Keepa.com - Amazon Price Tracker by Keepa.com
Review by Firefox user 15567644
Rated 4 out of 5
by Firefox user 15567644, 7 years agoA good app with tons of cool features. As far as I can see it works fine, the most useful feature probably being the price graph under every product.
However Keepa is sometimes extremely slow when it comes to notifying you of a price change. Like hours too slow.
First of all it seems to only be able to refresh your tracked product once an hour.
And then when it does refresh, it can delay sending you the notification even further for some reason.
I tried using it to track an extremely in-demand product, which flew off the shelf almost immediately after it got there. Keepa sent me a heads up on messenger. 2 hours after the thing sold out.
This method of operation/occasional hiccups are probably fine when trying for regular amazon deals that normally last a few hours(which is what I will continue to use it for), but for tracking availability, it's not optimal.

posted 7 years agoWe send notifications without any delay. If you use our Facebook Messenger bot to receive notifications you have to view every notification we send you in order to be able to receive new ones. This is a restriction by Facebook, which requires the user to interact with the bot to prevent spam.
It is correct that we update tracked products hourly. This is the best we can do for tens of millions of tracked products. Very popular ones are updated more frequently though.

- Rated 1 out of 5by Firefox user 20099617, 17 hours agoAsking new permissions to get personal infos sadly. Used it for years, time to remove another filthy addon from someone one wants to make money behind your back selling infos. Let's find an alternative ...
- Rated 1 out of 5by korbitr, 19 hours agoInstalled this as a replacement for Honey's price tracking, and now they want permission to collect my data as well. No thank you, I'll use the old version until it stops working.
- 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". - Do NOT post BAD reviews if you are not aware of this information (from Keepa support):
"Nothing about how Keepa handles data changed in this update. 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. This unfortunately triggers the "collecting browsing history" permission.
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."
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
