Reviews for Keepa.com - Amazon Price Tracker
Keepa.com - Amazon Price Tracker by Keepa.com
Review by Giampaolo Ferradini
Rated 5 out of 5
by Giampaolo Ferradini, 7 years agoVery useful extension. I am basically not purchasing anything without having had a look at Keepa's price history. You can also create custom alerts and decide to include special offers like Amazon's warehouse deals, etc. Very happy.

- Rated 1 out of 5by Firefox user 19139831, an hour agoThe item tracking and alerts were changed to subscription, not great but I understand, at least it was still working directly on the Amazon website. Then got an alert from Firefox about the extension asking for concerning new permissions.
I guess is time to say goodbye and find new alternatives. Developer response

Mozilla now requires every add-on to declare data categories from a fixed list, and Firefox displays them on update.
What Keepa does: on an Amazon product page it sends that product's ASIN to keepa.com to draw the price chart. It is not logged and not retained. Nothing is stored unless you choose to track a product. The "personally identifying information" line refers to your Keepa session token - a login credential for your own account, not your name or email. We think that's the wrong label and have asked Mozilla to change it to "authentication information".

The extension runs only on Amazon product pages.- While the extremely worrying "new" permissions may just be an artifact of Mozilla new categorizing for disclosure, the module still seems to go behind the user's back using his browser to execute unrelated requests for it.
Whether this is abnormal in relation to Mozilla or Amazon guidelines, and GDPR, and the requirements for the developers, I cannot properly evaluate, but I'm still concerned about.
I would encourage the developers and users to eg read Wladimir Palant's blog post titled "Data exfiltration in Keepa Price Tracker".Developer response
posted 2 hours agoThank you for sharing your feedback. We would like to clarify a few points regarding the blog post and explain the updates we have made to the add-on.
The post by Wladimir Palant contained several sensationalized claims and key factual inaccuracies regarding how our add-on handles data. While we appreciate community oversight, many of the assertions made did not accurately reflect our module’s design or intent.
To eliminate any ambiguity and address user concerns directly, our latest update completely removes all background data collection capabilities. The add-on now functions as a minimalist wrapper designed solely to embed the price history chart, ensuring maximum privacy and transparency while maintaining core functionality.
Please feel free to reach out to info@keepa.com if you have further questions. - Do NOT post BAD reviews if you are not aware of this information (from Keepa support):

Do not blame Keepa for things required by Mozilla.
This kind of "issue" also happens On Google Play.
I'll keep using this addon! Developer response

posted a day agoAn der Art und Weise, wie Keepa mit Daten umgeht, hat sich durch dieses Update nichts geändert.
Mozilla verlangt jetzt von jedem Add-on, Datenkategorien aus einer vorgegebenen Liste anzugeben, und Firefox zeigt diese bei einem Update an.
Was Keepa macht: Auf einer Amazon-Produktseite sendet es die ASIN dieses Produkts an keepa.com, um den Preisverlaufsgraphen zu laden. Diese Angabe wird weder protokolliert noch gespeichert. Es wird nichts gespeichert, es sei denn, Sie entscheiden sich dafür, ein Produkt zu verfolgen. Zeile für „personenbezogene Daten“ bezieht sich auf Ihren Keepa-Sitzungs-Token – ein Anmeldedatum für Ihr eigenes Konto, nicht auf Ihren Namen oder Ihre E-Mail-Adresse. Wir halten das für die falsche Bezeichnung und haben Mozilla gebeten, dies in „Authentifizierungsinformationen“ zu ändern.
Die Erweiterung läuft ausschließlich auf Amazon-Produktseiten.- Rated 1 out of 5by Firefox user 15488487, a day ago
- Rated 1 out of 5by Dark Thoughts, a day agoAfter 2 years of absence, the clown developers suddenly ask for invasive & personal tracking permissions with a sudden "bug fixes, code optimizations" update.

Original: Uninstalling until the recent changes requiring lots of personal data collection is rolled back. There is no need for this info and hasn't been needed for years. Enshitification.Developer response
