Passing Through, last updated August 22, 2026
Passing Through is a road journal that runs on your phone. There's no account, no login, and no server holding onto your trips. Here's exactly what stays put, what leaves, and where it goes when it does.
What stays on your phone
All of it. Your route, your miles, the places you stopped, your notes, your photos, your pay records, your supply lists. Every bit of that lives in a database on the device and nowhere else.
No copy sits on a server. Nobody here can read your journal, because there's nothing to read. Delete the app and the whole thing goes with it.
What leaves your phone, and where it goes
Four services get your location straight from your phone, so the app can figure out what's around you:
- Wikipedia, for places nearby worth knowing about
- OpenStreetMap, for historical markers and points of interest
- Open-Meteo, for weather on your route
- Apple, to turn coordinates into the name of a town
Those requests carry your coordinates and your phone's IP address. No name, no account, nothing tying one request to the next. Each of them has its own privacy policy, and once a request lands there, what happens to it is up to them.
One more service gets text, but never location:
- Passing Through's own server, which writes the notes you hear while driving and the message on your weekly postcard. It gets the name of the state you're in, public Wikipedia text about nearby places, the towns you drove through, and — for the postcard — short pieces of notes you wrote yourself. It does not get your coordinates.
That server hands the text to Anthropic, which writes the words, and to Microsoft Azure, which reads them out loud.
What those two keep
Anthropic may hold the text of a request for up to 30 days, to watch for misuse, and longer if something gets flagged. Their agreement with us says your text is never used to train their models.
Microsoft Azure doesn't store the text it speaks or the audio it makes.
Neither one gets your name, your location, or anything that points back to you or your phone.
The part worth reading twice
The postcard is written out of your own words. Write a note during the week and a short piece of it may go to Anthropic, so the message reflects the week you actually had. That's the most personal thing this app sends anywhere. You can turn it off, and the postcard will be written from the route instead.
Trip dictation. Say a trip into the Truck screen and the words are sent to Anthropic to be turned into a trip record — load number, pick-up, delivery, miles, stops. That's text you spoke about your work, and after your postcard notes it's the most personal thing this app sends anywhere. We don't keep it. Anthropic holds a copy for up to 30 days for abuse checks, then deletes it, and doesn't train on it. No GPS data rides along, and neither does your name — but whatever you say does, including the towns and the load number. You're asked before the first time, you can turn it off in the drawer, and typing a trip never leaves the phone.
What we don't do
- No accounts, no sign-in, no email address required
- No ads, no ad networks, no trackers, no analytics
- Nothing sold, nothing shared with anyone not named on this page
- Nothing you write trains an AI model
- Nobody is watching your drives. There's no server that could.
Children
Passing Through isn't built for kids under 13 and isn't aimed at them.
What you control
- Turn off the tour guide and no text goes to our server at all
- Turn off location and the app records nothing
- Delete the app and everything goes with it
