Discover Daily ("the extension") is built to run entirely on your own device. This policy explains exactly what data it touches and why.
Browsing history (history permission).
The extension reads your browser's browsing history to compare it against
a local topic bank, so it can avoid recommending topics you've already
looked into. This comparison happens entirely inside the extension, on
your device.
Local storage (storage permission). The
extension stores the following locally in your browser, and it never
leaves your device except as noted under "Payment status" below:
Alarms & notifications. Used only to regenerate your daily topic list each morning and optionally notify you it's ready. No data is transmitted.
Checkout for Discover Daily Pro is handled by FastSpring (fastspring.com), a third-party merchant-of-record payment processor — purchasing opens FastSpring's own secure checkout page in a new browser tab; no payment card details ever pass through this extension.
To activate Pro features after purchase, you enter the email address you paid with into the extension. The extension sends that email address to a small server we operate (a Cloudflare Worker) solely to check whether it's associated with an active subscription, and receives back a simple yes/no answer. That server does not receive, store, or have any access to your browsing history, notes, or any other locally stored data — it only ever sees the email address you choose to enter and a paid/unpaid flag.
This email-check call is the only network call the extension makes besides the optional remote-configuration check below. See FastSpring's own privacy policy at fastspring.com/privacy for how they handle payment and billing information.
The extension may periodically check a small configuration file we host (to display announcements or enable/disable specific features) — no personal data or browsing history is included in this request.
Uninstalling the extension removes all locally stored data (topics shown, streaks, notes, settings, custom topic packs) from your device. There is no copy anywhere else, because none was ever created.
If this policy changes, the "Last updated" date above will be revised and, for material changes, noted in the extension's Chrome Web Store or Microsoft Edge Add-ons listing.
This policy applies to Discover Daily regardless of which browser or extension store you installed it through — Google Chrome, Microsoft Edge, or any other Chromium-based browser.
