Fermentory — Privacy Policy

Effective date: 5 June 2026

Fermentory does not collect, transmit, sell, or share any of your data. Everything the extension stores stays locally in your own browser, on your device. There are no servers, no accounts, no analytics, and no tracking.

What Fermentory handles, and where it stays

When you visit a web page, Fermentory reads the page's text in your browser to detect whether a homebrewing recipe is present. This processing happens entirely on your device and the page content is not sent anywhere. If no recipe is found, nothing is kept.

When you choose to save a recipe or use a feature, the following is stored locally using the browser's chrome.storage.local API (on your device only):

• Saved recipes and their ingredients
• Your settings (e.g. metric/imperial preference, default batch size)
• Brew journal entries (gravities, dates, notes) — Pro feature
• Ingredient inventory — Pro feature
• Your Pro license key, if you have activated one

You can view, edit, and delete any of this from within the extension at any time.

What Fermentory does NOT do

• It does not send your data to us or to any third party.
• It has no analytics, telemetry, tracking pixels, or advertising.
• It requires no account and no sign-in.
• It does not read or store data from pages where no recipe is detected.

Permissions, explained

• Host access (all sites): required so the extension can read the text of the page you are currently viewing in order to detect a recipe. Detection runs locally; no page content leaves your device.
• Storage: used to save your recipes, settings, and preferences locally in your browser.

Pro licenses and external links

The free version is fully usable. The optional one-time Pro upgrade and any tips are both handled through Payhip. These links only open when you click them, in a normal browser tab, and Payhip's own privacy policy then applies. Your Pro license key is validated locally inside the extension — activating Pro does not contact any server or send us any information.

Data retention and deletion

Because all data is stored locally, you control it entirely. Removing a saved recipe deletes it. Using "Clear all saved recipes" in Settings, or uninstalling the extension, removes all stored data. We keep no copies because we never receive any.

Children

Fermentory is a tool for homebrewers and is not directed at children.

Changes to this policy

If this policy changes, the updated version will be published at this URL and the effective date above will be revised.
