Questions, answered plainly.

Yes. The toolbar icon opens the panel, which lists all eight tools with a switch beside each. Switching one off stops it in every tab already open, with no reload, and withdraws its code from the browser rather than leaving it loaded and idle. One more switch pauses everything on the site you are looking at and leaves the rest of the web alone.

Yes. Sites built from custom elements render their fields inside shadow roots, which retargets events and hides them from naive checks. Every Sidecar extension resolves the real element through the composed event path, and that behaviour is covered by tests that drive a real browser.

No. There is no server, no analytics, no crash reporter and no identifier attached to you. The extensions make no network requests at all, so there is nowhere for data to go even in principle.

Each extension is sold on its own, or as part of a bundle. The Gmail Toolkit (Attachment Reminder, Draft Rot Tracker and Cancel-By Reminder) is priced together, and the full eight-extension set is priced as one bundle at a discount to buying them separately. There is no subscription: every purchase is a one-time payment, with no account and no recurring charge. Payment is handled by Stripe, who act as merchant of record and take care of sales tax and VAT wherever you are.

Chrome, Edge and Brave on macOS and Windows, using Manifest V3. Firefox and Safari builds are planned.

No. Nothing in the catalog links to a bank, a card, or any account anywhere. Cancel-By Reminder finds renewal dates by reading subscription wording in emails you open, which is the whole reason it exists as an alternative to finance-linked subscription trackers.

No. Every detection is deterministic pattern matching that runs locally in your browser. That makes them predictable: the same message behaves the same way every time, and there is no model to send anything to.

Not yet. Review takes a while, so for now it loads from a folder instead: the install guide on the home page walks through it, and it takes about a minute, once, for all eight tools. Buying works the same either way, because the licence is a key rather than anything tied to a store account.

Every extension runs in full for 14 days with nothing held back, because a tool that only interrupts you a few times a month cannot be judged in an afternoon. When the trial ends the extension stands down and stops assisting until a key is added. It says so plainly rather than going quiet: the panel opens once to explain, and nothing you had saved is touched. Pasting a key puts it straight back to work.

In the panel, which is the toolbar icon the extension installs. It opens by itself the first time. Expand the licence line, paste the key, press Activate. One paste switches on exactly what you bought, whether that is one tool or all eight.

One extension containing eight tools. It used to be eight separate installs, which meant anyone buying the bundle unzipped and hand loaded eight folders before they could paste a key. Now there is one download and one panel, and the licence decides which tools switch on. Pricing did not change: you can still buy a single tool for $2.99.

No, and this was the reason to be careful about merging. Installing asks for nothing that shows a permission warning. Each tool asks for what it needs at the moment you switch it on, and hands it back when you switch it off. If Timezone Peek is the only thing you keep, nothing ever asks about Gmail.

Nothing. A tool you have not bought runs during the 14 day trial and then stands down, and a tool you switch off has its code withdrawn from the browser entirely rather than left loaded and idle. You can switch off anything you are not using at any time.

No, and that is the reason the key is as long as it is. The key carries its own cryptographic signature, and the extension checks that signature against a public key inside itself. There is no activation server, so the promise that these extensions make zero network requests survives buying one.

Go to Find my licence key and enter the email you paid with. The same key comes back. Keys are derived from the purchase rather than stored in a database, so there is no record to lose and nothing to reset.

Yes. Every extension ships unminified, and the detection logic is kept in its own file separate from the browser integration, so it can be read and checked without digging.

Its code is withdrawn from the browser and anything it kept locally is deleted. Nothing survives elsewhere, because nothing was ever stored anywhere else. Uninstalling the extension removes what all eight kept.
