Terms of use

Last updated 16 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

Current monthly plans are Starter (£9.99, up to 2 computers), Team (£29.99, up to 8 computers) and Business (£49.99, up to 20 computers; accounts opened before 18 September 2026 keep up to 50). Enterprise is quoted individually through Contact us. Plans are billed monthly by Stripe and renew until you cancel. Existing subscriptions keep their current price and purchased computer allowance unless you choose to change your subscription; earlier Team subscriptions keep up to 10 computers; the amount shown in Manage subscription and at checkout is the amount that applies to you. 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.

Marketplace purchases and creators

Creator applications are open. Paid purchases will open after our payment setup checks are complete. Included marketplace changes remain part of your Tweaksy plan.

When paid purchases open, each paid automation costs £1 as a one-off purchase for one Tweaksy account. A purchase gives that account permission to use the reviewed version on the website shown in the listing. It does not transfer ownership or permission to resell or redistribute it. An active Tweaksy plan and the Chrome extension are required to run it. A purchase does not include a subscription, a promise of future versions, or compatibility with every future website update.

Before checkout, you must expressly request immediate access and acknowledge that your 14-day cancellation right ends when the digital content is supplied. This does not affect your statutory rights if the content is faulty, not as described, or otherwise fails to meet the standards required by law. Contact hello@tweaksy.app with the order reference in your purchase history for help or a refund request. Tweaksy handles customer payments, support, refunds and disputes.

A refund removes the right to use the refunded automation and access to new copies. Remove any installed copies from your account. We may pause access to listings under a safety review. Withdrawing a listing from sale does not itself remove an existing customer's purchased version.

Anyone can create a free account and apply to become a creator. Approval is required for both the creator and each automation. Joining does not guarantee approval or sales. Only submit work you have the right to sell and license to Tweaksy for distribution to purchasers. Do not include confidential information, credentials, copied paid automations or code that breaks our acceptable-use rules. See the creator terms and earnings rules before applying.

Referral offers and account credit

Referral offers are available only when enabled in your account. The current offer gives an eligible new customer 25% off their first monthly subscription invoice and the referring account £2 of Tweaksy account credit after the referred customer's first successful paid invoice, a 14-day hold and review. The discount must appear at Stripe checkout before you pay. Later subscription invoices return to the price shown at checkout.

The new customer must claim a valid referral before their first payment and confirm their email address. One referral offer is allowed per new customer and it cannot be combined with another promotion. Self-referrals, duplicate accounts and artificial or misleading referrals are not eligible. Share links responsibly; do not send spam or imply that you represent Tweaksy.

Rewards are pending until checked and issued. Failed, refunded or disputed qualifying payments can prevent a reward or require review. A 14-day hold is an earliest review date, not a guaranteed payment date. Approved credit is applied to the referring customer's Stripe billing balance for future Tweaksy invoices; it is not a cash payout, card refund or creator earning. Your account shows pending and issued amounts separately. Contact hello@tweaksy.app if a reward needs checking.

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.
