Void — Dark Mode for Safari
Effective Date: July 22, 2026 · Last Updated: July 22, 2026
Welcome to Void ("we," "us," "our," or the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard information when you use Void — a Safari dark-mode extension and companion macOS settings application.
Void is designed to be privacy-first. Dark-mode processing happens on your device. We do not operate a Void account system, and we do not send your browsing history or page contents to Cyborgate servers for analysis or advertising.
By installing or using Void, you acknowledge that you have read and understood this Privacy Policy. If you do not agree, please do not use the App or extension.
Void applies dark themes to websites you visit in Safari by injecting CSS and related styling logic into web pages, based on your settings. You can:
Void processes limited information needed to provide dark-mode functionality. Processing is local to your Mac unless you contact us separately by email.
| Data | Where Stored | Purpose |
|---|---|---|
| Global enable/disable, selected theme, filter adjustments | Safari extension storage & shared App Group on your Mac | Remember how you want dark mode to look and behave |
| Site hostnames (e.g. example.com) and per-site overrides | On-device only | Allow, disable, or customize dark mode per website |
| Custom themes you create (colors, image filters) | On-device only | Store your personal theme presets |
| Optional notes you attach to a site entry | On-device only | Let you label or remember site-specific preferences |
To restyle a page, Void's content scripts run in Safari and may read DOM structure, CSS, and related page resources on the current tab. This analysis is performed locally in Safari so themes can be applied correctly.
On-device data is used solely to:
If you email us for support, we use the information you choose to send (such as your email address and message) only to respond and resolve your request.
Data remains on your device until you change or delete it, uninstall Void, or reset Safari / extension data. Support emails are retained only as long as needed to handle your inquiry and meet legal obligations.
We do not sell personal information. Void does not share your site lists, themes, or browsing activity with third parties for marketing.
Limited disclosure may occur only if required by law, to protect our rights and users, or if you explicitly instruct us (for example, by attaching logs in a support email).
Apple provides Safari, extension APIs, and the Mac App Store infrastructure under Apple's own privacy practices. Those services are not controlled by Cyborgate.
We design Void so sensitive work stays local. Settings are stored using platform-provided storage mechanisms on macOS/Safari. No method of electronic storage is perfectly secure, but because Void does not upload browsing data to our servers, the primary risk surface for your site preferences is physical or account access to your Mac.
Protect your Mac with a strong password or biometrics, keep macOS and Safari updated, and only install software from trusted sources.
| Action | How |
|---|---|
| Disable Void on a site | Extension popup or Sites list in the macOS app |
| Turn Void off entirely | Safari → Settings → Extensions, or disable in the Void app |
| Clear site list / reset preferences | Edit or remove entries in the Void Sites / Themes UI |
| Remove all Void data | Uninstall the Void app and disable/remove the Safari extension |
| Privacy questions or deletion help | Email contact@cyborgate.uk |
Void is a general-purpose productivity utility and is not directed to children under 13 (or the applicable age of digital consent in your region). We do not knowingly collect personal information from children through Void. If you believe a child has provided personal information via a support email, contact us and we will delete it.
Void runs on your Mac. Because core product data stays on-device, Void does not transfer your site lists or page content to Cyborgate for processing. If you contact us by email, that correspondence may be processed where our support systems operate.
Where applicable laws grant you rights of access, correction, deletion, restriction, portability, or objection, you may exercise them by contacting contact@cyborgate.uk. Because Void keeps preferences on your device, the most effective way to delete product data is usually to clear settings or uninstall the app/extension.
We do not sell personal information as defined by the California Consumer Privacy Act (CCPA), and we do not share personal information for cross-context behavioral advertising.
Legal bases for any limited processing of support communications include legitimate interests (responding to you) and/or consent where required.
We may update this Privacy Policy to reflect product, legal, or operational changes. When we do, we will revise the "Last Updated" date at the top of this page and post the new policy at the same URL. Continued use of Void after changes become effective constitutes acceptance of the updated policy.
