Data Locker
Main features
- Apps: supports multiple apps
- Simplicity: Data is deposited into an Amazon S3 bucket and manage the storage requirements
- Reliability: data is stored in AWS which ensures data persistence
- Flexibility: choose what data you want to include in the reports
- Granularity: data is segmented into report types, days and hours
- Accessibility: pull data when required
Data segmentation
Data in Data Locker is segmented into folders as follows:
- Report types
- Days
- Hours
This means that for each report type, on a given day, the data is separated into separate folders by arrival hour and not by the data event time. For example, ../t=installs/dt=2019-01-17/ contains 25 folders. There are 24 folders for each hour of the day, from 0 to 23 and an additional folder for data that arrives late.
- To understand the folder structure and how hourly segmentation works, see folder structure and format.
- For an explanation about the Late folder.
Data freshness: Data is separated into arrival hour folders. That is the hour that the event was processed in AppsFlyer. The Data Locker folder is written within six hours of processing.

Protect 360 is an AppsFlyer premium solution.
- (optional) In-app events (default=All) Select the in-app events to include .
- Click Apply.
- (optional) Fields (default=All): Select the fields to include in the reports. Note: We add fields from time to time.
- (optional) Recipients Email list of people to notify when reports are ready. To add more than one recipient, sperate the emails using a comma, for example, user1@example.com, user2@example.com.
- Click Create Bucket.
Bucket credentials
Once the configuration is saved, a dedicated AWS bucket is created. The bucket details appear at the top right-hand corner of the screen. They include the Bucket Name, Home Folder, and credentials for accessing data.
The bucket is only accessible using customer credentials (for security reasons). In addition, all access to the bucket is audited.
Data availability
- Data is updated hourly after a six-hour delay
- Each file includes the apps selected
- Retention: Files and folders are available for 30 days. After 30 days the data is deleted
Folder structure and format
- Folder structure is: af-ext-reports/<Home Folder>/data-locker-hourly/t=<event-type>/dt=<date YYYY-MM-dd>/h=<Hour h>
- The Home Folder is the Home Folder that appears in the Credentials window (see the setup instruction in the prior section)
- For example, for the date 2016-08-12 the relevant report appears under:
s3://af-ext-reports/12345678911-acc-1abc234/data-locker-hourly/t=installs/dt=2016-08-12/ - The folder dt=yyyy-mm-dd is split into 25 hourly folders. These folders represent the arrival hour of the event, not the event hour of the event itself. The folders are named h=0, h=1, h=2, and so on, up to h=23, and h=late. For example, the folder h=0 contains the events that arrive between 00:00 and 01:00, similarly, the folder h=20 contains the events that arrive between 20:00 and 21:00.
-
In each folder, data may be split into multiple files to avoid large files. Depending on the type of data exported, folders can contain up to 1000 files. This number may change without notice. Files are named part-00000, part-00001, part-00002, and so on.
- In each folder, the last file to be written is always an empty file named _SUCCESS. This file is a flag to indicates that no further data will be written to the folder. As such, do not read data in a folder before verifying that the _SUCCESS file exists. Note: The _SUCCESS flag is also written in cases where there is no data to be written to the folder.
Late folder
The Late folder contains events of the preceding day that arrived after 0000 UTC +0 (midnight) midnight and up to 02:00 UTC +0. It also contains the _SUCCESS flag as described in the previous section. Automated processes should look for data in the late folder as is done for all the other folders of the day.
Example
An event is received by AppsFlyer on January 21st at 1:15 AM. The event has a timestamp of January 20th at 18:45. Because this event arrived late, it will be placed in the late folder inside the /dt=2019-20-01/ h=late folder.
File structure and format
- Data Locker files are based on Raw Data Reports V5 (see: Raw Data Reports V5).
- The actual data file is in CSV format but it has no file extension.
- The report files are zipped in .gz format (to make the download process efficient).
- Each file has a header row.
- Values that have a coma in them are contained between double quotes `"`, for example
`"iPhone6,1"`.
Retrieving data from Data Locker
AppsFlyer creates an AWS principle (ARN in Amazon terms) and generates credentials for that principle. A policy is then set allowing the principle to browse and retrieve files from the bucket.
You can access the bucket using AWS command-line tools and most FTP clients. To use these tools, retrieve the credentials, AWS Access Key and AWS Secret, from the Credentials section.
Data can be accessed using the following tools, amongst others:
- CLI: AWS CLI
- Windows: There are a number of tools available like Cyber Duck or Amazon S3 Browser. DragonDisk is not fully supported.

Using reports as data sources
You can use the data from the reports and add it to your own databases. To extract the data and add it to your databases you need to know the report format. Data Locker reports are based on Raw Data Reports. However, the final report format depends on the fields that you choose to include.
Report format
The fields available in Data Locker are listed in the data field dictionary V5.0
Tip
The reports contain data that you can use for campaign optimization and retargeting.
Examples
- Clicks report - the clicks report contains the IDFA or Google Advertising ID. You can use these IDs to retarget users that engage with your ads but fail to install the app.
- Impression report - Like the clicks report, the impression report also contains the IDFA or Google Advertising ID. You can use the impression report to optimize campaigns according to impressions that don't lead to clicks. You can also retarget these users with different ads and in different campaigns.
- Retargeting and Re-attribution report - these reports also contain the IDFA or Google Advertising ID. You can use the IDFA or Google Advertising ID to highlight those users that you manage to retarget. Knowing what users you manage to retarget can help you optimize retargeting campaigns.
Note: To benefit from IDFA or Google Advertising ID as explained above, make sure they are included in all your attribution links.
Hourly reports
Data Locker separates data into hourly folders. The hourly folder represents the processing hour and not the hour that the event occurred. The data is written to Data Locker within six hours of processing.
Example
AppsFlyer receives data for activity between 14:00 and 15:00 on January 17, 2019. At some time after 15:00 AppsFlyer begins processing the data. Due to processing, the data is not written to Data Locker immediately. Thus the data in folder /t=installs/dt=2019-17-01/h=14 is not available on January 17th, 2019 at 15:00 but rather six hours later.
Creating hourly folders
In cases where there is no data for a specific hour, Data Locker creates a folder for that hour. This is to indicate to you that there was no data in that hour. The folder will contain a `_SUCCESS` file which indicates that AppsFlyer has completed writing to this folder. When designing automated processes this should be taken into account, meaning design your data retrieval processes so that they can handle empty hourly folders.
Clicks and impressions of SRNs vs. non-SRNs
- Non-SRNs use AppsFlyer attribution links for clicks and impressions. This provides AppsFlyer with the complete data set of the engagement which is then written to Data Locker.
- SRNs (Self-reporting networks) don't use AppsFlyer attribution links. As a result, only after an app open does the SRN share click and impression information, which is then written to Data Locker. To clarify, AppsFlyer is not aware of clicks and impressions which do not result in an app open. Note: Aggregate data reports include all clicks and impressions even if no app open took place.
Amazon clicks and impressions
Amazon clicks and impressions are not supported. They do not appear in the reports that are stored in Data Locker.
Timezone and currency
App-specific timezone and currency settings don't have an effect on data in Data Locker.
TImezone: Data Locker reports use the UTC timezone
Currency: The field event_revenue_usd is in USD.

Troubleshooting
- Symptom: Unable to retrieve data using AWS CLI
- Error message: An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied
- Cause: The AWS credentials being used not the correct credentials for the AppsFlyer bucket. This can be caused by having multiple or invalid credentials on your machine.
- Solution:
- Use a different method, like Cyber Duck to access the bucket, meaning not the CLI. Do this to verify that the credentials you are using are working. If you are able to connect using Cyber Duck, this indicates an issue with the credentials cache.
- Refresh the AWS credentials cache.
