Description

This PR adds the following macOS entry points for the win-back offer:

• modal message on the first day of eligibility
• badge in the ‘more options’ menu
• badge in the preferences sidebar
• updated ‘purchase subscription’ preference pane
• updated ’subscription settings’ preference pane
• partial support for NTP badge (see Notes at the bottom)

Testing Steps

1. enable feature flag: Debug > Feature Flag Overrides > VPN > winBackOffer
2. simulate churn via Debug > Win-back Offer > Simulate Churn
3. override Today’s date via Debug > Win-back Offer > Override Today’s date so that it’s 3 days after churn date (e.g. churn date is Oct 10, offer will start on Oct 13(

• After you restart, you should see the launch modal for the offer.
• You should also see the “Save 25%” badge in the ‘more options’ menu
• You should see the same badge in the preferences sidebar
• If you have no active subscription, you should see a variant of the ‘purchase subscription’ view on the preferences detail pane
• if you have an active subscription, you should see a variant of the ‘expired subscription’ view on the preferences detail

Impact and Risks

None, everything is behind feature flag

What could go wrong?

N/A

Quality Considerations

I’ve added tests for the menu/sidebar behaviors.

Notes to Reviewer

A few caveats below:

• NTP support is in place, but needs FE work before it’s usable, so I will finalize it once the FE is ready
• strings are being translated for both platforms. Translations are not a blocker for this feature, but I plan to download them once I’m done with the iOS entry points (ETA: tomorrow)
• The entry points are visible, but don’t do anything at the moment. I’ll hook up the landing page when working on this task.

Note

Implements macOS win‑back offer entry points (modal, menu/sidebar badges, preferences updates, NTP banner scaffolding) and exposes shared storage/manager with new state while adding strings, assets, and tests.

• macOS – Win‑back Offer UI:
  • Launch Modal: New prompt presenter/view/view model to show on first eligible launch.
  • Menu Badge: MoreOptionsMenu shows “SAVE 25%” on Subscription when offer available; layout tweaks to MenuItemWithBadge.
  • Preferences:
    • Sidebar badge on Subscription.
    • Purchase/Settings panes updated with offer‑aware CTAs and messaging.
  • New Tab Page: Banner provider + client wiring; promotion view coordinator (awaiting FE consumption).
  • Feature/Debug: Feature flag provider and debug menu (simulate churn/override date); assets added.
  • App Wiring: AppDelegate constructs visibility manager, store, prompt presenter, and promotion coordinator.
• Shared (BrowserServicesKit/Subscription):
  • Make WinbackOfferStoring/WinBackOfferVisibilityManaging public; add didDismissUrgencyMessage state.
  • Inject dateProvider; replace direct Date() usage; minor logic refactors.
• Localization:
  • Add win‑back campaign strings for iOS/macOS (modal, last‑day message, badges, preferences CTAs).
• Tests:
  • Add mocks and unit tests for menu badge visibility, NTP coordinator wiring, and preferences model behavior.
