At a glance: Data freshness is the period of time between event occurrence and data availability in the platform.
Time zones
Data freshness and support for app-specific time zones
Data freshness
The AppsFlyer platform utilizes different types of data freshness, such as daily and real-time. They are used to present and make data available. Each has its own data freshness rate.
Example: Data freshness rates on the Events dashboard:
- Metric KPI: real-time
- Average KPI: daily
For daily reports, the last update time appears in the top right-hand corner of the page.
Time zones
In the AppsFlyer platform, a day starts at 00:01 and ends at 24:00. The default time zone is UTC (GMT). You can modify the default by setting an app-specific time zone.
Date and time-zone principles
UTC time is constant and doesn't have summer/winter times.
Hemispheres
- Eastern: Time zones designated as UTC+ are those located to the east of UTC.
- Western: Time zones designated as UTC - are those located to the west of UTC.
App-specific time zone
You can set an app-specific time zone. This means that the data is grouped into days using local time instead of UTC.
Example:
Beijing: If the app-specific time zone is set to Beijing (UTC +8), then the day starts at 16:01 UTC and ends at 16:00 UTC the following day.
Los Angeles: If the app-specific time zone is set to Los Angeles (UTC -8), then the day starts at 08:01 UTC and ends at 08:00 UTC the following day.
Time-zone guidelines
- Align your app-specific time zone with the time zone you set for other attribution service providers such as Google and Facebook.
- If you have more than one app, the best practice is to set all apps to the same time zone. To view an app's time zone setting, go to Configuration > App Settings.
- Most reports and data extraction tools support app-specific time zones. This includes multi-app reports if all apps are set to the same app-specific time zone.
Daily processing
Some reports and pull-down lists are processed once a day, this is referred to as daily freshness or daily processing. These are the principles of daily processing:
- Data belonging to a specific day, for example, Monday, is collected in a bucket. The day begins at 00:01 and ends at 24:00 using the app-specific time.
- Data received up to two hours after midnight is included in the day's bucket. Data received up to 02:00 on Tuesday is included in Monday's bucket.
- At 02:00 local time, the bucket is closed, and no more data can be added to it.
- Data received after 0200 is placed in the next available bucket, irrespective of the event date.
- Daily processing of the closed bucket begins two hours after midnight UTC irrespective of the app-specific time zone. For the sake of simplicity, we state that processing starts at midnight UTC. This means that, depending on the local time zone, the bucket needs to wait until midnight UTC before processing begins.
Eastern hemisphere and UTC time zone:
- Up to 11 hours can pass from the time the day ends (local time) until processing begins. For example:
- Beijing (UTC+8): Need to wait eight hours before processing begins
- Berlin (UTC +1): Need to wait one hour before processing begins
- UTC: No waiting time.
- Depending on the report type, the data is available 8-20 hours after the start of the processing. For example, Beijing data is available from 16:00 local time. Berlin data is available from 09:00.
Western hemisphere:
- Up to 23 hours can pass from the time the day ends until processing begins. For example:
- Los Angeles (UTC -8): Need to wait 16 hours before processing begins
- New York (UTC -5): Need to wait 19 hours before processing begins
- Depending on the report type the processed data is available 8-20 hours after the start of the processing begins. For example, Los Angeles data is available from 00:01 local time two days after the event. New York data is available from 03:01 local time two days after the event.
- Example:
- Events take place on Monday Los Angeles time (UTC -8), the daily processing begins at midnight UTC Tuesday. This is Los Angeles Tuesday 16:01.
- Eight hours later, on Wednesday 00:01 Los Angeles time, the data processing is complete. In practical terms, data from Monday is available to advertisers in Los Angeles when they begin work on Wednesday morning.
Data freshness types
| Rate | Availability | Description |
|---|---|---|
|
Continuous (AKA real-time) |
Several minutes after the occurrence and subsequent processing of the event | Data processing is continuous or in near real-time. This term distinguishes it from batch processing which takes place, for example, daily or hourly. In most cases, continuous data is updated within several minutes of the occurrence of an event. Expect some variation in lag times from event occurrence until it reflects in reports and dashboards. |
|
Real-time report |
Few minutes after requesting a report |
The data freshness is in real-time until the request is made |
|
Daily |
UTC zone: 8 hours after midnight UTC on the day of the event
Eastern hemisphere: 9-20 hours after midnight UTC on the day of the event Western hemisphere: 21-32 hours after midnight UTC on the day of the event |
|
|
EOD |
Daily at the end of the day app-specific timezone | At the end of the calendar day. Meaning 00:01 of the following day. Example: Data recorded on Monday is available starting from Tuesday at 00:01 irrespective of the app-specific timezone. |
|
Intraday (during the day) |
Every 4 hours on average |
|
|
Ad revenue |
Data is available ~40 hours after the end of day UTC on which the ad displays. |
Example: An ad displays on Day 0. The revenue data is pulled from the ad networks on Day 1 at 1400 UTC and processing begins Day 2 at 00:01 UTC. The data is available in the Dashboard on Day 2 from ~16:00 UTC. Data is reported under Day 0.
|
|
PBA Daily |
Data is available 8-10 hours after the end of the day UTC. |
|
|
SKAdNetwork |
Updated data displays approx. 68 hours after install. Range 32-104 hours. |
Postbacks received on a given day are processed at the end of the day UTC. Data is available by 08:00 UTC of the following day. Meaning iOS postbacks received Monday are available in reports and dashboards on Tuesday morning. Similarly, postbacks to partners are sent on Tuesday morning. The install date in reports and dashboards is derived from the postback arrival time as follows:

Data Locker Daily |
Data is available 8–10 hours after the end of the day UTC |
