Handling

Does the service allow third-party access to private personal data? Yes, all parties specified (including non-critical service providers such as advertisers)

3/10

Decided Aug. 28, 2019 (revision history). This question accounts for 12% of the final score.

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).

"Webpage data for Pocket Recommendations: We recommend content to you based on your browsing history. The process of deciding which stories you should see happens locally in your copy of Firefox and neither Mozilla nor Pocket receives a copy of your browsing history. We do receive data about the recommendations you see and click. Learn more."

Note

While Firefox suggests content based on browsing history and other factors, it happens locally on the client's side and is not used to generate profit.

When the law requires it. We follow the law whenever we receive requests about you from a government or related to a lawsuit. We'll notify you when we're asked to hand over your personal information in this way unless we're legally prohibited from doing so. When we receive requests like this, we'll only release your personal information if we have a good faith belief that the law requires us to do so. Nothing in this policy is intended to limit any legal defenses or objections that you may have to a third party's request to disclose your information.

Collection

Is it clear why the service collects the personal data that it does? Yes

10/10

Decided Aug. 27, 2019 (revision history). This question accounts for 12% of the final score.

This question deals with transparency. Even if the service uses data for reasons that aren't ideal for privacy, provided they list all of those uses, the service can still receive full credit for this question. However, if they are not explicit about their uses (by employing language like "such as"), a lower score is assigned.
