Privacy policy

Last updated 12 September 2026. Tweaksy is made by OptiCab Ltd, a company registered in England and Wales.

What the extension does with your data

Tweaksy lets you describe a change to a website in your account and applies that change in your Chrome. Your account holds your email, a hashed password, your changes (the code that makes the change, the text you typed to ask for it, the sites it applies to, and up to three previous versions so you can undo), any requests waiting to be built, any notes you save about a site, and the list of computers logged in with the names you gave them. The extension keeps a copy of your changes on each logged-in computer so they apply without contacting us.

What we send to our server, and why

When you ask Tweaksy to create or change something, the extension sends the following to our server: the text of your request, the address of the page, a structural snapshot of the page (element types, headings, button and field labels, table headers, class and id names, and short visible text fragments, capped at about 14,000 characters), and, if you pointed at an element, a copy of that element and its immediate surroundings with form values, hidden fields and anything that looks like a token removed. Any notes you have saved for that site are sent with it. We send this so an AI model can build the change. It is processed by our AI provider (Anthropic) under their API terms and is not used to train models. Snapshots are not stored; your request text and any notes are stored on your account as described above, and are deleted when you delete the change, the note, or the account.

The extension identifies itself with a device token issued when you log in, used to count seats on your plan and fair use per month. It checks in with our server every few minutes to fetch new changes; that check-in carries no page content and no browsing history. After a change is built, the extension checks once whether it applied and sends us a yes-or-no result. Page snapshots are only sent when a change is being built for a site you have asked to change.

Payments

Subscriptions are handled by Stripe. We never see your card number. We store your Stripe customer and subscription IDs on your account so we can keep it active and let you manage or cancel the subscription.

Permissions the extension asks for

• Read and change data on all websites: so your changes can apply on the sites you choose. Tweaksy only applies changes you created, only on the sites they match.
• User scripts: Chrome's name for the permission that lets an extension apply changes created by you.
• Storage: to keep your changes on your device.
• Tabs and scripting: to read the structure of the current page when you ask for a change, to let you point at an element, and to reload the page afterwards.

What we do not do

• We do not sell or share personal data.
• We do not track which sites you visit.
• We do not read pages unless you press the button asking us to.
• We do not accept API keys or passwords in site notes, and we ask you not to put them there.

Your rights

Email hello@tweaksy.app to ask what we hold about you or to have your account deleted. Logging out of the extension removes the copy of your changes from that computer. Changing your password logs out every computer and website session on the account.
