Replace AppsFlyer: RAM-only events

Q: What's the actual flush cadence?

30 seconds by default, plus a flush on `applicationDidEnterBackground` (iOS) / `onPause` (Android). Most events reach the network within seconds of being fired.

▸Example AppsFlyer call (the "before")

swift Respectlytics

import AppsFlyerLib

// ATT prompt path — required before AppsFlyer reads IDFA:
ATTrackingManager.requestTrackingAuthorization { _ in
    AppsFlyerLib.shared().start()
    AppsFlyerLib.shared().logEvent("af_purchase", withValues: [
        AFEventParamRevenue: price,
        AFEventParamCurrency: "USD",
        AFEventParamContentId: sku,
    ])
}

Most analytics SDKs back the unsent event queue with SQLite or UserDefaults / SharedPreferences — so a phone that's been confiscated, jailbroken, or restored from backup still contains analytics state. Respectlytics's queue is RAM-only, flushed on a 30-second timer; unsent events on force-quit are lost by design, in exchange for zero on-device forensic surface.

☑Remove AppsFlyer cleanly

1
Remove the AppsFlyer SDK from your build (AppsFlyerFramework / af-android-sdk / react-native-appsflyer / appsflyer_sdk)
2
Remove AppsFlyerLib.shared().start() and logEvent(...) call sites
3
Re-check your Info.plist for NSUserTrackingUsageDescription — if no other SDK needs ATT, remove it (Apple flags apps that ship the key without code that calls ATTrackingManager)
4
Re-check your Android merged manifest for com.google.android.gms.permission.AD_ID and remove the corresponding <uses-permission> if no other SDK contributes it
5
Plan how you'll attribute installs without AppsFlyer — Apple SKAdNetwork + Google Play Install Referrer (both first-party, no SDK needed) cover most cases

⇋AppsFlyer vs Respectlytics — ram-only event queue

	AppsFlyer	Respectlytics
Event queue persistence	SQLite / UserDefaults / SharedPreferences	In-memory ring buffer
Disk usage for analytics	0.5–10 MB typical	0 bytes
Forensic data on jailbroken / rooted devices	Persistent identifiers + queued events	None
Survives force-quit before flush	Yes	No (events lost — by design)

❓Frequently asked questions

Doesn't this reduce data quality?

Marginally — typical force-quit-before-flush event loss is 0.5–2% depending on platform. For aggregate metrics (funnel rates, feature adoption, release deltas) this is invisible. For per-event reconciliation it would be a problem, but per-event reconciliation isn't a use case Respectlytics supports.

What's the actual flush cadence?

30 seconds by default, plus a flush on applicationDidEnterBackground (iOS) / onPause (Android). Most events reach the network within seconds of being fired.

Is this safe for crash analytics?

Crash analytics is a separate concern — use Sentry, Crashlytics, or Bugsnag (with their own crash-aware queues). Respectlytics is product analytics; crash data has different recoverability requirements and lives in different tools.

Why is this a privacy feature?

Devices that are jailbroken, rooted, restored from backup, or forensically imaged routinely surface analytics artifacts — distinct_ids, queued events, user properties — that survive uninstall in some cases. RAM-only storage moves the dump-recovery surface to zero.
