Photo, GPS, or Manual: where each day comes from
Every day in your timeline is backed by evidence, and Bounded remembers which kind. Three sources feed the record — and when they disagree about a day, a strict priority order decides.
The three sources
- Photo — days reconstructed by the photo scan from GPS tags on your pictures. Great for the past; only as dense as your photo habit.
- GPS — days logged by Smart Tracking as you travel. The going-forward source: automatic and photo-independent.
- Manual — trips you entered or edited yourself, including calendar gap fills.
Who wins when they disagree
Manual beats GPS beats Photo. Your explicit word is always final — editing a day overrides whatever was detected. Live location beats a photo’s tag, since a photo can be a saved image or an outlier while GPS reflects where the phone actually was. In practice this means you can always fix the record, and automatic data can never quietly undo your fix.
- Re-sync from photos rebuilds only the photo layer — manual and GPS days survive every re-scan.
- Erase auto-detected data (Settings → Data) removes the photo and GPS layers and keeps manual ones.
Where you can see the source
The day-by-day exports carry a source column — Photo, GPS, or Manual, per day — which is exactly what makes the record credible to a tax authority: it distinguishes evidence from recollection.
