Privacy policy

Last updated: October 2026

The short version: without an account, your customizations never leave your browser. With a free account, we store your email and your page settings so we can sync them — and nothing else. We don't sell personal data. Ever.

1. Using Dayblaster without an account

Your shortcuts, widgets, background and preferences are saved in your own browser (localStorage). They are not sent to our servers. Clearing your browser data deletes them.

2. Using Dayblaster with a free account

What we store: your email address and a copy of your page settings (shortcuts, widgets, preferences), so we can back them up and sync them across your devices.
Where: on Supabase infrastructure hosted in the European Union (Frankfurt).
Sign-in: by email link — we never see or store a password.
Deletion: email us at service@dayblaster.com and we will delete your account and all its data.

3. Location and weather

To show local weather and currency, the site estimates your location — either from your IP address (via third-party geolocation services) or, only if you approve the browser prompt, from your device location. You can also set your location manually. Location data is used on your device and is not stored on our servers beyond your own settings.

4. Third-party services we rely on

Vercel — hosts the site (standard server logs, e.g. IP addresses, may apply).
Supabase — stores account emails and synced settings (EU).
Google services — site icons (favicon service) and news headlines (Google News), fetched without sending them your identity.
Google Analytics: if you accept cookies, we load Google Analytics 4 to measure visits. The tag is not loaded until you accept, or until a previous accept choice is found in this browser. Decline keeps analytics off.
Payment provider — Pro purchases are processed by our merchant of record; card details never touch our servers.
Advertising and affiliate partners — free-tier pages may show ads, and some links are affiliate links (see our affiliate disclosure).

5. Cookies and local storage

We use browser localStorage for your preferences, your cookie choice, and, for signed-in users, an authentication token. A first-visit banner asks you to Accept or Decline analytics and advertising cookies. You can change that choice later with Cookie settings in the footer. We do not run cross-site tracking of our own. Google Analytics runs only after you accept.

6. Advertising cookies and Google AdSense

Free-tier pages may show ads from third-party vendors. Google is one of those vendors. This section follows Google's Required content: privacy policy help page and How Google uses information from sites or apps that use our services.

Third party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.

Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the Internet.

Users may opt out of personalized advertising by visiting Google Ads Settings or My Ad Center. To opt out of a third-party vendor's use of cookies for personalized advertising, visit www.aboutads.info/choices. Visitors in the European Economic Area can also use www.youronlinechoices.eu.

Google describes how it uses information collected from sites and apps that use its services, including AdSense, on How Google uses information from sites or apps that use our services.

This site uses Google Consent Mode. Advertising and analytics storage stay denied until you accept cookies. You can change or withdraw that choice at any time with the Cookie settings link in the footer.

7. The Dayblaster browser extension

Our optional Chrome extension has a single purpose: it replaces your new-tab page with Dayblaster. It requests no special permissions and collects, stores or transmits no data of its own — opening a new tab simply loads dayblaster.com, where everything in this policy applies.

8. Your rights

You may request a copy of the data we hold about you, correct it, or have it deleted — one email to service@dayblaster.com does it. We answer within 30 days, usually much faster.

9. Changes

If this policy changes materially, we'll update the date above and note it on the site.
