PRIVACY POLICY

Overview

StackItUp (“we”, “us”) helps you generate a personalized supplement stack. This policy explains what we collect, why, and the choices you have. We try to collect as little as possible.

What we collect

• Quiz answers.Stored in your browser’s local storage. We don’t send them to our servers unless you sign in and save a stack to your account.
• Account info. If you sign in with Google, we receive your name, email, avatar, and Google user ID via Supabase Auth.
• Profile data. Anything you add on your settings page (username, bio, public profile fields).
• Newsletter email. If you subscribe, we store your email to send occasional updates.
• Analytics. We use Umami for privacy- friendly, cookie-less page analytics (pages viewed, referrer, rough region). No personal identifiers are collected.

How we use it

To generate your stack, render your account pages, send the newsletter if you opted in, and understand which parts of the site are useful. We don’t sell your data and we don’t run third-party advertising.

Who we share with

Service providers that make the site work: Supabase (auth, database, storage), Vercel (hosting), Google (OAuth sign-in), Stripe (payments — card details are handled directly by Stripe and never touch our servers), and Umami (analytics). Each only gets what they need to do their job.

Your choices

• Clear your browser storage to wipe quiz answers on your device.
• Unsubscribe from the newsletter via the link in any email.
• Delete your account or request your data by emailing matt@delac.io.

Not medical advice

StackItUp is educational. Nothing here is medical advice. Talk to a qualified professional before starting any new supplement — especially if you’re pregnant, nursing, or on medication.
