Terms of Service

Last updated: 26 April 2026

These terms cover your use of Blocker, a small Mac app published by Léo Mathurin (“we”, “us”). By installing or using Blocker you agree to them. If you don’t agree, please don’t use the app.

01The app

Blocker is a macOS application that turns off websites you choose by editing your Mac’s /etc/hosts file. To do that it installs a small privileged helper one time and asks for your administrator password. The helper runs locally on your Mac. Nothing about you or your blocklist is sent to us.

02Free trial

Blocker is a paid app with a 7-day free trial. During the trial you have full access to every feature. When the trial ends, the app stops blocking until you buy a licence. No charge is made until you choose to buy.

03The licence we grant you

When you buy Blocker we grant you a personal, non-exclusive, non-transferable, worldwide licence to install and use the app on Macs you own or control, for personal or internal business use, for as long as the version you bought continues to work. The licence covers free updates within that version line. You don’t buy the software itself; we still own it.

04What you may not do

You may not:

  • Copy, redistribute, sell, sublicense, or rent the app.
  • Reverse engineer, decompile, or disassemble it, except where the law expressly allows.
  • Remove or alter copyright, trade-mark, or attribution notices.
  • Use the app to do anything illegal, or to circumvent another person’s controls without their consent.

05Purchases and payment

We sell the paid version through Polar, our merchant of record. Polar processes the payment, charges any applicable VAT or sales tax, sends you the receipt, and appears as the seller on your bank or card statement. Polar’s terms and privacy policy apply to the transaction itself; these terms govern your use of the software once you’ve received your licence.

06Refunds

If something is wrong, write to support@getblocker.app within 14 days of purchase and we’ll refund you. Refunds are processed back through Polar to the original payment method. Statutory refund rights you may have under your local consumer law are not affected by this policy.

07Updates

We may release updates from time to time. Updates can add, change, or remove features. We’re not obligated to keep any particular feature, but we won’t take away the core blocking behaviour you paid for in the version line you bought.

08Privacy

Blocker has no accounts, no analytics, and no servers. Your blocklist and schedules stay on your Mac. See the Privacy Policy for the full picture.

09No warranty

Blocker is provided “as is”, without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We don’t guarantee that the app will block every page on every site, or that it can’t be circumvented — the FAQ describes the known trade-offs.

10Limitation of liability

To the maximum extent permitted by law, our total liability to you for anything related to Blocker is limited to the amount you paid us for it in the twelve months before the event giving rise to the claim. We are not liable for indirect, incidental, special, or consequential damages, lost profits, or lost data. Nothing here limits liability for death, personal injury, fraud, or any other liability that can’t be excluded under applicable law.

11Termination

You can stop using Blocker and uninstall it at any time. We may terminate your licence if you materially breach these terms — for example, by redistributing the app. On termination you must stop using Blocker and delete your copies. Sections 4, 9, 10, and 12 survive termination.

12Governing law

These terms are governed by the laws of France. Disputes will be brought before the competent courts of Paris, France, except where a different forum is required by mandatory consumer-protection rules in the country where you live.

13Changes to these terms

We may update these terms when the app changes or the law does. The “Last updated” date at the top reflects the current version. If we make material changes we’ll note them on this page; continuing to use Blocker after that date means you accept the new terms.
