Privacy Policy
Effective October 22, 2026
Grail Watch is a browser extension that watches Grailed for listings you describe and alerts you when one appears. This policy explains what it handles and why. The short version: your grails stay in your browser, and the only personal information that leaves it is your email address, used to send you the alerts you asked for.
What stays on your device
Your grails (search terms, filters, sizes and prices), the matches found, and your settings are saved in your browser's extension storage. They are not sent to Grail Watch's servers. Removing the extension deletes them.
Searching Grailed
To check for new listings, the extension sends your grail's search terms from your browser directly to Grailed's search provider (Algolia), the same way grailed.com does when you search there. When you visit grailed.com, the extension reads the public search key from the page so that searches keep working. It does not read anything else on Grailed and never acts on your Grailed account.
Email alerts (optional)
Email alerts are off unless you sign in with Google. When you do:
- From Google we receive your email address and Google's account ID for you. We do not get your password, contacts, Gmail messages or any other Google data.
- When a match is found, the extension sends the listing's title, link, photo link, price and size, plus your grail's name, to the Grail Watch email server, which turns it into an email to your address.
- What the server keeps: a count of emails sent per account to enforce the daily limit (deleted automatically after two days) and a count of sign-in attempts per IP address to stop abuse (deleted after two hours). It does not keep a list of users, your grails or the emails it sends.
Who processes the data
- Cloudflare runs the Grail Watch email server.
- Resend delivers the alert emails and keeps delivery logs for a limited time.
- Google handles sign-in.
- Algolia answers searches on Grailed's behalf.
Grail Watch does not sell your information, use it for advertising, or share it with anyone else.
Your choices
Turn email alerts off or sign out any time in the extension's settings. Signing out removes your email address from the extension. You can also remove Grail Watch's access in your Google account settings. To ask a question or have anything deleted, email hello@grailwatch.app.
Changes
If this policy changes, the new version will be posted here with a new effective date.
