Privacy policy

Last updated November 14, 2026

Trendtok works without an account. If you sign in, we keep your email address and what you save. Here is everything we collect.

Clicks to stores

When you press Copy and open on a code, we record the store, the code, which of our pages you came from and the time. We use this to count how often each code is used. We don't record who you are.

“Did it work?” votes

When you vote, we save the vote with a one-way scrambled ID made from your IP address, browser and the date. It lets us count one vote per person per day. We don't keep your IP address. Your browser also remembers your vote so the button shows it next time.

Search

Searching runs in your browser. We don't send or store what you type.

Browser extension

The extension downloads our list of stores and matches the site you are on against it in your browser. On a product page of a store we list, it asks us for that product's price history, sending the store and the product's name from the address. We don't store these requests or link them to you.

On those product pages it also shares the product's price anonymously: the store, the product, the option we track, its price, was price, stock and currency, as the store's own page shows them. Nothing about you is sent with it. We use it only to see when a price may have changed, and then check the store ourselves. To limit abuse we keep a scrambled code made from your IP address and the date, never the address itself.

On a product page of a Shopify store we don't list yet, it sends us only that store's web address, at most once a day, so we can start tracking its prices. Nothing about you, the page or the product is sent.

Without an account, products you watch are saved only in your browser. Once a day the extension asks us for each watched product's price, the same request as above, and shows a notification when it drops. We don't know what you watch or the price you set.

The extension also remembers, in your browser, which stores you closed or minimised its card on.

Account (optional)

You can sign in from the extension with your email address. We email you a sign-in link and then keep your email address and your price alerts (the product, its link and photo, the price when you set the alert and your target) so they appear in any browser you sign in on and we can email you when a price drops. We use your email only for sign-in links and those alerts, never for marketing, and we don't sell or share it. Emails are sent through our email provider, Resend.

You can also sign in on this website, on the TikTok Shop pages, with your email address and a password, an emailed link, or Google. Sign-in runs through Google Firebase, which keeps your email address, a scrambled form of your password and, for Google sign-in, your Google account's name and photo. We then keep the TikTok Shop products you save (the product and its numbers when you saved it) so they appear in any browser you sign in on. If you sign in with the same email address on the website and in the extension, it is one account.

Every alert email has a link to stop alert emails. Signing out removes the account from that browser. To delete your account and everything in it, contact us.

Analytics and cookies

We don't use analytics tools or ad trackers. The only cookies are the two that keep you signed in on this website, set when you sign in and removed when you sign out. Our host, Vercel, keeps standard server logs (such as IP address and pages requested) for a short time to run and secure the site.

Stores and affiliate networks

Some links go through an affiliate network before reaching the store. Once you leave Trendtok, the store's and network's own privacy policies apply. See our affiliate disclosure.
