Terms of use

Last updated 12 September 2026. Tweaksy is provided by OptiCab Ltd.

The service

Tweaksy builds changes from your description and applies them in your browser. Changes affect how pages look and behave for you only. You are responsible for how you use them and for complying with the terms of the websites you use them on.

Acceptable use

Do not use Tweaksy to collect other people's personal data, bypass paywalls, logins or security measures, send spam, or interfere with a website's operation for other users. We may disable accounts used this way.

Subscriptions

Starter (£9.99 a month, up to 2 computers), Team (£15.99 a month, up to 10 computers) and Business (£29.99 a month, up to 50 computers) are billed monthly by Stripe and renew until you cancel. A 7-day free trial applies to new accounts; cancel before it ends and you are not charged. Cancel any time from your account via Manage subscription; access continues to the end of the paid period. A "computer" is a Chrome browser logged into your account.

Fair use

Monthly limits on new changes: Starter 150, Team 500, Business 1,000. Each account can also make up to 40 a day. A change built in Normal counts as 1; one built in Enhanced counts as 3. Changes you have already made keep running without using any up.

No warranty

Changes may not work on every page and may stop working when a site changes. The service is provided as is. Our liability is limited to the amount you paid us in the previous three months.
