What we collect, and why

Waitlist. Your email address and, if you add one, a creator @handle. We use them for early-access news and the weekly trend digest; the handle only helps us pick trends for your digest. Every digest has an unsubscribe link. We also note which form you joined from — the home page or Pro early access — to count interest in Pro, and, if you joined by asking for a category we don't collect yet, which category you asked for and in which market.

Account. Signing in uses a one-time email link through Supabase, so we store your email address. With an account we keep what you choose to save — saved trends, your My Week plan, your feed setup (platform, market, niche, an optional channel), a claimed channel handle and whether you verified it, and whether you want the digest — plus each brief, remix, video review or channel analysis you run and its result, so we can count your allowance and never charge a retry twice.

Channel analyses. When you analyze a TikTok or Instagram handle, we fetch that account’s public profile and recent public posts and store the report. A completed report is a public page anyone with its link can open.

Questions, briefs and video feedback. What you type or paste — a question about a trend, your creator style, a video link, spoken words — is sent to OpenAI to write the answer. Trend questions are not stored.

Contact form. Your email, subject and message, stored and forwarded to our inbox so we can reply.

To keep free features inside their daily limits, we count requests per IP address per day. We also log three product events — sign-in, claiming a report, generating a brief — against your account, or against a random browser ID (the mt_anon cookie, set only when you claim a report before signing in).

Your browser keeps your language, saved trends, plan and creator style in local storage. They stay on your device unless you sign in, when saved trends and your plan sync to your account. Filming plans you get on the trends page or in For You are kept in this browser for 14 days, separately for each account. When you sign in on another browser, or after clearing this one, the plans you got in the last 14 days are restored from the briefs your account already keeps. For “since you last looked”, the browser keeps the status of your saved trends and the verified trends you last saw, in this browser only.

Cookies: Supabase’s sign-in cookies while you are signed in, and mt_anon as above. The site loads no advertising scripts and nothing that follows you across other sites.

We count page views with Vercel Web Analytics, which sets no cookies. A page view records the page’s address (its path, feed filters such as category, market and language, and campaign tags such as utm_source; never a sign-in link or anything after “#”), the page that sent you here as your browser reports it (usually just the site), your browser, operating system and device type, and your country, read from your IP address. Vercel tells visits apart with a hash of the request rather than a cookie, and nothing ties a page view to your account.

Supabase (database and sign-in), Vercel (hosting and page-view counts), OpenAI (AI-written briefs, answers and reports), ScrapeCreators (fetches public TikTok and Instagram data for analyses and video feedback), Resend (digest email), our email provider (contact messages), jsDelivr (serves the Korean web font to your browser), and Stripe if you buy a plan — Stripe handles your card; we never see its number. We do not sell personal data.

Account: open Account and choose “Delete my account”. That removes your sign-in and everything stored with it — profile, saved trends, plan, preferences, usage records and events. Public channel reports stay published; ask us to take one down.

Waitlist and digest: use the unsubscribe link in any digest email.

Anything else: write to us through the contact page or at maketrendsai@gmail.com.
