Terms of Use

Effective 10 November 2026

These Terms of Use ("Terms") are an agreement between you and Pravit Vanadilok, an independent developer based in Thailand ("we", "us"), and they cover your use of the Duskmode iPhone app (the "App"). By downloading or using the App you agree to these Terms and to our Privacy Policy. If you don't agree, please don't use the App.

1. What Duskmode is, and what it isn't

Duskmode is a self-help tool that uses Apple's Screen Time features to block ("dim") apps you choose for a period you set. It is not a medical device and not a treatment for ADHD or any other condition. It does not give medical advice and does not replace a doctor, therapist or other qualified professional. Any mention of ADHD describes who the App is designed for, not a health claim.

2. Licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on Apple devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. You may not copy, modify, reverse engineer, resell or redistribute the App, except where the law allows it.

3. Subscriptions, free trials and introductory offers

Paid access. The App requires a Duskmode subscription (monthly or yearly). Prices are shown in the App before you buy, in your local currency and including any applicable taxes.
Billing. Payment is charged to your Apple Account when you confirm the purchase, or when any free trial ends.
Automatic renewal. Your subscription renews automatically at the same price and for the same length unless you turn off auto-renew at least 24 hours before the end of the current period. Your Apple Account is charged for renewal within the 24 hours before the current period ends.
Free trial. If a free trial is offered, it converts to a paid subscription when it ends unless you cancel at least 24 hours before then. Any unused part of a free trial is forfeited when you buy a subscription.
Introductory prices. A reduced first-period price, where offered, applies to the first period only. After that the subscription renews at the regular price.
Managing and cancelling. Go to Settings › [your name] › Subscriptions on your iPhone. Deleting the App does not cancel your subscription.
Refunds. Apple processes all payments and refunds. You can request a refund at reportaproblem.apple.com, and refunds are subject to Apple's policies.
Price changes. If we change the price, Apple will notify you in advance as its rules require. Where required, you will be asked to agree to the new price before it applies.

4. How blocking works, and its limits

Blocking relies on Apple's Screen Time framework and on your iPhone's settings, so we cannot guarantee that it always works. iOS updates, device restrictions, turning off Screen Time access, or using another device can stop or weaken a block. Calls, emergency features and apps you have marked as always allowed are never blocked by design. Do not rely on Duskmode in any situation where a failed block could cause harm.

5. Acceptable use

Don't use the App to break the law, to control another person's device without their consent, or to interfere with the App or its services. Only use it on devices you own or are allowed to manage.

6. Our content and your feedback

We own the App, its design and its content, and we keep all rights not expressly granted to you. If you send us suggestions, we may use them without any obligation to you.

7. Third-party services

The App relies on services from Apple, RevenueCat and TelemetryDeck, as described in the Privacy Policy. Their own terms govern their services.

8. Disclaimer

To the maximum extent the law allows, the App is provided "as is" and "as available", without warranties of any kind, whether express or implied. These include warranties of merchantability, fitness for a particular purpose and non-infringement. We don't promise that the App will be uninterrupted or error-free, or that it will reduce your screen time or improve your focus.

9. Limitation of liability

To the maximum extent the law allows, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, data, time or opportunities. Our total liability for any claim relating to the App is limited to the amount you paid for the App in the 12 months before the claim. Some places do not allow these limits, so they may not apply to you. Nothing in these Terms limits your rights as a consumer that cannot be waived under the law where you live.

10. Ending these Terms

You can stop using the App at any time by deleting it and cancelling your subscription. We may suspend or end your licence if you seriously breach these Terms. Sections 6 and 8 to 13 continue to apply after these Terms end.

11. Changes

We may update these Terms. We will change the date at the top, and if a change is significant we will tell you in the App before it takes effect. If you keep using the App after a change, you accept the new Terms.

12. Governing law

These Terms are governed by the laws of the Kingdom of Thailand. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring claims in your local courts.

13. Terms required by Apple

You and we both acknowledge that:

These Terms are between you and us only, not with Apple Inc. ("Apple"). We, not Apple, are solely responsible for the App and its content.
Apple has no obligation to provide any maintenance or support for the App.
If the App fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price (if any) for the App. To the maximum extent the law allows, Apple has no other warranty obligation for the App. Any other claims, losses, liabilities, damages, costs or expenses caused by any failure to conform to a warranty are our responsibility, to the extent they are not disclaimed in these Terms.
We, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your use of it. This includes product liability claims, claims that the App fails to meet a legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
If a third party claims that the App or your use of it infringes their intellectual property rights, we, not Apple, are solely responsible for investigating, defending, settling and discharging that claim.
You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated as "terrorist supporting", and that you are not on any U.S. Government list of prohibited or restricted parties.
You must comply with any applicable third-party terms when using the App.
Apple and its subsidiaries are third-party beneficiaries of these Terms. Once you accept these Terms, Apple has the right (and is deemed to have accepted the right) to enforce them against you as a third-party beneficiary.
