Privacy Policy
Last updated: October 22, 2026
This policy describes how amazon-oa.com handles information when you visit. The site is operated by Piyush Chhabra. It does not require an account.
Information this site collects
You can read every page without submitting personal information. The site does not have a signup form, a comment form, or a payment form. If you email hello@piyushchhabra.com, Piyush Chhabra receives whatever you include in that message and uses it to read and reply. Email is kept only as long as needed to handle the request. Please do not send confidential assessment content.
Hosting
The site is hosted on Vercel. Serving a page involves ordinary connection data, such as IP address, browser type, and the URL requested, which a host processes to deliver the site and protect the service. The operator does not keep a separate database of visitors and does not sell personal information.
Analytics
Pages include Vercel Web Analytics so the operator can see aggregated visits, such as which pages are viewed. Vercel states that this product does not use cookies and that it distinguishes a visit with a hash created from the request. Vercel states that the hash is discarded after 24 hours rather than stored as a permanent identifier. Published data points include the page URL, referrer, coarse location, browser, device type, and a timestamp. That analytics data is not used to choose ads.
Vercel describes the product at https://vercel.com/docs/analytics/privacy-policy.
Advertising, Google AdSense, and cookies
The homepage may show one advertisement through Google AdSense. Google is a third party. Google and its advertising partners may set or read cookies on your browser when an ad loads. Those cookies include the DoubleClick cookie and other Google advertising cookies. They are third-party cookies: they are set by Google, for example on doubleclick.net or related Google advertising domains, not by amazon-oa.com.
Google may use the DoubleClick cookie and similar advertising cookies to serve ads on this site, to measure how those ads perform, to limit how often you see an ad, and to personalize ads based on your visits to this site and other sites.
You can manage personalized ads, including opting out of personalization, in Google's ad settings at https://adssettings.google.com.
Google explains how it uses cookies and similar technologies for advertising at https://policies.google.com/technologies/ads.
You can also block or delete cookies in your browser. The pages on this site should still be readable if you do. An ad may load differently, or not at all.
Links to other sites
The homepage links to public posts on third-party sites such as LeetCode, Reddit, and X. Those sites have their own privacy practices. Following a link leaves amazon-oa.com, and this policy does not cover what those sites do.
Children
This site is not directed at children under 13, and the operator does not knowingly collect personal information from children.
Your requests
If the law where you live gives you a right to access, correct, or delete personal information an operator holds, email hello@piyushchhabra.com. Most visits do not give this site a record it can tie back to you. Advertising cookies are controlled by Google, through the ad settings linked above, and through your browser.
Changes
This policy may be updated as the site changes. The date at the top of this page will change when that happens. The same policy is published at /privacy-policy and /privacy.
