The government will let corporations pump high fructose corn syrup into everything on the shelf, despite heart disease being the #1 killer in America. But you need $35,000 in permits to sell homemade salsa to your neighbor, because you never paid off Congress with lobbyists.

If you need receipts for warranties or returns, photograph them immediately before they fade. For privacy purposes, understand that keeping or discarding receipts doesn't affect the digital records that exist. Cash purchases at stores without cameras create the fewest records.

Thermal receipt paper fades, but the transaction record doesn't.

That receipt you kept for warranty purposes will be blank in a few years. Meanwhile, the merchant, the payment processor, and the bank all have permanent records of what you bought, when, and where. The paper is ephemeral, but the data isn't.

Stop relying on receipts for records and consider what permanent transaction logs exist about you.

Anyone with an internet connection can search your Bitcoin balance, trace your transaction history, and link it to your identity
but tell me again how "number go up" makes that a feature and not a catastrophic design flaw.

Black and white laser printers generally don't include these dots. If you must print anonymously, use a printer you don't own, purchased with cash, from a public location. The EFF maintains a list of printers known to embed tracking codes.

Most color printers embed invisible tracking codes on every page.

These machine identification codes, also called printer dots, encode the printer's serial number and timestamp on every printout in a pattern invisible to the naked eye. The NSA leaker Reality Winner was caught partly because of these dots.

If you're printing something sensitive, know that the printout itself may identify the printer used.

Some gyms sell aggregated data to brokers. Others have been breached repeatedly. If your gym requires a membership card, you're logged every time. Vary your schedule occasionally, or choose gyms with less surveillance.

Gym access logs track when you work out down to the minute.

Card scans at entry and exit, equipment check-ins, class registrations. If your gym sells data or gets breached, your fitness schedule becomes part of your public profile. Combined with other data, this reveals when you're not home.

Your gym knows when you're not home. So does whoever buys their data.

If you've moved and haven't updated your microchip registration, do it now. Consider whether the address on file needs to be your home or whether a PO Box works. For high-threat individuals, this is another vector that often gets overlooked when hardening other areas.

Pet microchips and registrations link animals to owners.

When you chip your pet, that database entry contains your name, address, and contact info. Pet licensing, vet records, and adoption paperwork all create associations. Someone looking for you could find you through your pet.

Your pet's microchip database entry contains your name, address, and phone number. Someone looking for you could find you through your dog.
