# Pixel Definition: iOS Day-7 Subscription Promo Half-Sheet

---

## Background

- **Project:** [iOS: Show subscription half-sheet promo to new installers who don't see it during onboarding](https://app.asana.com/1/137249556945/project/1202406491309510/task/1214798984829406)
- **Android counterpart:** [Grow active subscriptions by increasing paywall impressions with a day 7 promo half-sheet](https://app.asana.com/1/137249556945/project/72649045549333/task/1210994036696114) — the iOS implementation follows the same approach and target audience as Android
- **Origin request:** [Request origin for iOS subscription promo half-sheet entry point](https://app.asana.com/1/137249556945/task/1214800683792174) — origin value `funnel_modal_ios__subscriptionnudge` (Android equivalent: `funnel_modal_android__subscriptionnudge`)
- We are adding a new half-sheet modal for existing users (7+ days since install) who have never seen any subscription offer. The modal reuses the pre-existing `SubscriptionPromoLaunchView` UI.
- Existing subscription promo pixels already cover related audiences:
  - `m_privacy-pro_onboarding_promotion_impression/tap/dismiss` — users who see the promo during onboarding
  - `m_privacy-pro_skipped_onboarding_promotion_impression/tap/dismiss` — reinstallers who skipped onboarding (7+ days)

## Objective

- Define three new pixels (impression, tap, dismiss) for the day-7 existing-user promo half-sheet.
- Mirror the parameter shape of the existing `m_privacy-pro_skipped_onboarding_promotion_*` pixels to allow cross-audience comparison.
- These are permanent pixels (no expiry) — the feature is not an experiment.
- The origin value `funnel_modal_ios__subscriptionnudge` flows downstream automatically to `m_privacy-pro_offer_screen_impression` and `m_subscribe` without additional work.

## Testing the feature

- Feature is implemented in: `iOS/DuckDuckGo/SubscriptionPromo/SubscriptionPromoExistingUserCoordinator.swift`
- Test paths:
  - Install app, complete or skip onboarding
  - Wait 1 minute (1-min override active — revert to 7 days before shipping)
  - Background and re-foreground app → promo half-sheet should appear
  - Verify `m_privacy-pro_existing_user_promotion_impression` fires on display
  - Tap CTA → verify `m_privacy-pro_existing_user_promotion_tap` fires and subscription flow opens with origin `funnel_modal_ios__subscriptionnudge`
  - Re-install and dismiss instead → verify `m_privacy-pro_existing_user_promotion_dismiss` fires

## Final pixels (for triage)

### `m_privacy-pro_existing_user_promotion_impression`

- **Trigger:** The day-7 promo half-sheet is shown to an existing user (7+ days since install) who has never seen any subscription offer.
- **Frequency:** Once per install (guarded by `daxDialogsSettings.subscriptionPromotionDialogShown`).
- **Fired from:** `SubscriptionPromoExistingUserCoordinator.markLaunchPromptPresented()`
- **Parameters:**
  - `appVersion` — app version (added by default)
  - `ru` — `true` / `false` — whether the user is a returning user (reinstall)
  - `free_trial` — `true` / `false` — whether the user is eligible for a free trial at time of display
- **Suffixes:** `_ios`, `_phone` / `_tablet`

### `m_privacy-pro_existing_user_promotion_tap`

- **Trigger:** User taps the CTA button ("Try It Free" or "Learn More") on the promo modal.
- **Frequency:** Standard (can fire once per impression, since the modal is shown at most once).
- **Fired from:** `SubscriptionPromoExistingUserCoordinator.handleCTAAction()`
- **Parameters:** same as impression — `appVersion`, `ru`, `free_trial`
- **Suffixes:** `_ios`, `_phone` / `_tablet`

### `m_privacy-pro_existing_user_promotion_dismiss`

- **Trigger:** User dismisses the promo modal (taps X or swipes down) without tapping the CTA.
- **Frequency:** Standard.
- **Fired from:** `SubscriptionPromoExistingUserCoordinator.handleDismissAction()` and `UIAdaptivePresentationControllerDelegate` (swipe-to-dismiss)
- **Parameters:** same as impression — `appVersion`, `ru`, `free_trial`
- **Suffixes:** `_ios`, `_phone` / `_tablet`

---

## Behavior rules

- Impression and tap/dismiss are mutually exclusive per install — the modal is shown at most once.
- `ru` and `free_trial` are evaluated at time of display, same as in the skipped-onboarding promo.
- The dismiss pixel fires on both explicit close (X button) and swipe-to-dismiss; neither path fires the tap pixel.
- If the user taps CTA, tap fires but dismiss does not.

## Notes and status

- Pixel definitions are committed to `iOS/PixelDefinitions/pixels/definitions/subscription.json5`.
- These pixels are structurally identical to `m_privacy-pro_skipped_onboarding_promotion_*` (same parameters, same suffixes) — no new parameter types are introduced.
- Android equivalent pixels: the Android implementation fires analogous `m_privacy-pro_skipped_onboarding_promotion_*` pixels (Android reused the existing reinstaller promo pixel names for the day-7 promo since it shipped first).
- Origin `funnel_modal_ios__subscriptionnudge` needs formal approval via the [Origin Proposal form](https://form.asana.com/?k=Wy3aY17vglr2bihpUHoyBA&d=137249556945) — tracked in the origin request subtask above.
- Privacy triage is required for the new pixels — see `ios-subscription-day7-promo-privacy-triage.md`.
