Questions
Before you install.
Will Android show a security message?
Yes. Android asks for permission when an app is installed directly from a website. Trejji Collect is delivered over HTTPS and signed so future updates must come from the same publisher key.
What happens if I cancel annual access?
Renewal stops, but unlimited access continues until the end of the period already paid. After that, your data remains available and the app returns to the free 25-product limit.
Does Trejji store my collection in the cloud?
Your working inventory, images, and sales records remain on your device. You control portable ZIP backups for moving or restoring your data.
Will an update erase my inventory?
No. Updates use the same Android package and signing identity, so they install over the existing app while retaining its local data.
