Is there a browser extension that does meet data privacy concerns adequately (or even well)? Your recommendations welcome.

Wow. Lean Library seems to be sloppily implemented, has a privacy policy that says that big dutch companies that acquire them receive ALL the user data, and the word "collect" doesn't mean what they think it means. The icing on the cake is that their T&C forbid us from reverse engineering their code to see what it really does.

From their "privacy policy":
We may disclose the information we obtain:
If Lean Library is involved in a merger, acquisition or sale of all or a portion of its Please note that you will be notified by either email or a prominent notice on our website of any changes in ownership or uses of this information.
from their T&C
No Reverse Engineering and the like.User nor Licensee may, or may cause or permit any of its employees or any third party to, modify, adapt, translate, reverse engineer, decompile, disassemble, translate or create derivative works based on the Service without the prior written consent of Licensor, which Licensor may withhold in its sole discretion.

Any librarian that pays to hand users over to LL as it presents itself today needs to reflect on their life choices.

Having said that, (and having been involved in browser extension projects) I think LL would be super valuable if done right, with all the i's dotted and t's crossed.

That would mean building independent code review and privacy and data audits of ops into LL's contracts. Remember that giving a company phone-back access to a browser extension gives that company (and anyone with the power or craft to compel that company) to see everything a user does online, credit card numbers, browsing behavior, passwords, EVERYTHING! Libraries need to examine their potential legal liability for their patron's catastrophic security loss if they recommend installation of this product (as presented today.)

If anyone needs technical backup on this, please don't hesitate to contact me.

We are only interested in information or data that can help us deliver the best experience possible in saving you time while and optimizing your academic research. Therefore, The Extension does not store any information for other browsing activity such as activity on non-database webpage urls.

It would be more accurate for them to say that they analyze all sites you visit to determine whether they are academic in nature, or something. But that would be a red flag."
