Handling

Does the policy allow personally-targeted or behavioral marketing? No

10/10

Does the service allow you to permanently delete your personal data? N/A

5/5

Does the service allow third-party access to private personal data? No

10/10

This may come in the form of outright data sharing or by using local third-party analytics software (such as Google Analytics, which collects a plethora of user information).

Note that whether the policy allows sharing aggregated user data does not affect this question.

If the personal data is encrypted when it passes through the third-party, it does not count as third-party access (as the data is inaccessible to that party).

If personal data has been made public by, for example, posting it to a blog, it does not count as private personal information (and is therefore not considered by this question).

IP addresses: We receive IP addresses of downloaders and uploaders as part of our standard server logs. These are retained for 90 days, and for that period, may be connected to activity of a file’s download URL. Although we develop our services in ways that minimize identification, you should know that it may be possible to correlate the IP address of a Send user to the IP address of other Mozilla services with accounts; and if there is a match, this could identify the account email address.
Firefox Account: This is required for authentication only if you wish to upload larger file sizes. Your Firefox Account record will retain aggregate data on your usage of Send: for example, if you created a Firefox Account in connection with Send, number of files sent and approximate file sizes, and how many times you’ve used the service.

Does the service allow the user to control whether personal data is collected or used for non-critical purposes? N/A (no data used for non-critical purposes)

10/10

Does the policy list the personal data it collects? Yes, exhaustively

10/10

Score

The policy does not claim to not collect personal data, but it also doesn't provide any meaningful insight into the types of personal data it collects.

Only summarily

The policy uses overly vague language to provide a summary of the types of collected personal data.

30%

Yes, generally

All general categories of collected personal data are listed, though not all types of personal data are explicitly mentioned (for example, the list might use a phrase like 'such as' when listing types of personal data).

Personal data: The following is necessary to provide the service:
IP addresses: We receive IP addresses of downloaders and uploaders as part of our standard server logs. These are retained for 90 days, and for that period, may be connected to activity of a file’s download URL. Although we develop our services in ways that minimize identification, you should know that it may be possible to correlate the IP address of a Send user to the IP address of other Mozilla services with accounts; and if there is a match, this could identify the account email address.
Firefox Account: This is required for authentication only if you wish to upload larger file sizes. Your Firefox Account record will retain aggregate data on your usage of Send: for example, if you created a Firefox Account in connection with Send, number of files sent and approximate file sizes, and how many times you’ve used the service.
Non-personal data: We receive the following to improve our service and performance:
Interaction data: This includes information such as number of people sending and receiving files, number of files uploaded and approximate file sizes, percentage of file downloaders who become uploaders, how people engage with the website (time spent, clicks, referrer information, site exit path, use of passwords).
Technical data: This includes information such as operating system, browser, language preference, country, timestamps, duration for file transfer, reasons for errors, reasons for file expiration.
