Swedish law applies, but you keep the consumer protection of the country where you live.

Who provides the site?

heavysleeper.app is provided by Takreparation Skåne AB, Sparvgränd 6, 262 41 Ängelholm, Sweden (org.nr 556988-5931). Email info@heavysleeper.app, phone +46 760 061 969. By using the site you accept these terms.

How may I use heavysleeper.app?

You may use the alarm, the sounds, the wake-up tasks and the sleep calculator free of charge. You do not need an account.

Please do not:

copy the site, its code or its text and publish it as your own,
try to disrupt the site, overload it or get around its security,
use automated tools to download pages in bulk,
use the site for anything unlawful.

Can I rely on HeavySleeper as my only alarm?

No. A browser alarm rings only while the page stays open, visible and unlocked, the device stays awake and the sound is allowed to play. A closed tab, a locked screen, a low battery or a power-saving mode can stop it, and vibration does not work in Safari on iPhone. For work, travel or medication, never rely on the browser alarm alone: set your phone's built-in alarm as well.

Are the loud sounds safe for my hearing?

Use the lowest volume that wakes you. Do not play the alarm through headphones or with the speaker close to your ear. If others sleep nearby, warn them first.

Is HeavySleeper medical advice?

No. It is a tool for waking up, not a medical service. If you often sleep through alarms, feel very sleepy in the day or have trouble sleeping, talk to a doctor.

Who owns the content of the site?

The text, design and code of heavysleeper.app belong to Takreparation Skåne AB. You may link to any page. Please link rather than copy text to another website. If you believe something on the site infringes your rights, write to info@heavysleeper.app and we will look at it promptly.

Does the site show ads?

Yes. Some pages show ads from Google AdSense. Ads are provided by Google and its partners, not by us, and we do not endorse the products in them. How ads use cookies and how you can control them is explained in the privacy policy.

What guarantees do you give?

The site is provided free of charge and as it is. We work to keep it running and correct, but we cannot promise that it works on every device or browser, that it is always available, or that every result and fact is free of errors. We are not responsible if an alarm does not ring, rings too quietly or you sleep through it.

To the extent the law allows, Takreparation Skåne AB is not liable for any loss or damage arising from use of the site. Nothing in these terms limits rights you have as a consumer that cannot be limited by law.

Which law applies?

These terms are governed by Swedish law. If you use the site as a consumer, this does not take away the protection you have under the mandatory consumer laws of the country where you live.

Can these terms change?

We may update these terms, for example when the site gets new features. The date below shows the latest version. If you keep using the site after a change, the new terms apply.
