A receipt looks trivial. It isn’t. Put a year of them together and you have a detailed map of someone’s life: where they go, when, how much they earn and spend, what they eat, what medications they buy, where they travel. That’s exactly the kind of data most apps quietly ship to the cloud the moment you take a photo.
PKTD is built the other way around. Here’s why that matters.
The hidden cost of “free” cloud scanning
When a receipt app uploads your images to its servers, a few things become true whether you think about them or not:
- Your spending history now lives on someone else’s computer, subject to their security, their breaches, and their business model.
- Receipt images often contain partial card numbers, names, and locations — sensitive by anyone’s definition.
- Cloud data can be retained, analyzed, or shared in ways that are easy to bury in a privacy policy.
None of this is hypothetical. Data breaches are routine, and “we take your privacy seriously” is doing a lot of work in a lot of policies.
What “on-device” and “local-first” actually mean
On-device means the heavy lifting — reading the text off your receipt — happens on your iPhone using Apple’s built-in Vision OCR, not on a remote server. Local-first means your receipts, categories, and totals are stored on your device by default, not in a company database.
With PKTD specifically:
- Receipt images never leave your iPhone.
- Text is extracted on device; image metadata like GPS is stripped before the processed image is saved.
- Your ledger lives locally, and if you choose to sync, it goes through your own private iCloud — not our servers.
”But doesn’t AI need the cloud?”
Not for most receipts. On-device OCR handles the large majority of everyday receipts entirely offline. When a receipt is genuinely messy and optional AI assistance is used, it’s a fallback you control — not the default path your private images travel by.
That hybrid approach is the point: you get the accuracy of modern parsing without making cloud upload the price of admission.
Privacy is a tax feature too
There’s a practical upside beyond peace of mind. Because your records are yours and stored faithfully on your device, you keep clean, audit-ready receipts for the CRA’s six-year window without depending on a third party to still exist — or still hold your data — years from now.
The bottom line
You shouldn’t have to trade your financial privacy for a tidy expense list. On-device, local-first scanning gives you both.
