<h1>PaperScreen Terms of Use</h1>
<p class="meta">
  App: <strong>PaperScreen</strong> (<code>com.devvratkalia.paperScreen</code>) &middot;
  Publisher: <strong>Dev_K</strong><br>
  Effective date: <strong>9 August 2026</strong> &middot;
  Contact: <a href="mailto:wekstuff@gmail.com">wekstuff@gmail.com</a>
</p>

<p>These terms are the agreement between you and <strong>Dev_K</strong> ("we", "us") covering your use of the PaperScreen app on Android, iOS, iPadOS and macOS. By installing or using PaperScreen, you accept them. If you do not accept them, please uninstall the app.</p>

<p>How we handle data is covered separately in the <strong>PaperScreen Privacy Policy</strong>, which forms part of these terms.</p>

<div class="box">
  <p><strong>Read this first:</strong> PaperScreen is a comfort and habit tool, not a medical device. It does not diagnose, treat or prevent any eye condition. See section 4.</p>
</div>

<h2>1. What PaperScreen does</h2>
<p>PaperScreen applies a paper-like display filter to reduce glare and harshness, and prompts you to take breaks — the 20-20-20 rule (every 20 minutes, look at something about 20 feet away for 20 seconds) and a stand-up reminder that defaults to once per hour. On macOS it can be controlled from the menu bar, and on all platforms it can start with your device and run in the background so your filter and schedule stay active.</p>

<h2>2. Eligibility</h2>
<p>You must be at least 13 years old (16 in some EEA countries) to use PaperScreen. If you are under the age of majority where you live, you may use it only with a parent or guardian's permission, and they accept these terms on your behalf. Only an adult may buy a subscription.</p>

<h2>3. Your licence</h2>
<p>We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use PaperScreen on devices you own or control, as permitted by the rules of the app store you installed it from. You may not:</p>
<ul>
  <li>copy, sell, rent, sublicense or redistribute the app;</li>
  <li>reverse-engineer, decompile or disassemble it, except where that right cannot be excluded by law;</li>
  <li>remove or obscure any copyright or ownership notices;</li>
  <li>circumvent the Pro paywall, tamper with subscription validation, or generate fake ad impressions or rewarded-ad completions;</li>
  <li>use the app to break any law, or in any way that interferes with another person's device or service.</li>
</ul>
<p>We own PaperScreen and everything in it — code, design, the glass interface, paper textures, name and logo. This licence gives you the right to use the app; it does not transfer ownership of anything.</p>

<h2>4. Health disclaimer — important</h2>
<p>PaperScreen is a general wellness and comfort tool. It is <strong>not</strong> a medical device and gives no medical advice.</p>
<ul>
  <li>The paper filter and break reminders may make long screen sessions more comfortable, but we make no claim that they prevent, treat or cure eye strain, dry eye, myopia, headaches, musculoskeletal problems or any other condition.</li>
  <li>The 20-20-20 rule and hourly standing reminders are widely recommended habits, not a prescription for you specifically.</li>
  <li>If you have persistent eye pain, vision changes, severe headaches, or any other symptom, see a qualified eye-care professional or doctor. Do not delay medical care because an app told you to take a break.</li>
  <li>If you are photosensitive or have a condition affected by changes in screen colour, brightness or contrast, check with your doctor before using display filters.</li>
</ul>

<h2>5. Reminders and background operation — what we can and cannot promise</h2>
<p>PaperScreen schedules reminders through your operating system. Mobile and desktop systems are allowed to delay, batch or suppress background work and notifications to save battery — and they do, especially under aggressive battery-optimisation settings, Focus or Do Not Disturb modes, or after a forced quit.</p>
<p>So: reminders may be late, or occasionally missed. <strong>Do not rely on PaperScreen for anything time-critical</strong> — medication, appointments, deadlines or safety. It is a nudge, not an alarm system.</p>
<p>Similarly, the paper filter may be suspended by the operating system in some contexts, including DRM-protected video, secure input fields, full-screen games, and system dialogs. That is the platform's decision, not a defect in the app.</p>

<h2>6. The free version and advertising</h2>
<p>The free version of PaperScreen is supported by ads served through Unity LevelPlay mediation, including banner, interstitial and rewarded formats. By using the free version you agree to see ads and to the advertising data collection described in the Privacy Policy.</p>
<p>We do not control the content of third-party ads and do not endorse the products advertised. If you see an ad that is offensive, misleading or broken, tell us at <a href="mailto:wekstuff@gmail.com">wekstuff@gmail.com</a> with a screenshot and we will report it upstream.</p>
<p>Rewarded ads grant temporary access to a feature in exchange for watching a video. Rewards have no cash value, cannot be exchanged or transferred, and may be changed or discontinued.</p>

<h2>7. PaperScreen Pro subscriptions</h2>
<p>Pro unlocks the full feature set — custom paper profiles, custom reminder intervals and schedules, advanced controls — and removes ads.</p>

<h3>Plans and billing</h3>
<ul>
  <li>Two plans are offered: <strong>monthly</strong> (<code>pro_monthly</code>) and <strong>yearly</strong> (<code>pro_yearly</code>). Current prices are shown in the app before you confirm, in your local currency.</li>
  <li>All billing runs through the Apple App Store or Google Play — whichever you bought from. We do not process payments and never receive your payment details.</li>
  <li>Subscriptions <strong>renew automatically</strong> at the end of each period unless you cancel at least 24 hours before it ends. Your store account is charged within 24 hours of the renewal date.</li>
  <li>If a free trial or introductory offer is included, any unused part of it is forfeited when you buy a subscription.</li>
</ul>

<h3>Cancelling and refunds</h3>
<ul>
  <li>Cancel any time in your store account settings — <em>App Store → Subscriptions</em> on Apple platforms, <em>Google Play → Payments &amp; subscriptions</em> on Android. Uninstalling the app does <strong>not</strong> cancel a subscription.</li>
  <li>After cancelling, Pro stays active until the end of the period you already paid for. It then reverts to the free, ad-supported version. Nothing you created is deleted, but Pro-only profiles stop applying until you resubscribe.</li>
  <li><strong>Refunds are handled by the store, not by us</strong>, under Apple's or Google's refund policies. We have no ability to issue or reverse a charge. Consumer withdrawal or cooling-off rights under your local law still apply and are not affected by this clause.</li>
</ul>

<h3>Price and feature changes</h3>
<p>We may change prices or move features between the free and Pro tiers. Price changes affecting an existing subscription take effect only at the next renewal, and the store will notify you and, where required, ask for your consent before charging the new price. We will not take away a feature you are currently paying for without telling you in advance and giving you a chance to cancel.</p>

<h2>8. Availability and updates</h2>
<p>We may update PaperScreen to fix bugs, follow new OS requirements, or add features. Your platform may install updates automatically. We may also change, suspend or discontinue the app or any feature — including ending support for an OS version or a device. If we discontinue the app entirely, we will stop new subscription sign-ups and let existing subscriptions run to the end of their paid period.</p>

<h2>9. Third-party services</h2>
<p>PaperScreen relies on the Apple App Store, Google Play, Google Play services and Unity LevelPlay/Unity Ads. Your use of those services is governed by their own terms and privacy policies. We are not responsible for their acts or failures.</p>

<h2>10. Disclaimer of warranties</h2>
<p>PaperScreen is provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the app will be uninterrupted, error-free, compatible with every device or OS version, or that reminders will always fire on time.</p>
<p>Some jurisdictions do not allow the exclusion of implied warranties, and statutory consumer guarantees — including under EU consumer law, the UK Consumer Rights Act, the Australian Consumer Law and India's Consumer Protection Act — apply regardless of anything in this section. Nothing here limits those rights.</p>

<h2>11. Limitation of liability</h2>
<p>To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, lost data or lost productivity, arising from your use of or inability to use PaperScreen — including any missed reminder or any health outcome.</p>
<p>Our total liability for any claim relating to PaperScreen is limited to the greater of (a) the amount you paid us for the app in the 12 months before the claim, or (b) USD 50.</p>
<p>Nothing in these terms excludes liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot be excluded by law.</p>

<h2>12. Indemnity</h2>
<p>You agree to indemnify us against claims, losses and reasonable legal costs arising from your misuse of the app, your breach of these terms, or your violation of any law or third-party right.</p>

<h2>13. Termination</h2>
<p>You may stop using PaperScreen at any time by uninstalling it (cancel any subscription separately, in the store). We may suspend or terminate your licence if you materially breach these terms — for example by tampering with subscription validation or faking ad impressions. Sections 3, 4, 10, 11, 12 and 16 survive termination.</p>

<h2>14. Apple-specific terms</h2>
<p>For copies obtained through the Apple App Store:</p>
<ul>
  <li>This agreement is between you and Dev_K only, not with Apple. Apple is not responsible for PaperScreen or its content.</li>
  <li>Apple has no obligation to provide any maintenance or support for PaperScreen.</li>
  <li>If PaperScreen fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever.</li>
  <li>Apple is not responsible for addressing any claim by you or a third party relating to PaperScreen, including product liability, legal or regulatory non-compliance, and consumer protection or privacy claims.</li>
  <li>If a third party claims PaperScreen infringes its intellectual property, Dev_K — not Apple — is responsible for the investigation, defence, settlement and discharge of that claim.</li>
  <li>You confirm you are not located in a country subject to a US Government embargo or designated as "terrorist supporting", and are not on any US Government restricted-parties list.</li>
  <li>Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.</li>
</ul>

<h2>15. Google Play</h2>
<p>For copies obtained through Google Play, these terms are between you and Dev_K only. Google is not a party and is not responsible for PaperScreen. Google Play's Terms of Service also apply to your download and any purchase.</p>

<h2>16. Governing law and disputes</h2>
<p>These terms are governed by the laws of the country in which the publisher has its principal place of business, without regard to conflict-of-law rules, and the courts of that jurisdiction have non-exclusive jurisdiction over disputes.</p>
<p>If you are a consumer, this does not deprive you of the protection of the mandatory consumer-law rules of the country where you live, and you may bring proceedings in your local courts where your law gives you that right.</p>
<p>Before starting formal proceedings, please write to <a href="mailto:wekstuff@gmail.com">wekstuff@gmail.com</a>. Most problems are faster to fix than to litigate.</p>

<h2>17. General</h2>
<p>These terms, together with the Privacy Policy, are the entire agreement between you and Dev_K about PaperScreen. If a provision is found unenforceable, the rest stays in force. Our not enforcing a term is not a waiver of it. You may not assign these terms; we may assign them as part of a transfer of the app, on notice to you.</p>

<h2>18. Changes to these terms</h2>
<p>We may update these terms. The effective date at the top will change, and material changes will be shown in the app before they take effect. Continuing to use PaperScreen after that means you accept the new terms; if you do not, uninstall the app and cancel any subscription.</p>

<h2>19. Contact</h2>

Two things worth acting on before you publish:

1. **Governing law (Terms §16)** — replace the "principal place of business" wording with a named country.
2. **macOS Screen Recording permission (Privacy §5)** — I documented it because most macOS display-tint techniques trigger it, and if PaperScreen requests it, an undisclosed request looks alarming to users. If your macOS implementation uses a colour-profile / gamma-table approach and never requests it, delete that bullet.
