Privacy policy

Last updated October 4, 2026

Revierdict is a browser extension, with this website, that finds YouTube reviews of the Amazon product you're looking at and sums them up. This page explains what it collects and why. In short: it only sends what it needs to find and summarize reviews, nothing is tied to you, and nothing is sold.

What the extension sends, and when

Nothing is sent until you click one of its buttons.

• When you click "Search YouTube For Reviews" on an Amazon product page, the product's name, brand and page link (which includes its Amazon product ID) go to revierdict.com, which searches YouTube for reviews of it and checks them.
• When you click "Summarize transcript" on a review, your browser downloads that video's captions from YouTube. The captions, the video's ID, title and channel, and the product's name and ID then go to revierdict.com, which writes the summary.

To search YouTube and download captions, your browser contacts YouTube directly, as it does when you visit youtube.com. YouTube's own privacy policy covers those requests.

What it doesn't collect

No account, name, email address or payment details. No browsing history: the extension only runs on Amazon's sites, only adds its button to product pages, and only reads the product's name, brand and ID when you click it. It never uses or reads your Amazon or YouTube accounts. It has no ads, and no tracking or analytics.

How it's used

• To find a product's YouTube reviews, judge which look independent, and summarize them, using AI models run by third-party providers (currently reached through OpenRouter and Groq). They receive the product details and captions described above, and nothing about you.
• To show each summary as a page on revierdict.com.

What's kept, and for how long

• Search results are saved for 7 days, so the same search isn't repeated.
• Summaries are kept, and each one is a public page at revierdict.com/s/… so it can be shared. A summary page shows the product, the video and the AI's summary, and nothing about the person who asked for it.
• Usage counts: the server keeps a private log of AI usage and cost (for example "one summary, so many words"), with no information about you.
• Hosting logs: revierdict.com is hosted by Vercel, which keeps standard request logs (such as IP address and time) for a short period.
• In your browser: the extension keeps the details of the videos it found (title, channel, caption link) for up to 30 minutes, so summarizing one doesn't mean looking it up again. This is cleared when the browser closes.

Sharing

Revierdict doesn't sell data, and doesn't share it except with the services that run it (the AI providers and the host, above), for the purposes described here.

Affiliate links

The Support page on revierdict.com turns an Amazon product link you paste into Revierdict's affiliate link for that product. As an Amazon Associate, Revierdict earns from qualifying purchases made through it. A full link is read in your browser; a short link (such as a.co or amzn.to) is sent to revierdict.com, which asks Amazon where it leads and doesn't keep it. If you open the link, Amazon may set its own cookies, and Amazon's privacy notice applies on Amazon's site. Summary pages link to the product on Amazon without an affiliate tag.

Children

Revierdict isn't directed at children under 13 and doesn't knowingly collect anything from them.
