Privacy Policy

What we collect, by feature

Browsing the site. Like any website, our host (Vercel) receives your IP address, browser user agent, the page you asked for including its full URL, and the referring page. We use Vercel Web Analytics and Vercel Speed Insights to count page views and measure page speed. Neither one uses cookies. Vercel identifies a visit with a hash of the request that is discarded after 24 hours, and it can't follow you across other sites. Analytics records the page URL, referrer, country and city-level location, browser, operating system, and device type. Product logos are files we host ourselves.

The quiz. Your quiz answers (for example the category, the tool you're replacing, team size, and constraints) are stored in the page URL. They are not stored in an account or a database. That makes a result easy to share, but anyone you give the link to can see the answers. The URL also shows up in our host's request logs and in analytics like any other page address. We record anonymous events such as "quiz started" or "quiz completed", tagged with the category and the tool being replaced.

Email me this shortlist. If you enter your email on a results page, we use it to send you that shortlist once, through our email provider, Resend. The operator may receive a copy so delivery failures can be followed up. We don't add you to a newsletter.

Migration Agent. When you ask for a migration plan or chat with the agent, we send what you typed (the tools you're moving from and to, company size, stack notes, constraints, and chat messages) to OpenAI so a model can write the answer. OpenAI processes it under its API terms. We don't publish a separate retention number for that account. We don't save plans or chats in a database. They stay in your browser tab. Stack notes and constraints are not put in the URL. Don't paste passwords, API keys, customer data, or anything confidential.

Talk to a specialist. If you request a migration specialist, we collect your name, email, company (optional), a note, and the migration you're planning. Afterstack makes the introduction by email to a services partner. We don't automatically forward the full form to a partner without review.

Reviews. If you submit a review, we collect your rating, the review text, why you left the tool, your company size, and optionally your name and email. If we publish the review, it shows your first name and company size, never your email. We may edit for length or factual correction. Reviews never change quiz rankings.

Product questions. We collect your question and, optionally, your name and email so we can reply. Questions are not published until we review them.

Vendor claims and screenshots ("Broaden Your Reach"). Vendors who claim or submit a listing give us their company name, website, listing type, category, a contact email, an optional note, and optional screenshot links with captions. Screenshots are held unpublished until we review them, and are only shown if the submitter confirms they have the right to license them for display. Claiming a listing or paying for placement never changes rankings.

Affiliate links. Some "Visit site" buttons go through afterstack.ai/go/[product]. We record an anonymous click event (which product), then send you to the vendor. Some links carry a referral code so the vendor can credit us for the visit. After that the vendor's own privacy policy and cookies apply, not ours. See our advertising disclosure. The products on that page are the ones with a live referral link. There is no sitewide affiliate banner.

Where form submissions go

When you submit a form above, the details are:

• emailed to us through Resend so we can act on them, when email delivery is configured;
• written to server console logs with personal names and email addresses masked, and with free-text notes reduced to a character count. The host still records the request itself (IP address, user agent, and URL). Reviews and screenshot submissions also sit in private Vercel Blob storage.

Who else processes data

We share data beyond this list only when the law requires it, or as part of a sale or merger of the business.
