Bar CostPrivacy notice
Last updated October 16, 2026. In plain language: what Bar Cost collects, and why.
The app
Everything you enter in the app (bottles, prices, cocktails, distributors, counts and orders) is saved in your own web browser, on your device. If you don't sign in, it stays there and isn't sent to us or anyone else. Clearing your browser's site data deletes it, so use Backup in the app to keep a copy.
If you sign in
Signing in is optional. If you do, we store your email address and a copy of your bar's data in your account, so you can use it on any device.
- Why: to sign you in (we email you a sign-in link, or you continue with Google) and to keep your bar saved online.
- Signing in with Google: Google shares your name, email address and profile picture with us. Our sign-in provider keeps them with your account; the app itself uses only your email address, to sign you in and to match team invites.
- Where: in a database hosted by Supabase, our service provider. Your account can read and change its own bar. If an owner adds your email to their team, your account can also read that bar; as a Manager it can change it too, and as Staff it can send counts and cocktail ideas to it.
- Who can see it: you, and the Bar Cost team when needed to run the service or help you (for example, to fix a problem you report). We don't sell it, share it or use your prices for anything else.
- How long: until you ask us to delete your account. Signing out removes your bar from that browser but keeps it in your account.
The waitlist
If you join the waitlist, we store the details you give us: your email address, and optionally your bar or business name, your role, your number of locations and the plan you're interested in, plus the date you joined.
- Why: to email you about Bar Cost's launch and early access, and to understand who the product is for.
- Where: in a database hosted by Supabase, our service provider.
- Never: sold, rented or shared for anyone else's marketing.
- How long: until launch, or until you ask us to remove it.
Your choices
To see, change or delete your waitlist details or your account and its data, or to stop hearing from us, email us. Every launch email will also include a way to unsubscribe.
Invoice scanning
If you scan an invoice, the photo or PDF is sent to Anthropic, whose AI model (Claude) reads the line items and sends them back to the app. We don't store the image, and Anthropic processes it only to provide this service. The lines you choose to receive are saved with your bar like everything else. Sales exports you import (for example from Toast) are saved with your bar too.
Feedback
If you send feedback from the app, we store your message, the email you give (optional), which screen you were on and your browser type, to read it and reply. It isn't used for anything else.
Error reports
If something goes wrong in the app, it sends us a short error report so we can fix it: the error message, where in the app's code it happened, the page, and your browser type. It never includes your bar's data, and isn't linked to your account.
Hosting
The site is hosted on Firebase (Google), which, like any web host, processes basic technical data such as IP addresses to deliver pages. The site loads its font from Google Fonts.
