Privacy
Nothing to collect, nowhere to send it.
There is no server. No analytics, no accounts, no telemetry, no third parties. Every tool runs entirely inside your browser.
What leaves your machine
Nothing. The tools make no network requests at all, which is checked by a test that fails the build if any of them ever does. The one exception is buying: the checkout runs on Stripe's own pages, and this site never sees a card number.
What is stored, and where
Two tools keep something locally, in your browser's own extension storage. Draft Rescue keeps a short rolling copy of what you typed so it can hand it back. Cancel-By Reminder keeps the dates it found so it can remind you. Both are readable only by the extension, and switching that tool off deletes what it kept.
Your licence key
The key is verified against a public key inside the extension, using a signature. There is no activation server to contact, so the promise that nothing leaves your browser survives buying a licence. Keys are worked out from the purchase rather than stored in a database.
Permissions
Installing asks for nothing that shows a Chrome warning. Each tool requests the access it needs at the moment you switch it on, and it is handed back when you switch it off.
