How links work
What happens when someone taps a link, on every platform.
Every link lives on your link domain: https://go.yourbrand.com/<code>. When someone taps it, Dropplink
records the tap and sends them on in a few milliseconds. The redirect never waits for the tap to be saved.
Where a tap goes#
Android fallbacks skip the Play Store
An Android fallback replaces the Play Store redirect, so it carries no click_id, and installs from it can't be attributed. Use it only for
installs outside Google Play.
What's recorded for each tap#
Each tap gets a unique click ID and is stored with its channel (how channels are detected), platform, device and OS version, country, and whether it was a bot. IP addresses are hashed with a salt that rotates daily and are never stored as they are.
Why the Play Store referrer matters#
On Android, the Play Store hands the referrer from the store URL to your app after it's installed. Your
app reads the click_id from it and sends it to Dropplink, which matches the install to that exact tap.
This is deterministic: no guessing. iOS has no equivalent, so iOS installs will be matched with device
signals within your attribution window.
