What happens when I set an alarm?
It runs in the open page on your device. The time, the sound, the light, the vibration, the wake-up task and the follow-up check are kept in the page only and are gone when you close it. Most sounds are generated in your browser; the two recordings (Construction Site and Heavy Traffic) are files from our own site. A room code is made on your device; if you save the code card, your browser downloads it as an image file to your device. Nothing is uploaded.
What does the offline copy store?
The first time you visit, your browser saves a copy of the site's pages, scripts and sound files (a service worker cache) so the alarm opens quickly and works without a connection. If you close the "install" hint, the site remembers that in local storage so it does not show it again. Neither contains anything about you.
Does heavysleeper.app show ads?
Yes. Some pages on heavysleeper.app show ads served by Google AdSense, a service of Google. Google is a third-party vendor, and Google and its advertising partners use cookies to serve ads on this site.
- Google's advertising cookies let Google and its partners show ads to you based on your visits to heavysleeper.app and/or other sites on the internet.
- Ads can be personalised (based on your earlier activity) or non-personalised (based on things like the page you are on and your general location).
- Third-party vendors and ad networks, as well as Google, may place and read cookies in your browser, or use web beacons or similar technologies, to collect information when ads are shown.
Google explains how it uses information from sites that use its services here: How Google uses information from sites or apps that use our services. How Google uses cookies in advertising is described on Google's advertising technologies page.
How can I turn off personalised ads?
You can turn off personalised advertising from Google at any time in Google Ads Settings.
You can also opt out of personalised advertising from many other third-party vendors at www.aboutads.info/choices or, in Europe, at www.youronlinechoices.eu. Turning off personalised ads does not remove all ads; you will still see ads, but they will not be based on your earlier activity.
You can also block or delete cookies in your browser settings. The alarm, the tasks and the sleep calculator keep working if you do.
How do you ask for consent in the EEA, the UK and Switzerland?
If you visit from the European Economic Area, the United Kingdom or Switzerland, you will see a consent message before advertising cookies are used or personalised ads are shown. The message comes from a consent management platform certified by Google and lets you accept, refuse or choose purposes and vendors one by one.
- If you do not consent, Google may still show non-personalised ads, using only the cookies or data that its policies allow for that, for example to limit how often you see an ad and to detect fraud.
- The consent tool stores your choice in your browser so it does not ask again on every page.
- You can change or withdraw your consent at any time with the "Privacy and cookie settings" link at the bottom of the page, or by deleting the cookies for heavysleeper.app in your browser.
What cookies and browser storage does the site use?
| What | Set by | Why | When |
|---|---|---|---|
| Advertising cookies (for example Google's ad cookies) | Google and its advertising partners | To show ads, measure them, limit repeats and prevent fraud; for personalised ads where you have agreed or where consent is not required | When a page with ads loads, subject to your consent choice |
| Consent choice | The Google-certified consent tool | To remember what you chose in the consent message | When you answer the consent message (EEA, UK, Switzerland) |
Install hint closed (hs-install-dismissed, local storage) |
heavysleeper.app, in your browser only | So the "add to home screen" hint does not come back | When you close the hint; until you clear site data |
Offline copy of the site (service worker cache shell-hs-…, pages-hs-…, audio-v1) |
heavysleeper.app, in your browser only | So the pages open quickly and keep working without a connection | On your first visit; replaced when the site is updated |
Browser storage set by heavysleeper.app stays on your device. We cannot read it, and it is not sent to our server. You can delete it by clearing your browser data for heavysleeper.app.
How do you count visitors?
We count visits with Cloudflare Web Analytics. It does not set cookies, does not use your browser storage and does not identify individual visitors. We only see totals, such as page views per page, referring sites, countries and device types. A small script from static.cloudflareinsights.com reports each page view to Cloudflare. Your alarm time, sound, task and answers are not included.
What do the server logs contain?
The site is hosted on Cloudflare. Like any web host, Cloudflare processes technical data such as IP addresses, browser type and the pages requested in order to deliver the site and protect it against attacks. We use this only to run and secure the site, not to identify visitors. Cloudflare's own handling of this data is described in the Cloudflare privacy policy.
Who is heavysleeper.app for, and what about children?
heavysleeper.app is a general-audience site for everyone who wants to set a loud alarm with light, vibration and a wake-up task, and plan their sleep. It is not directed at children under 13. Because there is no account, we do not ask anyone for a name, email address or other contact details to use the site, and we do not knowingly collect personal information from children. If you think a child has sent us personal information, for example by email, write to info@heavysleeper.app and we will delete it.
What is the legal basis, and what are my rights?
For visitors covered by the GDPR:
- Advertising cookies and personalised ads are based on your consent, given in the consent message. You can withdraw it at any time.
- Server logs, security and visitor counts are based on our legitimate interest in delivering a working, secure website.
- Your alarm settings, tasks and sleep times stay on your device and never reach us.
- Emails you send us are used only to answer you, and deleted when you ask.
You have the right to ask for access to, correction of or deletion of personal data about you, to object to processing, and to withdraw consent. Write to info@heavysleeper.app. For data that Google processes for advertising, you can also use the tools in your Google account and Google's privacy policy. You can complain to the Swedish Authority for Privacy Protection (IMY) or to the data protection authority in your own country.
Will this policy change?
If we change how the site uses data, we will update this page and the date below. If a change needs your consent, you will be asked again through the consent message.

Can I use HeavySleeper without personalised ads? Yes. Refuse personalised ads in the consent message, or turn them off in Google Ads Settings. You will still see ads, but they will not be based on your earlier activity.
