Privacy Policy
For the website getnoiseguard.com and the Chrome extension Noise Guard. Last updated:
This is the legally binding privacy policy. For a plain-language explanation, see Privacy at a glance.

2. This Website (getnoiseguard.com)
This website does not set analytics or marketing cookies and does not embed third-party tracking scripts (no Google Analytics, no Facebook pixel, nothing similar). The hosting provider processes technically necessary server log data on access (e.g. IP address, timestamp, page requested), as is standard for any web server. This data serves exclusively technical delivery and security purposes and is deleted automatically after a short time.
The language selection (language menu), if you deliberately change it, is stored locally in your browser (localStorage), not on a server.
3. Core Principle of the Extension: Local-First
Noise Guard processes all data exclusively locally in the browser. There is no Noise Guard server. The extension never sends content, settings, or usage data to us or to third parties at any point.
4. Chrome Web Store: Data Usage Disclosure
The Chrome Web Store requires every extension to explicitly disclose certain data categories. Here is the complete, honest answer for Noise Guard:
| Data category | Collected? |
| Personally identifiable information (name, address, email) | No |
| Health information | No |
| Financial information | No |
| Authentication information (passwords) | No |
| Personal communications (emails, chats) | No |
| Location data | No |
| Browsing history | No |
| User activity (clicks, mouse movement, keystrokes) | No |
| Website content (comment text, page elements) | Yes, see section 6, exclusively local, never transmitted |
Sale or transfer of data: Noise Guard does not sell user data, does not transfer user data to third parties, and does not use user data for purposes unrelated to the extension's core function. This is also technically impossible, since no data ever leaves the device.
5. What Is Stored Locally
All of the following data resides exclusively in chrome.storage.local on your device and can be fully removed at any time via "Settings → Privacy → Delete all data":
| Data type | Purpose |
| Settings (filter modes, levels, times) | Functionality |
| Domain of visited pages (no full URL, max. 200 entries) | Statistics dashboard, page retrospective |
| Custom filter terms, trusted/blocked people | Rules you entered |
| Progress badges & milestones | Display in the "Progress" section |
| Site preferences (settings per domain) | "Always treat this site this way" |
| Rule health (timestamp of last match) | Detecting ineffective custom rules |
6. Comment & Context Analysis
To detect toxic or aggressive comments, Noise Guard reads the visible text of comments on the currently open page and analyzes it in the browser's memory. This text is not permanently stored, not logged, and not transmitted, it only exists for the moment of analysis. The same applies to the optional context analysis of selected text via the right-click menu.
None of these analyses use a cloud AI or external service. Everything runs with local, heuristic rules directly in the browser.
6a. AI Detection (AI Disclosure Labels)
Noise Guard can optionally detect whether a visited page carries its own AI disclosure label (for example, YouTube's self-disclosure for altered or synthetic content, the disclaimer shown on Google AI-generated search answers, or an AI label on Instagram, Facebook, TikTok, or X). This works exclusively by looking for these labels already set by the platform itself and publicly visible, not by drawing its own conclusions from writing style or word choice. The check runs entirely locally in the browser, no page content is sent to a server. This feature is disabled by default and can be turned on in the extension's settings.
7. What Is NOT Processed
- No browsing history
- No full URLs or search terms
- No third-party cookies
- No IP address, no fingerprinting by the extension
- No advertising or usage profile
- No transmission to our servers or to third parties
8. Exception: Community Lists (only if enabled)
Noise Guard optionally offers the ability to query a URL you enter yourself for shared filter suggestions. Disabled by default. If enabled: clicking "Check now" fetches the entered URL via a simple GET request, no automatic background fetching, no local data is sent along. New entries only appear as suggestions and are only adopted after explicit confirmation.
This feature is the only place in the entire product that communicates with an external address not operated by us, on request.
9. Extension Permissions
| Permission | Purpose |
storage | Local storage of settings and rules |
host_permissions (content of visited pages) | Local detection of ads, comments, and page elements |
declarativeNetRequest | Blocking known ad/tracking domains, entirely local in the browser |
contextMenus | Right-click options (e.g. context analysis of selected text) |
activeTab | Access to the active tab when clicking the icon |
Every permission is used exclusively for the described function, not to read or transmit content to us.
10. Legal Basis (GDPR)
Local processing occurs to provide the functions you chose (Art. 6(1)(b) GDPR, performance of a contract at your request). Since no data leaves the device, no transfers to third parties arise that would require a separate legal basis.
11. Retention Period
Settings and custom rules remain stored until you change or delete them. Daily statistics reset automatically each day. Via "Settings → Privacy → Delete all data" you can remove everything completely at any time. Uninstalling the extension also deletes all stored data.
12. Your Rights Under the GDPR
Since all extension data resides exclusively locally on your device, you technically already have full access: access (export function in settings), rectification (changeable directly at any time), erasure (see section 11), restriction of processing (pause and exception features), and data portability (export as a file).
For questions about this website or your rights, you can contact us at any time via hello@getnoiseguard.com. You also have the right to lodge a complaint with the competent data protection supervisory authority.
13. Changes to This Privacy Policy
