Privacy Policy

1. Overview

Idea Radar can be used without an account for a limited number of free searches per day. Signing in with Google unlocks a higher daily limit, saved ideas, and paid features (credits and Idea Alerts). We only collect what's needed to run those features, described below.

2. Account & sign-in

If you sign in with Google, our authentication provider (Supabase) stores your name, email address, and profile picture to identify your account, and keeps you signed in via a session cookie (see Cookies, below). We use this only to run the product — to know who you are, enforce your daily limit, and save ideas to your account — not for marketing or sale to third parties.

3. Payments

Paid features (credits, Idea Alerts, Book Builder subscriptions) are billed through Stripe. We never see or store your full card details — Stripe handles payment collection and storage directly, under its own privacy policy.

4. Email features

If you use "Email me these ideas" or subscribe to Idea Alerts, we store the email address you provide (or your account's sign-in email) solely to send that specific email, via our email provider, Resend. If you sign up for our occasional email updates (the form in the site footer), we store that address with Resend to send you those updates, and any such email includes a one-click unsubscribe link. We don't sell or share any of these addresses, and Idea Alerts can also be cancelled anytime from your account.

5. Idea generation requests

When you generate ideas, the topic and niche you enter are sent to our server to produce results. To do this, we may query third-party data sources — Google Trends, Reddit's public search, and, optionally, Keywords Everywhere, Etsy, and Anthropic's Claude API — using only the topic/niche text you submitted. We don't attach any identifying information to these requests, and we don't store the queries or results server-side after the response is returned to your browser.

6. What's stored locally, on your device

If you're not signed in, your saved ideas and last search are stored only in your browser's localStorage — on your device, not on our servers. This data never leaves your browser, is not visible to us, and does not sync across devices. Clearing your browser data or using a different browser/device will remove it.

7. Cookies & analytics

We use a small number of cookies to run the product: a session cookie from our authentication provider (Supabase) that keeps you signed in, and a short-lived anonymous identifier cookie (idea_radar_anon_id) that lets us enforce the daily free-search limit for guests who aren't signed in. Neither is used for advertising or cross-site tracking.

We also use Vercel Analytics for aggregate traffic and performance metrics (e.g. how many people visited a page, how fast it loaded) -- it doesn't use cookies or collect personal information. If we enable Google Analytics (GA4) in the future, that will set its own cookies to measure usage, and we'll update this section to say so plainly when it's on.

8. Advertising

This site may display advertisements served by Google and other third-party advertising companies, including through Google AdSense. These companies may use cookies — including Google's advertising cookies — to serve ads based on your visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings, or, for third-party vendors generally, via aboutads.info. If you are located in the European Economic Area, the UK, or Switzerland, we will seek your consent before showing personalized ads or setting related cookies, in line with Google's EU User Consent Policy.

9. Children's privacy

Idea Radar is a tool for creators and sellers, not a service directed at children, and we do not knowingly collect personal information from anyone under 13. The Book Builder feature lets an adult user generate a coloring book intended for a chosen age group (including children) as the finished product — this doesn't involve collecting any information from a child.

10. Changes to this policy

If this policy changes as the product evolves, we'll update this page and change the date above.
