Mull is built to be private by design. This page explains exactly what that means, in plain language, with no legal jargon hiding the details.
When you set a financial goal in Mull (for example, a trip, a home down
payment, or a debt payoff target), that information — your goal type,
target amount, destination if applicable, target date if you set one,
and your progress — is saved using your browser's built-in local
storage feature (chrome.storage.local). You can run more
than one goal at a time; each is stored the same way, independently.
If you choose to fill out your optional profile, Mull also stores your income, your itemized needs (like rent or insurance), and your guilt-free spending amount — again, only in your browser's local storage. This section is entirely optional; Mull's core checkout feature works fully without it.
If you log money you've saved toward a goal outside of Mull (for example, a manual bank transfer), that entry — the amount, an optional note, and the date — is stored locally too. This is information you choose to enter yourself; Mull has no way to verify it and does not connect to any bank account.
When you tap "Mull it — decide tomorrow" on a specific product, Mull saves that product's name, price, and page link to your local Mulling List, along with a reminder time roughly 24 hours later. This is the one case where Mull does store information tied to something you were looking at — and it only exists because you explicitly chose to save it for later. You can view, revisit, or clear these saved items yourself at any time from the settings page.
All of this — your goals, your profile, your progress, and anything in your Mulling List — lives entirely on your own device. None of it is sent to Mull, to any server we operate, or to any third party. We have no ability to see, access, or retrieve this information, because it never leaves your browser.
If you uninstall the extension or clear your browser's extension storage, all of this data is permanently deleted. We cannot recover it, because we never had it.
Mull's popup activates when you click an "Add to Cart," "Reserve," or similar purchase-intent button on a supported shopping or travel site. To show you the product name and price, the extension reads this information directly from the webpage you are already viewing in your own browser.
In most cases, this information is used only to display the popup to you, in that moment, on your device — it disappears once the popup closes. The one exception is if you choose to tap "Mull it — decide tomorrow," in which case the product name, price, and link are saved to your local Mulling List as described above, until you act on it or clear it yourself. None of this is ever transmitted to Mull or stored on any server we operate.
Mull currently contains no affiliate links anywhere in the extension. Nothing you click today earns Mull a commission of any kind, and Mull earns $0 in revenue right now. The current focus is entirely on making Mull useful and available to as many people as possible — not on monetizing it.
That may change in the future. If Mull ever partners with a platform such that a link could earn a commission, that link will always be clearly labeled before it goes live — never quietly switched on. Any such commission would come only from a purchase or sign-up you choose to complete, at no extra cost to you, and would never be based on or connected to any personal data.
When you click a link inside the Mull popup or settings page to visit a retailer, financial platform, or comparison site, you leave Mull's extension and go to that third party's own website. That site's own privacy policy and data practices apply once you're there — Mull has no visibility into or control over what happens on their site.
Mull requests only the browser permissions necessary to detect purchase-intent buttons on supported shopping and travel sites and to display the popup. These permissions are used solely for that function and not for any other purpose, including tracking, analytics, or advertising.
If Mull's data practices ever change — for example, if a future feature requires storing information outside your device, or if affiliate links are introduced — this page will be updated and the date at the top will reflect the change. We will not make material changes that reduce your privacy without clearly communicating them here first.
