Terms of Service

1. Acceptance of these terms

These Terms of Service ("Terms") govern your use of the Day21 - Clean Social Feed browser extension ("the extension") and this website, published by Day21 ("we", "us"). By installing or using the extension, or by using this website, you agree to these Terms. If you do not agree, do not install or use the extension. You must be old enough to form a binding agreement where you live in order to use it.

2. What the extension is

The extension changes how pages look in your own browser: on the social platforms you enable, it hides ads, sponsored posts, suggested content, and interface clutter you choose to hide. It runs locally, is currently free to install and use, and does not require an account.

The extension only affects what is displayed on your device. It does not change anything on the platforms themselves, does not post, follow, like, or interact on your behalf, and does not hide anything from anyone but you.

3. Platform terms

The extension works on websites operated by third parties. Your use of those websites remains governed by their own terms of service and policies, and you agree to use the extension only in ways those terms allow.

We are an independent publisher. We are not affiliated with, sponsored by, or endorsed by any social platform, and nothing about the extension implies otherwise. All platform names and trademarks belong to their respective owners.

4. How hiding works, and its limits

Platforms change their pages often. Something you asked the extension to hide may occasionally appear, and something you wanted to see may occasionally be hidden. Debug mode in the extension's settings marks most of what would be hidden instead of hiding it (a few items are simply shown), so you can check. You can pause the extension, turn any switch off, or disable a site at any time.

5. License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the extension for your own use. You may not resell the extension or misrepresent its origin. The extension and this website, including their design and code, remain our property.

6. No warranty

The extension and this website are provided "as is" and "as available", without warranty of any kind — express or implied, including but not limited to fitness for a particular purpose, non-infringement, or uninterrupted operation. Features may stop working at any time without notice when platforms change.

7. Limitation of liability

To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or exemplary damages, nor for any loss of data, profits, or goodwill, arising from your use of (or inability to use) the extension or this website. Our total aggregate liability shall not exceed the amount you paid us for the extension — which, for a free product, is zero. This limitation does not apply to liability that cannot be limited or excluded under applicable law, including liability arising from our gross negligence, willful misconduct, or fraud.

8. Changes to the extension and these terms

The extension's features and pricing may change over time. We may update these Terms by posting a new version on this page with an updated effective date; continued use after a change constitutes acceptance. We may discontinue the extension at any time.

9. Termination

You may stop using the extension at any time by uninstalling it. We may terminate or suspend the license in section 5 if you breach these Terms.

10. Governing law and venue

These Terms are governed by the laws of the State of New York, United States, without regard to its conflict-of-law provisions. If you have a dispute with us, please contact us first at day21dev2026@gmail.com — we make a genuine effort to resolve issues informally. Any dispute not resolved informally shall be brought exclusively in the state or federal courts located in New York State, and you consent to the personal jurisdiction of those courts.

11. General

If any provision of these Terms is held unenforceable, the remaining provisions stay in effect. These Terms are the entire agreement between you and us regarding the extension and this website.
