Digital footprints
The small records daily life leaves — and which ones someone close can read.
In plain words
Bank cards, transit cards, and photos all leave small records. Think about who can read each record, not just whether one exists.
Beyond the browser
Bank and card statements list where you were and when. Transit cards, loyalty programs, rideshare and delivery histories, pharmacy records, and package tracking each keep their own trail. A person with access to shared accounts can read many of them without touching your phone.
Photos and posts
Photos can embed the location where they were taken, and friends' posts can place you somewhere as reliably as your own. Location tags, check-ins, and even reflections and backgrounds in images have been used to find people.
Thinking in trails
The useful question is rarely 'am I leaving a trace?' — you almost always are. It's 'who can read this trace, and when?' Cash leaves less than cards; new accounts leave less than shared ones; a trusted friend's address leaves less than your own.
What this does NOT protect against
- Statements and histories on accounts the other person shares
- Other people's posts and photos that include you
- Records held by companies, reachable through the account owner
- Old backups containing things long deleted from the device
