Terms of Service — Njectify

Effective date: June 20, 2026 · Last updated: August 23, 2026

Acceptance

By installing or using the Njectify extension, you agree to these Terms. If you do not agree with any part of them, do not install or use the extension.


1. About Njectify

Njectify is a browser extension that lets you inject CSS and JavaScript into web pages, for visual and functional customization. The projects, rules, scripts, and styles you create are stored locally on your device, not on our servers.

It is developed independently by Diego Dias and distributed through the Chrome Web Store, where it went through Google's review process.


2. Permitted use

You may use Njectify to:

  • Customize the appearance of websites for personal or professional use.
  • Automate interactions on pages you are allowed to access.
  • Build, debug, and test scripts in your own or development environments.
  • Replace similar extensions (Tampermonkey, Stylus, Stylebot, and the like) with compatible scripts.

3. Prohibited use

You must not use Njectify to:

  • Inject malicious code, spyware, adware, or any harmful software.
  • Collect other people's personal data without their consent.
  • Carry out security attacks, unauthorised automated collection, or fraud.
  • Violate the terms of use of the sites where your scripts run.
  • Circumvent security, authentication, or content protection mechanisms.
  • Distribute scripts that harm other people.

Misuse is the sole responsibility of whoever does it. The extension is a neutral tool: you are the one who writes, imports, and runs the code.


4. Data and privacy

Njectify does not collect, store, or transmit personal data to our servers. There is only one situation, optional, where anything leaves your browser:

  • Google Drive sync: if you enable it, your projects are sent to your own account, into a private app folder (the drive.appdata scope). The extension never touches the rest of your files.

Everything else (rules, scripts, styles, settings, and history) stays exclusively on your device. The details are in the Privacy Policy, which forms an integral part of these Terms.


5. Extension permissions

If a permission is in the manifest, it is because a feature depends on it. The full list, with the reason for each one, is in the Privacy Policy. In short:

PermissionWhat it is for
<all_urls>You can create rules for any site, so the extension needs access to all URLs. A lightweight script checks whether a rule applies, and nothing is injected into pages with no rule created by you.
scripting and userScriptsInjecting CSS and JavaScript into the pages you configure.
activeTab and tabsIdentifying the active tab and applying the right rules.
storageKeeping projects, rules, and settings locally.
identityOnly if you connect Google Drive, to authenticate against your own account.
alarmsA daily internal cleanup routine.

6. Liability

Njectify is provided "as is", without express or implied warranties of continuous operation, freedom from errors, or compatibility with every site and browser version.

We are not liable for:

  • Damage caused by scripts you created or imported.
  • Blocks, bans, or restrictions imposed by third-party sites.
  • Data loss from uninstalling, clearing browser data, resetting the extension, or browser failures.
  • Incompatibilities with future versions of Chrome or other browsers.

We recommend exporting your projects periodically, in .njectify format, or keeping sync enabled.


7. Licence and ownership

Njectify is free. The source code is proprietary: you receive a personal, non-transferable licence to use the extension, not the right to redistribute it, resell it, or create derivative works from it.

The scripts and styles you write are yours. We claim no rights over the content you create with the tool. Third-party libraries bundled with the extension remain subject to their original licences.


8. Changes to these terms

These Terms may be updated as the extension evolves. The last-updated date at the top of this page indicates the most recent revision, and significant changes are announced through a notice inside the extension. Continued use after an update means you accept the new terms.


9. Governing law and venue

These Terms are governed by the laws of the Federative Republic of Brazil. The courts of the district of Rio de Janeiro – RJ are elected to settle any disputes arising from them, with express waiver of any other, however privileged.
