## Android reference
Android uses **shared pixels** for both the reinstaller promo and the day-7 promo, with **no `origin` pixel parameter** — origin is only embedded in the subscription purchase URL (`https://duckduckgo.com/pro?origin=…`) for downstream funnel attribution:
Android has **separate pixels and origins per audience**, managed via a `SubscriptionPromoFlow` enum in `Cta.kt` (current main branch):
| Event | Android pixel string | `origin` in URL |
|---|---|---|
| Shown (both audiences) | `m_odc_s` | `funnel_browsermodal_android` (unified; was `funnel_skippedonboarding_android` / `funnel_newusermodal_android` before unification) |
| CTA tapped (both audiences) | `m_odc_ok` | same as above |
| Dismissed (both audiences) | `m_onboarding_dax_cta_dismiss` | same as above |
| Flow | Audience | Origin (in URL) | Shown pixel | Subscribe pixel |
|---|---|---|---|---|
| `SKIPPED_ONBOARDING` | Reinstaller / skipped onboarding | `funnel_modal_android__skippedonboardingupsell` | `m_subscription_promo_modal_skipped_onboarding_shown` | `m_subscription_promo_modal_skipped_onboarding_subscribe_clicked` |
| `NUDGE` | Day-7 existing users | `funnel_modal_android__subscriptionnudge` | `m_subscription_promo_modal_nudge_shown` | `m_subscription_promo_modal_nudge_subscribe_clicked` |
The two audiences are **indistinguishable at the pixel level** on Android — analysis relies on the origin flowing to downstream purchase pixels. Source: [Android PR #8369](https://github.com/duckduckgo/Android/pull/8369), `BrowserTabViewModel.kt` + `CtaViewModel.kt`.
Both flows also fire legacy shared pixels (`m_odc_s` shown, `m_odc_ok` CTA tap, `m_onboarding_dax_cta_dismiss` dismiss) inherited from the base `Cta` interface — there is no dismiss-specific per-audience pixel on Android.
Android pixel definition / privacy triage tasks cover Phase 1 paywall instrumentation only (`m_subscription_paywall_not_seen_*`) — the promo modal itself got no separate pixel definition or privacy triage:
The iOS origin task's suggested name `funnel_modal_ios__subscriptionnudge` follows the same format as Android's `funnel_modal_android__subscriptionnudge`. Source: `Cta.kt`, `CtaViewModel.kt` on Android main.

## Option A — Recommended: Reuse existing pixels (mirrors Android approach)
## Proposed pixels (mirrors Android)
Reuse `m_privacy-pro_skipped_onboarding_promotion_[impression|tap|dismiss]` for the day-7 audience. Audience attribution relies on the origin URL parameter (`funnel_modal_ios__subscriptionnudge`) flowing to downstream purchase pixels — identical to Android's approach.
**No new pixels required. No privacy triage required for new pixels.**
| Pixel | Trigger |
|---|---|
| `m_privacy-pro_skipped_onboarding_promotion_impression` | Day-7 half-sheet shown |
| `m_privacy-pro_skipped_onboarding_promotion_tap` | User taps CTA |
| `m_privacy-pro_skipped_onboarding_promotion_dismiss` | User dismisses without tapping CTA |
**Trade-off:** Cross-audience analysis (reinstallers vs day-7 existing users) is not directly available from pixels alone; it requires joining on origin via downstream `m_privacy-pro_offer_screen_impression` / `m_subscribe` pixels.

## Option B — Alternative: Separate pixels per audience
Define three new pixels exclusively for the day-7 audience. Provides direct per-audience split in pixel dashboards without filtering by origin. Requires a new privacy triage.

## Notes and status
- Option A pixels are already defined in `subscription.json5` as `m_privacy-pro_skipped_onboarding_promotion_[impression|tap|dismiss]`; reusing them for this audience requires no code changes to pixel definitions.
- If Option B is chosen, new definitions must be added to `subscription.json5` and a privacy triage opened.
- Privacy triage (for Option B): [Insert Privacy Triage link]
- The iOS origin value needs to be formally submitted and approved via the [Origin Proposal form](https://form.asana.com/?k=Wy3aY17vglr2bihpUHoyBA&d=137249556945).
