Privacy policy

Last updated: November 1, 2026

This policy explains what information StockSlicer LLC (“StockSlicer,” “we”) collects when you use stockslicer.com or the StockSlicer New Tab browser extension (which shows stockslicer.com in your new tab), how we use it, and your choices.

What we collect

• Account information. If you create an account: your email address, your first name if you give it (we use it only to greet you), and a securely stored (hashed) password, or just your email if you sign in with an emailed link.
• Signing in with Google. If you choose “Continue with Google,” Google shares your name, email address and profile picture with us. We use them only to create and sign in to your StockSlicer account. We don’t access your Google contacts, files, email or anything else, we don’t sell this information, and we don’t use it for advertising. You can remove StockSlicer’s access at any time in your Google Account’s security settings.
• Your watchlist and settings. The companies you choose to watch, whether you want earnings alerts or the weekly summary, and the city you pick for the background scene. Only you can see them.
• Your portfolio. The tickers, share counts and optional purchase prices you enter. Only you can see them; our database rules block other users from reading them.
• Questions to the assistant. The questions you type and the numbers on the page you’re viewing, sent to produce an answer. We don’t store conversations ourselves.
• Basic technical information. Your IP address is used briefly to limit how many assistant questions each visitor can ask per day, and our hosting providers keep standard server logs.
• Your location, only if you add it. The site doesn’t guess where you are. Your local time comes from your device’s own clock. To see your city’s weather, you can add your location in Settings, either by typing your city or by choosing “Use my location.” If you type a city, the name is sent to Open-Meteo, a free weather service, to look it up. If you use your location, your browser asks your permission first; we round your coordinates to about 1 km and send them to BigDataCloud to find the city name. Either way, the city and its rough coordinates are saved only in your browser and sent to Open-Meteo for the forecast. If you allowed location, the site refreshes it when you open the page, so it follows you when you travel. You can remove it in Settings at any time, and we don’t store it.
• On your own device. The site stores a few things in your browser: your settings (like the time-of-day scene), your watchlist and portfolio when you aren’t signed in, and whether you’ve seen the page tour. These stay on your device, and signing out clears your lists from that browser.

We don’t collect your brokerage logins, bank details or payment information.

Google user data

If you sign in with Google, StockSlicer receives only your basic profile: your name, email address and profile picture (Google’s “openid,” “email” and “profile” permissions). We use them for one purpose: to create your StockSlicer account and sign you in. We store your email address with your account; we don’t store your Google password and never see it.

We don’t sell Google user data, share it with anyone except the service that runs our sign-in (Supabase), use it for advertising, or use it to train AI models. StockSlicer’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. To remove StockSlicer’s access, visit your Google Account’s “Third-party apps & services” page, and email us to delete your StockSlicer account and data.

How we use it

To run the Service: sign you in, save and show your portfolio, answer assistant questions, prevent abuse, and keep the Service working. We don’t sell your personal information and don’t use it for advertising.

Who processes it for us

• Supabase: accounts and saved portfolios.
• Cloudflare: hosting the site and its server.
• Anthropic: the AI model behind the assistant receives your questions and the page’s numbers to write answers. See Anthropic’s policies for how it handles API data.
• Resend: sends the emails you turn on (earnings alerts and the weekly summary) to your email address.
• Google: signs you in if you choose “Continue with Google.”
• Open-Meteo: provides the weather shown on the home page; it receives the rough coordinates of the city you added (or the city name you type in Settings), never your name or email.
• BigDataCloud: if you choose “Use my location,” turns your rounded coordinates into a city name; it never receives your name or email.
• Marketstack: provides closing share prices; it receives only the ticker symbols being looked up, nothing about you.
• TradingView: shows share prices and news in boxes on some pages. Those boxes load from TradingView, which may use its own cookies; StockSlicer doesn’t send TradingView your account information.

Your choices

• Use StockSlicer without an account; portfolios then stay in your browser.
• Edit or remove holdings any time on the portfolio page.
• Ask us to delete your account and data: hello@stockslicer.com. We’ll do so within 30 days.
• Depending on where you live, you may have more rights (such as access or correction). Contact us to use them.

Security and retention

Data is sent over encrypted connections and access is limited by database rules. We keep account and portfolio data until you delete it or ask us to. No system is perfectly secure; we’ll notify you as required by law if a breach affects your data.

Children

StockSlicer isn’t directed at children under 13, and we don’t knowingly collect their information.

Changes and contact

We’ll update this page and the date above if our practices change. Questions: hello@stockslicer.com, or by mail: StockSlicer LLC, 1835 N Main St, Las Cruces, NM 88001.
