Effective date: 19 March 2026

This privacy policy explains how the "Home" browser extension and its backend service at hp.itst.net handle your data.

Data controller: Sascha A. Carlin · privacy@itst.net

1. What the Extension Does

Home is a browser extension for Chrome, Firefox, and Safari that replaces your new-tab page with a background photo, clock, search bar, daily focus field, and a quote. It fetches a daily photo and quote from our backend server and lets you search the web using the search engine of your choice.

2. Data We Use

2.1 Timezone

Your IANA timezone identifier (e.g. Europe/Berlin) is sent to our server once per day so we can serve the correct daily photo and quote for your calendar date. It is used only for cache keying and is not stored beyond the cache lifetime.

2.2 Photo Category

If you choose a photo category (e.g. "forest", "ocean"), that keyword is sent to our server as a query parameter to fetch a matching image from Pexels. It is not logged or stored beyond the cache lifetime.

2.3 Screen Dimensions

Your screen width and device pixel ratio are included in the image URL requested from the Pexels CDN so you receive an appropriately sized image. These values are not sent to our server.

2.4 Server Logs

Our server records abbreviated log entries for each request. IP addresses are anonymized by zeroing the last two octets (e.g. 11.22.33.44 becomes 11.22.0.0). Each log entry contains:

Log files are rotated and deleted daily.

3. Data We Do NOT Collect

4. Data Stored on Your Device

The extension stores small amounts of data locally in your browser:

Storage Contents Retention
browser.storage.sync Your preferences (search engine, photo category, focus text) Until you change them or uninstall the extension
browser.storage.local Cached photo metadata and daily quote Auto-deleted daily
Cache API Cached background image Auto-deleted daily

browser.storage.sync may be synchronized across your devices by your browser vendor (Google, Mozilla, or Apple) according to their own privacy policies. We have no access to this synchronized data.

Uninstalling the extension removes all locally stored data.

5. Third-Party Services

5.1 Pexels (Canva Pty Ltd)

We use the Pexels API to fetch daily background photos. When a photo is requested, our server sends the photo category and orientation preference to Pexels. Pexels' CDN delivers the image directly to your browser.

5.2 Your Search Engine

When you perform a search, your browser navigates directly to the search engine you selected (e.g. DuckDuckGo, Google, Bing, Brave). We are not involved in this request and have no access to your search queries. The search engine's own privacy policy applies.

5.3 Browser Vendor

Your browser vendor (Google, Mozilla, or Apple) may synchronize the preferences stored in browser.storage.sync to their servers. This is governed by your browser vendor's privacy policy, not ours.

6. Legal Basis for Processing (GDPR Art. 6)

We process the limited data described above on the basis of legitimate interest (Art. 6(1)(f) GDPR):

7. Data Retention

Data Retention
Server-side photo/quote cache 2 days
Server logs (anonymized IPs) 1 day (rotated daily)
Client-side cache (photos, quotes) Auto-deleted daily
Client-side preferences Until changed by you or extension is uninstalled

8. Your Rights

Under the GDPR, you have the right to:

Given the minimal and anonymized nature of the data we process, there is generally no personal data to access or delete. If you have questions or wish to exercise your rights, contact us at privacy@itst.net.

You also have the right to lodge a complaint with a data protection supervisory authority.

9. Data Security

10. International Data Transfers

Our backend server is located in Germany (EU). We do not transfer your data to countries outside the EU/EEA.

Background images are delivered by Pexels' CDN, which may serve content from servers in various countries. This is governed by Pexels' own privacy policy.

If you use browser.storage.sync, your browser vendor may store synced preferences on servers outside the EU, subject to their privacy policy.

11. Children's Privacy

The extension does not knowingly collect any personal data, including from children. Since no accounts or personal information are required to use the extension, no age verification is necessary.

12. Changes to This Policy

We may update this policy from time to time. Changes will be reflected by an updated effective date at the top of this document.
