Portfolio Sweep is operated by Groundwave Labs LLC. This page explains, in plain English, what information the service collects, what it is used for, and what it never does. The short version: we collect the minimum needed to run your watchlist, we never sell personal information, and there is no advertising or third-party analytics tracking in the service.
Your email address. Portfolio Sweep signs you in with a link sent to your email — there is no password. We store your email address to send those sign-in links and to keep your account separate from everyone else's.
The things you create in the app. Your watchlist, your journal entries and reads, your price-alert settings, and your preferences (such as Calm mode) are saved to your account so they follow you across devices.
Basic technical logs. Our hosting provider automatically records standard technical information when the service is used — things like IP address, browser type, and the times of requests. We use these logs only to keep the service running and secure.
On your device. Your browser stores your sign-in session locally so you stay signed in between visits. Signing out or clearing your browser's site data removes it.
Everything above is used for one purpose: operating Portfolio Sweep for you. That means signing you in, saving and showing your watchlist and journal, checking the price alerts you set, and sending the emails the service needs to work. Transactional email — your sign-in links — is delivered through our email provider, Resend.
Prices come from Financial Modeling Prep, and crypto symbol search uses CoinGecko. When you load your list or search for something, the ticker symbols involved are sent to those providers so they can return data. Your email address is not sent to them.
We do not sell personal information. We do not share it with advertisers, and Portfolio Sweep carries no advertising. There are no third-party analytics trackers in the service — no Google Analytics, no advertising pixels, nothing quietly watching you across other sites. Your data is not used to train AI models, and no AI system processes your journal or account information.
Your account information is kept while your account exists. If you would like your account and its data deleted, email us at the address below and we will remove it. Market data cached by the service (prices for symbols, not tied to you) may be kept separately.
The service runs over encrypted connections, sign-in links expire after 15 minutes, and account data is stored with our hosting provider, Netlify. We take reasonable steps to protect your information, but no online service can honestly guarantee absolute security — please treat your sign-in link like a password and do not forward it.
Portfolio Sweep is an educational tool for adults learning about markets. It is not directed at children under 13, and we do not knowingly collect information from them.
If this policy changes in a meaningful way, we will update this page and its “Last reviewed” date below. The version posted here is the one that applies.
Questions about privacy, or a request to delete your account and its data: support@portfoliosweep.com.
