Protection levels.

Locally stored data (Data-at-Rest, DAR).

Locally stored data groups include Media Information, Analytics ‘n’ Ads Information, Documents Information, Storage Information, Credentials Information.
The average DAR value is 6.12 points (7.00 points of system protection and 5.23 points of own protection). It is higher than a typical value (3.5 points, where’s 7 points of system protection and 0 points of own protection).

Items’ GROUP #1 with average value 6.50 points (7 points of system protection, 6 points of own protection) means data protection levels have following definitions. Frankly talking, protection and privacy issues are still possible but might involve interaction with an app code where system protection level means – root/jailbreak is required but not possible without wiping device data, and own protection level means – data is not available in backups.

– Screen Snapshots (‘Media Information’ Group) – Screenshots of your device screen running certain apps; common as an iOS app multitasking feature (app swipes) or browser tab swipes. This data item related to mentioned group meant to be any data like photo, image, video, audio,

– Document Details (‘Documents Information’ Group) – Common info about documents synchronized or stored locally (properties like size, date and time, etc.). This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format,

– Sync Documents (‘Documents Information’ Group) – Documents synchronized or locally stored on your device as is or converted into another file formats (like.pdf or set of separated jpg file per each .pdf file. This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format,

– Document List (‘Documents Information’ Group) – The list of documents stored local or synchronized over the Internet. This data item related to mentioned group meant to be any documents stored locally, uploaded, downloaded, synchronized in any file format,

– Sync Documents (‘Storage Information’ Group) – Documents synchronized or locally stored on your device as is or converted into another file formats (like.pdf or set of separated jpg file per each .pdf file. This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on,

– Document Details (‘Storage Information’ Group) – Common info about documents synchronized or stored locally (properties like size, date and time, etc.). This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on,

– Document List (‘Storage Information’ Group) – The list of documents stored local or synchronized over the Internet. This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on,

– Account Data (‘Storage Information’ Group) – Basic info about account like name, a list of sub-account (e.g. financial or other) and some linked data like a phone number. This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on,

– Credentials (IDs) (‘Storage Information’ Group) – Only account IDs like app or 3rd party user IDs including emails, phone number, usernames, etc. (depends on apps). This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on,

– Credentials (Tokens) (‘Storage Information’ Group) – Different tokens used to get access to your account, except for passwords but including app or 3rd party tokens, secret keys, etc. (usually give full access to your account). This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on

Items’ GROUP #2 with average value 3.50 points (7 points of system protection, 0 points of own protection) means data protection levels have following definitions. Frankly talking, extra data found that shouldn’t be accessed where system protection level means – root/jailbreak is required but not possible without wiping device data, and own protection level means – stored as is.

– Device Data (‘Analytics ‘n’ Ads Information’ Group) – Device ID, Device Name, Device OS Name and Version, and jailbroken/root status. This data item related to mentioned group meant to be any info related to analytics services like Flurry, Google Analytics, etc. or advertisements,

Items’ GROUP #1 with average value 4.50 points (5 points of system protection, 4 points of own protection) means data protection levels have following definitions. Frankly talking, data available if it’s allowed only and may require user action where system protection level means – some techniques are available to developers to keep connection bypassing system settings, like proxy settings, etc., and own protection level means – bypassed by fake/stolen root certificates.

– Credentials (IDs) (‘Storage Information’ Group) – Only account IDs like app or 3rd party user IDs including emails, phone number, usernames, etc. (depends on apps). This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on,

This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on

Items’ GROUP #2 with average value 5.50 points (5 points of system protection, 6 points of own protection) means data protection levels have following definitions. Frankly talking, data is not available all the time or partially accessed where system protection level means – some techniques are available to developers to keep connection bypassing system settings, like proxy settings, etc., and own protection level means – SSL pinning (can be patched).

– Document Details (‘Storage Information’ Group) – Common info about documents synchronized or stored locally (properties like size, date and time, etc.). This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on,

– Sync Documents (‘Storage Information’ Group) – Documents synchronized or locally stored on your device as is or converted into another file formats (like.pdf or set of separated jpg file per each .pdf file. This data item related to mentioned group meant to be any information referred to storage like credentials, settings, documents and so on,
