BillChecker3000
Last updated June 2026
BillChecker3000 helps you spot overcharges on bills, quotes, invoices, and receipts. To do that, we have to look at what you upload. This page explains exactly what we collect, how we use it, and who we share it with — in plain English.
Account info: the email address you sign in with, plus an Apple or Google sign-in ID if you choose those options.
Bill content: the photo or PDF you upload, plus everything we extract from it — vendor name, line items, prices, totals, dates.
Approximate location: we ask for your location to find accurate area pricing. We only store the first 3 characters of your ZIP/postal code (e.g. "606" for the Chicago area) plus city, region, country. We do not store your exact GPS coordinates or full ZIP.
Usage data: a record that you analyzed a bill, used to enforce the free-tier monthly limit.
We send your bill image or PDF to Anthropic's Claude AI for extraction and analysis. We use your approximate location to look up local pricing data — sometimes via web search, sometimes from aggregated benchmarks built from past BillChecker3000 users' data (always anonymized; never linked to specific people). We then generate a verdict and store it in your account so you can view it later.
For categories that often contain sensitive personal info — medical and legal — we automatically delete the bill image from our storage immediately after extraction completes. The extracted text and verdict remain in your account, but the original image does not. For other categories, images stay until you delete them or your account.
Supabase hosts our database, storage, and authentication. Anthropic processes bill images and generates verdicts via the Claude API, and does not train on your data. Stripe processes web subscription payments — we never see your card details. RevenueCat, Apple, and Google handle mobile in-app subscription payments.
As BillChecker3000 grows, we build region-level price benchmarks from extracted bill data — e.g. "median brake-pad replacement price in 606xx ZIP codes." These aggregates are not linked to any individual user and only publish once enough separate samples exist.
You can view all your past bills in the app, delete them individually, or delete your entire account (Account screen → Delete account), which removes all your bills, images, and account info. You can also email privacy@billchecker.app with any data request — to access, correct, or delete your information.
We do not sell your personal information, and we don't share it for cross-context behavioral advertising. We never have. If you're a California resident, you have the right to know what we collect, to delete it, and to not be treated differently for exercising those rights — all of which the app already supports above.
We keep your account info and bills until you delete them or close your account. Bill images for medical and legal categories are deleted automatically right after analysis. When you delete a bill or your account, the data is removed from our active systems promptly and rolls off routine backups within 30 days. We store only the minimum we need — for example, only the first 3 characters of a postal code, and we don't retain free-text bill notes or vendor street addresses.
Your data is encrypted in transit (HTTPS), and access controls mean you only ever see your own data. No system is perfectly secure, but we use industry-standard safeguards and keep the footprint of stored data small on purpose.
BillChecker3000 is not for children under 13. We don't knowingly collect their data.
We'll update this page when we change how we handle data. Material changes get an in-app notice.
