About this app

Open Sync turns every card transaction into a clean, organized record. automatically and in real time. No screenshots, no spreadsheets, no
manual entry.

▌ HOW IT WORKS
The moment a card transaction happens, Open Sync captures the merchant,
amount, currency, last four digits of the card and the time of the
purchase. It then enriches every payment with merchant details and the
location where it happened, and stores everything locally on your device.

▌ WHAT YOU GET
• Every card transaction captured automatically, including small daily
ones you would normally forget.
• A clean monthly view with the current month's count and the last six
months at a glance.
• Each payment tagged with its real merchant name and approximate
location — so you can spot patterns and recognize unfamiliar charges.
• Optional sync to your work account when your company uses Open Sync
for expense reporting.

▌ PRIVACY FIRST
Your transactions are stored encrypted on your device. Open Sync never
reads your messages, your contacts, or your camera roll.

▌ KEY FEATURES
• Automatic transaction capture for major Spanish and European banks
• Reverse-geocoded location on every payment
• Encrypted local database (SQLCipher)
• Biometric unlock (fingerprint / face)
• Dark and light themes
• Multi-language: English, Español, Français, Italiano, Deutsch
• Manage multiple cards and decide which to monitor
• Works offline; syncs when you reconnect

▌ WHO IS IT FOR
• Freelancers and employees who need to expense card payments without
the receipts-in-a-shoebox routine.
• Anyone who wants a real, automatic record of where their money goes —
without uploading bank credentials anywhere.

▌ PERMISSIONS
• Notification access — required to detect card transactions as they
arrive on your device. Open Sync only reacts to the banking apps you
authorize and never reads anything else.
• Location (optional) — to tag each payment with where it happened.
• Battery optimization exclusion — so the service keeps working when
the screen is off.

▌ ABOUT
Open Sync is built by Wenalyze, a Spanish company specialized in
turning payment data into actionable financial insights for businesses
and individuals.
