night Shield Pro removes ads and unlocks additional features (Section 5). Night Shield works without an account. We may add, change or remove features over time.

2. Licence to Use

Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable licence to use Night Shield on devices you own or control. You may not copy, modify, distribute, sell, reverse-engineer or create derivative works of the app except as permitted by law.

3. Not a Medical Device

Night Shield is a comfort tool, not a medical device. It is not intended to diagnose, treat, cure or prevent any condition, including eye strain or sleep problems, and we make no promise about its effect on your eyes or sleep. Eye-break reminders are general suggestions. If you have concerns about your eyes or sleep, consult a qualified professional.

4. How the Filter Works on Your Device

Night Shield needs Android's "Display over other apps" permission. Android, other apps or the device maker may stop, block or limit overlays at any time, for example on system screens, in apps that block overlays, while installing apps or during screen recording, and battery savers may stop the filter or its schedules.
While the filter is on, colours on your screen change. Do not rely on Night Shield when accurate colour matters (for example, when editing photos or judging colours), and turn it off if it makes anything on screen hard to read.
Schedules, Auto sunset & sunrise and automation depend on Android delivering alarms and on the device's clock, location and power settings; we cannot guarantee they will run at the exact time.
Your settings are stored on your device and are not sent to us. You are responsible for keeping them, for example with Export settings (Pro) or Android backup. We are not responsible for lost settings, for example if you clear storage, lose your device or uninstall the app.

5. Ads, Night Shield Pro and the 24-Hour Trial

Ads. The free version of Night Shield shows ads served by Google AdMob. By using it, you agree to the display of ads. Ad-related data is handled as described in our Privacy Policy.
Free limits. The free version includes the filter, dimming and colour presets, with limits on some features (such as the number of schedules and per-app rules). The current free and Pro features are listed in the app before you buy.
Night Shield Pro is an optional one-time purchase that removes all ads in Night Shield and unlocks the Pro features listed in the app. It is not a subscription. It is sold and billed by Google Play and is subject to Google Play's terms. Its price, including any taxes, is set through Google Play and shown in the app before you buy.
Refunds are handled under Google Play's refund policy; we do not process payments or refunds ourselves. If a purchase is refunded, charged back or no longer listed by Google Play, Pro is removed: ads return, Pro features turn off, and settings that only Pro allows are reset to the free version's limits (for example, extra schedules beyond the free allowance are removed and custom per-app colours are cleared).
Pro belongs to the Google account used to buy it and can be restored on any device signed in to that account through Restore purchase.
The 24-hour Pro trial. You may choose to watch a rewarded ad to use Pro features for 24 hours. Ads are still shown during the trial. The trial is offered only while your device has a working internet connection and is granted only when the ad is watched to the end; a new trial can't be started while one is running. It is provided "as available" (an ad may not always be available), gives no lasting right, and ends early if the time can't be confirmed, for example after the device clock is changed. When it ends, settings that only Pro allows are reset as described above.

6. Automation

Night Shield Pro can be controlled by intents from automation apps such as Tasker, or from adb. Any app on your device that can send these intents can turn the filter on or off while Pro is active. You are responsible for the automations you set up. Android may block these requests in some situations, for example when the app has been force-stopped.

7. Acceptable Use

You agree not to: break any law or infringe anyone's rights while using Night Shield; interfere with or attempt to gain unauthorised access to the app or the services it relies on; circumvent any technical measures in the app, including ads, purchase checks or the Pro trial; or misuse ads or purchases (for example, through fraudulent or automated ad interactions, or tools that fake purchases).

8. Third-Party Services

Night Shield relies on third-party services, including Google Play (distribution, billing and reviews), Google AdMob (ads), Android's geocoder (for Auto sunset & sunrise) and, if you turn it on, Android backup. Your use of those services is subject to their own terms and privacy policies, and we are not responsible for them. Ads may link to advertisers' websites or apps, which have their own terms.

9. Disclaimers

Night Shield is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the app will be uninterrupted or error-free, that the filter, schedules or automation will always run, or that the app will meet your requirements.

10. Limitation of Liability

To the maximum extent permitted by law, Laxmi Solutions will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, settings, profits or goodwill, arising out of or relating to your use of (or inability to use) Night Shield. To the maximum extent permitted by law, our total liability for any claim relating to the app will not exceed the greater of (a) the amount you paid for Night Shield Pro, or (b) INR 500. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

11. Termination

You may stop using Night Shield at any time and uninstall it. We may suspend or discontinue the app or any feature at any time. Provisions that by their nature should survive termination (including Sections 3, 9, 10 and 12) will survive.

12. Governing Law

These Terms are governed by the laws of India, without regard to conflict-of-law rules. Subject to any mandatory rights you have as a consumer, the courts located in Rajasthan, India will have jurisdiction over disputes arising from these Terms.

13. Changes to These Terms

We may update these Terms from time to time. When we do, we will revise the "Last updated" date above. Continued use of Night Shield after an update constitutes acceptance of the revised Terms.
