What Happens to a Receipt Photo After You Scan It? A Plain-English Guide
When an app says it uses "AI" to read a receipt, that almost always means the photo is sent to a cloud-based model to extract text and numbers, the same basic process as optical character recognition, just with a more capable model behind it. The part that actually matters for your privacy isn't whether AI is involved, it's what happens to that image after the text has been extracted.
Three things can happen to that image
It gets stored on the app's own servers, often indefinitely, building a growing archive of every receipt you've ever scanned, tied to your account.
It gets processed by a third-party AI service and then discarded, with the app itself never retaining a copy.
It never leaves your device at all, with only the extracted text, not the image, used for anything beyond the device.
These are meaningfully different outcomes, and a privacy policy will usually tell you which one applies, if you read the right section.
How to check which one applies to an app you're using
Search the privacy policy for the words "store," "retain," or "archive" near any mention of images or receipts. If the policy is silent on whether images are stored, that silence is itself information, well-written privacy policies are specific about this because regulators increasingly expect them to be.
Also check whether the app names which AI service does the processing. A specific, named provider with its own published terms is a better sign than a vague reference to "our AI" or "machine learning technology."
How Bill Breaker handles it
Bill Breaker uses Google's Gemini API to read each receipt and extract items and prices. The image is processed for that single task and is not saved, stored, or archived on Bill Breaker's own servers, it stays on your device. The Gemini API's own handling of the image during processing is governed by Google's terms, which is worth knowing if you want the full chain of custody, not just the part Bill Breaker controls.
When it's time to settle, Bill Breaker hands you off directly to Venmo or generates a PDF, it doesn't see or retain anything about the actual payment. The only other data point shared with a third party is an anonymous purchase token sent to RevenueCat, used solely to confirm subscription status, unrelated to your receipts or spending.
That's the model: a receipt passes through, gets read, and the image itself has nowhere to sit afterward.
